    The authors present their experience of managing an interesting case of a 65-year-old woman who presented to their clinic with 1-month history of persistent deep-seated headache. The patient sought medical advice in neurology and ophthalmology clinics before being referred to the ear, nose and throat clinic. CT imaging revealed isolated opacification and expansion of both sphenoid sinuses with bony continuity along the periphery of the sinuses features consistent with mucocele. MRI was needed to fully evaluate the extension of the lesion. The lesion was diagnosed as bilateral sphenoid sinuses mucoceles. Transnasal endoscopic drainage of the sphenoid mucoceles leads to gradual improvement of the symptoms. We discuss the clinical presentation, diagnosis and treatment of this case as well as a review of the literature. PMID:23093506

    Isolated sphenoid sinusitis is a rare disorder and may present with complications due to its anatomical location and proximity to the intracranial and orbital contents. It is frequently misdiagnosed, because the sphenoid sinus is not visualised adequately with routine sinus radiographs and is not accessible to direct clinical examination. We report a case who presented with hemicranial headache and ipsilateral abducens nerve palsy as the presenting feature of sphenoid sinusitis. The symptoms disappeared within a week of conservative treatment. Sphenoid sinusitis should be kept in the differential diagnosis of isolated sixth cranial nerve palsy, especially in the presence of headache, and all patients should be investigated with CT/MRI brain. Prompt diagnosis and management before intracranial extension can prevent devastating complications.

    Mucocele is a rare, benign, cystic tumor affecting primarily adults. It arises within the sphenoid sinus and invades the orbit through bony destruction. The most frequent locations are frontal and fronto-ethmoidal; sphenoidal forms are rarer, and bilaterality is exceptionally rare. Ophthalmological signs with the risk of blindness required emergency treatment. The authors report a case of bilateral sphenoid mucocele presenting as an isolated abducens nerve palsy, the etiological investigation confirmed the diagnosis of sphenoid mucocele, and the treatment consisted of a surgical marsupialization through an endonasal endoscopic approach.

    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

    Fibrous dysplasia (FD) of the sphenoidal sinus is a rare disease, especially during adulthood. We report a case of FD of the right sphenoidal sinus in an adult male patient who presented with nonspecific symptoms limited to headache localized to the right temporal area and to the inferior orbital rim of both sides. Magnetic resonance imaging revealed a dense mass that occupied the entire right sphenoidal sinus and skull base with typical ground-glass opacification and bony sclerosis of the whole sphenoidal wall. The diagnosis of FD was confirmed on pathological examination of a biopsy taken through sphenotomy. The patient underwent a subcranial craniotomy for tumor resection. After more than 4 years of follow-up, the patient was disease-free. On the basis of these clinical features, it is important to consider sphenoidal FD in both young and adult patients complaining of an unexplained headache, because it may present unusually with headache localized to the temporal region or the inferior orbital rim.

    A 43-year-old male scuba diver presented with an acute history of painful unilateral visual loss after scuba diving. He had right-sided retrobulbar pain and headache. He was known to have sinusitis and had transient visual loss in two previous episodes after scuba diving. His visual acuity was hand motions and 20/20 in the right and left eye, respectively. There was no proptosis. He had a right relative afferent pupillary defect. Colour vision was normal in the left eye and absent in the right eye. Fundal examination revealed healthy discs and macula bilaterally. He was assessed as a right optic neuropathy, possibly secondary to compression. An MRI of the brain revealed a large sphenoidal mucocele extending into the right optic foramen. He was treated with oral steroids, antibiotics and nasal decongestants. He underwent endoscopic intranasal sphenoidectomy and marsupialisation with return of his visual acuity to 20/25 in that eye.

    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

    Mucoceles involving the sphenoidal sinus are not as common as those affecting the frontal and ethmoidal sinuses. The subtle expansile change produced by a sphenoidal sinus mucocele often requires conventional tomography or computed tomography examination to be detected. Similarly, involvement of surrounding structures by a sphenoidal mucocele may require special study, which this section illustrates. The sphenoidal enlargement and density change produced by fibrous dysplasia may mimic sinus disease. Focal or widespread bone destruction resulting from neoplastic involvement of the sphenoidal sinus requires special examination similar to that used with mucoceles.

    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.

    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.

    The consequences of intracranial spread of sinus infection can be dismal. The subtle presentation of sphenoid sinusitis often leads to a delay in diagnosis. The disease may go unrecognized until complications are severe enough to cause more localizing symptoms. Often infections in the head and neck spread into the cranial cavity, leading to a localized effect. For example, otogenic infections can spread to the mastoid or lateral venous sinus. We report a case of sphenoid sinusitis complicated by lateral and sigmoid venous sinus thrombosis.

    A fistula of the lesser sphenoid wing sinus is a rare dural arteriovenous fistula resulting from a connection between the middle meningeal artery and recipient vein in the sinus of the lesser sphenoid wing. In this report, MRI/magnetic resonance angiography of a 54-year-old man who presented with sudden-onset glaucoma and proptosis revealed a fistula in this anatomic location. Drainage patterns here may account for the absence of serious complications and optimistic prognosis following embolization. Care in diagnosis is required to avoid superfluous procedures, because classic signs of the more common carotid-cavernous fistula are absent. PMID:19966661

    The aim of this study is the evaluation of the anatomical structures of sphenoid sinus ostium used as a reference point for transsphenoidal surgery by cone beam computed tomography. The authors' study was performed using the cone-beam computed tomography images of 16 to 82-year old 200 (112 female, 88 male) patients (Newton 5G, Verona, Italy). Septum deviation of sphenoid sinus and the distance between 2 ostia were evaluated by coronal and axial sections, respectively. Pneumatization degree of sphenoid sinus, diameter of sphenoid sinus ostium, and distance lower edge of superior turbinate to sphenoid sinus ostium were measured by using sagittal sections. The sellar type was the most common pneumatization type of sphenoid sinus in authors' study. While the C-type septum deviation was observed as the most common, T-type deviation was the least type. Sphenoid sinus ostium was bilaterally in 71.5% of individuals, and it was not found in 10% of individuals included in the study. A significant decrease was determined in diameter of the left sphenoid sinus ostium with aging. The distances between 2 sphenoid sinus ostia were 7.30 ± 2.77 mm for women and 6.09 ± 2.58 mm for men, respectively. No statistical differences were found in women and men in terms of distances between the lower edge of the right and left superior turbinate and sphenoid sinus ostium on their sides. Consequently, making detailed preoperative radiological evaluation of anatomic variations of sphenoid sinus and sphenoid sinus ostium is important in terms of guiding the surgeon in the process of a successful transsphenoidal surgery.

    A 37-year-old woman presented with isolated right-sided oculomotor nerve palsy. Neurologic examination revealed no other disorder. Computed tomography of the paranasal sinuses demonstrated complete opacification of the sphenoid sinus. Dense mucoid fluid was drained from the sphenoid sinus via an endoscopic transseptal sphenoidotomy. A biopsy confirmed the diagnosis of sphenoid sinus mucocele. At follow-up 4 weeks postoperatively, the patient's ocular symptoms were markedly alleviated. Considering rare causes of isolated oculomotor nerve palsy, such as sphenoid sinus mucocele, is important in the differential diagnosis, even in patients with well-known risk factors such as diabetes mellitus.

    Paranasal sinus disease can cause a condition that mimics optic neuritis. Simultaneous appearance of both diseases would create etiological dilemma. We report two cases of retrobulbar optic neuropathy secondary to isolated sphenoid sinus disease. In the case of a 65-year-old female who had presented with acute loss of vision in the left eye associated with left-sided frontal headache which subsequently turned out to be caused by optic nerve compression at the orbital apex due to collection in abnormally pneumatized left lesser wing of the sphenoid. In another case, a 65-year-old lady had presented with symptoms of bilateral retrobulbar optic neuropathy which was found to be due to direct compression of optic nerves at the orbital apex secondary to metastases from breast carcinoma.

    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.

    The aim of this study was to investigate the relationship between the morphological characteristics of the sphenoid sinus and endoscopic localization of the cavernous sinus (CS) using an extended endoscopic endonasal transsphenoidal approach. Thirty sides of CS in 15 adult cadaver heads were dissected to simulate the extended endoscopic endonasal transsphenoidal approach, and the morphology of the sphenoid sinus and anatomic structures of CS were observed. The opticocarotid recess (OCR), ophthalmomaxillary recess (V1V2R), and maxillomandibular recess (V2V3R) in the lateral wall of the sphenoid sinus were presented in 16 sides (53.3%), 6 sides (20%), and 4 sides (13.3%) of the 30 sides, respectively. OCR is a constant anatomic landmark in endoscopy and coincides with the anterior portion of the clinoidal triangle. The C-shaped internal carotid artery (ICA) in the lateral wall of the sphenoid sinus was presented in 11 sides (36.7%), the upper one-third of which corresponds to the middle portion of the clinoidal triangle, and the lower two-thirds of which correlates to the supratrochlear triangle, infratrochlear triangle, and ophthalmic nerve in CS, around which the medial, lateral, and anteroinferior interspaces are distributed. From a front-to-behind perspective, the C-shaped ICA consists of inferior horizontal segment, anterior vertical segment, clinoidal segment as well as partial subarachnoid segment of the ICA. OCR and C-shaped ICA in the lateral wall of the sphenoid sinus are the 2 reliable anatomic landmarks in the intraoperative location of the parasellar region of CS.

    Sphenoidal sinus mucoceles are indolent lesions that, when sufficiently large, can compress on the optic canal or superior orbital fissure, rapidly causing loss of vision, optic neuropathy, ptosis, pain, ophthalmoplegia, and diplopia. We herein report a 72-year-old gentleman who presented acutely with Cranial Nerve II, III, and IV palsies secondary to a sphenoidal sinus mucocele that was confirmed on magnetic resonance imaging and successfully treated with endoscopic drainage. This cause of orbital apex syndrome is important for clinicians to know as early diagnosis and treatment is critical in recovering visual potential. PMID:23961035

    This paper is about sinus balloon dilatation in treatment of acute left sphenoid sinusitis with left impaired vision in a child. Balloon catheter dilatation (BCD) of the sinus ostia is a new technique. It has been shown to be a minimally invasive technique to manage chronic sinusitis. However, this method is rarely used in the treatment of acute sinusitis. So far, we know of no reported cases of sinus balloon dilatation in treatment of this case, especially for children.

    2016-01-01

    Primary non-Hodgkin lymphoma (PNHL) of the sphenoid sinus is a rare neoplasm that poses a diagnostic challenge to clinicians. The proximity of the optical nerve and canal to the sphenoid sinus is accountable for the high incidence of visual disturbance in PNHL of the sphenoid sinus. In particular, patients whose radiologic diagnosis reveals bone destruction in the lateral wall involved with optical-nerve-canals or cavernous sinus present a high risk of rapidly developing unilateral blindness. The present study reports 2 rare cases of PNHL of the sphenoid sinus. Sudden sight loss may follow minimally invasive biopsy. In such cases, the measures that must be taken for the prevention of permanent sight loss are limited in the absence of the final pathologic diagnosis. PMID:27313774

    Solitary fibrous tumor (SFT) is an uncommon neoplasm that usually arises from the pleura. To our knowledge, only 30 cases of SFTs in the nasal cavity and paranasal sinuses have been reported in the literature. We describe an SFT that arose from the right sphenoid sinus and extended to the nasal cavity and epipharynx. The tumor was completely removed by endoscopic sinus surgery without complication. The patient is taking an uneventful course without any evidence of recurrence of the disease 8 months after surgery now.

    Summary This study was designed to elucidate the generating mechanism, diagnosis and treatment of traumatic carotid cavernous fistula (tCCF) concomitant with pseudoaneurysm in the sphenoid sinus. Six cases of tCCF concomitant with pseudoaneurysm in the sphenoid sinus were analyzed in this study. Clinical history, neurological examination, CT and MRI scans, pre- and postembolization cerebral angiograms and follow-up data were included. All patients presented with massive epistaxis and symptoms of tCCF. The pseudoaneurysms and fistulas were occluded with detachable balloons, and preservation of the parent artery in two cases. One patient also had indirect carotid cavernous fistula (CCF) on the contralateral side embolized by transfacial vein approach with microcoils. Complete symptom resolution was achieved in all cases, without procedure related complications. During the follow-up period all patients returned to work. Falling from a high speed motorcycle without wearing a helmet may be one of the main causes of this disease. The site of impact during the accident mostly localizes in the frontal and lateral of the orbit. Intracavernous sinus hypertension of tCCF combining with fracture of the lateral wall of the sphenoid may lead to the formation of a pseudoaneurysm in the sphenoid sinus. MRI scan is very helpful in the diagnosis of this disease before the patient receives angiography. Detachable balloon occlusion of the pseudoaneurysm and fistula is a safe and efficient treatment.

    Sternberg's canal is a congenital bony defect in the lateral wall of the sphenoid sinus. If it persists to adulthood, it may become a source of spontaneous cerebrospinal fluid leak (CSF) and meningoencephalocele. The aim of the study was to describe the authors’ experience and review articles related to spontaneous sphenoid sinus CSF leaks and Sternberg's canal. We analysed patients managed surgicallly due to sphenoid sinus CSF leak and performed a PubMed database search. Two female patients with spontaneous CSF leak of sphenoid origin were found. Both patients underwent surgery with the endoscopic endonasal approach, and the defect was closed using the multi-layer technique. Twelve articles related to CSF leaks of sphenoid origin (due to Sternberg's canal) were found in the PubMed database. Lines of lesser resistance within sphenoid bone may underlie CSF leak pathology together with intracranial hypertension. The endoscopic transnasal approach to the sphenoid sinus is an excellent alternative to standard transcranial procedures. PMID:26240642

Both patients underwent surgery with the endoscopic endonasal approach, and the defect was closed using the multi-layer technique. Twelve articles related to CSF leaks of sphenoid origin (due to Sternberg's canal) were found in the PubMed database. Lines of lesser resistance within sphenoid bone may underlie CSF leak pathology together with intracranial hypertension. The endoscopic transnasal approach to the sphenoid sinus is an excellent alternative to standard transcranial procedures.

    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. PMID:25302142

    Paranasal sinus fungus ball is within the non-invasive forms and is characterized by the presence of aggregated hyphae that do not invade the sinus mucosa. Mucoceles are benign, expansile, cyst-like lesions of the paranasal sinuses. The mucoid secretions of mucoceles are usually sterile. However, secondary infections, mostly bacterial, may lead to the development of pyocoeles. Although an association between a fungus ball and a mucocele is rare in the paranasal sinuses, this disease entity should be considered in the differential diagnosis of expansile, cystic sinus lesions. In this article, clinical and radiological findings of a 61-year-old male patient with isolated sphenoid sinus fungus ball within a mucocele presented with headache and periorbital pain were discussed with recent literature.

    A case of painful ophthalmoplegia associated with an extensive lesion involving the sella turcica, superior orbital fissure, and sphenoid sinus in a 57-year-old man is reported. Even though nasal and ocular symptoms and signs represent the usual features of sphenoidal mucoceles, extension to the intracranial cavity as seen in this lesion is rare. Surgical exploration via a sublabial, transseptal approach revealed a mucocele of the sphenoid sinus. This case exhibited extensive and aggressive behavior simulating a malignant neoplasm.

    Background Traumatic carotid-cavernous fistulas (CCFs) present the clinician with diagnostic and surgical challenges. Extension of a CCF into the sphenoid sinus presents additional management difficulties. Endovascular interventions using various thrombogenic materials such as balloons, coils, or liquids are effective treatment strategies. Ideally, these techniques are used to obliterate the fistula while maintaining the patency of the parent artery. Case Report We present a rare case of traumatic carotid-cavernous sphenoid sinus fistulas complicated by multiple tears in the internal carotid artery with direct communication to the cavernous and sphenoid sinus. As a result, the patient developed massive epistaxis requiring emergent endovascular intervention. A total of 87 detachable coils were placed into the cavernous and sphenoid sinuses via transarterial and transvenous routes in a staged procedure, resulting in complete obliteration of the patient's multiple fistulas. Conclusion To our knowledge, this is the first reported case of multiple fistulous tears in the internal carotid artery with extension to the cavernous and sphenoid sinus. This report emphasizes the importance of early diagnosis and neurosurgical intervention. PMID:25829888

    2012-01-01

    Background: Pituitary adenomas are a common cause of endocrinal dysfunction, which comprise 10–20% of all intracranial tumors. Although almost all of them arise within the sella turcica, there are some rare cases in which a pituitary adenoma is located outside the intrasellar region, so it is defined as an ectopic pituitary adenoma (EPA). Case Description: We described a case of a 31-year-old male with a serum prolactin (PRL) value of 240 ng/ml Magnetic resonance imaging (MRI) showed a space-occupying mass within the sphenoid sinus (SS) which partially enhanced by gadolinium. MRI did not reveal any sellar floor defect and an empty sella was detected. As dopamine agonist treatment had failed in lowering the serum PRL level, he underwent surgical treatment. A transsphenoidal approach without opening the sellar floor was performed using an operating microscope and the lesion within the SS was completely removed. Conclusion: Although intrasphenoidal EPAs are rare findings, the presence of an endocrine disorder related to pituitary hormones, and a space-occupying mass within the SS associated with either a normal sellar pituitary gland or an empty sella must lead us to suspect this diagnosis.

    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.

    2014-01-01

    Background Mucocele is an inflammatory disease caused by the retention of mucoid secretions within a paranasal sinus. Although rare, the presence of a vascular lesion inside the sphenoid sinus could determine ostium obstruction, thus causing mucocele development. Clinical Presentation An 84-year-old woman was referred to our institution due to a lesion abutting into the sphenoid sinus; she was complaining of constrictive frontal headache, progressive worsening of visual acuity in the left eye; later, sudden homolateral ptosis and diplopia occurred. The radiologic evidence was consistent with the diagnosis of thrombosed aneurysm of the right intracavernous carotid artery, surrounded by sphenoidal mucocele. The patient underwent an endoscopic endonasal transsphenoidal approach exclusively for sphenoid mucocele drainage. Conclusion Although rare, the presence of a vascular lesion inside the sphenoid sinus has to be considered among the possible diagnostic hypotheses of masses abutting in this cavity; the association with mucocele is even more rare and, to date, has not been described.

    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. PMID:26415653

    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 sphenoid and the posterior ethmoid sinuses are surrounded by more vital structures than any other sinus. With the widespread acceptance and expanding role of endoscopic sinus surgery, a proper understanding of the anatomy of the sphenoid and the posterior ethmoid sinuses is achieved. We reviewed 100 CT studies of the paranasal sinuses belonging to patients examined for a chronic inflammatory disease of the nasal cavity and the paranasal sinuses. The relationship between the optic nerves and the paranasal sinuses is classified into four discrete categories. Type 1 with a proportion of 64% is observed to be the most often localized optic nerve. Type 2 is detected in 22% of the cases; types 3 and 4 are both 7% of the total number. A bony dehiscence was detected in 13.5% of the total cases, while it was observed in 39% of type 2 and 43% of type 3. We found a pneumatization of the anterior clinoid process in 11% of the patients. The proportion of pneumatization of the anterior clinoid process in type 3 configurations is found out to be as high as 86%. Optic nerve dehiscence was seen with a proportion of 23% in cases of pneumatization of the anterior clinoid process. Pneumatization of the posterior nasal septum was detected in 15% of the 100 cases. When the optic nerves were evaluated in these cases, mostly the type 1 configuration with a proportion of 63% was observed. An extensively pneumatized sphenoid sinus was detected in 4% of the 100 cases. Five of the investigated 8 optic nerves of these 4 cases were found out to be type 3 (62.5%). No significant optic nerve variations were met in patients with pneumatization of the posterior nasal septum. Nevertheless while performing surgery, it is important to bear in mind that there may be significant optic nerve variations with pneumatization of the anterior clinoid process and extensively pneumatized sphenoid sinuses.

    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.

