    Isolated sphenoid sinus lesions are an uncommon entity and present with non-specific symptoms. In this case report, the patient presented with a history of headaches for a duration of one month without sinonasal symptoms. A computed tomography scan showed a soft tissue mass occupying the sphenoid sinus. An endoscopic biopsy revealed fungal infection. Endoscopic wide sphenoidotomy with excision of the sphenoid sinus lesion was then performed however, the microbiological examination post-surgery did not show any fungal elements. Instead, Citrobacter species was implicated to be the cause of infection. PMID:25320694

    This paper describes a case of pneumatization of the sphenoid sinus in the pterygoid process and greater wing of the sphenoid bone, observed on a panoramic radiograph. Conventional radiographs and computerized tomography in axial and coronal sections confirmed the presence of the pneumatization of these structures.

  3. Sphenoid sinus mucocele presenting with oculomotor nerve palsy and affecting the functions of trigeminal nerve: a case report

    We report a case of first-episode sphenoid mucocele successfully treated via transnasal endoscopic drainage and marsupialization of the mucocele. A 55 year-old female presented with persistent right-side facial numbness (in the areas of the first and second branches of the trigeminal nerve) and right-side ptosis. Computed tomography (CT) imaging and Magnetic resonance imaging (MRI) revealed opacification and expansion of the right-side sphenoid sinus lesion. The lesion was diagnosed as right-side sphenoid mucocele affecting the functions of the trigeminal (first and second branches), and oculomotor nerves. Transnasal endoscopic drainage and marsupialization of the mucocele result in rapid regression of these symptoms. PMID:26629234

    Non-traumatic cavernous internal carotid artery (ICA) aneurysms are rare, and favour the occurrence of massive recurrent epistaxis, which is associated with a high mortality rate. We report the case of a 67-year-old woman presenting a ruptured ICA aneurysm extending into the sphenoid sinus, revealed by epistaxis. Selective coil embolization of the aneurysm was performed. Flow-diverter stents were deployed in order to utterly exclude the aneurysm and prevent revascularization. Anti-platelet treatment was provided to lower the risk of in-stent thrombosis. A left frontal hematoma associated with a subarachnoid haemorrhage occurred at day 2. Outcome was favourable with no neurological sequelae, and no clinical recurrence of epistaxis occurred. A 4 months follow-up digital subtraction angiography showed a complete exclusion of the aneurysm. In addition, a magnetic resonance cerebral angiography at 16 months showed stable results. Thus, this two-stage endovascular procedure has proven its effectiveness in preventing epistaxis recurrence while preserving the ICA patency. PMID:26494406

    We report the case of an 18-year-old male patient operated on for sphenoid sinus barotrauma after scuba diving. The patient attended our emergency department because of intractable headache but did not improve with conservative treatment. After computed tomography and magnetic resonance imaging examination, he was diagnosed with sphenoid sinusitis that extended to the nasal septum. He therefore underwent surgery for sinus ventilation and abscess drainage.

    Objective To describe the clinical presentation, pathophysiology and treatment of spontaneous cerebrospinal fluid (CSF) leaks of the sphenoid bone, with an emphasis on a previously undescribed form in this location, in which CSF is trapped under the mucosa of the sinonasal cavity or in the soft tissue of the skull base. Study design Case series and literature review. Level of evidence 4. Methods Analysis of cases through medical records and literature review. Results Four examples of unusual spontaneous CSF leaks of the skull base are presented. In each case, a CSF collection was contained behind the sinonasal mucosa of the sphenoid sinus, resembling a nasal polyp or mucocele on exam or imaging. In one case, the fluid collection was also associated with significant bone resorption and extravasation into the soft tissue of the infratemporal fossa. In each case, small defects of the ventral skull base (sphenoid bone) were the source of the CSF leaks. Successful treatment was achieved after transnasal endoscopic repair of the skull base defects using a combination of free abdominal fat grafts, free fascial grafts and pedicled nasoseptal flaps. Postoperatively, a ventriculoperitoneal shunt was placed if the intracranial pressure was elevated. Conclusions Spontaneous CSF leaks arising in the sphenoid sinus may not always present with overt CSF rhinorrhea but with a submucosal fluid collection (pseudomeningocele) that may mimic a mucocoele or nasal polyp. These bona fide pseudomeningoceles of the skull base may be associated with elevated intracranial pressure and can be managed using endoscopic endonasal surgery. PMID:22052361

    The endoscopic endonasal transsphenoidal approach (EEA) to treat sellar, parasellar, and suprasellar tumours continues to gain increased significance. Due to the close proximity of the sphenoid sinus to the carotid artery and the optic canal, it is very important for surgeons to know the anatomical features and variations of the sphenoid sinus as relevant to EEA. A prospective study of the sphenoid sinus morphology was carried out on the cranial tomographic (CT) scan images of 60 Nigerian adult patients. The CTs were reviewed regarding the different anatomical variations of the sphenoid sinus: dimensions, septation, and pattern of pneumatisation. There were 37 males and 23 females. The patients' ages ranged from 18 years to 85 years, with a mean of 47.2 years. There was a main single intersphenoid septum in most patients (95%). The insertion of the septum was usually to the right posteriorly (38%) and in the midline anterior (65%). Although there is usually a main septum, the septa present were multiple in 29 of the sinuses studied. There was no gender difference with respect to the attachment of the main sphenoid sinus septum. The sphenoid anterior, posterior, and transverse dimensions were not significantly dependent on age, but they were longer in males than in females. Sellar pneumatization was present in the majority of the patients (83%), with 4 patients having postsellar pneumatization (6.7%) and 3 patients having presellar pneumatization (5%). There were no cases with conchal pneumatization or lateral pneumatization of the greater wing of the sphenoid. The present study provides anatomical information about the sphenoid sinus dimensions morphology that is essential for avoiding complications in performing an endoscopic sphenoidotomy.

    Sphenoid sinus disease is particular not only for its clinical presentation, as well as their complications. Although rare, these may present as cranial nerve deficits, so it is important to have a high index of suspicion and be familiar with its diagnosis and management. Symptoms are often nonspecific, but the most common are headache, changes in visual acuity and diplopia due to dysfunction of one or more ocular motor nerves. The authors report a case of a 59 years-old male, who was referred to the ENT emergency department with frontal headaches for one week which had progressively worsened and were associated, since the last 12 hours, with diplopia caused by left third cranial nerve palsy. Neurologic examination was normal aside from the left third cranial nerve palsy. Anterior and posterior rhinoscopy excluded the presence of nasal masses and purulent rhinorrhea. The CT scan revealed a soft tissue component and erosion of the roof of the left sphenoid sinus. Patient was admitted for intravenous antibiotics and steroids treatment without any benefit after 48 hours. He was submitted to endoscopic sinus surgery with resolution of the symptoms 10 days after surgery. The authors present this case for its rarity focusing on the importance of differential diagnosis in patients with headaches and cranial nerves palsies.

    Introduction: The sphenoid sinus is often neglected because of its difficult access. The deep position of the sphenoid sinus hinders early diagnosis of pathologies in that location. Delayed diagnosis can cause serious complications due to proximity to many important structures. Objectives: The aim of this study is to demonstrate different pathologies which can affect the sphenoid sinus and elucidate the findings. Methods: Cases of isolated sphenoid sinus lesions encountered in the neurosurgical setting which had rare pathologies are discussed. Pathologies such as Langerhans cell histiocytosis, solitary plasmacytoma, chordoma, pituitary adenoma, leiomyosarcoma, fungal infection, and mucocele which appeared primarily in sphenoid sinus are discussed along with their imaging features and pathological findings. Conclusion: Multitude of different pathologies can occur in sphenoid sinus. Detailed preoperative imaging is very helpful, but transnasal biopsy and histological study are required often for definitive diagnosis. The possible advantages of early diagnosis before spread of pathology for prognosis cannot be overemphasized. PMID:28149092

    2013-01-01

    Background and Purpose Sphenoid bone fractures and sphenoid sinus fractures have a high morbidity due to its association with high-energy trauma. The purpose of this study is to describe individuals with traumatic injuries from different mechanisms and attempt to determine if there is any relationship between various isolated or combined fractures of facial skeleton and sphenoid bone and sphenoid sinus fractures. Methods We retrospectively studied hospital charts of all patients who reported to the trauma center at Hospital de San José with facial fractures from December 2009 to August 2011. All patients were evaluated by computed tomography scan and classified into low-, medium-, and high-energy trauma fractures, according to the classification described by Manson. Design This is a retrospective descriptive study. Results The study data were collected as part of retrospective analysis. A total of 250 patients reported to the trauma center of the study hospital with facial trauma. Thirty-eight patients were excluded. A total of 212 patients had facial fractures; 33 had a combination of sphenoid sinus and sphenoid bone fractures, and facial fractures were identified within this group (15.5%). Gender predilection was seen to favor males (77.3%) more than females (22.7%). The mean age of the patients was 37 years. Orbital fractures (78.8%) and maxillary fractures (57.5%) were found more commonly associated with sphenoid sinus and sphenoid bone fractures. Conclusions High-energy trauma is more frequently associated with sphenoid fractures when compared with medium- and low-energy trauma. There is a correlation between facial fractures and sphenoid sinus and sphenoid bone fractures. A more exhaustive multicentric case-control study with a larger sample and additional parameters will be essential to reach definite conclusions regarding the spectrum of fractures of the sphenoid bone associated with facial fractures.

    Paranasal sinus injuries by foreign bodies have a lower incidence compared with facial injuries. Among them, penetrating maxillofacial injuries to the sphenoid sinus and skull base remain rare. We report the case of a 41-year-old man who presented with, after a missile-related maxillofacial injury, a metallic foreign body enclosed within the sphenoid sinus with carotid-canal fracture. Angiographic evaluation showed a mass in the right internal carotid artery. The foreign object was successfully extracted through a transmaxillary sublabial approach with a good outcome. We discuss the extensive preoperative evaluation and interdisciplinary management of this unusual injury.

    Esthesioneuroblastoma (ENB) is a rare tumor derived from olfactory neuroepithelium. ENB in a site outside of where olfactory epithelium exists is exceedingly rare with only five cases of ENB isolated to the sphenoid sinuses described in the literature to date. To the best of our knowledge, a skin metastasis of ENB outside the head and neck region has not been reported. We present an unusual case of a 33-year-old male diagnosed with primary sphenoid sinus ENB, who underwent surgical resection of the tumor followed by chemoradiation. About 5 months later, the patient developed a dermal mass in the sternal region, clinically suspicious for metastasis. Fine needle aspiration (FNA) revealed a tumor with morphological features and immunophenotype consistent with the metastasis from patient's known primary sphenoid sinus ENB. Our case demonstrates that the skin may be a rare site of a metastatic ENB, and FNA is a cost-effective and reliable diagnostic method of a suspected cutaneous metastasis. PMID:23210016

    Sinonasal organized hematoma (SNOH) is rarely encountered in clinical practice. The disease demonstrates a high tendency for occurrence in East Asian individuals, and in the majority of cases, is located in the maxillary sinus. The current report presents the case of an 81-year-old female who developed a space-occupying lesion, which masqueraded as a skull base malignancy, following surgery for the treatment of isolated sphenoid sinus aspergilloma. Subsequent endoscopic endonasal surgery confirmed the diagnosis of an OH of the sphenoid sinus. The patient recovered from all neurological deficits within two months, with the exception of the loss of visual perception. Although SNOH presents a diagnostic challenge, when physicians possess knowledge of its typical imaging features, this facilitates the achievement of a correct diagnosis and the prescription of optimal treatment.

    Spontaneous meningoencephalocele (SME) of the sphenoid wing is a rare cause of cerebrospinal fluid (CSF) leakage. Surgical closure of the fistula is usually required. The approach taken depends on the location of the defect and the extension of the meningoencephalocele. The endoscopic transpterygoid approach may be useful. We prospectively analyzed the three cases of SME of the sphenoid wing with lateral sphenoid sinus extension treated endoscopically at Stanford over the last 3 years with regard to imaging findings, operative technique, and operative morbidity. In our three cases, the extent of pterygopalatine fossa (PPF) exposure undertaken, complete in one and partial in two, depended on the defect site. Follow-up ranged from 17 to 25 months. The fistula was completely closed in all three cases. Extant literature reports a 97% rate of successful closure (N = 65 of 67, with a mean follow-up of 25 months) and no major complications. Endoscopic transpterygoid repair is a useful, safe alternative to traditional approaches for repair of SME of the sphenoid wing. Its feasibility depends on the site of the defect, which can be identified by preoperative imaging. Larger PPF exposure and postoperative lumbar drainage of CSF can be useful and have a low risk of morbidity.

    A fungal ball consists of a dense conglomerate of fungal hyphae growing at the surface of the sinus mucosa without tissue infiltration. The maxillary sinus is by far the most commonly involved paranasal sinus cavity followed by the sphenoid sinus. The present study is a retrospective study of 25 consecutive cases treated during the last 10 years in the two hospitals be- longing to the Catholic University of Louvain (CHU Mont-Godinne and UCL Saint Luc). We report the symptomatology, the imaging and discuss the different surgical managements. We conclude that the clinician must have a high index of suspicion when dealing with a unilateral rhinosinusitis persisting despite a maximal and well conducted medical treatment. This is particularly so in elderly women when associated with facial pain and post nasal drip, particularly when the computed tomography shows an unilateral opacity of the sphenoid sinus with or without a sclerosis or an erosion of the bony walls, a polyp in the sphenoethmoidal recess or a hyperdensity mimicking a foreign body. An endonasal endoscopic sphenoidotomy is the treatment of choice in most cases, allowing good ventilation of the sinus and radical removal of all the fungal concretion. A biopsy of the sinus mucosa adjacent to fungal elements is of upmost important to confirm the non- invasiveness of the fungi within the tissue. Antifungal medication is not required in uncomplicated forms. All host factors producing some degree of immunosuppression must be corrected when present and must alert the clinician to rule out any forms of invasive disease.

    Ectopic acromegaly is a very rare clinical entity occurring in less than 1% of acromegalic patients. In most cases it is caused by GHRH or rarely GH-secreting neoplasms. Even rarer are ectopic pituitary adenomas located in the sphenoid sinus or nasopharynx that originate from pituitary remnants in the craniopharyngeal duct. This dissertation presents the difficulties in visualizing GH-secreting adenoma located in the sphenoid sinus. A 55-year-old man had somatic features of acromegaly for several years. MRI imaging revealed a slightly asymmetric pituitary gland (14 yen 4 mm) without focal lesions. Simultaneously, a spherical mass, 10 mm in diameter, corresponding with ectopic microadenoma was demonstrated on the upper wall of the sphenoid sinus. The serum GH level was 4.3 mg/l, IGF-1 = 615 mg/l, and a lack of GH suppression with oral glucose was proven. After preliminary treatment with a long-acting somatostatin analogue, transsphenoidal pituitary tumour removal was performed. Histopathological, electron microscopical and immunohistochemical analysis revealed densely granulated somatotropic pituitary adenoma: GH(+), PRL(-), ACTH(-), TSH(-), FSH(-), LH(-), MIB1 < 1%, SSTR3(+) and SSTR5(+). Post-surgical evaluation showed normal pituitary MRI scans, GH and IGF-1 levels 0.18 mug/l and 140 mg/l, respectively, as well as normal GH suppression with oral glucose. The careful analysis of possible pituitary embryonic malformations points out their significance for proper localization of extrapituitary adenomas.

    Sinus pneumatization is a complex variable process that begins in early life and continues for many years. We present a case of a 6-year-old boy with progressive headaches and neurologic symptoms suggestive of intracranial pathology. The presence of enhancing tissue within the sphenoid sinus created a diagnostic dilemma which leads to a transsphenoidal biopsy. Knowledge of imaging characteristics associated with incomplete pneumatization can help differentiate it from more ominous skull base pathology and prevent unnecessary testing. We describe four-year imaging follow-up in a patient with incomplete pneumatization of the sphenoid sinus presenting as an enhancing mass lesion with subsequent follow-up imaging demonstrating gradual regression and increased aeration of the sphenoid sinus.

    Statement of the Problem The sphenoid sinus is a common target of paranasal surgery. Functional endoscopic sinus surgery is likely to endanger the anatomic variations of vital structures adjacent to the sphenoid sinus. Purpose The aim of this study was to determine the variations of sphenoid sinus and the related structures by using cone-beam computed tomography (CBCT). Materials and Method In this descriptive-analytic study, CBCT images of 103 patients aged above 20-years were selected (206 sides). Degree of pneumatization of sphenoid sinus, pneumatization of the anterior clinoid process, pterygoid process, protrusion of optic canal, vidian canal, and foramen rotundum, as well as prevalence of sinus septa were recorded. Examinations were performed using On-Demand software (Version 1); data were analyzed by using chi-square test. Results There was a statistically significant correlation between the pterygoid pneumatization and vidian canal protrusion (p< 0.001), and foramen rotundum protrusion (p< 0.001). The optic canal protrusion was found to be significantly associated with the anterior clinoid pneumatization and pterygoid process (p< 0.001). Statistically significant relationship was also observed between the carotid canal protrusion and pterygoid process pneumatization (p< 0.001). Conclusion The anatomical variations of the sphenoid sinus tend to give rise to a complexity of symptoms and potentially serious complications. This variability necessitates a comprehensive understanding of the regional sphenoid sinus anatomy by a detailed CBCT sinus examination. PMID:26966706

    Ectopic pituitary adenomas (EPAs) are rare lesions. The purpose of this study was to describe the CT and MRI features of sphenoid sinus EPAs. Eight patients with histology-proven EPAs in the sphenoid sinus, all of whom underwent CT and MRI, were reviewed retrospectively. The following imaging features were analysed: (i) size, (ii) margin, (iii) CT attenuation characteristics and (iv) MRI signal intensity. In addition, the involvement of adjacent structures and the time–intensity curve (TIC) of dynamic contrast-enhanced (DCE) MRI were analysed. All EPAs had well-defined margins and showed no relationship to the intrasellar pituitary gland. The mean size was 28 mm (range, 20–46 mm). On non-enhanced CT, the lesions appeared isodense to grey matter in 7 (88%) patients and hypodense in 1 (12%) patient. Only two patients underwent post-contrast CT, and they showed moderate enhancement. On T1 weighted images, EPAs appeared isointense in 6 (75%) patients and hypointense in 2 (25%). On T2 weighted images, the lesions appeared hyperintense in 2 (25%) patients and isointense in 6 (75%). EPAs showed mild to moderate heterogeneous contrast enhancement and exhibited a cribriform-like appearance. Two patients underwent DCE MRI; the TIC showed a rapidly enhancing and slow washout pattern. The following features were also seen: an empty sella, bone changes and involvement of the cavernous sinus (5 patients; 62.5%). In conclusion, a high index of suspicion for EPA and a familiarity with the imaging findings may help to diagnose this rare entity accurately. PMID:19651706

    In this study, electrolyte (sodium (Na), chlorine (Cl), and magnesium (Mg)) and total protein (TP) concentrations and volume of liquid in the sphenoid sinus were examined to determine their usefulness to elucidate whether drowning occurred in freshwater or seawater. We examined 68 cases (seawater drowning group: 27 cases, freshwater drowning group: 21 cases, non-drowning group: 20 cases). There was a significant difference in Na, Cl, Mg, and TP concentrations of liquid in the sphenoid sinus among the three groups (seawater drowning, freshwater drowning, and non-drowning groups). To distinguish freshwater drowning from seawater drowning, Na, Cl, and Mg concentrations of liquid in the sphenoid sinus might serve as useful indicators.

The characteristic symptoms and signs have been described, and the diagnostic neuroradiologic features have been demonstrated. The condition is not a benign one, as is demonstrated by total blindness which occurred in one patient (Case 2). A high index of suspicion for this condition with early referral for neuroradiologic diagnosis leads to proper management and treatment which is usually successful.

    BACKGROUND:: The sellar wall of the sphenoid sinus and its recesses have been previously studied, but their intracranial relationships to the diaphragma sellae, tuberculum, clinoid segment of the internal carotid artery, chiasmatic sulcus, and middle clinoid process need further definition. OBJECTIVE:: To describe these intra and extracranial relationships of the recesses in the anterior sellar wall. METHODS:: The middle clinoid was studied in 132 parasellar areas of dry skulls. Thirty-eight parasellar areas of formalin-fixed/silicone-colored specimens were dissected. After transsphenoidal endoscopic exposure, the optic, carotid, and sellar prominences; lateral opticocarotid and tuberculum recesses; and caroticosellar and medial opticocarotid points were identified. High-speed drills opened 1 mm perforations at these points to allow study of intracranial relationships. RESULTS:: Two recesses and two junction points can be recognized in the sphenoid sinus: lateral opticocarotid and tuberculum recesses and medial opticocarotid and caroticosellar points. The lateral opticocarotid recess corresponds to the optic strut base, and the clinoid segment of the internal carotid artery is located medially. The diaphragma sellae attachment is at the level of the tuberculum recess, which in 50% of cases corresponds to the tuberculum. A middle clinoid in base or height greater than 1.5 mm is present in 21.1% and a caroticoclinoid ring in 3%. The middle clinoid is 1 mm inferior and lateral to the caroticosellar point and 4.7 mm inferior to the medial opticocarotid point. CONCLUSION:: An understanding of the intra and extracranial relationships of the recesses of the sphenoid sinus will aid in accurately directing transsphenoidal approaches.

    Introduction Isolated disease of the sphenoid is rare and has often been overlooked due to its remote location and difficult access. Objective A retrospective study of the main causes of isolated sphenoid sinus diseases with discussion of the most appropriate methods of diagnosis and treatment. Methods A total of 46 cases of isolated sphenoid disease treated between January 2008 and December 2013 were evaluated by objective ear, nose, and throat examination and video endoscopy, computed tomography of the paranasal sinuses, and, in some cases, magnetic resonance imaging. In each case, we decided between drug and/or endoscopic treatment. Results We identified 12 cases of isolated sphenoiditis (26.1%), 3 cases of fungal sphenoiditis (6.5%), 3 cases of sphenochoanal polyps (6.5%), 22 cases of mucocele (47.8%), 2 cases of cerebrospinal fluid leak (4.3%), and 1 case each of meningoencephalocele (2.1%), inverted papilloma (2.1%), fibrous dysplasia (2.1%), and squamous cell carcinoma (2.1%). Conclusion A prevalence of inflammatory and infectious diseases was found, and endoscopic surgery for the sphenoid sinus approach is effective in treating various diseases of the isolated sphenoid, whether complicated or not.

    A case report is presented of a 35-year-old woman who developed a progressive right optic neuropathy while surfacing from a series of four recreational dives on the Great Barrier Reef, Queensland, Australia. The patient reported severe sudden onset blurred vision in the right eye associated with a mild headache and epistaxis on surfacing from diving. The patient had her first medical review the day after returning from her trip. At this time visual acuity in the right eye was 20/80, with left eye 20/20. There was a relative afferent pupillary defect in the right eye. A high-resolution computed tomography scan showed fluid in the right sphenoid sinus. Computed perimetry revealed patchy visual field loss in the right eye. The provisional diagnosis of sphenoidal sinus barotrauma-induced optic neuropathy was made. Over 10 days of observation, the visual acuity returned to 20/20 in the right eye and visual field changes resolved. This case highlights a very unusual cause of visual loss associated with diving.

    Although mucocele is a benign lesion, its unavoidable expansions may result in irreversible damages in adjacent organs. In spheno-ethmoid mucoceles which are extremely rare, this condition may cause more severe problems. Central diabetes insipidus, developed secondary to sphenoid sinus mucocele, was detected in a 54-year-old male patient, who underwent endoscopic sinus surgery 2 times due to nasal polyposis. Endoscopic sphenoid mucocele marsupialization was performed to the patient, but despite partial regression in the 1-year follow up, complete recovery was not observed.

    We have investigated the usefulness of elemental analysis by energy-dispersive X-ray spectroscopy (EDX) in the examination of free liquid from the sphenoid sinus of drowning victims. We detected both chlorine and bromine in liquid taken from the sphenoid sinus of seawater drowning victims. Because these elements were below the quantification limit in freshwater cases, we could easily distinguish seawater from freshwater drowning cases. Detection of these elements from the liquid in the sphenoid sinuses of drowning victims may be useful as a supportive measure for seawater drowning.

    Objective To describe the clinical features of invagination of the sphenoid sinus mucosa (ISM) and compare them with other similar cases using a visual analog scale (VAS) to assess the various nasal symptoms and to discuss its clinical significance and means of prevention. Study Design Retrospective chart review at a tertiary referral center. Methods Between 2010 and 2015, 8 patients who had undergone EETSA surgery displayed postoperative ISM. The comparison group consisted of 147 patients who underwent the same surgical procedures and were diagnosed with the same diseases. Pre- or postoperative paranasal sinus computed tomography (PNS CT) and VAS were performed and subsequently analyzed. Results The clinical features of ISM of the sphenoid sinus showed sellar floor invagination and regenerated inverted ingrowing sphenoid mucosa on endoscopic imaging. PNS CT also showed a bony defect and invaginated air densities at the sellar turcica. Pre- and postoperative VAS scores revealed that the ISM group had much less of an improvement in headaches after surgery than that of the comparison group (p = 0.049). Conclusion ISM may occur because of a change in pressure, sphenoid mucosal status, or arachnoid membrane status. Moreover, ISM is related to improvements in headaches. Therefore, EETSA patients should avoid activities that cause rapid pressure changes during the healing process. In addition, sellar reconstruction that is resistant to physical pressure changes should be mandated despite the absence of an intraoperative CSF leak. PMID:27622454

    The transsphenoidal approach to the sellar region has been introduced more than a 100 years ago. It is the accepted standard operative corridor to pathologies of the pituitary gland and surrounding structures. There are anatomical landmarks within the sphenoid sinus that are used for orientation directing to the sella floor or the cavernous sinus. Yet, little data can be found on the consistency of these landmarks. It is the aim of this study to evaluate the reliability of these anatomical landmarks for the surgeon's orientation. A total of 245 computed tomography (CT) volume data sets of the cranium performed according to a standardized protocol were analyzed for study purposes. CT scans of the cranium of 125 patients admitted to the emergency room of our hospital receiving a trauma spiral according to the local protocol were employed as a control group when no pathology in the sellar region was observed. In addition, preoperative CT scans of a group of 120 patients diagnosed with pituitary adenomas between 2009 and 2013 were analyzed. Image analysis of the anatomical landmarks included the minimal intercarotid distance (ICD), diameter of the sphenoid sinus (DSS), direction of the septum sinuum sphenoidalium (SSS), and the distance between vomer and clivus (VCD). The overall mean ICD was 16.2 mm, with patients suffering from adenomas showing a mean ICD of 15.8 mm compared with an average 16.5 mm in the control group. DSS was equal for both groups (adenoma group: mean 31.5 mm; controls: mean 31.3 mm). Mean VCD was 27.9 mm in patients with pituitary adenomas compared with 26.7 mm in controls. A septum of the sphenoid sinus located in the midline was found in overall 23 % only. SSS was directed into the bony shield of the internal carotid artery in 28 % of underlying tumors and in 37 % of the control group. This is the first detailed description of landmarks of the sphenoid sinus based on a large radiologic-anatomical analysis of CT scans yielding a wide

    Background: Sphenoid sinus fungal balls (SSFB) are rare entities that can result in serious orbital and intracranial complications. There are few published reports of complications that result from SSFB. Objective: To review the incidence of skull base erosion and orbital or intracranial complications in patients who present with SSFB. Methods: A retrospective review was performed of all the patients with SSFB who were treated at the Massachusetts Eye and Ear Infirmary from 2006 to 2014. Presenting clinical data, radiology, operative reports, pathology, and postoperative course were reviewed. Results: Forty-three patients with SSFB were identified. Demographic data were compared between patients with (39.5%) and those without (61.5%) skull base erosion. Two patients underwent emergent surgery for acute complications of SSFB (one patient with blindness, one patient who had a seizure). Both patients with acute complications had evidence of skull base erosion, whereas no patients with an intact skull base developed an orbital or intracranial complication (p = 0.15). All the patients were surgically managed via an endoscopic approach. Conclusion: SSFBs are rare but may cause significant skull base erosion and potentially severe orbital and intracranial complications if not treated appropriately. Endoscopic sphenoidotomy is effective in treating SSFB and should be performed emergently in patients who presented with associated complications.

    Background An ectopic pituitary adenoma presenting as a clival or sphenoid mass is a rare clinical occurrence that may mislead the clinician and result in unnecessary interventions or potential medicolegal consequences. Here, we present one of the largest multi-institutional case series and review the literature with an emphasis on radiological findings and critical preoperative workup. Methods Retrospective chart review. Results Nine patients were identified with ectopic pituitary adenomas of the sphenoid or clivus. There were four females and five males. Median age was 60 years old (range, 36-73 years). The most common presenting symptom was headache (56%). Five (56%) patients presented with a mass arising from the clivus while four (44%) presented with a mass in the sphenoid. Six (67%) patients demonstrated biochemical evidence of hypersecretion on full endocrinology panel. All masses showed evidence of enhancement with gadolinium with a propensity for adjacent bone involvement. Lesions also had a predilection for growth toward the cavernous sinus, carotid artery, or sellar floor. Surgical intervention was performed in eight patients (89%). In eight patients (89%), tumors demonstrated immunoreactivity to prolactin. Conclusions Pituitary adenomas can rarely present as an isolated sphenoid or clival mass. Lesions displayed similar magnetic resonance imaging findings with an erosive growth pattern toward the sellar floor, cavernous sinus, or adjacent carotid artery. Patients with clival or parasellar lesions with comparable features should have a preoperative workup which includes prolactin level and alert the physician to consider an ectopic pituitary adenoma in the differential to prevent unnecessary surgery and potential complications.

    An aneurysmal bone cyst (ABC) typically involves the long bones of the extremities, thorax, pelvis, or vertebrae. Skull base involvement is rare. We describe the case of a 9-year-old girl with ABC of the skull base. The patient had presented with nasal obstruction and headache over a period of approximately 8 months. The patient had no history of trauma or surgery. Physical and neurological examination findings normal. Magnetic resonance imaging (MRI) showed a multicystic lesion arising from the sphenoid sinus and extending into ethmoid sinus, superior nasal cavity and medial walls of the orbit. The lesion contained thin internal septations that revealed high signal characteristics on all sequences. The lesion was resected via an extended frontal approach without any complications. Histological evaluation confirmed that the lesion was an ABC. The patient did not receive postoperative radiotherapy. No recurrence was observed after 22 months. ABC should be considered in the differential diagnosis of bone neoplasms in this region.

    Introduction Hypophysitis is a chronic inflammation of the pituitary gland of complex and still incompletely defined pathogenesis. It belongs to the group of non-hormone-secreting sellar masses, sharing with them comparable clinical presentation and radiographic appearance. Objectives Describe the case of immunoglobulin G4 (IgG4)-related hypophysitis presenting as a mass in the sphenoid sinus. Resumed Report A 40-year-old Brazilian man had a diagnosis of central diabetes insipidus since 2001 associated with pituitary insufficiency. Pituitary magnetic resonance imaging revealed a centered pituitary stalk with focal nodular thickening and the presence of heterogeneous materials inside the sphenoid sinus. The patient was treated with testosterone replacement therapy. Laboratory results revealed increased IgG4 serum. Conclusion IgG4-related hypophysitis should be considered in patients with pituitary insufficiency associated with sellar mass and/or thickened pituitary stalk. IgG4 serum measurement for early diagnosis of IgG4-related hypophysitis should be performed.

    2016-01-01

    Chronic sphenoid rhinosinusitis is a spectrum of inflammatory diseases in isolated sphenoid sinus which may persist over a period of 12 weeks. It is a different entity from other types of rhinosinusitis because clinical presentations include headache, visual loss or diplopia, and patients may or may not have nasal obstruction or nasal discharge. Nasal endoscopic examination is useful, and computed tomography is mandatory. The disease requires comprehensive knowledge and appropriate imaging technique for diagnosis. To treat patients with chronic sphenoid rhinosinusitis, surgical treatment with endoscopic transnasal sphenoidotomy is often required. As there are no recent updated reviews of chronic sphenoid rhinosinusitis, in this article, we review the anatomy of the sphenoid sinus and its clinical relationship with the clinical signs and symptoms of the disease, the imaging findings of each diagnosis and the comprehensive surgical techniques.

    Sphenoid wing meningiomas (SWMs) typically are histologically benign, insidious lesions, but the propensity of these tumors for local invasion makes disease control very challenging. In this review, we assess whether the degree of resection and extent of cavernous sinus invasion affects morbidity, mortality, and recurrence in patients with SWM. A comprehensive search of the English-language literature was performed. Patients were stratified according to extent of resection and extent of cavernous sinus invasion, and tumor recurrence rate, morbidity, and mortality were analyzed. A total of 23 studies and 131 patients were included. Overall recurrence and surgical mortality rate were 11% and 2%, respectively (average follow-up = 65 months). Cranial nerve III palsy was significantly associated with incompletely versus completely resected SWMs (7 to 0%) as well as meningiomas with cavernous sinus invasion versus no sinus invasion (14 vs. 0%). No significant difference in tumor recurrence rate was noted between these groups. In conclusion, complete excision of SWMs is always recommended whenever possible, but surgeons should acknowledge that there is nonetheless a chance of recurrence and should weigh this against the risk of causing cranial nerve injuries.

    Isolated extramedullary relapse of chronic myelogenous leukemia (CML) after allogeneic stem cell transplant is rare. There is a case report of a child who developed a granulocytic sarcoma of the maxillary and sphenoid sinuses and lumbosacral spinal cord mass 18 months after allogeneic bone marrow transplant for CML. He was presented with per orbital edema and neurological deficit of lower extremities and a mass lesion was found on spinal cord imaging. No evidence of hematologic relapse was identified at that time by bone marrow histology or cytogenetic. The patient died 1 month later with a picture of pneumonia, left ventricular dysfunction and a cardiopulmonary arrest on a presumed underlying sepsis with infectious etiology. Granulocytic sarcoma should be considered in the differential diagnosis of mass lesions presenting after allogeneic bone marrow transplantation for CML, even if there is no evidence of bone marrow involvement.

    A case of radionecrosis of sphenoid and temporal bones is reported. The patient received a combination of surgery, radiotherapy, and chemotherapy for his left maxillary sinus carcinoma. After the combined therapy, necrosis accompanying inflammation developed in the maxillary and temporal regions. Excision of the necrotic tissues was done, and the left ascending ramus of the mandible was resected because of persistent tumor mass at the left infratemporal fossa. Although the excision wound of the maxilla healed by epithelialization, an area of nonvital bone remained exposed in the temporal region, where progressive osteonecrosis with infection led to breakdown of the skin. The necrotic bones of the zygomatic arch and the sphenotemporal sutural region became visible through the skin defect, and computerized tomography scan revealed bone necrosis involving the inferolateral area and the base of the skull. Excision of the necrotic bone and reconstruction with sternocleidomastoid myocutaneous flap were performed.

    The aim of this study was to analyze the bacterial flora in the nasal cavity and sphenoid sinus and evaluate the sensitivity of these bacteria to antibiotics that can be used to prevent postoperative meningitis. Bacteria of the preoperative nasal cavity and intraoperative sphenoid sinus mucosa were cultured and analyzed in 40 patients (20 men and 20 women; mean age, 52.2 years) who underwent endoscopic transsphenoidal surgery. The sensitivity of these bacteria to cephalosporin, a representative prophylactic antibiotic, was examined. Staphylococcus epidermidis was the most frequently detected species in both spaces; 24 (38.7%) of 62 isolates in the nasal cavity and 26 (37.1%) of 70 isolates in the sphenoid sinus. In contrast, Corynebacterium species were found mainly in the nasal cavity, and anaerobic bacteria were found only in the sphenoid sinus. Bacteria that were resistant to cephalosporin were found in the nasal cavity in 3.2% of patients and in the sphenoid sinus in 20% of patients. In conclusion, the composition of bacterial flora, including bacteria that are resistant to prophylactic antibiotics, differs between the nasal cavity and the sphenoid sinus. PMID:25446386

    The aim of this study is to assess the pneumatization of the paranasal sinuses (PNS) and other parts of temporal bone such as mastoid air cells and to investigate if there was any association between the aeration of these structures among the three major ethnic groups in Malaysia (Malay, Chinese, Indian) as this would be representative of Asia. A retrospective review of 150 computed tomography (CT) scans of PNS and temporal bones was done and analysed. The pneumatization of each area was obtained and compared using statistical analysis. Patients with a history of previous medical or surgical problems in the intended areas were excluded from the study. The pneumatization of the mastoid air cells and other temporal bone parts were noted to be symmetrical in more than 75 %. There was a positive correlation between the pneumatization of mastoid air cells and that of the sphenoid sinus. The prevalence of Agger nasi, Haller's and Onodi cells was observed to be significantly higher in the Chinese group. Preoperative assessment of the temporal bone and PNS with CT scan may be helpful in the evaluation of their anatomical landmark and decrease the possibility of surgical complications related to 3D structures.

    In recent years, the transsphenoidal approach has been extensively used surgically to treat parasellar, suprasellar, clival, and even petrous lesions. Extended pneumatization of the sphenoid sinus (SS) is considered an indispensable element for the extended transsphenoidal (ETS) approach. Because most anatomical studies of the ETS approach use Caucasian subjects, the present study aims to clarify the pneumatic extension types in Chinese individuals as well as any differences from those in Caucasians and analyze these differences with respect to the application of the ETS approach. A total of 200 computed tomography (CT) images of SSs and 18 adult cadaveric heads were selected for observation and measurement. The conchal, presellar, and sellar types comprised 6, 28.5, and 65.5% of subjects, respectively; according to the extra extension, the prevalence of the lateral, clival, lesser wing, and combined extension sinus types was 11.4, 21.4, 0.8, and 48.1% of subjects, respectively. The percentages of pneumatization of the anterior and posterior clinoid processes, pterygoid process, and optic strut were 5.0, 1.0, 22.3, and 7.0%, respectively. Onodi cells were observed in 61.1% of the sides of the cadaveric heads, including 30.6% with good pneumatization with identifiable optical or ICA bulges. These features were related to poor lateral and clival gasification in Chinese compared with Caucasians, which might make extended surgery more dangerous. However, the anterior pneumatization, especially the higher presentation of Onodi cells, ensures that the anterior ETS approach can be performed safely in Chinese patients. In general, measurements showing smaller sinus volumes and thicker bones with identifiable bone landmarks that are hard to find compared with those in Caucasians suggest increased surgical risks in the Chinese population. In this situation, carefully analysis of presurgical CT and magnetic resonance imaging scans is important. Furthermore, in the ETS

    from 16 to 76 years, and there were 15 women and 4 men. The mean and median diameters of the resected sphenoid masses were 13.9 and 8 mm, respectively, with a range of 3-55 mm. Seven were microadenomas (< 1 cm). Fifteen of the 19 cases reported serum ACTH and morning cortisol levels, the means of which were 106.7 pg/ml and 32.5 μg/dl, respectively. Gross-total tumor resection was achieved in all patients except one, and in all of them durable hormonal remission of Cushing syndrome was achieved (mean follow-up time 20 months). Ectopic pituitary adenomas are rare but important causes of Cushing syndrome and related endocrinopathies, particularly because of the rapid onset and severity of symptoms with atypical presentation. Ectopic pituitary adenomas, especially those in the nasal cavity, nasopharynx, or paranasal sinuses, are easily misidentified. Any patient presenting with signs and symptoms of Cushing syndrome without any obvious pituitary adenoma or other sources of hypercortisolemia should be thoroughly screened for an ectopic adenoma. However, as with the case presented here, the coincident existence of a sellar mass should not preclude the possibility of an ectopic source. There should be a high degree of clinical suspicion for any mass in the general area surrounding the sella when evaluating Cushing syndrome.

  3. Ectopic acromegaly due to a GH-secreting pituitary adenoma in the sphenoid sinus: a case report and review of the literature

    PubMed Central

    2013-01-01

    Background In more than 98% of cases, acromegaly is due to a GH-secreting pituitary adenoma. The term “ectopic acromegaly” includes neuroendocrine tumors secreting GH releasing hormone (GHRH), usually located in the lungs, thymus and endocrine pancreas. Considerably less frequent are cases of ectopic acromegaly due to GH-secreting tumors located out of the pituitary fossa; except for one isolated case of a well-documented GH-secreting lymphoma, the majority of these lesions are located in the sphenoid sinus. Case presentation We present the case of a 45 year old woman with acromegaly whose MRI showed an empty sella without evidence of a pituitary adenoma but revealed a large mass within the sphenoid sinus. She underwent transsphenoidal surgery and the excised sphenoid sinus mass, proved to be a GH-secreting adenoma; the sellar floor was intact and no other lesions were found in the pituitary fossa. She required postoperative treatment with somatostatin analogs and cabergoline for clinical and biochemical control. Conclusions This case highlights the importance of carefully evaluating the structures surrounding the sellar area when a pituitary adenoma is not found with currently available imaging techniques. The finding of an intact sellar floor and duramater lead us to conclude that the patient’s tumor originated de novo from embryological pituitary remnants. Upon a careful review of the literature and a critical evaluation of our case we found neither clinical nor biochemical features that would distinguish an ectopic from the more common eutopically located somatotrophinoma.

    The authors report a case of invasive aspergillosis of a sphenoid sinus mucocele revealed in a patient with diabetes in Djibouti by homolateral palsy of the 3rd, 4th, 5th and 6th nerves. This rare condition occurs preferentially in immunodeficient subjects. Because of its clinical polymorphism, its diagnosis is difficult and is often not made until complications develop. Endonasal surgery with anatomopathological and mycological examination is both a diagnostic and therapeutic procedure. It must be performed early, to avoid functional or even life-threatening complications.

    BACKGROUND AND STUDY OBJECT We report an unusual case of a benign lateral sphenoid wing meningioma that presented with, and was masked by, an acute intracerebral hemorrhage. CASE REPORT A 68-year-old woman was admitted after sudden onset of coma. Computed tomography (CT) revealed an intracerebral hemorrhage, without any underlying vascular pathology on CT angiography. During the surgery, we found a lateral sphenoid wing meningioma with intratumoral bleeding that extended into the surrounding brain parenchyma. RESULTS We removed the hematoma and resected the tumor completely in the same session. The histopathological classification of the tumor was a WHO grade I meningothelial meningioma. The patient recovered very well after surgery, without significant neurological sequelae. CONCLUSIONS: Having reviewed the relevant references from the medical literature, we consider this event as an extremely rare presentation of a benign sphenoid wing meningioma in a patient without any predisposing medical factors. The possible mechanisms of bleeding from this tumor type are discussed. PMID:27127413

    Ectopic sphenoid sinus pituitary adenoma (ESSPA) may arise from a remnant of Rathke's pouch. These tumors are frequently misdiagnosed as other neuroendocrine or epithelial neoplasms which may develop in this site (olfactory neuroblastoma, neuroendocrine carcinoma, sinonasal undifferentiated carcinoma, paraganglioma, melanoma). Thirty-two patients with ESSPA identified in patients with normal pituitary glands (intact sella turcica) were retrospectively retrieved from the consultation files of the authors' institutions. Clinical records were reviewed with follow-up obtained. An immunohistochemical panel was performed on available material. Sixteen males and 16 females, aged 2-84 years (mean, 57.1 years), presented with chronic sinusitis, headache, obstructive symptoms, and visual field defects, although several were asymptomatic (n = 6). By definition, the tumors were centered within the sphenoid sinus and demonstrated, by imaging studies or intraoperative examination, a normal sella turcica without a concurrent pituitary adenoma. A subset of tumors showed extension into the nasal cavity (n = 5) or nasopharynx (n = 9). Mean tumor size was 3.4 cm. The majority of tumors were beneath an intact respiratory epithelium (n = 22), arranged in many different patterns (solid, packets, organoid, pseudorosette-rosette, pseudopapillary, single file, glandular, trabecular, insular). Bone involvement was frequently seen (n = 21). Secretions were present (n = 16). Necrosis was noted in 8 tumors. The tumors showed a variable cellularity, with polygonal, plasmacytoid, granular, and oncocytic tumor cells. Severe pleomorphism was uncommon (n = 5). A delicate, salt-and-pepper chromatin distribution was seen. In addition, there were intranuclear cytoplasmic inclusions (n = 25) and multinucleated tumor cells (n = 18). Mitotic figures were infrequent, with a mean of 1 per 10 HPFs and a <1% proliferation index (Ki-67). There was a vascularized to sclerotic or calcified

In each lateral teleradiography, the dimensions of the inferior and superior pharyngeal airway space, TB-PhW1 [the point between the posterior aspect of the tongue to the dorsal pharyngeal wall (oropharynx) (TB) and the point on the dorsal pharyngeal wall closest to TB (PhW1)] and UP-PhW2 [and the point between the posterior aspect of the soft palate to the dorsal pharyngeal wall (nasopharynx) (UP) (PhW2)] measurements were evaluated, as well as the dimensions of the frontal and sphenoid sinuses. The differences between the two operative times were evaluated by Student's t-test. Results All measurements showed excellent reproducibility for the intraclass correlation coefficient (ICC > 0.9; p < 0.0001). There was an increase in the measurements TB-PhW1 and UP-PhW2 and a decrease in the dimensions of the frontal and sphenoid sinuses after orthognathic surgery. Conclusions The morphology of the superior and inferior pharyngeal airway space and frontal and sphenoid sinuses changes after 6 months of maxillomandibular advancement counterclockwise rotation for class II anterior open bite malocclusion.

    A 42 year old male presents with worsening pain and an increase in thick chronic drainage of the left sinus. Image studies show complete opacification of the left frontal sinus, left sphenoid sinus, and the left maxillary sinus. The patient was taken to the operating room and tissue for microscopic evaluation was obtained. The microscopic findings were classic for allergic fungal sinusitis: areas of alternating mucinous material and inflammatory cell debris and abundant Charcot-Leyden crystals. Cultures were performed and the patient began steroid therapy and desensitization therapy.