  4. 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. PMID:23803589

    The occurrence of central nervous system metastases in ovarian cancer patients ranges from 0.88 to 4.5%. Centra nervous system involvement in a fallopian tube carcinoma is extremely rare. A 77-year-old woman with an invasive tubal carcinoma was admitted because of ophthalmoplegia, sparing the lateral rectus muscle of the left eye, a decreased left corneal reflex and hypoesthesia along the distribution of the ophthalmic and maxillary branches of the left trigeminal nerve. CT scan showed a space occupying lesion in the left sphenoid sinus invading the left cavernous sinus and the submucosa of the left lateral wall of the nasopharynx, proven histologically to be a metastasis from her primary cancer. Attention should be paid to the possibility of distant and unusual metastases associated with tubal cancer in order to treat the patients promptly. PMID:8171748

    Purpose: To test the hypothesis that in patient with sunken eyes, sagging brain syndrome, bone remodeling is not limited to the orbits. Volumetric analysis of the sphenoid sinus is performed in this study. Methods: In this university-based retrospective case-control study, the dimensions of the sphenoid sinus were measured in four patients (2 males, 2 females; mean age 26.3 years, range 16–38 years) out of five individuals identified with sunken eyes, sagging brain syndrome. Three measurements were taken: the distance between the orbital apices, the posterior extension of the sphenoid sinus posterior to the orbital apices, and the maximal horizontal width. The mean of each was determined and compared to that of the control group (5 males, 5 females; mean age 35.6 years, range 23–45 years). Results: Posterior extension and width of the sphenoid sinus were markedly larger in the enophthalmic patients than in the control group: posterior extension (26.3±4.1 mm vs 13.4±6.3 mm, P=.0015, Student’s t test), width (39.2±8.7 mm vs 25.1±6.9 mm, P=.0035, Student’s t test). Mean distance between the orbital apices was slightly greater (36.3±1.7 mm vs 34.1±2.1 mm, P=.047, Student’s t test). Conclusions: Skull remodeling occurring in association with intracranial hypotension after ventriculoperitoneal shunting is not limited to the orbits. In this study we have demonstrated expansion of the sphenoid sinus. This finding adds to our knowledge and understanding of the scope of the sunken eyes, sagging brain syndrome and elucidates a clinically useful radiographic sign. PMID:24167328

    The term fibro-osseous lesion has currently grown in popularity as an overall designation for a number of rare, histologically benign head and neck lesions that are made up of bone, fibrous tissue and cementum. Cemento-ossifying fibroma is a variant of cementifying fibroma and is a fibro-osseous disease. They are usually small innocuous lesions which follow a slow benign course and are commonly seen in the skull bone rather than the sphenoid. It is rare for these tumours to attain large size, behave aggressively, destroy bone and require a radical surgery. One such rapidly growing juvenile cemento-ossifying lesion of sphenoid in our 10-year-old young patient causing proptosis and impaired vision is reported here because of its uncommon nature and its surgical dilemma. Selection of surgical approach to resect this tumour becomes difficult because it is deeply seated and needs a multidisciplinary approach. PMID:24285811

    Cavernous sinus syndrome is a rare entity in oncology reported only in occasional case reports. Optimal therapy is thus poorly defined with rapidly progressive disease dominating the picture. Management includes prompt diagnosis, attempts at stabilization of cranial nerve function, and aggressive control of central pain syndrome. Here, we report cavernous sinus syndrome secondary to the original squamous cell carcinoma of the lung. With common presenting causes of this syndrome being infection, thrombosis or tumor, it might seem that metastatic tumor would be expected in a patient with a cancer diagnosis. What was not so expected was the extremely rapid progression from mild headache and mild trigeminal neuralgia with negative-contrast head CT to a massive, destructive lesion involving several skull bones and skull base, only 3 weeks later. In addition, the patient was severely immunosuppressed at the completion of induction chemotherapy. Infectious processes, although unlikely, were considered, as aggressive cancer therapy (including high-dose steroids and radiation therapy) had no impact on this disease. Despite accurate localization, the aggressive nature of this disease with massive bone destruction and dural thickening limited any chance of a durable control. We discuss the process of evaluation, diagnosis and treatment of symptoms and the importance of a team approach to best palliate these unfortunate patients. PMID:22379475

    This article describes a 22-year-old man who presented to the Howard University Hospital emergency room with acute onset of swelling, proptosis, and decreased vision in the right eye preceded by 24 hours of nausea and vomiting. The patient's visual acuity was count fingers in the involved eye with marked proptosis and limitation of ocular motility. There was no history given of any ocular or head trauma. A computed tomography scan of the orbits showed diffuse symmetric enlargement of the extraocular muscles of the right eye, felt to be consistent with an orbital inflammatory pseudotumor. The patient was treated with intravenous steroids initially, then placed on oral prednisone. After minimal improvement on the steroids, a selective external carotid angiogram showed a moderate-sized dural cavernous sinus fistula. The patient underwent selective embolization of the fistula with rapid resolution of periorbital edema and proptosis. Visual acuity was stabilized at 20/200 in the right eye. The differential diagnosis and pathogenesis of carotid cavernous sinus fistulas and the likely pathogenesis of the fistula in this case are discussed. Images Figure 1 Figure 2 Figure 3 PMID:8046763

    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

    Mucoceles of the paranasal sinuses are benign, chronic, expanding lesions that characteristically develop because of obstruction of the sinus ostium. The frontal sinus is the most common sinus to be affected by a mucocele, which usually results from trauma or inflammatory processes. Patients with these lesions frequently present with visual complaints of decreased visual acuity, visual field abnormalities, proptosis, ptosis, displacement of the globe, or restricted ocular movements secondary to erosion through the thin bone of the superior orbit and compression on the globe. Often, intracranial extension of frontal sinus mucoceles is also present from erosion through the posterior table of the frontal sinus. Very rarely, they will present as a subcutaneous forehead mass or swelling. To the best of our knowledge, only 5 cases of a frontal sinus mucocele presenting as a forehead subcutaneous mass has been previously reported. We report the case of an 80-year-old woman with a history of remote forehead trauma who presented with a frontal sinus mucopyocele manifesting as a subcutaneous forehead mass eroding through the skin.

Fundus examination revealed established optic atrophy in right eye with features of chronic papilloedema in left eye suggestive of compressive lesion. CT of brain, paranasal sinuses confirmed the presence of homogenously enhancing mass in left ethmoid sinus, left sphenoid sinus extending into suprasellar region. The biopsy of this mass revealed extra nodal SHML with tissue sections being S100 and CD68 positive with emperipolesis noted. Here we describe this atypical ocular presentation of extra nodal SHML to highlight that this rare disease can manifest as an aggressive sight threatening entity, even in older age group.

    2012-11-01

    A 58-year-old white woman presented with sudden onset of diplopia, headache and vomiting with a history of tiredness and lethargy over the past four to six months. She had smooth, pale, hairless skin and on examination she was found to have left-sided third and sixth nerve palsy. Laboratory tests confirmed pan-anterior hypopituitarism. Computerized tomography scan of head and magnetic resonance imaging appearances were consistent with those of a sphenoid sinus mucocoele. Following adequate replacement with hydrocortisone and thyroxine she underwent sphenoid mucocoele drainage and endoscopic left sphenoethmoidectomy. Her symptoms were relieved over the next few days and she had a near-total recovery of ophthalmoplegia over the following three months. Pituitary function tests showed partial resolution of hypopituitarism with recovery of hypothalamic-pituitary-adrenal axis and hydrocortisone therapy was withdrawn, but she continued to require thyroxine.

  18. Clinical presentation of inappropriate sinus tachycardia and differential diagnosis.

    PubMed

    Peyrol, Michael; Lévy, Samuel

    Inappropriate sinus tachycardia (IST) is a syndrome characterized by a sinus tachycardia not related to a medical condition, to a physiological response, or to medication or drugs and associated with symptoms, often invalidating and altering the quality of life of affected patients. It occurs predominantly in adolescents and young adults, and in the female sex. The diagnosis requires a complete work-up in order to exclude other causes of sinus tachycardia and one or several additional tests: 24-h ECG ambulatory recordings, echocardiogram, exercise testing, and autonomous nervous system assessment. It should be differentiated from the postural orthostatic tachycardia syndrome, with which it shares a number of symptoms, and other supraventricular tachycardias originating in the high right atrium. An electrophysiological study should be considered in selected cases in order to differentiate IST from other supraventricular tachycardias. The mechanism is still unclear, and possible etiologies may include intrinsic abnormality of the sinus node, autonomic dysfunction, hypersensitivity of the sinus node to catecholamines, blunted vagal system, or a combination of the above. The authors emphasize the wide spectrum of clinical presentations and the need to better define the IST and the criteria required to ascertain its diagnosis. PMID:26329720

    We report a case of primary endodermal sinus tumor of the omentum which may be the fourth reported case in the English literature. A 19-year-old boy presented with ascites. Analysis of ascites revealed high levels of AFP and CA 125. Laparoscopic biopsy showed endodermal sinus tumour. He was treated with four courses of the BEP regimen (bleomycin, etoposide, cisplatin). The patient was died 2 months after the first appearance of the ascites. Endodermal sinus tumor (EST) is a rare neoplasm which usually arises in the testis or ovary. But extragonadal EST especially located in the abdomen is very rare condition. Clinicians should remain vigilant particularly, when there is a low gradient ascites and are high levels of tumor markers in ascites in young patients.

  20. Upper Nasopharyngeal Corridor for Transnasal Endoscopic Drainage of Petroclival Cholesterol Granulomas: Alternative Access in Conchal Sphenoid Patients

    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

    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.

    Background and Purpose Aneurysmal bone cysts (ABCs) rarely involve the cranium and have seldom been reported in pregnancy. Clinical Presentation We describe a case of a 28-year-old woman who presented at 37 weeks of gestation with 3 months of gradually worsening vision, 10 months of proptosis, and restricted ocular motility on the left. Brain imaging revealed a multicystic enhancing mass measuring 5.9 × 5.3 × 3.7 cm, centered on the cribriform plate on the left, extending into the anterior cranial fossa superiorly as well as the left nasal cavity, maxillary, sphenoid, and frontal sinuses. Her clinical course is described in detail; 3-month postoperative imaging demonstrated no residual mass. Conclusion A literature review revealed five previous cases of ABCs associated with pregnancy. We report a rare case of a giant ABC of fibrous dysplasia involving the paranasal sinuses and anterior cranial fossa. We postulate on the possible influence of pregnancy on the clinical course.

    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

    Spindle cell carcinoma (SpCC) is a rare variant of squamous cell carcinoma (SCC). SpCC of sinonasal origin is relatively rare and more aggressive than normal SCC. It most commonly involves the maxillary sinus, and rarely the sphenoid sinus. The present study reports a case of sphenoid sinus SpCC presenting with bilateral visual loss. Following endoscopic sinus decompression surgery, the patient was referred to the Oncology Department for a staging workup, and subsequently received concurrent chemoradiotherapy; however, the vision of the patient was not recovered, despite treatment. To the best of our knowledge, this is the first reported case of synchronous inverted papilloma of the sphenoid sinus and SpCC presenting with optic nerve compression. PMID:27347158

    Cavernous sinus thrombosis is a rare but serious complication of sphenoid aspergillosis. The rarity of this pathology makes its diagnostic very difficult on a clinical, biological and radiological sense. The authors present a case of cavernous sinus thrombosis with ipsilateral internal carotid artery thrombosis secondary to a non-invasive sphenoid aspergillosis in an immunocompetent host, responsible of a cavernous syndrome associated to a Claude Bernard Horner syndrome. One year after surgery, the patient is still asymptomatic without recurrence. Diagnostic modalities are detailed and several management of this pathology are compared. Surgery is essential in a diagnostic and therapeutic sense. There is no evidence of the interest of adjuvant therapies such as antibiotic and anticoagulation. Concerning the antifungal treatment, the attitude towards a non-invasive sphenoid aspergillosis in an immunocompetent host is unclear. PMID:26860234

    Many mammal skulls contain air spaces inside the bones surrounding the nasal chamber including the frontal, maxilla, ethmoid, and sphenoid, all of which are called paranasal sinuses. Within the Carnivora, frontal sinuses are usually present, but vary widely in size and shape. The causes of this variation are unclear, although there are some functional associations, such as a correlation between expanded frontal sinuses and a durophagous diet in some species (e.g., hyenas) or between absent sinuses and semiaquatic lifestyle (e.g., pinnipeds). To better understand disparity in frontal sinus morphology within Carnivora, we quantified frontal sinus size in relationship to skull size and shape in 23 species within Arctoidea, a clade that is ecologically diverse including three independent invasions of aquatic habitats, by bears, otters, and pinnipeds, respectively. Our sampled species range in behavior from terrestrial (rarely or never forage in water), to semiterrestrial (forage in water and on land), to semiaquatic (forage only in water). Results show that sinuses are either lost or reduced in both semiterrestrial and semiaquatic species, and that sinus size is related to skull size and shape. Among terrestrial species, frontal sinus size was positively allometric overall, but several terrestrial species completely lacked sinuses, including two fossorial badgers, the kinkajou (a nocturnal, arboreal frugivore), and several species with small body size, indicating that factors other than aquatic habits, such as space limitations due to constraints on skull size and shape, can limit sinus size and presence.

    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.

    Hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. We report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. Although computed tomography (CT) and magnetic resonance imaging (MRI) showed several enhancing areas within the tumor, the substantial bone erosion and remodeling made it difficult to differentiate this cavernous hemangioma from other expansile maxillary sinus lesions. We present the CT and MR findings of this lesion and discuss the differential diagnoses and potential therapeutic approaches. PMID:25901262

    Sinus barotrauma is usually easy to diagnose, and treatment achieves good results. We present two severe cases where delayed diagnosis caused significant morbidity. The signs and symptoms were atypical and neither the patients themselves, nor the initial examiners recognized that the onset of symptoms coincided with descent in a commercial airliner. CT and MRI scans of the brain were normal, but in both cases showed opafication of the sphenoid sinuses, which lead to the correct diagnosis. Subsequent surgical intervention consisting of endoscopic computer-aided surgery showed blood and petechia in the affected sinuses. This procedure provided immediate relief.

    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

    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.

    Fibro-osseous lesions of the face and paranasal sinuses are relatively uncommon. These lesions have overlapping clinical, radiologic and pathologic features causing difficulty in diagnosis. Neoplastic fibro-osseous paranasal sinus lesions can be benign or malignant. The benign fibro-osseous lesions described are: ossifying fibroma (and its histologic variants) and fibrous dysplasia. The variants of ossifying fibroma differ in the nature of calcified material (i.e. cementum versus bone), in the location of the lesion (oral versus paranasal sinus or orbital), other morphologic variations (presence of psammomatoid concretions) and biologic behavior (aggressive versus stable). Presence of cementum or bone classifies the lesion as cementifying fibroma or ossifying fibroma respectively while lesions with mixture of both cementum and bone are called cemento-ossifying fibroma. We describe a case of a young adult male with cemento-ossifying fibroma of paranasal sinus presenting acutely as left orbital cellulitis with proptosis.

    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

    Human infections due to Aspergillosis Fungi are unusual and occur preferentially in defenseless patients. Nonetheless, our patient, a seed-shop owner, was not immuno-depressed and became infected by inhaling or chewing the seeds. Moreover, the aspergillosis was situated in the sphenoidal sinus, which is extremely unusual. In fact, the initial pseudo tumoral and misleading appearance justified a surgical biopsy which revealed a black "truffle" suggestive of aspergillosis and was confirmed by anatomo-pathology.

    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

    Transverse-sigmoid sinus dural arteriovenous malformations (DAVM) are uncommon vascular lesions for which complete cure may be difficult to obtain. A wide variety of treatments for these lesions include observation, arterial compression, surgical resection, and endovascular embolization. We propose that transverse-sigmoid sinus DAVM can be completely cured by occluding the ipsilateral dural sinus with detachable balloon and Guglielmi detachable coils (GDC) coils before arterial feeder embolization with histoacryl. Three patients who presented with pulsatile tinnitus and normal magnetic resonance imaging (MRI) studies underwent angiography, which demonstrated transverse-sigmoid sinus DAVM. All three patients wer treated with retrograde transvenous sinus embolization with complete occlusion of the transverse-sigmoid sinus with detachable balloons and GDC coils with preservation of the vein of Labbé. Subsequently, the various feeders from the external carotid artery were embolized. The tentorial arteries arising from the ipsilateral internal carotid arteries were not embolized in any of the cases, which were still contributing to the DAVM. Complete cure with thrombosis of the tentorial branch of the internal carotid artery (ICA) was seen on follow-up angiogram 1 day after embolization in one patient and on 4-week and 6-week follow-up angiograms in the other two patients. Complete occlusion of the transverse sinus proximal to the vein of Labbé, in spite of incomplete arterial feeder embolization, can result in complete cure of the transversesinus dural AVF if adequate time is given for the remaining feeders to occlude, once the fistula is obliterated.

    Introduction: A pneumocele is an abnormal dilation of an air-containing sinus beyond the normal margins of bone, with associated bony thinning. 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.

    Acute bacterial sinusitis is a common disease in the pediatric population that typically resolves without significant complications. Children who do suffer from complications involving the orbit or the brain often experience significant morbidity and potential mortality, typically requiring hospitalization for management. Numerous studies have demonstrated that children from low-income families with public or no insurance are less likely to receive adequate preventative care, are more likely to present with later disease stages, and ultimately endure worse health outcomes. We review the literature to examine if there are socioeconomic disparities in the presentation of complications of acute bacterial sinusitis in the pediatric population.

    The unusual case of dense in dente in mandibular molar area with extra oral sinus in a 30-year-old female is presented. The chief complaint of the patient was wound formation and pus discharge from the right side of lower jaw for many years. Clinical examination revealed extra oral sinus and mild swelling in vestibular region opposite the right mandibular molars. On radiographical examination, right mandibular third molar had bulbous root associated with periapical radiolucency. It appeared that there was a tooth within a tooth and the invagination extended nearly to the root apex. A clinical diagnosis of dense in dente Type III was confirmed by stereomicroscopy of ground section of the tooth. Extra oral sinus healed after extraction of the mandibular third molar within a month. PMID:21731269

    A 12-year-old boy with a history, at birth, of a weeping pink fleshy lesion after his umbilical cord detached, requiring repeated chemical cauterisation, presented with massive lower gastrointestinal bleeding and required resuscitation and blood transfusion. Augmented Tc99m nuclear medicine scan confirmed ectopic gastric mucosa. The lateral view suggested its attachment behind the umbilicus. At exploration, a latent vitellointestinal duct sinus with ectopic gastric mucosal mass was found. Segmental resection of the sinus and mass excision with primary anastomosis and incidental appendicectomy was curative. Pink fleshy mass discharging coloured fluid at the umbilicus following detachment of umbilical cord should be considered a remnant of vitellointestinal duct unless proved otherwise. A pink lesion with yellowish discharge resistant to chemical cauterisation should raise the suspicion of embryonic structures. Latent vitellointestinal sinus is a new lesion in the spectrum of umbilical anomalies. Lateral view of the nuclear medicine scan is helpful in locating the site.

    A 12-year-old boy with a history, at birth, of a weeping pink fleshy lesion after his umbilical cord detached, requiring repeated chemical cauterisation, presented with massive lower gastrointestinal bleeding and required resuscitation and blood transfusion. Augmented Tc99m nuclear medicine scan confirmed ectopic gastric mucosa. The lateral view suggested its attachment behind the umbilicus.

    Odontoma is a mixed odontogenic hamartoma involving both epithelial and mesenchymal tissues. If left untreated, it can lead to complications in certain conditions. Here is a rare presentation of an extensive complex odontoma in maxillary sinus pushing third molar near the orbital floor causing transient diplopia in upward gaze occasionally and chronic sinusitis. Although odontomata are not uncommon and are familiar to practitioners, but some aggressive cases may cause problematic sequelae. Even postoperative complications may result if oral surgeons are not aware of the potential pitfalls associated with the surgical removal of large maxillary antrum odontomata. This article reports a rare presentation which can be considered unique because when obstruction of sinus drainage is evident, serious complications such as orbital infections, epidural and subdural empyema, meningitis, cerebritis, cavernous sinus thrombosis, brain abscess and death can occur. It also addresses points and pitfalls concerning surgery to remove odontoma. PMID:25848139

    Congenital aneurysms of the sinus of Valsalva are uncommon abnormalities that are usually silent and slowly progressive without symptoms of cardiac dysfunction unless catastrophic rupture occurs. However, in rare cases, unruptured aneurysms can produce symptoms resulting from compression of adjacent structures, ventricular outflow tract obstruction, heart block, and coronary and valvular insufficiency. We report a case of a single unruptured sinus of Valsalva aneurysm producing left ventricular outflow tract obstruction in an 8-year-old boy who presented with chest pain on exertion.

    2012-01-01

    The case of a 59-year-old Caucasian man who presented with a 6-week history of intermittent blurring of vision and diplopia is reported. Fundoscopy revealed asymmetrical, bilateral optic disc swelling with peripapillary haemorrhages. An initial CT scan and D-dimer level were reported as normal. A subsequent MRI revealed a recanalising superior sagittal sinus thrombosis. Cerebral venous sinus thrombosis is a rare and potentially fatal condition. The author suggests that it should be part of the differential diagnosis of bilateral optic disc swelling and that a normal unenhanced CT scan and D-dimer would not rule out this potentially devastating condition.

    Thrombosis is a well recognized complication of inflammatory bowel disease that occurs in 1.3 to 6.4% of patients, however, cerebral vascular involvement is unusual. We present the case of a 16-year-old female in whom cerebral venous thrombosis was the presenting symptom of an active ulcerative pancolitis. Thrombophilia screen (plasma levels of proteins C and S, antithrombin, antibeta2-glycoprotein, lupus anticoagulant and anticardiolipin antibodies, activated protein C resistance, homocystein level antinuclear antibodies) was negative. The patient was successfully treated with anticoagulant therapy, phenobarbital and sulfasalazine. Cerebral venous thrombosis is an exceptional presenting feature of ulcerative colitis. Disease activity may play a major role in the occurrence of thrombosis. PMID:19902870

    Mucoceles of the sphenoidal and ethmoidal sinuses act as benign neoplasms and can result in bony erosion extending from within the confines of the sinuses into the intracranial and orbital spaces. Endoscopic management of such mucoceles has been debated, and, by some, considered a radical form of therapy. A review of consecutive patients with sinus mucoceles revealed eight sphenoid and six ethmoid mucoceles. Four of these were confined to the sinuses and 11 extended outside of the confines of the sinuses. There were four with intracranial extension, two with orbital extension, three with both intracranial and orbital extension, and two involving the clivus. All 15 patients were managed with endoscopic decompression. Two patients with ethmoid-frontal mucoceles also had frontal sinus obliteration, via an osteoplastic flap along with sphenoethmoidal decompression with an endoscopic approach. Thirteen patients had more than one year of follow-up. Two patients with ethmoid mucoceles with intracranial extension had recurrences of the mucoceles which again have been decompressed endoscopically. There were no orbital or intracranial complications in relationship to these procedures or from the mucoceles. Symptoms related to the mucoceles including loss of vision and severe headaches were resolved with decompression. The endoscopic management of sphenoid and ethmoid mucoceles with orbital and intracranial extension is a safe and reliable approach, obviates the need for major intracranial surgery and diminishes post-operative morbidity. Close follow-up is necessary and secondary decompression can be accomplished should the mucocele recur.

    Septo-optic dysplasia (SOD) is an extremely rare congenital anomaly, characterized with optic nerve hypoplasia and absence of septum pellucidum and/or pituitary dysfunction. In addition to classical findings of SOD, we report for the first time an 11-year-old boy, with encephalocele extending to the right sphenoidal sinus, right anophthalmia and normal pituitary functions. Despite all the major anomalies, the patient's presenting symptoms were very few and during the 11-year period the SDO had caused no complaints in our case. These findings show that the SOD course may be fairly benign. No neurological problem was encountered in the patient's follow-up, except headache. We believe that SOD should be kept in mind because of its rarity and the severity of its combined pathologies.

    This case report details an association of chronic allergic conjunctivitis and respiratory tract colonization in a cystic fibrosis (CF) patient due to an ethmoidal mucocele infected with Escherichia coli. A 3-year-old CF patient presented for evaluation with complaints of chronic periocular erythema, conjunctival injection, and irritation for 2 years. He was treated for presumed allergic conjunctivitis with no improvement and continued to have overall worsening of symptoms on the right greater than the left eye in a waxing and waning pattern. On presentation to the Bascom Palmer Eye Institute, he was noted to have telecanthus and prominent erythema in the region of the medial canthus. Orbital imaging disclosed a mucocele in the right ethmoid sinus. The patient underwent functional endoscopic sinus surgery, with successful marsupialization of the ethmoidal mucocele, which was found on culture to be infected with E. coli. Post-operatively with continuous pulmonary care, the patient remains free of allergic conjunctivitis and E. coli colonization of the upper airway. This case highlights the importance of analyzing the adjacent sinus in patients with chronic, relapsing allergic conjunctivitis refractory to medical management, particularly in patients with underlying systemic diseases such as CF.