    Esthesioneuroblastoma (ENB), or olfactory neuroblastoma, is a rare malignant neoplasm arising from the olfactory neuroepithelium. Typically, ENBs are found in the olfactory cleft with extension to the ethmoid sinuses or anterior skull base. Here we report a case of ENB located in the sphenoid sinus, which had been considered as an ectopic ENB. However, endoscopic resection revealed the continuity of the tumor with the hindmost olfactory filament. The present case suggests that an ENB in the sphenoid sinus was not ectopic, but arose from the normal olfactory neuroepithelium. This continuity of the ENB with this filament indicated that the tumor was not ectopic, and that there was possible tumor invasion into the olfactory neuroepithelium in the cribriform niche. Therefore, pathological examination of the olfactory neuroepithelium in the cribriform niche may be necessary in case of sphenoid ENBs.

    A 32 year Libyan male presented with the complaints of headache and diplopia. He was diagnosed with a cavernous sinus meningioma on the basis of MRI findings but no initial biopsy was taken. Depending on the radiologic diagnosis the patient was treated with gamma knife surgery twice, abroad. During follow up he developed left ear deafness and left cervical lymph adenopathy. An ENT evaluation with biopsy from the nasopharynx and cervical lymph node was taken. The histopathologic diagnosis of the resected tumour showed a nasopharyngeal carcinoma with cervical lymph node metastasis (poorly differentiated lympho-epithelial carcinoma). The cavernous sinus tumour which was initially treated as a meningioma was in fact metastasis from the nasopharyngeal carcinoma, making this an interesting and rare occurrence.

    We report a very unusual presentation of giant cell tumor probably originated on the greater wing of the sphenoid and show a review about the knowledge and the treatment of the lesion in this rare localization. We treated a 48-year-old man with a giant cell tumor of the infratemporal fossa. He presented with a right-side hearing loss and facial pain. The tumor was resected by means of a subtemporal-preauricular approach, and after 12 months of follow-up, the patient is free of recurrence. Giant cell tumors of the skull base are an extremely rare neoplasm, and there is not much information on the literature about the treatment and the prognostic. Wide resection ought to be made, and at the follow-up, the clinician must try to diagnose not only local recurrence but also the possibility of distant metastases to the lung.

    BACKGROUND AND AIM: Preauricular sinus abscess is a common congenital external ear disease. This abscess is usually misdiagnosed because it is commonly overlooked during physical examination. In Nigeria, the prevalence was 9.3% in Ilorin, north central Nigeria This study is to determine the distribution and clinical presentation of the preauricular sinus abscess in Ekiti, south west Nigeria. MATERIALS AND METHODS: This is a prospective hospital based study of all patients with diagnosis of preauricular sinus abscess seen in our clinic carried out between April 2008 to March 2010. Detailed clinical history, administered interviewer’s assisted questionnaires full examination and. Data obtained were collated and analysed. RESULTS: Preauricular sinus were noticed in 184 (4.4%) out of 4170 patients seen during the study period. Preauricular sinus abscess were noticed in 21 (11.4%) of the preauricular sinuses especially in children. Unilateral preauricular sinus abscess accounted for 90.5%. Common presenting complaints were preauricular swelling (81.0%), 90.5% with recurrent earaches, 76.2% with ear discharges. All patients had antibiotic / analgesic while 17 out of 21 (81.0%) had surgical excisions. CONCLUSION: Preauricular sinus abscess were noticed among 11.4% of the preauricular sinuses especially in children, unilateral preauricular sinus abscess accounted for 90.5%. Common complaints were otorrhoea, earaches, and swelling and they were mostly managed surgically. PMID:24711764

    Sixty six year old male with history of heart failure was admitted for dysphagia, weight loss. CT scan chest revealed diffuse oesophageal wall thickening. Upper endoscopy, oesophagogram confirmed diagnosis of achalasia. TTE revealed severely reduced biventricular systolic function with LVEF 10%; PASP 75-80 mmHg. Parasternal long views showed dilated coronary sinus with a visible, mobile 2.0 cm thrombus. Pro-thrombotic workup was negative. Coronary sinus thrombosis has been identified as a rare complication to invasive cardiac procedures causing damage to coronary sinus endothelium and in hypercoagulable states.Typically acute thrombosis presents with chest pain, dynamic ECG changes, but chronic development does not present with ischaemic signs due to formation of efficient collateral circulation. We present a case report of stable primary coronary sinus thrombus incidentally diagnosed, secondary to chronic venous stasis in coronary circulation. Currently, there are no guidelines to assist physicians in long term management of such patients and thus warrants further investigations.

    1999-05-01

    A 76-year-old man insidiously developed diffuse neurological symptoms: cognitive decline, dysphagia, dysphasia and mental disturbance. Computed tomography of the cranium revealed widespread bilateral brain edema and symmetrical bilateral sphenoid wing hyperostosis. Adjacent to the hyperostosis that resembled skull base meningiomas, two separate parenchymatous temporal lobe lesions enhancing with contrast medium were observed. The patient had earlier been diagnosed to have prostatic carcinoma. Dexamethasone therapy resulted in discontinuation of the neurological symptoms. The diagnosis of metastasized adenocarcinoma of the prostate was confirmed histologically on autopsy after a sudden death from pneumonia. Intracranial metastases of prostate cancer may have a predilection site at the sphenoid wing, and can mimic a skull base meningioma. Intracranial spread of prostatic adenocarcinoma should be considered in elderly men as a treatable cause of gradual neurological deterioration, especially if cranial malignancy or hyperostosis is found.

    Sinonasal undifferentiated carcinoma is an extremely rare malignancy of the paranasal sinuses and nasal cavity. It is of unknown etiology, and occurs more commonly in the elderly men, with a routinely shown aggressive behavior and poor prognosis for survival. Radiographically, it looks like severe osteomyelitis. Histopathologic study is essential to confirm diagnosis, and the undifferentiated histologic appearance often necessitates immunohistochemical studies for differentiation from other high-grade neoplasms. We present an 83-year-old man complaining of pain and unilateral swelling on the left side of the face due to a rare malignant tumor of maxillary sinus origin, a sinonasal undifferentiated carcinoma. He underwent hemimaxillectomy and radiotherapy, but refused chemotherapy. Maxillary sinus malignancy may be presented with unspecific symptoms mimicking sinusitis or dental pain. Coming across such symptoms, the physician or dentist must consider malignancies as well, and carry out medical and dental workups. PMID:24910668

    A sixty eight year-old woman with a long-standing history of hypertension, dizziness and a history of congenital heart disease presented with speech difficulties and disorientation. She was diagnosed with a brain abscess, confirmed by a stereotactic biopsy. Transthoracic echocardiographic evaluation revealed a persistent left superior vena cava (PLSVC) with an unroofed coronary sinus (URCS) along with a small secundum atrial septal defect. Her heart catheterization showed a partially unroofed coronary sinus along with a bidirectional shunt. She was referred for surgical closure of her unroofed coronary sinus and the secundum atrial septal defect. Her brain abscess responded well to antibiotic treatment. While waiting for open-heart surgery, she suffered from an acute myocardial infarction and underwent emergent percutaneous coronary intervention to the right coronary artery. Subsequently, she underwent elective surgical repair of the unroofed coronary sinus, along with closure of the atrial septal defect. When she was seen in follow-up she reported a complete resolution of her dizziness and felt more energetic. Unroofed coronary sinus syndrome (URCS) is a rare congenital cardiac anomaly in which there is a communication between the coronary sinus and the left atrium. While non-invasive imaging with echocardiography, MRI or CT is helpful in making the diagnosis, cardiac catheterization remains integral in the evaluation and management planning. Management is guided by the presence of clinical symptoms with consideration of repair when patients become symptomatic. Prognosis after surgery is excellent, recently transcatheter based treatment therapies are becoming more frequent. We present a rare case of URCS with PLSVC presenting as a cerebral abscess in late adulthood. She had bidirectional shunting manifesting as a cerebral abscess. She responded well to the corrective surgery and was doing well on follow up.

    We report a case of bilateral infero-medial orbital wall destruction, associated with loss of sinonasal architecture. The patient presented with intermittent horizontal diplopia following an acute on chronic infective sinusitis. Eight months previously the patient had developed a midline hard palate fistula for which a palatine prosthesis had been fitted. The broad differential diagnosis is discussed, though in this patient chronic cocaine abuse was identified as the underlying aetiology. Eye movement restriction worsened progressively with bilateral inflammation around the medial and inferior rectus muscles. Attempts to resolve the recurring cycle of sinus infection and inflammation by palatal fistula closure failed despite augmented techniques mobilising flaps from both nasal and palatal sides.

    Cryptococcal meningitis is a relatively common invasive fungal infection in immunocompromised patients, especially in solid organ transplant recipients. Clinical presentation typically includes fever, headache, photophobia, neck stiffness, and/or altered mental status. Unusual presentations may delay diagnosis. Therapy is challenging in renal transplant patients because of the nephrotoxicity associated with amphotericin B, the recommended treatment. We present a case of cryptococcal meningitis in a renal transplant recipient presenting as acute sinusitis with successful treatment using fluconazole as primary therapy.

    Intracranial metastasis of prostate cancer is rarely seen, and there are few studies in this regard in the literature. Most of these studies in the literature comprise the metastasis of prostate cancer to the sphenoid sinus, and metastasis to the frontal and ethmoid sinus is a much rare entity. Association of visual symptoms, epistaxis, headache, and hematuria may indicate a urologic malignancy in terms of the origin of the primary tumor. This study was aimed to present the prostate cancer case of a 73-year-old patient whose paranasal sinus tomograms revealed the presence of frontal and ethmoid sinus metastasis. PMID:27909626

    2015-01-01

    Background Cholesterol granulomas arising at the petrous apex can be treated via traditional open surgical, endoscopic, and endoscopic-assisted approaches. Endoscopic approaches require access to the sphenoid sinus, which is technically challenging in patients with conchal sphenoidal anatomy. Clinical Presentation A 55-year-old woman presented with intermittent headaches and tinnitus. Formal audiometry demonstrated moderately severe bilateral hearing loss. CT of the temporal bones and sella revealed a well-demarcated expansile lytic mass. MRI of the face, orbit, and neck showed a right petrous apex mass measuring 22 × 18 × 19 mm that was hyperintense on T1- and T2-weighted images without enhancement, consistent with a cholesterol granuloma. The patient had a conchal sphenoidal anatomy. Operative Technique Herein, we present an illustrative case of a low-lying petroclival cholesterol granuloma in a patient with conchal sphenoidal anatomy to describe an alternative high nasopharyngeal corridor for endoscopic transnasal transclival access. Postoperative Course Postoperatively, the patient's symptoms recovered and no complications occurred. Follow-up imaging demonstrated a patent drainage tract without evidence of recurrence. Conclusion In patients with a conchal sphenoid sinus, endoscopic transnasal transclival access can be gained using a high nasopharyngeal approach. This corridor facilitates safe access to these lesions and others in this location. PMID:26929897

    Cavernous sinus thrombosis not only presents with constitutional symptoms including fever, pain and swelling but also with specific findings such as proptosis, chemosis, periorbital swelling, and cranial nerve palsies. It is known to occur secondary to the spread of paranasal sinus infections in the nose, ethmoidal and sphenoidal sinuses. However, paranasal sinus infection of dental origin is rare. The following is a case of cavernous sinus thrombosis due to the spread of an abscess in the buccal and pterygomandibular spaces via buccal mucosal laceration. PMID:25247150

    We report a case of a 42-year-old man presenting with shortness of breath and palpitation on exertion, who was evaluated to have left sinus of Valsalva aneurysm rupturing into right atrium. This is a very rare congenital cardiac anomaly with variable clinical presentation ranging from asymptomatic detection on imaging to acute coronary syndrome and sudden cardiac death. Rupture is the most dreaded complication and usually manifests as an acute event. Aneurysmal dilation less commonly affects the left sinus and rupture into the right atrium is still rarer and a chronic insidious presentation as in this case is odd. PMID:23531926

    Esthesioneuroblastoma (ENB)-also known as olfactory neuroblastoma-originates primarily from the olfactory epithelium in the roof of the nasal cavity. We present here the 7th reported case of ENB arising from the sphenoidal sinus. We undertook a review of the case notes from the time of initial presentation and literature review of this topic. A 55-year-old male presented with a 3-year history of unilateral progressive nasal obstruction, epistaxis, difficult nasal-breathing, facial pain, frontal headache and blood-tinged discharge. Nasal examination revealed a glistening mass in right nasal cavity. Endoscopy-assisted transnasal excision was performed. Histologically, tumor was identified as small round cell tumor and confirmed by immunohistochemistry to be olfactory neuroblastoma (negative leucocyte common antigen, positive neurone specific enolase). Sphenoidal ENB is rare in the literature, and this presentation is the 7th reported case; in addition, surgical treatment is very challenging, and non-surgical treatment is used most commonly.

    A 74-year-old immunocompetent man admitted for severe retro-orbital headache was diagnosed with isolated sphenoiditis. At the time of scheduled surgery, the patient was mildly obtunded, and a head CT revealed a temporal lobe abscess. The patient underwent a left temporal craniectomy and a bilateral endoscopic sphenoid sinusotomy, which revealed gross fungal debris. The patient made a full recovery with resolution of abscess and sinus findings. Suspicion for intracranial infection should be raised in any sinus patient with neurological changes. Early diagnosis with imaging studies is extremely important for surgical drainage before permanent neurological sequelae.

    Objectives: We present the clinical and radiological features, treatment protocols, and medium-long-term results of our patients following surgery for paranasal sinus mucocele, along with a review of the relevant literature. Materials and methods: A total of 18 patients (11 women and 7 men) who underwent surgery for paranasal sinus mucocele at Kocaeli University Faculty of Medicine, Department of Otolaryngology, between 2006 and 2013 were examined retrospectively. The mean patient age was 41 (range 4-73). Demographic and radiological features, symptoms, treatment protocols, and postoperative outcomes were recorded. Results: The most frequently affected sinus was the maxillary sinus (n=9, 50%) followed by the frontal sinus (n=6, 33%) and sphenoidal sinus (n=3, 16%). The main symptom was headache. Endoscopic marsupialization of the mucocele was applied in all 18 patients, while frontal sinus exploration with the osteoplastic flap procedure was performed in one patient and the Caldwell-Luc operation was performed in another patient. The Caldwell-Luc procedure was subsequently required in one patient (6%) and endoscopic revision surgery was required in another patient (6%). Conclusion: Sinus mucocele that enlarges, eroding the surrounding bone tissue, and induces various clinical symptoms due to the impression of the expansile mass, is treated surgically, and must be planned carefully to prevent serious complications.

    Chronic lymphocytic leukaemia (CLL) is the most frequent form of leukaemia among adults in the Western world, presenting at a median age of 65 years. The diagnosis is usually made incidentally during routine blood examination while the disease is still in its early phase. We report a case of blindness of 24 hours due to acute sinusitis based on CLL localisation in a patient with undiagnosed CLL. Emergency endoscopic sinus surgery and intra- and extra-ocular orbital decompression were performed. The sinusitis resolved after surgery and intravenous antibiotics. Her vision improved within 24 hours and eventually recovered completely after six months. Her CLL remained in an indolent state, needing no active treatment. This case illustrates that blindness from a lymphoproliferative disorder may be treated with emergency endoscopic sinus surgery instead of conventional chemotherapy in order to salvage the vision first, even if the vision is lost for more than 24 hours.

    Manual segmentation of computed tomography (CT) datasets was performed for robot-assisted endoscope movement during functional endoscopic sinus surgery (FESS). Segmented 3D models are needed for the robots' workspace definition. A total of 50 preselected CT datasets were each segmented in 150-200 coronal slices with 24 landmarks being set. Three different colors for segmentation represent diverse risk areas. Extension and volumetric measurements were performed. Three-dimensional reconstruction was generated after segmentation. Manual segmentation took 8-10 h for each CT dataset. The mean volumes were: right maxillary sinus 17.4 cm(3), left side 17.9 cm(3), right frontal sinus 4.2 cm(3), left side 4.0 cm(3), total frontal sinuses 7.9 cm(3), sphenoid sinus right side 5.3 cm(3), left side 5.5 cm(3), total sphenoid sinus volume 11.2 cm(3). Our manually segmented 3D-models present the patient's individual anatomy with a special focus on structures in danger according to the diverse colored risk areas. For safe robot assistance, the high-accuracy models represent an average of the population for anatomical variations, extension and volumetric measurements. They can be used as a database for automatic model-based segmentation. None of the segmentation methods so far described provide risk segmentation. The robot's maximum distance to the segmented border can be adjusted according to the differently colored areas.

    Objectives: Placing implants in the posterior maxillary area has the drawback of working with scarce, poor quality bone in a significant percentage of cases. Numerous advanced surgical techniques have been developed to overcome the difficulties associated with these limitations. Subsequent to reports on the elevation of the maxillary sinus through the lateral approach, there were reports on the use of the crestal approach, which is less aggressive but requires a minimal amount of bone. Furthermore, it is more sensitive to operator technique, as the integrity of the sinus membrane is checked indirectly. The aim of this paper is to review the technical literature on minimally invasive sinus lift and compare the advantages of different techniques with Intralift™, a new technique. Study Design: The present study is a review of techniques used to perform minimally invasive sinus lift published in Cochrane, Embase and Medline over the past ten years and the description of the crestal sinus lift technique based on minimally invasive piezosurgery, with the example of a case report. Results: Only eight articles were found on minimally invasive techniques for sinus lift. The main advantage of this new technique, Intralift, is that it does not require a minimum amount of crestal bone (indeed, the smaller the width of the crestal bone, the better this technique is performed). The possibility of damage to the sinus membrane is minimised by using ultrasound based hydrodynamic pressure to lift it, while applying a very non-aggressive crestal approach. Conclusions: We believe that this technique is an advance in the search for less traumatic and aggressive techniques, which is the hallmark of current surgery. Key words: Sinus lift, surgical technique, minimally invasive surgery, ultrasound surgery. PMID:22143696

    Dural arteriovenous fistula (DAVF) of the transverse sinus with ophthalmic manifestations in young children are rare. We reviewed two cases of direct AVF of the transverse sinus with ocular manifestations managed at our institution. The first, a 2.5 years old male child presented with left exophthalmos. Angiography revealed AVF between the occipital artery and the transverse sinus. The second, a 2 years old female child, complained of left exophthalmos. Imaging studies showed bilateral direct AVFs of the transverse sinus with bilateral dysmaturation of the sigmoid sinus. Transarterial embolization was done in both cases. Clinical and radiological follow up revealed complete cure.This report suggests that DAVF of the transverse sinus supplied by the external carotid branches can present with ophthalmic manifestations especially if there is distal venous stenosis or obliteration involving sigmoid sinus. Transarterial embolization using coils and liquid embolic agents could be safe and feasible to obliterate the fistula. PMID:27226864

    Objective. We aim to describe the first case in the literature of allergic fungal sinusitis (AFS) presenting with hyperprolactinemia due to compression of the pituitary gland. Case Presentation. A 37-year-old female presented with bilateral galactorrhea and occipital headaches of several weeks. Workup revealed elevated prolactin of 94.4, negative pregnancy test, and normal thyroid function. MRI and CT demonstrated a 5.0 × 2.7 × 2.5 cm heterogeneous expansile mass in the right sphenoid sinus with no pituitary adenoma as originally suspected. Patient was placed on cabergoline for symptomatic control until definitive treatment. Results. The patient underwent right endoscopic sphenoidotomy, which revealed nasal polyps and fungal debris in the sphenoid sinus, consistent with AFS. There was bony erosion of the sella and clivus. Pathology and microbiology were consistent with allergic fungal sinusitis caused by Curvularia species. Prolactin levels normalized four weeks after surgery with resolution of symptoms. Conclusion. Functional endoscopic sinus surgery alone was able to reverse the patient's pituitary dysfunction. To our knowledge, this is the first case of AFS presenting as hyperprolactinemia due to pituitary compression. PMID:26998375

A delayed ethmoid pneumocele after sinus surgery has not previously been reported. Methods: A case report of a patient with a delayed ethmoid pneumocele after sinus surgery. The diagnostic workup, operative approach, and postoperative results were evaluated. Results: A 57-year-old female with a history of endoscopic sinus surgery 15 years prior presented with right eye proptosis and severe orbital and facial pressure. A maxillofacial computed tomography showed a markedly expanded air-filled right anterior ethmoid space with a dehiscent lamina papyracea, consistent with a pneumocele. Marsupialization of the pneumocele as well as a revision ethmoidectomy were performed, with a visible return of the orbital contents to a more natural position. The patient experienced worsened diplopia immediately postoperatively that resolved within two weeks. Conclusions: This case demonstrates that a pneumocele can present even years after endoscopic sinus surgery, and acute but temporary development or worsening of diplopia can result from surgical decompression of the pneumocele as the eye returns to its natural position.

    Tuberculoma involving the cavernous sinus is a rare presentation of CNS disease, with only twelve cases reported in previous literature. We report a case of a 48 year old woman who presented with a right cavernous sinus syndrome of 2 months duration. MRI showed a mass in the right cavernous sinus, and serologic workup revealed an elevated sedimentation rate and positive Quantiferon®-GOLD testing. 18-FDG PET-CT demonstrated a hypermetabolic 3 cm subcarinal lymph node, and lymph node biopsy showed caseating granuloma. Culture of lymphatic tissue grew drug-sensitive M. tuberculosis. The patient was treated with a non-standard 4-drug regimen and prednisone, with rapid improvement of symptoms and radiologic abnormalities. Total length of treatment was 12 months. In addition, we review the 12 cases found in literature, and discuss clinical features, diagnostic dilemmas, and approaches to treatment. PMID:26839786

    Aim To define direct anatomical relations of the sphenoidal (alae minores), ethmoidal sinuses and optic nerve, with an emphasis on determining the effect of age on pneumatisation and dehiscence. Methods This retrospective, descriptive study involved 60 consecutive patients: 30 patients younger than 30 and30 patients older than 60 years of age. All patients underwent computerized tomography(CT). The relationship of the optic nerve and the sphenoidal and ethmoidal sinuses was classified. The presence of dehiscence in the bone structures, forming the optic canal, was checked. Dehiscence was defined as absence of visible bone density located between the sinus and the optic nerve. Protrusion of the optic nerve into the sphenoidal sinus was defined as optic nerve surrounded by pneumatised space. Results The most common type of relation between the optic nerve and sphenoidal sinus was type I, where the optic nerve was immediately adjacent to the lateral or superior wall of the sphenoidal sinus, without impression on the sinus wall. Dehiscence was documented in 15 (25%) cases, it was more common in older patients (8, 27%) than in younger ones (7, 23%). The pneumatisation processes were more frequent in patients over 60 (5, 17%) than in those younger than 30 years (4, 13%). Conclusion Surgeons and ophthalmologists should be aware of high frequency of dehiscence of sphenoidal sinus walls when treating adult patients in our population, especially when evaluating risks and complications of surgical procedures or when diagnosing inflammatory or tumorous processes in the close vicinity of posterior paranasal sinuses.

  1. Cerebrospinal Fluid Rhinorrhea and Seizure Caused by Temporo-Sphenoidal Encephalocele

    2015-01-01

    This case report describes the symptoms and clinical course of a 35-year-old female patient who was diagnosed with a temporo-sphenoidal encephalocele. It is characterized by herniation of cerebral tissue of the temporal lobe through a defect of the skull base localized in the middle fossa. At the time of first presentation the patient complained about recurrent nasal discharge of clear fluid which had begun some weeks earlier. She also reported that three months earlier she had for the first time suffered from a generalized seizure. In a first therapeutic attempt an endoscopic endonasal approach to the sphenoid sinus was performed. An attempt to randomly seal the suspicious area failed. After frontotemporal craniotomy, it was possible to localize the encephalocele and the underlying bone defect. The herniated brain tissue was resected and the dural defect was closed with fascia of the temporalis muscle. In summary, the combination of recurrent rhinorrhea and a first-time seizure should alert specialists of otolaryngology, neurology and neurosurgery of a temporo-sphenoidal encephalocele as a possible cause. Treatment is likely to require a neurosurgical approach. PMID:25932300

    Dural arteriovenous fistulae (DAVFs) are a rare form of intracranial arteriovenous malformation. We present the case of a patient who presented in a previously undescribed manner with facial swelling and bruising initially misdiagnosed as cellulitis. He was found subsequently to have DAVFs of the sphenoparietal sinus that had hemorrhaged. The rarity of DAVFs at this location may account for this unique presentation. Successful treatment was achieved by transarterial embolization. PMID:24632907

    2017-01-01

    Metastases in the paranasal sinuses are rare; renal cell carcinoma is the most common cancer that metastasizes to this region. We present the case of a patient with a 4-month history of a rapidly growing mass of the nasal pyramid following a nasal trauma, associated with spontaneous epistaxis and multiple episodes of hematuria. Cranial CT scan and MRI showed an ethmoid mass extending to the choanal region, the right orbit, and the right frontal sinus with an initial intracranial extension. Patient underwent surgery with a trans-sinusal frontal approach using a bicoronal incision combined with an anterior midfacial degloving; histological exam was compatible with a metastasis of clear cell renal cell carcinoma. Following histological findings, a total body CT scan showed a solitary 6 cm mass in the upper posterior pole of the left kidney identified as the primary tumor. Although rare, metastatic renal cell carcinoma should always be suspected in patients with nasal or paranasal masses, especially if associated with symptoms suggestive of a systemic involvement such as hematuria. A correct early-stage diagnosis of metastatic RCC can considerably improve survival rate in these patients; preoperative differential diagnosis with contrast-enhanced imaging is fundamental for the correct treatment and follow-up strategy.

    As a rare cerebrovascular disease, cerebral venous thrombosis (CVT) is caused by various conditions including trauma, infection, oral contraceptive, cancer and hematologic disorders. However, iron deficiency anemia is not a common cause for CVT in adult. Posterior fossa infarction following CVT is not well demonstrated because posterior fossa has abundant collateral vessels. Here, we report a case of a 55-year-old man who was admitted with complaints of headache, nausea, and mild dizziness. The patient was diagnosed with isolated lateral sinus thrombosis presenting as cerebellar infarction. Laboratory findings revealed normocytic normochromic anemia due to iron deficiency, and the patient's symptoms were improved after iron supplementation.

    The purpose of this work was to present an anatomic reference for computed tomography (CT) for the paranasal sinuses of adult buffalo fit the use of anatomists, radiologists, clinicians and veterinary students. CT images with the most closely corresponding cross sections of the head were selected and studied serially in a rostral to caudal progression from the level of the interdental space to the level of the nuchal line. The anatomical features were compared with the dissected heads and skulls. The paranasal sinuses of buffalo comprise dorsal conchal, middle conchal, maxillary, frontal, palatine, sphenoidal (inconstant, small and shallow when present), lacrimal and ethmoidal that were identified and labelled according to the premolar and molar teeth as landmarks. The topographic description of all the compartments, diverticula, septa and communication of the paranasal sinuses in buffalo has been presented. The relationship between the various air cavities and paranasal sinuses was easily visualized.

    Fibrosarcoma of the paranasal sinuses is extremely rare pathology and there is limited report in the literature. We report synchronous presentation of maxillary sinus fibrosarcoma and gemistocytic astrocytoma which is, to our knowledge, unique in the literature. Both tumors metastases to other organ rarely and the metastatic spread of gemistocytic astrocytoma to fibrosarcoma or vice versa have also not been reported in the literature yet.

    Holt, Hunter Kegan; Serici, Anthony Joseph; Moftakhar, Roham

    2013-01-01

    Purpose Sometimes, intracranial pathology in the distal vasculature cannot be accessed by standard endovascular techniques because of occlusion or insurmountable tortuosity of theinternal carotid artery (ICA). A trans-sphenoidal surgical approach can follow a similar trajectory to the course of the supraclinoid ICA. This study evaluates the feasibility of a trans-sphenoidal approach to the supraclinoid ICA for endovascular access. Materials and Methods In a fresh cadaver head, the sphenoid sinus was dissected through a trans-sphenoidal route. Bone over the carotid prominence was removed to expose the ICA. The artery was catheterized using the Seldinger technique, and three-dimensional digital subtraction angiography was performed to evaluate the procedure. Results The catheter was successfully inserted into the supraclinoid ICA via the trans-sphenoidal route. Three-dimensional radiographic reconstruction confirmed placement of the catheter and the trajectory of the sheath into the supraclinoid ICA. Conclusion While the trans-sphenoidal route has innumerable disadvantages over the standard endovascular access techniques, this route could be considered when other treatment options are too risky or impractical.

    We present 2 patients with giant cell reparative granuloma (GCRG) of the sphenoid bone. The first patient is an 8-year-old boy with involvement of the greater wing, and the second is a 53- year-old man with a lateral pterygoid plate mass. Both patients presented with rapid expansion of lytic bone lesions, which had solid and cystic components and lacked matrix calcification. Biopsies were indeterminate for definitive diagnoses. The radiologic appearance, location, and incidence of the lesions, and the patient's age and medical history are helpful aids in narrowing the differential diagnosis of sphenoid bone lesions. However, the imaging and, occasionally, even the histologic findings may not suggest the specific diagnosis of GCRG, which must be added into the differential diagnosis of rapidly enlarging cystic bone lesions of the sphenoid bone.

    2011-12-01

    Rosai and Dorfman first described sinus histiocytosis with massive lymphadenopathy (SHML) in 1969 with an article detailing 4 cases in which they differentiated this disease entity from the grouping of diseases categorized as histiocytosis X, where it was previously classified. Also known as Rosai-Dorfman disease (RDD), it is clinically characterized as massive, painless, bilateral, symmetric cervical lymphadenopathy, with fever and leukocytosis. An 11-year-old African American boy was referred to our clinic for extraction of a severely decayed tooth #30 and evaluation of a large right-sided neck mass. Initially, the patient had been seen by his general dentist who had diagnosed the mass as an odontogenic abscess. After 2 courses of different antibiotics, no changes in the mass were noted. Subsequently, the patient was sent to the emergency department where CT revealed multiple right-sided neck masses with the largest measuring 4 × 2 cm. The patient underwent an incisional biopsy by otolaryngology and a diagnosis of necrotic lymph tissue was made. Upon our examination, the carious tooth #30 was felt to be an incidental finding and fine-needle aspiration cytology of the largest mass was performed in 2 places. This also provided a diagnosis of necrotic lymph tissue. In concert with the patient and his mother, the decision was made to excise the mass because of psychosocial concerns. A massive right-sided lymph node attached to the submandibular gland was found and excised without complication. Histologic examination with S-100 stain confirmed a diagnosis of RDD. The patient healed well following surgery and has experienced no further lymphadenopathy. This case presentation and review of the literature is unique, as the patient presented with unilateral cervical lymphadenopathy only. Open biopsy and 2 fine-needle aspirations all returned as necrotic lymph tissue. Obtaining the correct diagnosis was additionally hampered by coincidental dental pathology on the

    Curative endovascular treatment of sphenoid wing dural arteriovenous fistula (dAVF) with pure cortical venous drainage is challenging because of its rarity, lack of accessible dural sinus for transvenous embolization (TVE), and proximity of skull base vital regions. Direct surgery to disconnect venous reflux has been favored. We report the curative endovascular treatment of two sphenoid wing dAVFs with pure cortical venous drainage. One patient revealed complete obliteration of dAVF by a single session of transarterial embolization (TAE). As part of strategic TAE for this complex dAVF, we used a novel approach to create a complete flow-arrest condition in which coils and an occlusion balloon were combined. A liquid agent was then injected across the pathological fistula and into the parent venous apparatus, thereby occluding the lesion. The other patient was treated with percutaneous TVE after TAE was unsuccessful. With a specific strategy and appropriate devices, the microcatheter was successfully introduced through sigmoid sinus, transverse sinus, superior sagittal sinus, and refluxing cortical vein by puncture of the jugular vein. Coils were deployed at the venous side of the fistula, resulting in successful obliteration of the dAVF. Sphenoid wing dAVF with pure cortical venous drainage could be curable by endovascular treatment with proper strategy and instruments when anatomical condition permits.

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

    We report the utility of a pulsed water jet device in meningioma surgery. The presented case is that of a 61-year-old woman with left visual disturbance. MRI demonstrated heterogeneously enhanced mass with intratumoral hemorrhage, indicating sphenoid ridge meningioma on her left side. The tumor invaded the cavernous sinus and left optic canal, engulfing the internal carotid artery in the carotid cistern and encased middle cerebral arteries. During the operation, the pulsed water jet device was useful for dissecting the tumor away from the arteries since it was safe in light of preserving parent arteries. The jet did not cause any vascular injury and did not induce vasospasm as shown by postoperative symptomatology and MRIs. With the aid of pulsed water jet, we could achieve total resection of the tumor except for the piece within the cavernous sinus. The patient had no new neurological deficits after the operation. We consider the pulsed water jet as a useful device, especially when the need to dissect meningioma from parent arteries exists. The jet can help neurosurgeons simultaneously achieve tumor resection and preservation of blood vessels.

    Sinonasal undifferentiated carcinoma-related rhinogenic optic neuropathy is rare and may lead to visual loss. To the best of our knowledge, this is the first report of bilateral sequential visual loss induced by this etiology. It is important to differentiate between chronic sinusitis and malignancy on the basis of specific findings on magnetic resonance images. Surgical decompression with multidisciplinary therapy, including steroids, chemotherapy, and radiotherapy, is indicated. However, no visual improvement was noted in this case, emphasizing the rapid disease progression and importance of early diagnosis and treatment. PMID:26265644

    A precise knowledge of the anatomy of the paranasal sinuses is essential for the clinician. Conventional radiology does not permit a detailed study of the nasal cavity and paranasal sinuses, and has now largely been replaced by computerised tomographic (CT) imaging. This gives an applied anatomical view of the region and the anatomical variants that are very often found. The detection of these variants to prevent potential hazards is essential for the use of current of endoscopic surgery on the sinuses. In the present work, we have studied the anatomical variants observed in the nasal fossae and paranasal sinuses in 110 Spanish subjects, using CT in the coronal plane, complemented by horizontal views. We have concentrated on the variants of the nasal septum, middle nasal concha, ethmoid unciform process and ethmoid bulla, together with others of lesser frequency. The population studied showed great anatomical variability, and a high percentage (67%) presented one or more anatomical variants. Discounting agger nasi air cells and asymmetry of both cavities of the sphenoidal sinus, which were present in all our cases, the variations most often observed were, in order, deviation of the nasal septum, the presence of a concha bullosa, bony spurs of the nasal septum and Onodi air cells.

    We reported a case of cavernous sinus aspergillosis. A 62-year-old man complained of trigeminal neuralgia in the right V1 region. Neurological examination on admission showed ptosis, loss of light reflex and ophthalmoplegia externa in the right side. MRI enhanced with gadolinium demonstrated sphenoid sinusitis and mass lesion in the right cavernous sinus. MRA revealed right internal carotid artery occlusion. An open biopsy using the extradural temporopolar approach was performed. Pus discharge was observed from the cavernous sinus and histological examination showed hypha of Aspergillus. With early voriconazole treatment, the patient had improvement in headache, ptosis and ophthalmoplegia externa. Cavernous sinus aspergillosis is often found after sphenoiditis. It results in invasion to an internal carotid artery and worsens the patient's prognosis by cerebral infarction, so early diagnosis and treatment are important. We should consider aspergillosis as one of the differential diagnoses of a mass in the cavernous sinus. The epidural approach to this lesion was available to obviate aspergillus dissemination into the medullary cavity.

    The sphenoid ridge (posterior aspect of the lesser wings) is encountered in many intracranial procedures. Increased knowledge of its morphology and relationships is, therefore, of importance to the neurosurgeon and clinician who appreciate imaging of this anatomical region. We have quantitated this part of the sphenoid bone in dry human skulls (35) and made cadaveric (15) measurements between its parts and surrounding neuroanatomical structures in all three cranial fossae. The length of the left and right lesser wings was on average 4.2 and 4 cm, respectively. The mean widths of this bony part at its midline, midpoint, and lateral point (crista alaris) were 1.5 cm, 2.0 cm, and 2 mm, respectively. From the crista alaris the mean distances to the crista galli, V3 at its exit through the foramen ovale, entrance of the occulomotor nerve into the cavernous sinus, middle meningeal artery at its emergence from the foramen spinosum, and the facial and vestibulocochlear nerves at the internal auditory meatus were 4.9, 4.5, 5, 4.7, and 6.1 cm, respectively. From the midpoint of the lesser wing, the mean distances to the crista galli, V3 at its exit through the foramen ovale, entrance of the occulomotor nerve into the cavernous sinus, middle meningeal artery at its emergence from the foramen spinosum, and the facial and vestibulocochlear nerves at the internal auditory meatus were 4.2, 2.9, 3, 3.4, and 4.7 cm, respectively. From the anterior clinoid process of the lesser wing, the mean distances to the crista galli, V3 at its exit through the foramen ovale, entrance of the oculomotor nerve into the cavernous sinus, middle meningeal artery at its emergence from the foramen spinosum, and the facial and vestibulocochlear nerves at the internal auditory meatus were 4.3, 2.8, 1, 3.3, and 4.1 cm, respectively. Additional measurements between the parts of the sphenoid ridge and surrounding anatomical structures may assist the surgeon who operates in this region or the clinician who

    We describe the case of a 41 year-old woman who presented with a slight slowness of the right hand movement, which began four months prior to admission. Neurological examination showed slight rest tremor of the right hand, moderate bradykinesia and rigidity. She had been taking medication for Parkinson's disease, but without any benefit. The patient underwent a gadolinium-enhanced brain MRI, which showed a large left sphenoid wing meningioma with surrounding edema compressing the basal ganglia. Total excision of tumor was performed. The right hemiparkinsonian signs were completely resolved. This rare case underlines the significance of neuroimaging in patients presenting with Parkinson's disease especially in those patients with a relatively younger age at onset or unresponsive to medication.

    Ruptured Sinus of Valsalva (RSOV) is a rarely seen disease condition. RSOV can have varied presentations from being asymptomatic with just a cardiac murmur to profound hypotension. There has been simultaneous occurrence of RSOV with Infective Endocarditis (IE) in literature. Glomerulonephritis has also been reported in approximately 20% patients with IE. Large amount of proteinuria or decline in kidney functions is rarely encountered and mostly this finding has been incidental on routine evaluation. The co-existence of all the three conditions in a single patient is rare. This case was diagnosed to have RSOV with IE and was also diagnosed with post-infectious glomerulonephritis on renal biopsy. Patient was advised corrective cardiac surgery, but due to financial constraints, patient could not be operated and he died. Here, we report for the first time an unusual presence of both RSOV and sub-aortic membrane with IE complicated by glomerulonephritis. PMID:27891383

    A 40-year-old male presented with a single generalized tonic-clonic seizure. MRI revealed an enhancing, dural-based, left lateral sphenoid wing lesion suggestive of a meningioma. At microsurgical excision, the lesion was firm and relatively avascular. The histopathological report revealed S-100 positive histiocytic proliferation with lymphophagocytosis (emperipolesis) characteristic of the Rosai-Dorfman disease. The case and its management are discussed.

    A primary intraosseous cavernous hemangioma located at the sphenoid bone with extensive involvement of the orbital roof and the lateral wall of the orbit is very rare. A 48-year-old woman presented with progressive right exophthalmos and diplopia. CT showed a bony mass lesion in the right sphenoid bone extending to the orbital bone. MRI showed an abnormal lesion in the sphenoid bone, which was heterogeneously enhanced with gadolinium. All of the abnormal bone was surgically removed, and histological examination confirmed a cavernous angioma. We also present a brief clinical and radiological review of seven previously reported cases.

  12. Orbital reconstruction for pulsatile exophthalmos secondary to sphenoid wing dysplasia.

    Sphenoid wing dysplasia or absence of the greater sphenoid wing is a rare condition that is considered pathopneumonic for neurofibromatosis type 1 (NF1). It occurs in 4% to 11% of NF1 patients, and its precise cause is unclear. Some cases appear to be congenital, while others have demonstrated it to be a progressive degeneration of the orbital wall. In about half of cases, associated adjacent neurofibromas are described. Consistently, however, the clinical sequelae is herniation of the temporal lobe into the orbit, causing progressive proptosis and pulsatile exophthalmos. Reconstruction of the orbit has traditionally been with bone grafts, but due to problems with bone resorption and recurrence, titanium plates in conjunction with bone grafts have been reported. We present a case of a 6-year-old male patient who was first diagnosed with NF1 and associated absence of the greater sphenoid wing at the age of 2. Four years later, he was referred for reconstruction after the development of pulsatile exophthalmos. Surgical management included dissection of the dura of the temporal lobe off of the periorbita and skull base reconstruction with a combination of radial-shaped titanium mesh and split calvarial bone grafts. Postoperatively, there was near immediate resolution of the pulsatile exophthalmos, and follow-up at 1 year showed no recurrence.

    Case report of bilateral cavernous sinus syndrome due to primary non-Hodgkin lymphoma of the central nervous system in a patient infected by the human immunodeficiency virus. A 51-year-old male patient infected by the human immunodeficiency virus but without antiretroviral treatment developed paralysis of the V and VI cranial nerves. Imaging studies were obtained to investigate an orbital apex and a cavernous sinus syndrome. A computerized tomography scan of the orbit was normal but a high-resolution magnetic resonance imaging demonstrated bilateral enlargement of the cavernous sinus. Although primary lymphoma of the central nervous system is a rare condition, it should be considered in the differential diagnosis in immunocompromised patients who develop ocular motility abnormalities and imaging signs suggestive of infiltrative cavernous sinus lesions.

    Mucoceles are defined as chronic, cystic lesions in the paranasal sinuses. When the mucocele content becomes infected, the lesion is defined as mucopyocele. Most mucoceles are located in the frontal and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to the superior-medial region of the orbit, leading to ocular disorders; maxillary sinus presentation is rare. In the present article, the authors described a rare case of mucopyocele in the maxillary sinus. PMID:24688571

    Patient: Male, 76 Final Diagnosis: Guillain-Barré syndrome Symptoms: Bradycardia • refractory hypotension Medication: — Clinical Procedure: — Specialty: Cardiology Objective: Unusual clinical course Background: Guillain-Barré syndrome (GBS) is an acute inflammatory demyelinating polyneuropathy that is usually associated with preceding respiratory or gastrointestinal infection and has the hallmark manifestation of ascending flaccid paralysis. We report an atypical presentation of GBS. Case Report: A 76-year-old male presented with acute onset of diaphoresis and altered mental status. He subsequently developed severe bradycardia and refractory hypotension, which initially responded to dopamine infusion. A temporary pacemaker wire was placed to stabilize the heart rate but hypotension persisted. Acute autonomic dysfunction was suspected. Head and chest imaging was unrevealing. Lumbar puncture revealed albuminocytologic dissociation that was consistent with a diagnosis of GBS. Hospital course was complicated with acute kidney injury and metabolic acidosis. Plasmapharesis was initiated. The patient eventually died of multi-organ failure. Conclusions: Autonomic dysfunction is a known but rare presentation of GBS. In patients presenting with refractory bradycardia and hypotension, GBS should be considered in the differential diagnosis. PMID:28283677

    A 23-year-old Asian lady presented with a hard indurated midline neck swelling of 2 months duration without any upper aerodigestive tract or systemic symptoms of note. Her inflammatory markers were elevated and she was commenced on antibiotics. Ultrasound scan and fine needle aspiration cytology (FNAC) were inconclusive. A CT scan showed an ill-defined soft tissue mass anterior to and not well demarcated from the thyroid, and contiguous with a superior and anterior mediastinal mass. Incisional biopsy revealed necrosis and pockets of purulent material. Microbiology suggested a chronic pyogenic abscess negative for acid fast bacilli. She was treated with antituberculous therapy without resolution. She developed a discharging lateral neck mass with progressive increase of the mediastinal mass. She subsequently required a neck exploration and mediastinoscopy. Repeat mediastinal biopsies confirmed the diagnosis of Hodgkin’s disease and no organisms on culture. She was commenced on chemotherapeutic treatment with a satisfactory outcome. PMID:22689859

    Sphenoid wing dysplasia occurs in 3-7% of patients with neurofibromatosis type 1 (NF1). The typical radiological features are partial or complete absence of the greater wing of the sphenoid. This condition is slowly progressive and may result in temporal lobe herniation into the orbital cavity, producing pulsating exophthalmos and gross facial deformity. Thus, reconstruction of the orbit is important for both cosmetic and functional reasons. Traditional surgical treatment of sphenoid dysplasia involves split bone grafting and repair of the anterior skull base defect. However, several reports have demonstrated complications of graft resorption and recurrence of proptosis and pulsating exopthalmos. In this case series, we present two patients suffering from pulsating exophthalmos due to sphenoid dysplasia. Radiological and MRI studies demonstrated orbital enlargement and complete absence of the greater wing of the sphenoid. Surgical management of these patients involved dural defect repair, and the use of titanium mesh in conjunction with bone graft to act as a barrier between the orbit and the middle cranial fossa. The mesh was fixed by fine screws. Proptosis improved markedly post-operatively and resolved within a few weeks. Ocular pulsation subsided and remained quiescent with at least 1-year follow-up.

    Supracristal ventricular septal defect (SCVSD), a defect of the infundibular portion of the interventricular septum just below the right aortic cusp, occurs more frequently in Eastern Asian populations. SCVSD may be complicated by right sinus of Valsalva aneurysm (SoVA). We present the case of a 26-year-old male of Korean descent with a history of a childhood murmur who was referred to our institution for progressive heart failure symptoms. He was diagnosed with SCVSD and ruptured right SoVA based on history, physical exam, and echocardiography including three-dimensional transesophageal echocardiography with reconstructed surgical views. The patient underwent SCVSD closure, SoVA excision, and valve-sparing aortic root replacement. We reviewed the echocardiography literature regarding SCVSD and SoVA, and analyzed contemporary literature of SoVA and its relationship with SCVSD. We conclude that a higher prevalence of ruptured SoVA in Eastern Asians is likely related to a higher prevalence of underlying SCVSD in this population.