    Antrochoanal polyp is a benign polypoid lesion orginating from the maxillary sinus antrum and extending to the choana. Our aim was to assess the clinical presentation and associated rhinological findings of antrochoanal polyp patients and to evaluate results of 2 surgical treatments termed endoscopic sinus surgery (ESS) and ESS plus mini-Caldwell operation. The study included 46 patients. Factors such as patient age, sex, history of chronic sinusitis, allergic rhinitis, septal deviations, chonca bullosa, turbinate hypertrophy, and the origin of the polyp were assessed. We also evaluated ESS and ESS plus mini-Caldwell surgical procedures for recurrences, synechia, bleeding, and ostium stenosis. Overall, there were 27 men and 19 women. The ESS approach was used in 26 cases, and 20 cases had combined ESS and mini-Caldwell procedures. The statistical significant difference between the 2 groups was only recurrence (P < 0.05). In the ESS group, bleeding, synechia, and ostium stenosis were seen more than in the ESS + mini-Caldwell group, but there was no significant difference between the 2 groups in bleeding, synechia, and ostium stenosis (P > 0.05). We thought that lower rate of recurrence found in ESS + Caldwell group in this study was associated with better visualization of the maxillary sinus walls and, therefore, easier resection of the remnant polyp. We concluded that higher incidences of bleeding and synechia were related to the mucosal damage occurring in the septum and the inferior concha due to excessive manipulation of endoscope and surgical instruments.

    An otherwise serious and potentially fatal organic condition may present with a co-existing strong functional component. We encountered a female patient who presented with bouts of severe headache over the occipital region, associated with blurring of vision. Initially, non-contrast computed tomography (CT) scan (Brain) showed normal study, and she was deemed as having functional symptoms. Later, magnetic resonance imaging (MRI) (Brain) showed filling defect in right sigmoid sinus and magnetic resonance (MR) venography confirmed right sigmoid sinus thrombosis. On adequate anticoagulation, she did not improve and still had bouts of severe headache, although no longer associated with impaired vision. The treating neurophysician concluded that symptoms could no longer be accounted for by the organic condition. Overt and covert psychosocial stressors were found to be present in a detailed psychological exploration. Psychological intervention effectively controlled the headache. Thus, functional overlay can complicate the clinical picture in a severe organic condition and may require active psychiatric intervention over and above medical treatment.

    Aspergillosis is an opportunistic deep mycosis that occurs in immunocompromised patients, often in the paranasal sinuses. However, it sometimes occurs in healthy subjects, producing symptoms similar to those of a chronic sinusitis that is unresponsive to conventional treatment. A possible entry point for Aspergillus is the oroantral communication originated by perforation of the dental root cavity during root canal of a molar with penetration of material. We report the clinical case of a patient with symptoms of chronic sinusitis who was diagnosed as sinus aspergillosis after radiological and histological study. The origin may have been a third upper molar in which a root canal was performed. PMID:9717333

    Cemento-ossifying fibromas are benign lesions of the jaw, which arise from the periodontal membrane. Histopathologically these are composed of fibrous tissues with calcified structures resembling bone and cementum. Surgical resection is the treatment of choice. They have rarely been reported in the ethmoid sinus, maxillary sinus and sphenoid sinus Mastoid bone is an extremely rare site of such tumors. Only one case of cemento-ossifying fibroma of petromastoid bone has been reported before. We present a case of cementoossifying fibroma involving the petromastoid bone, with the large intracranial component causing compression on the cerebellum. This unique case may provide insight into the etiopathogenesis of these tumors.

    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.

    The one-piece orbitozygomatic (OZ) approach is traditionally based on the McCarty keyhole. Here, we present the use of the sphenoid ridge keyhole and its possible advantages as a keyhole for the one-piece OZ approach. Using transillumination technique the osteology of the sphenoid ridge was examined on 20 anatomical dry skull specimens. The results were applied to one-piece OZ approaches performed on freshly frozen cadaver heads. We defined the center of the sphenoid ridge keyhole as a superficial projection on the lateral skull surface of the most anterior and thickest part of the sphenoid ridge. It was located 22 mm (standard deviation [SD], 0.22 mm) from the superior temporal line; 10.7 mm (SD, 0.08 mm) posterior and 7.1 mm (SD, 0.22 mm) inferior to the frontozygomatic suture. The sphenoid ridge burr hole provides exposure of frontal, temporal dura as well as periorbita, which is essential for the later bone cuts. There is direct access to removal of the thickest (sphenoidal) part of the orbital roof, after which the paper-thin (frontal) part of the orbital roof is easily fractured. The sphenoid ridge is an easily identifiable landmark on the lateral skull surface, located below the usual placement of the McCarty keyhole, with comparative exposure. PMID:27175313

    Introduction: A mucocele is an epithelial-lined, mucus-containing sac that can fill the sinus completely and expand gradually. Mucopyocele is an infected mucocele. Case Report: We presented a case of left maxillary mucopyocele in a 58-year-old man that developed after radiotherapy for nasopharyngeal carcinoma. Computed tomography scan showed opacification of the left maxillary sinus expanding through the medial wall of the antrum with thinning and destruction of the adjacent structures. Endoscopic marsupialization of the lesion and left partial maxillectomy were performed. The cystic mass had yellowish thick mucopurulent fluid that was completely drained. Conclusions: A few cases of sphenoid sinus mucocele as a late complication of radiation therapy have been reported. Maxillary mucocele and mucopyocele can be considered as one of the late complications of radiotherapy to head and neck as a result of occlusion of sinus ostia by scarred mucosa. PMID:25237579

    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.

    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.

    Maxillary sinus hypoplasia is rare, with an estimated prevalence of 1-5%. Out of the CT scans performed in sinusal patients between March 1998 and June 1999, we report on 4 isolated maxillary sinus hypoplasia, 4 maxillary sinus hypoplasia associated to concha bullosa, and 10 isolated conchae bullosas. All cases were evaluated by nasosinusal endoscopy and CT scan. Size, location and uni/bilateral presentation of concha bullosa is correlated to maxillary sinus hypoplasia presence, specially with regards to uncinate process presence, medial or lateral retraction. The pathogenesis of maxillary sinus hypoplasia is reviewed, and its relation to concha bullosa, evaluating how this could explain some cases of the so called chronic maxillary sinus atelectasia, as an acquired and progressive variant of maxillary sinus hypoplasia in adults.

    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

Trans-thoracic echocardiography (TTE) suggested an unruptured right sinus of Valsalva aneurysm (SVA) causing extrinsic compression of the right ventricular outflow tract. This was confirmed with an ECG-gated cardiac CT showing a large right SVA measuring 35×37×42 mm in size. Coronary angiography demonstrated non-obstructive coronary artery disease. Ascending thoracic anterior in the right anterior oblique view delineated the right SVA. The patient underwent aortic valve sparing surgical repair of the aneurysm with an excellent result. Echocardiography confirmed obliteration of the aneurysm and normal aortic valve function postoperatively. PMID:23008378

    2016-01-01

    Background: Currently, there is no uniform consensus regarding the appropriate staging for invasion of the paranasal sinuses in nasopharyngeal carcinoma (NPC). In the current AJCC staging system for NPC, paranasal sinus invasion is defined within the T3 classification. However, according to the Chinese 2008 staging system, which is also widely used in the regions where NPC is endemic in China, paranasal sinus invasion is classified as T4 disease. Methods: Patients (n = 1811) with non-metastatic, histologically-proven NPC treated with intensity-modulated radiotherapy (IMRT) were retrospectively analyzed. Results: Paranasal sinus invasion was identified in 289/1811 patients (16.0%). Multivariate analysis revealed ethmoid sinus invasion (HR, 2.889; 95% CI, 1.362-6.131; P = 0.006) and maxillary sinus invasion (HR, 3.110; 95% CI, 1.439-6.721; P = 0.004) were independent prognostic factors for local relapse-free survival (LRFS). T3 patients with ethmoid sinus or maxillary sinus invasion had similar 3-year LRFS (83.6% vs. 92.2%, P = 0.132) as T4 patients, and had poorer LRFS (83.6% vs. 98.3%, P = 0.006) than T3 patients with sphenoid sinus invasion alone. Also, T3 patients with sphenoid sinus invasion alone had similar 3-year LRFS (98.3 vs. 96.4%, P = 0.391) as T3 patients without paranasal sinus invasion, and a trend toward higher LRFS (98.3% vs. 92.2%, P = 0.065) than T4 patients. Conclusion: In patients underwent IMRT, tumors with ethmoid sinus or maxillary sinus invasion had a higher risk of local failure than those with sphenoid sinus invasion alone. Sphenoid sinus invasion alone should be classified as T3 disease and ethmoid sinus or maxillary sinus involvement as T4 disease in the current AJCC staging system for NPC. PMID:27390611

    The authors present a case of a previously healthy 8-year-old girl who presented with pain on the right side of the nose (bony part) radiating to the frontal and temporal regions. Physical examination was normal, whereas magnetic resonance imaging (MRI) of the facial region revealed a tumor limited to the right ethmoidal sinus with a small extension to the medial wall and the upper part of the nasal septum. The tumor was removed by using a 5-degree nasoscope and sent for pathologic examination, which revealed a cemento-ossifying fibroma of the ethmoidal sinus. This is a rare condition, and MRI is a valuable tool in its detection because results of physical examination may be normal in patients reporting nasal pain. According to the World Health Organization classification, this tumor is a variant of cementifying fibromas, which represent a subgroup of cementomas, fibro-osseous lesions containing cementum. Cementifying fibromas are rare tumors. They are usually small, asymptomatic lesions, but although benign, they can develop into aggressive, expansible masses.

On the evidence mounted from 190 patients with paranasal sinus, the computer tomography semiotics of various chronic inflammatory processes in sinus has been developed and the comparative analysis of computer tomography and classic X-ray and ultrasonic scanning of sinus has been fulfilled. The computer tomography appears to have high diagnostic potentials for revealing pathology in paranasal sinus in flying personnel. It was confirmed that the technique enables to examine normal anatomy of paranasal sinus, support or invalidate previous diagnosis, and to ascertain the spread and the character of process, visualize alterations in soft and bone tissues and plan surgery.

    The relationship of paranasal sinusitis to optic neuritis remains an intriguing curiosity to both the otolaryngologist and the ophthalmologist. The literature is replete with anecdotal case reports of patients whose sinusitis appears to have caused optic neuritis. There is much speculation about the pathophysiological mechanisms which relate these two distinct disease entities. Five new cases are described which highlight distinct pathophysiologic routes through which paranasal sinus disease has caused optic neuritis. These include compressive optic neuropathy secondary to mucoceles and/or pyoceles; direct extension of sinus infection to the optic nerve from suppurative paranasal sinusitis; and, in one case, from osteomyelitis of the ethmoid and sphenoid sinuses. The usefulness of computerized axial tomography of the orbits and paranasal sinuses to evaluate optic neuritis and to elucidate in detail the pathophysiology of its relationship to disease of the paranasal sinuses is emphasized. Currently, optic neuritis is felt to be a rare complication of paranasal sinusitis. Paranasal sinus surgery is advocated in those cases where sinus suppuration is suspected, or when a compressive optic neuropathy is caused by a sinus mucocele or pyocele. Since in most cases, however, optic neuritis is self-limited, it is difficult to evaluate the results of surgery in circumstances other than those mentioned already. Continued careful evaluation, management, and documentation of this group of patients is necessary to help better define the relationship between these two disease entities.

    A 39-year-old hypothyroid woman on thyroxine replacement therapy presented with an unresolving episode of palpitations (narrow-complex tachycardia). Clinical examination, after reversion to normal sinus rhythm revealed a precordial continuous murmur. Initial transthoracic echocardiogram showed an unruptured aneurysm of left sinus of Valsalva (LSOV), however, because a continuous murmur could not be explained by this condition, a repeat colour Doppler study was made, revealing a communicating tract from the left main coronary artery (LMCA) and terminating in the right atrium (RA). A transesophageal echocardiogram revealed an aneurysmal LMCA and LSOV, with similar colour Doppler findings. A further CT scan and coronary angiogram confirmed a coronary cameral fistula opening into RA. In conclusion, the relevance of a diligent clinical examination and imaging after conversion to normal sinus rhythm in picking up such anomalies cannot be over-emphasised, as previous routine echocardiograms on the same patient had been reported as normal.

    Objectives Chronic rhinosinusitis (CRS) is a common chronic disease of the upper airways and has considerable impact on quality of life. Topical delivery of drugs to the paranasal sinuses is challenging, therefore the rate of surgery is high. This study investigates the delivery efficiency of a pulsating aerosol in comparison to a nasal pump spray to the sinuses and the nose in healthy volunteers and in CRS patients before and after sinus surgery. Methods 99mTc-DTPA pulsating aerosols were applied in eleven CRSsNP patients without nasal polyps before and after sinus surgery. In addition, pulsating aerosols were studied in comparison to nasal pump sprays in eleven healthy volunteers. Total nasal and frontal, maxillary and sphenoidal sinus aerosol deposition and lung penetration were assessed by anterior and lateral planar gamma camera imaging. Results In healthy volunteers nasal pump sprays resulted in 100% nasal, non-significant sinus and lung deposition, while pulsating aerosols resulted 61.3+/-8.6% nasal deposition and 38.7% exit the other nostril. 9.7+/-2.0 % of the nasal dose penetrated into maxillary and sphenoidal sinuses. In CRS patients, total nasal deposition was 56.7+/-13.3% and 46.7+/-12.7% before and after sinus surgery, respectively (p<0.01). Accordingly, maxillary and sphenoidal sinus deposition was 4.8+/-2.2% and 8.2+/-3.8% of the nasal dose (p<0.01). Neither in healthy volunteers nor in CRS patients there was significant dose in the frontal sinuses. Conclusion In contrast to nasal pump sprays, pulsating aerosols can deliver significant doses into posterior nasal spaces and paranasal sinuses, providing alternative therapy options before and after sinus surgery. Patients with chronic lung diseases based on clearance dysfunction may also benefit from pulsating aerosols, since these diseases also manifest in the upper airways. PMID:24040372

    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

  3. The posterior border of the sphenoid greater wing and its phylogenetic usefulness in human evolution.

    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

    Cemento-ossifying fibroma is a lesion containing both fibrous and osseous components. Such lesions include fibrous dysplasia, ossifying fibroma, cemento-ossifying fibroma and cementifying fibroma. Periodontal membrane is the origin of fibro-osseous lesions other than fibrous dysplasia.Here a clinical case of a young woman referred for evaluation of a mass in the right side of face between eye and nose is presented. The first time she noticed the mass was 2 years ago and was growing larger inwards. She was treated with surgical resection.In this case of a cemento-ossifying fibroma, histological interpretation was critical, and was the basis of correct treatment.

    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

    Acute fulminant invasive fungal sinusitis is most commonly found in immunocompromised patients with conditions such as diabetes mellitus, malignancies and acquired immune deficiency syndrome. The most common pathogens are Aspergillus and Mucoraceae and the sinus most frequently involved is the maxillary sinus. Fever, rhinorrhea, facial pain, headache, and diplopia are common presenting symptoms. Complications of this infection include intracranial and / or intraorbital spread of the infection; the prognosis is poor. Here, a rare case of acute fulminant invasive fungal sinusitis with cavernous sinus syndrome is reported.

    Objectives To identify independent predictors of outcome in patients with adenoid cystic carcinoma (ACC) of the paranasal sinuses and skull base. Design Meta-analysis of the literature and data from the International ACC Study Group. Setting University-affiliated medical center. Participants The study group consisted of 520 patients, 99 of them from the international cohort. The median follow-up period was 60 months (range, 32 to 100 months). Main Outcome Measures Overall survival (OS) and disease-specific survival (DSS). Results The 5-year OS and DSS of the entire cohort were 62% and 67%, respectively. The local recurrence rate was 36.6%, and the regional recurrence rate was 7%. Distant metastasis, most commonly present in the lung, was recorded in 106 patients (29.1%). In the international cohort, positive margins and ACC of the sphenoid or ethmoidal sinuses were significant predictors of outcome (p < 0.001). Perineural invasion and adjuvant treatment (radiotherapy or chemoradiation) were not associated with prognosis. Conclusion Tumor margin status and tumor site are associated with prognosis in ACC of the paranasal sinuses, whereas perineural invasion is not. Adjuvant treatment apparently has no impact on outcome. PMID:24436900

    Fungal sinusitis is characterized into invasive and noninvasive forms. The invasive variety is further classified into acute, chronic and granulomatous forms; and the noninvasive variety into fungus ball and allergic fungal sinusitis. Each of these different forms has a unique radiologic appearance. The clinicopathologic and corresponding radiologic spectrum and differences in treatment strategies of fungal sinusitis make it an important diagnosis for clinicians and radiologists to always consider. This is particularly true of invasive fungal sinusitis, which typically affects immuno compromised patients and is associated with significant morbidity and mortality. Early diagnosis allows initiation of appropriate treatment strategies resulting in favorable outcome.

    Sinusitis is a common patient complaint that carries with it a large economic burden. It is one of the most common reasons patients visit their primary care physician. Acute bacterial rhinosinusitis (ABRS) can be distinguished from other forms of rhinosinusitis based on symptom duration of <4 weeks in a patient with purulent rhinorrhea associated with facial pain or pressure. Native upper aerodigestive tract bacteria are the most common etiologic agents. Treatment of ABRS is targeted primarily at symptom improvement. Amoxicillin can be used based on the clinical scenario and patient comorbidities. Computed tomographic scans are reserved for complicated presentations or when there is concern for intracranial extension or other complications. A systematic approach to ABRS will allow for improved patient quality of life and a decreased overall economic burden of this common entity.

  10. Cerebral venous sinus thrombosis

    Allroggen, H.; Abbott, R.

    2000-01-01

    Cerebral venous sinus thrombosis is a challenging condition because of its variability of clinical symptoms and signs. It is very often unrecognised at initial presentation. All age groups can be affected. Large sinuses such as the superior sagittal sinus are most frequently involved. Extensive collateral circulation within the cerebral venous system allows for a significant degree of compensation in the early stages of thrombus formation. Systemic inflammatory diseases and inherited as well as acquired coagulation disorders are frequent causes, although in up to 30% of cases no underlying cause can be identified. The oral contraceptive pill appears to be an important additional risk factor. The spectrum of clinical presentations ranges from headache with papilloedema to focal deficit, seizures and coma. Magnetic resonance imaging with venography is the investigation of choice; computed tomography alone will miss a significant number of cases. It has now been conclusively shown that intravenous heparin is the first-line treatment for cerebral venous sinus thrombosis because of its efficacy, safety and feasability. Local thrombolysis may be indicated in cases of deterioration, despite adequate heparinisation. This should be followed by oral anticoagulation for 3-6 months. The prognosis of cerebral venous sinus thrombosis is generally favourable. A high index of clinical suspicion is needed to diagnose this uncommon condition so that appropriate treatment can be initiated.

    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 algorithm of treatment of septic lateral sinus thrombosis (SLST) has undergone a paradigm shift with the understanding of the natural history of sigmoid sinus thrombosis. Thus, the recent medical literature promulgates the management of these cases with no sinus exploration. However, in view of marked paucity of literature on the cited subject, not much is known about this form of treatment. We present our experience of treating two paediatric cases of SLST with mastoid surgery and no sinus exploration: both cases had excellent recovery. Finally, conclusions are drawn in light of contemporary literature on this subject. PMID:26881164

    Background Sinus fungus ball, an accumulation of fungal dense concretions, is a common disease in practice, and might cause fatal complications or lead to death once converted into invasive type. Early preoperative diagnosis of this disease can lead to appropriate treatment for patients and prevent multiple surgical procedures. Up to now, the diagnostic criteria of sinus fungus ball have been defined and computed tomography (CT) scan was considered as a valuable preoperative diagnostic tool. However, the sensitivity of clinical CT is only about 62%. Thus, investigating the factors which influence sensitivity is necessary for clinical CT to be a more valuable preoperative diagnosis tool. Furthermore, CT scan usually presents micro-calcifications or spots with metallic density in sinus fungus ball. Previous literatures show that there are some metallic elements such as calcium and zinc in fungus ball, and they concluded that endodontic treatment has a strong correlation with the development of maxillary sinus fungus ball and zinc ion was an exogenous risk factor. But the pathogenesis of sinus fungus ball still remains unclear because fungus ball can also develop in other non-maxillary sinuses or the maxillary sinus without root canal treatment. Is zinc ion the endogenous factor? Study on this point might be also helpful for investigating the pathogenesis of sinus fungus ball. In this paper, we tried to investigate the factors which influence the sensitivity of clinical CT by imaging sinus fungus ball with microCT. The origin of zinc ion was also studied through elements test for different fungal ball samples using x-ray fluorescence technique. Methods Specimens including fungal ball material and sinus mucosa from patients confirmed by pathological findings were extracted after surgery. All fungal ball specimens came from sphenoid sinus, ethmoidal sinus and maxillary sinus with or without previous endodontic treatment respectively. All of them were imaged by micro

    2012-01-01

    Pilonidal disease is a disease of young people, usually men, which can result in an abscess, draining sinus tracts, and moderate debility for some. It probably results from hair penetration beneath the skin, for reasons that are not totally clear. A pilonidal sinus in the sacrococcygeal region is associated with recurrent infection, abscess formation, cellulitis, and fistulae. The infection is usually chronic and non-specific. However, few reports of granulomatous infection like tuberculosis and actinomycosis in pilonidal sinus have been observed. The presentation of tuberculosis in these sinuses may have wide forms, with atypical and uncharacteristic clinical picture, making it difficult to make a diagnosis preoperatively. This paper discusses about pilonidal sinus disease and tubercular infiltration in these sinuses. The diagnosis of tuberculosis in pilonidal sinus disease is elusive, necessitating a high index of suspicion. The literature on the tubercular affliction of pilonidal sinus is scant. Novel diagnostic modalities such as adenosine deaminase levels and polymerase chain reaction (PCR) can be useful in doubtful situations. Physicians should obtain a thorough history focusing on risk behaviors for human immunodeficiency virus infection (HIV) and tuberculosis. Treatment comprises of standard regimen of antitubercular medication and a modest surgical approach towards the sinuses. PMID:22338544

    2016-01-01

    Cystic fibrosis (CF) is an autosomal recessive genetic disorder caused by mutations in the CF transmembrane conductance regulator gene(CFTR) resulting in impaired ion transport. Nearly all people with CF will develop chronic rhino-sinusitis (CRS) and present with the characteristic viscous mucus, impaired mucociliary clearance and chronic inflammation/infection of the sinonasal cavity. While some individuals with CF can appear relatively asymptomatic in terms of their sinus disease, commonly reported symptoms include anosmia, headache, facial pain, nasal obstruction, chronic congestion and nasal discharge. Nasal endoscopy typically reveals mucosal edema, purulent discharge and nasal polyposis. Computed tomography (CT) imaging classically demonstrates the distinguishing findings of sinus hypoplasia or aplasia with generalized opacification, medial bulging of the lateral sinonasal sidewall and a demineralized uncinate process. Current treatment for CF sinusitis includes the use of hypertonic saline, topical and systemic steroids, antibiotics and endoscopic surgery. Research investigating novel therapies designed at targeting the primary defect of CF is showing promise for reversal of CF sinus disease, in addition to potential for disease prevention.