    Orbital metastasis in systemic cancer is known to occur and occurs in up to 7% of all systemic cancers. Orbital features typically present after the diagnosis of the primary tumor. In about 20% of cases, there is no known primary cancer at the time of presentation with orbital metastatic disease. Here we report a case of a 60-year-old male smoker, in whom proptosis, due to metastasis in greater wing of left sphenoid bone secondary to bronchogenic carcinoma, was the initial symptom. We could not find in literature metastasis to greater wing of sphenoid bone due to small cell carcinoma of lung.

    A man aged 35 years presented with chronic headache and earache of 1-year duration. He had progressive vision loss and diplopia since last 9 months. He also had pain over the face and episodic profuse epistaxis. On examination, perception of light was absent in the right eye and hand movements were detected at 4 m distance in the left eye. Imaging revealed a lobulated mass in the nasopharynx extending into the bilateral cavernous sinuses and sphenoid sinus with bony erosions. Biopsy of the nasopharyngeal mass revealed pathological features which are characteristic of IgG4 disease. His serum IgG4 levels and acute inflammatory markers were also elevated. The patient was started on oral corticosteroid therapy. Fever, headache and earache resolved early and there was gradual improvement in the vision of the left eye. After 6 months, visual acuity in the left eye was 6/9, but right eye visual acuity had no change. Follow-up imaging revealed a significant reduction in the size of the mass.

    The lateral limit of endoscopic endonasal surgery has yet to be defined. The aim of this study was to investigate the lateral limit of endoscopic endonasal surgery at the level of the sphenoid sinus. Access from the sphenoid sinus to the middle cranial fossa through the cavernous sinus triangles was evaluated by cadaver dissection. Anatomical analysis demonstrated that the medial temporal dura mater was exposed through the anterior area of the clinoidal triangle, anteromedial triangle, and superior area of the anterolateral triangle, indicating potential corridors to the middle cranial fossa. This study suggests that the cavernous sinus triangles are applicable in selected cases to manage middle cranial fossa lesions by endoscopic endonasal surgery. PMID:25446385

    The authors present 2 patients with greater sphenoid wing fractures that were treated surgically. This type of fracture is classified as a blow-in fracture of the lateral orbital wall. The first patient was a 16-year-old boy who was involved in a motor vehicle accident. Computed tomography (CT) disclosed a medial displacement of the inner wall of the greater sphenoid wing of the left orbit. He was unconscious for 3 days. After he recovered consciousness, he presented limited abduction of the left eye with diplopia in all gaze directions and mild left proptosis. Although these symptoms did not improve for 1 week, displaced bone fragments of the greater sphenoid wing were removed via the lateral orbital approach. The patient had a good postoperative course with progressive improvement in eye movement over the next several weeks. The second patient was a 22-year-old man whose face was hit in a fight. CT disclosed medial displacement of the inner wall of the greater sphenoid wing of the left orbit. Although the patient also presented limited abduction of the left eye on admission, this symptom improved gradually. However, diplopia in all gaze directions and mild left proptosis did not improve. Therefore, the displaced inner wall of the greater sphenoid wing was reduced via the lateral orbital approach. The patient showed a good postoperative course with progressive improvement over the next several weeks. This type of orbital fracture, which is classified as an orbital blow-in fracture, is relatively rare. This type of greater sphenoid wing fracture is caused by buckling of the orbital wall secondary to severe compression of the orbital rim. Surgical treatment using the lateral orbital approach through a hemicoronal skin incision afforded a wider operative field and better cosmetic result.

    The objective of the present study was to evaluate the state of the nasal cavity and paranasal sinuses in the children presenting with congenital cleft of upper lip and palate (CLP). A total of 23 children at the age from 9 to 16 years who had undergone the surgical treatment of the above malformations during the first year of life were examined. The comprehensive study including routine ENT examination, endoscopic examination of the nasal cavity and nasopharynx, and computed tomography has demonstrated that 50% of the patients with congenital cleft of upper lift and palate suffered the deflection of the nasal septum associated with hyperplasia of inferior turbinal bones. The children with congenital cleft of upper lip and palate were characterized by enhanced pneumatization of the anterior end of the middle turbinate despite the absence of well apparent differences between their paranasal sinuses and those of the healthy children, with the degree of pneumatization being consistent with the patient's age in both groups.

    Primary osteosarcoma of skull base is extremely rare. We present a case of primary osteosarcoma arising in greater wing of sphenoid in a child. Our patient had an incomplete excision after which he received adjuvant chemotherapy and radiotherapy. There was good response to adjuvant chemoradiotherapy and the patient is disease free at a follow-up of 18 months. Treatment of skull base osteosarcomas is difficult, as complete excision is often not possible. To the best of our knowledge, this is the first case of sphenoid wing osteosarcoma in childhood to be reported in literature.

    Mast cell tumors are found in most organs and tissues with variable biologic behavior in dogs. This case illustrates the clinical and magnetic resonance imaging (MRI) findings in a dog with disseminated mast cell tumor infiltrating the sphenoid bones. A 6-year-old male neutered Greyhound presented with a 3-day history of acute onset of blindness. General physical examination was normal. Neurological examination revealed mildly disorientated mental status, absent menace response in both eyes, bilaterally decreased vestibulo-oculocephalic reflexes and absent direct and consensual pupillary light reflex in both eyes. An electroretinogram indicated normal retinal function in both eyes. A lesion involving the middle and rostral cranial fossa was suspected. Hematology and serum biochemistry were normal except decreased urea (1.2 mmol/L). MRI of the head revealed heterogeneous signal intensity of the sphenoid bones on T2-weighted images and loss of their normal internal architecture. Cerebrospinal fluid analysis was normal. Abdominal ultrasound revealed hepatosplenomegaly and mesenteric lymphadenopathy. Fine needle aspirates were taken from the jejunal lymph nodes and the spleen. Results were consistent with disseminated mast cell tumor. The owner declined any treatment and the dog was euthanatized. Postmortem examination confirmed disseminated mast cell tumor affecting multiple organs, including the sphenoid bones. To our knowledge, this is the first case describing MRI features of disseminated mast cell tumor affecting the sphenoid bones and causing acute onset of blindness in a dog.

    The elucidation of patterns of cranial skeletal maturation and growth in fossil hominids is possible not only through dental studies but also by mapping different aspects of ossification in both extant African apes and humans. However, knowledge of normal skeletal development in large samples of extant great apes is flimsy. To remedy this situation, this paper offers an extensive survey and thorough discussion of the ossification of the posterior border of the sphenoid greater wing. Indeed, this area provides much information about basicranial skeletal maturation. We investigate three variants: the absence of the foramen spinosum and the position of both the foramen spinosum and the foramen ovale in relation to the sphenosquamosal suture. Providing original data about humans and 1,425 extant great ape skulls and using a sample of 64 fossil hominids, this study aimed to test whether different ossification patterns occurred during the course of human evolution. The incidence of three derived morphologies located on the posterior border of the sphenoid greater wing increases during human evolution at different geological periods. The evolutionary polarity of these three derived morphologies is assessed by outgroup comparison and ontogenetic methods. During human evolution, there is a clear trend for the foramen spinosum to be present and wholly located on the posterior area of the sphenoid greater wing. Moreover, in all the great ape species and in Australopithecus afarensis, the sphenosquamosal suture may split the foramen ovale. Inversely, the foramen ovale always lies wholly within the sphenoid greater wing in Australopithecus africanus, robust australopithecines, early Homo, H. erectus (and/or H. ergaster), and Homo sapiens. From ontogenetic studies in humans, we conclude that, during human evolution, the ossification of the posterior area of the sphenoid greater wing progressively surrounded the middle meningeal artery (passing through the foramen spinosum) and

    Background: Microsensor navigation has the potential to aid balloon sinus ostial dilation by providing real-time tracking of balloon devices within the complex anatomy of the sinonasal cavities. Objective: This feasibility study evaluated the incorporation of a new microsensor technology into a flexible guidewire for use with current instruments in balloon sinus ostial dilation. Methods: A retrospective study was conducted to include seven men and one woman (age range, 33–68 years), who underwent balloon sinus ostial dilation with flexible microsensor navigation in the operating room setting. All the procedures were performed at target sinuses with the patient under general anesthesia, in conjunction with subsequent endoscopic sinus surgery. Results: Balloon dilation was attempted at the maxillary (n = 3), frontal (n = 14), and sphenoid (n = 1) sinuses. In all the cases, the surgical navigation system displayed the flexible wire tip as it was advanced to the target sinus ostia; this visual feedback for wire position guided the balloon placement. Successful balloon dilation with assistance of flexible microsensor navigation was performed on most sinuses, except a single frontal sinus with adjacent type 2 frontal cells. Conclusion: Flexible navigation technology may be combined with balloon sinus technology to facilitate localization of instruments in the sinus anatomy. Additional optimization of both the device and software technology is warranted. PMID:28381323

We present a case of low-grade hemagioendothelioma of the skull in a 29-yr-old woman. She had pain, diplopia and exophthalmos of the left eye. Radiographic images showed a relatively well-demarcated, expansile osteolytic lesion with irregularly thickened trabeculae and calcifications in the left greater wing of sphenoid bone. Histologically, the tumor was an infiltrative vasoformative lesion. The vessels are generally well-formed with open or compressed lumina surrounded by endothelial cells showing mild atypia. It lacked frequent mitotic figures and severe atypia. Although excessive bleeding occurred during the operation, the mass was totally resected. Postoperative radiation was not necessary.

    The American College of Radiology (ACR) Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Here, we present the Appropriateness Criteria for cancers arising in the nasal cavity and paranasal sinuses (maxillary, sphenoid, and ethmoid sinuses). This includes clinical presentation, prognostic factors, principles of management, and treatment outcomes. Controversies regarding management of cervical lymph nodes are discussed.

    On the basis of strong research evidence, the pathogenesis of sinusitis involves 3 key factors: sinusostia obstruction, ciliary dysfunction, and thickening of sinus secretions. On the basis of studies of the microbiology of otitis media, H influenzae is playing an increasingly important role in the etiology of sinusitis, exceeding that of S pneumoniae in some areas, and b-lactamase production by H influenzae is increasing in respiratory isolates in the United States. On the basis of some research evidence and consensus,the presentation of acute bacterial sinusitis conforms to 1 of 3 predicable patterns; persistent, severe, and worsening symptoms. On the basis of some research evidence and consensus,the diagnosis of sinusitis should be made by applying strict clinical criteria. This approach will select children with upper respiratory infection symptoms who are most likely to benefit from an antibiotic. On the basis of some research evidence and consensus,imaging is not indicated routinely in the diagnosis of sinusitis. Computed tomography or magnetic resonance imaging provides useful information when complications of sinusitis are suspected. On the basis of some research evidence and consensus,amoxicillin-clavulanate should be considered asa first-line agent for the treatment of sinusitis.

    The aim of this study was the determination of bacteria present in maxillary and ethmoid cavities in patients with chronic sinusitis and to correlate these findings with bacteria simultaneously present in their nasopharynx. The purpose of this correlation was to establish the role of bacteria found in chronically inflamed sinuses and to evaluate if the bacteria present colonized or infected sinus mucosa. Nasopharyngeal and sinus swabs of 65 patients that underwent functional endoscopic sinus surgery were cultivated and at the same time the presence of leukocytes were determined in each swab. The most frequently found bacteria in nasopharynx were Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus spp., Streptococcus viridans and Streptococcus pneumoniae. Maxillary or ethmoidal sinus swabs yielded bacterial growth in 47 (72.31%) patients. The most frequently found bacteria in sinuses were Staphylococcus epidermidis, Staphylococcus aureus, Klebsiella spp. and Streptococci (pneumoniae, viridans and spp.). The insignificant number of leukocytes was present in each sinus and nasopharyngeal swab. Every published microbiology study of chronic sinusitis proved that sinus mucosa were colonized with bacteria and not infected, yet antibiotic therapy was discussed making no difference between infection and colonization. Chronic sinusitis should be considered a chronic inflammatory condition rather than bacterial infection, so routine antibiotic therapy should be avoided. Empiric antibiotic therapy should be prescribed only in cases when the acute exacerbation of chronic sinusitis occurs and the antibiotics prescribed should aim the usual bacteria causing acute sinusitis. In case of therapy failure, antibiotics should be changed having in mind that under certain circumstances any bacteria colonizing sinus mucosa can cause acute exacerbation of chronic sinusitis.

We report a patient whose seizures developed 4 years after a face trauma. Upward displacement of the sphenoid wing caused a contusion at the orbital surface of the frontal lobe. Computed tomography, magnetic resonance imaging and electroencephalographic findings are presented. The patient responded well to commonly used antiepileptic drugs.

    Background: There has been no previous case report of a patient whose visual acuity improved after long-term blindness caused by tumor invasion into the optic canal. Case Description: A 65-year-old Asian woman presented with a 6-month history of blindness caused by a meningioma located on the inner third of the sphenoid ridge. An operation was performed to prevent further tumor invasion into the cavernous sinus and contralateral optic nerve. During surgery, optic canal decompression was performed using an epidural approach. Subtotal removal of the tumor was achieved. Two days after the surgery, her left visual acuity recovered from blindness. Conclusion: Normally, long-term blindness caused by optic nerve compression by a brain tumor is regarded as irreversible, and even a surgical excision of the optic nerve is performed in some cases. However, because we experienced a case in which the patient recovered from long-term blindness after optic canal decompression, we believe that this surgical procedure should definitely be considered as an option.

    The aim of the present study was to estimate average age of the patients in both sexes treated for MS, distribution by sex, amount of dexter and sinister MS with and without the fistulas into the maxillary sinus, with and without the foreign-bodies, length of stay in the Department of Maxillofacial Surgery at Kaunas Hospital of University of Medicine during the period from 1999 till 2004. The retrospective data analysis of the patients' treated from chronic MS was made. 346 patients (213 females and 133 males) were treated for chronic MS. 55 cases of chronic dexter MS with a fistula into maxillary sinus, 98 cases of chronic dexter MS without a fistula, 45 cases of chronic sinister MS with a fistula, 112 cases chronic sinister MS without a fistula, 16 cases of foreign-bodies in dexter maxillary sinus, 20 cases of foreign-bodies in sinister maxillary sinus have been detected. The main age of the female was 46.6+/-15.0, the main age of the men was 42.1+/-14.4. Statictically significant difference in the age difference of the women and the men was found (p=0.0024). It was determined, that females diagnosed and treated with chronic MS were 1.6 times more than males during the period from 1999 till 2004 in Kaunas Hospital of University of Medicine. Females treated for chronic MS were 4.5 years older than males.

    ABSTRACT The 2- and 3-dimensional (3D) anatomy and the morphometric properties of the paranasal sinuses of the foal have received little or no attention in the literature. The aim of this study was to obtain details of the paranasal sinuses using multiplane CT imaging to create 3D models and to determine morphological and morphometric data for the sinuses using the 3D models. The heads of five female foals were used in this study. The heads were scanned using computed tomography (CT) in the rostrocaudal direction. After the heads had been frozen, anatomical sections were obtained in the scan position. The 3D models of sinuses and the skull were prepared using MIMICS®. These models were used to assess the surface area and volume of the sinuses, the width, height and orientation of the apertures connecting these sinuses and finally the planar relation of the sinuses with the skull. The right and left sides of all anatomical structures, except the sphenoid sinuses, had symmetric organization on CT images and anatomical sections. The total sinus surface area and volume on both sides were 214.4 cm2 and 72.9 ml, respectively. The largest and the smallest sinuses were the frontal sinus (41.5 ml) and the middle conchal sinus (0.2 ml), respectively. It was found that the planes bounding the sinuses passed through easily palpable points on the head. In conclusion, 3D modeling in combination with conventional sectional imaging of the paranasal sinuses of the foal may help anatomists, radiologists, clinicians and veterinary students.

    The specific clinical feature of mastoidities that developed in a patient presenting with chicken pox was the rapid progress in temporal bone destruction with partial thrombosis of the sigmoid sinusis in the absence of typical manifestations of mastoiditis. The pronounced destructive changes found in a series of CT images were regarded as the indications for urgent antromastoidotomy with the puncture of the sigmoid sinusis.

    Gangliocytic lesions of the pituitary gland producing Cushing's disease are extremely rare entities that may exist with or without a pituitary adenoma. The latter have been designated mixed pituitary adenoma-gangliocytomas, the majority of which produce growth hormone, not adrenocorticotropin (ACTH), and are localized to the anterior gland. We now report an immunocompetent woman with hypercortisolism who presented with an intranasal aspergilloma eroding the bony sellar floor. The fungal ball was contiguous with, and extended into, a large neurohypophyseal-centered mass. Transsphenoidal resection revealed a gangliocytic lesion of the posterior gland with small clusters of intimately admixed ACTH-immunoreactive adenoma cells as the cause of her Cushing's disease. Rare transitional sizes and shapes of cells coupled with immunohistochemical findings supported interpretation as advanced neuronal metaplasia within an ACTH adenoma. This mixed ACTH adenoma-gangliocytoma is the first example to present clinically with an opportunistic infection.

    Chronic sinusitis is a relatively common diagnosis throughout the US. In patients with an otherwise unremarkable medical history the treatment is typically supportive, requiring only clinical evaluation. We present the case of a 25-year-old male with a history of chronic sinusitis that was brought to our emergency department with new-onset seizure. Three days before he had presented to his usual care facility with two days of headache and fever and was discharged stating headache, subjective fever, and neck stiffness. After further investigation he was diagnosed with a mixed anaerobic epidural abscess. The evaluation and management of chronic sinusitis are based on the presence of symptoms concerning for complication. Prompt investigation of complicated sinusitis is essential in preventing debilitating and fatal sequelae. Our case study underscores the importance of early diagnosis and appropriate management.

    The paper presents different forms of sinusitis in children and adults as well as the patomechanism of sinusitis of infective and non-infective origin. The role of bacterial infection has been discussed. Participation of major pathogens of URTI such as S. pneumoniae, H. influenzae and M. catarrhalis has been highlighted and the factors influencing growth of their antibiotic-resistant stains. Guidelines concerning antibiotic therapy in children and adults, depending on disease course, age and factors influencing growth of resistant stains have been presented. Causes of failure in treatment of sinusitis have been analysed eg. in case of bacterial biofilm growth or non-neutrophilic inflammation forms. Antimicrobial treatment concerns mainly acute and aggravated infections. In case of chronic sinusitis, antibiotic therapy is complementary to surgical treatment.

  8. More actors, different play: sphenoethmoid cell intimately related to the maxillary nerve canal and cavernous sinus apex.

    The sphenoid sinus is one of the most morphologically variable and surgically important structures of the skull base. Located below the sella turcica, neighbored by parasellar regions, such as the orbital apex, pterygopalatine fossa and lateral sellar region (cavernous sinus), it is clinically related to these and surgically relevant as corridor for various approaches. Moreover, at the sphenoethmoidal junction, important variations occur, most of these related to the presence of the Onodi cells and the intrasinusal protrusions of the optic nerve. That is why any identified and previously undescribed morphological variation at that level must be added to the well-established protocols, clinical and surgical. During a retrospective CT study of the sphenoid sinus anatomical features a previously unreported morphology was encountered and is reported here. It refers to a unilateral sphenoethmoid cell (SEC), Onodi-positive, not only overriding the superior aspect of the sphenoid but also its lateral side to get intimately related to the maxillary nerve. As that SEC expanded medially to the cavernous sinus apex, it altered the usual endosinusal morphological correlations and also added itself within the limits of the Mullan's triangle. It appears so that such postero-infero-lateral extended pneumatization of an Onodi cell alters the surgical landmarks and also can blur clinical pictures, by adding maxillary and pterygopalatine signs and symptoms.

    A 55-year-old woman presented with a 1-week history of vision loss in the right eye associated with proptosis and diplopia. Past medical history was significant for high-grade leiomyosarcoma of the uterus status post total abdominal hysterectomy and bilateral salpingo-oophorectomy and postoperative pelvic radiation 18 months prior to presentation. Staging studies at the time of initial diagnosis of uterine leiomyosarcoma showed no evidence for metastatic disease. At presentation, CT and MRI showed a well-circumscribed 3.0 cm x 3.6 cm x 2.4 cm mass centered in the right greater sphenoid wing, extending into the middle cranial fossa and the superior and lateral orbital wall. Biopsy of the orbital mass revealed a poorly differentiated high-grade leiomyosarcoma, consistent with recurrent metastatic disease from the uterus. The patient subsequently underwent radiation treatment followed by a left orbital exenteration 6 months after the orbital biopsy. A left thoracostomy was performed 8 months after the orbital biopsy for a metastatic nodule in the left lower lobe of the lung. The clinicopathologic findings of this rare metastatic orbital lesion are presented.

  10. Unusual venous sinuses.

    2007-01-01

    The dural venous sinuses lie in between the two layers of the dura mater. The dural venous sinuses are important, because they receive blood from the brain and the cranial bones. All sinuses are related to the inner surface of the skull, except for the inferior sagittal and the straight sinus. The sinuses related to the inner surface of the skull produce impressions on it. During routine ostelogical teaching for undergraduate medical students, we observed an unusual oblique sinus, which connected the right and the left transverse sinuses. This unusual oblique sinus measured 2 cm and had a course from the right to the left side. The superior sagittal sinus turned onto the right but at a much higher level than the left transverse sinus. Although these sinuses communicated with each other, the normal position of the confleunce of the sinus (meeting point of superior sagittal sinus, right and left transverse sinus and the occipital sinus) was not seen. The impression meant for the posterior lobe of the left cerebral hemisphere was distinctly greater than that of the right side. The presence of such an anomaly suggests a possible developmental defect or handedness of the individual. The knowledge of the anatomical variations of the dural venous sinuses may have great clinical implications during venography, shunt surgeries and also helpful for neurologists and radiologists in addition to academic interest (Fig. 2, Ref 10) Full Text (Free, PDF) www.bmj.sk.

    Structured training in endonasal endoscopic sinus surgery (EESS) and skull base surgery is essential considering serious potential complications. We have developed a detailed concept on training these surgical skills on the lamb’s head. This simple and extremely cheap model offers the possibility of training even more demanding and advanced procedures in human endonasal endoscopic surgery such as: frontal sinus surgery, orbital decompression, cerebrospinal fluid-leak repair followed also by the naso-septal flap, etc. Unfortunately, the sphenoid sinus surgery cannot be practiced since quadrupeds do not have this sinus. Still, despite this anatomical limitation, it seems that the lamb’s head can be very useful even for the surgeons already practicing EESS, but in a limited edition because of a lack of the experience and dexterity. Only after gaining the essential surgical skills of this demanding field it makes sense to go for the expensive trainings on the human cadaveric model. PMID:26413487

    2007-01-01

    Meningiomas of the sphenoid wing (SW) frequently show an invasive pattern of growth and cause destruction of the adjacent structures. As a result, the rate of recurrent SW meningiomas is as high as 30%. Cytogenetic investigations showed no aberrations specific to invasively growing meningiomas. During this study, the authors evaluated 10 invasive and 5 non-invasive SW meningiomas via comparative genome hybridization (CGH) (matrix CGH), by using the gene chips of GenoSensor Array micromatrixes. The mean number of aberrations in the tumor cells was much greater in case of invasive meningiomas (67.4 versus 40.5 in case of non-invasive SW meningiomas. Furthermore, in invasive SW meningiomas, there were frequently losses in loci 1p, 6q, and 14q and gains in loci 15q and 10, which had been predetermined as molecular markers of stepwise progression of meningioma. Thus, the presence of a complex cytogenetic profile and progression-associated chromosome aberrations in benign SW meningiomas is linked with the increase of their invasive potential. Due to the fact that there are no well-defined adjuvant therapy regimens for recurring meningiomas at present, the revealed genomic aberrations may become potential targets for searching for drugs and a therapeutic intervention in future.

    2001-02-01

    We report two patients with abnormal development of the lesser wing of the sphenoid bone, globe, optic nerve and cerebral hemisphere without stigmata of neurofibromatosis type 1. The lesser wing of the sphenoid bone was abnormally formed and was not ossified ipsilateral to the dysmorphic eye and underdeveloped cerebral hemisphere. Maldevelopment of the sphenoid wing may interfere with the normal closure of the optic vesicle and normal growth of encephalic structures, possibly by disturbing developmental tissue interactions. These patients may exhibit a type of restricted primary sphenoid dysplasia, while the sphenoid dysplasia of neurofibromatosis type 1 may be secondary to orbital or ocular neurofibromas and other factors associated with that disease.

    Osteochondroma is rarely found in oral and maxillofacial regions. The majority of reported osteochondromas occurred in mandibular areas; their occurrence in bones developed by intramembranous ossification is extremely rare. In this report, a case of osteochondroma arising from the pterygoid process of the sphenoid is described. Radiological investigations showed a large bony mass under the left great wing of the sphenoid and involving the left parapharyngeal space. The tumour was compressive to the mandibular ramus and pharyngeal cavity, causing marked disturbance of mouth opening and secretory otitis media. Histopathological examination confirmed the lesion to be osteochondroma.

    With a medium containing citrate as the carbon and energy source, 10 clostridial strains were isolated from various mud samples. Characterization of these strains revealed that they all belonged to the same species, Clostridium sphenoides. Strains of this organism obtained from culture collections were also able to grow citrate, whereas 15 other clostridial species tested were not. Citrate was fermented by C. sphenoides to acetate, ethanol, carbon dioxide, and hydrogen. Experiments with stereospecifically 14C-labeled citrate indicated that citrate lyase was involved in citrate degradation. Images PMID:869540

    We present a case of odontogenic maxillary sinusitis whose sinonasal symptomatology was thought to be the consequence of a previous midfacial trauma. The patient was admitted to the Clinic of Oral and Maxillofacial Surgery after more than 10 years of exacerbations of sinonasal symptoms, which began to plague soon after a facial contusion. We decided to perform CT of paranasal sinuses, and despite the absence dental symptomatology, the dental origin of sinusitis was discovered. The majority of sinonasal symptoms resolved after appropriate dental treatment, and there was no need for nasal or sinus surgery.

    Aggressive fibromatosis (AF) is a rare, locally aggressive, proliferative fibroblastic lesion affecting musculoaponeurotic structures, most often, of the limbs and trunk. Intracranial AF is extremely rare and requires aggressive treatment to prevent recurrence. We present a case of a 34 year-old male with AF involving intracranial structures causing panhypopituitarism and diabetes insipidus. Patient was admitted to hospital because of polyuria, polydipsia, and loss of libido, impotence, hearing loss, and gait disturbance. On cranial magnetic resonance imaging, the lesion extended through the sphenoid sinus into the both pterygoid recesses, destroying the left lateral wall of the sphenoid sinus and invading the retroorbital area. There was also a distinct lesion in the hypothalamic area. The tumor was markedly isointense on both T2- and T1-weighted images relative to gray matter, and enhanced strongly after administration of gadolinium. The patient underwent partial resection of the lesion via a transcranial approach. The pathological examination of the mass was reported as AF. No other sites were found to be involved by thorax and abdominal tomography. Hormonal assessment of hypothalamic-pituitary dysfunction revealed panhypopituitarism with central diabetes insipidus. Replacement therapy was instituted. In this case, standard treatment of wide-field surgical resection was impossible. On the basis of reports that radiotherapy is an effective treatment for this kind of tumor, we administered radiation to the affected area, since chemotherapy and hormonal treatment of non-resectable tumors are not satisfactory. To our knowledge, this is the first reported case of AF presenting as panhypopituitarism with central diabetes insipidus.

    We describe a rare case of an extensive primary cranial Ewing's sarcoma located in the greater wing of the sphenoid bone with extension to the orbit, the endocranium, the parapharyngeal and infratemporal space. The patient presented with diplopia, anosmia and prolapse of the left eye. He was given chemo- and radiotherapy and was free of symptoms on re-examination 1.5 years later. The prognosis of Ewing's sarcoma in the absence of surgery is uncertain, but prompt treatment appears to have a satisfactory therapeutic outcome. In the future, more cases should be studied in order to investigate the biological behaviour of a primary cranial Ewing's sarcoma.

A severe stenosis involved the intracranial internal carotid artery and the proximal segments of the middle and anterior cerebral arteries. Endovascular dilatation was followed by complete surgical resection. Preoperative mild aphasia and hemiparesia resolved completely after surgery. Endovascular angioplasty of arterial trunks and their branches can be proposed before the resection of skull base meningiomas encasing these arteries to decrease the risk of perioperative brain ischemia related to their surgical manipulation or vasospasm.

    2015-01-01

    Background: Immunosuppressive therapy, prolonged antibiotic use, and intrathecal injections are known risk factors for the development of invasive aspergillosis. Central nervous system (CNS) aspergillosis can manifest in many forms, including mycotic aneurysm formation. The majority of the mycotic aneurysms presents with subarachnoid hemorrhage after rupture and are associated with high mortality. Only 3 cases of true mycotic aneurysms have been reported following trans-sphenoidal surgery. Case Description: A 38-year-old man was admitted with nonfunctioning pituitary adenoma for which he underwent trans-sphenoidal surgery. Three weeks later, he presented with cerebrospinal fluid (CSF) rhinorrhea and meningitis. He was treated with intrathecal and intravenous antibiotics, stress dose of glucocorticoids, and lumbar drain. The defect in the sphenoid bone was closed endoscopically. After 3 weeks of therapy, he suddenly became unresponsive, and computed tomography of the head showed subarachnoid hemorrhage. He succumbed to illness on the next day, and a limited autopsy of the brain was performed. The autopsy revealed extensive subarachnoid hemorrhage and aneurysmal dilatation, thrombosis of the basilar artery (BA), multiple hemorrhagic infarcts in the midbrain, and pons. Histopathology of the BA revealed the loss of internal elastic lamina and septate hyphae with an acute angle branching on Grocott's methenamine silver stain, conforming to the morphology of Aspergillus. Conclusion: The possibility of intracranial fungal infection should be strongly considered in any patient receiving intrathecal antibiotics who fails to improve in 1–2 weeks, and frequent CSF culture for fungi should be performed to confirm the diagnosis. Since CSF culture has poor sensitivity in the diagnosis of fungal infections of CNS; empirical institution of antifungal therapy may be considered in this scenario. PMID:26759738

    2015-01-01

    Cerebrospinal fluid (CSF) leak is one of several complications that can occur after traumatic skull base injury. Although most patients present soon after the injury occurs, some can present years later, with resulting morbidity and the need for additional procedures. We present a case of a patient with a sphenoid sinus CSF leak who presented 12 years after a closed head injury that included a sphenoethmoid skull base fracture. We also reviewed the literature on this topic, with a discussion of previous reports of CSF leaks that occurred months, years, or decades after trauma. A late onset CSF leak appears to be a rare but important complication of traumatic skull base injury. This case highlights the need for clinicians to remain vigilant to the possibility of delayed CSF rhinorrhea, even years after traumatic head injury.

    Dermoid cysts are common periorbital lesions. They usually occur near the superolateral orbital rim, indenting but not extending within the bony outer table. We present an unusual case of a dumbbell-shaped dermoid cyst underlying the temporalis muscle with extension into the lateral wing of the greater sphenoid bone, approaching the optic canal. The cyst was successfully removed en bloc via a small skull base craniectomy without spillage of cyst contents. The patient recovered well without neurological or visual sequelae.

  11. A Rational Approach to Sinus Augmentation: The Low Window Sinus Lift

    PubMed Central

    Zaniol, Alex

    2017-01-01

    Sinus augmentation is a well-known approach to treating alveolar bone ridge atrophy in the posterior maxilla. The preparation of the lateral window is crucial. Its size, design, and position in the vestibular sinus wall may affect the intra- and postsurgical complication rates and affect the intrasurgical activity of both surgeons and assistants. The present paper describes a rational technique that also exploits the guided surgery approach for design and preparation of a lateral window for sinus augmentation, the Low Window Sinus Lift. To illustrate the use of this approach, a case is presented in which the 50-year-old patient had the left maxillary first molar extracted, followed two months later by sinus augmentation and placement of three implants. One year after delivery of the definitive prosthesis, all three implants were successful, and the prosthesis was fully functional. Controlled studies should be undertaken to assess whether this technique provides significant advantages compared to other sinus augmentation approaches. PMID:28337349

    Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus hypoplasia, type 2 shows significant sinus hypoplasia with narrowed infundibular passage and hypoplastic or absent uncinate process, and type 3 is cleft like maxillary sinus hypoplasia with absent uncinate process. CT and endoscopic examination usually complement each other in diagnosing MSH. PMID:25548709

    Chronic sinusitis is a major cause of morbidity today. Regional variations in the incidence of this disease have been reported. The aim of this study was to evaluate the incidence of fungal infection as the causative agent of chronic sinusitis among Iranian patients. A cross sectional hospital based study was designed; the patients underwent paranasal sinus washing and maxillary sinus biopsy. All specimens were studied by light microscopy. Fungal culturing was employed to confirm diagnosis. The patients underwent Computed Tomography for sinus evaluation. Of 162 participants, 12 samples from patients showed fungal elements, 2 of them Aspergillus fulvous (1.2%), 9 of them Alternaria species (5.56%) and 1 of them Psilomysis (0.6%). All patients presented radiologic evidence of sinusitis, ranging from mucosal thickening to total opacity. In conclusion, results obtained showed a low prevalence of fungal sinusitis among Iranian patients with chronic sinusitis. Findings also showed that Alternaria is the most causative agent.

    Pilonidal sinuses usually occur in the sacrococcygeal area in young men, and occasionally can be found in other ectopic sites. We present a retrospective case review on unusual locations of pilonidal sinuses in the past 4 years. The lesion sites were as follows: one on the penis, two on the scalp, two on the abdomen, one on the neck, two in the groin and two in the axilla. Abdominal and penile lesions are uncommon, but the other locations reported are unusually rare. To our knowledge, the groin has not been reported previously as a site of a pilonidal sinus, although the histological appearance of hidradenitis suppurativa may well resemble it. When trying to clarify the pathogenesis of these occurrences, we found that recurrent hair removal was a common characteristic of the patients we contacted, and this may have been the initiating trauma.

    A mathematical model that describes the relationship between sinus pressure and nerve discharge frequency of the carotid sinus baroreceptor is presented. It is partly based upon the single-fiber data obtained by Clarke from the sinus nerve of a dog. The model takes into account what is currently known about the physiology of the baroreceptor. It consists of two nonlinear ordinary differential equations and eight free parameters. With one set of values for these eight parameters, the model reproduces well the experimental results reported by Clarke for positive ramp pressure inputs. Only three parameters needed to be adjusted in order to fit the dynamic data. The remaining five were obtained from static and steady-state data. PMID:5056961

    Anomalous origination of coronary artery from the opposite sinus (ACAOS) is a rare coronary artery anomaly. Right ACAOS with interarterial course is a type of ACAOS, which conveys a high risk for myocardial ischemia or sudden death. We reported a case of right ACAOS with interarterial course in otherwise healthy young male. He was asymptomatic, until an obligatory medical check-up with treadmill test showed a sign of positive ischemic response. Further work-up revealed that he had right ACAOS with interarterial course. Watchful observation was applied to him, while strenuous physical activity and competitive sport were absolutely prohibited. PMID:26885410

    2011-12-01

    Atypical patterns of metastatic spread from colorectal primary tumors are often misdiagnosed, with potential implications for the clinical outcome. Metastatic diffusion to the splanchnocranium is extremely rare in colorectal cancer. A histological proof of diagnosis is rarely obtained and therapeutic management is a challenge. We describe the case of a 46-year-old patient who presented with a radiologically proven sphenoid wing metastasis. The patient presented with left-sided exophthalmos while receiving systemic chemotherapy for relapsed high-risk colorectal cancer. A left sphenoid wing metastasis was proven by a head computed tomography scan. A metastatic spread to the sino-nasal tract is regarded as a poor prognosis determinant in colorectal cancer and presents a unique set of diagnostic and therapeutic challenges. The compression of noble structures such as the optic nerve holds serious implications in terms of quality of life but there is insufficient evidence clarifying whether radiotherapy or surgery represent the best option for these patients, leaving the therapeutic plan to be decided case by case.

  18. Cholesterol granuloma of the maxillary sinus.

    2006-06-01

    Cholesterol granuloma (CG) of the maxillary sinus is very rare. In this study, the searching of the literature was performed with the keywords of cholesterol granuloma and maxillary sinus. All retrieved literature were reviewed throughout to identify and analyze all individual characteristics. Two additional cases in our hospital were also included. The result showed that, in the overall 37 cases, the ratio of male to female was about 3:1. Caucasian (14/37) and Turkish (10/37) were reported more frequently. CG of maxillary sinus had an opposite sex predilection compared with the fungus balls of the maxillary sinus. In addition, the comorbidity of these two diseases was found only in one patient in the literature. These results suggested that the different mechanisms other than poor aeration of the maxillary sinus played a role in the formation of CG of maxillary sinus. The diagnosis for CG of the maxillary sinus before operation is difficult, but the clear golden yellow rhinorrhea and hemorrhagic signs may provide a good diagnostic evidence. The symptoms were vague and about half of the patients presented with non-specific symptoms. Therefore, it seemed reasonable that CG of the maxillary sinus was under diagnosed in the clinical practice. Treatment consists of complete excision via Caldwell-Luc or endoscopic approach and provides a good prognosis. Bilateral involvements are rare but possible in this disease entity.

    We describe an atypical man with diffuse large B cell lymphoma localized to the sphenoid wing and adjacent cavernous sinus, initially presenting with isolated ipsilateral facial pain mimicking trigeminal neuralgia due to invasion of Meckel’s cave but subsequently progressing to intra-axial extension and having synchronous features of systemic lymphoma. Primary central nervous system lymphoma is uncommon, accounting for approximately 2% of all primary intra-cranial tumors, but its incidence has been steadily increasing in some groups [1]. It usually arises in periventricular cerebral white matter, reports of lymphoma in extra-axial regions are rare [2]. This man highlights the importance of maintaining lymphoma in the differential diagnosis of tumors of the skull base presenting with trigeminal neuralgia-like symptoms. PMID:25865026

    Neurofibromatosis type 1 disease is characterized by pigmented cutaneous lesions and generalized tumors of a neural crest origin and it may affect all the systems of the human body. Sphenoid dysplasia is one of the characteristics of this syndrome and it occurs in 5-10% of the cases; further, abnormalities of the sphenoid wings are often considered pathognomonic. However, complete agenesis of a sphenoid wing is very rare. We report here on an unusual case of neurofibromatosis type 1 disease with the associated absence of a sphenoid wing that was diagnosed by using multidetector computed tomography.

    Meningioma en plaque (MEP) is a rare tumor characterized more by its clinical and biological behavior than its histological appearance. Hyperostosis of the skull is one of the characteristic signs of MEP. This bony change can produce clinical symptoms and signs in MEP by pressing against adjacent structures. The authors report a rare case of an osteolytic MEP extending from the sphenoid wing into the orbital wall, middle fossa, and temporalis muscle. PMID:19096543

    Neurogenic monocular nasal field defects respecting the vertical midline are quite uncommon. We report a case of a unilateral nasal hemianopia that was caused by compression of the left optic nerve by a sphenoid wing meningioma. Histological examination revealed that the pathology of the meningioma was consistent with that of an atypical meningioma, which carries a guarded prognosis with increased chance of recurrence. The tumor was debulked surgically, and the patient's visual field defect improved.

    The greater wing of the human sphenoid bone is pierced by several foramina, which contain, as a main element, the venous anastomoses between the interior of the skull and the extracranial veins. Since data concerning these foramina are scarce in the literature, studies comprising the frequency of occurrence and morphology of the foramina of the greater wing of the human sphenoid bone were undertaken on 100 macerated skulls. We found that the foramen ovale is divided into 2 or 3 components in 4.5% of cases. Moreover, the borders of the foramen ovale in some skulls were irregular and rough. This may suggest, on radiological images, the presence of morbid changes, which might be the sole anatomical variation. Concurrent with the foramen ovale are accessory foramina. The foramen of Vesalius and the cavernous foramen were present in 17% and 33% of cases, respectively. The foramen of Vesalius was always single and the cavernous foramen also occurred in multiple form. The foramen spinosus and the foramen rotundum occurred as permanent elements of the skulls studied. The mean area of the foramina measured, excluding the foramen ovale, was not considerable, which may suggest that they play a minor role in the dynamics of blood circulation in the venous system of the head.

  4. Microbiology of sinusitis.

    2011-03-01

    Most sinus infections are viral, and only a small proportion develops a secondary bacterial infection. Rhinoviruses, influenza viruses, and parainfluenza viruses are the most common causes of sinusitis. The most common bacteria isolated from pediatric and adult patients with community-acquired acute purulent sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes. Staphylococcus aureus and anaerobic bacteria (Prevotella and Porphyromonas, Fusobacterium and Peptostreptococcus spp.) are the main isolates in chronic sinusitis. Pseudomonas aeruginosa and other aerobic and facultative gram-negative rods are commonly isolated from patients with nosocomial sinusitis, the immunocompromised host, those with HIV infection, and in cystic fibrosis. Fungi and Pseudomonas aeruginosa are the most common isolates in neutropenic patients. The microbiology of sinusitis is influenced by the previous antimicrobial therapy, vaccinations, and the presence of normal flora capable of interfering with the growth of pathogens.

    Malignant tumours of maxillary sinus are rare. They are usually diagnosed in the late stages when they perforate the sinus walls. The presence of large air space in the maxillary sinus facilitates asymptomatic growth of the sinus malignancy. The clinical presentation of these tumours depends on the sinus wall involved by the disease. The medial wall is usually the first to become eroded, leading to nasal obstruction, epistaxis or discharge. Rarely, symptoms of maxillary sinus carcinoma can resemble dental infection and the affected patients may visit dental clinic seeking treatment. This report presents a case of carcinoma of maxillary sinus mimicking odontogenic infection. Computed tomographic findings explained the reason for the present lesion to masquerade as an inflammatory condition. The importance of advanced imaging modalities for prompt identification of such lesions is discussed. PMID:27790593

    Background Proximity of the dental roots to the sinus floor makes dental disease a probable cause of maxillary sinusitis. The aim of this study was to find out if maxillary sinus pathologic changes were more prevalent in patients with dental disease and to evaluate the performance of computed tomography (CT) in analyzing and detecting apical periodontitis and other odontogenic causes on the maxillary sinusitis etiology in a Portuguese Caucasian population. Material and Methods Retrospective cohort study. The total sample of 504 patients and their CT was included in this study. The patients were from a private dental clinic, specializing in oral surgery, where the first complaint was not directly related to sinus disease, but with dental pathology. For each patient, the etiological factors of maxillary sinusitis and the imaging CT findings were analyzed. All the axial, coronal and sagittal CT slices were evaluated and general data were registered. The latter was selected based on the maxillary sinus CT published literature. Results 32.40% of patients presented normal sinus (without any etiological factor associated), 29.00% showed presence of etiological and imaging findings in the maxillary sinus, 20.60% had only imaging changes in the maxillary sinus and 18.00% of patients presented only etiological factors and no change in the maxillary sinus. Conclusions Radiological imaging is an important tool for establishing the diagnosis of maxillary sinus pathology. These results indicate that the CT scan should be an excellent tool for complement the odontogenic sinusitis diagnosis.

    Extra oral sinus of odontogenic origin occurs when the purulent by-products of dental pulp necrosis spread along the path of least resistance from the root apex to the skin on the face. Patients presenting with cutaneous sinus usually visit a general physician or dermatologist first, as the lesion can mimic various dermatologic pathologies, ranging from an infected sebaceous cysts to a basal cell carcinoma. Despite systemic antibiotics, symptoms often persist causing further confusion, and at times leading to unnecessary surgical interventions. The location of this sinus in the head and neck region should lead the physician to seek a dental opinion in order to avoid misdiagnosis. PMID:25506495

    The identification of unidentified human remains through the comparison of antemortem and postmortem radiographs has found wide acceptance in recent years. Reported here is the forensic case of an unidentified adult male who had died as the result of a traffic accident, after which the body was identified by matching images of ante- and postmortem radiographs of the frontal sinus. A general discussion on identification using frontal sinus radiographs is presented, highlighting the reliability of this method, in reference to the uniqueness of the frontal sinus in humans. However, it also notes a few difficulties, especially in reference to the X-ray technique in cases where antemortem radiographs are available and a potentially larger number of anatomical, pathological or traumatic features are present. The comparison of frontal sinus outlines is recommended when it may become necessary to provide quantitative substantiation for forensic identification based on these structures.

    Purpose Penetration of the clivus is required for surgical access of the brain stem. The endoscopic transclivus approach is a difficult procedure with high risk of injury to important neurovascular structures. We undertook a novel anatomical and radiological investigation to understand the structure of the clivus and neurovascular structures relevant to the extended trans-nasal trans-sphenoid procedure and determine a safe corridor for the penetration of the clivus. Method We examined the clivus region in the computed tomographic angiography (CTA) images of 220 adults, magnetic resonance (MR) images of 50 adults, and dry skull specimens of 10 adults. Multiplanar reconstruction (MPR) of the CT images was performed, and the anatomical features of the clivus were studied in the coronal, sagittal, and axial planes. The data from the images were used to determine the anatomical parameters of the clivus and neurovascular structures, such as the internal carotid artery and inferior petrosal sinus. Results The examination of the CTA and MR images of the enrolled subjects revealed that the thickness of the clivus helped determine the depth of the penetration, while the distance from the sagittal midline to the important neurovascular structures determined the width of the penetration. Further, data from the CTA and MR images were consistent with those retrieved from the examination of the cadaveric specimens. Conclusion Our findings provided certain pointers that may be useful in guiding the surgery such that inadvertent injury to vital structures is avoided and also provided supportive information for the choice of the appropriate endoscopic equipment.

    Bilateral simultaneous sampling of the inferior petrosal sinuses is an extremely sensitive, specific, and accurate test for diagnosing Cushing disease and distinguishing between that entity and the ectopic ACTH syndrome. It is also valuable for lateralizing small hormone-producing adenomas within the pituitary gland. The inferior petrosal sinuses connect the cavernous sinuses with the ipsilateral internal jugular veins. The anatomy of the anastomoses between the inferior petrosal sinus, the internal jugular vein, and the venous plexuses at the base of the skull varies, but it is almost always possible to catheterize the inferior petrosal sinus. In addition, variations in size and anatomy are often present between the two inferior petrosal sinuses in a patient. Advance preparation is required for petrosal sinus sampling. Teamwork is a critical element, and each member of the staff should know what he or she will be doing during the procedure. The samples must be properly labeled, processed, and stored. Specific needles, guide wires, and catheters are recommended for this procedure. The procedure is performed with specific attention to the three areas of potential technical difficulty: catheterization of the common femoral veins, crossing the valve at the base of the left internal jugular vein, and selective catheterization of the inferior petrosal sinuses. There are specific methods for dealing with each of these areas. The sine qua non of correct catheter position in the inferior petrosal sinus is demonstration of reflux of contrast material into the ipsilateral cavernous sinus. Images must always be obtained to document correct catheter position. Special attention must be paid to two points to prevent potential complications: The patient must be given an adequate dose of heparin, and injection of contrast material into the inferior petrosal sinuses and surrounding veins must be done gently and carefully. When the procedure is performed as outlined, both inferior

    Chronic sinusitis is one of the most common presenting complaints of all doctor visits in the United States and Europe, with more than 13% of people affected in any given year. This disease has a wide range of impact on communities. Patients with recurrent or chronic sinusitis report a deteriorative sense of general health and vitality, when compared to general population. In our Department we perform about 600 functional endoscopic sinus surgeries (FESS) per year. Chronic rhinosinusitis represents a spectrum of inflammatory and infectious processes concurrently affecting the nose and paranasal sinuses. Among chronic paranasal sinusitis one must single out paranasal sinusitis with and without polyps. In the paranasal sinusitis patomechanism the blockage of natural ostium plays one of the most important roles. The closure of sinus proper ventilation passages leads to the triggering of many pathological occurrences within mucous membrane of this region. The treatment of paranasal sinusitis is diversified and involves a surgical procedure as well as anti-inflammatory and antiallergic drugs (medications) and mucolytics. Its purpose is to clear the nose through the elimination of bacterial infection, liquidating and removal of lying discharge and the restoration of the proper muco-ciliary transportation, and through this the improvement of local condition and faster recovery. In this work the usage of carboxycysteine to treat paranasal sinus conditions has been presented.

    Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, parts of the human skeleton can be used for identification, such as dental records, thorax, vertebrae, shoulder, and frontal sinus. It has been established in prior investigations that the radiographic pattern of frontal sinus is highly variable and unique for every individual. This has stimulated the proposition of measurements of the frontal sinus pattern, obtained from x-ray films, for skeletal identification. This paper presents a frontal sinus recognition method for human identification based on Image Foresting Transform and shape context. Experimental results (ERR = 5,82%) have shown the effectiveness of the proposed method.

    Meningiomas are known to be associated with female sex hormones. Worsening neurological symptoms or newly diagnosed meningiomas have been described in the context of elevated levels of sex hormones, for example, in pregnancy. To the authors' knowledge, tumor shrinkage after the normalization of hormones has not been described, even if it is known that neurological deficits due to meningioma compression may improve after giving birth. A 32-year-old female patient presented with severe headache and vision disturbances at the end of her second pregnancy. Magnetic resonance imaging revealed an extended mass at the lateral left-sided sphenoid wing that was suspected to be a meningioma. After delivery, the patient's symptoms improved, and MRI obtained 2 months postpartum showed significant shrinkage of the lesion. Significant tumor shrinkage can occur after pregnancy. Thus, repeat imaging is indicated in these patients.

    Objective To analyze the variations in the angle basal sphenoid skulls of adult humans and their relationship to sex, age, ethnicity and cranial index. Methods The angles were measured in 160 skulls belonging to the Museum of the Universidade Federal de São Paulo Department of Morphology. We use two flexible rules and a goniometer, having as reference points for the first rule the posterior end of the ethmoidal crest and dorsum of the sella turcica, and for the second rule the anterior margin of the foramen magnum and clivus, measuring the angle at the intersection of two. Results The average angle was 115.41°, with no statistical correlation between the value of the angle and sex or age. A statistical correlation was noted between the value of the angle and ethnicity, and between the angle and the horizontal cranial index. Conclusions The distribution of the angle basal sphenoid was the same in sex, and there was correlation between the angle and ethnicity, being the proportion of non-white individuals with an angle >125° significantly higher than that of whites with an angle >125°. There was correlation between the angle and the cranial index, because skulls with higher cranial index tend to have higher basiesfenoidal angle too. PMID:25295452

    Surgery of the posterior ethmoid and sphenoid sinuses can be challenging. In 1999, a technique was described for identification of the superior turbinate and utilizing it as a landmark in endoscopic posterior ethmoidectomy and sphenoidotomy. Although this was more than a decade ago, it has not been supported by further studies. In our practice, we have routinely adopted this technique, and have modified it to allow further orientation during endoscopic surgery of the posterior sinuses. To describe a review of our technique, and to prospectively assess the value of the superior turbinate as a useful landmark during endoscopic posterior ethmoidectomy and sphenoidotomy. Fifty patients listed for endoscopic posterior ethmoidectomy with or without sphenoidotomy were included in a prospective study utilising our surgical technique. Data were collated for the success or failure of identification of the landmarks, and for any complications during the surgery. A total of 93 sides of endoscopic posterior ethmoidectomy and 73 sides of endoscopic sphenoidotomy were performed. The superior turbinate was identified in 100% of the cases. The coronal part of the superior turbinate basal lamella was identified in 60.22% of the cases, and the axial part in 88.17% of the cases. The natural sphenoid ostium was identified medial to the posterior part of the superior turbinate in 98.63% of the cases. The axial part of the superior turbinate basal lamella was a constant landmark for the level of the sphenoid ostium. The number of transverse septae between the axial part of the superior turbinate basal lamella and the skull base was studied, and was found never to exceed one septum. No major complications were recorded. One case of small posterior septal perforation was detected with no post-operative effects. Our study represents the first report of identifying the two parts of the superior turbinate basal lamella intra-operatively. It also represents the first report of using the axial

    Cerebral sinus venous thrombosis (CSVT) is a rare phenomenon that can be seen with some frequency in young patients. CSVT is a multifactorial condition with gender-related specific causes, with a wide clinical presentation, the leading causes differ between developed and developing countries, converting CSVT in a condition characterized by a highly variable clinical spectra, difficult diagnosis, variable etiologies and prognosis that requires fine medical skills and a high suspicious index. Patients who presents with CSVT should underwent to CT-scan venography (CVT) and to the proper inquiry of the generating cause. This disease can affect the cerebral venous drainage and related anatomical structure. The symptoms may appear in relation to increased intracranial pressure imitating a pseudotumorcerebri. Prognosis depends on the early detection. Correcting the cause, generally the complications can be prevented. Mortality trends have diminished, and with the new technologies, surely it will continue. This work aims to review current knowledge about CSVT including its pathogenesis, etiology, clinical manifestations, diagnosis, and treatment. PMID:24347950

Methods Cases identified by CPT codes as BCD(2,717) or traditional ESS(31,059) were extracted from the State Ambulatory Surgery Databases 2011 for California, Florida, Maryland and New York. Patient demographicss, surgical center and surgeon volume, mean charge and OR time were compared. Results 33,776 patients underwent sinus surgery in the included states in 2011. 4.6% of maxillary, 5.6% of sphenoid and 13.9% of frontal procedures were performed using BCD. Adjusted analyses found increased use of BCD in patients with chronic diseases(p<0.001). Patients who had a limited sinus surgery were less likely to have BCD compared to patients who had all 4 sinuses instrumented(p<0.001). Surgeons who performed a medium[odds ratio 1.38(1.14–1.65)] or high[odds ratio 1.71(1.42–2.07)] volume of ESS were more likely to use BCD compared to those who performed a low volume(p <0.001), however among surgeons who utilized BCD there was minimal relationship between the percentage of surgeries performed with BCD and the surgeon's total number of cases(R squared=0.055). Compared to traditional ESS, the median charges for maxillary/ethmoid procedures(Mini-ESS) involving BCD were approximately $4,500(p<0.001) and maxillary/ethmoid/sphenoid/frontal procedures(Pan-ESS) were approximately $2,950(p=0.003) greater, while the median OR time involving BCD was 8 minutes less for Mini-ESS procedures(p=0.01) but not statistically different for Pan-ESS procedures(p=0.58). Conclusions In the study sample, balloon technology was used in 8.0% of ESS cases in 2011. Procedures using BCD were on average more expensive compared to traditional ESS procedures, with minimal decrease in OR time. Level of Evidence 2c PMID:25180840

    We systematically reviewed the existing literature supporting the efficacy and safety of sinus preservation management for frontal sinus fractures in the modern era of endoscopic frontal sinus surgery. A systematic review of the English literature for the targeted objective was conducted using the PubMed database between January 1995 and August 2008. The PubMed database was queried using two major search terms of frontal sinus fracture or frontal sinus injury along with manual review of citations within bibliographies. Citations acquired from the primary search were filtered and relevant abstracts were identified that merited full review. Articles were identified that included any cohort of patients with frontal sinus fractures involving the frontal sinus outflow tract or posterior wall with sinus preservation management. A total of 231 citations were generated, and 56 abstracts were identified as potentially relevant articles. Sixteen articles merited full review, with seven articles meeting inclusion criteria for sinus preservation. There were 515 total patients in the studies with 350 patients managed with frontal sinus preservation. Similar short-term complications and effectiveness were found between fractures managed with sinus preservation and those with traditional management. Sinus preservation appears to be a safe and effective management strategy for select frontal sinus fractures. More transparent reporting of management strategies for individual cases or cohorts is needed. A standardized algorithm and categorization framework for future studies are proposed. Longer-term follow-up and larger prospective studies are necessary to assess the safety and efficacy of sinus preservation protocols.

    The paper presents clinical cases illustrating two sinus floor lifting technique performed for dental implant placement in areas with maxillary sinus floor atrophy: bone block fixation for vertical augmentation (used for immediate implant placement by sinus floor atrophy to 1 mm thickness) and perforation closure. Sinus floor perforations wider than 5 mm were repaired by mandible bone graft providing the possibility of immediate implantation. Bone block was fixed between cortical layers of the maxilla with no internal fixation. Free bone blocks provide additional primary stability of dental implants.

  3. Nasopharyngeal carcinoma presenting with rapidly progressive severe visual disturbance: a case report

    PubMed Central

    2014-01-01

    Introduction Nasopharyngeal carcinoma is one of the most difficult tumors to diagnose correctly at the initial phase because of the occasional lack of nasal symptoms. The perineural spread of the trigeminal nerve is one of the most common and important routes in the intracranial paracavernous extension of nasopharyngeal carcinoma, but visual loss is very rare. Case presentation We report the case of a 54-year-old Japanese man with nasopharyngeal carcinoma, who presented with rapid and severe disturbance of left monocular visual acuity and eye movement with a 10-month history of ipsilateral otitis media and facial pain. Magnetic resonance imaging revealed a lesion in the left fossa of Rosenmüller, pterygopalatine fossa, sphenoid and ethmoid sinus, and the left cavernous sinus extending to the orbital apex through the superior orbital fissure. The histopathological diagnosis was nonkeratinizing undifferentiated nasopharyngeal carcinoma. Epstein–Barr virus was detected by in situ hybridization. Although focal radiotherapy induced remarkable tumor shrinkage and relieved ocular motor disturbance and facial pain, his visual acuity did not improve. Conclusion The awareness of cranial nerves in addition to intracranial and orbital apex involvement, as in this case, is important for appropriate diagnosis and treatment planning of nasopharyngeal carcinoma.

    Modern diagnostic tools like fiberoptic nasal endoscopy and CT imaging of the sinuses are very sensitive in helping clinicians diagnose sinus disease; we may now reevaluate the symptoms and signs most useful in making a clinical diagnosis of rhinosinusitis. Two major systems of classification and diagnostic criteria relating headaches and sinus disease have achieved currency-that of the International Headache Society (IHS) (1988) and the more recent task force recommendations of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) (1997). This report compares and contrasts the different starting points, certain assumptions, and conflicting conclusions of these two classification systems and recommends a cooperative alliance of the IHS and AAO-HNS when these diagnostic criteria are revised.

    We report the case of a 24 year-old pregnant woman, seen at the neurology service by presenting agitation, hallucinations, mental confusion, headache, vision loss, aphasia and seizures. The neuroradiologic exam was compatible with thrombosis in dural sinus and cortical veins. Treatment with abciximab was accomplished and the mechanical lysis of the thrombus was made obtaining restoration of cerebral vein flow. After the procedure, she presented frontal hematoma which was withdrawn surgically. We discuss this infrequent pathology in clinical picture, pathogenesis, image exams and therapeutics.

    Trephination of the equine sinuses is a common surgical procedure in sedated standing horses. Standing sinus flap surgery has become increasingly popular in equine referral hospitals and offers several advantages over sinusotomy performed under general anesthesia, including reduced patient-associated risks and costs; less intraoperative hemorrhage, allowing better visualization of the operative site; and allows surgeons to take their time. Other minimally invasive surgical procedures include sinoscopic surgery, balloon sinuplasty, and transnasal laser sinonasal fenestration. Despite the procedure used, appropriate indications for surgery, good patient selection, and familiarity with regional anatomy and surgical techniques are imperative for good results.

    Cavernous sinus thrombosis (CST) represents a rare but devastating disease process that may be associated with significant long-term patient morbidity or mortality. Rapid diagnosis and aggressive medical and surgical management are imperative for patients with CST. We present the case of a 24-year-old pregnant woman with intraorbital abscess and CST secondary to Streptococcus milleri. Surgical intervention included orbital abscess drainage and dental extraction, medical therapy included intravenous antibiotic, heparin, and methylprednisolone and an elective cesarean section was performed. The latter was the key point to resolution the disease.

    Background Although balloon sinus dilation is a treatment option for adults with chronic rhinosinusitis (CRS), there have been few studies performed in pediatric patients. Methods This study was designed as a prospective, multicenter, single‐arm investigation. Children (2 to 21 years old) with CRS who had failed medical management were treated with balloon sinus dilation and followed to 6 months postprocedure. Results Fifty children were treated at 4 centers; 33 participants were 2 to 12 years old (mean ± standard deviation age: 6.6 ± 2.2 years) and 17 participants were >12 to 21 years (mean age: 15.7 ± 2.5 years). A total of 157 sinus dilations were attempted (98 maxillary, 30 frontal, and 29 sphenoid sinuses) and all were successful with no complications. Significant improvement in the Sinus and Nasal Quality of Life Survey (SN‐5) was seen for all children between baseline and 6 months (4.6 ± 1.2 vs 1.7 ± 0.8; p < 0.0001) and 92% improved by a minimal clinically important difference (MCID) of 1.0 or more. Those children aged 2 to 12 years with standalone balloon dilation also showed significant SN‐5 improvements between baseline and follow‐up (4.5 ± 1.0 vs 1.9 ± 0.8; p < 0.0001). Multivariate regression analysis showed no differences or associations of SN‐5 improvement at 6 months with the presence of allergy, asthma, or concomitant procedures. For adolescents, overall 22‐item Sino‐Nasal Outcome Test (SNOT‐22) mean scores were also significantly improved at 6 months (42.2 ± 19.2 vs 10.4 ± 9.7; p < 0.0001). Conclusion Balloon sinus dilation is safe and appears effective for children with CRS aged 2 years and older. PMID:27888649

    An 62-year-old man presented visual impairment and generalized seizure. Brain CT performed on the day of admission showed thrombus in the right transverse sinus, and DWI showed high intensity areas in the bilateral occipital and parietal lobes. According to bilateral occipital lobe lesions, we considered his visual impairment as cortical blindness. He was diagnosed as venous sinus thrombosis and intravenous heparin, edaravone and osmotic diuretics were administered. MR venography performed after starting of intravenous treatment showed flow gap in the left transverse sinus but no abnormalities in the right transverse sinus. On the second day of hospitalization, his cortical blindness showed improvement and thrombus in the right transverse sinus were disappeared. This indicated that his left transverse sinus originally hypoplastic, thrombus and hemostatis in the right transverse sinus (his dominant side) caused his cortical blindness and generalized seizure. There was a recanalization in the right transverse sinus after heparin therapy.

    2000-01-01

    Controversy regarding the use of anticoagulants, the evacuation of the sinus, or the use of medical treatment alone surrounds the treatment of lateral sinus thrombosis. Treatment of an epidural abscess associated with coalescent mastoiditis is much less controversial-drainage is usually recommended. The differing treatments of these complications mandate accurate diagnosis. The advent of more sophisticated radiological studies has facilitated diagnosis of these complications; however, tests are not infallible. We present three cases in which preoperative imaging demonstrates an epidural abscess mimicking lateral sinus thrombosis by compression of the vessel. A false-positive computed tomography (CT) or magnetic resonance imaging (MRI) study may lead to the wrong diagnosis and, consequently, improper treatment. In light of this possibility, we recommend surgical exploration in all such cases. ImagesFigure 1Figure 2Figure 3Figure 4 PMID:17171148

    Citrate lyase from Clostridium sphenoides was purified 72-fold with a yield of 11%. In contrast to citrate lyase from other sources the activity of this enzyme was strictly dependent on the presence of L-glutamate. The purified enzyme was only stable in the presence of 150 mM L-glutamate or 7 mM L-glutamate plus glycerol, sucrose or bovine serum albumin. Changes of the L-glutamate pool and of enzyme activity in growing cells of C. sphenoides indicated that citrate lyase activity in this organism was regulated by the intracellular L-glutamate concentration. Citrate lyase isolated from C. sphenoides, Rhodopseudomonas gelatinosa and Streptococcus diacetilactis was investigated by electron microscopy using the negative staining technique. Three different projections of enzyme molecules were observed: 'star' form, 'ring' form and 'triangle' form. In samples from R. gelatinosa and S. diacetilactis, star and ring forms occurred in a ratio of about 1:9. Using the enzyme from S. diacetilactis it was demonstrated that this ratio could be altered in favour of the star form by the addition of citrate or tricarballylate. The triangle form was observed in less than 1% of all evaluated molecules and may represent a transition form. In lyase samples from C. sphenoides there existed a correlation between enzyme activity and the proportion of stars and rings at varying concentrations of L-glutamate.

    The fourth branchial pouch sinus (FBPS) is a rare translaryngeal anomaly with diverse manifestations, including neonatal stridor and recurrent deep neck infection. Review of the world literature reveals 23 reports of sinuses consistent with fourth pouch origin. We present two additional cases, including the only example of a right-sided FBPS. Retrograde excision, beginning at the piriform apex, ensures complete removal of the tract and protection of the recurrent nerve. The posterior border of the thyroid ala must be resected or retracted for adequate exposure. Failure to remove the translaryngeal portion of the tract almost guarantees recurrence.

    ABSTRACT Ophthalmic manifestations of allergic fungal sinusitis (AFS) are rare, but can occur in advanced disease. A 32-year-old man with advanced AFS presented with severe bilateral vision loss and restricted ocular motility. Magnetic resonance imaging and histological analysis confirmed active chronic AFS. Functional endoscopic sinus surgery was performed, with adjunctive steroid therapy. Although AFS is a reasonably well-recognised entity, severe disease causing bilateral visual deficits is rarely encountered. This can confound the diagnosis and appropriate treatment. Ophthalmologists should thus be aware of compressive optic neuropathy as a complication of advanced AFS to prompt early treatment and mitigate visual loss. PMID:27928361

    A dermal sinus is a congenital defect arising from a closure failure of the neural tube that results in different degrees of communication between the skin and the central nervous system. A dermal sinus can occur anywhere from the root of the nose to the conus medullaris, and the occipital location is the second most common. Dermal sinuses are often found in association with dermoid or epidermoid cysts and less frequently with teratomas. Patients with an occipital dermoid cyst associated with a dermal sinus can develop meningitis and/or abscesses as the first clinical manifestation of the disease due to the dermoid cyst itself becoming abscessed or to the formation of secondary abscesses; few cases of the formation of secondary abscesses have been reported. We present a case of a dermoid cyst associated with an infected dermal sinus and posterior development of cerebellar abscesses and hydrocephalus.

    The most common reason of orbital infections is sinusitis. Orbital complications of sinusitis are mostly seen in children. Loss of vision and intracranial infections are among the complications of sinusitis. Prompt diagnosis and treatment is very important in the management of orbital complications. The orbital complication can be in the form of cellulitis or abscess. A retrospective review of 26 pediatric patients with orbital complications due to sinusitis was presented in this study. Of 26 patients, there were 13 cases of preseptal cellulitis, 2 cases of orbital cellulitis, and 11 cases of subperiosteal abscess. We grouped the preseptal and orbital cellulites in one category and the subperiosteal abscess in the other. All patients in the cellulitis group recovered by medical treatment. All the patients were treated by surgical drainage. Early diagnosis and appropriate treatment method are vital for the treatment of orbital complications secondary to sinusitis.

    Diagnosing sinusitis remains a challenge for primary care physicians. There is a need for a simple, office-based technique to aid in the diagnosis of sinusitis without the cost and radiation risk of conventional radiologic imaging. We designed a low-cost near-infrared (NIR) device to transilluminate the maxillary sinuses. The use of NIR light allows for greater interrogation of deep-tissue structures as compared to visible light. NIR imaging of 21 patients was performed and compared with computed tomography (CT) scans. Individual maxillary sinuses were scored on a scale from 0 to 2 based on their degree of aeration present on CT and similarly based on the NIR signal penetration into the maxilla on NIR images. Our results showed that air-filled and fluid/tissue-filled spaces can be reasonably distinguished by their differing NIR signal penetration patterns, with average NIR imaging scores for fluid-filled maxillary sinuses (0.93+/-0.78, n=29) significantly lower than those for normal maxillary sinuses (1.62+/-0.57, n=13) (p=0.003). NIR imaging of the sinuses is a simple, safe, and cost-effective modality that can potentially aid in the diagnosis of sinusitis. Long-term, significant device refinement and large clinical trials will be needed to determine the diagnostic accuracy of this technique.

    Chordomas are rare tumours arising from notochordal remnants. Classical chordomas are generally extradural and, despite benign histopathology, they typically destroy the clivus and surrounding bone structures. Intradural lesions are extremely rare and less than thirty cases of intracranial, exclusively intradural chordomas have been reported so far. The intracranial, intradural but extranotochordal location of chordoma is extremely unique. The authors present a case of chordoma in intracranial location that clinically mimics lateral sphenoid wing meningioma. A previously healthy 39-year-old man was admitted to our Department because of optic disc oedema without neurological deficits. Neuroimaging studies showed a large, contrast-enhanced tumour in the right frontotemporal region that was thought to be a pterional meningioma. The patient underwent successful removal of the tumour. Histopathological study revealed a typical pattern of chordoma, confirmed by immunohistochemical findings. Because of the tumour location the differentiation between chordoma and chordoid meningioma ought to be considered. Such cases, including the present one, may lead to the conclusion that embryonic notochordal remnants may be lost in different places, even away from the neuroaxis.

    As anorexia patients always go to the psychiatric clinic, little is concerned about the occurrence of sinus bradycardia in these patients for cardiologists and psychiatrists. The aim of this paper is to discuss the relationship between anorexia and sinus bradycardia, and the feature analysis, differential diagnosis and therapeutic principles of this type of sinus bradycardia. We report a case of sinus bradycardia in an anorexia patient with the clinical manifestations, laboratory exams, auxiliary exams, therapeutic methods, and her prognosis, who was admitted to Peking University Third Hospital recently. The patient was a 19-year-old female, who had the manifestation of anorexia. She lost obvious weight in a short time (about 15 kg in 6 months), and her body mass index was 14.8 kg/m(2). The patient felt apparent palpitation, chest depression and short breath, without dizziness, amaurosis or unconsciousness. Vitals on presentation were notable for hypotension, and bradycardia. The initial exam was significant for emaciation, but without lethargy or lower extremity edema. The electrocardiogram showed sinus bradycardia with her heart rate being 32 beats per minute. The laboratory work -up revealed her normal blood routine, electrolytes and liver function. But in her thyroid function test, the free thyroid (FT) hormones 3 was 0.91 ng/L (2.3-4.2 ng/L),and FT4 was 8.2 ng/L (8.9-18.0 ng/L), which were all lower; yet the thyroid stimulating hormone (TSH) was normal 1.48 IU/mL (0.55-4.78 IU/mL). Ultrasound revealed her normal thyroid. Anorexia is an eating disorder characterized by extremely low body weight, fear of gaining weight or distorted perception of body image, and amenorrhea. Anorexia patients who lose weight apparently in short time enhance the excitability of the parasympathetic nerve, and inhibit the sympathetic nerve which lead to the appearance of sinus bradycardia, and functional abnormalities of multiple systems such as hypothyroidism.

    Orbital complications categorised by Chandler are emergency. They need early diagnosis and agresive treatment. Stage and origin of orbital complications are identified by rhinoendoscopy, ophtalmologic examination and CT of orbite and paranasal sinuses. Periorbital cellulitis and early stage of orbital cellulitis can be treated conservatively with i. v. antibiotics. Monitoring of laboratory parameters and ophtalmologic symptoms is mandatory. Lack of improvement or worsening of symptoms within 24-48 hours and advanced stages of orbital complications are indicated for surgery. The purpose of the study is to evaluate epidemiology, clinical features and management of sinogenic orbital complications. Retrospective data of 8 patients with suspicion of orbital complication admited to hospital from 2008 to 2013 were evaluated. Patients were analyzed in terms of gender, age, CT findings, microbiology, clinical features, stage and treatment. Male and female were afected in rate 1,66:1. Most of patients were young adult in 3rd. and 4th. decade of life (62,5 %). Acute and chronic sinusitis were cause of orbital complication in the same rate. The most common origin of orbital complication was ethmoiditis (62,5 %), than maxillary (25 %) and frontal (12,5 %) sinusitis. Polysinusitis with affection of ethmoidal, maxillary and frontal sinuses (75 %) was usual CT finding. Staphylococcus epidermidis and Staphylococcus aureus were etiological agens in half of cases. Periorbital oedema (100 %), proptosis, chemosis (50 %), diplopia and glaucoma (12,5 %) were observed. Based on examinations, diagnosis of periorbital oedema/preseptal cellulitis was made in 3 (37,5 %), orbital cellulitis in 3 (37,5 %) and subperiosteal abscess in 2 cases (25 %). All patients underwent combined therapy - i. v. antibiotics and surgery within 24 hours. Eradication of disease from ostiomeatal complex (OMC), drainage of affected sinuses and drainage of subperiosteal abscess were done via fuctional endonasal

    Primary Ewing Sarcoma of the cranial bone is rare, contributing to only 1% of all Ewing Sarcomas. Primary cranial Ewing Sarcoma occurs most commonly in temporal bone followed by parietal and occipital bones. Sphenoid bone is less commonly involved. We report a case of Ewing Sarcoma of the sphenoid bone with intra-cranial extension in a 20-month-old boy. On CT scan a provisional diagnosis of rhabdomyosarcoma was made. Fine Needle Aspiration Cytology (FNAC) and histopathological examination of core needle biopsy showed small round cell tumour. On Immunohistochemistry (IHC), CD99 (MIC2) and FLI 1 were strongly positive and final diagnosis of Ewing Sarcoma was made. Considering the rarity of this unusual site, we report a case of primary Ewing Sarcoma arising in the sphenoid bone with erosion of adjacent bones and intra-cranial extension. PMID:28384876

    Maxillary sinusitis of odontogenic origin is a well-known condition in both the dental and otolaryngology communities. It occurs when the Schneiderian membrane is violated by conditions arising from dentoalveolar unit. This type of sinusitis differs in its pathophysiology, microbiology, diagnostics and management from sinusitis of other causes, therefore, failure to accurately identify a dental cause in these patients usually lead to persistent symptomatology and failure of medical and surgical therapies directed toward sinusitis. Unilateral recalcitrant disease associated with foul smelling drainage is a most common feature of odontogenic sinusitis. Also, high-resolution CT scans and cone-beam volumetric computed tomography can assist in identifying dental disease. Sometimes dental treatment alone is adequate to resolve the odontogenic sinusitis and sometimes concomitant or subsequent functional endoscopic sinus surgery or Caldwell-Luc operation is required. The aim of this article is to give a review of the most common causes, symptoms, diagnostic and treatment methods of odontogenic maxillary sinusitis. Search on Cochrane Library, PubMed and Science Direct data bases by key words resulted in 35 articles which met our criteria. It can be concluded that the incidence of odontogenic sinusitis is likely underreported in the available literature.

    Actinomycosis is a bacterial infection due to Actinomyces israelii, a gram-positive, anaerobic organism that normally affects the cervicofacial region. However, facial injury or trauma (i.e., dental procedures) can allow this bacteria to inhabit other regions. There have been rare reports of actinomycosis of the paranasal sinuses. We present a case of a 50-year-old female who originally presented with a suspected oroantral fistula who subsequently was found to have actinomycosis involving her right maxillary sinus. Additionally, the dental extraction site revealed no connection with the maxillary sinus. We discuss the diagnostic approach and management of this patient as it relates to the limited existing literature.

Trichosporon species as a cause for fungal sinusitis has been very rarely reported the world over. Here, we report a rare case of allergic fungal sinusitis caused by Trichosporon inkin in a 28-year-old immunocompetent woman. Bilateral nasal obstruction, nasal discharge and loss of smell were her presenting complaints. Diagnostic nasal endoscopy showed bilateral multiple polyps. Functional endoscopic sinus surgery was performed and many polyps were removed. Based on mycological and histopathological studies, the pathogen was identified as T. inkin.

    Extraordinary advancements in sequencing technology have made what was once a decade-long multi-institutional endeavor into a methodology with the potential for practical use in a clinical setting. We therefore set out to examine the clinical value of next-generation sequencing by enrolling patients with incurable or ambiguous tumors into the Personalized OncoGenomics initiative at the British Columbia Cancer Agency whereby whole genome and transcriptome analyses of tumor/normal tissue pairs are completed with the ultimate goal of directing therapeutics. First, we established that the sequencing, analysis, and communication with oncologists could be completed in less than 5 weeks. Second, we found that cancer diagnostics is an area that can greatly benefit from the comprehensiveness of a whole genome analysis. Here, we present a scenario in which a metastasized sphenoid mass, which was initially thought of as an undifferentiated squamous cell carcinoma, was rediagnosed as an SMARCB1-negative rhabdoid tumor based on the newly acquired finding of homozygous SMARCB1 deletion. The new diagnosis led to a change in chemotherapy and a complete nodal response in the patient. This study also provides additional insight into the mutational landscape of an adult SMARCB1-negative tumor that has not been explored at a whole genome and transcriptome level. PMID:24807916

    Extraordinary advancements in sequencing technology have made what was once a decade-long multi-institutional endeavor into a methodology with the potential for practical use in a clinical setting. We therefore set out to examine the clinical value of next-generation sequencing by enrolling patients with incurable or ambiguous tumors into the Personalized OncoGenomics initiative at the British Columbia Cancer Agency whereby whole genome and transcriptome analyses of tumor/normal tissue pairs are completed with the ultimate goal of directing therapeutics. First, we established that the sequencing, analysis, and communication with oncologists could be completed in less than 5 weeks. Second, we found that cancer diagnostics is an area that can greatly benefit from the comprehensiveness of a whole genome analysis. Here, we present a scenario in which a metastasized sphenoid mass, which was initially thought of as an undifferentiated squamous cell carcinoma, was rediagnosed as an SMARCB1-negative rhabdoid tumor based on the newly acquired finding of homozygous SMARCB1 deletion. The new diagnosis led to a change in chemotherapy and a complete nodal response in the patient. This study also provides additional insight into the mutational landscape of an adult SMARCB1-negative tumor that has not been explored at a whole genome and transcriptome level.

    Isolated unilateral abducens nerve palsy is usually due to ischemia, trauma or neoplasm. Dorello's canal is the space between the petrous apex and superolateral portion of the clivus, bound superiorly by Gruber's ligament. The abducens nerve travels with inferior petrosal sinus (IPS) though the Dorello's canal before entering the cavernous sinus. A 31-year-old man presented with neck pain, and binocular horizontal diplopia, worse looking towards left and at distance. He had a history of intravenous drug abuse but no history of hypertension or diabetes. On examination, he had complete left 6th nerve palsy with normal fundi, pupils, and other cranial nerves. Methicillin-resistant Staphylococcus aureus bacteremia was detected with naïve tricuspid valve endocarditis and multiple septic emboli to lungs with infarcts. His cerebrospinal fluid was normal. MRI of the brain was normal. MRV of head and neck showed thrombosis of the left internal jugular vein, left sigmoid sinus and left inferior petrosal sinus with normal cavernous sinus and no evidence of mastoiditis. He was treated with broad spectrum antibiotics. He was not anticoagulated for fear of pulmonary hemorrhage from pulmonary infarcts. Although cerebral venous sinus thrombosis commonly presents with elevated intracranial pressure, isolated ipsilateral 6th nerve palsy from its compression in Dorello's canal due to thrombosis of the ipsilateral inferior petrosal sinus is extremely rare. To our knowledge, only two patients have been reported with isolated abducens palsy due to IPS thrombosis; one caused by septic emboli and the other developed it during IPS cortisol level sampling.

    Introduction Whether mucosal cyst of maxillary sinus is contraindication for sinus floor augmentation surgery has been a controversial hot spot for years. Presentation of case This case aims to present the surgical procedure of sinus floor augmentation surgery with cyst (18.72 mm × 24.61 mm) in diabetic patient. And 6 months later, the cyst decreased in size. The authors elevated the sinus floor and cyst simultaneously. The surgery was carried out successfully without sinus membrane perforation and the alveolar ridge gained about 8 mm height. Six months later, the cyst decreased in size and osseointegration was observed. Discussion Interdisciplinary cooperation is encouraged to diagnose benign mucosal cyst. The isolation between sinus lumen and the grafted sub-sinus space is important. Graft contamination or dispersion into the sinus lumen should be avoided. The integrity of the sinus membrane and use of antibiotics are very important to prevent the occurrence of postoperative sinus infection Conclusion The authors conclude that sinus augmentation surgery could be done with mucosal cyst in diabetic patient.

    Maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. The majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. Conventional radiographs could not differentiate between inflammatory mucosal thickening, neoplasm, and hypoplasia of the sinus. Computed tomography (CT) and also cone beam computed tomography (CBCT) are the proper modalities to detect these conditions. In the present study, CBCT findings of three cases with maxillary sinus hypoplasia and aplasia are reported. PMID:25426156

    Aneurysms of the sinus of Valsalva are very uncommon, with an incidence ranging from 0.1 to 3.5% of all congenital heart defects. Very few cases have been reported in the literature that presented with involvement of two or more sinuses. We report a case of 27-year-old male with a history of exertional breathlessness of one-month duration. After complete evaluation using transesophageal echocardiography (TEE) and multiple detector computed tomography (MDCT) scanning, the patient was diagnosed to have large congenital unruptured sinus of Valsalva aneurysms involving both left and right coronary sinuses with extension into the interventricular septum. The patient also displayed second-degree heart block (Mobitz type 2) and biventricular dysfunction. The patient was managed successfully. We present the case with an aim to highlight the management challenges including intraoperative and postoperative complications that are associated with unruptured sinus of Valsalva aneurysms of ≥2 sinuses.

    Sinusitis is frequently associated with asthma. The diagnosis and management of patients with asthma associated with sinusitis are often challenging, though sometimes unsatisfactory. Detection and treatment of sinusitis in asthmatics may lead to a better control of asthma symptoms. Most of the studies regarding the relationship between sinusitis and asthma have been conducted in adults. The aim of the present study was to evaluate the presence of sinusal comorbidity in children with un-controlled asthma both clinically and through nasal endoscopy after the first 6 months of treatment. The present study included 294 consecutive asthmatic children (97 males, mean age 7.3 years). Asthma diagnosis, severity assessment and treatment were performed according to GINA guidelines. Twenty-one patients with non-controlled asthma presented with endoscopic features of sinusitis, but without any clinical sign or symptom. We defined such condition occult sinusitis. Not only overt sinusitis, but also occult sinusitis could be a significant comorbidity in asthmatic patients. For this reason, it may be beneficial to determine the presence of sinus inflammation in children with non-controlled asthma, even when they do not present clinical signs or symptoms of upper airways involvement.

    Periorbital soft tissue swelling may result due to primary orbital pathology or from adjacent facio-maxillary or sino-nasal inflammatory causes. Osteomyelitis of maxilla in the pediatric age group is a rare entity in this era of antibiotics. We present an 11-month-old female infant who was brought with peri-orbital selling and purulent nasal discharge. Computed Tomography showed erosions of the walls of maxillary sinus suggestive of osteomyelitis. Culture of sinus scraping showed Staphylococcus aureus growth and the child improved with intravenous cloxacillin therapy. This case is presented due to the rarity of its presentation in this age group and for awareness to consider this entity in children having fever and peri-orbital swelling. PMID:25191055

    Chronic invasive fungal sinusitis (CIFS) is a rare but potentially aggressive form of invasive fungal disease that occurs in immunocompetent patients. We report a case of CIFS in an otherwise healthy young adult associated with intranasal illicit drug abuse. The patient presented with nonhealing nasal septal and palatal perforations. Biopsy demonstrated invasive Aspergillus flavus requiring surgical debridement and extended intravenous antifungal therapy. Tissue necrosis and ulceration related to intranasal drug use should be recognized as a potential risk factor for invasive fungal sinusitis.

    A 35 year old primigravida presented a rare arrhythmia defined as persistent idiopathic sinus tachycardia, which appeared strongly symptomatic during the first weeks of pregnancy. Based on electrophysiological evaluation and pharmacological tests, we retained that the pathogenetic mechanism was due to enhanced automaticity in the sinus node, or in a near "atrial ectopic focus", as a result of a localized autonomic dysfunction. The maternal-foetal prognosis resulted extremely favorable thanks to antiarrhythmic drug association during the last six months of pregnancy.

    Lyme disease is the most prevalent tick-borne disease in the United States. It is caused by the spirochete Borrelia burgdorferi. Cardiac involvement is seen in 4% to 10% of patients with Lyme disease. The principal manifestation of Lyme carditis is self-limited conduction system disease, with predominant involvement of the atrioventricular node. On rare occasions, Lyme carditis patients present with other conduction system disorders such as bundle branch block, intraventricular conduction delay, and supraventricular or ventricular tachycardia. We report the unusual case of a 59-year-old man who presented with new-onset symptomatic sinus pauses one month after hiking in upstate New York. To our knowledge, this is the first case report from North America that describes the relationship between symptomatic sinus pause and Lyme carditis.

    Introduction Septic cavernous sinus thrombosis (CST) is a rare condition that can result in high mortality and morbidity rates if not treated immediately. CST may be aseptic or septic. Less common primary sites of infection include the tonsils, soft palate, middle ear, and orbit. Reported cases of middle ear infection are very rare, and response to treatment is poor. Case Presentation The present study is a case report of acute otitis media which led to septic cavernous sinus thrombosis in a 56-year-old woman in Bojnord city, North Khorasan, Iran. Conclusions Findings of laboratory tests and magnetic resonance imaging (MRI) confirmed the clinical diagnosis. Clinical-based medical care led to successful management of the patient with broad spectrum intravenous antibiotics that prevented serious complications. PMID:27781123

    The most common primary tumors of the frontal sinus are osteomas and inverted papillomas, although a variety of other tumors involving this space have been reported. With the advent of new surgical techniques and instrumentation, an endoscopic approach to this region has become feasible. The preoperative assessment and decision making must take into account the complexity of frontal sinus anatomy, tumor type, tumor location, and associated attachments. These procedures allow adequate visualization, tumor removal, and postoperative monitoring, and preserve fairly normal sinus function. Open techniques may also be required and should be in the surgeon's armamentarium.

    Breathing vitally serves body homeostasis. The prevalence of upper airway infections is often taken as an indicator of overall health status of a population living at a given time. In the present study we examined the unearthed remains of skulls from the XIII-XV century inhabitants searching for signs of maxillary sinusitis. Maxillary sinuses of the skulls of 92 individuals were inspected macroscopically and, if necessary, endoscopically. Osseous changes, including the pitting and abnormal spicule formation were present in 69 cases (75.0 %). It was found that, overall, dental infection was a major cause of maxillary sinusitis (18.8 %). Severe bone changes were observed in the adults' skulls, but were also present in the sinus walls of children's skulls. Post-inflammatory changes were manifest as remodeling and damage to the sinus walls. The results indicate that both children and adults of the Middle Ages suffered from chronic sinusitis. These observations confirm that the climate, environment, and lifestyle of the medieval populations contributed to the morbidity of the upper respiratory tract.

    Purpose. Radiography is important in forensic odontology for the identification of humans. The maxillary sinus is the largest of the paranasal sinuses and first to develop. Sinus radiography has been used for identification of skeletal remains and determination of gender. Hence, the aim and objectives of the present study were to establish a new method for gender determination using maxillary sinus index from lateral cephalometric radiographs and to establish the reliability of maxillary sinus for gender determination. Methods. A total of 50 adult digital lateral cephalometric radiographs (25 males and 25 females) were included in the study. The maxillary sinus analysis was performed on these radiographs using the height and width measurement tools of Sidexis XG software. Maxillary sinus index was calculated, discriminant function analysis performed, and discriminant equation derived for determination of gender. Results. The mean maxillary sinus height and width were found to be higher in males, whereas the maxillary sinus index was greater in females. The discriminant function analysis derived in the study was able to differentiate the sex groups with sensitivity of 68% and specificity of 76%. Conclusions. From the results of the present study, it may be concluded that morphometric analysis of maxillary sinus can be used as a reliable tool in gender determination. PMID:28373883

    Extraoral sinus tract often poses a diagnostic challenge to the clinician owing to its rare occurrence and absence of symptoms. The accurate diagnosis and comprehensive management are inevitable as the aetiology of such lesions is often masked and requires holistic approach. The present case report encompasses the management of an extraoral discharging sinus tract at the base of the right nostril in a chronic smoker. The lesion which was earlier diagnosed to be of nonodontogenic origin persisted even after erratic treatment modalities. Our investigations showed the aetiology of sinus tract to be odontogenic. Initially, a five-step program as recommended by the Agency for Health Care Research and Quality was used for smoking cessation followed by root canal therapy (RCT) and surgical management of the sinus tract. The patient has been under stringent follow-up and no reoccurrence has been noted. PMID:26649208

    The authors report 14 cases of Wegener granulomatosis in which one or more paranasal sinuses were obliterated by bone. The maxillary antra were involved in all cases, with the other sinuses being affected less frequently. These changes are thought to result from chronic bacterial sinusitis superimposed on the granulomatous vasculitic process. Computed tomography dramatically demonstrated the bone changes, consisting of a combination of sinus wall thickening and trabeculated new bone formation within the sinuses.

    Limited alveolar bone height prevents the placement of dental implants. Sinus floor elevation is an internal augmentation of the maxillary sinus that allows implants to be placed. The principle of this surgical procedure is the preparation of a 'top hinge door', that is raised together with the Schneiderian membrane in the cranial direction. The space which created under this lid is filled with a bone transplant. Autogenous bone is the standard transplant material, despite the fact that a second surgery site is necessary. Under certain circumstances bone substitutes can be used, with a longer healing phase. If sufficient alveolar bone height is available to secure implant stability, simultaneous implantation and sinus floor elevation are possible. Considering the significant anatomical variation in the region of the maxillary sinus, a sound knowledge of the anatomy is of great importance.

    Nosocomial pneumonia is a frequent infectious complication in ICU patients. All the patients with prolonged nasotracheal intubation presenting with nosocomial pneumonia according to Salata's criteria were examined for sinusitis in the prospective study. Diagnosis was confirmed via CT-scan views and transnasal sinus puncture. In eleven nasally intubated patients, CT-scan views showed air fluid levels and multiple sinus involvement. Bacteriological studies isolated the same gram negative bacilli in both sinus and bronchial aspirates. In four cases, a polymicrobial sinusitis was found with a single organism predominant. This predominant germ was always found in bronchial aspirate. Recovery from pneumonia was obtained only after sinus drainage. Treatment included removing the nasal tubes, or performing tracheostomy and systemic antibiotics. One patient required surgical maxillary sinus drainage after failure of medical management. The occurrence of nosocomial pneumonia in nasotracheally intubated patients should lead physicians to explore the paranasal sinuses. Sinus CT-scan views should be routinely obtained in the assessment of pulmonary sepsis in patients with prolonged nasotracheal intubation. Persistent or ignored nosocomial sinusitis in such circumstances could be a major source of treatment failure.

    PubMed

    Tieghi, Riccardo; Malagutti, Nicola; Valente, Luisa; Carnevali, Giulia; Clauser, Luigi C

    2017-01-31

    Silent Sinus Syndrome is defined as a painless spontaneous and progressive enophthalmos and hypoglobus with maxillary sinus hypoplasia and orbital floor resorption. It is caused by maxillary sinus atelectasis in a setting of ipsilateral chronic maxillary sinus hypoventilation. The syndrome was first described in 1964 by Montgomery, but the term "Silent Sinus Syndrome" was not coined until 1994 by Soparkar. The aetiology is still controversial: some authors postulate a basal hypoplastic sinus, other suggest an acquired process due to an obstruction of the ostium in the medium meatus. Silent Sinus Syndrome presents in the third to fifth decades of life, very rarely in childhood with no gender predilection and it is usually a unilateral disorder. The symptoms are not shown to be related to chronic sinuses disease. The clinical signs are: enophthalmos, hypoglobus, upper lid retraction secondary to dystopia of the globe, sinking of the eye and orbital asymmetry, deepened upper lid sulcus, disappearance of the palpebral fold line, lagophthalmos, vertical diplopia, malar depression, and facial asymmetry. Extraocular muscle function is generally preserved and usually there is no visual impairment. The diagnosis is confirmed by computed tomography scan of the orbits and paranasal sinuses. The treatment consists of orbital reconstruction and functional rehabilitation of the maxillary sinuses.