    Three patients with mucormycosis of the paranasal sinuses were treated in the University ENT departments in Bochum and Essen in recent years. All patients were immunocompromised for different reasons and had reduced resistance against microorganism infection. They presented with symptoms of orbital complications of sinusitis. The further progress of these life-threatening fungal infections with a mortality rate between 35 and 70% depends on early and definitive diagnosis and radical surgical therapy to reduce the amount of infectious agent. The difficulties of early diagnosis by imaging, histology, microbiology, or molecular biology and postoperative therapeutic options especially with amphotericin B, liposomal amphotericin B, and posaconazole are illustrated and 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.

    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

    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 cm(2) 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.

    2016-10-01

    Although functional endoscopic sinus surgery is an effective means of treating patients with recurrent and refractory sinusitis, the procedure is not without risk of serious surgical complications. Preoperative computed tomography (CT) affords radiologists the opportunity to prospectively identify anatomic variants that predispose patients to major surgical complications; however, these critical variants are not consistently evaluated or documented on preoperative imaging reports. The purpose of this review is to illustrate important anatomic variants and landmarks on the preoperative sinus CT with a focus on those that predispose patients to surgical complications. These critical variants and landmarks can be quickly recalled and incorporated into the preoperative imaging report through the use of the mnemonic "CLOSE": Cribriform plate, Lamina papyracea, Onodi cell, Sphenoid sinus pneumatization, and (anterior) Ethmoidal artery. This approach will greatly enhance the value of the preoperative imaging report for referring otolaryngologists and help reduce the risk of surgical complications.

    We report on a 28-year-old man with severe headache. Imaging studies included CT and MR. A large sphenoid mucocoele was demonstrated as well as findings compatible with fibrous dysplasia of the facial bones. Both disorders had been previously unknown. Imaging findings suggested that the sphenoid mucocoele was related to an obstruction caused by the expansile bone of fibrous dysplasia. These findings were confirmed surgically. Fibrous dysplasia with subsequent outflow obstruction is an extremely rare cause of sphenoid mucocoele development.

    PURPOSE Invasive fungal sinusitis (IFS) has rarely been reported to develop from non-IFS. The purpose of this study was to disclose the nature of the extrasinonasal infiltrative process in the presence of a sinonasal fungus ball (FB). METHODS We retrospectively reviewed the medical records, computed tomography, magnetic resonance images of 13 patients with sinonasal FB and the extrasinonasal infiltrative process. Based on histology and clinical course, we divided the extrasinonasal infiltrative process into IFS and the nonfungal inflammatory/infectious process (NFIP). The images were analyzed with particular attention to the presence of cervicofacial tissue infarction (CFTI). RESULTS Of the 13 patients, IFS was confirmed in only one, while the remaining 12 were diagnosed to have presumed NFIP. One patient with IFS died shortly after diagnosis. In contrast, all 12 patients with presumed NFIP, except one, survived during a mean follow-up of 17 months. FB was located in the maxillary sinus (n=4), sphenoid sinus (n=8), and both sinuses (n=1). Bone defect was found in five patients, of whom four had a defect in the sphenoid sinus. Various sites were involved in the extrasinonasal infiltrative process, including the orbit (n=10), intracranial cavity (n=9), and soft tissues of the face and neck (n=7). CFTI was recognized only in one patient with IFS. CONCLUSION In most cases, the extrasinonasal infiltrative process in the presence of sinonasal FB did not seem to be caused by IFS but probably by NFIP. In our study, there were more cases of invasive changes with the sphenoid than with the maxillary FB. PMID:27283592

    Central Nervous System (CNS) infections like meningitis and cerebral abscess caused by Staphylococcus aureus are usually seen in patients with neurosurgical interventions or immune compromised patients or patients with cardiac vegetation's. They are extremely rare in healthy patients. We report a case of a 44 year old Indian gentleman who was perfectly healthy with no known co morbidities, which presented with fever, neck stiffness and altered mental status. He had fulminant staph bacteraemia (as evidenced by persistently positive blood cultures) with meningitis and cerebral abscess. Extensive search was made to find the source of infection, but it was inconclusive. Isolated CNS Methicillin Sensitive Staphylococcus aureus (MSSA) infection in an apparently healthy patient is very rare. This gentleman presented with altered mental status, asymmetrical exophthalmos and multiple cranial nerve palsies. This case highlights the challenge of making early diagnoses of a brain abscess; since it has symptomology mimicking cavernous sinus thrombosis .This is due to the involvement of the cerebellopontine angle and extensive brain oedema and oedema of the retro bulbar tissues.

    A sphenochoanal polyp is a rare lesion that originates in the sphenoid sinus. It occurs most often in adolescents and young adults. We present what to the best of our knowledge is the first reported case of a sphenochoanal polyp associated with concomitant nasal polyps. The patient was a 54-year-old man who presented with bilateral nasal obstruction, possible obstructive sleep apnea, and an altered voice, all of which had likely been caused by the presence of a massive left sphenochoanal polyp and bilateral grade III anterior and posterior ethmoid polyps. Because the patient had dilated cardiomyopathy, he was not a good candidate for general anesthesia. Therefore, the polyps were removed endoscopically under local anesthesia. The sphenochoanal polyp measured 7.5 cm in its greatest dimension and weighed 41 g. The patient remained symptom-free at the 1-year follow-up. The presentation of a sphenochoanal polyp is similar to that of the more common antrochoanal polyp, but the two can usually be differentiated on computed tomography. Endoscopic sinus surgery allows for complete removal of the polyp, including its site of origin, which minimizes the risk of recurrence.

    A case report of a massive cholesterol granuloma (CG) of the frontal sinus in a 15-year-old male subject treated endoscopically is reported. CGs are slowly expanding, cystic lesions that are rarely observed in the frontal sinus. Frontal sinus CGs characteristically present with proptosis, diplopia, and a unilateral painless expanding mass above the orbit. Patients frequently report a history of chronic nasal obstruction or head trauma. Although the pathogenesis is unclear, it is likely multifactorial in etiology. Surgical resection via endoscopic sinus surgery has been gaining popularity because of the minimally invasive approach and lower rates of recurrence. PMID:24612824

    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.

    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

    Disease in the sinus node may cause bradyarrhythmias or tachyarrhythmias. Bradyarrhythmias occur because of impaired automaticity (with or without sinus arrest) or because of sinus node exit block. Reentrant or automatic rhythms may produce tachyarrhythmias. Symptoms and signs of sick sinus syndrome include lightheadedness, palpitation, syncope and peripheral or cerebral emboli. After diagnosis by Holter monitoring, symptomatic patients usually improve with placement of a permanent cardiac pacemaker. PMID:3976454

    Introduction: Frontal sinus mucoceles are the commonest among all paranasal mucoceles. With introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. Case Presentation: We described a lateral frontal sinus mucocele with intra-orbital extension, which was successfully managed by endoscopic sinus surgery. Conclusions: Endoscopic sinus surgery is the treatment of choice in most frontal sinus mucoceles including lateral frontal mucoceles. PMID:25763256

    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

    Petrositis is a rare and severe complication of acute otitis media and mastoiditis. Although the extension of the inflammatory process from the petrous apex to the adjacent Meckel cave can lead to trigeminal pain, an irritation of the trigeminal nerve roots resulting in acute or chronic hyperactivity of masticatory muscles has never been reported. We report here the unusual case of an 86-year-old man who presented with a handicapping myofascial pain and dysfunction syndrome of the right temporal muscle as a heralding manifestation of an unusual form of petrositis. The patient progressively developed a retropharyngeal abscess, a right sphenoid sinusitis, and fatal meningitis. This case demonstrated that (1) myofascial pain and dysfunction syndrome that does not respond to conventional treatments may suggest an unusual etiology and warrant further medical investigations and a detailed medical history and that (2) petrositis can manifest itself with atypical clinical symptoms and radiologic signs.

    Introduction: Craniopharyngiomas treatment has been challenging because of their anatomical location. The endoscopic endonasal (EE) trans-sphenoidal approach is indicated in sellar, supra sellar, selected intraventricular lesions in adults and children. We are reporting our initial experience of 44 patients managed by EE approach. Materials and Methods: This is a retrospective study of 44 craniopharyngiomas. The goal of surgery was gross-total resection in all cases. All patients underwent pre- and post-operative comprehensive ophthalmological and endocrinological evaluation. Lumbar drain at the start of the operation was used in all cases with tumor larger than 3 cm maximum diameter. Binostril technique vascularized nasoseptal flap and multilayer closure of the dural defect were used. Wide sphenoidotomy, posterior ethmoidectomy, tuberculum selle, and planum removal were performed in all cases. Perioperative antibiotic prophylaxis was used for 72 h. Results: There were 44 patients of age ranging from 8 to 65 (mean: 42) years. Diameter of the tumor varied from 3.1 cm to 6.6 cm (average: 4.3 cm). Visual and pituitary dysfunctions were observed in 44 and 33, respectively, before surgery. Vision improvement, gross-total removal, cerebrospinal fluid (CSF) leak and recurrence were observed in 34, 26, four and six patients, respectively. Average follow-up was 19 months. Conclusion: Endoscopic endonasal trans-sphenoidal approach for craniopharyngioma is safe and effective alternative to transcranial approach in selected patients. Although this technique is associated with effective tumor removal and improved visual outcome, CSF leak, and endocrine dysfunctions remain a major challenge. PMID:25767569

    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. Key words: Maxillary sinusitis/etiology, odontogenic, computed tomography, maxillary sinus. PMID:25858084

    An 80-year-old man with a history of en bloc resection of squamous cell carcinoma of the hard palate (T4aN0M0) was performed a lateral-window sinus lift of the edentulous area of the left maxillary molar region to facilitate future placement of dental implants.Two hours after the surgery, the patient complained of sudden malar swelling. Marked swelling was present from the left infraorbital region to the buccal region. The swelling was associated with air pockets at the alar base and in the angulus oculi medialis region and subcutaneous malar tissue. Emphysema appeared after the patient blew his nose. Therefore, the mucous membrane of the maxillary sinus might have had a small hole, and air might have entered the subcutaneous tissue via the bone window when the air pressure in the maxillary sinus increased with nose blowing. It is important to advise patients to avoid increasing the intraoral pressure after sinus-lift procedure. PMID:26088054

    Septic cerebral venous sinus thrombosis, once a common and deadly disease, has fortunately become rare now. Not only that the incidence has fallen significantly after the antibiotic era, the morbidity and mortality has also decreased substantially. Cavernous sinus thrombosis is by far the commonest form of septic cerebral venous sinus thrombosis. Due to its rare occurrence, a lot of current generation clinicians have not encountered the entity in person. Despite all the advances in diagnostic modalities, a high index of clinical suspicion remains the mainstay in prompt diagnosis and management of this potentially lethal condition. Keeping this in view, the authors have reviewed the subject including the old literature and have summarized the current approach to diagnosis and management. Septic cavernous thrombosis is a fulminant disease with dramatic presentation in most cases comprised of fever, periorbital pain and swelling, associated with systemic symptoms and signs. The preceding infection is usually in the central face or paranasal sinuses. The disease rapidly spreads to contralateral side and if remains undiagnosed and untreated can result in severe complications or even death. Prompt diagnosis using radiological imaging in suspected patient, early use of broad spectrum antibiotics, and judicial use of anticoagulation may save the life and prevent disability. Surgery is used only to treat the nidus of infection. PMID:26944152

    Aggressive fibromatosis (AF) is a benign tumour with expansive and locally invasive growth. It is very rarely seen in the head and neck area. We present a 52-year-old female patient with AF localized to the left frontal sinus. The condition was initially mistaken for chronic sinusitis however computed tomography indicated tumour. A biopsy showed AF and the patient received surgical treatment. Symptoms, signs and treatment are discussed. It is concluded that AF in the sino-nasal tract is a rare, but potentially life threatening condition which might be mistaken for a simple sinusitis. PMID:19176167

    Osteomas are the most frequent benign tumors of the paranasal sinuses. They often grow in the frontal sinus near the nasofrontal duct. They remain frequently asymptomatic and they tend to be an incidental finding on radiographic studies. Rarely, they extend out of the sinus limits. Two cases with neuro-ophthalmological complications are reported and discussed. A 19-year-old female presented with a progressive left visual impairment and orbital bone deformity. A CT-scan revealed a large calcified mass in both frontal sinuses, with left intraorbital and frontobasal extension. A 21-year-old man suffered from acute frontoethmoidal sinusitis. Radiological exams revealed a right frontal sinus osteoma with bilateral nasofrontal ducts obstruction. The frontal sinus cavities were filled with a large mucocele with intracranial extension. Both patients were successfully treated using frontobasal craniotomy with complete osteoma and mucocele removal and cranio facial bone reconstruction. Neuro-ophthalmological or intrasinusal complications of osteomas lead to radical treatment. CT-scan and MRI analysis for surgical purpose and strategy are emphased.

    With the advent of functional endoscopic sinus surgery (FESS) and coronal computed tomography (CT) imaging, considerable attention has been directed toward paranasal region anatomy. Detailed knowledge of anatomic variations in paranasal sinus region is critical for surgeons performing endoscopic sinus surgery as well as for the radiologist involved in the preoperative work-up. To be in the known anatomical variants with some accompanying pathologies, directly influence the success of diagnostic and therapeutic management of paranasal sinus diseases. A review of 512 (1024 sides) paranasal sinus tomographic scans was carried out to expose remarkable anatomic variations of this region. We used only coronal sections, but for some cases to clear exact diagnosis, additional axial CT scan, magnetic resonance imaging (MRI) and nasal endoscopy were also performed. In this pictorial essay, rates of remarkable anatomic variations in paranasal region were displayed. The images of some interesting cases were illustrated, such as the Onodi cell in which isolated mucocele caused loss of visual acuity, agger nasi cell, Haller's cell, uncinate bulla, giant superior concha bullosa, inferior concha bullosa, bilateral carotid artery protrusion into sphenoid sinus, maxillary sinus agenesis, bilateral secondary middle turbinate (SMT) and sphenomaxillary plate. The clinical importance of all these variations were discussed under the light of the literature. It was suggested that remarkable anatomic variations of paranasal region and their possible pathologic consequences should be well defined in order to improve success of management strategies, and to avoid potential complications of endoscopic sinus surgery. The radiologist must pay close attention to anatomical variations in the preoperative evaluation.

    Sinus pericranii is a rare vascular anomaly involving an abnormal communication between the extracranial and intracranial circulations. A 3-year-old girl presented with a 2 x 2-cm, midline soft-tissue mass at the vertex. Plain skull films and CT using bone windows showed erosion of the parietal bones. MRI confirmed the clinical diagnosis by identifying communication of the vascular mass with the intracranial dural venous sinus. The advantages of MRI are discussed. PMID:11075608

    In the Department of Oral and Maxillofacial Surgery, patients with trismus can be easily identified. If the cause of trismus is infection of the masticatory space near the pterygoid plexus, the possibility of cavernous sinus thrombosis should be considered. We report the case of a patient who presented with limited mouth opening and progressed to cavernous sinus thrombosis, along with a review of the relevant literature. PMID:25741468

    The authors have evaluated the interest of sphenoidal electrodes in detection of internal temporal spikes, and intra-orbital electrodes in the detection of orbito-frontal spikes. From a study of 26 patients, 21 with sphenoidal electrodes, 3 with intra-orbital electrodes and 2 with both electrodes, they observed the sensitivity and specificity of such electrodes in detecting spikes with no traduction upon extra-cranial electrodes, or with an unsuspected traduction as spikes at a distance from deep electrodes, or spikes on 2 foci, or bisynchronous discharges. Sphenoidal and intra-oribital electrodes constitute a non-invasive method that provides excellent information in the exploration of the mesiobasal cerebral face. Indications for the use of such a method are complex absences without EEG traduction or with an unsuspected traduction and without abnormalities on CT scan, in the context of functional surgery of epilepsy.

    Invasive meningiomas involving the medial sphenoid wing are difficult tumors to resect completely. They often have invaded the surrounding arteries at the time of diagnosis making total resection challenging. Attempts at removing these tumors from adherent carotid or middle cerebral arteries have resulted in high complication rates. Nine cases of medial sphenoid wing meningiomas with arterial invasion were operated between March 1994 and August 1998. Total resection was possible in only four cases. Two arterial-related complications occurred during resection with one resulting in permanent hemiplegia. ImagesFigure 1Figure 2 PMID:17167608

    2009-06-01

    In 1965, Feng of the Peking Union Hospital published an article entitled "Innovation in electroencephalography: the use of acupuncture needles as sphenoidal electrodes". It was a preliminary report, but surprisingly EEG records in the figures did not show definite spikes or sharp waves in the sphenoidal leads. In 1983, Feng and his colleagues reported a summary of 2,000 cases studied with acupuncture needle sphenoidal electrodes. This time, spikes or sharp waves were shown in EEG recordings. However, cases studied were several "paroxysmal disorders", including psychomotor seizure (155 cases), generalized seizure (765 cases), epileptic cephalgia (101 cases), syncope (104 cases), abdominal epilepsy (24 cases), encephalopathy (135 cases), brain tumor (32 cases), hemiplegia of unknown cause (43 cases), psychosis (34 cases), and others (607 cases). Therefore, there were many unknown cases and many cases that were not related to temporal lobe epilepsy. Surprisingly, the increase in detection by acupuncture needle electrode was higher for hemiplegia of unknown cause, brain tumors, and encephalopathies than for the temporal lobe epilepsy. Furthermore, the issue of no insulation of the acupuncture needle was not addressed. Therefore, we began in 1988 to reinvestigate the usefulness of uninsulated acupuncture needles as sphenoidal electrodes. We also compared the efficacy of anterior temporal electrodes (T1, T2) with those of acupuncture needle and EMG needle. Our results showed that when compared to the routine EEG recordings, acupuncture needle sphenoidal electrodes increased the yield of detecting anterior temporal spikes from 41% to 70%. Our data further showed that when compared to the EMG needle recordings, acupuncture needle recordings had the same detection rate, but the spike amplitude was slightly smaller (129 microv vs. 135 microv). Interestingly, we also found that anterior temporal surface electrode recordings were nearly as good as those of acupuncture needle

    A lateral cervical sinus, also known as a second pharyngeal or branchial cleft fistula/sinus, occurs when the second pharyngeal arch fails to grow caudally over the third and fourth arches, leaving remnants of the second branchial clefts in contact with the surface of the neck via a narrow canal. This type of sinus is detected on the lateral aspect of the neck directly anterior to the sternocleidomastoid muscle. We report two pediatric cases with lateral cervical sinus, and pathognomonic sonographic findings to confirm the diagnosis. The first case involved a 3-month-old boy with a sinus on the lateral neck and occasional drainage from a cervical sinus opening. Sonography revealed that the sinus tract extended between the external and internal carotid arteries. In case two, a 1-month-old girl presented with a sinus on the lateral neck and signs of acute infection at the site of a pinpoint opening. Sonography revealed an oval-shaped cystic lesion and sinus tract extending between the external and internal carotid arteries. Sonography does not require radiation or sedation for children. The best choice for the first examination for lateral cervical sinus is sonography, rather than CT, MRI, or contrast fistulograms. PMID:26576989

    Objectives To study the utilization of balloon catheter dilation(BCD) compared to traditional endoscopic surgery(ESS). 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

    2010-03-01

    Prior to the introduction of functional endoscopic sinus surgery, several surgeons had begun to use telescopes to perform surgical procedures in the nose and sinuses. However, the central concepts of functional endoscopic sinus surgery evolved primarily from Messerklinger's endoscopic study of mucociliary clearance and endoscopic detailing of intranasal pathology. The popularity of a combination of endoscopic ethmoidectomy plus opening of secondarily involved sinuses grew rapidly during the latter part of the twentieth century, and endoscopic intranasal techniques began to expand to deal with pathology other than inflammation. We present a review of the evolution of knowledge regarding the pathogenesis of inflammatory sinus disease since that point in time, and of the impact that this has had on the management of inflammatory sinus disease. We also detail the technological advances that have allowed endoscopic intranasal techniques to expand and successfully treat other pathology, including skull base and orbital disease. In addition, we describe evolving technologies which may further influence development within this field. PMID:19930748

    Osteoma is a benign tumor that is composed of compact or cancellous bone. It is the most common benign neoplasm of the paranasal sinus, and ethmoid sinuses are the second most common sites of paranasal sinus osteoma. The symptoms of ethmoid sinus osteoma can give rise to various kinds and extent of symptoms. In symptomatic cases, surgical management is necessary, but appropriate surgical approach to the ethmoid sinus is not clearly established. We describe 2 male patients with a diagnosis of blow-out fractures after trauma; ethmoid sinus osteoma on preoperative computed tomography scans was coincidentally found, and the surgical correction was done simultaneously. The purpose of this article was to present the successful surgical removal of ethmoid osteoma through lamina papyracea and transcaruncular approach, resulting in both successful surgical correction and good cosmetic outcome.

    Context: Maxillary sinusitis is an important issue in dentistry and maxillofacial surgery. This study aims to present a systematic review of etiologies and treatments of odontogenic maxillary sinusitis. Evidence Acquisition: An electronic database search was performed based on related MeSH keywords. Articles published between January 2001 and December 2014 was selected according to the inclusion criteria. The information extracted from various studies was categorized in various tables. Results: The study selected 19 studies. In most studies, oroantral fistula (OAF) was the most common etiology of odontogenic sinusitis. Alpha-hemolytic streptococcus was the most common flora in sinusitis with dental origin. The literature shows that the Caldwell-Luc approach may be the best method for treating sinusitis in cases of displaced teeth. Conclusions: OAF is a common cause of odontogenic maxillary sinusitis and may easily be treated by endoscopy and fistula closure. Maxillofacial surgeons and dentists should consider this problem to avoid misdiagnosis and prevent complications. PMID:26756016

    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

    Non-traumatic intracranial acute epidural hematoma(EDH)is rare. It is mostly caused by coagulation disorders, dural metastasis, or vascular malformations of the dura. We report a case of non-traumatic acute EDH caused by chronic nasal sinusitis and review the literature comprising 10 cases of acute EDH caused by chronic nasal sinusitis. A 16-year-old boy visited our outpatient clinic with a 2-day history of severe headache. He did not have fever or neurological abnormalities and showed no evidence of head trauma. Cranial computed tomography(CT)revealed sphenoid sinusitis and a small amount of epidural air in the middle fossa, but no other intracranial abnormalities. After eight days with no subsequent history of trauma, radiological exams showed a massive acute epidural hematoma in the left middle fossa and temporal convexity without any vascular lesion or skull fracture. The patient underwent a hematoma evacuation that revealed neither a skull fracture nor a vascular abnormality. In this adolescent, chronic nasal sinusitis caused fragility of the meningeal artery wall, an air collection in the epidural space, and the detachment of the dura mater from the inner surface of the skull, thereby resulting in a non-traumatic acute EDH.