    2009-01-01

    Frontal sinus injuries may range from isolated anterior table fractures resulting in a simple aesthetic deformity to complex fractures involving the frontal recess, orbits, skull base, and intracranial contents. The risk of long-term morbidity can be significant. Optimal treatment strategies for the management of frontal sinus fractures remain controversial. However, it is critical to have a thorough understanding of frontal sinus anatomy as well as the current treatment strategies used to manage these injuries. A thorough physical exam and thin-cut, multiplanar (axial, coronal, and sagittal) computed tomography scan should be performed in all patients suspected of having a frontal sinus fracture. The most appropriate treatment strategy can be determined by assessing five anatomic parameters including the: frontal recess, anterior table integrity, posterior table integrity, dural integrity, and presence of a cerebrospinal fluid leak. A well thought out management strategy and meticulous surgical techniques are critical to success. The primary surgical goal is to provide a safe sinus while minimizing patient morbidity. This article offers an anatomically based treatment algorithm for the management of frontal sinus fractures and highlights the key steps to surgical repair. PMID:22110810

    The morphometric analysis of maxillary sinus was recently presented as a helpful instrument for sex determination. The aim of the present study was to examine the volume and surface of the fully dentate, partial, and complete edentulous maxillary sinus depending on the sex. Computed tomography data from 276 patients were imported in DICOM format via special virtual planning software, and surfaces (mm) and volumes (mm) of maxillary sinuses were measured. In sex-specific comparisons (women vs men), statistically significant differences for the mean maxillary sinus volume and surface were found between fully dentate (volume, 13,267.77 mm vs 16,623.17 mm, P < 0.0001; surface, 3480.05 mm vs 4100.83 mm, P < 0.0001) and partially edentulous (volume, 10,577.35 mm vs 14,608.10 mm, P = 0.0002; surface, 2980.11 mm vs 3797.42 mm, P < 0.0001) or complete edentulous sinuses (volume, 11,200.99 mm vs 15,382.29 mm, P < 0.0001; surface, 3118.32 mm vs 3877.25 mm, P < 0.0001). For males, the statistically different mean values were calculated between fully dentate and partially edentulous (volume, P = 0.0022; surface, P = 0.0048) maxillary sinuses. Between the sexes, no differences were only measured for female and male partially dentate fully edentulous sinuses (2 teeth missing) and between partially edentulous sinuses in women and men (1 teeth vs 2 teeth missing). With a corresponding software program, it is possible to analyze the maxillary sinus precisely. The dentition influences the volume and surface of the pneumatic maxillary sinus. Therefore, sex determination is possible by analysis of the maxillary sinus event through the increase in pneumatization.

To gain a better understanding of the characteristics of IA sinusitis in this population, we present a unique case of chronic IA sinusitis in an HIV-infected patient taking antiretroviral therapy and review the literature summarizing published cases of invasive aspergillosis of the paranasal (n = 41) and mastoid (n = 17) sinuses in HIV-infected individuals. Among these cases, only 4 were reported after 1999, and 98% of patients had acquired immune deficiency syndrome. Orbital invasion occurred in 54% of paranasal sinus cases, whereas intracranial invasion was reported in 53% of mastoid sinus cases. The overall mortality was 79%. We also discuss various clinical and immunologic factors that may play a role in the development of IA and consider the changing epidemiology of aspergillosis in the era of effective antiretroviral therapy.

    Objective Rapid maxillary expansion (RME) is used to expand the maxilla and increase arch perimeter; yet, there are few reports on its effects on the sphenoid bone. With cone-beam computed topography (CBCT), it is possible to visualize sphenoid bone changes. The purpose of this study was to investigate sphenoid bone changes observed in conjunction with RME treatments, using CBCT. Methods Sixty patients (34 women and 26 men, aged 11–17 years) underwent RME as part of their orthodontic treatment. Patients were randomly assigned to one of three groups: a tooth-anchored group, a bone-anchored group, or a control group. Initial CBCT scans were performed preceding the RME treatment (T1) and again directly after the completion of expansion (T2). Statistical analysis included ANOVA, descriptive statistics, and the intraclass correlation coefficient (ICC). Results The reliability of the landmark location was at least 0.783, and the largest ICC mean measurement error was 2.32 mm. With regard to distances, the largest change was 0.78 mm, which was not statistically significant (p > 0.05). Statistical significance was established in patient groups of the same sex and treatment type for the following distance measurements: right anterior lateral pterygoid plate to the right edge of the hypophyseal fossa (d2), anterior distance between the medial pterygoid plates (d4), and anterior distance between the left medial and lateral plates (d8). Conclusions In this study, there were no clinically significant changes in the sphenoid bone due to RME treatments regardless of sex or treatment type. PMID:27668190

    Primary Ewing's sarcoma of the skull is a very rare entity. We report MRI findings in a case of Ewing's sarcoma of the greater wing of sphenoid in a 4-year-old patient. Magnetic resonance imaging showed markedly heterogenous signal intensity with areas of haemorrhage and necrosis. It also demonstrated the exact extent of tumour due to its multiplanar capabilities and was, therefore, helpful in planning surgery.

    Computed tomography (CT) is now used extensively for the evaluation of orbital, facial, and intracranial infections. Nine patients are presented to illustrate the importance of detecting underlying and unsuspected sinusitis. Prompt treatment of the sinusitis is essential to minimize the morbidity and mortality associated with complications such as brain abscess, meningitis, orbital cellulitis, and osteomyelitis. A review of the literature documents the persistence of these complications despite the widespread use of antibiotic therapy. Recognition of the underlying sinusitis is now possible with CT if the region of the sinuses is included and bone-window settings are used during the examination of patients with orbital and intracranial infection.

    Sinus of Valsalva aneurysm accounts for only 1% of congenital cardiac anomalies. Sinus of Valsalva aneurysm can cause aortic insufficiency, coronary artery flow compromise, cardiac arrhythmia, or aneurysm rupture. Three-dimensional transesophageal echocardiography (3DTEE) represents an adjunctive tool to demonstrate the ruptured sinus of Valsalva with better delineation. We present an adult patient with rupture of noncoronary sinus of Valsalva aneurysm into the right atrium (RA). 3DTEE accurately delineated the site of rupture into the RA and showed the exact size and shape of the defect, which helped in the successful transcatheter closure of the defect with a duct occluder device.

    Endoscopic frontal sinus surgery has been proven to enable the treatment of most frontal sinus pathologies but may be challenging for the surgeon in regard to the variable frontal sinus anatomy. Frontal sinus drainage identification and frontal sinus visualization are an essential part of successful frontal sinus surgery. We demonstrate a novel modular mini-endoscopic system for frontal sinus surgery. Fifty-two patients (37 male, 15 female) with a chronic rhino-sinusitis were enrolled. In this study, all patients were subjected to standard endonasal endoscopic sinus surgery with use of the fibre optic endoscope "Sinus View" (1.1 mm diameter, 10,000 pixels, irrigation channel and additional working channel) accessing the frontal sinus. A frontal sinus drainage type I in 38 cases, a frontal sinus drainage type IIa in 9 cases and a frontal sinus drainage type IIb in 5 cases according to Draf were performed. The modular mini-endoscopic system "Sinus view" was used to identify frontal sinus drainage in ten patients before ethmoidectomy and in the remaining patients (N = 42) after ethmoidectomy. Visualization of the frontal sinus drainage or the frontal sinus itself was easily carried out after irrigation. A clear identification of the frontal sinus by illumination was achieved in all cases. In addition the working channel of the endoscope was successfully used to perform visualized balloon dilatation at the frontal sinus drainage or for biopsy. The endonasal visualization of the frontal sinus drainage and frontal sinus itself is facilitated by also using a modular mini-endoscope with the option to use the working channel of the endoscope for biopsy or balloon dilatation.

    Background: Individual identification is a subtle concept and often one of the most important priorities in mass disasters, road accidents, air crashes, fires, and even in the investigation of criminal cases. Matching specific features detected on the cadaver with data recorded during the life of an individual is an important aspect in forensics, and can be performed by fingerprint analysis, deoxyribonucleic acid matching, anthropological methods, radiological methods and other techniques which can facilitate age and sex identification. Sinus radiography is one such method that has been used for determination of the sex of an individual. Hence, an attempt is being made to use the different dimensions of the maxillary sinus in the determination of sex using coronal and axial sections of plain computed tomography (CT) scan. Materials and Methods: A total of 30 patients including 17 male and 13 female, visiting the Outpatient Department of the Mamata General Hospital were included as the study subjects. The dimensions of right and left maxillary sinuses of 30 subjects from plain CT were measured using SYNGO software and statistical analysis was done. Results: Sex determination using height, length, width, and volume of the maxillary sinus on both sides showed statistically significant results with a higher percentage of sexual dimorphism in the case of volume. Conclusion: Volume of the right maxillary sinus can be used as accurate diagnostic parameter for sex determination. PMID:26005308

    Macroprolactinomas may behave invasively and infiltrate the skull base, causing a subsequent thinning that can also lead to a bone defect and a direct route of entry for pathogens. We describe the case of a 34-year-old male admitted to hospital with fever (38°C), headache, stiffness in the neck, diplopia and neurological impairment. Brain magnetic resonance imaging showed two bilateral abscesses in the fronto-parietal areas with intracranial venous sinus thrombosis and a pituitary adenoma that extended from the suprasellar region, eroding the sellar floor into the sphenoid sinus. Laboratory hormone measurements showed increased levels of prolactin and low levels of FSH, LH and testosterone. The patient received antibiotic treatment and surgery was performed. The patient developed central deafness as a neurological deficit. It is advisable to include pituitary adenoma in the differential diagnosis of meningitis even though its onset as intracranial abscess and rectus sinus thrombosis is extremely rare.

    Ectopic pituitary adenomas usually occur within sphenoid sinus or nasopharynx, and seldom within the clivus. There is only a single reported example of ectopic adenoma with clinical apoplexy, albeit not from clivus. We report a 78-year-old male with known prostate carcinoma admitted with acute onset of blurred vision, suggestive of apoplexy. Work-up revealed unilateral cranial nerve VI palsy and neuroimaging showed a mass confined to the clivus; sellar region was normal. Preoperative considerations included chordoma, chondrosarcoma, or metastatic prostate carcinoma to bone. Resection was via endoscopic transsphenoidal approach to the clivus. An ectopic null cell pituitary adenoma with bland infarction was identified as the cause of the patient's clinical apoplexy. No antecedent precipitating factors for apoplexy were present; specifically the patient had not received leuprolide preoperatively, a known precipitant of pituitary apoplexy in prostate cancer patients who receive drug. We review the literature on ectopic clival pituitary adenomas, apoplexy in ectopic adenomas, and the link between apoplexy and leuprolide usage.

  13. Rare and massive odontogenic parakeratotic cyst treated by endoscopic sinus surgery: a case report

    PubMed Central

    2014-01-01

    Introduction Keratocystic odontogenic tumors are benign neoplasms of odontogenic origin with a potential for aggressive and infiltrative behavior. Many different treatments for this type of lesion have been reported. However, no common consensus has emerged to date regarding the most effective therapeutic approach. Cases of maxillary sinus giant keratocystic odontogenic tumors completely excised by enucleation or marsupialization via endoscopic sinus surgery are extremely rare, and, to the best of our knowledge, only one case has been described in the literature since 2005. Case presentation We report a case of a 24-year-old Italian man who came to our department with maxillary sinus region swelling, pain and left nasal obstruction. A massive keratocystic odontogenic tumor involving the right maxillary sinus and causing focal erosions of the bony walls was diagnosed. The keratocystic odontogenic tumor was removed as much as possible by a transnasal approach using endoscopic sinus surgery, which produced optimal surgical and prognostic outcomes. Follow-up is reported for an 8-year period. Conclusion Conservative management in this case demonstrated good therapeutic efficacy with a low risk of recurrence. For injuries involving the maxillary sinus, the possibility of decompression or marsupialization by endoscopic sinus surgery should always be considered because it demonstrated the potential to lead to excellent results even after 8 years of follow-up in our patient. To our knowledge, no case report has described follow-up longer than 8 years for a maxillary sinus keratocystic odontogenic tumor treated with endoscopic sinus surgery. PMID:25193270

  14. Human paranasal sinuses and selective brain cooling: a ventilation system activated by yawning?

    PubMed

    Gallup, Andrew C; Hack, Gary D

    2011-12-01

    The function of the paranasal sinuses has been a controversial subject since the time of Galen, with many different theories advanced about their biological significance. For one, the paranasal sinuses have been regarded as warmers of respiratory air, when in actuality these structures appear to function in cooling the blood. In fact, human paranasal sinuses have been shown to have higher volumes in individuals living in warmer climates, and thus may be considered radiators of the brain. The literature suggests that the transfer of cool venous blood from the paranasal sinuses to the dura mater may provide a mechanism for the convection process of cooling produced by the evaporation of mucus within human sinuses. In turn, the dura mater may transmit these temperature changes, initiated by the cool venous blood from the heat-dissipating surfaces of the sinuses, to the cerebrospinal fluid compartments. Furthermore, it has recently been demonstrated in cadaveric dissections that the thin bony posterior wall of the maxillary sinus serves as an origin for both medial and lateral pterygoid muscle segments, an anatomic finding that had been previously underappreciated in the literature. The present authors hypothesize that the thin posterior wall of the maxillary sinus may flex during yawning, operating like a bellows pump, actively ventilating the sinus system, and thus facilitating brain cooling. Such a powered ventilation system has not previously been described in humans, although an analogous system has been reported in birds.

    Extrapulmonary tuberculosis is not rare and occurs mainly in the head and neck region. Cervical tuberculous lymphadenopathy is the most common form of extrapulmonary tuberculosis. Sinonasal tuberculosis is known to occur very rarely due to the protective functions of sinonasal mucosa. Although some signs of sinonasal tuberculosis may be present, such as associated facial abscesses, the symptoms and signs are usually nonspecific. Clinical suspicion is important for timely diagnosis and proper management of sinonasal tuberculosis due to its rarity and nonspecific clinical presentation. We report a case of tuberculosis confined to the unilateral maxillary sinus that was first misdiagnosed as recurrent rhinosinusitis after endoscopic sinus surgery.

    Objective: To evaluate the treatment effects of preoperative long-acting somatostatin analogue (SSA) combined trans-sphenoidal endoscopic surgery for patients with growth hormone (GH)-secreting pituitary macroadenomas. Methods: Retrospective analysis was carried out on 20 patients with GH-secreting pituitary macroadenomas who were treated with preoperative SSA and trans-sphenoidal endoscopic surgery in our apartment from January 2010 to January 2016. We also selected 20 patients with only trans-sphenoidal endoscopic surgery treatment and 20 patients with preoperative SSA and non-trans-sphenoidal endoscopic surgery treatment. The changes of tumor imaging, endocrine and blood pressure before and after treatment were analysed. Results: The Gross total resection (GTR) rate of invasive GH-secreting pituitary macroadenomas of preoperative SSA combined trans-sphenoidal endoscopic surgery group (8/13) were higher than that if only trans-sphenoidal endoscopic surgery group (4/16) and preoperative SSA combined non endoscopic surgery group (1/8) (P<0.05). Meanwhile, preoperative SSA combined trans-sphenoidal endoscopic surgery group had significantly improved the GH levels, blood glucose, lipid metabolism and blood pressure levels (P<0.05). Conclusion: The trans-sphenoidal endoscopic surgery on patients with GH-secreting pituitary macroadenomas has a significant improvement on GH levels, blood glucose, lipid metabolism and blood pressure levels. Through the treatment of preoperative long-acting SSA, the gross total resection rate is higher than other two groups.

    The cholesterol granuloma is well known in the middle ear, in the mastoid antrum and the air cells of temporal bone, mostly related to a chronic infectious process. There are other localizations such as the pleura, lung, pericardium, kidneys, arterial wall, nerves, brain, testicles, lymphatic ganglion and in the paranasals sinuses. Its localization in the mediofacial area is very unfrequent, having only been described 44 cases up to the year 2002. We present a 42 year-old patient, who required surgical treatment because of a increase in the volume of area her left facial of one month's old. It resulted to be secundary to an expansion of the maxilar sinus, such as seen on the computerized tomography carried out on the patient. The diagnosis was cholesterol granuloma, performed, through the anatomo-pathology study. We review the litterature on this subject and analyse the possible etiologic cause of this lesion, its clinic, diagnostic methodology and treatment.

    Alveolar rhabdomyosarcoma (RMS) is a primitive, malignant, round cell neoplasm derived from mesenchymal tissue that exhibits partial skeletal muscle differentiation. We describe a rare case of alveolar RMS of ethmoid sinus, recurring as an orbital mass. A 23-year-old man with the chief complaint of anosmia and mild proptosis was diagnosed with RMS of the left ethmoid sinus and orbit following an endoscopic biopsy of the mass. He was treated with chemotherapy and radiotherapy. At 12 months after diagnosis, while still on maintenance chemotherapy, he presented to our eye hospital with a large medial canthal mass and lateral globe displacement. Orbital computed tomography revealed an extraconal mass in the medial orbit of the left eye, extending posteriorly and compressing the medial rectus muscle. Notably, the ethmoid sinus was clear. Incisional biopsy was performed and the recurrence of alveolar RMS was confirmed. Alveolar RMS of the ethmoid sinus may recur as an orbital mass, even if the sinus where it originated is clear at the time of recurrence. PMID:27190854

    OBJECTIVE: To report the uncommon association between neurofibromatosis type 1 (NF1) and unroofed coronary sinus. CASE DESCRIPTION: Girl with four years and six months old who was hospitalized for heart surgery. The cardiac problem was discovered at four months of life. On physical examination, the patient presented several café-au-lait spots in the trunk and the limbs and freckling of the axillary and groin regions. Her father had similar skin findings, suggesting the NF1 diagnosis. The cardiac evaluation by echocardiography disclosed an atrial septal defect of unroofed coronary sinus type. This cardiac finding was confirmed at surgery. The procedure consisted of the atrial septal defect repair with autologous pericardium. COMMENTS: NF1 is a common autosomal dominant disorder caused by mutations in the NF1 gene. Among the NF1 findings, congenital heart defects are considered unusual. In the literature review, there was no association between NF1 and unroofed coronary sinus, which is a rare cardiac malformation, characterized by a communication between the coronary sinus and the left atrium, resultant from the partial or total absence of the coronary sinus roof. It represents less than 1% of atrial septal defect cases. More reports are important to determine if this association is real or merely casual, since NF1 is a common condition. PMID:24473962

    Background: The superior petrosal vein, one of the most constant and largest drainage pathways in the posterior fossa, may result in complications if occluded. This study calls attention to a unique variant in which the superior petrosal veins and sinus were absent unilaterally, and the venous drainage was through the galenic and tentorial drainage groups. Methods: This study examines one venogram and another anatomic specimen in which the superior petrosal vein and sinus were absent. Results: The superior petrosal veins, described as 1–3 bridging veins, emptying into the superior petrosal sinus, are the major drainage pathways of the petrosal group of posterior fossa veins. In the cases presented, the superior petrosal vein and sinus were absent and venous drainage was through the galenic and tentorial groups, including the lateral mesencephalic or bridging vein on the tentorial cerebellar surface. Conclusions: In cases in which the superior petrosal sinus and veins are absent, care should be directed to preserving the collateral drainage through the galenic and tentorial tributaries. Although surgical strategies for intraoperative management and preservation of venous structures are still controversial, knowledge of the possible anatomical variations is considered to be essential to improve surgical outcomes.

    The objective of the present study was to estimate the clinical efficacy of local antibacterial therapy in the children presenting with sinusitis. The study included a total of 104 patients allocated to 2 groups. In one of them, the patients underwent therapeutic and diagnostic punctures of the maxillary sinuses to obtain the material for subsequent microbiological analysis and to administer antibiotics into the sinuses. The results of the study give evidence that local application of antibacterial agents in combination with mucolytic drugs is at least as efficient for the treatment of acute maxillary sinusitis as the traditional methods for the management of the same conditions with the use of systemic antibiotics. The study confirmed the expediency of using the puncture technique for the treatment of patients with acute inflammatory process in maxillary sinuses.

    The purpose of this paper is to inform the ophthalmologist about the occurrence of ophthalmological complications after functional endoscopic sinus surgery (FESS). Due to the close anatomical relationship between the paranasal sinuses and the orbit, involvement and/or injury of the orbit from processes primarily located in the paranasal sinuses, may occur. The orbit, the extra-ocular muscles, the optic nerve and the lacrimal drainage system can be damaged during FESS. The risk of injury is correlated to the anatomical variations, the history of previous surgery, the extent and the gravity of the disease and the skill of the surgeon. We hereby present three cases, each showing a different ophthalmologic complication after FESS.

    Congenital dermal sinuses are tubular tracts which communicate the skin with deeper structures. It is a manifestation of defective separation of the ectoderm and neuroderm. The incidence is 1/2500-3000 births alive. Almost 10 % of congenital dermal sinuses are localized in the occipitocervical region. They are usually asymptomatic, unless an infectious process is concurrent (meningitis, abscess). We are presenting the case of a 12 months girl with unnoticed cutaneous stigmata in the occipital region, who was admitted with a meningeal syndrome and secondary neurological impairment. She had a cerebellar abscess and was treated with decompression by puncture of the abscess and antibiotics. When infection was resolved, congenital dermal sinus was excised. Process solves without morbidity. We reviewed the clinical and therapeutic features in cases reported previously in the literature.

    The present paper describes two distinct morphological features of ovine interdigital sinus, which were examined by means of scanning electron microscopy. In the sweat glandular component, acini with epithelial cells exhibiting a paved appearance and apocrine secretion were observed. In the same gland, other acini with cells exhibiting different luminal surfaces and simultaneous apocrine and merocrine secretion were recorded. The numerous hairs embedded within the waxy material of the sinus exhibited two types. The first type, with a round profile, had a special leaflet structure on the tip, whereas the second type had a convex profile. The comparative differences and probable functional relations of these integumentary structures are discussed. The mixed picture of the epithelial cells of the sweat glands suggests the release of different products. The hair microstructure correlated with the mechanism of hold and release of the secretory material of the interdigital sinus.

    Nasal septal abscess is a rare complication of acute sinusitis in children. We report the case of a 9-year-old girl who presented at the emergency unit with a bilateral eyelid edema evolving over 2 days, associated with bilateral rhinorrhea and nasal obstruction. Clinical examination found a tumefied nasal septum and nasal obstruction. A computed tomography scan of the nose and paranasal sinuses showed pansinusitis with an abscess of the nasal septum. Treatment consisted in the evacuation of the abscess associated with a triple antibiotic therapy. Progression was favorable. Acute sinusitis is seldom complicated by an abscess of the nasal septum, and very few cases are reported in the literature. Early diagnosis and treatment can avoid complications, which engage not only the functional but also the vital prognosis.

    Infected lateral cervical cysts in newborn are rare. We present the case of a baby born at 41 weeks of gestation. At day 3, persistent cyanosis was noted, and a mass appeared in the left cervical region next to the sternocleidomastoid muscle. No cutaneous sinus was visible. Ultrasound imaging showed no sign of blood flow within the mass and no septae. The mass extended down to the aortic arch and pushed the trachea to the right. A cervical lymphangioma was first suspected. Puncture of the mass evacuated 80 mL of pus, and a drain was put in place. Opacification through the drain showed a tract originating from the left pyriform fossa. Preoperative laryngoscopy and catheterization of the fistula tract confirmed the diagnosis. The cyst was totally excised up to the sinus with the assistance of a guidewire inserted orally through a rigid laryngoscope. This is a rare case of an infected pyriform sinus cyst in the neonatal period.

    The East African Early Miocene apes, or proconsulids, have often been considered to be among the earliest members of the Hominoidea, as defined by the divergence of the Cercopithecoidea, but this hypothesis is only weakly supported by available fossil evidence. The ethmofrontal sinus is one of a few morphological features that may link proconsulids with later hominoids. Here we present direct evidence of an ethmofrontal sinus in an early Oligocene stem catarrhine, Aegyptopithecus zeuxis. The presence of this sinus in Aegyptopithecus suggests that its presence in proconsulids is most likely to be a retained primitive condition. The morphological evidence bearing on proconsulids' purported hominoid affinities is further weakened by this conclusion, and alternative phylogenetic possibilities, such as the placement of proconsulids as stem catarrhines are considered more likely.

Here we present direct evidence of an ethmofrontal sinus in an early Oligocene stem catarrhine, Aegyptopithecus zeuxis. The presence of this sinus in Aegyptopithecus suggests that its presence in proconsulids is most likely to be a retained primitive condition. The morphological evidence bearing on proconsulids' purported hominoid affinities is further weakened by this conclusion, and alternative phylogenetic possibilities, such as the placement of proconsulids as stem catarrhines are considered more likely.

  12. Anatomical aspects of sinus floor elevations.

    Inadequate bone height in the lateral part of the maxilla forms a contra-indication for implant surgery. This condition can be treated with an internal augmentation of the maxillary sinus floor. This sinus floor elevation, formerly called sinus lifting, consists of a surgical procedure in which a top hinge door in the lateral maxillary sinus wall is prepared and internally rotated to a horizontal position. The new elevated sinus floor, together with the inner maxillary mucosa, will create a space that can be filled with graft material. Sinus lift procedures depend greatly on fragile structures and anatomical variations. The variety of anatomical modalities in shape of the inner aspect of the maxillary sinus defines the surgical approach. Conditions such as sinus floor convolutions, sinus septum, transient mucosa swelling and narrow sinus may form a (usually relative) contra-indication for sinus floor elevation. Absolute contra-indications are maxillary sinus diseases (tumors) and destructive former sinus surgery (like the Caldwell-Luc operation). The lateral sinus wall is usually a thin bone plate, which is easily penetrated with rotating or sharp instruments. The fragile Schneiderian membrane plays an important role for the containment of the bonegraft. The surgical procedure of preparing the trap door and luxating it, together with the preparation of the sinus mucosa, may cause a mucosa tear. Usually, when these perforations are not too large, they will fold together when turning the trap door inward and upward, or they can be glued with a fibrin sealant, or they can be covered with a resorbable membrane. If the perforation is too large, a cortico-spongious block graft can be considered. However, in most cases the sinus floor elevation will be deleted. Perforations may also occur due to irregularities in the sinus floor or even due to immediate contact of sinus mucosa with oral mucosa. Obstruction of the antro-nasal foramen is, due to its high location, not a

    Two young patients presented with generalised lymphadenopathy, otorrhoea, otitis, and rash. Over the next few years chronically discharging sinuses began to form over enlarged nodes and histological appearances were typical of histiocytosis X. In neither case were micro-organisms isolated from the lesions, and in both patients healing occurred with immunosuppressive agents. Chronic dermal sinus formation secondary to lymph node disease has never before been recorded as a manifestation of histiocytosis X. Histiocytosis X should therefore be considered in the differential diagnosis of "suppurative" lymphadenopathy so that appropriate treatment may be given without delay. Images Case 1 PMID:3084014

    Sphenoid wing dysplasia is a defining feature of neurofibromatosis type 1 (NF1). This defect of the skull base can be associated with pulsating exophthalmos. This report describes the successful reconstruction of a dysplastic sphenoid wing in an NF1 patient using lateral orbitotomy as a scarcely visible and sufficiently extendable approach. An intraoperative computed cone-beam computed tomography system (3D C-arm system) was used as a prompt and feasible technique to check the positioning of the titanium mesh in an anatomic region that is sensitive to mechanical stress.

    Two patients with mild cognitive impairment underwent C-PiB and F-FDG brain PET. Both patients had previously gone through a contrast-enhanced MRI scan that revealed extra-axial tumors next to the sphenoid wing, suggestive of meningiomas. C-PiB PET images showed a highly increased uptake by the extra-axial masses. These 2 cases represent 1.2% of our C-PiB population (n = 163). No meningioma was found with negative C-PiB uptake. The F-FDG concentration was not increased within the lesions. C-PiB could be used as a meningioma marker.

    Paranasal sinusitis is a condition that is treated by a General Practitioner and in case it fails it requires specialistic therapy. In most cases the inflammation is connected with nasal mucosa infection. However, in older children and adolescents sinusitis caused by spreading of tooth and gingiva inflammatory process can be an essential therapeutic and diagnostic problem. It is most often connected with periapical lesions, complications following dental procedures and oroantral fistula inflammation. Inflammatory process originally concerns maxillary sinus, however, it often undergoes generalization and it affects all or most of sinuses unilaterally or bilaterally. In microbiology of odontogenic sinusitis the dominant bacteria are the bacteria typical for peridental lesions (Streptococcus sanguis, Streptococcus salivarius, Streptococcus mutans and anaerobic bacteria). Odontogenic sinusitis frequently causes life threatening complications that require heroic drug and surgical treatment. Therapeutic and diagnostic problems are presented in case studies of 5 children aged from 10 to 17, who are treated in Children's Otolaryngology, Audiology and Phoniatrics Clinic in Łódź. There seems to be the need to emphasize the importance of thorough examination of oral cavity in all the children suffering from sinusitis, especially unilateral sinusitis. It is so essential on account of the gravity of the problem and serious complications that accompany the conditions.

    Frontal sinus pattern matching is a useful means of forensic identification. By the use of radiographs forensic scientists have recognized that there are diverse anatomical variations in the structure of the frontal sinus. Radiographs are a diagnostic tool, widely used in dental practices, hospitals and other health disciplines. Most health institutions possess the facility to store radiographs over long periods of time. Frontal sinus pattern matching technique can be applied in cases where ante mortem frontal sinus radiographs are available and dental matching cannot be carried out. Frontal sinus pattern matching technique may also be used to corroborate identifications based on other techniques such as fingerprints, teeth, or circumstantial evidence. The present study was carried out to assess the effectiveness of using the radiographic image of the frontal sinus for personal identification in studied population group. The results concluded that the appearance of the radiographic image of the frontal sinus is unique for each individual. On this evidence it is proposed that frontal sinus pattern matching can be used for personal identification when other methods have failed.

    At least one additional cardiac lesion was present in 18 consecutive patients with ruptured aneurysms of the sinuses of Valsalva who were investigated between 1956 and 1973 at the University of Alberta Hospital. Clinical diagnosis was made in 78% (14/18) of the patients. Confirmation at cardiac catheterization, operation or autopsy was obtained in all but one. The main sites of rupture were the right ventricle (seven cases), right atrium (five) and left ventricle (five). Fifty percent (9/18) are alive and well following prompt operative repair, an average of 8.2 years later (range, six months to 15 years). Replacement of the aortic valve was associated with a high mortality (50% early, 13% late, total 63%) which could be explained by the higher operative risk in this group of very ill patients. Eight patients (44.4%) had had bacterial endocarditis prior to presentation and this may have played a significant role in the rupture of the sinus of Valsalva aneurysm.

    The posterior maxillary segment frequently exhibits insufficient bone mass to support dental implants. Sinus floor augmentation enables implant placement in the posterior maxilla. This case series included ten sites, in which sinus floor elevation was done using sinus lift balloon system followed by augmentation utilizing irradiated cancellous bone allograft. Postoperative radiographic assessment of vertical bone gain was done at 3 and 6 months follow-up period. The mean initial and final bone height were 6.16 and 10.50 mm, respectively, with a mean increase of 4.34 mm at 6 months being observed with nil complication. The presented technique might represent a viable alternative for sinus elevation in posterior atrophied maxilla. Irradiated cancellous bone allograft can be advocated as an ideal bone graft material for sinus augmentation procedures. PMID:28298833

    Summary Treatment of cavernous sinus dural arteriovenous fistula (CSDAVF) may be challenging. We describe a patient who had presented with progressive ocular symptoms due to CSDAVF requiring urgent interventional therapy. Initial attempts to embolize the fistula utilizing a transvenous approach through the inferior petrosal sinus failed because of difficult anatomy. Successful occlusion of the fistula was subsequently achieved with injection of ethylene vinyl alcohol copolymer, Onyx (EV3 Neurovascular, Irvine, CA, USA), via direct percutaneous puncture of the cavernous sinus through the superior orbital fissure. A brief period of asystole during the initial injection of Onyx may be the result of the trigeminocardiac reflex. PMID:20465896

    Paranasal sinuses are some of the most poorly understood features of mammalian cranial anatomy. They are highly variable in presence and form among species, but their function is not well understood. The best-supported explanations for the function of sinuses is that they opportunistically fill mechanically unnecessary space, but that in some cases, sinuses in combination with the configuration of the frontal bone may improve skull performance by increasing skull strength and dissipating stresses more evenly. We used CT technology to investigate patterns in frontal sinus size and shape disparity among three families of carnivores: Canidae, Felidae, and Hyaenidae. We provide some of the first quantitative data on sinus morphology for these three families, and employ a novel method to quantify the relationship between three-dimensional sinus shape and skull shape. As expected, frontal sinus size and shape were more strongly correlated with frontal bone size and shape than with the morphology of the skull as a whole. However, sinus morphology was also related to allometric differences among families that are linked to biomechanical function. Our results support the hypothesis that frontal sinuses most often opportunistically fill space that is mechanically unnecessary, and they can facilitate cranial shape changes that reduce stress during feeding. Moreover, we suggest that the ability to form frontal sinuses allows species to modify skull function without compromising the performance of more functionally constrained regions such as the nasal chamber (heat/water conservation, olfaction), and braincase (housing the brain and sensory structures).

    2014-01-01

    Background Dermoid sinus is an uncommon epithelial-lined fistula that may be associated with vertebral malformations. In humans, Klippel-Feil syndrome (KFS) is a rare condition characterized by congenital cervical vertebral fusion and may be associated with other developmental defects, including dermoid sinus. The present case report describes an adult Dachshund with cervical and cranial thoracic vertebral malformations as well as thoracic limb malformations resembling KFS with a concurrent type IV dermoid sinus. Case presentation A 1.5 year-old Dachshund with congenital thoracic limbs deformities and cervical-thoracic vertebral malformations presented with cervical hyperesthesia, rigidity of the cervical musculature and tetraparesis. Neurologic, radiographic, and computed tomography (CT) (2D, 3D, CT fistulography) examinations revealed skeletal anomalies, a dermoid sinus in the cranial thoracic region and epidural gas within the vertebral canal. Surgical resection and histopathological evaluation of the sinus tract were performed and confirmed a type IV dermoid sinus. The clinical signs progressively recovered postoperatively, and no recurrent signs were observed after 6 months of follow-up. Conclusions Cervical vertebral malformations associated with limbs anomalies have not been reported in dogs and may represent a condition similar to KFS in humans. KFS can occur concurrently with other congenital conditions including dermoid sinus and should be included among the complex congenital anomalies described in dogs. PMID:24593884

    The blood supply to both the lateral wall of the maxillary sinus and the overlying membrane originates from the posterosuperior alveolar artery (PSAA) and the infraorbital artery. The purpose of the present study was to evaluate the anatomic characteristics of the PSAA in a large number of subjects of the Lebanese population. Images of 696 sinuses were analyzed using cone beam computed tomography (CT). Coronal, axial, and sagittal CT images were evaluated for the presence of an osseous canal in the lateral wall of the sinus, and the prevalence, position, and location of the canal were studied and presented.

    Purpose: To investigate the clinical features, prognostic factors, and toxicity of treatment for unresectable carcinomas of the nasal cavity and paranasal sinus (NCPS) treated with proton beam therapy (PBT). Methods and Materials: Seventeen patients (13 men, 4 women) with unresectable carcinomas of the NCPS who underwent PBT at University of Tsukuba between 2001 and 2007 were analyzed. The patients' median age was 62 years (range, 30-83 years). The tumors were located in the nasal cavity in 3 patients, the frontal sinus in 1, the ethmoid sinus in 9, and the maxillary sinus in 4. The clinical stage was Stage IVA in 5 cases, IVB in 10, and recurrent in 2. The tumors were deemed unresectable for medical reasons in 16 patients and because of refusal at a previous hospital 4 months earlier in 1 patient. All the patients received PBT irradiation dose of 22-82.5 GyE and a total of 72.4-89.6 GyE over 30-64 fractions (median 78 GyE over 36 fractions) with X-ray, with attention not exceeding the delivery of 50 GyE to the optic chiasm and brainstem. Results: The overall survival rate was 47.1% at 2 years and 15.7% at 5 years, and the local control rate was 35.0% at 2 years and 17.5% at 5 years. Invasion of the frontal or sphenoid sinus was a prognostic factor for overall survival or local control. Late toxicity of more than Grade 3 was found in 2 patients (brain necrosis in 1 and ipsilateral blindness in 1); however, no mortal adverse effects were observed. Conclusion: Proton beam therapy enabled a reduced irradiation dose to the optic chiasm and brainstem, enabling the safe treatment of unresectable carcinomas in the NCPS. Superior or posterior extension of the tumor influenced patient outcome.

    In this manuscript, we present a rare case report of giant complex odontoma in the maxillary sinus, where the applied therapy included complete excision of the lesion with a conservative approach. Odontomas are also called benign growth abnormalities or hamartomas. They represent a more common type of odontogenic tumor and are related to various disorders such as bad dental placements, expansion, increased volumetric bone, and no eruption of permanent teeth. Usually they have an asymptomatic evolutionary course. The etiologic factors, although obscure, are related to local trauma, infection, and genetic factor. The structural composition of an odontoma consists of mature dental tissues. Odontomas can be differentiated according to their anatomical presentations: Compound odontoma-clusters of several denticles and complex odontoma-well defined tumefaction mass. The diagnosis can be performed by radiographic examination. PMID:26389051

    A 41-year-old female with a history of uterine cancer and Celiac and Raynaud's Disease presented to our institution with frequent migraines and nasal congestion. She underwent functional endoscopic sinus surgery (FESS) and experienced acute unilateral vision loss postoperatively. Rapid recognition of the etiology and effective treatment are paramount given the permanent and irreversible vision loss that can result. Arterial vasospasm following FESS is rare. Patients with autoimmune diseases have perhaps an increased risk for vasospasm secondary to an increased vasoreactive profile. We present the first documented case of nitroglycerin sublingual therapy to successfully treat ophthalmic artery vasospasm following FESS. Nitroglycerin sublingual therapy is a promising treatment for ophthalmic vasospasm secondary to its ability to cross the blood-ocular barrier, its rapid onset of action, and its ability to promote relaxation of vascular smooth muscle.

    Acute rhinosinusitis is a common illness in children. Viral upper respiratory tract infection is the most common presentation of rhinosinusitis. Most children resolve the infection spontaneously and only a small proportion develops a secondary bacterial infection. The proper choice of antibiotic therapy depends on the likely infecting pathogens, bacterial antibiotic resistance, and pharmacologic profiles of antibiotics. Amoxicillin-clavulanate is currently recommended as the empiric treatment in those requiring antimicrobial therapy. Isolation of the causative agents should be considered in those who failed the initial treatment. In addition to antibiotics, adjuvant therapies and surgery may be used in the management of acute bacterial rhinosinusitis.

    Classic treatment for pyriform sinus fistula (PSF) has been surgical excision; however, less invasive therapeutic alternatives whose aim is the obliteration of the sinus have been described subsequently. The authors present a technical modification of endoscopic sclerosis with diathermy (ESD): continuous infusion of air flow through the flexible endoscope was used to distend the pyriform sinus and facilitate recognition of the fistula opening. The sinus obliteration was performed with a wire guide and diathermy. In the last 15 years, 9 patients were diagnosed of suffering from PSF in our institution. Initial treatment was antibiotics therapy associated in some cases to cervical abscess drainage. Fistulectomy was performed in 4 cases and ESD in 4. The ninth patient received both treatments, performing electrocauterization after a surgical recurrence. Three of the patients who underwent surgery relapsed; none treated by ESD did, or had any complications. In our experience, endoscopic sclerosis with pneumatic distension is a simple technique, reproducible, not invasive and very effective; hence we consider it might become a first line therapy for PSF.

    Allergic fungal sinusitis (AFS) is a subtype of eosinophilic chronic rhinosinusitis (CRS) characterized by type I hypersensitivity, nasal polyposis, characteristic computed tomography scan findings, eosinophilic mucus, and the presence of fungus on surgical specimens without evidence of tissue invasion. This refractory subtype of CRS is of the great interest in the pediatric population, given the relatively early age of onset and the difficulty in managing AFS through commercially available medical regimens. Almost universally, a diagnosis of AFS requires operative intervention. Postoperative adjuvant medical therapy is a mainstay in the treatment paradigm of pediatric AFS.

Along with metastatic lymph nodes in the neck it showed high 18F-FDG uptake in a polypoidal structure in the sinus sphenoidalis. When asked she had no related symptoms due to the sphenoid polyp and the CT-scan showed no bone destruction. To rule out malignancy a biopsy was made showing benign sinonasal papilloma of oncocytic origin. High 18F-FDG PET uptake can be seen in benign structures and should therefore not be the only predictor for malignancy.

    Background: Pituitary adenomas (PAs) are abnormal benign tumors that develop in the pituitary gland. This study aimed to assess the prevalence of different types of PAs with an indication for trans-sphenoidal surgery in a well-defined population referred to Loghman Hakim Hospital during 2001–2013. Subjects and Methods: In this retrospective study, the prevalence rate and symptoms associated with pituitary mass and hormone excess in operated patients were investigated. The diagnosis was verified after retrieval of clinical, hormonal, radiological, and pathological data. Demographic data were collected in all cases. Descriptive analysis, t-test, one-way analysis of variance and Fischer exacts test were used. Results: A total of 278 patients with PAs who underwent surgical interventions were evaluated. Most of the patients were aged 40–50 years with an average of 41 ± 14. The most prominent complaint was pressure effect, which was detected in 153 cases (55.2%). At the second place, hormonal disorders were observed in 125 cases (44.8%). Type of pituitary tumors were: Prolactinomas (29.1%), growth hormone (GH)-producing tumors (25%), nonfunctioning PAs (28.4%), adrenocorticotropic hormone (ACTH)-producing tumors (2.1%), thyroid stimulating hormone (TSH)-producing tumors (0.7%), GH/prolactin (13.6%), GH/ACTH (0.3%), and TSH/ACTH (0.3%). Fifty-seven patients presented with recurrent adenomas. Pituitary apoplexy was found in 11 patients. One case of Sheehan syndrome was recorded among these. The correlations between clinical symptoms and patients, age and sex were not significant. Conclusion: The overview of demographic characteristics in Iranian patients with PAs with surgical indication has been discussed in the present investigation. The prevalence of different types of PAs and the most common clinical symptoms have been demonstrated. PMID:26693430

    The coronary sinus collects blood from the heart walls. It is a structure which presently plays a very important clinical role in invasive cardology. In this study, the occurrence of the main tributaries of the coronary sinus was examined as wall as the topography of their outlet portions. Material consistied of 150 adult human hearts of both sexes from aged 18 to 85 years. In the examined material, the graet and middle cardiac veins as well as the posterior vein of the left ventricle were always obserwed. The remaining tributaries of the coronary sinus were less stable. The outlet portions of the main veins of the heart were characterized by significant variability.

    The surface electrocardiogram (ECG) holds many clues with regard to the etiology of bradycardia and site of atrioventricular (AV) block. Bedside maneuvers may prove helpful in cases of 2:1 AV block or situations where the data is not all concordant. Wenckebach conduction may occur in any region of the heart, and there are nonpathologic mimickers of Mobitz II AV block as well. The surface ECG may aid in the inference of etiology for better than expected or slowed rather than blocked AV conduction. Sinus node dysfunction may present in several forms and often accompanies other conduction system disease. On occasion invasive studies may be required to help elucidate the mechanism of bradycardia.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres.

    2016-01-01

    Charles Bonnet syndrome (CBS) can develop after trans-sphenoidal adenomectomy (TSA); however, the neural mechanisms remain unknown. Sensory deprivation and releasing phenomenon are both hypothetical explanations for this condition; however, there is no definite evidence that strongly supports either supposition. We report the first case of CBS after TSA without optic nerve atrophy. Postoperatively, the patient's vision seemed to be relatively well preserved, apart from the left-side hemianopsia in the right eye. Distinctive visual hallucinations only appeared when his eyes were closed, and these responded to quetiapine in a dose-dependent manner. Dose dependent change in colors and formation of hallucination was reported. Two weeks after quetiapine initiation, the patient's CBS was completely resolved. This unique case suggests that blocking sensory input from the periphery is more critical than neural damage of the bottom-up connection to the visual association cortex. In addition, quetiapine should be considered as a specific treatment for CBS. PMID:27757139

    Primary Ewing's sarcoma is an uncommon lethal tumour of the long bones and pelvic girdle mainly affecting children and young adults. An origin in the cranial bones is extremely rare. We report a unique case of primary involvement of the greater wing of sphenoid bone in a 16-year-old patient. Aggressive management using microsurgical resection, radiotherapy and chemotherapy was curative. Localized, primary Ewing's sarcoma of the cranial bones should be considered as a distinct clinicopathological entity with an extremely low rate of dural penetration and metastases, and with a relatively better prognosis as compared with those of long bones and pelvic girdle. In neurosurgical practice, primary Ewing's sarcoma of the cranial bones requires early aggressive management to achieve adequate long-term prognosis and cure.

    A unilateral tumour in the nasal cavity or paranasal sinuses is commonly caused by polyps, cysts, and mucoceles, as well as invasive tumours such as papillomas and squamous cell carcinomas. Schwannomas, in contrast, are rare lesions in this area (Minhas et al., 2013). We present a case of a 52-year-old female who presented with a 4-year progressive history of mucous hypersecretion, nasal obstruction, pain, and fullness. Imaging of the paranasal sinuses showed complete opacification of the entire left nasal cavity and sinuses by a tumour causing subsequent obstruction of the frontal and maxillary sinuses. The tumour was completely excised endoscopically. Histopathology was consistent with that of a schwannoma. PMID:27379190

    The authors report a rare case of renal cell carcinoma (RCC) metastasis to the paranasal sinuses. The authors review RCC and its potential for sinonasal metastasis and discuss the variable presentation and need for clinical suspicion for early diagnosis and treatment. A 74-year-old man presented with numbness of the left side of the face, reduced visual acuity and ptosis 12 years after nephrectomy for RCC. Imaging studies showed a lesion in the left pterygopalatine fossa and the histological features supported the diagnosis of metastatic RCC. RCC metastasis to the paranasal sinuses is very rare and can present with various symptoms depending on the affected organ. These symptoms occasionally are the initial manifestation of renal RCC and it is very important to recognise them so that the patient receives the appropriate therapy to improve survival.

    Summary Congenital preauricular sinus is a malformation of the preauricular soft tissues with an incidence ranging between 0.1 and 0.9% in Europe and the United States. It presents a high risk of recurrence when treated by a standard surgical technique (simple sinectomy), the incidence of which is reported to be between 19% and 40%. The supra-auricular approach, proposed by Prasad et al. in 1990, is easier to perform and presents a lower recurrence risk. Personal experience is presented in the treatment of congenital preauricular sinus with the supra-auricular approach as first choice or in the case of recurrence following previous standard surgery. This report includes a short review of the literature in order not only to focus on the supra-auricular approach and check the efficacy as far as concerns reduction of recurrence risk but also to contribute to a more widespread use of this method.

    2016-01-01

    Objectives The maxillary sinus mucosa is reported to recover to preoperative sterility after sinus floor elevation. However, when drainage of maxillary sinus is impaired, recovery can be delayed and maxillary sinusitis can occur. Therefore, in this study, we investigated the correlations between anatomic variants that can interrupt the ostium of the maxillary sinus and incidence of complication after sinus lifting. Materials and Methods The subjects are 81 patients who underwent sinus lifting in Wonkwang University Dental Hospital (Iksan, Korea). Computed tomography (CT) images of the subjects were reviewed for presence of nasal septum deviation, anatomic variants of the middle turbinate, and Haller cells. Correlations between anatomic variations and occurrence of maxillary sinusitis were statistically analyzed. Results Patients with anatomic variants of ostio-meatal units, such as deviated nasal septum, concha bullosa or paradoxical curvature of the middle turbinate, or Haller cells, showed a higher rate of complication. However, only presence of Haller cell showed statistically significant. Conclusion Before sinus lifting, CT images are recommended to detect anatomic variants of the ostio-meatal complex. If disadvantageous anatomic variants are detected, the use of nasal decongestants should be considered to reduce the risk of postoperative sinusitis. PMID:27847736

    The present study was undertaken to test a simple system for the identification of unknown bodies using spiral CT images of frontal sinus and other skull measurements among selected Iraqi sample. Ninety patients (45 males and 45 females) with age range from 20 to 49 years were selected in this study. Three features and two groups of measurements of frontal sinus and three skull dimensions were obtained from the CT images. Three basic features were F (presence or absence of frontal sinus), S (septum) and S (scalloping). Measurements selected for the study were frontal sinus width, height and anteroposterior length. In addition to measurements of total width, the distance between the highest points of the two sinuses, the distance between the highest points of each sinus to its maximum lateral limit. Skull measurements included; maximum skull length, prostio-bregmatic height and maximum skull width. All data were subjected to a descriptive and discriminative analysis using the SPSS (Version 17.0). The pre-post comparison (number of discordant items) resulted in 95% accurately predicted perfect match for intra-examiner calibration and 90% accurately predicted perfect match for inter-examiners calibration and the result for one discordant item was 5% for intra-examiner calibration and 10% for inter-examiners calibration. The discriminative analysis showed that the ability of the frontal sinus to identify gender was 76.9%, adding the skull measurements to the frontal sinus measurements gave a higher overall classification accuracy for gender (85.9%). Frontal sinus measurements are valuable method in differentiating gender. Adding skull measurements to the frontal sinus measurements can significantly improve accuracy of gender determination using discriminant analysis. CT based films can provide valuable and precise measurements not only for frontal sinus but even for the whole skull that cannot be approached by other means.

    Pott's puffy tumor is a rare complication of frontal sinusitis characterized by swelling and edema in the brow due to a subperiosteal abscess associated with frontal osteomyelitis. Added complications are cellulitis by extension to the orbit and intracranial infection by posterior extension, with high risk of meningitis, intracranial abscess, and venous sinus thrombosis. Early diagnosis and aggressive medical or surgical treatment are essential for optimal recovery of affected patients. In the antibiotic age it is extremely rare, with very few cases described in the recent literature. A case is presented of a Pott inflammatory tumor in a 7 year-old boy, as a complication of acute pansinusitis who presented with front preseptal swelling and intracranial involvement with thrombosis of ophthalmic and superior orbital veins and frontal epidural abscess extending to the subarachnoid space.

    We present an unusual dentoalveolar fracture case who had displacement of teeth into maxillary sinus cavity. This patient was 15 years old. He had oral bleeding and lost teeth after falling from the top of a building. Examination of maxillofacial region showed that there were left maxillary teeth lost, alveolar fracture, gingival bleeding and laserations. Maxillofacial bones were found intact. Canine, both premolars and the first molar teeth on left maxilla were lost. Pantomographic evaluation viewed two teeth in the left maxillary sinus. In addition, computerized tomography clearly showed oroantral fistula, alveolar fracture and teeth into maxillary sinus. Extraction of teeth from sinus cavity was performed as well as repair of oroantral fistula and alveolar fracture. This patient is thought that dentoalveolar injury may be more serious than expected according to the oral examination and it requires careful evaluation, even if dentoalveolar trauma does not pose a significant morbid risk.

    Intra-abdominal abscess and an intractable abdominal wall sinus forty years after splenectomy is rare, which has not been described previously in the surgical literature. We report the management of a patient who had presented with an intractable sinus on his left hypochondrium forty years after having undergone splenectomy and cholecystectomy, which persisted for more than two years despite repeated surgery and courses of antibiotics and compromised quality of life significantly from pain. A sinogram and computerised tomographic scan followed by exploration and laying open of the sinus delivered multiple silk sutures used for ligation of splenic pedicle, led to complete resolution of the sinus. It is important to avoid using non-absorbable silk sutures during splenectomy when splenectomy is undertaken in a contaminated field. Appropriate imaging and exploration is mandatory for its resolution. PMID:28138442

    A sinusitis caused by Cochliobolus hawaiiensis (anamorph: Bipolaris hawaiiensis) was diagnosed in metropolitan France in a patient originating from New Caledonia. The patient completely recovered after surgical treatment consisting in marsupialization of the mucoceles and removal of the fungus balls located in the left nasal cavity and the left maxilla and ethmoid sinuses. One year after, both endoscopic examination and CT scan of the sinuses were normal. Various clinical presentations of diseases associated with C. hawaiiensis have been reported. A review of the literature indicates that although C. hawaiiensis is very rarely reported in Europe, it is one of the major rhinosinusitis agents in areas with a relatively warmer climate, such as India or Southwestern USA. This is the first report of a sinusitis caused by C. hawaiiensis diagnosed in France, with a total recovery outcome.

    Benign paroxysmal positional vertigo (BPPV) is a relatively rare condition characterized by onset of rotation dizziness triggered by head movements or change in posture. BPPV etiology includes head injury, infection, vascular disorders, surgical trauma, and idiopathic events. This report presents a case of protracted BPPV following osteotome sinus floor elevation and simultaneous implant placement. A 49-year-old female suffered intense vertigo and nausea immediately after implant placement using an osteotome sinus floor elevation procedure, especially when changing head position while sitting upright. Despite antivertigo medications, the condition did not improve. Following referral to a neurotologist, BPPV contralateral to the operation site was diagnosed 14 days after the osteotome sinus floor elevation procedure. The Epley's maneuver was then applied and, gradually, symptoms of BPPV disappeared 3 months after the implant surgery. No recurrence of BPPV was observed during further 3-month follow-up. Prevention and management of osteotome sinus floor elevation-related BPPV are reviewed in this report.

    A maxillary sinus mucocele is an infrequent but benign lesion that develops from the obstruction of a seromucous glandular duct of the maxillary sinus mucosa. This clinical entity is generally asymptomatic and self-limited. Mucoceles are described as rounded dome-shaped soft tissue masses frequently located on the floor of the maxillary sinus. In this paper, we present a case of a slightly radiopaque well defined shadow arising from the left maxillary sinus floor that produced the root resorption of the upper second left molar. After the surgical removal of the lesion through a Caldwell-Luc approach, histologic study confirmed the initial diagnosis of mucocele. This case report emphasizes the need of clinical and radiologic follow-up to detect any complications associated with these benign lesions, because, in rare occasions, they can show an aggressive growth pattern.

    Orbital manifestations occur in less than 1% of patients with neurofibromatosis type 1 (NF1). These manifestations are frequently associated with sphenoid wing dysplasia. The typical radiologic feature is partial or total loss of the greater wing of the sphenoid bone, which leads to herniation of the temporal lobe through the orbital cavity resulting in proptosis and pulsating exophthalmos. Traditional reconstruction of this bone defect involves split bone grafting or titanium mesh. However, these techniques have some limitations due to bone resorption and infection risk. We report the use of 0.85 mm titanium-reinforced porous polyethylene implant sheet in three cases of orbital neurofibromatosis with sphenoid dysplasia. The role of this material was to create a barrier between the brain and orbital cavity. The implant sheet was modeled intraoperatively to reconstruct the orbital cavity anatomy and fitted without any screws. The malleability of the implant allows quick reconstruction of the curved orbital skeleton. Furthermore, the implant doesn't interfere with postoperative imaging and may decrease risk infection.

    Background Cerebral venous strokes due to cerebral venous sinus thrombosis (CVST) have varied presentation and clinical outcome. Despite aggressive medical treatment with optimal anticoagulation, some patients develop progressive neurologic deterioration causing significant morbidity and mortality. The aim of the present series is to analyze the safety and efficacy of in situ thrombolysis in patients with cerebral venous sinus thrombosis in severe clinical grade and refractory to conventional medical management. Materials and methods Twenty-nine patients with cerebral venous thrombosis who received in situ thrombolysis during a 3-year period (April 2013 to April 2016) were included in the study. Tissue plasminogen activator (tpa) was used in all the patients. The lytic agent was infused into the sinus via the micro catheter. Data regarding demographic, clinical, and radiologic features were analyzed in all the patients. Results Recanalization of the affected sinuses was achieved in all the cases. Twenty-four patients had good outcome (mRs 0 or1) and three patients had mild deficits (mRs 2). One patient had moderate disability (mRs 3). One patient succumbed due to increased hematoma causing midline shift and transtentorial herniation. At 3 months follow–up, 26 patients were asymptomatic and two patients had minor symptoms. Conclusion Local intrasinus thrombolysis (LIST) is safe and effective method in patients with poor clinical grade and the present study highlights the benefit of thrombolysis, particularly in patients unresponsive to anticoagulation. The improved efficacy of this therapy depends on early recognition of worsening symptoms and timely intervention. PMID:27829970

    Carotid sinus reflex hypersensitivity is a known cause of syncope in humans. The condition is characterized by cardioinhibition and vasodepression, each to varying degrees. The extent and importance of sympathoinhibition has not been determined in patients with carotid sinus hypersensitivity. This study reports on the extent of sympathoinhibition measured directly directly during carotid massage with and without atrioventricular sequential pacing, in a patient with symptomatic carotid sinus reflex hypersensitivity. Carotid massage elicited asystole, hypotension and complete inhibition of muscle sympathetic nerve activity. Carotid massage during atrioventricular pacing produced similar sympathoinhibition, but with minimal hypotension. Therefore, sympathoinhibition did not contribute importantly to the hypotension during carotid massage in the supine position in this patient. Further investigations are required to elucidate the relation of sympathoinhibition to hypotension in patients with carotid sinus hypersensitivity in the upright position.

    The palatal sinus lift is a good choice for patients with scarred buccal soft tissue and those with poor wound healing such as smokers or diabetics or when visual side effects such as swelling must be concealed. We provide a surgical protocol for palatal sinus lifting without a vertical release incision. The incision is started in a slightly palatal aspect, at the distal end of the dental arch, and describes a curve laterally on the alveolar crest while running in a mesial direction. As a marginal incision, it can continue to the central incisor. Submucosal exposure will lift the gum and the greater palatine artery. After insertion of a tongue depressor, the sinus is opened on the palatal side, opposite the zygomaticoalveolar crest, using a rose bur or a piezotome. After sinus augmentation, the incision is easy to close, and the wound will heal smoothly.

    BACKGROUND—The paranasal sinuses are intimately related to the orbit and consequently sinus disease or surgery may cause severe orbital complications. Complications are rare but can result in serious morbidity, the most devastating of which is severe visual loss.
METHODS—A retrospective review was undertaken of four cases of severe orbital trauma during endoscopic sinus surgery.
RESULTS—All the cases suffered medial rectus damage, one had additional injury to the inferior rectus and oblique, and two patients were blinded as a result of direct damage to the optic nerve or its blood supply.
CONCLUSION—Some ophthalmic complications of endoscopic sinus surgery are highlighted, the mechanisms responsible are discussed, and recommendations for prevention, early recognition, and management are proposed.

    A 14-month-old girl had purulent discharge from a sinus over the subpubic region for 2 weeks. Radiography and voiding cystourethrography revealed a 4.5 cm. long fistula extending to the retropubic region without any connection to the lower urinary tract. The fistula was excised. Histological findings revealed that the fistula had 3 different types of epithelium: stratified squamous, transitional and columnar. Clinical and pathological findings indicated that the sinus was most likely a remnant of the cloaca.

    Background: Identification of an individual whether living or deceased is of paramount importance in maintaining the integrity of the society. A simple, reliable, and efficacious method always finds a way for easier acceptance and inclusion in any discipline. Likewise, identification of an individual using the radiographic frontal sinus patterns is a simple technique which emphasized to conduct the study with a proven result. Objective: The objective of the study is to evaluate the radiographic configurations of frontal sinuses for their uniqueness based on different parameters. Study Group and Methods: Study group consisted of thirty individuals (15 males and 15 females) of age between 20 and 30. Individuals with the history of sinusitis, surgery, or any trauma were not included in the study. Paranasal sinus views were taken using standard exposure parameters, and the radiographs were assessed for their uniqueness. Results: The radiographs were assessed for area size, area asymmetry, superiority of the upper border, outline of the upper border, presence or absence of partial septa and supraorbital cells, and based on these results, a unique code number was assigned to each individual to prove the uniqueness. Conclusion: A frontal sinus comparison is particularly useful when no other means of an individual identification are available. Caution must be taken regarding the physiological and pathological changes (trauma, infection, old age, surgery, etc.) and postmortem changes and about the technical issues while taking a radiograph (distance, angle, orientation of the skull). In spite of all these issues, the configuration of frontal sinus is an excellent individualizing feature. PMID:27829755

    Objective To determine prognostic factors that independently predict response to antimicrobial therapy in children with acute sinusitis. Study design 206 children meeting a priori clinical criteria for acute sinusitis who were given antimicrobial therapy by their primary care provider were included. The severity of symptoms in the 8 to 12 days after treatment was initiated was followed using a validated scale. We examined the univariate and multivariate association between factors present at the time of diagnosis (symptoms, signs, nasopharyngeal culture result, radiograph results) and time to resolution of symptoms. This study was conducted 8 to 10 years after 7-valent pneumococcal conjugate vaccination was introduced, but before introduction of the 13-valent pneumococcal conjugate vaccination. Results Children with proven nasopharyngeal colonization with Streptococcus pneumoniae improved more rapidly (6.5 vs. 8.5 median days to symptom resolution) than those who were not colonized with S. pneumoniae. Age and radiograph findings did not predict time to symptom resolution. Conclusions In children with acute sinusitis, proven nasopharyngeal colonization with S. pneumoniae at presentation independently predicted time to symptom resolution. Future randomized, placebo-controlled trials could investigate the usefulness of testing for the presence of nasopharyngeal pathogens as a predictor of response to treatment. PMID:24367985

    Herpes zoster results from reactivation of the varicella zoster virus (VZV). Zoster sine herpete (ZSH) is an uncommon manifestation of VZV infection and presents with similar symptoms but without the vesicular rash. We describe an unusual case of lateral sinus thrombosis (LST) that developed during the clinical course of ZSH in the C2 distribution. A 55-year-old woman presented with a 3-day history of left temporal and postauricular pain, nausea, vomiting, and mild photophobia. She denied otalgia, otorrhea, and hearing loss. Examination revealed hyperesthesia in the left C2 nerve root distribution without evidence of herpetic rash. A computed tomography scan showed minimal fluid in the left mastoid cavity (not mastoiditis) and thrombus within the left lateral and sigmoid dural sinus. Magnetic resonance imaging and magnetic resonance angiogram confirmed these findings. Laboratory studies revealed elevated neurotrophic immunoglobulin G levels to VZV. Hypercoagulable studies were normal. She was subsequently treated with Neurontin, acyclovir, and anticoagulation. Her symptoms improved, and she was discharged 3 days later. LST is generally a complication of middle ear infection. Nonseptic LST, however, may result from dehydration, oral contraceptive use, coagulopathy, or thyroid disease. This unusual case raises the suspicion that thrombosis resulted from VZV associated thrombophlebitis in the ipsilateral cerebral venous sinuses along the second cervical nerve root distribution. A high index of suspicion is necessary in such cases so that a different treatment course can be identified and antiviral medication initiated promptly.

However, the concentration of these microorganisms within the sinuses is still unknown. We show that flow cytometry can be used to enumerate bacteria and virus-like particles (VLPs) in sinus flush samples of CRS patients. This was achieved through trialling 5 sample preparation techniques for flow cytometry. We found high concentrations of bacteria and VLPs in these samples. Untreated samples produced the highest average bacterial and VLP counts with 3.3 ± 0.74 x 107 bacteria ml-1 and 2.4 ± 1.23 x 109 VLP ml-1 of sinus flush (n = 9). These counts were significantly higher than most of the treated samples (p < 0.05). Results showed 103 and 104 times inter-patient variation for bacteria and VLP concentrations. This wide variation suggests that diagnosis and treatment need to be personalised and that utilising flow cytometry is useful and efficient for this. This study is the first to enumerate bacterial and VLP populations in the maxillary sinus of CRS patients. The relevance of enumeration is that with increasing antimicrobial resistance, antibiotics are becoming less effective at treating bacterial infections of the sinuses, so alternative therapies are needed. Phage therapy has been proposed as one such alternative, but for dosing, the abundance of bacteria is required. Knowledge of whether phages are normally present in the sinuses will assist in gauging the safety of applying phage therapy to sinuses. Our finding, that large numbers of VLP are frequently present in sinuses, indicates that phage therapy may represent a minimally disruptive intervention towards the nasal microbiome. We propose that flow cytometry can be used as a tool to assess microbial biomass dynamics in sinuses and other anatomical locations where infection can cause disease. PMID:27171169

    Nasofrontal dermoid with sinus tract extending to the nasal tip is rare in adults. It is unique in its embryological origin, presentation, and management. Pathogenesis involves the incomplete obliteration of the developing neuroectoderm. A sinus opening with intermittent oily discharge is characteristic. Associated intracranial extension may lead to meningitis and brain abscess. We present a case of a 21-year-old adult having a nasofrontal sinus tract with intracranial extension who presented with recurrent episodes of meningitis and discuss the physical findings with relevance to embryology, elaborating on the importance and means of addressing the intracranial as well as extracranial components for complete treatment.

    Sinus blockages are a common reason for physician visits, affecting 1 out of 7 in the United States. Over 20 million cases of acute bacterial sinusitis become chronic and require medical treatment. Diagnosis in the primary care setting is challenging because symptom criteria (via detailed clinical history) plus objective imaging (CT or endoscopy) is recommended. Unfortunately, neither option is routinely available in primary care. Our previous work demonstrated that low-cost near infrared (NIR) transillumination instruments produced signals that correlated with the bulk findings of sinus opacity measured by CT. We have upgraded the technology, but questions remain such as finding the optimal arrangement of light sources, measuring the influence of specific anatomical structures, and determining detection limits. In order to begin addressing these questions, we have modeled NIR light propagation inside the adult human head using a mesh-based Monte Carlo algorithm (MMCLab) applied to a detailed anatomical head model constructed from CT images. In this application the sinus itself, which under healthy conditions is a void region (e.g., non-scattering), is the region of interest instead of an obstacle to other contrast mechanisms. We report preliminary simulations that characterize the changes in detected intensity due to clear (i.e., healthy) versus blocked sinuses. We also ran simulations for two of our clinical cases and compared results with the measurements. The simulations presented herein serve as a proof of concept that this approach could be used to understand contrast mechanisms and limitations of NIR imaging of the sinus cavities.

    Pasteurella multocida group B, serotype 3, was isolated from sinusitis-affected khaki Campbell ducks. To study the role of P. multocida in sinusitis, commercial khaki Campbell ducks were experimentally infected with P. multocida alone or combined with Escherichia coli. In Expt. 1, experimental ducks were infected with P. multocida intranasally or ocularly. A comparison was done by intranasal inoculation with pooled nasal discharge from the affected ducks or phosphate-buffered saline. The ducks intranasally inoculated with the nasal discharge or P. multocida showed sinusitis. In Expt. 2, E. coli alone or a combination of P. multocida and E. coli was intranasally inoculated into experimental ducks. The ducks intranasally inoculated with the combination of P. multocida and E. coli had sinusitis, the same as found in the field but less severe than that of the field cases. Pasteurella multocida was already present in litter/floor of duck farms. We concluded that P. multocida played a role in induction of sinusitis. However, the sinusitis in ducks may be initiated by poor management, especially in the brooding period of ducks.

    Variations in cerebral venous development can influence the ability to regulate drainage. In cerebral sinovenous thrombosis, these variations can be associated with elevated intracranial pressure. We present a series of pediatric patients with unilateral cerebral sinovenous thrombosis and investigate whether the contralateral venous sinus size increases the risk of developing elevated intracranial pressure. Patients diagnosed with a unilateral cerebral sinovenous thrombosis were identified by querying our institutional radiology data base. The difference in the occurrence of elevated intracranial pressure in patients with cerebral sinovenous thrombosis with and without hypoplastic venous sinuses was studied. Twelve cases of unilateral cerebral sinovenous thrombosis met the inclusion criteria and had sufficient images. Six patients had hypoplastic contralateral venous sinuses. The presence of hypoplastic contralateral venous sinus in the setting of thrombosis of a dominant sinus was associated with elevation of intracranial pressure (83% versus 0%, P = .015). Patients with cerebral sinovenous thrombosis and contralateral hypoplastic venous sinuses are at higher risk of developing elevated ICP and may benefit from screening with an ophthalmologic examination.

    therapeutic concept is followed in CRS based on conservative and surgical methods. Nasal sinus surgery is considered nowadays as effective and safe in children. Based on the assumption that adenoids are a reservoir for bacteria, from which recurrent infections of the nose and nasal sinus originate, the adenoidectomy is still defined as a cleansing procedure in rhinosinusitis. 69.3% of the children had benefit from adenoidectomy. Comorbidities, such as pediatric bronchial asthma, presently play an even more important role in the therapy of rhinosinusitis; therefore, it is often wise to have the support of pediatricians. In western European countries 40% of children presently suffer from allergic rhinitis, in which pronounced nasal obstruction can cause disturbed growth in facial bones. An early therapy with SIT may prevent the development of bronchial asthma and secondary sensitization to other allergens. Therefore, SIT is recommended in treatment of allergic rhinitis whenever, if possible. The assessment of diagnostic tools is for the examiner not often possible due to the lack of evidence. Rhinosurgical approaches are often described in study reports; however, they lack the standard prospective randomized long-term study design required nowadays and can only be evaluated with caution in the literature.

    The frequent association of asthma and paranasal sinusitis has been ascribed to a nasobronchial reflex, aspiration of sinus secretions, or enhanced beta-adrenergic blockade. We investigated possible pulmonary aspiration in a pilot study (eight patients) and follow-up study (13 patients) by means of a radionuclide technique. In the pilot study, the aim was to demonstrate aspiration as well as visibility of the radionuclide in the thorax during a period of 24 hours. The radionuclide was initially placed bronchoscopically in the bronchial tree in four patients and was still clearly visible in the same position after 24 hours in three patients. Aspiration from the nasopharynx was unequivocally demonstrated in two of four patients with depressed consciousness. The follow-up study population consisted of four patients with maxillary sinusitis only and nine patients with sinusitis and asthma. The radionuclide was placed in a maxillary sinus during therapeutic puncture. In the patients with only sinusitis as well as patients with asthma and sinusitis the radionuclide could be demonstrated in the maxillary sinus, nasopharynx, esophagus, and lower gastrointestinal tract during a 24-hour period. However, no pulmonary aspiration of radionuclide could be demonstrated in any patient. We conclude that seeding of the lower airways by mucopurulent secretions is unlikely to account for coexistent pulmonary disease. The association is probably related to generalized mucosal disease affecting both upper and lower airways.

    Objectives: Maxillary sinus augmentation surgical techniques have evolved greatly allowing successful placement of dental implants in the atrophic posterior maxillary region. The purpose of the present study is to evaluate the clinical and radiological outcomes and postoperative morbidity of sinus floor elevation procedures performed using the minimally invasive surgical technique the Sinu lift system. Materials and Methods: Sinus lift procedure was done using the sinu lift system by a transcrestal approach and bone augmentation was done on ten systemically healthy patients using β- tricalcium phosphate and platelet rich plasma mix. The study was evaluated upto six months period with bone related parameters being assessed at base line using CT scan, OPG and after six months the results were analysed using SPSS Version 18.0 software (p < 0.01 (0.005). Wilcoxson signed rank sum test was used to correlate between preoperative and postoperative measurements. Implant placements were done at the desired area of sinus augmentation with a two year follow up. (Nobel Biocare, Nobel Biocare Holding AG, Zürich-Flughafen, Switzerland) Results: The augmented sites had a significant increase in the bone parameters at the desired grafted region. The mean gain in bone height as observed in CT Scan had revealed increased measurements from 5.80mm±0.98 to 10.20mm±1.68 at the sixth month evaluation. This was statistically significant (0.005). Clinically, no complications were observed during or after the surgical procedure. Conclusion: Within the limitations of this study, the Sinu lift system with a controlled working action resulted in high procedural success and this procedure may be an alternative to the currently used surgical methods.

    The aim of this study was to evaluate the precision and accuracy of linear measurements of maxillary sinus made in tomographic films, by comparing with 3D reconstructed images. Linear measurements of both maxillary sinus in computed tomography CT of 17 patients, with or without lesion by two calibrated examiners independently, on two occasions, with a single manual caliper. A third examiner has done the same measurements electronically in 3D-CT reconstruction. The statistical analysis was performed using ANOVA (analyses of variance). Intra-observer percentage error was little in both cases, with and without lesion; it ranged from 1.14% to 1.82%. The inter-observer error was a little higher reaching a 2.08% value. The accuracy presented a higher value. The perceptual accuracy error was higher in samples, which had lesion compared to that which had not. CT had provided adequate precision and accuracy for maxillary sinus analyses. The precision in cases with lesion was considered inferior when compared to that without lesion, but it can't affect the method efficacy.

    INTRODUCTION Exostoses in paranasal sinuses have been reported in the otolaryngology literature, but they have not been described in the dental literature to our knowledge. The aim of this article is to describe an idiopathic and rare case of bilateral exostosis obtained by cone-beam computed tomography. PRESENTATION OF CASE The case shows a healthy and asymptomatic patient with a different size and form of exostoses in both maxillary sinuses. DISCUSSION It is difficult to clinically diagnose the antral exostosis due the asymptomatic nature of this condition, unless the approach would be through endoscope. Sometimes this condition is related with nasal irrigants, however in this case the patient asserted not having used nasal irrigation ever; thus, it is impossible to relate this kind of treatment as a principal cause. CONCLUSION The published data of exostoses in maxillary sinus seem to be limited in the dental literature, and this condition is important to consider in an implant treatment planning. Also, it is important to perform a follow-up of the cases in trying to find the possible causes of exostosis. PMID:25128728

    Carotid-cavernous fistulas (CCFs) are anomalous communications between the carotid arterial system and the venous cavernous sinus. They can arise because of spontaneous or trauma causes. Most caroticocavernous fistulas are of spontaneous origin and unknown etiology. Spontaneous CCF may also be associated with cavernous sinus pathology such as arteriosclerotic changes of the arterial wall, fibromuscular dysplasia, or Ehler-Danlos syndrome. Traumatic CCFs may occur after either blunt or penetrating head trauma. Their clinical presentation is related to their size and to the type of venous drainage, which can lead to a variety of symptoms, such as visual loss, proptosis, bruit, chemosis, cranial nerve impairment, intracranial hemorrhage (rare), and so on. Treatment by endovascular transarterial embolization with electrolytically detachable coils is a very effective method for CCF with good outcomes. Carotid-cavernous fistulas have been rarely reported after craniofacial surgery and are uncommon pathologies in otolaryngology practice. In this study, we report a 40-year-old woman with CCF secondary to blunt trauma of functional endoscopic sinus surgery.

    Cerebral Sinovenous Thrombosis (CSVT) is a serious complication of L-asparaginase chemotherapy for leukemia in children. Clinical features of headache, altered consciousness, focal neurological deficit, and seizures developing during or immediately after treatment with L-asparaginase should alert the treating physician to the possibility of CSVT. Immediate imaging of the brain should be done using CT and MRI and the veins should be visualized noninvasively by CT and MR venography. We report two children on induction therapy for acute leukemia who presented with seizures, headache, and altered consciousness. Venous infarcts with and without hemorrhage were seen on CT in one patient and the empty delta sign was seen after contrast injection; however, the early changes were missed by CT. MRI detected dural sinus thrombosis relatively earlier in another patient, while the CT findings were equivocal; in this patient, contrast-enhanced MRI showed the empty delta sign and MR venography confirmed absent flow in the superior sagittal sinus, which was diagnostic of sinus thrombosis. Rapid anticoagulation was started with heparin and maintained with warfarin. The child with a unilateral small nonhemorrhagic infarct made a complete recovery while the other, with bilateral hemorrhagic infarcts, did not survive. We stress the importance of early diagnosis of CSVT using CT and MRI in children with leukemia being treated with L-asparaginase; this will permit timely treatment. PMID:21042505

    One hundred fifty-three patients with medically refractory partial epilepsy underwent chronic stereotactic depth-electrode EEG (SEEG) evaluations after being studied by positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) and scalp-sphenoidal EEG telemetry. We carried out retrospective standardized reviews of local cerebral metabolism and scalp-sphenoidal ictal onsets to determine when SEEG recordings revealed additional useful information. FDG-PET localization was misleading in only 3 patients with temporal lobe SEEG ictal onsets for whom extratemporal or contralateral hypometabolism could be attributed to obvious nonepileptic structural defects. Two patients with predominantly temporal hypometabolism may have had frontal epileptogenic regions, but ultimate localization remains uncertain. Scalp-sphenoidal ictal onsets were misleading in 5 patients. For 37 patients with congruent focal scalp-sphenoidal ictal onsets and temporal hypometabolic zones, SEEG recordings never demonstrated extratemporal or contralateral epileptogenic regions; however, 3 of these patients had nondiagnostic SEEG evaluations. The results of subsequent subdural grid recordings indicated that at least 1 of these patients may have been denied beneficial surgery as a result of an equivocal SEEG evaluation. Weighing risks and benefits, it is concluded that anterior temporal lobectomy is justified without chronic intracranial recording when specific criteria for focal scalp-sphenoidal ictal EEG onsets are met, localized hypometabolism predominantly involves the same temporal lobe, and no other conflicting information has been obtained from additional tests of focal functional deficit, structural imaging, or seizure semiology.

  3. Sisters of the sinuses: cetacean air sacs.

    Reidenberg, Joy S; Laitman, Jeffrey T

    2008-11-01

    This overview assesses some distinguishing features of the cetacean (whale, dolphin, porpoise) air sac system that may relate to the anatomy and function of the paranasal sinuses in terrestrial mammals. The cetacean respiratory tract has been modified through evolution to accommodate living in water. Lack of paranasal sinuses in modern cetaceans may be a diving adaptation. Bone-enclosed air chambers are detrimental, as their rigid walls may fracture during descent/ascent due to contracting/re-expanding air volumes. Flexible-walled "sinuses" (extracranial diverticula) are a logical adaptation to diving. Odontocetes (toothed whales) exhibit several pairs of paranasal air sacs. Although fossil evidence indicates that paranasal sinuses occur in archaeocetes (ancestors/relatives of living cetaceans), it is not known whether the paranasal sacs derive from these sinuses. Sac pigmentation indicates that they derived from invaginations of the integument. Unlike sinuses, paranasal sacs are not circumferentially enclosed in bone, and therefore can accommodate air volume changes that accompany diving pressure changes. Paired pterygoid sacs, located ventrally along the cetacean skull, connect the pharynx and middle ear cavities. Mysticetes (baleen whales) have a large midline laryngeal sac. Although cetacean air sacs do not appear to be homologous to paranasal sinuses, they may serve some analogous respiratory, vocal, or structural functions. For example, these sacs may participate in gas exchange, thermoregulation, resonance, and skeletal pneumatization. In addition, they may subserve unique aquatic functions, such as increasing inspiratory volume, mitigating pressure-induced volume change, air shunting to reduce respiratory dead space, and facilitating underwater sound production and transmission.

    Objective Medial sphenoid wing meningiomas (SWMs) are relatively common tumors that are associated with significant morbidity and mortality, primarily from their anatomic proximity to many critical neurological and vascular structures. A major complication is visual deterioration. This study aimed to identify predictors of visual outcome following medial SWM resection. Design Retrospective, stepwise multivariate proportional hazards regression analysis. Setting Johns Hopkins Hospital. Participants All patients who underwent medial SWM resection from 1998 to 2009. Main Outcome Measures Visual function. Results Sixty-five medial SWM resections were performed. After multivariate proportional hazards regression analysis, preoperative visual decline (relative risk [RR] 95% confidence interval [CI]; 13.431 [2.601 to 46.077], p = 0.006), subtotal resection (RR [95% CI]; 3.717 [1.204 to 13.889], p = 0.02), and repeat surgery (RR [95% CI]; 5.681 [1.278 to 19.802], p = 0.03) were found to be independent predictors of visual decline at last follow-up. Tumor recurrence and postoperative radiation therapy trended toward, but did not reach statistical significance. Conclusion These findings advocate for early and aggressive surgical intervention for patients with medial SWMs to maximize the likelihood of subsequent visual preservation. This may provide patients and physicians with prognostic information that may guide medical and surgical therapy for patients with medial SWMs. PMID:24083123

    Objective To evaluate clinical characteristics and present surgical outcomes of PT caused by sigmoid sinus wall dehiscence (SSWD) Methods This study retrospectively reviewed 34 patients with PT who were diagnosed with SSWD in our institution between December 2008 and July 2013. Among them, 27 patients underwent sigmoid sinus wall reconstruction (surgery group) and 7 patients refused surgery (non-surgery group). Preoperative data were obtained from the patients’ medical records. All patients were followed up regularly for at least 25 months. Preoperative and postoperative computed tomography angiography (CTA) images were compared. Student’s t-tests were used to compare age, body mass index (BMI) and preoperative Tinnitus Handicap Inventory (THI) scores between the surgery and the non-surgery groups and to compare pre- and follow-up THI scores. Results There was no significant difference in age, body mass index, or preoperative THI scores between groups. Following surgery, 14 patients had complete resolution, 5 had partial resolution, 7 experienced no change and PT was aggravated in 1 patient. The difference between preoperative and postoperative THI scores was significant. No severe complications were found postoperatively. Comparison of the preoperative and postoperative CTA images revealed that remnant unrepaired dehiscences were the cause of unsatisfactory outcomes following surgery. In the non-surgery group, PT remained largely unchanged. Conclusions Sigmoid sinus wall reconstruction is an effective and safe treatment for PT caused by SSWD. It is imperative that all regions of the dehiscence are sufficiently exposed and resurfaced during surgery. PMID:27736970

    1988-01-01

    The arterial baroreceptors are known to be sensitive to changes in pressure but there are no known sensors in the cardiovascular system for changes in flow. We tested the hypothesis that changes in flow at constant pressure alter carotid sinus multi-unit nerve activity. In anesthetized dogs with vascularly isolated carotid sinuses, increases in flow at constant pressure resulted in increases in carotid sinus nerve activity in relation to the increase in flow. The increased activity during flow was not caused by an increase in strain of the sinus wall but was directly related to the increase in shear stress (36.6 +/- 11.7% increase in activity per dyne/cm2; 1 dyne = 0.1 MN). The pressure threshold of single baroreceptor units was determined during a slow pressure ramp with and without flow. Flow caused a significant decrease in pressure threshold from 81.1 +/- 6.1 mmHg (1 mmHg = 1.333 x 10(2) Pa) in the absence of flow to 69.3 +/- 5.7 mmHg with flow. We conclude that there are arterial "rheoreceptors" in the carotid sinus that respond to flow at constant pressure and strain. The results with single baroreceptor units indicate also that baroreceptors may be sensitized by increases in flow. Thus, changes in flow per se in addition to changes in arterial pressure may be important determinants of reflex circulatory adjustments. PMID:3174642

    2011-02-01

    We present two paediatric cases of fibrous dysplasia (FD) who presented to the craniofacial neurosurgical clinic with ophthalmological symptoms associated with sinus mucoceles. The first patient presented with a history of orbital cellulitis and an increasing bony swelling around the orbit associated with proptosis. Radiological imaging revealed monostotic FD associated with an obstructive mucocele in the frontal sinus with extension into the orbit. The second patient presented with recurrent conjunctivitis, painful proptosis, rhinitis and a bony peri-orbital swelling. Both patients had histological diagnoses of frontal mucoceles invading the orbit in association with FD. They both underwent frontal craniotomies and excision of the mucocele/fibrous dysplastic complex. In summary, mucocele development is an unusual complication of FD, likely to occur secondary to occlusion of the sinus drainage system. Orbital involvement may lead to visual disturbance caused by pressure effects. A multi-disciplinary approach including maxillofacial surgeons, plastic surgeons and neurosurgeons is advocated.

    . The vast majority of nasal concha mucosal samples of patients affected by chronic sinusitis presented with biofilm formation. Our study showed that 76.7 % of patients having FESS for CRS had evidence of biofilms on SEM micrographs. Although certain detection methods could lead to various discrepancies in the amount of biofilm produced, the consistent demonstration of biofilms in patients with CRS suggests that this convoluted three-dimensional structures might play a significant role in either the pathogenesis or persistence of chronic rhinosinusitis.

  15. Medical management of pediatric chronic sinusitis.

    PubMed

    Lippincott, L L; Brown, K R

    2000-10-01

    Pediatric sinusitis can be a challenging disease to treat, whether by a primary care physician or an otolaryngologist. When initial appropriate therapy fails to resolve the disorder, frustration may develop on the part of the patient, the family, and the physician. In addition to treatment with appropriate antibiotics for a sufficient length of time, other associated conditions that can exacerbate the condition must be considered and addressed as necessary. These may include viral upper respiratory infections, allergic rhinitis, immune deficiencies, asthma, and gastroesophageal reflux disease. Unless all associated conditions have been optimized, treatment of chronic sinusitis will often be unsuccessful. Recognition that there may be another factor contributing to the patient's continuing illness should prompt appropriate evaluation and occasionally referral to appropriate specialists. Except for the unusual pediatric patient with a truly anatomic disorder or an underlying chronic illness such as cystic fibrosis, proper medical management will almost always resolve chronic sinusitis.

    2011-01-01

    An increasing number of patients are opting for combining sinus surgery and cosmetic rhinoplasty. The author has been performing rhinoplasty with FESS since April of 1990. The technique and equipment used in early cases is much different than that used in more recent surgeries. Specific advances include high definition monitor, intraoperative navigation system, and powered dissecting instruments. The benefits of these advances are illustrated by a review of the more recent cases performed by the author. Combined rhinoplasty and FESS can be performed with good results (functional and cosmetic) and minimal complications. Advances in sinus surgery technique and equipment have made the procedure safer, faster, more precise, and more comfortable. PMID:22567242

    Cerebrospinal fluid hydrodynamics were investigated with a constant pressure infusion method in patients with superior sagittal sinus thrombosis. Ten patients were studied with serial examinations up to 15 years after the onset of the disease. A total of 70 CSF hydrodynamic examinations were performed. A clear increase in intracranial pressure due to raised pressure in the major dural sinus was seen in all patients. A striking feature was the persistent intracranial pressure increase that declined only gradually. This had no obvious clinical impact. Change in CSF resorption facility played only a minor role in the intracranial pressure elevation. None of the patients developed hydrocephalus. PMID:1583513

    Children have air-filled paranasal sinuses from birth. Acute sinusitis is common in early childhood and complicates 5-13% of common colds. Bacteriology comprises 30% Streptococcus pneumoniae, 20% Haemophilus influenzae, 20% Moraxella catarrhalis. While suppurative complications are rare, there has been an increasing focus on comorbidity affecting the lower airways (asthma). The diagnosis is based on clinical criteria developed through microbiological studies. Antibiotic treatment is controversial, but evidence suggests an effect when the diagnosis has been made correctly. We advocate antibiotic treatment in selected cases.

    On computed tomography, a mass-like density is often observed, just posterior to the ascending aorta, that occasionally has been mistaken for mediastinal lymph node enlargement. Cadaver studies confirmed this retroaortic structure to be an extension of the periocardial cavity, the superior sinus. Anatomic studies revealed the presence of a superior sinus in all of the 28 cadavers studied. Retrospective review of 116 consecutive adult chest computed tomographic examinations disclosed its presence in 49%. This normal variant has a characteristic location, shape, and attenuation value by CT that should allow recognition and prevent misinterpretation.

    Purpose Chronic maxillary atelectasis is characterized by unilateral spontaneous enophthalmos and hypoglobus due to increased orbital volume secondary to maxillary sinus inward deformation. Reformation of the sinus architecture and reconstruction of the orbit are key to a successful outcome. Here, we introduce a one-staged surgery that addresses both these goals. Patients and methods We retrospectively reviewed 11 patients treated with one-stage orbital and sinus surgery. A transconjunctival subperiosteal approach was used to create slats in the thinned orbital floor. A nasal endoscopic approach was utilized to access the maxillary sinus and place a modified Foley catheter balloon through the enlarged maxillary ostium. A bridge graft of nasal septal, ear cartilage, or LactSorb was placed on the reconstructed and balloon-supported orbital floor. The balloon was deflated and removed at 10–14 days. All patients underwent complete ophthalmic and orbital evaluation, including standardized photography and radiologic imaging. Results Eleven patients, mean age 39.5 years, presented with diplopia in upgaze, superior sulcus deformity, and at least 2 mm of relative enophthalmos. After initial overcorrection, enophthalmos improved in all cases. Symmetry within 1 mm was accomplished in 10 of 11 cases. Follow-up time was 259±320 days. Full motility was recovered in all patients. Conclusion We describe a one-staged surgery consisting of cutting slats in the orbital floor, dilating the maxillary sinus with a balloon, and stabilizing the orbital floor with a cartilage graft placement. Our anecdotal experience suggests that this surgical approach can safely achieve normalization of the pathologic sinus outflow and restoration of the orbit anatomy. The balloon ensures orbital floor stability during the healing process, and it may act to stent open the sinus ostium during early mucosal healing. PMID:27932858

    The purpose of this study is to describe the clinical and histopathological features, management and outcome of a series of patients with simultaneous occurrence of invasive and non-invasive fungal sinusitis (mixed fungal sinusitis). The histopathological records of patients with fungal sinusitis seen over the last 6 years were reviewed. The clinical, histopathological, treatment and follow up details of all cases with mixed fungal sinusitis were noted. Six cases of mixed fungal sinusitis with concurrent occurrence of chronic granulomatous fungal sinusitis and allergic fungal sinusitis (AFS) were seen during the study period. Most (83.3 %) had bilateral disease. All patients had undergone prior endoscopic sinus surgery at least once within the previous 2 years. Histopathological features showed predominance of invasive disease in half the patients. Except for one patient who did not report for follow up, all patients with predominant chronic granulomatous fungal sinusitis received systemic antifungal therapy and inhaled steroids. Those with predominant features of AFS received oral and inhaled steroids. Five patients with mixed fungal sinusitis who had follow up ranging from 6 months to 5 years were disease free following treatment. Mixed fungal sinusitis should be recognized by the surgeon and pathologist as a separate category of fungal sinusitis whose treatment depends on accurate histological diagnosis. A good outcome may be expected with appropriate therapy.

    SUMMARY We describe a case of traumatic intra-sphenoidal right internal carotid artery pseudoaneurysm lodged inside the fractured sphenoidal sinus that developed in a patient with a previous history of frontal and skull base fractures involving the sphenoid sinus and walls of the carotid canal, but with normal intracranial findings at early CT angiography. The patient presented two episodes of massive life-threatening delayed epistaxis before successful endovascular treatment combining the use of coils and an uncovered stent was instituted. This case report highlights that patients with head trauma who present sphenoid sinus fractures with or without massive epistaxis should be evaluated for the development of traumatic internal carotid artery pseudoaneurysm as soon as possible. If the first angiographic evaluation reveals normal findings, repeated epistaxis should prompt a second angiographic evaluation because psudoaneurysm takes time to develop. Early treatment with uncovered stent of the aneurysm can be a life-saving therapeutic approach. PMID:27196081

    Sinusitis is a common finding in avian species; however, it presents unique treatment challenges in ratites. A 6-yr-old male greater rhea ( Rhea americana ) presented acutely with right infraorbital sinus swelling and chemosis. Oral antibiotics were prescribed based on bacterial culture results with incomplete resolution of clinical signs. A computed tomography scan of the skull demonstrated a mixed-density soft tissue mass with extensive destruction of the right nasal bone, hard palate, maxilla, and frontal bone. The affected tissue was surgically resected and histopathology was consistent with inspissated necrotic tissue. Aerobic culture of the mass grew a multidrug-resistant Escherichia coli and was treated with amikacin. Ten months postsurgery, no further clinical signs were observed. Advanced diagnostic imaging with computed tomography and surgical therapy facilitated complete resolution of this resistant bacterial sinusitis in a species that is not typically amenable to frequent handling and restraint.