    Dermal sinuses have been associated with a wide spectrum of clinical manifestations ranging from asymptomatic to drainage of purulent material from the sinus tract, inclusion tumors, meningitis, and spinal abscess. To date, there has been no documented report of brain abscess as a complication of spinal dermal sinus. Here, we report an 8-month-old girl who was presented initially with a brain abscess at early infancy but lumbar dermal sinus and associated spinal abscess were discovered afterwards. The probable mechanisms of this rare association have been discussed. PMID:19209295

    A causal relationship between sex steroids and meningioma proliferation has long been suspected. We report a case of the clinical progression of a sphenoid wing meningioma after the placement of Norplant, a subcutaneous contraceptive implant containing levonorgestrel, a progesterone agonist. Although not proof of causation, this observation lends further credence to the importance of progesterone receptors in the growth and possible treatment of meningiomas.

    2004-01-01

    ABSTRACT Purpose To determine whether sinus disease may cause acquired strabismus. Methods Patients with idiopathic acquired (nonaccommodative) esotropia and/or hypotropia were questioned in detail about possible contributing factors (trauma; family history of strabismus; thyroid, neurologic, or rheumatologic disorders). Acute versus chronic onset was ascertained. Those without obvious cause of strabismus were investigated for possible sinus disease with sinus computed tomographic scan and otolaryngologic consultation. Results Over a period of 5 years, 59 patients were identified with sinus disease that correlated to their strabismus pattern(s). Twenty-three had “possible” sinus-related strabismus. They had sinus findings that correlated with the strabismus pattern (eg, hypotropia and adjacent maxillary sinus disease). Twenty-six had “likely” sinus-related strabismus. These patients had additional features, such as their own recognition that strabismus worsened along with sinus symptoms, or unusually severe sinus disease. Ten were diagnosed with “very likely” sinus-related strabismus. They had strong correlation between treatment of sinus disease and strabismus improvement. Eighteen patients required sinus surgery owing to failure of medical control. Age at onset of strabismus ranged from 6 months to 81 years. Forty patients required strabismus surgery. All had restriction of motility on forced duction testing under anesthesia. Control of sinus disease combined with range-of-motion eye exercise improved symptoms in 19 who did not require strabismus surgery. Conclusions Occult sinus disease may cause acquired strabismus. Perhaps sinusitis leads to inflammation and secondary contracture in adjacent extraocular muscles. Although difficult to prove owing to the high frequencies of both strabismus and sinus disease, the association between the two may prove significant to strabismus treatment and long-term control.

    Cavernous sinus thrombosis (CST) is a life-threatening entity with a high rate of mortality and lifelong morbidity. A strong clinical suspicion of the complication, early radiological detection and institution of timely, aggressive treatment are required to prevent permanent neurological disability. We present a 12-year-old girl with bilateral CST following unilateral pansinusitis. Clinical symptoms of headache and retro-orbital pain out of proportion to clinical signs on presentation prompted a suspicion of something beyond sinusitis and raised the clinical suspicion of cavernous sinus involvement. In spite of institution of an early medical treatment, she progressed to develop bilateral cranial nerve paresis. However, with the persistence of antibiotics and anticoagulation therapy, she was successfully managed with no residual neurological sequelae. The aim of this presentation is to highlight the grave consequences of cavernous sinus involvement following infections of paranasal sinus and the rare complete recovery from disability in this case.

    Sigmoid sinus diverticulum (SSD) is a rare vascular disorder due to dehiscence of the sigmoid plate. It may be associated with prediverticular venous sinus stenosis (SS) and usually presents as pulsatile tinnitus. The mechanism of development of the SSD and tinnitus from a sinus diverticulum and associated SS is unclear. Previous case reports have suggested that remodeling of the venous system targeting the stenosis, elimination of the diverticulum, or both, have resulted in symptom relief. We present a case of SSD with SS, treated by stenting of the stenosis along with coil embolization of the diverticulum, resulting in complete relief of symptoms. We have also reviewed the literature and discussed the evolution of management from open surgical treatment to endovascular treatment. PMID:27610124

    PubMed Central

    Shenoy, Vijendra; Maller, Vijetha

    2013-01-01

    Introduction. An antrolith is a calcified mass within the maxillary sinus. The origin of the nidus of calcification may be extrinsic (foreign body in sinus) or intrinsic (stagnant mucus and fungal ball). Most antroliths are small and asymptomatic. Larger ones may present as sinusitis with symptoms like pain and discharge. Case Report. We report a case of a 47-year-old lady who presented with heaviness on the left side of the face and loosening of the left 2nd molar tooth since two months. CT scan of the osteomeatal complex and paranasal sinuses showed an opacification of bilateral maxillary sinus and an amorphous area of bone density in the left maxillary sinus. Because of the size of the mass, benign neoplasms were considered in the differential diagnosis. During an endoscopic sinus surgery, it was found to be an antrolith, which was successfully managed by antrostomy and Caldwell-Luc Surgery. Discussion. Antrolith is a rare condition. Rhinoliths are known to invade into the maxillary antrum, but a localised lesion in the antrum is very unusual. A case of an isolated antrolith is presented for its rarity and for differential diagnosis of localised antral disease. Conclusion. Antrolith should be considered as differential diagnosis of unilateral radio-opaque paranasal sinus lesions. PMID:23476856

    2015-01-01

    Objective: To describe clinical characteristics, imaging findings, morbidity, and mortality in a single-center cohort of 12 pediatric cavernous sinus thrombosis cases and to review all cases available in recent English literature. Methods: Clinical data and radiographic studies on 12 cases from our institution were analyzed retrospectively. A literature search and review was conducted, with additional cases pooled with the new cohort for an aggregate analysis. Results: Twelve cases of cavernous sinus thrombosis in children from the Children's Hospital of Philadelphia between January 1, 2000, and December 31, 2013, were reviewed. All patients survived to discharge; 3 of 12 (25%) experienced neurologic morbidity. Contrast-enhanced MRI and contrast-enhanced head CT were 100% sensitive for detecting cavernous sinus thrombosis, while noncontrast time-of-flight magnetic resonance venography (TOF MRV) and noncontrast head CT were 0% sensitive. Literature review produced an additional 40 cases, and the aggregate mortality rate was 4 of 52 (8%) and morbidity rate was 10 of 40 (25%). Outcomes did not vary by treatment or with unilateral vs bilateral cavernous sinus involvement. There was a trend toward worse outcomes with fungal infections. Conclusion: Our case series demonstrates low morbidity and mortality with early, aggressive surgical, antimicrobial, and anticoagulation therapies. Although anticoagulation and surgery were not associated with significantly different outcomes, more study is needed. PMID:26231260

    2015-01-01

    Mucocoeles are chronic mucosa-lined retention cysts that occur due to sinus ostium obstruction and expand along the path of least resistance, most commonly involving the frontal sinus. A frontal mucocoele typically appears as a smooth and rounded expansile enlargement of a completely opacified frontal sinus, with or without thinning of the bony wall of the sinus. Here we report a rare case of isolated intracranial mucocoele that presented with posterior herniation to the anterior cranial fossa through a small bony defect on the posterior table of the frontal sinus. The findings upon imaging could easily be confused with intracranial abscess, potentially leading to craniotomy drainage. In the present case of mucocoele, the frontal intracranial lesion was completely resolved following endoscopic frontal sinusotomy.

    The objective of the present publication was to report the result of the evaluation of the clinical effectiveness of azithromycin (Sumamed) antimicrobial therapy used for the treatment of bacterial acute rhinsinusitis (ARS) in the patients presenting with concomitant pathology of the respiratory and cardiovascular systems. Dynamics of the reversal of the clinical symptoms of bacterial ARS in the patients of the study group is described. Neither adverse side effects nor complications in response to the treatment were documented. 98.6% of the patients recovered from the disease within 7 days after the onset of the treatment. It is concluded that antimicrobial therapy with the use of azithromycin (Sumamed) based at the outpatient settings provides a highly efficient tool for the treatment of the patients presenting with concomitant pathology of the respiratory and cardiovascular systems.

    Classical homocystinuria is the most commonly inherited disorder of sulfur metabolism, caused by the genetic alterations in human cystathionine beta-synthase (CBS) gene. In this study, we present comprehensive clinical findings and the genetic basis of homocystinuria in a cohort of Turkish patients. Excluding some CBS mutations, detailed genotype-phenotype correlation for different CBS mutations has not been established in literature. We aimed to make clinical subgroups according to main clinical symptoms and discussed these data together with mutational analysis results from our patients. Totally, 16 different mutations were identified; twelve of which had already been reported, and four are novel (p.N93Y, p.L251P, p.D281V and c.829-2A>T). The probands were classified into three major groups according to the clinical symptoms caused by these mutations. A psychomotor delay was the most common diagnostic symptom (n=12, 46.2% neurological presentation), followed by thromboembolic events (n=6, 23.1% vascular presentation) and lens ectopia, myopia or marfanoid features (n=5, 19.2% connective tissue presentation). Pyridoxine responsiveness was 7.7%; however, with partial responsive probands, the ratio was 53.9%. In addition, five thrombophilic nucleotide changes including MTHFR c.677 C>T and c.1298 A>C, Factor V c.1691 G>A, Factor II c.20210 G>A, and SERPINE1 4G/5G were investigated to assess their contributions to the clinical spectrum. We suggest that the effect of these polymorphisms on clinical phenotype of CBS is not very clear since the distribution of thrombophilic polymorphisms does not differ among specific groups. This study provides molecular findings of 26 Turkish probands with homocystinuria and discusses the clinical presentations and putative effects of the CBS mutations. PMID:24211323

    Pleomorphic adenoma is the most common benign tumour of the salivary glands, especially the parotid gland. In the present paper we introduce the rare case of a pleomorphic adenoma of the maxillary sinus in a 82-year-old man who was referred to our outpatient clinic with nasal obstruction and occasional events of nose bleeding. Thorough investigation, using endoscopy and computed tomography, revealed a mass extending from the left maxillary sinus to the nasal cavity; the tumour was removed surgically; pathological examination showed a pleomorphic adenoma with no signs of malignancy.

    Maxillary sinus inflammation, when untreated or incorrectly treated, may extend locoregionally, the remaining paranasal sinuses being the first affected anatomical structures. This is why the understanding of the inflammatory pathology of the maxillary sinus, and particularly of the complications it can generate, is extremely important. The purpose of this presentation is to point out that inflammations of the paranasal sinuses are susceptible to develop complications in certain conditions and threaten the patient's life due to the proximity of vital structures. This is the case of a 16 years old male patient who developed a left maxillary and frontal sinusitis, complicated with cerebral abscess. Early detection, multidisciplinary approach and proper indication of surgical treatment, as well as early suspicion of complication, especially in young male adolescents, are extremely important.

    Inverted papilloma is a benign locally aggressive tumor of paranasal sinuses which has been traditionally managed with external surgical approaches. Advances in tumor imaging, surgical instrumentation and intraoperative visualization have led to a gradual shift to endonasal attachment-oriented surgery. Involvement of both frontal sinuses by inverted papilloma is rare. There are scant reports in the literature regarding this topic. We present 2 cases of the tumor involving both frontal sinuses removed by median drainage (Draf III procedure) under endoscopic guidance without any additional external approach. The whole cavity of both frontal sinuses was easily inspected at the end of the procedure. No early or late complications were observed. No recurrence was seen in 1-year or 2-year follow-up. Management of frontal sinus inverted papilloma with the endoscopic median drainage approach is feasible and seems to be effective. PMID:23362431

    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.

    Dental implant associated rehabilitation of the posterior maxilla poses unique challenge owing to the presence of pneumatized sinuses and atrophied alveolar bone. Sinus augmentation procedure to manage expanded sinuses frequently results in membrane tear resulting in unfavorable stabilization of the graft and associated bone regeneration. Simultaneous implant placement during sinus augmentation procedures frequently requires a minimal alveolar bone height, which when not present forces clinician to defer implant placement resulting in extended treatment duration and multiple surgical appointments. The present case report is about a piezosurgery assisted lateral wall osteotomy approach for sinus augmentation associated with membrane repair with simultaneous implant placement in the posterior maxilla.

    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.

    Variations in intracranial dural venous sinus anatomy have been widely reported in humans, but there have been no studies reporting this in dogs. The purpose of this retrospective study was to describe variations in magnetic resonance (MR) venographic anatomy of the dorsal dural venous sinus system in a sample population of dogs with structurally normal brains. Medical records were searched for dogs with complete phase contrast, intracranial MR venograms and a diagnosis of idiopathic epilepsy. Magnetic resonance venograms were retrieved for each dog and characteristics of the dorsal dural sinuses, symmetry of the transverse sinuses and other anatomic variations were recorded. A total of 51 dogs were included. Transverse sinus asymmetry was present in 58.8% of the dogs, with transverse sinus hypoplasia seen in 39.2%, and aplasia in 23.5% of dogs. For 70.6% of dogs, at least one anatomic variation in the dorsal sagittal sinus was observed, including deviation from the midline (33.3%) and collateral branches from either the dorsal sagittal sinus or dorsal cerebral veins (54.9%). In 5 dogs (9.8%) a vessel was also identified running from the proximal transverse sinus to the distal sigmoid sinus, in a similar location to the occipital sinus previously reported in children. Findings from this study indicated that, as in humans, anatomic variations are common in the intracranial dural venous sinus system of dogs. These anatomic variations should be taken into consideration for surgical planning or diagnosis of cerebrovascular disease.

    Osteomas are the most common fibro-osseous lesions in the paranasal sinus. They are benign tumours characterized by slow growth and are often asymptomatic. Treatment is indicated in sphenoid osteomas that threaten the optic canal or orbital apex and in symptomatic cases. The choice of surgical management depends on the location, size and experience of the surgeon. An open approach allows tumour removal with direct visual control and remains the best option in large tumours, but the continued progression in endoscopic approaches is responsible for new indications in closed techniques. Immediate reconstruction allows aesthetic and functional restoration of neighbouring structures, which should one of the goals in the treatment of this benign entity. We report a case of a giant ethmoid osteoma with orbital invasion treated by a combined open craniofacial approach with reconstruction of the anterior cranial base and orbital walls. The literature is reviewed and aetiopathogenic theories, diagnostic procedures and surgical approaches are discussed.

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.

    Background: Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. Case Report: Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery and excision of the osteoma by the Caldwell-Luc procedure. Conclusion: Unique coexistence of two different entities in the maxillary sinus is most likely due to pediatric facial trauma. Pediatric patients with maxillofacial trauma should be carefully watched for dental injury both clinically and radiologically.

    The study of the venous channels in the cavernous sinus in 48 sphenoid bones was performed. Thirty-eight bones were electrolyticly decalcified, subsequently embedded in gelatin, and cut in 1 mm thick slices. Microdissection of the other ten specimens complemented the analysis. Every specimen had the venous structure arranged as a plexus, however, although the channels were variable in number, form, and diameter, the two sides were quite symmetrical. Channels of smaller diameter predominated anteriorly. There was no demonstrable muscular layer in these vessels; the endothelial lining was easily visualized. Fatty tissue separated the venous channels from each other and from arteries and nerves. The distance from the carotid artery and the lateral wall increased anteriorly, but there were significant veins between these two structures in only 35% of the cases. In about one third of specimens the oculomotor nerve was placed over the carotid artery. The abducens nerve was found to be intimately related to the lateral wall without any venous channels between them in 92% of the specimens.

    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.

Several studies have demonstrated the safety, efficacy, and ease of use of this new technique. To provide support and coordinate the surgical process in powered functional endoscopic sinus surgery procedures, perioperative nurses must have an appreciation for its specific equipment handling and for appropriate patient care. This article describes a specific protocol that perioperative nurses can use to facilitate efficient and safe surgical environments for patients who undergo powered endoscopic sinus surgery procedures.

    2010-09-01

    A mucocele is a mucus-containing sac lined with epithelium that arises within a sinus when its drainage is compromised. The frontal sinus is the most common location, with frontal mucocele development occurring when the nasofrontal duct becomes obstructed because of polyps, bone tumors, prior surgery, sinusitis, trauma, or anatomic variation. We report an unusual case of a sterile pediatric frontal mucocele presenting as a slowly enlarging forehead mass due to a bifid frontal sinus septum. A 9-year-old girl presented to the craniofacial clinic for evaluation of a right frontal mass that had been slowly growing over the past year. She was otherwise healthy and had no history of previous trauma or sinus infections. Computed tomography (CT) scan results revealed a localized frontal fluid collection with protrusion and thinning of the anterior frontal bone between 2 midline bony septii. Surgical cranialization of the frontal sinus was performed. The anatomy of her lesion seen both on CT scan and intraoperatively likely explains this unusual case presentation. Instead of the usual inciting event of an intact frontal sinus drainage system becoming blocked, this patient seemed to have a primary developmental lack of any drainage system that led to her mucocele. During formation of her frontal sinus, she developed a bifid septum within the midline that excluded a portion of her frontal sinus from the lateral nasofrontal ducts. With mucus-producing epithelium trapped within these bony confines, pressure began to mount with expansion and thinning of the bone both anteriorly and posteriorly. The lack of any infectious symptoms and sterile culture results may support that this space developed primarily and was never in continuity with the external drainage system. Only 4 other patients have been reported with asymptomatic forehead swelling as the only presenting symptom, with the age ranging from 33 to 79 years. This patient represents the first clinical report of a congenital

    Sinus histiocytosis with massive lymphadenopathy (SHML) is a newly recognized, distinct, pseudolymphomatous benign entity with very characteristic microscopic features. Most patients are children or young adults with massive painless cervical adenopathy, although other node groups and extranodal sites often are involved. Sixteen patients with SHML involving the upper respiratory tract and/ or salivary gland are presented. Nine of the patients had ear, nose, and throat (ENT) manifestations at the time of presentation. In most cases the ENT involvement resulted in prominent clinical symptoms. Treatment included surgery, antibiotics, irradiation, chemotherapy, and steroids, frequently in combination, but no consistent pattern of response emerged from the study. These 16 patients were very similar clinically to patients with SHML who did not have ENT disease, indicating that extranodal involvement is not associated with more aggressive disease.

    Meningioma is a well-recognized tumor of the central nervous system, but it rarely appears as a primary extracranial tumor of the paranasal sinuses. We report a case of a primary right anterior ethmoid meningioma that resembled a mucocele in its presentation. A primary meningioma can be differentiated from a secondary meningioma in three ways: (1) by observing an intact bony wall of the sinus on imaging or on inspection during surgery, (2) by noting the absence of a simultaneous intracranial meningioma on imaging or on inspection during surgery, and (3) by identifying a bulging of the sinus wall toward the cranium rather than in the opposite direction.

    Acute invasive fungal sinusitis is the most aggressive form of fungal sinusitis and can be fatal, especially in patients who are immunosuppressed. Early diagnosis and intervention are crucial and potentially lifesaving, so primary care providers must maintain a high index of suspicion for this disease. Patients may need to be admitted to the hospital for IV antifungal therapy and surgical debridement.

    The valves in the venous system are surrounded by a thinner but expandable vein section that forms a pocket region known as the sinus. The exact function of the sinus pocket for the venous valves is not fully understood. This is especially an issue for the bioprostheticvalve, since most of the prosthetic valves do not have a sinus pocket. To determine the impact of the sinus pocket on the flow dynamics to a prosthetic valve, an in-vitro experiment was setup at normal physiological flow conditions to simulate the flow inside a venous system. Two different valve designs were tested in glass tubes simulating the vein vessel with and without the sinus pocket profile using 2-D particle image velocimetry (PIV). Velocity measurements were made, and vorticity and flow shear were calculated. The results show that vortex structures near the valve leaflet tip were preserved better with the sinus present. The jet width at valve exit was found to be narrower with sinus than without sinus, and the effect was more significant with longer leaflet length. The results suggest that the sinus pocket alters the flow around the valve and functions as a flow regulator. For prosthetic valve without sinus, a shorter leaflet would provide similar effect of sinus and thus is more preferable.

    Patients with episodic sinus tachycardia and associated orthostatic intolerance present a diagnostic and management dilemma to the clinician. We define this group of disorders to include sinus node reentrant tachycardia (SNRT), inappropriate sinus tachycardia (IAST), and postural orthostatic tachycardia syndrome (POTS). After a brief review of the current understanding of the pathophysiology and epidemiology of this group of disorders, we focus on the diagnosis and management of IAST and POTS. Our approach attempts to recognize the considerable overlap in pathophysiology and clinical presentation between these two heterogeneous conditions. Thus, we focus on a mechanism-based workup and therapeutic approach. Sinus tachycardia related to identifiable causes should first be ruled out in these patients. Next, a basic cardiovascular and autonomic workup is suggested to exclude structural heart disease, identify a putative diagnosis, and guide therapy. We review both nonpharmacologic and pharmacologic therapy, with a focus on recent advances. Larger randomized control trials and further mechanistic studies will help refine management in the future.

    A 15-year-old Belgian gelding presented in respiratory distress, with bilateral mucopurulent nasal discharge, and right-sided epistaxis. The horse had a 5-year history of dental disease and had been recently losing weight. Radiographs indicated tooth root abscessation of the right maxillary third molar tooth and probable maxillary sinus feed impaction. These findings were confirmed at surgery and necropsy. The stippled, granular radiographic appearance described here is highly characteristic of sinus feed impaction. PMID:24371923

  18. Diagnostic value of 2D and 3D imaging in odontogenic maxillary sinusitis: a review of literature.

    PubMed

    Shahbazian, M; Jacobs, R

    2012-04-01

    This review aims to explore whether 3D imaging offers an added value in diagnosis of odontogenic sinusitis. Odontogenic maxillary sinusitis accounts for approximately 10-12% of maxillary sinusitis cases. Proper diagnosis of odontogenic sinusitis is based on a thorough dental and medical examination and crucial to ensure therapeutic efficacy. To establish the odontogenic cause of maxillary sinusitis, 2D and 3D imaging modalities may be considered, each presenting distinct advantages and drawbacks. The available research indicates that 2D imaging modalities may often mask the origin of odontogenic maxillary sinusitis. This limitation is particularly evident in the maxillary molar region, stressing the need for 3D cross-sectional imaging. The advent of low-dose cone beam computed tomography in dentistry may be particularly useful when odontogenic maxillary sinusitis is not responsive to therapy. Yet, it seems that more research is needed to validate its use in odontogenic maxillary sinusitis.