    Odontogenic Keratocyst (OKC) also termed as Keratocystic Odontogenic Tumour (KCOT) (WHO 2005) is a pathology with unique behavior because of which it is under much scrutiny and continued study. The pathology usually presents itself commonly in mandible and less commonly in maxilla. The occurrence of KCOT in maxillary sinus is reported as rare and multiple occurrences are mostly associated along with the presence of Nevoid Basal Cell Carcinoma (NBCC) syndrome. Here, we present a rare case of bilateral Maxillary OKC involving maxillary sinuses, without the presence of NBCC syndrome. An interesting feature of this case is the presence of left upper third molar in ectopic position in maxillary sinus and a vertically impacted right third molar suggesting an origin from the dental lamina.

    Nephrotic syndrome is associated with a hypercoagulable state and an increased risk of thromboembolic complications. Cerebral venous sinus thrombosis is a rare complication of nephrotic syndrome, with few cases described in the literature, although the disease may be under-diagnosis. The true incidence of cerebral venous sinus thrombosis may be underestimated because many events are asymptomatic or are not diagnosed in time. Here, we describe the case of a male child, 2 years and 10 months old, with nephrotic syndrome presenting with headache, epileptic seizures and sensory inhibition who was diagnosed with superior sagittal and transverse sinuses thrombosis. An international literature review was performed with a defined search strategy in the PubMed, SciELO and Lilacs databases using the terms 'nephrotic syndrome' and 'cerebral sinovenous thrombosis'. The diagnosis of venous thrombosis should be considered in any patient with nephrotic syndrome who presents with neurological signs and symptoms, as early clinical diagnosis promotes favorable outcomes.

    A pilonidal sinus is a chronic inflammatory process, the etiology of which is still not fully elucidated. It frequently presents at the sacrococcygeal region (typical) and rarely at extrasacrococcygeal (atypical) locations, including the interdigital, axillary, inguinal, and umbilical regions, as well as the neck, face, and scalp. A 46-year-old man presented with a thirty-year history of a slowly growing nodule on the postauricular area of the scalp. The lesion was excised and diagnosed as a pilonidal sinus based on the clinical and histological findings. The purpose of this review is to report the unusual occurrence of a pilonidal sinus on the scalp and to review the literature regarding this particular location of occurrence. PMID:28127490

    We present a case of isolated sinusitis sphenoidalis caused by Trichoderma longibrachiatum, an emerging causal agent of fungal infections with an often fatal outcome. A Trichoderma strain was isolated from secretion obtained from the sinus sphenoidalis of a rhinosinusitis patient and identified by sequence analysis of two loci as Trichoderma longibrachiatum from the Longibrachiatum Clade of the genus Trichoderma. T. longibrachiatum can trigger a fatal pathomechanism in immunodeficient patients, but only rarely causes disease in healthy people. The case presented is unique because the patient was not immunocompromised.

    Chronic rhinosinusitis is the most common chronic illness in the United States. An understanding of the anatomy of the paranasal sinuses, their functioning in health and in disease, and the contributing factors that are critical to the pathogenesis of rhinosinusitis is essential for nurses caring for patients with this prevalent disease. This paper will provide the otorhinolaryngology (ORL) nurse with an overview of the scientific principles important in rhinosinusitis, as well as presenting a framework for the understanding of rhinosinusitis and its treatment. (This paper is the first in a series of two articles. The second part will review the diagnosis and treatment of chronic rhinosinusitis.)

    We present the case of a 47-year-old man with exercise-induced dyspnea, cough, chest tightness, and recalcitrant chronic rhinosinusitis. Evaluation revealed IgE sensitization to grass, tree, and weed pollen, no evidence of obstruction on spirometry, and a negative methacholine challenge. Diagnostic considerations included allergic and nonallergic rhinitis, asthma, aspirin-exacerbated respiratory disease, vocal cord dysfunction, extra-esophageal manifestations of acid reflux, and vasculitits. Further evaluation with sinus imaging, laryngoscopy, ambulatory pharyngeal pH testing, upper endoscopy, and bronchoscopy led to a diagnosis. Key issues surrounding the diagnostic and therapeutic approaches to this patient's condition are reviewed.

  12. Acute otitis media and acute bacterial sinusitis.

    2011-05-01

    Acute otitis media and acute bacterial sinusitis are 2 of the most common indications for antimicrobial agents in children. Together, they are responsible for billions of dollars of health care expenditures. The pathogenesis of the 2 conditions is identical. In the majority of children with each condition, a preceding viral upper respiratory tract infection predisposes to the development of the acute bacterial complication. It has been shown that viral upper respiratory tract infection predisposes to the development of acute otitis media in 37% of cases. Currently, precise microbiologic diagnosis of acute otitis media and acute bacterial sinusitis requires performance of tympanocentesis in the former and sinus aspiration in the latter. The identification of a virus from the nasopharynx in either case does not obviate the need for antimicrobial therapy. Furthermore, nasal and nasopharyngeal swabs are not useful in predicting the results of culture of the middle ear or paranasal sinus. However, it is possible that a combination of information regarding nasopharyngeal colonization with bacteria and infection with specific viruses may inform treatment decisions in the future.

    Persistent mucosal inflammation, granulation tissue formation, hypersensitivity, and multifactorial infection are newly described complications of retained drug-eluting stents from endoscopic sinus surgery for refractory rhinosinusitis. In an important report published in Allergy and Rhinology, a 45-year-old male patient suffering from recalcitrant chronic rhinosinusitis underwent functional endoscopic sinus surgery and was found, for the first time, to have steroid-eluting catheters that were inadvertently left in the ethmoid and frontal sinuses. The retained catheters had caused persistent mucosal inflammation and formation of granulation tissue denoting hypersensitivity reaction. These consequences had induced perpetuation of symptoms of chronic rhinosinusitis. Meticulous removal of the retained stents with the nitinol wings from inflamed tissues of the frontal, ethmoidal, and sphenoethmoidal recesses in which they were completely imbedded was successfully performed without polypoid regrowth. Cultures of specimens taken from both left and right stents showed heavy growth of Stenotrophomonas maltophilia and moderate growth of Klebsiella oxytoca, coagulase negative Staphylococcus, and beta-hemolytic Streptococcus anginosus. Fungal infection was not detected. The current knowledge and experience regarding stent hypersensitivity and infection in relation with the use of stents in sinus cavities is reviewed. PMID:24498522

    Implant treatment in an atrophied edentulous posterior maxilla constitutes a challenge for the therapeutic team. The authors of the present study acknowledge that modern micro-rough surface implants in lengths of about 8-10 mm or longer and of different brands are similarly successful. Consequently, the authors propose that the use of different sinus floor elevation techniques should be considered when < 8 mm of bone is available below the maxillary sinus. The type of sinus floor elevation technique selected is mainly based on residual vertical bone height, marginal bone width, local intrasinus anatomy and the number of teeth to be replaced, although other factors (such as surgical training and surgical experience) may have an impact. It is proposed that a transcrestal sinus floor elevation approach can be considered as a first-choice method for single tooth gaps in situations with sufficient width for implant placement and a residual bone height of 5-8 mm, while lateral sinus floor elevation, with or without grafting materials, is indicated when < 5 mm of bone is available and when several teeth are to be replaced. With regard to time of implant placement, a one-stage procedure is preferred provided that high primary stability can be ensured.

    Background The aim of this study was to report the outcomes of powered endoscopic dacryocystorhinostomy (PEnDCR) in patients with lacrimal sac within the sinus. Materials and methods Retrospective analysis was performed on all patients who underwent PEnDCR and were intraoperatively documented to have complete lacrimal sac in sinus. Data collected included demographics, clinical presentations, associated lacrimal and nasal anomalies, intraoperative findings, intraoperative guidance, complications, postoperative ostium behavior, and anatomical and functional success. A minimum follow-up of 6 months postsurgery was considered for final analysis. Results A total of 17 eyes of 15 patients underwent PEnDCR using standard protocols, but with additional intraoperative guidance where required and careful maneuvering in the ethmoid sinus. The mean age of the patients was 37.2 (range 17–60) years. Of the unilateral cases, 69% (nine of 13) showed left-side predisposition; 80% of patients showed regurgitation on pressure over the lacrimal sac area. Associated lacrimal and nasal anomalies were observed in 13.3% (two of 15) and 40% (six of 15), respectively. At a mean follow-up of 6.6 months, anatomical and functional success were observed in 93.3% (14 of 15). One patient showed failure secondary to cicatricial closure of the ostium. Conclusion An entire sac within an ethmoid sinus poses a surgical challenge. Good sinus-surgery training, thorough knowledge of endoscopic anatomy, careful maneuvering, and use of intraoperative navigation guidance result in good outcomes with PEnDCR. PMID:27462137

    Sinus blockages are a common reason for physician visits, affecting one out of seven people in the United States, and often require medical treatment. Diagnosis in the primary care setting is challenging because symptom criteria (via detailed clinical history) plus objective imaging [computed tomography (CT) or endoscopy] are recommended. Unfortunately, neither option is routinely available in primary care. We previously demonstrated that low-cost near-infrared (NIR) transillumination correlates with the bulk findings of sinus opacity measured by CT. We have upgraded the technology, but questions of source optimization, anatomical influence, and detection limits remain. In order to begin addressing these questions, we have modeled NIR light propagation inside a three-dimensional adult human head constructed via CT images using a mesh-based Monte Carlo algorithm (MMCLAB). In this application, the sinus itself, which when healthy is a void region (e.g., nonscattering), is the region of interest. We characterize the changes in detected intensity due to clear (i.e., healthy) versus blocked sinuses and the effect of illumination patterns. We ran simulations for two clinical cases and compared simulations with measurements. The simulations presented herein serve as a proof of concept that this approach could be used to understand contrast mechanisms and limitations of NIR sinus imaging.

    A 64-year-old woman underwent right suboccipital craniotomy to treat spontaneous cerebrospinal fluid (CSF) otorrhoea. Although the CSF leak was cured, the patient developed pulsatile tinnitus, ambulatory disturbance and progressive dementia. Four years after the surgery, she presented with generalised seizure. Cerebral angiography showed a dural arteriovenous fistula at the right transverse-sigmoid sinus, which was associated with sinus occlusion, retrograde blood flow in the sinus and diffuse intracranial cortical venous reflux. A combination of endovascular transarterial embolisation and transvenous embolisation with direct sinus puncture was performed. After the procedure, the patient's mental status and cognitive function improved significantly.

    Our objective was to perform a systematic review of the literature on contemporary indications and outcomes for frontal sinus trephination and present an illustrative case of an endoscopically assisted repair of a subcutaneous frontal sinus fistula by trephination technique. PubMed and Ovid databases were used as data sources. A systematic review of the English literature was completed to review reports of frontal trephination from 1980 to 2014. Articles meeting inclusion criteria for inflammatory and noninflammatory indications were reviewed. Articles were systematically reviewed and graded by evidence-based medicine level. An illustrative case from our institution is then presented. The systematic review identified 2,621 published studies. Thirty-eight studies were identified for inclusion. The indications, techniques, outcomes, safety, and complications were reviewed for noninflammatory and inflammatory conditions. There were 32 retrospective case series, reports, or cohort studies (level 4), four systematic reviews (level 3), one prospective analysis (level 3), and one meta-analysis (level 2). Due to the heterogeneity of study cases and inclusion criteria, a meta-analysis was not feasible. We also present a novel closure of an anterior skull base defect resulting in a subcutaneous fistula with use of a frontal trephination approach. The frontal sinus trephination should not be regarded as a procedure of the past, as it useful in the armamentarium of the modern sinus and skull base surgeon. This approach provides access for instrumentation for hard-to-reach frontal sinus disease either purely through a trephination approach or as a supplementation to the transnasal endoscopic approach. Evidence supporting frontal sinus trephination is of levels 2, 3, and 4. Level of evidence: NA.

    A 76-year-old woman presented with an acute onset of right periocular pain, diplopia, ocular injection, progressive proptosis, and periocular swelling. She had an unremarkable past medical history, and the erythrocyte sedimentation rate and complete blood count were normal. A carotid-cavernous sinus fistula was suspected, and an MRI demonstrated enlargement of the superior ophthalmic vein posterior to the globe and enlargement of the inferior ophthalmic vein throughout its entire course. Cerebral arteriography demonstrated a dural cavernous sinus fistula. The inferior ophthalmic vein was accessed via the inferonasal orbital space and was catheterized for delivery of multiple platinum coils to the cavernous sinus fistula. Follow-up venograms demonstrated occlusion of the fistula. At 2-month follow-up, there was a residual sixth nerve palsy and resolution of symptoms, including proptosis and periocular swelling.

    Cerebral venous sinus thrombosis represents less than 1% of all strokes, being an uncommon entity with a wide spectrum of clinical scenarios. We present a 45-year-old Hispanic female with a history of long-term oral contraceptive use who was diagnosed with cerebral venous sinus thrombosis due to a heterozygous carrier mutation in the prothrombin G20210A gene. The patient was successfully managed with intravenous heparin with favorable clinical results without adverse effects. The prevalence of inherited primary thrombophilia increases with additional risk factors such as the use of oral contraceptives that can trigger or prothrombotic events in any vascular bed. An increased prevalence in the prothrombin G20210 gene mutation has been demonstrated in the Mexican-Mestizo population. Controversy exists regarding therapy of cerebral venous sinus thrombosis; according to experts, heparin remains the cornerstone of therapy with acceptable outcomes. More clinical trials are required to evaluate long-term outcomes in this subgroup of patients.

    We report a contained rupture of a right coronary sinus of Valsalva aneurysm, in which repair resulted in symptomatic improvement. Patients often present with symptoms secondary to rupture of the sinus of Valsalva aneurysm into one of the cardiac chambers, or secondary to the compression of adjacent structures. Whereas sinus of Valsalva aneurysms and their rupture are well reported in the literature, contained ruptures have been described only rarely. In those cases, symptoms often arose from compression of adjacent structures. Although transesophageal echocardiography is considered to be the diagnostic method of choice, cardiac magnetic resonance imaging and computed tomography can be equally helpful in establishing the diagnosis and delineating the lesion. Diagnosis and prompt repair in our 64-year-old patient resulted in the rapid resolution of his symptoms. PMID:27777531

    Introduction: Invasive aspergillosis of the paranasal sinuses is a rare disease and often misdiagnosed; however, its incidence has seen substancial growth over the past 2 decades. Definitive diagnosis of these lesions is based on histological examination and fungal culture. Case Report: An 81-year-old woman with a history of pain in the left maxillary region is presented. The diagnosis was invasive maxillary aspergillosis in immunocompetent patient, which was successfully treated with voriconazole and surgical debridement. Possible clinical manifestations, diagnostic imaging techniques and treatment used are discussed. Since the introduction of voriconazole, there have been several reports of patients with invasive aspergillosis who responded to treatment with this new antifungal agent. Conclusions: We report the importance of early diagnosis and selection of an appropriate antifungal agent to achieve a successful treatment. Key words:Invasive aspergillosis, voriconazole, fungal sinusitis, antifungal agent, open sinus surgery. PMID:25593673

    2016-05-01

    Traumatic globe dislocation into the paranasal sinuses is rare. Only 24 cases have been reported in the English-language literature indexed in PUBMED. This form of injury frequently occurs as a result of high-energy blunt trauma mainly associated to traffic accidents. Traumatic globe dislocation into the paranasal sinuses can be explained by the mechanism of blowout fracture when strong blunt trauma forces are applied to the globe fracturing the thin orbital walls and displacing the eyeball. Medical and surgical management of severe globe displacement is still controversial. However, the majority of researchers agreed that the globe should be replaced into the orbital cavity as soon as possible. The present study aims to describe a case of traumatic globe dislocation into the maxillary sinus suggesting treatment guidelines based on English-language literature from 1971 to 2015.

    The pneumatization of the maxillary sinus often results in a lack of sufficient alveolar bone for implant placement. In the last decades, maxillary sinus lift has become a very popular procedure with predictable results. Sinus floor augmentation procedures are generally carried out using autologous bone grafts, bone substitutes, or composites of bone and bone substitutes. However, the inherent limitations associated with each of these, have directed the attention of investigators to new technologies like bone tissue engineering. Bone marrow stromal cells have been regarded as multi-potent cells residing in bone marrow. These cells can be harvested from a person, multiplied outside his body using bioengineering principles and technologies and later introduced into a tissue defect. We present a case where tissue-engineered autologous osteoblasts were used along with demineralized freeze-dried bone for sinus floor augmentation. PMID:26097364

    We report a case of cryptococcal sinusitis, a rare presentation of Cryptococcus neoformans infection in a patient with multiple myeloma. The objective of this case report is to highlight the utility of structural and functional imaging modalities in the differential diagnosis of sinonasal soft tissue masses in the immunocompromised patient population. PET-CT was the first imaging modality in this patient, who presented for routine follow-up staging of multiple myeloma, and was asymptomatic at the time of his presentation. PET-CT findings prompted further evaluation with MRI, to aid in the differential diagnosis with respect to a neoplastic versus infectious etiology. Ultimately, surgical excision with histopathology was required to provide definitive diagnosis. Final histopathology displayed yeast-organism staining consistent with Cryptococcus neoformans/gatti. The patient subsequently underwent treatment for this infection, along continued treatment for multiple myeloma. To our knowledge this is the first known case of cryptococcal sinusitis in a patient with neoplastic disease. Imaging represents an important tool to differentiate fungal infection from neoplasm in the immunocompromised patient population. As the population of immunocompromised patients continues to grow, the relevance of this diagnosis as well as the use of alternative imaging modalities is becoming more important in clinical practice.

    Invasive fungal rhinosinusitis is a potentially fatal infection that affects immunocompromised patients. Prognosis is generally poor despite aggressive medical and surgical treatments. We present the first reported case of invasive fungal sinusitis in a healthy 18-year-old male athlete who was taking anabolic androgenic steroids (AAS). The effects of excessive AAS use on the immune system are not fully understood, but there may be consequences at supraphysiological concentrations. This case demonstrates potential immunomodulatory effects of anabolic steroids and highlights a previously unknown cause of invasive fungal sinusitis.

    Postdural puncture headache (PDPH) is a feared complication related to epidural steroid injections. We report a unique case in which all subjective and objective findings indicated the diagnosis of PDPH. However, the patient failed appropriate conservative and interventional management. Therapeutic failure prompted further investigation to establish the correct diagnosis of cerebral venous sinus thrombosis. Cerebral venous sinus thrombosis is a rare, difficult to diagnose, but potentially lethal disorder with nonspecific and variable clinical presentations, including headache and focal neurological deficits. Performing magnetic resonance imaging and magnetic resonance venogram should be considered early, especially in patients who fail to respond to standard interventions for PDPH.

    Fibrin glue injection has been used to control intraoperative cavernous sinus (CS) venous bleeding. There have been no reported complications related to this maneuver. We present a case where a patient developed a sensory trigeminal nerve deficit after injection of fibrin glue into the posterior CS during resection of a petrosal meningioma. We believe that this deficit was due to the compression of the trigeminal ganglion similar to balloon compression procedures. Although fibrin glue injection may achieve satisfactory cavernous sinus homeostasis, the volume and rate of injection should be kept in mind to avoid a compressive lesion on traversing cranial nerves and surrounding structures, or retrograde filling of the venous tributaries.

    Background Transgenic cystic fibrosis (CF) murine models do not develop spontaneous lung or sinus disease, two major causes of morbidity in human CF patients. Because of these limitations, transgenic CFTR−/− pigs have been developed and are currently being characterized. These CF animal models have phenotypes closely resembling that of human CF subjects. The objectives of the current study were to develop primary porcine nasal epithelial (PNE) cultures and evaluate their usefulness as a means to investigate sinonasal transepithelial transport and CFTR function. Methods PNE derived from the septum or turbinates of CFTR+/+ and CFTR−/− pigs were cultured at an air-liquid interface to confluence and full differentiation. Epithelial monolayers were mounted in Ussing chambers to investigate pharmacologic manipulation of ion transport. Ciliary beat frequency (CBF) and scanning electron microscopy of monolayers were used to indicate degree of ciliation and cell differentiation. Results Stimulation of CFTR-mediated anion transport(ΔIsc in μA/cm2) was significantly greater in epithelia derived from the septum when compared to turbinates(33.04+/−1.17 vs. 18.9+/−0.73;p<0.05). cAMP-activated Cl− secretion was absent in CFTR−/− and present in CFTR+/+ epithelia. Calcium-activated Cl− (CaCC) secretion was increased in CF, however, overall Cl− transport through CaCCs was very low. Degree of ciliation (90%) and CBF were similar between groups. Discussion Septal PNE exhibit a robust ion transport phenotype and indicate CFTR−/− sinus disease could be attributable to diminished alternative pathways for Cl− transport. Overall, PNE have similarities to human respiratory epithelia not demonstrated in murine cells and represent useful in vitro models for studying CF sinus disease. PMID:24733748

    Anterior cervical discectomy/corpectomy and fusion is performed in degenerative, traumatic and neoplastic etiologies of the cervical spine. This procedure is highly successful and associated with fewer complications. The rates of early and late postoperative infection have been reported to be between 0.1% and 1.6%, the late infections are being very rare. We report a rare case of a 30-year-old HIV negative, non-diabetic male who developed a late prevertebral cervical abscess with discharging sinus over posterior triangle of neck 3 years after an anterior cervical C6 corpectomy with fibular grafting and buttress screw fixation performed elsewhere for traumatic fracture C6 vertebra. The abscess was drained using radical neck dissection approach with complete excision of sinus track and removal of the infected implant. On culture, the organism was found to be beta-hemolytic streptococci, for which appropriate antibiotics were administered postoperatively. The sinus tract completely healed in 3 months time. Late infection as a complication of anterior cervical spine surgeries is rare and is associated with esophageal perforation, implant migration, seeding of the deep prevertebral space with oropharyngeal flora, or from surgical site/bacteremia or with Zenker's diverticulum. Few cases have been reported till date, but none have presented with a sinus tract. We present a case of delayed prevertebral abscess after cervical spine instrumentation that followed abnormal path causing sinus track to be developed in the site (the posterior triangle of the neck) other than previous incision site. Exploring both triangles of the neck using radical neck dissection approach was essential for complete excision of sinus track, removal of screw and debridement.

    Cavernous sinus hemangioma (CSH) is a rare extra-axial vascular neoplasm that accounts for 2% to 3% of all cavernous sinus tumors. Their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures are factors which present difficulty in excising these lesions. The authors describe their experience of 22 patients with CSH over 14 years at a tertiary care center. Patients were managed with microsurgical resection using a purely extradural transcavernous approach (13 patients) and with Gamma Knife radiosurgery (GKRS; Elekta AB, Stockholm, Sweden) (nine patients). Retrospective data analysis found headache and visual impairment were the most common presenting complaints, followed by facial hypesthesia and diplopia. All but one patient had complete tumor excision in the surgical series. Transient ophthalmoparesis (complete resolution in 6-8 weeks) was the most common surgical complication. In the GKRS group, marked tumor shrinkage (>50% tumor volume reduction) was achieved in two patients, slight shrinkage in five and no change in two patients, with symptom improvement in the majority of patients. To our knowledge, we describe one of the largest series of CSH managed at a single center. Although microsurgical resection using an extradural transcavernous approach is considered the treatment of choice in CSH and allows complete excision with minimal mortality and long-term morbidity, GKRS is an additional tool for treating residual symptomatic lesions or in patients with associated comorbidities making surgical resection unsuitable.

    The frontal sinus is a sturdy part of the skull that is likely to be retrieved for forensic investigations. We evaluated frontal sinus parameters in paranasal sinus computed tomography (CT) images for sex determination. The study was conducted on 200 normal paranasal sinus CT images of 100 men and 100 women of Persian origin. We categorized the studied population into three age groups of 20-34, 35-49 and ⩾ 50 years. The number of partial septa in the right frontal sinus and the maximum height and width were significantly different between the two sexes. The highest precision for sex determination was for the maximum height of the left frontal sinus (61.3%). In the 20-34 years age-group, height and width of the frontal sinus were significantly different between the two sexes and the height of the left sinus had the highest precision (60.8%). In the 35-49 years age-group, right anterior-posterior diameter had a sex determination precision of 52.3%. No frontal sinus parameter reached a statistically significant level for sex determination in the ⩾ 50 years age-group. The number of septa and scallopings were not useful in sex determination. Frontal sinus parameters did not have a high precision in sex determination among Persian adults.

    Fulminant aspergillosis was diagnosed on nasal biopsy in a 49 year old man who had features of an aspergilloma. Further postmortem examination of this area was performed and the results were contrasted with the histological features of other Aspergillus infections. The nasal biopsy specimen and postmortem examination showed infiltrating Aspergillus hyphae with tissue necrosis and little inflammatory response. The hyphae were easily seen with routine stains. This contrasts with the findings in invasive aspergillosis where there is fibrosis and a granulomatous response to the Aspergillus hyphae. The hyphae are seen in giant cells using fungal stains. In the saprophytic infections aspergilloma and allergic Aspergillus sinusitis there is no tissue invasion or destruction. Aspergillus infections of the nose and paranasal sinuses often require biopsy for accurate diagnosis. As treatment varies pathologists need to be able to distinguish the different patterns of infection. Images Fig 1 Fig 2 Fig 3 Fig 4 Fig 5 PMID:2921352

    Cavernous sinus syndrome (CSS) is a rare condition characterised by ophthalmoplegia, proptosis, ocular and conjunctival congestion, trigeminal sensory loss and Horner’s syndrome. These signs and symptoms result from the involvement of the cranial nerves passing through the cavernous sinus. We report the case of a 53-year-old man with a history of daily stabbing headache associated with dizziness, progressive blurred vision, right ocular pain, ptosis and ophthalmoplegia. After working up the patient, a meningioma was identified as the cause of the CSS. Despite advances in neuroimaging techniques, in some cases, the aetiology of CSS remains difficult to determine. We highlight the clinical and radiological features of a meningioma, one of the causes of CSS. Early diagnosis and treatment of CSS play a key role in a better prognosis. PMID:25819816

    In the present study, we investigated the efficacy of local anesthetics soaked non-absorbable sinus packs on pain management after functional endoscopic surgery (FESS). One hundred and fifty patients with the diagnosis of bilateral chronic sinusitis with or without nasal polyps who underwent FESS were included into the study. Their pre-operative Lund-Mackay computerized tomography (CT) Scores were similar. We applied anesthetic agents of 2 % lidocaine HCl, 0.25 % Bupivacaine HCl, 0.2 % Ropivacaine, 2 % Prilocaine and 0.9 % NaCl (Saline) in groups 1-5 onto the sinus packs after FESS. At postoperative period, acetaminophen (250 mg/5 ml) was used in 10-15 mg/kg per dose (4 times a day). Bleeding grade, operation duration, postoperative number of gauze/24 h, additional painkiller need, pain values at 1, 2, 4, 8, 12 and 24 h were noted. Lund-Kennedy endoscopic scores were also evaluated at 1st, 2nd and 4th weeks postoperatively. In saline group, 93.3 % of the patients needed additional painkiller. Whereas, in Bupivacaine group, additional painkiller use (20.0 %) is less than the other groups. In Bupivacaine group, number of gauze/24 h use was lower than lidocaine, ropivacaine and prilocaine groups. In our study, except 1st and 24th hours, pain values of groups can be written in ascending order (from less to higher) as Bupivacaine, Lidocaine, Prilocaine, Ropivacaine and Saline. In the first hour, pain values of groups can be written in ascending order (from less to higher) as Lidocaine, Prilocaine, Bupivacaine, Ropivacaine and Saline. In the 2nd week, in the Bupivacaine and Lidocaine Groups separately, postoperative Lund-Kennedy scores were lower than the Prilocaine and Saline Groups. In the 1st month, Lidocaine Group's Lund-Kennedy scores were significantly lower than the Saline Group. Synechia values were not different between groups. Bupivacaine help the lower pain values and less additional painkiller need after FESS. Therefore, we recommend to use

    Conditions of the head requiring surgery in cattle are not uncommon when considering the incidence of conditions such as ocular squamous cell carcinoma and requests for surgical dehorning. Surgery involving the eyes in cattle is relatively common, whereas surgery of the paranasal sinuses is less common. Generally speaking, however, surgery for conditions of the head tend to have a more favorable prognosis when there is early intervention.

    Anatomical complexity presents the main challenge in the administration of topical corticosteroid therapy to the paranasal sinus mucosa. This often leads to suboptimal drug delivery due to low concentrations of the therapeutic agent to the intended target area. The Relieva Stratus™ MicroFlow Spacer (Relieva Stratus) is a drug-eluting stent that is temporarily implanted into the ethmoid sinus. The reservoir of the stent is filled with triamcinolone acetonide, which is then slowly released from the device into the ethmoid sinus mucosa. The Relieva Stratus provides local and targeted delivery of the anti-inflammatory agent to the diseased mucosa. This minimally invasive implant is an option when treating ethmoid sinusitis. From January 2011 to November 2013, a total of 52 Relieva Stratus implantations into the ethmoidal cells were performed at the Department of Ear and Oral Diseases at Tampere University Hospital, Finland. C-arm fluoroscopy guidance was employed for 26 sinuses (13 patients) and optical image-guided surgery (IGS)-assisted insertions were performed on another 26 sinuses (13 patients). The accuracy of fluoroscopic insertion is not optimal, but this method is accurate enough to prevent the violation of the skull base and lamina papyracea. IGS enables the precise treatment of the diseased cells. From a technical perspective, IGS-guided insertion is a faster, safer and more exact procedure that guarantees the optimal positioning and efficacy of the implant. Moreover, IGS guidance does not entail the use of ionizing radiation.

    Background Clinical data of 288 chronic rhinosinusitis patients were retrospectively analyzed to investigate the risk factors of clinical prognosis, aiming to provide clinical evidence for the diagnosis and treatment of chronic rhinosinusitis. Material/Methods A total of 288 patients diagnosed with chronic rhinosinusitis in the Department of Otolaryngology of the First Affiliated Hospital of Xinjiang Medical University were recruited. Among all participants, 177 were male and 111 were female, aged from 22 to 83 years, (52±14) years on average. Subsequent follow-up was conducted to evaluate surgical efficacy. Influencing factors of clinical prognosis were analyzed by univariate and multivariate logistic regression analyses. Results After functional endoscopic sinus surgery by Messerklinger technique, 187 (64.9%) patients were fully recovered, 72 (25.0%) presented with improvement, and 28 (10.1%) were untreated. Univariate logistic regression analysis revealed that 11 variables were correlated with the clinical prognosis of chronic rhinosinusitis. Multivariate logistic regression analysis demonstrated that age, history of allergic rhinitis, severity of dysosmia, history of nasosinusitis surgery, and long-term use of nasal decongestant were the risk factors, whereas comprehensive therapy after surgery was a protective factor. Conclusions More emphasis should be placed upon the factors associated with the clinical prognosis of patients with chronic rhinosinusitis following undergoing endoscopic sinus surgery, offering consolidated evidence for the prevention and treatment of chronic rhinosinusitis.

    The computed tomographic (CT) findings of fungal rhinitis/sinusitis in cats were characterized. The CT images of 10 cats ranging in age from 7 to 13 years were examined. The mean age was 10.8 years and all were neutered males. Nasal aspergillosis was diagnosed in five cats, cryptococcosis in three cats, hyalohyphomycosis in one cat, and trichosporonosis in one cat. Bilateral disease was present in eight cats, seven had abnormal soft tissue attenuation in two-thirds of the nasal cavity, and six had turbinate lysis. Seven cats had also lysis of the hard palate, nasal septum, or frontal bone. One cat had lysis of the cribriform plate. Five of the nine cats whose lymph nodes were imaged had lymph node enlargement. There was contrast medium enhancement in the nasal cavity in all cats, with either a primarily peripheral rim or heterogeneous pattern. There appears to be an overlap of clinical signs, age, and CT features of cats with nasal neoplasia and those with fungal rhinitis/ sinusitis.

    The objective of the present study was to compare the efficacy of functional endoscopic dilatation sinus surgery (FEDS) with functional endoscopic sinus surgery (FESS) in treatment of chronic rhinosinusitis in patients who failed medical therapy. We enrolled 24 patients suffering with chronic rhinosinusitis, who failed medical treatment and were proceeding to surgery, in a prospective, randomized controlled pilot study carried out between January and December 2008 following ethical committee approval. All patients completed sino-nasal outcome test (SNOT)-20 questionnaires and underwent saccharine test preoperatively and 24 weeks post operatively. Only trained surgeons performed surgery. The SNOT-20 questionnaire and saccharine clearance time (SCT) were used to measure outcomes. The SNOT-20 scores for both patient groups showed similar, consistent symptomatic improvement compared with baseline measures. SCT was reduced in both groups. No significant post-operative complications were recorded in either group. No patient in the FEDS group had any bleeding, and all were ready for discharge within hours of the procedure. Thus, FEDS is as effective as FESS in treatment of chronic rhinosinusitis. It is can be considered an additional tool in endoscopic surgery and has the potential to be undertaken as a day procedure.

  5. Coronary Flow Impacts Aortic Leaflet Mechanics and Aortic Sinus Hemodynamics.

    2015-09-01

    Mechanical stresses on aortic valve leaflets are well-known mediators for initiating processes leading to calcific aortic valve disease. Given that non-coronary leaflets calcify first, it may be hypothesized that coronary flow originating from the ostia significantly influences aortic leaflet mechanics and sinus hemodynamics. High resolution time-resolved particle image velocimetry (PIV) measurements were conducted to map the spatiotemporal characteristics of aortic sinus blood flow and leaflet motion with and without physiological coronary flow in a well-controlled in vitro setup. The in vitro setup consists of a porcine aortic valve mounted in a physiological aorta sinus chamber with dynamically controlled coronary resistance to emulate physiological coronary flow. Results were analyzed using qualitative streak plots illustrating the spatiotemporal complexity of blood flow patterns, and quantitative velocity vector and shear stress contour plots to show differences in the mechanical environments between the coronary and non-coronary sinuses. It is shown that the presence of coronary flow pulls the classical sinus vorticity deeper into the sinus and increases flow velocity near the leaflet base. This creates a beneficial increase in shear stress and washout near the leaflet that is not seen in the non-coronary sinus. Further, leaflet opens approximately 10% farther into the sinus with coronary flow case indicating superior valve opening area. The presence of coronary flow significantly improves leaflet mechanics and sinus hemodynamics in a manner that would reduce low wall shear stress conditions while improving washout at the base of the leaflet.

    In a mixed sex sample of ten adult gibbon (Hylobates moloch) skulls, one cranium of a male with maxillary sinus atelectasis of the left side was identified. While external inspection revealed a slight drop of the left orbital floor, serial coronal computer tomography (CT) scans show characteristic changes of the left maxillary sinus and its surrounding structures. In addition to the sunken orbital floor, radiological features of the specimen include an inward bowing of the medial sinus wall, sinus opacification, and a reduction in maxillary sinus size to a slit-like cavity, which suggest a diagnosis of silent sinus syndrome. This report is the first, to our knowledge, of maxillary sinus atelectasis in a non-human primate. This finding is valuable for the understanding of the pathogenesis and etiology of maxillary sinus atelectasis. At the same time, however, paleoanthropologists and primatologists may refer to this information when dealing with the interpretation of maxillary sinus pneumatization of partially broken archaeological and fossil skulls.

    Contemporary endonasal sinus surgery has given rise to distinct extended procedures focusing on the frontal sinus. However, surgical results sometimes are flawed, with reactive scarring leading to a relapse of insufficiency of drainage and ventilation. Topical application of medicines may offer help, but the hidden operative field around the frontal sinus is not reached by the usual nasal drugs. The effectiveness of an intraoperative insertion of stents is still a subject of debate in the literature. In previous studies we have seen some positive results. Based on this fact we looked for additional modalities to boost the effectiveness of fronto-nasal stents. We present a new device acting both as a stent and also as a local drug-releasing system. The combination of two therapeutic modalities may improve our treatment results in endonasal frontal sinus surgery. The pharmaceutical basics of our device are presented, and the first clinical data are shown. The first clinical trial was completely successful. Modification of the polymer and also of the released pharmaceutical agents may provide future improvements and may allow additional applications of the system in other areas of our surgical specialty.

    Summary Introduction: Fungal ball of the sinuses is a not invasive infection that if characterizes for its chronicity, being the majority related with previous endodontic treatment. Affect mainly the breasts to maxillary; even so all the breasts can be involved. The main etiological agent is the Aspergillus spp. The computed tomography, had to characteristic the radiological presentations, suggests the diagnosis that is carried through definitively through histopathological analyses. The treatment standard-gold is the sinus surgery with average meatal antrostomy. Objective: Reporting two cases of fungal ball of the sinuses and to stand out important aspects of this pathology. Story of the Cases: Case 1) Patient of the feminine sex, 78 years old, presented itself with complaints of face pain has 6 months and previous history of endodontic treatment. To the physical examination it was evidenced purulent secretion presence in left average meatus. Ray X presented complete veiling of the breasts to maxillary left, while the computed tomography showed injury calcified in this place. Sinusotomy was become fulfilled that evolved well. Case 2) Patient of the feminine sex, 70 years old, looked attendance for history of sinusitis of repetition. To the physical examination no particularity was not perceived. The computed tomography, as well as the magnetic resonance, detected thickening of the mucous wall of the breasts to maxillary left, beyond a calcified mass. It was become fulfilled same sequence of treatment and the patient also evolved well. Final Considerations: The fungal infection must be considered in the patients who if present with chronic sinusitis, that they do not answer to the antibiotic use and that they possess history of endodontic manipulation.

    Pilonidal carcinoma is an infrequent complication of pilonidal disease. The surgeon's suspicion should be raised in cases of longstanding pilonidal inflammation. The disease occurs most frequently in men. The lesion is often a well-differentiated squamous carcinoma. Wide excisions at the initial procedure following a brief period of local wound care, is the optimum treatment and increases the chances for a five-year survival. Definitive closure of the defect is delayed and accomplished by rotational flaps or skin grafts. It palpable nodes are present in the inguinal region they should be biopsied even though this does not necessarily connote metastasis. When inguinal node metastasis is present, this is associated with a poor prognosis. The incidence of occult node metastasis is not known because no prophylactic groin dissections were performed. Staged groin dissections were not associated with any long-term survivals. The series was too small to determine its palliative potential. Radiation therapy may palliate local bone or soft tissue recurrences. Re-excisions of local soft tissue recurrences can provide, in some instances, long disease-free intervals. Both topical and systemic chemotherapy were administered in more recent cases with poor results, but this series is not large enough to form conclusions for this modality of treatment. Images Fig. 1.

    We present an automatic segmentation and statistical shape modeling system for the paranasal sinuses which allows us to locate structures in and around the sinuses, as well as to observe the variability in these structures. This system involves deformably registering a given patient image to a manually segmented template image, and using the resulting deformation field to transfer labels from the template to the patient image. We use 3D snake splines to correct errors in this initial segmentation. Once we have several accurately segmented images, we build statistical shape models to observe the population mean and variance for each structure. These shape models are useful to us in several ways. Regular registration methods are insufficient to accurately register pre-operative computed tomography (CT) images with intra-operative endoscopy video of the sinuses. This is because of deformations that occur in structures containing erectile tissue. Our aim is to estimate these deformations using our shape models in order to improve video-CT registration, as well as to distinguish normal variations in anatomy from abnormal variations, and automatically detect and stage pathology. We can also compare the mean shapes and variances in different populations, such as different genders or ethnicities, in order to observe differences and similarities, as well as in different age groups in order to observe the developmental changes that occur in the sinuses.

    A 55-year-old woman presented with a right trigeminal dysfunction (dysesthesia) initially, followed by right oculomotor and abducens paresis lasting 1 month. Neuroimaging studies showed an enhanced mass in the right cavernous sinus extending to the trigeminal ganglion. The extraparenchymal tumor located around the right trigeminal ganglion was totally removed, except for an intracavernous lesion, by the orbitozygomatic approach. The solid tumor was completely separated from the brainstem and seemed to be a trigeminal schwannoma arising from the trigeminal ganglion or cavernous sinus at surgery. A histological examination, however, found a typical malignant glioma that consisted primarily of astrocytic tumor cells. Immunohistochemical staining showed the tumor cells stained intensely for GFAP, S-100 protein, and vimentin, but not for NFP, Schwann/2E, CD34, and CD68. The mean MIB-1 index was 12.4%. The tumor recurred after a short time, and then it rapidly disseminated into the subarachnoid space and left the cerebral hemisphere. The patient died 1 year after the initial symptoms in spite of aggressive surgery, radiation, and chemotherapy with temozolomide. There are no previous reports of a malignant glioma arising from either the cavernous sinus or the trigeminal ganglion. From the pathogenetic point of view, this malignant glioma is an extremely rare case that developed clinically and neuroradiologically from the cavernous sinus and was suspected be being derived from ectopic glial tissue.

    A 10-year-old male neutered mixed breed dog was evaluated for cervical hyperesthesia and tetraparesis. Magnetic resonance imaging of the brain and cervical spinal cord identified an extradural compressive lesion over the body of C2 caused by marked dilation of the vertebral venous sinuses. Following intravenous contrast administration both vertebral sinuses had heterogeneous contrast enhancement consistent with incomplete thrombi formation. An abdominal ultrasound also showed a distal aortic thrombus. A definitive cause for the thrombi formation was not identified, but the patient had several predisposing factors which may have contributed. The patient was treated with a combination of warfarin, clopidogrel, and enoxaparin as well as analgesics. Within 48 h of initiation of warfarin therapy, the tetraparesis and hyperesthesia were markedly improved. Repeat abdominal ultrasound 3 weeks after discharge showed reduction in size of aortic thrombus. Neurologic function remained normal for 6 weeks following initiation of treatment. Seventy-four days following initial diagnosis the patient rapidly declined and passed away at home. Necropsy was declined. This is the first report of vertebral venous sinus enlargement leading to spinal cord compression and tetraparesis in a dog. Additionally, warfarin in combination with clopidogrel and enoxaparin appeared to be a safe and effective treatment for the suspected thrombi reported in this case. Vertebral sinus enlargement secondary to thrombi should be considered as a differential diagnosis in patients presenting with tetraparesis and cervical hyperesthesia. PMID:28229071

    Surgical treatment of the frontal sinus continues to be an area of much interest and controversy. The complex anatomy and confined space of this region require the endoscopic surgeon to be knowledgeable and delicate to obtain a positive result. Proper instrumentation is crucial and continues to evolve over time. Postoperative endoscopic care is integral to the success of endoscopic frontal sinusotomy and the availability of proper office equipment to perform this care is critical. In most instances, the intranasal endoscopic approach can be accomplished successfully without the need for an external procedure.

    Objective: Pituitary adenomas invading the cavernous sinus represent a therapeutic challenge. Those tumors have been traditionally treated with incomplete surgical removal, observation and/ or adjunctive medical therapy, and radiotherapy. In relatively recent years, some authors have suggested a main direct surgical approach to cavernous sinus (CS) with the aim of complete removal of the adenoma, either by a modified trans-sphenoidal route, using or not an endoscopy-assisted approach, or by a transcranial direct approach. The latter has the advantage of allowing direct exposure of the lesion with a view of the surgical field unhindered by important neurovascular structures. Materials and Methods: We report a technical modification of the classical epidural approach for CS adenoma removal. This was used in 14 patients. Surgical technique included a fronto-orbito-zygomatic craniotomy with extradural anterior clinoidectomy, and intradural approach to the Hakuba’s triangle for intracavernous dissection. The tumors were removed under direct vision. Results: Total macroscopical removal was achieved in all but one case. This patient required postoperative radiation therapy as well as adjuvant dopaminergic regime for achieving control of preoperatively increased hormonal values. No other case required radiotherapy. Hormonal and/ or clinical control was also achieved in all the remaining cases. Out of the remaining 13 cases, all appeared to be tumor free at an average postoperative observation at 78 months (34 to 90 months). Significant surgical sequels were detected in only 1 case (persistent 3rd nerve palsy and moderate hemiparesis). Conclusions: This experience, though limited, would suggest that the transcranial limited CS exposure through the Hakuba’s triangle may allow adequate removal of intracavernous pituitary adenomas with very good long-term results and acceptable complication rate.

    Fourteen cases of intestinal-type adenocarcinomas (IADC) of the nasal cavity and paranasal sinuses were studied at the Regional Hospital of Varese during the period from 1973 to 1988. They were 13 males and 1 female, mean age 57.5 years; the five year survival was 25% and tumors were preferentially located in the ethmoidal sinus. Morphological study and the use of monoclonal and polyclonal antibodies made it possible to define the structural features of IADC and to detect specific antigenic markers such as CAR-5 (a glycoprotein contained within intestinal goblet-cells) and M1 (a glycoprotein contained within gastric foveolar cells). For comparison 10 cases of colonic adenocarcinomas and 14 cases of non-AIDC carcinomas of the nose and paranasal sinuses were also examined. The parallel morphological and immuno-histochemical investigations based on specific markers demonstrated that it was impossible to differentiate IADC from large bowel adenocarcinoma for both the structural pattern and antigenic expression. Moreover, AIDC also showed a CAR-5 and M1 immunoreactivity (IR) different from that displayed by the nasal carcinomas of different histotypes. From a histopathological standpoint IADC appears to be a distinctive entity even when compared to salivary gland tumors. In addition, the present immunohistochemical investigation demonstrates that gastric and intestinal glycoproteic antigens (M1 and CAR-5 respectively) occur in the normal nasosinusal mucosa. Both CAR-5 and M1 were observed in the mucous produced by nasal goblet cells with a distribution pattern resembling that of colonic goblet cells. Therefore, the present data confirm the similarity between nasal and colonic goblet cells which has already been pinpointed in previous morphological and ultrastructural studies. The common antigenic expression shared by the naso-sinusal and colonic mucosa might suggest a histogenetic hypothesis alternative to those of the malformative or metaplastic origin of naso-sinusal

    Depressed skull fractures overlying the major venous sinus are often managed nonoperatively because of the high associated risks of surgery in these locations. In the presence of clinical and radiographic evidence of sinus occlusion, however, surgical therapy may be necessary. The authors present the case of a 9-year-old boy with a depressed skull fracture overlying the posterior third of the superior sagittal sinus. After initial conservative treatment, delayed signs of intracranial hypertension and a symptomatic tonsillar herniation with tonsillar necrosis developed. Possible causes as well as diagnostic and treatment options are reviewed.