    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

    Cerebral venous sinus thrombosis is a rare form of stroke caused by thrombosis in venous sinuses of the brain. In this study, we reported on a patient with venous sinus thrombosis and brucellosis who presented with uncontrolled seizure despite being treated with anti-epileptic drugs at high doses. The case was a 33-year-old woman with a history of controlled complex partial seizure who presented with headache, asthenia, and uncontrolled seizure for one month. She was febrile and a brain CT scan indicated hemorrhagic focus in the left posterior parietal and the temporal lobe. Magnetic resonance imaging and magnetic resonance venography also proved venous sinus thrombosis in the left transverse sinus. Besides [In addition], a laboratory assessment confirmed brucellosis. Following the treatment with anti-coagulant, anti-brucellosis, and anti-epileptic agents, the patient was discharged in good condition with medical orders. Clinical suspicion and accurate evaluation of a patient's history is the most important clue in diagnosis and treatment of brucellosis and cerebral venous sinus thrombosis, especially in uncontrolled seizure in patients who had previously been under control.

    Endoscopic sinus surgery can result in both minor and major complications. Among these, orbital complications--including retroorbital hematoma--are among the most feared. Injuries can be direct or indirect from pulling on diseased structures. A retrospective chart review of 616 endoscopic sinus procedures revealed eight orbital complications in seven patients. These included two medial rectus injuries, five orbital hemorrhages, and one nasolacrimal duct injury. Predisposing factors may include hypertension, lamina papyracia dehiscences, extensive polypoid disease, previous surgery, inability to visualize the maxillary ostia, violent coughing or sneezing, and chronic steroid use. Suggested management in the literature includes lateral canthotomy, steroids, and mannitol with ophthalmologic consultation. Opening of the wound by means of an external ethmoidectomy incision has also been suggested. We suggest that adding orbital decompression by means of multiple incisions into the periorbita should be added for fully effective relief. A "management" tree of decision parameters relevant to orbital complications is presented.

Clinical reports on its association with onychomycosis, corneal ulcer and phaeohyphomycosis are available. However, Lasiodiplodia theobromae causing fungal sinusitis has not been reported. We present here a case of fungal sinusitis in a 30-year-old woman, who came to the ENT OPD (out patient department) with complaints of intermittent bleeding and nasal discharge from the left side for a week. The patient complained of headache, predominantly on the left side and heaviness on and off since two months.

    Sinus tarsi syndrome, described by O'Connor in 1958 and Brown in 1960, is a clinical finding often seen after an accident, consisting of a painful reaction to pressure on the sinus tarsi. This syndrome has also been described in dancers, volleyball and basketball players, overweight individuals, and patients with foot deformities (flatfoot). We looked for mechanical and functional macroscopic structures in the canalis and sinus tarsi that can be associated with sinus tarsi syndrome in order to deduce therapeutic consequences. We found a complex fibrous layer in the sinus and canalis tarsi that forms slips around the synovial sheats of the extensor tendons under the inferior extensor retinaculum. Both limbs run deep to the base of the sinus and canalis tarsi. The lateral band inserts into the sinus tarsi at the calcaneus, while the medial band inserts at the canalis tarsi at the talus and calcaneus. Instead of the term "interosseous ligaments," we recommend referring to the "fundiform ligament" with one lateral and one medial band. Regarding function, one can assume that the medial band of these fundiform ligaments controls the talus at eversion and inversion together with the well-vasculated and well-innervated interarticular fat pads in the sinus and canalis tarsi. While contracting the long extensor muscles of the toes, the ligament forms a control mechanism for the longitudinal arch of the foot in the moving phase.A question is how variations in vascularization or disorders in innervation will alter the turgor of the pads of fat tissue. That is, such alterations would influence the distribution of synovia in the neighboring joints as well as the tension of the involved ligaments.

    Silent sinus syndrome (SSS) is a quite rare clinical entity characterized by unilateral enophthalmos and hypoglobus secondary to thinning and inward bowing of the maxillary sinus roof in the absence of signs or symptoms of intrinsic sinonasal inflammatory disease. We present a case of a 16-year-old female with a 10-month history of facial asymmetry due to swelling of the left cheek and ptosis of the left eye with no other symptoms. Computed tomography scans and Water's x-ray revealed an opacified left maxillary antrum with characteristic features of SSS. The patient underwent surgery and a thick maxillary sinus mucocele was found and enucleated successfully during the operation. Six-month and 2-year follow-ups after surgical treatment revealed satisfactory results and there was no need for reconstruction of the orbital floor. Although patients with SSS often initially present to ophthalmologists, oral and maxillofacial surgeons and radiologists should be familiar with this phenomenon since most of these patients will be referred to dental hospitals for further treatment.

  14. Frontal Sinus Fractures: Current Concepts

    PubMed Central

    Strong, E. Bradley

    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

    Introduction: Ectopic tooth eruption may result owing to one of 3 processes: developmentalDisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. In rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. When the maxillary sinus is invaded, symptoms usually occur late in the process. Case Report: A 17 years old boy referred to department of Otolaryngology, Head and Neck Surgery of university of medical sciences, Tabriz_Iran in 2010 with chronic recurrent mucoprulent discharge from retromollar trigone , posterior to right superior alveolar ridge. CT scan revealed a dense mass resembling tooth, obstructing sinus ostium with homogenous opacity with ring enhancement, occupying whole sinus and expanding all walls. A Caldwell Luke approach in combination with endoscopy was selected. Conclusion: In the present patient, removal of ectopic tooth resolved the symptoms completely, the fistula obstructed and discharges discontinued. An ectopic tooth is a rare entity obstructing sinus ostium. The etiology of ectopic eruption has not yet been completely clarified, but many theories have been suggested,including trauma, infection, developmental anomalies and pathologic conditions, such as dentigerous cysts. In summary, although the ectopic teeth is rare but it would be assumed in presence of unilateral symptoms of sinonasal cavity. Therefore in peristant unilateral sinonasal symptoms we should complete examining of this site to rule out rare causes of these symptoms. PMID:24303440

    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.

    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.

    Meningiomas frequently invade cerebral venus sinuses, especially parasagittal meningioma to superior sagittal sinus. However, most invasions do not reach internal jugular vein. We present a case of parasagittal meningioma extending into the internal jugular vein through the sinuses. Radiological investigation revealed that the tumor was invading the sagittal, transverse, sigmoid sinus and junction of the internal jugular vein to subclavian vein, which was filled with tumor. The histopathological examinations revealed that both the cerebral tumor and mass in the internal jugular vein contributed to the transitional meningioma. This is a rare case of a meningioma extending into the internal jugular vein through the sinuses. According to this case, the frontal parasagittal meningioma could invade directly the internal jugular vein. The significance of this association to cerebral venus sinuses and internal jugular vein are discussed. PMID:19096607

    Invasive Aspergillus (IA) sinusitis is a life-threatening opportunistic infection in immunocompromised individuals, but it is uncommon in human immunodeficiency virus (HIV) infection. 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.

    Digoxin, in a common clinical dose and at a low serum level, brought out severe manifestations of sinus node dysfunction in a patient who had previously undergone successful mitral valve replacement. This report presents the results of extensive clinical and electrophysiologic studies of this patient before and after a digoxin challenge. In the absence of cardiac glycoside, the only demonstrable abnormalities of sinus node function were mild resting sinus bradycardia and failure to respond to atropine administration. Responses to isoproterenol administration, programmed premature atrial stimulation, and overdrive pacing at several cycle lengths were normal. Following the administration of intravenous digoxin, 1.025 mg/24 hrs, the resting sinus cycle length increased and the response to overdrive pacing became markedly abnormal. The latter was followed by sinus pauses in excess of six seconds, even at relatively slow overdrive pacing rates. The electrophysiologic and clinical implications of these data are discussed. It is suggested that despite previous reports that digitalis preparations are relatively well tolerated by patients with sick sinus syndrome, caution should be used when administering these drugs to this group of patients.

    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.

    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 visual outcome of 22 patients undergoing trans-sphenoidal excision of pituitary macroadenomas with intraoperative flash visual evoked potential (VEP) monitoring (Group A), was compared with a non-randomized group of 14 patients who had undergone similar operations without VEP monitoring (Group B). Tumour size, preoperative visual acuity, peripheral fields, and latencies and amplitudes of P1 and P2 were analysed to ascertain the best predictor of postoperative visual function. It was found that patients in Group A had a significantly greater improvement in field defects than those in Group B. There was no difference in postoperative improvement in visual acuity between the two groups. None of the variables analysed were good predictors of visual outcome.

    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

    Sick sinus syndrome refers to a collection of disorders marked by the heart's inability to perform its pacemaking function. Predominantly affecting older adults, sick sinus syndrome comprises various arrhythmias, including bradyarrhythmias with or without accompanying tachyarrhythmias. At least 50 percent of patients with sick sinus syndrome develop alternating bradycardia and tachycardia, also known as tachy-brady syndrome. Sick sinus syndrome results from intrinsic causes, or may be exacerbated or mimicked by extrinsic factors. Intrinsic causes include degenerative fibrosis, ion channel dysfunction, and remodeling of the sinoatrial node. Extrinsic factors can be pharmacologic, metabolic, or autonomic. Signs and symptoms are often subtle early on and become more obvious as the disease progresses. They are commonly related to end-organ hypoperfusion. Cerebral hypoperfusion is most common, with syncope or near-fainting occurring in about one-half of patients. Diagnosis may be challenging, and is ultimately made by electrocardiographic identification of the arrhythmia in conjunction with the presence of symptoms. If electrocardiography does not yield a diagnosis, inpatient telemetry monitoring, outpatient Holter monitoring, event monitoring, or loop monitoring may be used. Electrophysiologic studies also may be used but are not routinely needed. Treatment of sick sinus syndrome includes removing extrinsic factors, when possible, and pacemaker placement. Pacemakers do not reduce mortality, but they can decrease symptoms and improve quality of life.

    Introduction: Sinus tract is one of the manifestations of chronic dental infections, which is a path for the drainage of the infection and pus. The present study was aimed to investigate the prevalence of sinus tract with dental origin analyze the correlation between sinus tract and related factors. Methods: This study was conducted on 1527 patients, visiting Kermanshah school of dentistry, in 2014.The related teeth were examined in terms of vitality test and exact location of sinus tract. Moreover, the causes of this lesion and the needs for root canal treatment were assessed in these teeth. Having obtained the data from the patients, analyzed by Mann-Whitney, Chi-square tests. Results: The frequency of sinus tract was 9.89% patients. There was a significant correlation between the prevalence of sinus tract and factors such as age, general health status, location of sinus tract and history of root canal treatment. The prevalence of sinus tract in maxilla was higher than the mandible (p=0.087). The prevalence of sinus tract in the posterior teeth (69.54%) was significantly higher than that of anterior teeth (30.46%) (p=0.000). From 724 teeth with periapical inflammation and radiolucency, 9.89% teeth had odontogenic sinus tract, and 23.42% teeth with history of root canal treatment had sinus tract. Conclusions: The most common cause of sinus tract incidence was previous root canal treatment. Therefore, clinicians need to pay a more attention to examining the posterior teeth referred for endodontic treatment. PMID:26153170

  9. 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.

    The sinuses are common sites of infection in children, and if clinical presentation is delayed, there is a high risk of complications including intracranial spread. We present a case of a 5-year-old boy who presented with non-specific symptoms of sinusitis. He went on to develop osteomyelitis of the frontal bone and a subperiosteal abscess known as Pott's puffy tumour. Whilst computed tomography provides an excellent initial imaging, this case report emphasizes the advantages of magnetic resonance imaging, especially when there is extensive involvement of the sinuses with an absence of ionizing radiation. Prompt surgical treatment is imperative as there is a potential for significant morbidity if not quickly diagnosed and treated. PMID:27001196

    2015-12-01

    Endoscopic sinus surgery (ESS) is the mainstay of the treatment in sinus disorders, to re-establish the drainage of the affected sinus. The close proximity of the orbital structures to paranasal sinuses makes them vulnerable to inadvertent injury during the sinus surgery. Medial rectus (MR) muscle is the most commonly injured extraocular muscle during ESS due to its anatomic proximity to the thin medial wall of the orbit. This is a non-comparative, retrospective, interventional case series of six patients presenting with MR injury after ESS. We discuss the management, outcome and review the published literature. A total of six patients met the inclusion criteria. The presenting complaints were diplopia, squinting and limitation of ocular movements. Two patients underwent surgical exploration of the MR muscle and reattachment of the muscle along with injection botulinum to the antagonist lateral rectus muscle. Two patients who had small angle strabismus and who were able to fuse were advised orthoptic exercises and prisms as management. Remaining two patients were advised surgical intervention to correct strabismus but they declined further surgical intervention. Management of MR injury following ESS is complex, often resulting in suboptimal outcomes. Since early intervention is associated with better outcomes, early referral by otolaryngologists to ophthalmologists would result in better outcome. PMID:26693458

    Background: Spinal dorsal dermal sinus is a rare entity, which usually comes to clinical attention by cutaneous abnormalities, neurologic deficit, and/or infection. The present study was undertaken to know the clinical profile of these patients, to study associated anomalies and to assess the results of surgical intervention. Methods: Medical records of 21 patients treated for spinal dorsal dermal sinus from September 2007 to December 2013 were reviewed. Results: We had 21 patients with male: female ratio of 13:8. Only 2 patients were below 1-year of age, and most cases (15) were between 2 and 15 years (mean age = 8.2 years). Lumbar region (11 cases) was most frequently involved, followed by thoracic (4 cases), lumbosacral, and cervical region in 3 patients each. All of our patients presented with neurological deficits. Three patients were admitted with acute meningitis with acute onset paraplegia and had intraspinal abscess. The motor, sensory, and autonomic deficits were seen in 14, 6, and 8 patients, respectively. Scoliosis and congenital talipes equinovarus were the common associated anomalies. All patients underwent surgical exploration and repair of dysraphic state and excision of the sinus. Overall, 20 patients improved or neurological status stabilized and only 1 patient deteriorated. Postoperative wound infection was seen in 2 cases. Conclusions: All patients with spinal dorsal dermal sinuses should be offered aggressive surgical treatment in the form of total excision of sinus tract and correction of spinal malformation, as soon as diagnosed.

    Frontal sinus fractures (FSF) are relatively uncommon maxillofacial injuries. The most common cause of FSF is motor vehicle accidents with 62% percentage. Management of FSF depends on type of fracture, associated injuries, and involvement of naso-frontal duct. In this report, the authors presented a patient with comminuted fracture of anterior wall of frontal sinus reconstructed with titanium mesh. A 40-year-old man presented with depression of the frontal bone, facial pain, and epistaxis consisting of a motor vehicle accident. Computerized tomography scan revealed multiple comminuted fractures of anterior wall of frontal sinus and fractures of left orbital medial and superior walls. Titanium mesh was used for reconstruction. Postoperative course was uneventful. The titanium mesh, which is easy to handle with no complications, may provide excellent frontal contour after comminuted anterior wall fractures. PMID:26872283

    Septic cavernous sinus thrombosis, a relatively uncommon disease entity, frequently can be fatal. Early diagnosis is imperative in order that appropriate treatment be instituted. A 59-year-old woman who was admitted to our institution with complaints of diplopia, blurred vision and fevers that developed following a tooth extraction is presented. Initial CT and lumbar puncture on the day of admission were totally normal. A repeat CT performed 48 hours after admission, on the same day as gallium imaging, demonstrated findings consistent with cavernous sinus thrombosis. Gallium imaging demonstrated intense uptake in the left cavernous sinus and left orbit as well as moderately increased activity in the right cavernous sinus and orbit, confirming infection. The patient was treated with antibiotics, and repeat CT and gallium imaging were performed ten days later, both of which demonstrated near total resolution of the disease process. Conceivably, if gallium imaging had been initiated on the day of admission it may have been the first study to demonstrate an infectious process in the cavernous sinus. Gallium imaging should be considered as a diagnostic tool in the noninvasive workup of this entity.

    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

    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.

    We report herein on 5 patients with odontogenic maxillary sinusitis caused by a dental restoration (caries cutting, cavity preparation, inlay restoration). Odontogenic maxillary sinusitis was noted following dental restoration. Even though the pulp cavity and dental pulp were intact, the odontogenic maxillary sinusitis occurred caused by an apical lesion. Infection by way of the dentinal tubules was suggested to be a cause of the pathophysiology. Endoscopic sinus surgery was indicated in patients with intractable odontogenic maxillary sinusitis caused by the dental restoration. Cone-beam x-ray CT was useful for the accurate diagnosis of odontogenic maxillary sinusitis caused by a dental restoration. Physicians should thus be aware of the possibility that a tooth, which has undergone dental restoration, may cause odontogenic maxillary sinusitis.

    Osteomas are the most commonly encountered neoplasms of the frontal sinus. Extension of these lesions through the posterior table can result in life-threatening complications. We present the case of a 70-year-old man with yellow nail syndrome who complained of persistent rhinorrhea and the sensation of "sloshing" when moving his head. Radiographic investigation revealed a frontal mucocele that had extended to a dramatic intracerebral pneumatocele. This occurred secondary to a frontal sinus osteoma that had been incidentally noted seven years earlier. Surgical exploration via an osteoplastic flap approach allowed us to excise both the osteoma and the associated pneumatomucocele. The resulting dural defect was resurfaced using a flap of pericranium to facilitate anterior cranialization. The features of this interesting case are discussed as an illustration of the potential complications of frontal sinus osteomas. The literature is reviewed regarding management of these lesions and their complications.

    Flavimonas oryzihabitans is rarely reported as a pathogen in human infections and is related to opportunistic infection. Previously reported cases of infections caused by this bacterium were nosocomially acquired, including bacteraemia in critically ill patients, catheter-related infection, and peritonitis in patients undergoing continuous ambulatory peritoneal dialysis. Three cases of F. oryzihabitans infection are presented, 1 of which was sinusitis and 2 were nosocomially acquired bacteraemia. To the authors' knowledge, this is the first reported case of sinusitis infection due to F. oryzihabitans induced by prosthetic material. Isolates from the 2 bacteraemic patients were susceptible to tazobactam, ceftazidime, cefepime, aztreonam, gentamicin, amikacin, imipenem, ciprofloxacin and levofloxacin, but resistant to cephazolin, cefuroxime and trimethoprim. The isolate from the sinus was susceptible to gentamicin, amikacin, tetracycline, ciprofloxacin and levofloxacin. After appropriate treatment all the patients recovered and no longer showed signs of the pathogen.

    Summary Acute thrombosis of cerebral veins and sinuses (ATCVS) is a multifactorial disease with grave consequences. Because of its rare occurrence there are no proven treatment guidelines. Sixteen patients with ATCVS were treated. The final diagnosis was confirmed by digital subtraction angiography. Sinus catheterization was performed via transfemoral venous access. Treatment included mechanical manipulation of thrombi and thrombolytic therapy. A regression of clinical symptoms with a concomitant decrease of intracranial hypertension was achieved in all patients. Long-term results were studied in eight patients: none presented clinical signs of intracranial hypertension. Endovascular transvenous recanalization is an effective treatment for acute thrombosis of cerebral veins and sinuses. Along with the local thrombolysis, significant potential in the treatment of this complex pathology lies in the transvenous endovascular techniques of mechanical thrombus extraction, especially in patients with intracranial hemorrhage for whom the use of thrombolytic agents is restricted.

    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 purpose of the present work is a clinical study of photodynamic therapy of maxillary sinusitis. 0.1%-Methylene Blue aqueous solution in combination with He-Ne laser irradiation (632.8 nm) have been used for treatment of maxillary sinus mucous of patients with acute and chronic maxillary sinusitis. The differences between the results of the treatment with dye and light versus treatment with a drug for every group of patients were statistically analyzed by Student’s t test. The efficacy of the photodynamic therapy was estimated with the use of the following criteria: the state of respiration, olfaction, duration of purulent discharge, reconstruction of transport function of ciliary epithelium, etc. The obtained results have shown that the photodynamic therapy is effective in comparison with conservative methods of treatment of the disease.

    The silent sinus syndrome (SSS) is a rare clinical entity characterized by painless spontaneous enophthalmos, hypoglobus, and facial deformities secondary to chronic maxillary sinus atelectasis. The aim of this study was to present an SSS diagnostic feature and evaluate the relationship between nasal septum deviation and maxillary sinus volume. A retrospective chart review of the clinical characteristics of 20 patients diagnosed with SSS between January 2013 and July 2014 were analyzed by the Department of Otorhinolaryngology of University Hospital Complex of Santiago de Compostela. 14 patients were females and six males. The mean age was 43 years (range 28-67 years). The right maxillary sinus was involved in 12 patients and the left maxillary sinus in eight patients. There was no statistical difference between gender and the presence of SSS. Maxillary sinus sizes were significantly smaller on the same side as the deviation (p < 0.01). 14 patients were treated with functional endoscopic sinus surgery (FESS) with maxillary antrostomy. We concluded that patients with SSS usually present with facial asymmetry, and the best approach to document and show all facial asymmetries for these patients are the frontal and craneo-caudal photographs. The present study demonstrates that, in adult patients, SSS generally presents a septal deviation to the affected maxillary sinus. We recommend performing a paranasal sinus CT scan when the patient has a deviated nasal septum, retraction of the malar eminence (evidenced from the viewpoint cranio-caudal facial) and hypoglobus. FESS performing postero-anterior uncinectomy and enlargement of the maxillary ostium is recommended to restore sinus pressure and prevent progression of the enophthalmos, hypoglobus and facial deformities.

    The silent sinus syndrome (SSS) is a rare clinical entity characterized by painless spontaneous enophthalmos, hypoglobus, and facial deformities secondary to chronic maxillary sinus atelectasis. The aim of this study was to present an SSS diagnostic feature and evaluate the relationship between nasal septum deviation and maxillary sinus volume. A retrospective chart review of the clinical characteristics of 20 patients diagnosed with SSS between January 2013 and July 2014 were analyzed by the Department of Otorhinolaryngology of University Hospital Complex of Santiago de Compostela. 14 patients were females and six males. The mean age was 43 years (range 28-67 years). The right maxillary sinus was involved in 12 patients and the left maxillary sinus in eight patients. There was no statistical difference between gender and the presence of SSS. Maxillary sinus sizes were significantly smaller on the same side as the deviation (p < 0.01). 14 patients were treated with functional endoscopic sinus surgery (FESS) with maxillary antrostomy.