    Squamous cell carcinoma is a rare, but well documented complication of chronic osteomyelitis. Squamous cell carcinoma arising in a sinus tract following chronic osteomyelitis of the pelvic bone is a very rare occurrence. The patient presented with multiple draining sinuses and an ulcerative growth at the mouth of one of the sinuses in the peri-anal region. X-ray findings and sinogram showed de- struction of part of pubic bone. Biopsy from the growth confirmed a well differentiated squamous cell carcinoma. Therefore it is imperative that these lesions be biopsied for accurate diagnosis, adequate therapy and follow-up.

    We present an unusual variant of the sinus venosus defect in which an obvious window is formed between a single pulmonary vein and the superior vena cava, the pulmonary vein retaining its connection to the left atrium. Two patients were operated on via right anterior minithoracotomy. A large single right pulmonary vein was found connecting to the left atrium. There was a large side-to-side communication between the superior vena cava and the pulmonary vein resulting in partially anomalous pulmonary venous drainage. A side-biting clamp was applied in the superior vena cava and the pulmonary vein at both sides of the communication, and the vein was divided. The incision in both veins was closed with a running suture.

    A ruptured sinus of Valsalva aneurysm (RSVA) is a rare cardiac anomaly. Traditionally, RSVAs were repaired surgically; however, percutaneous transcatheter closure is the current treatment of choice. We report two cases of RSVA which were closed using this approach. The first case was a 45-year-old female who presented to the Royal Hospital, Muscat, Oman, in 2014 with a RSVA in the right ventricle. The second case was a 39-year-old male who was admitted to the Sultan Qaboos University Hospital, Muscat, in 2015 with a large multifenestrated RSVA extending into the right ventricle outflow tract. Each patient underwent transcutaneous cardiac catheterisation using three-dimensional echocardiography. Both interventions were technically successful; however, the second patient required a subsequent surgery due to the continuing presence of a significant shunt. Transcatheter closure of RSVAs is an effective alternative to surgical repair, although large multifenestrated RSVAs should be repaired surgically to ensure complete closure. PMID:28003903

    A 1-year-old sexually intact male Korat cat was referred for ophthalmological consultation due to anisocoria. Mydriasis with external ophthalmoplegia and absence of pupillary light responses in the right eye and nasofacial hypalgesia were seen. Cavernous sinus syndrome (CSS) was suspected. Bilateral deformities of the jaw and phalangeal bones, severe spinal pain and abnormal conformation of the lumbar spine were also present. Radiographic examination revealed several mineralised masses in the appendicular and axial skeleton, indicative of multiple cartilaginous exostoses. For further investigation of the CSS-related neurological deficits, the cat underwent computed tomography (CT) examination of the skull. CT images revealed a non-vascularised, calcified, amorphous mass originating from the right lateral skull base and superimposing on the sella turcica. Based on the severity of diffuse lesions and owing to the clinical signs of extreme pain, the cat was euthanased. A diffuse skeletal and intracranial osteochondromatosis was diagnosed histologically.

    The surgical treatment of frontal sinus fractures is foreshadowed by fears of late complications. Complications such as meningitis and mucoceles should be prevented by cranialization or obliteration of the frontal sinus. These procedures are still standard treatment despite of recent developments over the last two decades in endoscopic sinus surgery, in medical imaging and surgical instrumentation. Nowadays the role of cranialization and obliteration is challenged by refined endoscopic frontal sinus surgery techniques, the widely-used image-guided systems and the multiplanar high-resolution computed tomography along with new data about postoperative complications. This overview summarizes the current literature, taking into account the existing evidence in the treatment of frontal sinus fractures.

    Documentation of the psittacine paranasal sinuses has been limited. To provide more published detail, spiral computed tomography (CT) was used to scan the cephalic and cervical region from cadavers of 10 psittacine birds (Ara ararauna, Ara chloroptera, Ara macao, and Anodorhynchus hyacinthinus). Skeletal studies, histologic examinations, and evaluation of deep-frozen sections and anatomic preparations confirmed the results of the CT scans. New morphologic details of the paranasal sinus and some compartments were discovered. The paranasal sinuses of these macaws consist of two unpaired rostral compartments, followed caudally by eight paired compartments. Histologic examinations revealed that the walls of the paranasal sinuses consist of flat or cubic monolayer epithelium with underlying connective tissue. The described method of CT examination of these macaws, especially the positioning, scan orientation and parameters, and documentation of the normal paranasal sinus, provides a basis for future clinical use of CT.

Study Design: A meta-analytic study reviewing articles on sinus augmentation published during the last ten years. Results: 3,975 implants placed in sinus augmentations (with bony windows) were registered, of which 3,749 implants survived, a survival rate of 94.3%. Conclusions: When performing sinus augmentation, bone substitute materials are just as effective as autologous bone, whether used alone or in combination with autologous bone. Implant surface treatments can have an important effect on implant survival and it would appear that roughened surfaces are the best option. When implants are inserted simultaneously to grafting, a higher failure rate can be expected. Key words: Sinus augmentation, bone implant, bone regeneration, dental implant. PMID:22157658

    Carotid cavernous sinus fistulas are abnormal communications between the carotid system and the cavernous sinus. Several classification schemes have described carotid cavernous sinus fistulas according to etiology, hemodynamic features, or the angiographic arterial architecture. Increased pressure within the cavernous sinus appears to be the main factor in pathophysiology. The clinical features are related to size, exact location, and duration of the fistula, adequacy and route of venous drainage and the presence of arterial/venous collaterals. Noninvasive imaging (computed tomography, magnetic resonance, computed tomography angiography, magnetic resonance angiography, Doppler) is often used in the initial work-up of a possible carotid cavernous sinus fistulas. Cerebral angiography is the gold standard for the definitive diagnosis, classification, and planning of treatment for these lesions. The endovascular approach has evolved as the mainstay therapy for definitive treatment in situations including clinical emergencies. Conservative treatment, surgery and radiosurgery constitute other management options for these lesions. PMID:23671750

    Key points Cardiac vagal tone is a strong predictor of health, although its central origins are unknown.Respiratory‐linked fluctuations in cardiac vagal tone give rise to respiratory sinus arryhthmia (RSA), with maximum tone in the post‐inspiratory phase of respiration.In the present study, we investigated whether respiratory modulation of cardiac vagal tone is intrinsically linked to post‐inspiratory respiratory control using the unanaesthetized working heart‐brainstem preparation of the rat.Abolition of post‐inspiration, achieved by inhibition of the pontine Kolliker‐Fuse nucleus, removed post‐inspiratory peaks in efferent cardiac vagal activity and suppressed RSA, whereas substantial cardiac vagal tone persisted. After transection of the caudal pons, part of the remaining tone was removed by inhibition of nucleus of the solitary tract.We conclude that cardiac vagal tone depends upon at least 3 sites of the pontomedullary brainstem and that a significant proportion arises independently of RSA. Abstract Cardiac vagal tone is a strong predictor of health, although its central origins are unknown. The rat working heart‐brainstem preparation shows strong cardiac vagal tone and pronounced respiratory sinus arrhythmia. In this preparation, recordings from the cut left cardiac vagal branch showed efferent activity that peaked in post‐inspiration, ∼0.5 s before the cyclic minimum in heart rate (HR). We hypothesized that respiratory modulation of cardiac vagal tone and HR is intrinsically linked to the generation of post‐inspiration. Neurons in the pontine Kölliker‐Fuse nucleus (KF) were inhibited with bilateral microinjections of isoguvacine (50–70 nl, 10 mm) to remove the post‐inspiratory phase of respiration. This also abolished the post‐inspiratory peak of cardiac vagal discharge (and cyclical HR modulation), although a substantial level of activity remained.

    Unilateral sinus disease (USD) can sometimes be difficult to accurately diagnose before surgery. The application of nasal nitric oxide (nNO) for USD diagnosis and its surgical outcome in USD has not been reported in the literature. We prospectively enrolled sixty-six USD patients who underwent endoscopic sinus surgery for fungal rhinosinusitis (n = 19), chronic rhinosinusitis (CRS) without nasal polyps (n = 13), CRS with nasal polyps (n = 12) and sinonasal mass lesions (n = 22). nNO levels were measured preoperatively and at three and six months postoperatively. Correlations between nNO levels and potential clinical parameters, type of disease, disease severity, and disease-related quality of life (QOL) were assessed. Unlike bilateral CRS, in USD, nNO levels did not correlate with disease severity or postoperative QOL improvements. Except for fungus group, there were no differences in nNO levels between lesion and non-lesion sides in all the other groups. nNO levels on both sides were significantly elevated six months postoperatively in all groups. Fungal rhinosinusitis patients had the lowest preoperative nNO levels, and a cutoff of 239.3 ppb had the best sensitivity (79.0%) and specificity (87.2%) for preoperative diagnosis. While preoperative nNO levels cannot serve as an alternative marker for disease severity of USD, they were lower in fungal rhinosinusitis patients than in other USD patients and may be useful for more accurate diagnosis prior to surgery.

    Allergic fungal sinusitis (AFS) is a condition that has an allergic basis caused by exposure to fungi in the sinonasal tract leading to chronic inflammation. Despite standard treatment modalities, which typically include surgery and medical management of allergies, patients still have a high rate of recurrence. Subcutaneous immunotherapy (SCIT) has been used as adjuvant treatment for AFS. Evidence exists to support the use of sublingual immunotherapy (SLIT) as a safe and efficacious method of treating allergies, but no studies have assessed the utility of SLIT in the management of allergic fungal sinusitis. A record review of cases of AFS that are currently or previously treated with sublingual immunotherapy from 2007 to 2011 was performed. Parameters of interest included serum IgE levels, changes in symptoms, Lund-McKay scores, decreased sensitization to fungal allergens associated with AFS, and serum IgE levels. Ten patients with diagnosed AFS were treated with SLIT. No adverse effects related to the use of SLIT therapy were identified. Decreases in subjective complaints, exam findings, Lund-McKay scores, and serum IgE levels were observed. Thus, sublingual immunotherapy appears to be a safe adjunct to the management of AFS that may improve patient outcomes.

    Sinus node dysfunction (SND) is correlated to the pacemaker sinoatrial node (SAN) cell apoptosis. This study explores the effect of such a dysfunctional SAN on electrical propagation into neighboring atrial tissue. The Fenton Karma model was extended to simulate mouse SAN and atrial cell action potentials. The cell models were incorporated into a 2D model consisting of a central SAN region surrounded by atrial tissue. The intercellular gap junctional coupling, as quantified by the diffusion constant, was estimated to give conduction speeds as observed in mouse atrial tissue. The size of mouse SAN pacemaking region was estimated using the 2D model. In multiple simulations, the effects of an increasing proportion of apoptotic pacemaker cells on atrial tissue pacing were simulated and quantified. The SAN size that gave a basal mouse atrial cycle length (ACL) of 295 ms was found to be 0.6 mm in radius. At low pacemaker cell apoptosis proportion, there was a drastic increase of ACL. At modest increase in the number of apoptotic cells, bradycardia was observed. The incidence of sinus arrest was also found to be high. When the number of apoptotic cells were 10% of the total number of pacemaking cells, all pacemaking was arrested. Phenomenological models have been developed to study mouse atrial electrophysiology and confirm experimental findings. The results show the significance of cell apoptosis as a major mechanism of SND.

    The nasal cavity and parasinusal cancer are rare (10% of tumors of the head and neck) and are mainly represented by squamous cell carcinoma of the nasal cavity or the maxillary sinus and adenocarcinoma of the ethmoid sinus (occupational disease, wood dust). The most common clinical sign is nasal obstruction, but tumors can also manifest as rhinorrhea and/or epistaxis (usually unilateral signs). A magnetic resonance imaging of the facial structure is systematic for staging before treatment. The treatment consists of a first surgery if the patient is operable with a resectable tumor. If it is not the case, the treatment consists of radiotherapy (RT) associated with chemotherapy (CT) according to the initial data (T3/T4 or N+). After first surgery, RT is indicated (except T1N0 with complete resection) associated with a CT based on postoperative data (capsular effraction or incomplete resection). Lymph node irradiation is considered case by case, but is indicated in any nodal involvement. RT must be an intensity modulated RT (IMRT), static or dynamic, and must be imagery guided (IGRT). According to ICRU 83, doses to organs at risk and target volumes must be carried. Finally, after a post-treatment baseline imaging between 2 and 4 months, monitoring will be alternated with the ENT surgeon every 2 or 3 months for 2 years, then every 4 to 6 months for 5 years.

    The range of bone regeneration materials suitable for maxillar bone augmentation has increased steadily in the past few years and there is now a wide variety of materials being used. In the present case report, we analyzed the state of bone regeneration after sinus floor augmentation using a nanocrystalline in-phase synthetic anorganic hydroxyapatite bone grafting material (Ostim). A 60-year-old female patient underwent maxillary sinus floor elevation and the cavity was filled with Ostim three years before. Actually, she presented herself with loosening of the dental implant at position 17, as a result of parafunction. At the time of the insertion of a second implant at position 17, bone samples were taken by using a trepan drilling device from the previously augmented area. These samples were analyzed histologically to determine the extent of bone remodeling around the deposits of Ostim. We found that the Ostim deposits were surrounded largely by woven bone and, in parts, by lamellar bone and had facilitated osteoconductive bone regeneration. The adjacent implant, at position 16, which beared a crown exposed to proper biting forces without parafunction, showed proper clinical and radiological characteristics of complete and firm integration into the area which was also filled with Ostim three years ago. We conclude that the use of the nanocrystalline hydroxyapatite Ostim with its stable volume properties appears to be suitable for maxillary sinus floor augmentation. Furthermore, we even found osteoconductive bone regeneration under Ostim near the site of the loosened implant.

  13. Revisiting old vaginal topics: conversion of the Müllerian vagina and origin of the "sinus" vagina.

    PubMed

    2009-01-01

    Vaginal development has been a longstanding controversy, which hampers studies on vaginal diseases as well as cervical and uterine diseases. Most concerns center on: why is the vaginal epithelium different from the uterine epithelium; and where does the vagina originate from? It is commonly held that the rodent vagina has a dual origin: the cranial part is derived from the Mullerian duct (Mullerian vagina) and the caudal part derived from the urogenital sinus (sinus vagina). This concept was deduced from morphological observations. However, it cannot explain the difference between the Mullerian vagina and the uterus. Moreover, accumulating new data from genetic and molecular studies contradicts the urogenital sinus origin of the sinus vagina. The present review summarizes previous morphological observations and new findings from genetic and molecular studies, and addresses molecular mechanisms underlying the origin and organogenesis of the vagina in rodents. It provides evidence to show that the whole vagina is derived the Mullerian duct. BMP4 reshapes the intermediate mesoderm-derived Mullerian duct into the vaginal primordium. The latter thus exhibits different features from the uterus, including the stratified squamous epithelium and insensitivity to anti-Mullerian hormone. The sinus vagina is formed by extrinsic BMP4-mediated caudal extension of the Mullerian duct. The present review thus shows how a century of controversy over the origin and organogenesis of the vagina has been resolved. This new understanding will provide additional insight into genetic diseases and tumors of the female reproductive tract.

    Objective: Immunoglobulin G4 (IgG4) related sclerosing disease (RSD) of the paranasal sinuses is a rare lesion of dense lymphoplasmacytic tissue, with a high proportion of IgG4+ plasma cells. We presented a rare case of IgG4-RSD with isolated involvement of the paranasal sinuses in the absence of multiorgan involvement. Methods: A case report and comprehensive literature review. Results: To our knowledge, only 11 cases of IgG4-RSD with paranasal sinus involvement have been reported. Patients with IgG4-RSD commonly present with epistaxis and symptoms that mimic chronic rhinosinusitis, e.g., rhinorrhea, nasal obstruction, and facial pressure. On imaging, an expansive and erosive process is described. Surgery provides tissue for immunohistologic evaluation; however, there is a paucity of evidence about the direct extent of surgical resection or medical therapies. Postoperative steroids were typically started, although the regimen was not standardized. Conclusion: Few cases of paranasal sinus IgG4-RSD have been reported in the literature. Evidence-based recommendations regarding treatment and surveillance of paranasal sinus IgG4-RSD are lacking; however, most reports describe systemic steroids as the mainstay of treatment. This single subject analysis, with a review of previously reported cases adds to the expanding body of data related to this rare disorder. PMID:27658185

    The most commonly described indications for surgical management of closed depressed skull fractures are hematoma evacuation and repair of extensive cosmetic deformity. Venous sinus injury, which occurs in a subset of depressed skull fractures is not typically listed as an indication for surgical treatment due to the potential for major venous hemorrhage associated with operation near these structures. However, if patients exhibit signs and symptoms of intracranial hypertension and radiographic findings demonstrate sinus compromise, surgical elevation of the depressed skull fragments is indicated. The authors present the case of a 25-year-old woman with a depressed skull fracture secondary to a gunshot wound with symptomatic compromise in venous outflow of the posterior one-third of the superior sagittal sinus. The patient was treated with surgical decompression via bilateral craniectomy along with intracranial pressure lowering medical therapy and had almost full resolution of her presenting symptoms with documented improvement in flow through the superior sagittal sinus. While the use of surgical treatment for these types of injuries is highly debated we demonstrate here that safe, effective surgical management of these patients is possible and that surgical decompression should always be considered in the case of symptomatic venous sinus flow obstruction.

    Background Paranasal sinus CT has high sensitivity and specificity for sinusitis. However, this modality is costly and involves greater radiation exposure than plain radiographs. Objectives We tried to compare 10-cut limited CT scan and standard CT scan in the diagnosis of sinusitis. Materials and Methods We conducted a cross sectional case series from August to December 2010 on 150 patients with non-randomized sampling method in academic hospitals related to medical school of Shahid Beheshti University of medical sciences. Using standard CT scan as the gold standard, the sensitivity and specificity of limited series were calculated for each sinus group. Results In our study limited CT scan had a sensitivity of 92%, specificity of 94%, positive predictive value of 90% and negative predictive value of 95%. Conclusions The limited CT scan is useful for confirming the clinical diagnosis of sinusitis. PMID:23396584

  19. [Origin of the common pulmonary vein, septation of the primary sinus venosus atrial situs and theory of the "sinus man"].

    Situated at the entry to the heart, the sinus venosus regulates at an early stage the distribution of the veins. Originally symmetrical, it receives on either side an omphalomesenteric vein, a common cardinal vein (duct of Cuvieri, ductus cuvieri) and a common pulmonary vein. This symmetrical pattern disappears with the obliteration of the rough right pulmonary vein and the invagination of the left ductus cuvieri into the sinusal cavity. Thus, the pulmonary venous blood is kept on the left side and the systemic venous blood is transferred to the right side. This is the usual situs solitus arrangement. Situs inversus is the opposite arrangement. In situs ambiguus the original symmetry is preserved. A sufficiently early cauterization of the left wall of the sinus venosus prevents the left ductus cuvieri from invaginating and results in "absence of coronary sinus"; this arrangement, where part of the original symmetry is preserved, is in fact similar to situs ambiguus. The situs of the liver and stomach is thought not to be determined by these organs but imposed to them by the sinus venosus, more precisely by the invagination--or lack of invagination--of a ductus cuvieri. This would explain the concordance between their situs and that of the sinus venosus and atria. It would appear that two errors are frequently made: the common pulmonary vein is said to originate from the left atrium, whereas it originates from the sinus venosus and only belongs to the left atrium when the sinus is incorporated in the atrium; the transverse septation of the sinus is incorporated to a shift to the right of the left sinoatrial fold which separates the sinus from the primitive atrium. This fold is indeed displaced to the right, but it is more distal and corresponds, in fact, to the cephalic border of the left ductus cuvieri, and its shift is produced by the invagination of that duct.

    Segmentation of medical image data is getting more and more important over the last years. The results are used for diagnosis, surgical planning or workspace definition of robot-assisted systems. The purpose of this paper is to find out whether manual or semi-automatic segmentation is adequate for ENT surgical workflow or whether fully automatic segmentation of paranasal sinuses and nasal cavity is needed. We present a comparison of manual and semi-automatic segmentation of paranasal sinuses and the nasal cavity. Manual segmentation is performed by custom software whereas semi-automatic segmentation is realized by a commercial product (Amira). For this study we used a CT dataset of the paranasal sinuses which consists of 98 transversal slices, each 1.0 mm thick, with a resolution of 512 x 512 pixels. For the analysis of both segmentation procedures we used volume, extension (width, length and height), segmentation time and 3D-reconstruction. The segmentation time was reduced from 960 minutes with manual to 215 minutes with semi-automatic segmentation. We found highest variances segmenting nasal cavity. For the paranasal sinuses manual and semi-automatic volume differences are not significant. Dependent on the segmentation accuracy both approaches deliver useful results and could be used for e.g. robot-assisted systems. Nevertheless both procedures are not useful for everyday surgical workflow, because they take too much time. Fully automatic and reproducible segmentation algorithms are needed for segmentation of paranasal sinuses and nasal cavity.

    Background. Thyroidectomy is one of the most frequently performed surgical procedures worldwide. Despite technical advances and high experience of thyroidectomy of specialized centers, it is still burdened by a significant rate of postoperative complications. Among them, the skin sinus formation is an extremely rare postthyroidectomy complication. Here, we first report the incidence of the skin sinus formation after thyroidectomy to identify the causes for skin sinus formation after thyroidectomy and to discuss its prevention and treatment options. Methods. A retrospective analysis was carried out of patients who underwent excision operation of fistula for postthyroidectomy skin sinus formation. Data were retrieved from medical records department of the Affiliated Hospital of Inner Mongolia Medical University. Results. Of the 5,686 patients who underwent thyroid surgery, only 5 patients (0.088%) had developed skin sinus formation. All 5 patients successfully underwent complete excision of fistula. Conclusion. Infection, foreign body, thyroid surgery procedure, combined disease, and iatrogenic factors may be related with skin sinus formation after thyroidectomy. To reduce the recurrence of postoperative infections and sinus formation, intra- and postoperative compliance with aseptic processing, intraoperative use absorbable surgical suture/ligature, repeated irrigation and drainage, and postoperative administration of anti-inflammatory treatment are to be followed.

    Sinusitis is a common disorder in horses and may result from trauma, dental diseases, or space-occupying lesions. Radiography can only provide a limited amount of information. Computed tomography (CT) has been documented as an alternative imaging method. Eighteen horses (mostly Warmblood) with signs of chronic sinusitis were examined preoperatively with CT to assist in diagnosis of the underlying cause. There was a group of common CT features in horses with dental disease and sinusitis. The first molar was the most frequently affected maxillary cheek tooth. Hypoattenuation of the cementum, destruction of the enamel, and filling of the infundibular cavity with gas were the most frequent CT findings associated with caries. Gas bubbles within the bulging root area or fragmentation of the root in combination with swelling of the adjacent sinus lining were the most important CT features of dental decay. CT findings associated with sinusitis included excessive thickening of the respiratory epithelium in the rostral maxillary sinus; the caudal maxillary sinus was less often involved. The infraorbital canal, the nasomaxillary duct, and the frontomaxillary aperture were usually involved. The maxillary bone, however, especially the facial crest, was involved in nearly every horse, being characterized by endosteal sclerosis, thickening, periosteal reaction, and deformation leading to facial swelling in chronic infections. CT images allowed identification of involvement of individual teeth more clearly to reveal the diseased one for treatment. Three-dimensional imaging allowed improved understanding of the extent and severity of the pathologic change.

    Efficient management of chronic sinusitis remains a great challenge for primary care physicians. Unlike ENT specialists using Computed Tomography scans, they lack an affordable and safe method to accurately screen and monitor sinus diseases in primary care settings. Lack of evidence-based sinusitis management leads to frequent under-treatments and unnecessary over-treatments (i.e. antibiotics). Previously, we reported low-cost optical imaging designs for oral illumination and facial optical imaging setup. It exploits the sensitivity of NIR transmission intensity and their unique patterns to the sinus structures and presence of fluid/mucous-buildup within the sinus cavities. Using the improved NIR system, we have obtained NIR sinus images of 45 subjects with varying degrees of sinusitis symptoms. We made diagnoses of these patients based on two types of evidence: symptoms alone or NIR images along. These diagnostic results were then compared to the gold standard diagnosis using computed tomography through sensitivity and specificity analysis. Our results indicate that diagnosis of mere presence of sinusitis that is, distinguishing between healthy individuals vs. diseased individuals did not improve much when using NIR imaging compared to the diagnosis based on symptoms alone (69% in sensitivity, 75% specificity). However, use of NIR imaging improved the differential diagnosis between mild and severe diseases significantly as the sensitivity improved from 75% for using diagnosis based on symptoms alone up to 95% for using diagnosis based on NIR images. Reported results demonstrate great promise for using NIR imaging system for management of chronic sinusitis patients in primary care settings without resorting to CT.

  4. Aneurysm of the sinus of valsalva.

    2006-01-01

    Aneurysms of the sinus of Valsalva (ASVs) are rare. They can be congenital or acquired through infection, trauma, or degenerative diseases. They frequently co-occur with ventricular septal defects, aortic valve dysfunction, or other cardiac abnormalities. Although unruptured ASVs are usually asymptomatic, ruptured ASVs often cause symptoms similar to those of heart failure and produce a continuous, mechanical-sounding murmur. Transsternal or transesophageal echocardiography is usually effective in detecting ASVs. Because symptomatic ASVs pose significant risks for the patient, and because the repair of asymptomatic ASVs generally produces excellent outcomes, surgery is indicated in most cases. The primary goals of surgical repair are to close the ASV securely, remove or obliterate the aneurysmal sac, and repair any associated defects. Operative mortality is generally low except in patients with concomitant bacterial endocarditis or other infections. Late events are uncommon and tend to be related to aortic valve prothesis or Marfan syndrome.

    Anemometry with the hot wire and hot film technique previously described, enables the rhinologist to record slow and rapidly changing air flow in the maxillary sinus. The advantages and disadvantages of this method are considered. Anemometry together with manometry may be designated sinumetry and used as a diagnostic procedure following sinuscopy in chronic maxillary sinus disease. The value of the function from velocity of time allows the estimation of flow-volume in the sinus. Furthermore, the method is useful to evaluate the optimal therapy to restore ventilation in the case of an obstructed ostium demonstrated before and after surgical opening in the inferior meatus.

    The effects of amiodarone on the sinuatrial node were studied in 24 patients after an intravenous injection of the drug (5 mg/kg). Sinuatrial function was assessed by rapid atrial pacing and premature atrial stimulation. Sinus cycle length did not change significantly, but the corrected sinus node recovery time was prolonged. While there was no significant change in sinuatrial conduction time, prolongation of the non-reset zone in 14 cases, as well as the abolition of the platesu in 2/24 patients, suggested that conduction of the atrial responses to the sinus node might have been depressed.

    The main purpose of this pictorial review is to highlight the important MR imaging findings of various conditions involving the cavernous sinus in addition to brief description of normal anatomy. The pathological conditions that can involve the cavernous sinus can be categorized into infective, inflammatory, granulomatous, vascular and neoplastic causes. Imaging, especially with MRI, plays an important role not only in detection but also in definition of disease extent and in characterization of the pathology. Currently, high-resolution MR images clearly show various components of cavernous sinus which help in making a proper diagnosis and thus appropriate further management.

    The objective of this study is to report a clinical case of maxillary sinus with lyophilized, xenogeneic graft, in which, despite a large perforation of the sinus membrane, the surgery was not aborted and the results of histological examinations indicate bone neoformation in the surgical area. Results. This case showed that the biomaterials evaluated in this study and the procedure used to place them proved to be biocompatible and presented high osteogenic potential, leading to a successful surgery and osseointegration implant. Conclusion. Positioning Schneider's membrane and filling it with the graft biomaterial helped to achieve the desired osteoconduction and proliferation of bone cells even though the patient had a large perforation of the sinus membrane.

    Purpose Sinus elevation procedures have become a routine and reliable way to gain bone volume in the edentulous maxilla for dental implant placement. Presence of bony septations and pathology in the maxillary sinus often cause complications leading to graft or implant failure or both. The aim of this study was to retrospectively evaluate the prevalence of pathology, direction of the septa, and sinus width measured at 2 mm, 5 mm, and 10 mm from the sinus floor in maxillary sinuses using cone-beam computed tomography (CBCT). Materials and Methods Seventy-two sinuses from 36 random preoperative CBCT scans referred for implant therapy were retrospectively evaluated for the number, prevalence, and direction of bony septations and presence of pathology. Width of the sinus was also measured at 2 mm, 5 mm, and 10 mm from the sinus floor to account for the amount of bone available for implant placement. Results Maxillary sinus septa were found in 59.7%. Presence of a single septum was noted in 20 sinuses (27.7%), followed by two septa in 17 sinuses. The most common direction of the septum was the transverse direction. Retention pseudocyst and mucosal thickening were the most commonly seen abnormality/pathology. Conclusion Based on the high prevalence of septa and sinus pathology in this sample, a preoperative CBCT scan might be helpful in minimizing complications during sinus augmentation procedures for dental implant therapy.

    The most frequent primary infections causing purulent meningitis in older children are both acute and chronic otitis media and sinusitis or upper and lower airways infections. In these cases sometimes purulent meningitis is accompanied with other intracranial complications. Pharmacological treatment of intracranial complications without surgical intervention concerning primary source of infection increases risk of complications including death of a patient and also recurrences of bacterial meningitis. In the paper authors present two uncommon cases of children with purulent meningitis and other intracranial complications of otitis media and sinusitis diagnosed by pediatricians.

    Abstract Sinus histiocytosis with massive lymphadenopathy (SHML), also called Rosai-Dorfman disease, is a rare entity. Its etiology and pathogenesis are still essentially unclear. The histologic hallmark of this disease is proliferation of distinctive histiocytes within lymph node sinuses and in extranodal sites. Approximately 23% of patients with SHML, documented in the SHML Registry, presented with disease primarily in extranodal sites, and very few cases of SHML (<1%) involving the gastrointestinal system have been described in the literature. We report an unusual case of primary pancreatic SHML with infiltration of the process into peripancreatic, perinephric, and perisplenic adipose tissue, simulating malignancy.

    The Vent-Os Sinus Dilation System is an osmotically driven device that provides a means to access the sinus space and to dilate the maxillary sinus ostia and associated spaces in adults for diagnostic and therapeutic procedures. Unlike balloon dilation devices that use rapid, high-pressure inflation, this self-expanding device is designed to gently and gradually open the maxillary ostia. The procedure can be safely and easily completed in-office with minimal anesthetics and analgesics on board. Clinical results support excellent patency and safety outcomes with the use of this product in patients with chronic rhinosinusitis.

    Introduction Personal identification and gender determination of unknown person has a vital importance in forensic investigation. Human skull radiography is a useful tool in human identification in natural disaster, in any accidents such as fire accident and road traffic accident where body remains become degraded or severely destroyed. Aim Present study was performed to evaluate the measurement of frontal sinus, uniqueness of various pattern of nasal septum when combined with frontal sinus observed on posterio anterior cephalogram for sex determination as well as personal identification. Materials and Methods A total of 80 individuals, 40 males and 40 females, between the age ranges of 18-30 years were selected. The selected individuals had their Posterio Anterior (PA) cephalogram performed after taking their informed consent. Right and left areas and the maximum height and width of the frontal sinus were determined and septum patterns were evaluated and both patterns were also combined and compared. The radiographs were taken on Xtropan 2000 OPG X-ray machine with cephalography attachment and KODAK CR 7400 digital radiography system. Mean and SD values of the greatest height and width of frontal sinus in male and female patients were thus evaluated. The mean values of the frontal sinus were greater in males and the left area was larger than the right area, based on student’s t-test at the 5% level of significance. Results The combination of Frontal Sinus Patterns and Nasal Septum Patterns (FP+NSP) were assessed and found that there were nine classifiable patterns in 26 (32.5%) individuals (12 males and 14 females), each of which had common representations in more than one individual. Besides these patterns, there were unique unclassifiable patterns in 54 (67.5%) individuals. Conclusion The present study supports the use of radiographic evaluation of frontal sinus dimensions, frontal sinus patterns, nasal septum deviations and the combination FP+NSP patterns for

    The aim of this study was to determine the frequency of misdiagnosis of sinus headache in migraine and other primary headache types in the children and adolescents with chronic or recurrent headaches. Children with chronic or recurrent headaches (n = 310) were prospectively evaluated. Data collection for each patient included history of previously diagnosed sinusitis due to headache, and additional sinusitis complaints (such as fever, cough, nasal discharge, postnasal discharge) at the time of sinusitis diagnosis, and improvement of the headache following treatment of sinusitis. If sinus radiographs existed they were recorded. The study included 214 patients with complete data. One hundred and sixteen (54.2%) patients have been diagnosed as sinusitis previously and 25% of them had at least one additional complaint, while 75% of them had none. Sinusitis treatment had no effect on the headaches in 60.3% of the patients. Sinus graphy had been performed in 52.8%, and 50.4% of them were normal. The prevalence of sinus headache concomitant with primary headache, and only sinus headache was detected in 7 and 1%, respectively, in our study. Approximately 40% of the patients with migraine and 60% of the patients with tension-type headache had been misdiagnosed as "sinus headache". Children with chronic or recurrent headaches are frequently misdiagnosed as sinus headache and receive unnecessary sinusitis treatment and sinus graphy.

    Carcinoid tumors are rare, indolent, neuroendocrine tumors that are most commonly found in the gastrointestinal tract and lungs. They occasionally develop in the head and neck, either as a primary tumor or, more commonly, as a metastasis. The most common sites of head and neck carcinoids are the larynx and middle ear. Only a few cases of carcinoid in the nasal cavity and paranasal sinuses have been reported. We describe a case of primary typical carcinoid of the frontal sinus in a 61-year-old man, and we review the clinical, imaging, surgical, and histochemical findings in this case. The patient was treated with endoscopic resection. A subsequent workup for metastatic and occult primary disease was negative, confirming that the frontal sinus was the primary source. At follow-up 12 months postoperatively, the patient remained without disease. To the best of our knowledge, this is the first report of a primary typical carcinoid tumor originating in the frontal sinus.

    Objective. The aim of our study was to try to determine the possible environmental risk factors for noninvasive fungal sinusitis in Egyptian patients. Methods. This is a prospective epidemiological case control study on the environmental risk factors of noninvasive fungal sinusitis. It included 60 patients and 100 age and sex matched controls. Results. There was a statistically significant relation between apartment floor, surface area, exposure to dust, exposure to cockroaches, poor air conditioning, and fungal sinusitis. Yet, no statistical significance was found between allergy related occupations, exposure to animals or plants, although their percentages were higher among cases, smoking, and urban or rural residence. Conclusion. We suggest that for patients with noninvasive fungal sinusitis a change in their living environment must be implied with better exposure to sunlight, larger well ventilated homes, proper cleaning of dust and cockroach extermination, and if possible the judicious use of air conditioners.

    Cavernous sinus syndrome is characterised by internal and external ophthalmoplegia and sensory deficits over the head due to combined deficits of the three cranial nerves (CNs) responsible for the eye movements and pupil function (CN III, IV, VI) and at least one branch of the trigeminal nerve (CN V). It has rarely been described in cats and may occur secondarily to inflammatory, infectious or neoplastic lesions within the region of the cavernous sinus on the ventral aspect of the calvarium. This report describes the clinical and magnetic resonance imaging findings in a 14-year-old domestic shorthair cat with neurological deficits compatible with cavernous sinus syndrome caused by presumptive extranodal lymphoma. Treatment with chemotherapy resulted in clinical and imaging remission. Identification of the neurological deficits in cavernous sinus syndrome allows accurate neuroanatomical localisation in order to target diagnostic imaging studies.

    In a prospective study, patients with the diagnosis of chronic ethmoid sinusitis were evaluated microbiologically by using biopsy specimens of the ethmoid sinus mucosa. Microbiology cultures were performed on 94 specimens from 59 patients. Staphylococcus aureus and members of the family Enterobacteriaceae were the most frequent classical pathogenic bacteria isolated. Coagulase-negative staphylococci were the most common overall isolates. Streptococcus pneumoniae and Haemophilus influenzae were infrequent isolates. No anaerobes, viruses, or Chlamydia trachomatis organisms were identified. Results of this study showed organism isolation frequencies different from those found in other studies of chronic sinusitis reported in the literature. The predominance of S. aureus and members of the family Enterobacteriaceae could have an effect on the antimicrobial therapy for chronic ethmoid sinusitis. PMID:1774242

    By means of corrosive, injection and tracheoscopy methods venous formations of the brain have been studied in 19 species of birds--endemical for Far East--from 12 orders. Four types of the venous sinuses structure have been distinguished in the dura mater: the first type of the structure is specific for birds that live an inactive and quiet life (blue rock pigeon, Ussuric pheasant, Tetrastes bonasia, domestic hen). The second type of the sinus structure occurs in birds, that sharply change the speed and height of their flight (Otus bakkamoena). The most manifested changes in the sinus structure are noted in waterfowl and diving birds, that spend much time in flight, in dendrocolaptidae and in day predaceous birds; in them the longitudinal sinus forms a rhombus.

    The maxillary sinus, or Highmore's antrum, is located in the maxillary bone. The maxillary, above the buccal cavity, below the orbital cavity and outside the nasal fossa, is going to take a part in the formation of the three cavities which surround it. Although voluminous, it is consists of a light bone. This distinctive feature is essentially due to the fact that the maxillary has a cavity. The maxillary sinus occupies the upper 2/3s of this maxillary bone. It is the largest of the facial structure's cavities. Its volume is very variable, depending on the individual, the condition of their edentulousness and their age. We find small, average or large sinuses. This sinus communicates with the corresponding nasal fossa by a canal. It opens at the level of the nasofrontalis duct by a meatic ostium, an ostium located at the top of the meatus nasi medius, i.e. under the floor of the sinus. This highly positioned drainage location easily explains the problems that sinus pathologies can come up against. The sinus is lined with a mucous membrane and we can point out that in the normal condition this mucous membrane adheres weakly to the bone. It is more or less thick as a function of the pathologies to which the sinus has been subjected, or even as a function of the geographical location where the individual lives. The imaging of this sinus as a function of age is not obvious due to the fact that it is invisible throughout embryonic and foetal development, and that it only becomes visible to X-rays relatively late, at about 6 years old. Its role is important at the level of the growth of the facial structure because it is always easier to have growth around cavities. It also has a mechanical role concerning the transmission of shockwaves during traumas. In old individuals, due to the condition of the edentulousness, the volume of the sinus is larger; in fact one can note the resorption of the alveolar bone. The maxillary sinus is a cavity which plays a very important role

    The purpose of this article is to present the case of maxillofacial trauma patient with maxillary sinus fracture diagnosed with cone-beam computed tomography (CBCT) and to explore the applications of this technique in evaluating the maxillofacial region. A 23-year-old male patient attempted to our clinic who had an injury at midface with complaints of swelling, numbness. The patient was examined before in emergency center but any diagnosis was made about the maxillofacial trauma. The patient re-examined clinically and radiographically. A fracture on the frontal wall of maxillary sinus is determined with the aid of CBCT. The patient consulted with the department of maxillofacial surgery and it is decided that any surgical treatment was not necessary. The emerging technique CBCT would not be the primary choice of imaging maxillofacial trauma. Nevertheless, when advantages considered this imaging procedure could be the modality of choice according to the case. PMID:25045417

    Introduction: Aneurysmal Bone cysts (ABC) are extremely rare in the head and neck region and even rarer in sinuses. ABC is a benign multicystic mass that is locally-destructive and rapidly expandable. Hemorrhagic fluid content (like in this case) and septated appearance are the characteristic feature of ABC. Established treatment options for ABCs include sclerotherapy, embolization, radiotherapy, simple curettage, surgical excision, or a combination of methods. Case Report: In this article, a 5 year-old boy with a recurrent nasal mass is presented. The patient was finally diagnosed with this rare entity: ABC of the paranasal sinuses. The patient was treated through complete surgical removal. Conclusion: ABC can be considered as a rare differential diagnosis of recurrent nasal hemorrhagic mass in a pediatric population.

    We present the case of a woman on whom a percutaneous endoscopic gastrostomy (PEG) was performed through the sinus tract of a previous surgical gastrostomy for supraglottic obstructing malignancy. Five years after the induction of the surgical gastrostomy, she experienced a peristomal leakage, leading to severe necrotizing fasciitis, with skin irritation and inflammation. Despite extensive treatment to heal the abdominal wall close to the feeding tube, it recurred 3 months later, without any obvious cause. It was thus decided to perform a new gastrostomy in a nearby normal skin area, but, since it was totally impossible for the endoscope to be passed by mouth, due to obstruction, the sinus tract of the gastrostomy was used to facilitate endoscope insertion into the stomach for a new PEG.

    Sinus of Valsalva aneurysm is a rare, catastrophic complication of endocarditis. We report an unusual case of ruptured sinus of Valsalva aneurysm associated with endocarditis that was caused by Streptococcus pneumoniae serotype 21. The patient, a 12-year-old girl, underwent surgical repair of the aneurysm and was given intravenous antibiotics for 6 weeks. She was doing well at the 6-week follow-up visit. This case is unusual because of the patient's young age at presentation, the absence of predisposing factors, and the isolation of a nonvaccine serotype 21, which revealed the epidemiologic changes of invasive pneumococcal disease. To our knowledge, this is the first reported case of endocarditis caused by this S. pneumoniae serotype.

    Traumatic injuries in childhood may disrupt root development leading to a tooth with open apex. Apexification procedures in such cases aim at root end closure after reasonable period of time. In some chronic cases, complete healing of the periapical area does not occur resulting in development of a nonhealing sinus. Failure of nonsurgical approach in such cases needs surgical intervention permitting thorough periapical curettage. In the present case, apexification procedure with MTA achieved root end closure but failed to heal the sinus for which surgical treatment was completed with thorough periapical curettage and application of platelet rich fibrin (PRF) and a combination of β-tricalcium phosphate and hydroxyapatite resulted in healing.

    The purpose of this study was to evaluate dimensions of adult human maxillary sinuses on panoramic radiographs and their possible application on the sex determination for forensic purposes. The sample comprised 64 database panoramic radiographs from individuals aged 20 years or older (32 male and 32 female subjects), with complete permanent dentition (or absence of third molars). One examiner measured the width and height of the right and left maxillary sinuses using the software Image J 1.47v (National Institutes of Health, Bethesda, USA). Measurements were repeated to calculate intra-observer agreement. Chi-Square test, Kappa, ANOVA and T-Student were used for results analysis for p≤ 0.05. Intra-observer agreement with correlation Kappa ranged between 0.38 and 0.96. For female subjects, the mean height and width of the left maxillary sinus were 28.7856mm and 44.6178mm, respectively. And right maxillary sinus was 27.7163mm for height and 45.1850mm for width. Male subjects were found to have the mean height and width of the left maxillary sinus 30.9981mm and 48.7753mm, respectively. And right maxillary sinus was 30.7403mm for height and 48.5753mm for width. There was a statistically significant difference in the height and width of maxillary sinuses between males and females. It can be concluded that maxillary sinuses height and width on panoramic radiographs can be used to determine the gender of adult human subjects.

    A 33-year-old man who had received mediastinal radiation therapy for Hodgkin's disease 12 years earlier developed a symptomatic sick sinus syndrome requiring the implantation of a permanent pacemaker. The sick sinus syndrome and a finding of an occult constrictive pericarditis were considered to be due to the previous mediastinal irradiation. A ventricular pacemaker was chosen because mediastinal radiotherapy also increases the risk of developing atrioventricular conduction defects.

    Late recovery of sinus rhythm is unusual in patients with permanent AF treated by (radiofrequency) RF maze procedure during mitral valve surgery. Identification of clinical and instrumental preoperative factors predictive of early success of RF ablation in patients with permanent AF undergoing mitral valve surgery may improve selection of subjects to obtain long-term results. Hundred and thirty consecutive patients with permanent AF and mitral valve disease underwent modified RF maze procedure during concomitant mitral valve surgery. Rheumatic valve disease (61 pts) and mitral valve prolapse (41 pts) were the more common aetiology of valve abnormalities. Mitral valve replacement was performed in 54 % of patients and mitral valve repair in the remaining 46 %. Four patients died after surgery. At discharge, 87 patients (69 %) were in sinus rhythm (group 1) and 43 patients in AF persisted (group 2). At an average 24-month follow-up, sinus rhythm was present in 67 % of patients, and 33 % were in atrial fibrillation. In this period, late recovery of sinus rhythm was observed only in five patients, while eight discharged in sinus rhythm developed again atrial fibrillation. Among preoperative parameters at univariate analysis female sex, atrial fibrillation >24 months, left atrial diameter >54 mm, left atrial area >24 cm(2), rheumatic valve disease and NYHA class were associated with persistence of AF. At Cox regression multivariate analysis, increased left atrial area (OR 1.07 per unit increase-95 % CI 1.01-1.131) and rheumatic aetiology of valve disease (OR 4.52, 95 % CI 1.65-12.4) were associated with persistence of AF at hospital discharge. Persistence of AF after RF ablation in patients undergoing mitral valve surgery is related to aetiology, e.g. rheumatic valve disease, and to increasing left atrial diameter. Due to low rate of late recovery of sinus rhythm, indication to RF ablation associated with MV surgery should be carefully considered in patients with large