    A three-year-old girl with multiple heart malformations admitted to the pediatric cardiology unit because of excessive sweating and fatigue. Abnormal color Doppler flow was detected into the right atrium from the dilated coronary sinus on the echocardiographic examination, and ruptured sinus Valsalva aneurysm (SVA) was diagnosed. Although in most such cases, an antegrade transcatheter approach has been used, a retrograde approach can be used as a cost-effective treatment modality in those cases with selective high-risk surgery. In this report, we present a patient with ruptured SVA, which was closed via Amplatzer vascular plug-4 by retrograde approach. PMID:24769826

    Paget's disease of the bone is a disorder characterized by abnormal breakdown and formation of bone tissue. The cause is believed to be either viral or genetic in origin. Most of the time, patients are asymptomatic. Diagnosis is supported by findings from multiple modalities including serum markers, imaging, bone scans, and histology. We present a rare case of Paget's disease of the bone involving the frontal sinus. We review the relevant clinical, diagnostic, and histological findings. We also suggest indications for the management of monostotic Paget's disease of the frontal sinus. PMID:24383031

His pupils were spared, his eye movements were not restricted and he was not proptosed. A prompt CT orbits and head scan revealed a large left frontal sinus mucocoele that had eroded into the left orbit. The patient had successful endoscopic sinus surgery under the ear, nose and throat team and 1 month later was seen in ophthalmology clinic. His ptosis and discomfort had fully resolved and he had no neurological sequelae from the surgery.

    Acute ethmoiditis is a rare infection of ethmoidal cells. The pathognomonic sign is an edema of the internal corner of the eye. Imaging may be necessary to verify the absence of orbital or endocranial complications. Thrombophlebitis of the cavernous sinus is a serious complication of this infectious process. We report the case of an 11-year-old boy who presented with ethmoiditis complicated with thrombophlebitis of the cavernous sinus, with right hemiplegia and left Bell palsy sequelae. Early diagnosis of this disorder and urgent therapy are essential. Treatment is based on the antibiotic therapy. PMID:24290188

    Introduction: We report on a case of isolated metastatic breast cancer to the medial rectus muscle. This entity is exceedingly rare. Case: A 44-year-old female with a history of breast cancer presented with unilateral maxillary symptoms and was treated for sinusitis. Over time, she developed ocular pain, diplopia, blurred vision and eventually complete adduction deficit. Results: T1-weighted magnetic resonance imaging revealed a medial rectus lesion. Biopsy via transnasal transorbital endoscopic approach revealed metastatic mammary carcinoma. Discussion: Metastatic disease to the orbit should be considered in the differential diagnosis of refractory maxillary sinus pain in patients with a known underlying malignancy. PMID:27103558

    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

    Malignancies of the nose, sinus, and skull base are rare. The most common histologies are squamous cell carcinoma and adenocarcinoma. The most common primary sites are the nasal cavity and maxillary sinus. Management of these tumors is technically challenging because they often present in advanced stages with extensive disease invading important structures such as the orbit and the skull base. In the last few decades advances in surgical resection techniques, as well as improved strategies to deliver adjuvant radiation, have substantially improved the outcomes in patients with malignancies of the sinonasal tract and skull base.

    The clinical results of photodynamic therapy of maxillary sinusitis have been presented. 0.1%-Methylene Blue aqueous solution in combination with He-Ne laser irradiation (632.8 nm) has been used for treatment of patients with acute and chronic maxillary sinusitis. Efficacy of the photodynamic therapy was estimated with the use of the following criteria: the state of respiration, olfaction, duration of purulent discharge, reconstruction of transport function of ciliary epithelium, etc. The obtained results have shown that the photodynamic therapy is effective in comparison with conservative methods of treatment of the diseases.

    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. PMID:26851444

    Background: Ectopic eruption of a tooth or osteoma rarely occurs within the maxillary sinus. Coexistence of these two rare entities in the maxillary sinus has never been reported in the English literature. Case Report: Herein, we present a 21 year-old male patient with osteoma and ectopic tooth in the left maxillary sinus treated with the removal of the ectopic tooth by endoscopic sinus surgery and excision of the osteoma by the Caldwell-Luc procedure. Conclusion: Unique coexistence of two different entities in the maxillary sinus is most likely due to pediatric facial trauma. Pediatric patients with maxillofacial trauma should be carefully watched for dental injury both clinically and radiologically. PMID:27606148

    Although hormonal influences, inflammation, trauma, sinus thrombosis, venous hypertension, and congenital origin have been proposed as sources of dural arteriovenous fistulas (DAVFs) in cavernous and sigmoid sinuses, the etiology of these lesions remains controversial. We present a case with a cavernous sinus DAVF developed from viral meningitis which has not been previously described. A 24-year-old male was admitted to our institute because of periorbital pain, decreased vision, pulsatile tinnitus, chemosis, and exophthalmos on the right side after he had suffered viral meningitis four months before. Cerebral angiography demonstrated a cavernous sinus DAVF, which was successfully obliterated with several platinum coils using a transvenous approach. The viral meningitis most likely caused the inflammation, that may be responsible for the occurrence of the cavernous sinus DAVF. Prompt treatment for inflammation may help to prevent the development of DAVFs.

    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).

    Sinus osteoma is a common nasal and sinus disease, while the clinical cases of osteoma with a diameter greater than 30 millimeter are rarely seen. This paper reports a case of a 39-years-old male patient discovered with one-year long swelling pain in the right eye. The patients' right eye was mildly prominent and he suffered from hypopsia and diplopia. After CT scanned, he have ethmoid osteoma been discovered, besides, the right media rectus compression and orbital apex compression and consequent pathologically were diagnosed. The solid tumor ranged widely from the anterior skull base to the superior and interior orbital walls,and thus deprived the patient's complete surgical resection. As an attempt to prevent complications, most parts of the tumors were sur gically removed.

    The nose and sinuses are constantly exposed to the huge quantities of gases needed to maintain life. Not only is the human nose well-equipped to warm and humidify this inhaled air, but it is also uniquely able to clean much of it. Any material other than physiologic amounts of oxygen, nitrogen, carbon dioxide, and water that accompanies the airstream can be considered a pollutant, and this pollutant could potentially injure the individual. The following discussion will review the defense mechanisms that allow the nose and sinuses to protect the lower airways. The effects of pollutants on the respiratory mucosa will then be described, including some recent trends in those effects. These trends include specific population consequences of indoor and outdoor air pollution, and changes in risk for individuals in several occupations. Throughout these discussions, specific areas that would benefit from further research will be mentioned.68 references.

    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.

    Intracranial complications of sinusitis are rare but life threatening. We present a case of a 17-year-old woman with sinusitis who deteriorated over the course of 12 days from subdural empyema and global purulent cerebral venous sinus thrombosis. The patient was managed with surgery and mechanical thrombectomy utilizing a novel 'stent anchor with mobile aspiration technique', in which a Trevo stent retriever (Stryker) was anchored in the superior sagittal sinus (SSS) while a 5 MAX ACE reperfusion catheter (Penumbra) was passed back and forth from the SSS to the sigmoid sinus with resultant dramatic improvement in venous outflow. The patient was extubated on postoperative day 3 and was discharged with minimal lower extremity weakness on postoperative day 11. This is the first report using the Trevo stent retriever for sinus thrombosis. It is important to keep these rare complications in mind when evaluating patients with oral and facial infections.

    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.

    Although sinus node dysfunction (SND) and atrial arrhythmias frequently coexist and interact, the putative mechanism linking the 2 remain unclear. Although SND is accompanied by atrial myocardial structural changes in the right atrium, atrial fibrillation (AF) is a disease of variable interactions between left atrial triggers and substrate most commonly of left atrial origin. Significant advances have been made in our understanding of the genetic and pathophysiologic mechanism underlying the development and progression of SND and AF. Although some patients manifest SND as a result of electric remodeling induced by periods of AF, others develop progressive atrial structural remodeling that gives rise to both conditions together. The treatment strategy will thus vary according to the predominant disease phenotype. Although catheter ablation will benefit patients with predominantly AF and secondary SND, cardiac pacing may be the mainstay of therapy for patients with predominant fibrotic atrial cardiomyopathy. This contemporary review summarizes current knowledge on sinus node pathophysiology with the broader goal of yielding insights into the complex relationship between sinus node disease and atrial arrhythmias.

    Background and aims To asses, by using the Cone Beam CT (CBCT) reformatted images, the presence of anatomical variants of the sinonasal cavities and to determine the correlation of these variations with the onset of maxillary sinus inflammations. Method The study is a retrospective one and consists of the investigation of 130 patients with CBCT imaging, patients that were referred to the Maxillo-Facial Clinic, Radiology Department of the Iuliu Hatieganu University of Medicine and Pharmacy in Cluj-Napoca, for clinical symptoms of sinusitis within a period of 24 months. The images were analyzed for the presence of different anatomical variations and sinus inflammation. The CBCT images were obtained using a NewTom 3G scanner and the data acquired were statistically analyzed using Chi-square test, Odds ratio data and confidence intervals, with a determined p<0.05 considered to be statistically significant. Results The anatomical variants were detected both in the inflammation and control group. From the spectrum of variations concha bullosa, deviation of uncinate process and asymmetrical ethmoid roof presented significant association with sinusitis. The deviated position of the uncinate process appeared in more than 50% of patients in the positive group [OR=2.55] compared with a third of the control group. Concha bullosa was observed in 31% cases, 23% in the control group and 34% in the positive group [OR=1.73]. Haller cells showed a small difference between groups [OR=1.14] whereas the ethmoid roof asymmetry was evidently more prevalent in the inflammation group. Conclusion The anatomical variants of the paranasal sinuses are not incidental, being found in a large number of patients and may be a predisposing factor in the onset and recurrence of sinuses inflammation. The CBCT technique, due to the finest multiplanar reconstruction, permits a very good pre-therapeutic assessment of these predisposing conditions. PMID:27547064

    Cavernous sinus thrombosis is a rare presentation. Early diagnosis and aggressive treatment are required to prevent morbidity and mortality. Nasal infections can give rise to serious intracranial complications. Presented here is a case series of cavernous sinus thrombosis of nasal septic origin. The purpose of this article is to report our experience in pediatric patients with this illness to ascertain a clinical course and outcomes for further clinical application. Eight (08) cases of nasalseptic origin of cavernous sinus thrombosis ata tertiary care teaching hospital in the north India region of India were included in the study. Cases presented with various symptoms like headache, proptosis, ophthalmoplegia and fever. The patients were investigated by doing High Resolution Computed Tomography of nose & PNS and brain with intravenous contrast. The cases were treated with intravenous broad spectrum antibiotics. Eight patients less than 16 years of age (mean age of 11.2 years)diagnosed with cavernous sinus thrombophlebitis due to nasal septic focus over the period of 05 years were reviewed retrospectively. The predisposing infections and causative microorganisms were similar to previous reports in children. A conservative management strategy with antibiotics gave a good prognosis in these cases. There were no deaths. Early recognition of this condition, the appropriate selection of empirical antibiotic therapy, and the awareness of associated complication were the key factors leading to excellent outcome.

    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

    Non-traumatic nasal septal abscess is rare, commonly seen in patients with poor immunity, and presents as isolated nasal septal abscess. Further, nasal septal abscess complicated with acute sinusitis is rather rare. Very little literature has been generated for non-traumatic nasal septal abscess complicated with acute sinusitis in healthy patients. Prompt diagnosis and adequate treatment will help to prevent the complications associated with nasal septal abscess such as saddle nose and intracranial involvement. Herein, to our knowledge, we present the first case involving an otherwise healthy little girl with nasal septal abscess complicated with acute sinusitis and facial cellulitis.

  3. Concha bullosa mucocele with orbital invasion and secondary frontal sinusitis: a case report

    PubMed Central

    2013-01-01

    Background Although concha bullosa (CB) is the most common variants of the middle turbinate, mucocele of CB is uncommon. Furthermore, CB mucocele with orbital invasion and secondary frontal sinusitis has not been reported previously. Case presentation A 42-year-old Korean male presented with gradually progressive proptosis of right eye and right-sided frontal headache. He had previously undergone endoscopic sinus surgery (ESS) 15 and 9 years ago. The endoscopic examination showed an expansive, large middle turbinate with normal mucosa filled the majority of right nasal cavity and displaced the septum to the left. A computed tomography and magnetic resonance imaging showed a well demarcated cystic huge mass at right nasal cavity extending to ethmoid sinus and orbit. The mass caused a bony defect on the lamina papyracea and displaced medial rectus muscle and orbit laterally. Moreover, the right frontal and ethmoid sinus was totally opacified. This article reports orbital invasion and frontal sinusitis complicating a CB mucocele, which was successfully treated by endoscopic resection of the lateral wall of CB and frontal sinusotomy. Conclusions This case illustrates that CB mucocele could develop to such a massive extent that it leads to orbital complication and secondary frontal sinusitis. Therefore, we consider this entity in the differential diagnosis of orbital complications and secondary sinusitis caused by intranasal mass. PMID:24299615

    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.

    We present a case of a 45-year-old man with an incidental and longstanding diagnosis of extensive mediastinal and cardiac lipomatosis. Along the years, he had experienced various arrhythmias, mainly bradyarrhythmias, mostly asymptomatic. Recently after documenting a sinus pause of 6 seconds and runs of nonsustained ventricular tachycardias, he underwent an implantation of a cardioverter-defibrillator. There are many reports of cardiac lipomatosis in the literature, including reports of related ventricular arrhythmias, some of which are fatal. (PACE 2010; 513-515).

    A 58-year-old woman with acromegaly developed massive epistaxis 7 days following trans-sphenoidal resection of a growth hormone-secreting pituitary adenoma. At autopsy, it was determined that the source of the hemorrhage was a rupture of the intracavernous segment of the internal carotid artery secondary to a bacterial arteritis. We describe the gross dissection and histologic examination undertaken in this unusual case, discuss the possible etiology of the infection and review the potential complications of this surgical approach with a view to improving forensic examination of these patients.

    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.

To the best of our knowledge, <5 cases have been reported in the last 20 years in the English literature, so far, only one of which has been infantile type in a 15 months old girl. In this case report, we will explain our experience with a rare case of infantile fibrosarcoma originating from ethmoid sinus in a 5-year-old boy who presented with dyspnea and epistaxis. After biopsy, it was diagnosed as fibrosarcoma of sinus origin. PMID:26604519

    We present a typical case of acute suppurative thyroiditis (AST), associated with a piriform sinus fistula. We illustrate the case with an ultrasound picture of a hypoechogenic perithyroid mass and a CT scan using intravenous iodine contrast showing a perithyroid hypodense mass with peripheral enhancement, the mass also having intrathyroid involvement. When clinical and radiological findings suggest the presence of AST, it is necessary to rule out the presence of a piriform sinus fistula by means of a radiological study with barium contrast. Piriform sinus fistula is a rare abnormality derived from the branchial arch which is directly related to recurrent episodes of AST; surgical excision is hence, necessary to avoid such episodes.

    A case of balloon frontal sinuplasty in a 12-year old male with intracranial abscess from acute sinusitis is presented. The patient experienced photophobia, fever, headache, nausea and vomiting. Frontal sinusitis with intracranial abscess was diagnosed on imaging. The patient was taken to the operating room for drainage with left frontal balloon sinuplasty. The patient showed immediate clinical improvement, did not suffer from any complications of surgery and was further managed with long term intravenous antibiotics. We believe that balloon frontal sinuplasty is potentially safe and effective in the treatment of complicated acute frontal sinus obstruction in children.

    Intraoperative bleeding during endoscopic sinus surgery poses an additional dimension to an already technically challenging surgical approach because of the narrow sinonasal surgical field, single working hand, and the use of endoscopic instruments. Poor visualization is one of the most important factors that increase the risk of intraoperative complications such as inadvertent injury to major vessels and nerves, and incomplete surgery. This article provide a logical approach to improving the surgical field, minimizing risk of inadvertent vascular injury, and managing intraoperative bleeding. PMID:27267017

    Recently, solitary fibrous tumors (SFTs) have been reported in the head and neck area, such as the nasal cavity, thyroid, salivary gland, etc. We present a rare case of SFT which arose from the sphenoethmoidal recess of the nasal cavity, penetrating into the sphenoid sinus, and which showed different intensities on magnetic resonance imaging (MRI) according to the occupied locations. T2 weighted magnetic resonance (MR) images showed low intensity in the nasal cavity, and iso-intensity in the sphenoid sinus. Enhancement with gadolinium contrast on T1-weighted images was more remarkable in the sphenoid sinus than in the nasal cavity. While the tumor in the nasal cavity showed abundant collagen and high cellularity in microscopic examination, numerous small vessels and dilated vascular spaces were remarkable in the tumor of the sphenoid sinus. MRI findings corresponded to pathological findings. We review SFTs in the head and neck area in the English literature.

    After a review of the anatomy of the cavernous sinuses (CS), this work presents the clinical picture and imaging protocol of lesions which occur in this area. It outlines extension and imaging features of these lesions. It emphasises MRI appearance, such as T1, T2 and diffusion signal, type of contrast medium uptake. A complementary CT scan is performed if an associated abnormality of the base of the skull is suspected on MRI (lysis, condensation). This paper proposes a straightforward classification system depending on imaging and sets out the principal symptoms of the main aetiologies of CS lesions which are represented by various diseases such as tumours, inflammations, vascular abnormalities. Complementary to imaging, their diagnosis is based on clinical data i.e. known cancer, signs suggesting inflammation. Its rich iconography allows this article to be used as a reference in current clinical practice. PMID:24099909

    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. PMID:27352844

    The authors report a boy aged 9 years in whom a giant meningioma of the small wing of the sphenoidal bone was removed surgically. Attention is called to the rarity of these tumours in the first decade of life. Developmental retardation, speech beginning at the age of 4 years, large head and epileptic seizures developing at the age of 7 years without signs of intracranial hypertension suggested the possibility of organic brain disease and development of massive hemiparesis, speech disturbances and choked disc in the last period of the disease were the cause of referral of the child to a neurosurgical unit. Plain skull films and angiography demonstrated changes typical of raised intracranial pressure and presence of an expanding lesion in the left cerebral hemisphere. Meningioma was found on operation hidden within the left frontal and temporal lobes but connected by means of a narrow band to the dura of the small wing of the sphenoidal bone. A good result was obtained. Follow-up examination after 2 years demonstrated slight neurological abnormalities and a very good general state of the child. PMID:1186962

    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

    ABSTRACT The present case report is of trauma episode of the lower anterior teeth, causing pulpal necrosis with periradicular periodontitis, resulting in the occurrence of cutaneous sinus tracts (fistula). Previous misdiagnosis and inappropriate medical treatment were ineffective. Only when properly referred to dentists, the differential diagnosis was made. The guideline to diagnose cutaneous sinus tracts (fistula) is based mainly on accurate pulp sensitivity tests of the involved traumatized teeth. Intraoral and dental examinations are critical in making the diagnosis. The case presented here shows that cutaneous odontogenic sinus tracts associated in traumatized teeth, even in absence of caries or tooth fracture. How to cite this article: Mishra R, Khan TS.

    Tolosa-Hunt syndrome, an idiopathic granulomatous inflammation of the cavernous sinus, is primarily a diagnosis of exclusion. The majority of patients present with unilateral orbital pain and features suggestive of paralysis of one or more of the cranial nerves passing through the cavernous sinus and/or superior orbital fissure. MRI of the head may show unilateral enhancement of the cavernous sinus and orbital apex. Treatment is with high-dose intravenous steroids followed by tapering oral steroids. Rapid amelioration of pain within 24-48 h supports this rare diagnosis. Resolution of neuropathies may take longer. We describe a case of a young man who presented with left periorbital pain, complete ophthalmoplaegia and ptosis of the left eye. MRI showed enhancement of the left cavernous sinus and orbital apex. High dose steroids led to complete resolution of pain, while ptosis and ophthalmoplaegia improved gradually. PMID:26294359

    Objective: A description is made of transcrestal sinus lift using the sinus balloon technique, evaluating the bone height achieved and implant success one year after prosthetic loading. Material and method: Between January and July 2007, transcrestal sinus lift using the sinus balloon technique for dental implant placement was carried out in 6 patients. A panoramic X-ray study and maxillary computed tomography scan were carried out before the operation, in order to discard possible sinus pathology. During the intervention, the integrity of the sinus membrane was evaluated using a Medi Pack Pal endoscope (Farol Store and Co., Tuttlingen, Germany), and the intraoperative complications were analyzed. The dental implants were placed in the same surgical step in the presence of 3 mm or more of residual bone. Following the operation, panoramic X-rays were used to assess the bone height gained. One year after prosthetic loading, the implant success rate was determined based on the criteria of Buser. Results: One patient was excluded due to Schneider’s membrane perforation as confirmed by endoscopy. Trans-crestal sinus lift was carried out in 5 males with a mean age of 41.6 years (range 27-51), without antecedents of sinus disease. There were no intraoperative complications. In four patients the implants were placed simultaneous to sinus lift, while in another case implant placement was postponed due to insufficient remaining bone height. The mean gain in height after the operation was 8.7 mm. One year after prosthetic loading, the implant success rate was 100%. Conclusions: Transcrestal sinus lift using the sinus balloon technique is a minimally invasive procedure. In 5 patients the bone height gained proved sufficient to allow implant placement even in the presence of 3 mm of residual bone. Key words: Sinus lift, balloon, sinus complications. PMID:22157670

    Congenital sinus of Valsalva aneurysms are extremely rare in Spain. The lesion consists of a defect that allows the aortic media to separate from the annulus fibrosus of the aortic valve, causing it to dilate with arterial pressure. The natural course of the aneurysm involves the risk of complication due to bacterial endocarditis, with conduction blocks or myocardial ischemia. Rupture of the aneurysm, usually into a right chamber, causes a left-right shunt that leads to heart failure and death if untreated. We present the case of a previously asymptomatic 60-year-old woman who presented with a clinical picture that led to a diagnosis of hyperthyroidism, and in whom there occurred a coincident rupture of a congenital sinus of Valsalva aneurysm. We describe the anesthetic procedure and emphasize the importance of intraoperative echocardiography throughout the resection of the aneurysm.

    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.

    Pilonidal sinus disease (PSD) most commonly presents in young men when hair follicles enter through damaged epithelium and cause an inflammatory reaction. This results in the formation of fistular tracts. We reviewed studies based on a shared cohort of patients who presented at German military hospitals with PSD. The effect of the morphology of the sinus, perioperative protocol, and aftercare of the surgical treatment on the recurrence of PSD were evaluated. The drainage of acute abscesses before surgery, the application of methylene blue during surgery and open wound treatment were generally found to reduce the recurrence rate. A positive family history, postoperative epilation and primary suture as the healing method were found to elevate the recurrence rate. Long-term follow up of over 15 years was found to be a vital component of patient care as only 60% of the overall recurrences recorded had taken place by year 5 postoperatively.

    Antral mucoceles are a separate entity that must be distinguished from the common, dome-shaped lesions of the floor of the sinus that are also often, although inaccurately, referred to as mucoceles. The latter lesions are known by a variety of names, including pseudocysts, and are innocuous. True antral mucoceles are potentially destructive lesions that are often secondary to trauma, especially the Caldwell-Luc procedure. This article describes in some detail the clinical, radiologic, and histopathologic features of true antral mucoceles. One type of antral mucocele, commonly seen in Japan, is referred to as a postoperative maxillary cyst and is identical to the surgical ciliated cyst of the maxilla originally reported by Gregory and Shafer.

    The sinus gland of Cardisoma carnifex was examined by light and transmission electron microscopy. This neurohemal organ is composed primarily of enlarged, branching axon terminals with numerous finger-like projections, which act as storage and release sites for neurohormones that are assumed to be contained in membrane-bound, electron-dense neurosecretory granules. Also present in the sinus gland are glial cells with cytoplasmic processes which form elaborate wrappings around neurosecretory terminals, and an acellular fibrillar lining of the branching blood sinus. Six types of neurosecretory terminals are identified on the basis of granule size, granule density, and density of the axoplasmic matrix. Images supporting the abutting the blood sinus lining are found. Large multilamellate bodies appear in terminals depleted of neurosecretory granules and may be involved in the recycling of granule membrane.

    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.

    The opening of the frontal sinus is a common occurrence in surgical practice. It may involve many surgical disciplines. The complications that may derive from incorrect treatment of an opened frontal sinus are potentially fatal. Unfortunately, the treatment of patients with injured frontal sinus is not uniform and standardized. Here, we describe our technique of treatment. We propose our treatment modality on the basis of our personal experience, which has been excellent in the past 20 years, that is from the time of the technique's introduction and routine application.

    Cementoblastoma is a rare neoplasm, representing <1% of all odontogenic tumors. It usually occurs in the posterior mandible and is associated with roots of a mandibular first molar or second premolar. This paper presents a rare case of cementoblastoma in the maxillary posterior region involving the maxillary sinus, in a young female patient. The clinical, radiological, and histopathological features of the lesion are discussed along with a review of previously reported cases in the literature. PMID:26389052

    2012-09-01

    Osteomas of the cranial sinuses are rare, benign bony tumors that can be complicated by the formation of an intracranial pneumatocele. If not treated promptly, a pneumatocele can lead to abscess formation, meningitis, or ventriculitis. In the present case, an intracerebral pneumatocele was formed when an 18 cm(3) osteoma breached the posterior wall of the frontal sinus creating a one-way valve through which air could enter the intracranial cavity. The patient presented after forceful sneezing with nonspecific symptoms of headache, nausea, and vomiting. CT demonstrated a frontal collection of loculated air with mass effect within the left cerebral hemisphere. A partly mineralized mass occupied the left superior nasal ethmoid sinus and left frontal sinus. Of interest pathologically in this case, the tumor had a substantial osteoblastoma-like component. Surgical repair involved frontal craniotomy to remove the osteoma and debride frontal sinus mucosa, plugging the frontal nasal ducts and sinus with fat and bone wax, and dural restoration using an underwater closed drainage system to vent intracranial air and stabilize the patient.

    Six patients were treated for gradual onset of enophthalmos, a deep superior sulcus and globe ptosis. There was no history of orbital trauma or sinusitis. CT scan showed an opacified shrunken maxillary sinus with dehiscence and depression of the orbital floor and downward displacement of the orbital contents. Pathological review of the surgical specimens showed a respiratory mucosal lining with thick mucoid secretions, new bone formation, but no purulence. The etiology is thought to be maxillary sinus mucocele. Surgical treatment with an otolaryngologist consisted of a Caldwell-Luc procedure to evacuate the maxillary sinus with nasal antrostomy and an orbital floor exploration with insertion of a methylmethacrylate implant molded at the time of surgery to reform the orbital floor and reposition the globe. Follow-up of 2 1/2-4 years shows excellent functional and cosmetic results.

    We report a 57-year-old man with intraparenchymal pneumocephalus caused by ethmoid sinus osteoma. He had a history of severe allergic rhinitis, which caused him to frequently blow his nose, and he was referred to our hospital with headache and mild left hemiparesis. CT scans revealed a large volume of intraparenchymal air entrapped in the right frontal lobe related to an osteoma in the ethmoid sinus. The osteoma eroded the upper wall of the sinus and extended into the anterior cranial fossa. At operation, we observed that the osteoma had protruded intracranially through the skull base, disrupted the dura and extended into the frontal lobe. To our knowledge, this is the first report of a patient with intraparenchymal pneumocephalus caused by an ethmoid sinus osteoma.

    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.

    Methamphetamines are the second most commonly used illicit drug worldwide and cost the United States health-care system ∼$23.4 billion annually. Use of this drug affects multiple organ systems and causes a variety of clinical manifestations. Although there are commonly known sequelae of methamphetamine abuse such as "meth mouth," there is limited evidence regarding maxillary sinus manifestations. The following cases highlight the initial evaluation and management of two methamphetamine abusers with loculated purulent collections within the maxillary sinus as a result of methamphetamine abuse. Our aim was to delineate the otolaryngologic symptoms associated with the patients' methamphetamine abuse. Computed tomography and magnetic resonance imaging studies revealed loculated purulent collections within the maxillary sinus of probable odontogenic origin in both patients. Methamphetamine abuse leading to rampant caries and poor oral hygiene may predispose individuals for craniofacial infections and fluid collections. These cases illustrate the development of maxillary sinusitis and maxilla mucoceles that have been associated with methamphetamine use.

    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.

    Comprehension of the complex anatomic variants comprising the frontal sinus outflow tract is essential for successful surgical intervention. Deviation from sound technique increases the potential for a variety of deleterious sequelae, including recurrent disease as well as catastrophic intracranial and orbital injury. Furthermore, incomplete removal of elements occluding the frontal recess can result in severe stenosis that can increase the difficulty of further interventions. This review covers anatomic considerations that should be kept in mind when performing frontal sinus surgery. PMID:27329978

    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.

    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.

    In order to evaluate the relative role of the automatic nervus system and of the intrinsic electrophysiologic properties on the sinus node function, we measured the corrected sinus node recovery time before and after autonomic nervous system blockade in 24 patients. Fourteen had a sick sinus syndrome, five had a carotid sinus syncope, two had syncope of unknown origin associated with bradycardia. Beta blockade was obtained by infusing metoprolol intravenously at a dosage of 0.2 mg/kg; complete automatic blockade was achieved by further i.v. administration of atropine at a dosage of 0.04 mg/kg. After beta blockade, the corrected sinus node recovery time increased in patients with sick sinus syndrome and intrinsic slow heart rate, whereas it decreased in patients with carotid sinus syncope or with syncope and bradycardia. In patients with sick sinus syndrome and normal intrinsic heart rate the response was variable. A positive direct correlation was found between the changes of the corrected sinus node recovery time induced by beta blockade and those induced by autonomic blockade; that is, both either prolonged or shortened the corrected sinus node recovery time. The changes of the corrected sinus node recovery time after beta blockade alone were inversely correlated with the intrinsic heart rate. We conclude that patients with intrinsic depression of the sinus node have an increased sympathetic tone.

    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.

    Otolaryngologists are called upon to evaluate and treat sinonasal masses discovered incidentally on imaging studies. Although common conditions such as sinonasal polyps and mucus retention cysts predominate, it is prudent practice to formulate a differential diagnosis to identify unusual conditions. We present a case of a maxillary sinus mass in a 78-year-old man that was discovered incidentally on brain imaging and subsequently identified on biopsy as an angiomyolipoma (AML). AMLs are benign hamartomatous tumors that rarely occur in extrarenal locations. Only a few cases have been reported in the nasal cavity. We believe our case represents the first reported instance of AML arising within a maxillary sinus. Identification of intratumoral fat within the mass on imaging studies may suggest the diagnosis of AML preoperatively. Close interdisciplinary collaboration among the otorhinolaryngology, radiology, and pathology services is beneficial for patient management. We report this case to raise awareness that AML can arise in this previously unreported location. Moreover, we wish to emphasize that AML should be considered in the differential diagnosis when imaging studies demonstrate a well-defined, heterogeneous, fat-containing solitary mass in the nasal cavity or maxillary sinus.

    Myoepithelial carcinoma is characterized by nearly exclusive myoepithelial differentiation and evidence of malignancy. It may arise de novo or in preexisting benign tumors including pleomorphic adenoma and benign myoepithelioma. A 39-year-old lady presented with painless progressive swelling on the right cheek and right side of palate. On surgery, there was a mass in right maxillary sinus which was surgically excised and diagnosed on histopathology as pleomorphic adenoma. Subsequently, there were two recurrences. The first recurrence was in the right maxilla after 2 years that was removed surgically and diagnosed as pleomorphic adenoma. One year later, she came with rapidly progressive swelling in bilateral cheeks and face. Intraoperatively, there was a large tumor in both maxillary sinuses with extensive local infiltration. Histologically, it was diagnosed as myoepithelial carcinoma. Carcinoma ex pleomorphic adenoma is usually a high grade malignancy. It occurs most commonly in parotid gland followed by submandibular glands, minor salivary glands and occasionally in sublingual gland. To the best of our knowledge, this is the first case of myoepithelial carcinoma arising in a recurrent pleomorphic adenoma in the maxillary sinus.

    We hypothesized that normal sinus rhythm-sinus bradycardia is common in young children following extracardiac Fontan. After excluding patients with sinus pauses, junctional rhythm, tachy-brady syndrome, frequent ectopics, or ectopic atrial rhythm, we found an ambulatory 24-h Holter monitor average heart rate of 78 ± 12 beats per minute (bpm) in 33 post-extracardiac Fontan children with a median age of 6 years (5-10). A 24-h average heart rate of 78 ± 12 bpm is statistically significantly lower than a 24-h average heart rate value of 90 ± 10 bpm derived from a similarly aged control population (p < 0.01). We conclude that after excluding those with significant arrhythmias, normal sinus rhythm-sinus bradycardia is common in children post-extracardiac Fontan.

    In the present study, the effects of endoscopic sphenoidotomy surgery on the flow patterns and deposition of micro-particles in the human nasal airway and sphenoid sinus were investigated. A realistic model of a human nasal passage including nasal cavity and paranasal sinuses was constructed using a series of CT scan images of a healthy subject. Then, a virtual sphenoidotomy by endoscopic sinus surgery was performed in the left nasal passage and sphenoid sinus. Transient airflow patterns pre- and post-surgery during a full breathing cycle (inhalation and exhalation) were simulated numerically under cyclic flow condition. The Lagrangian approach was used for evaluating the transport and deposition of inhaled micro-particles. An unsteady particle tracking was performed for the inhalation phase of the breathing cycle for the case that particles were continuously entering into the nasal airway. The total deposition pattern and sphenoid deposition fraction of micro-particles were evaluated and compared for pre- and post-surgery cases. The presented results show that sphenoidotomy increased the airflow into the sphenoid sinus, which led to increased deposition of micro-particles in this region. Particles up to 25 μm were able to penetrate into the sphenoid in the post-operation case, and the highest deposition in the sphenoid for the resting breathing rate occurred for 10 μm particles at about 1.5%.

    The [symbol: see text] sinus-catheter was used to treat purulent sinusitis with septal perforation or defective septum of the sinuses. The procedure described implies simultaneous introduction of two sinus-catheters the functioning channels of which unite into one output by means of T-joint. The method has been successfully tried in the treatment of exudative and aggravated chronic purulent hemisinusitis (6 cases). The authors hold that communication between nasal sinuses is not a contraindication for sinus-catheter application. This fact widely extends potentialities of its use.

    We report two young patients with symptomatic sick sinus syndrome admitted for permanent pacemaker implantation (PPI). On evaluation with echocardiography, one of them was found to have persistent left superior vena cava and venography showed absent right superior vena cava also. He underwent PPI with leads inserted via left superior vena cava, coronary sinus, right atrium and right ventricle. The other patient was incidentally found to have interrupted inferior vena cava with azygos continuation while being planned for temporary pacemaker implantation. She underwent successful PPI. We would like to stress the importance of having a high suspicion for these systemic venous anomalies in patients presenting with sick sinus syndrome especially at young age. If we could diagnose preoperatively, we can avoid on table surprises. PMID:27326354

    Background The aim of this study was to simulate implant placement in the maxillary sinus septum, as a potential alternative site to avoid sinus grafting. Material/Methods One hundred partially or completely edentulous patients, with their maxillary sinus septum present in the edentulous region, were selected from the database of the Department of Maxillofacial Surgery, Cliniques Universitaires Saint Luc, Bruxelles, Belgium. Three-dimensional (3D) reconstructions were created using 3D planning software. 3D reconstructions were performed for each maxillary sinus. Using the software implant library, the implants that presented the best fit with the maxillary sinus septum and that followed the established inclusion criteria were selected. Results All of the implants were inserted in premolar and molar regions. Most implants were inserted in the position of the second molar (21 of 55) or in the position of the first molar (17 of 55). In all sites the most frequently used implant was 4 mm in diameter and 7 mm in height. The mean coronal angle for the implant was 80.19±17.13 degrees and the mean sagittal angle was 94.83±9.94 degrees. The septal height represents 38.13% of the total available bone height (ABH). The mean percentage of the septum used to insert the implants was 47.33±2.47%. The septum increased the available bone height by a mean value of 2.18±1.47 mm. In 45 cases, the septa did not permit implant placement. Conclusions In completely edentulous patients, inserting implants in sinus septa does not exclude the need for sinus grafting, but in partially edentulous patients, this minimally invasive technique is an alternative to subantral augmentation.

Although it was medical refractory, successfully treated with mechanical thrombectomy using the Solitaire FR device. A 27-year-old man who presented with venous infarction accompanied by petechial hemorrhage secondary to the superior sagittal sinus (SSS) thrombosis. Due to rapid deterioration despite of anticoagulation therapy, the patient was taken for endovascular treatment. We deployed the Solitaire FR device (4×20 mm) in the anterior portion of the thrombosed SSS, and it was left for ten minutes before the retraction. Thus, we removed a small amount of thrombus. But the sinus remained occluded. We therefore performed the thrombectomy using the same methods using the Solitaire FR (6×20 mm). Thus, we were successful in removing larger clots. Our case highlights not only that the mechanical thrombectomy using the Solitaire FR is effective in achieving revascularization both rapidly and efficiently available, but also that it might be another option in patients with cerebral venous sinus thrombosis who concurrently had rapid clinical deterioration with devastating consequences.

Due to rapid deterioration despite of anticoagulation therapy, the patient was taken for endovascular treatment. We deployed the Solitaire FR device (4×20 mm) in the anterior portion of the thrombosed SSS, and it was left for ten minutes before the retraction. Thus, we removed a small amount of thrombus. But the sinus remained occluded. We therefore performed the thrombectomy using the same methods using the Solitaire FR (6×20 mm). Thus, we were successful in removing larger clots. Our case highlights not only that the mechanical thrombectomy using the Solitaire FR is effective in achieving revascularization both rapidly and efficiently available, but also that it might be another option in patients with cerebral venous sinus thrombosis who concurrently had rapid clinical deterioration with devastating consequences.

    The condition of the maxillary sinus is not routinely assessed before a Le Fort I osteotomy. Performing this procedure in an infected sinus might account for a considerable proportion of the complications, such as excessive bleeding and sinusitis. The aim of this study was to evaluate the maxillary sinus and nasal ventilation after Le Fort I osteotomy. Twenty patients were evaluated before and 2 months after surgery using validated questionnaires for sinonasal complaints (RSOM-31 and VAS score), nasal endoscopy, peak nasal inspiratory flow (PNIF), and a computed tomography (CT) scan. There were no differences in complaints before and 2 months after surgery (P>0.24). Also, the PNIF did not change significantly (P=0.10). On CT evaluation before surgery, a previously unnoted sinusitis was diagnosed in two patients. Postoperatively, a thickened sinus mucosa was present in all patients near the osteotomy line, the osteosyntheses, and around sequesters. This report describes maxillary sinus evaluation after Le Fort I osteotomy in a more comprehensive way by using CT. The Le Fort I procedure did not influence already existing physical or mental complaints, and nasal ventilation was not negatively affected. However, evaluation of sinonasal pathology should be emphasized in the preoperative work-up.

    This article presents a case of bilateral ethmoid sinusitis with unilateral proptosis as a presenting sign of an unsuspected prostate carcinoma. A 59-year-old Hispanic male presented to his primary care physician with nasal congestion and rhinitis. He was treated with antibiotics and antihistamine decongestants for 3 weeks without improvement. A trial of steroids resulted in brief improvement followed by a rapid onset of nasal obstruction with proptosis. A computed tomography scan revealed opacification of the ethmoid sinus with right proptosis. The presumptive diagnosis was orbital cellulitis secondary to chronic ethmoid sinusitis. Endoscopic sinusotomy and bilateral ethmoidectomies were performed. Biopsy results returned as metastatic adenocarcinoma, probably of prostate origin. Urological work-up and evaluation with biopsy confirmed the diagnosis of prostatic carcinoma. The patient was treated with chemotherapy and radiation therapy. He died 7 months later with disseminated disease. Images Figure 1 Figure 2 Figure 3 Figure 4A Figure 4B PMID:7861473

    The aortic sinus vortex is a classical flow structure of significant importance to aortic valve dynamics and the initiation and progression of calcific aortic valve disease. We characterize the spatiotemporal characteristics of aortic sinus vortex dynamics in relation to the viscosity of blood analog solution as well as heart rate. High-resolution time-resolved (2 kHz) particle image velocimetry was conducted to capture 2D particle streak videos and 2D instantaneous velocity and streamlines along the sinus midplane using a physiological but rigid aorta model fitted with a porcine bioprosthetic heart valve. Blood analog fluids used include a water-glycerin mixture and saline to elucidate the sensitivity of vortex dynamics to viscosity. Experiments were conducted to record 10 heart beats for each combination of blood analog and heart rate condition. Results show that the topological characteristics of the velocity field vary in timescales as revealed using time bin-averaged vectors and corresponding instantaneous streamlines. There exist small timescale vortices and a large timescale main vortex. A key flow structure observed is the counter vortex at the upstream end of the sinus adjacent to the base (lower half) of the leaflet. The spatiotemporal complexity of vortex dynamics is shown to be profoundly influenced by strong leaflet flutter during systole with a peak frequency of 200 Hz and peak amplitude of 4 mm observed in the saline case. While fluid viscosity influences the length and timescales as well as the introduction of leaflet flutter, heart rate influences the formation of counter vortex at the upstream end of the sinus. Higher heart rates are shown to reduce the strength of the counter vortex that can greatly influence the directionality and strength of shear stresses along the base of the leaflet. This study demonstrates the impact of heart rate and blood analog viscosity on aortic sinus hemodynamics.

    2016-01-01

    Background: Recently, there has been tremendous interest in the sinus microbiome and how it relates to disease. However, a lack of a standardized sample collection and DNA extraction methods makes comparison of results across studies nearly impossible. Furthermore, current techniques fail to identify which components of the microbiome are actually alive within the host at the time of sampling. Objective: To develop and optimize a method to differentiate which bacterial species in the human sinus microbiome are live versus dead. Methods: Duplicate samples from the middle meatus of patients with healthy sinus tissue and those patients with chronic rhinosinusitis were collected by using brushes (n = 12), swabs (n = 27), and tissue biopsy (n = 8) methods. One sample from each pair was either deoxyribonuclease I- or control-treated before DNA extraction. The relative bacterial versus human composition of each sample was determined. A 16S ribosomal RNA gene analysis was performed on a six-paired sample from patients with healthy sinus tissue. Results: We found that swabs and brushes collected a higher percentage of bacterial DNA than did tissue biopsy. We also determined that as much as 50% of the bacteria collected in these samples was already dead at the time of collection. The 16S ribosomal RNA gene analysis found significant changes in the relative abundance of taxa identified in the live versus dead bacterial communities of healthy human sinuses. Conclusions: Our findings indicated that swabs provided the best quality microbiome samples and that a large portion of the bacteria identified in the sinus were deoxyribonuclease I sensitive. These results highlighted the need for improved techniques such as those presented here, which can differentiate between living and dead bacteria in a sample, a potentially critical distinction when examining changes in sinus innate immune function because both components play important, but distinct, functions.

    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.

    Inappropriate sinus tachycardia (IST) is a clinical syndrome lacking formal diagnostic criteria. It is generally defined as an elevated resting heart rate (HR; >90-100 bpm) with an exaggerated response to physical or emotional stress and a clearly sinus mechanism. Clinical manifestations are broad from a complete lack of symptoms to incapacitating incessant tachycardia. Now understood to be relatively prevalent, it is observed to have a generally benign prognosis, though symptoms may persist for years. Whether IST is a single discrete entity or a heterogeneous condition with overlap to other syndromes such as postural orthostatic tachycardia syndrome remains a matter of debate. PMID:26310298

    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

    Splenic sinuses in idiopathic portal hypertension (IPH; 8 patients), liver cirrhosis (LC; 14 patients) and in regenerating autotransplanted spleens from 25 rats were compared with each other by scanning electron microscopy (SEM) and immunohistochemistry using antibodies against proliferating cell nuclear antigen (PCNA). Spleens obtained from six patients with gastric carcinoma and from five untreated adult rats were examined as controls. SEM of the sinuses showed that in IPH endothelial cells became irregular in shape, and the interendothelial slits of sinuses were irregularly enlarged. Sinus endothelial processes traversing the sinusal lumen were also found. The same changes were observed in the proliferating sinuses during regeneration of splenic tissue after autotransplantation in rats, but disappeared when the regeneration was completed. Irregular endothelial cells were few in LC. PCNA-positive sinus endothelial cells were increased in number in IPH as compared with those in LC; the mean number of PCNA-positive ones per cm2 was 45.4 in IPH and 8.2 in LC. It was suggested that, from SEM observation of sinus endothelial cells and counting PCNA-positive sinus endothelial cells, the sinuses of the spleen in IPH consist of proliferating endothelial cells or are in the state of increased proliferation. In conclusion, splenomegaly in IPH was presumed to be caused by proliferation of sinus endothelial cells, and by the increased splenic blood flow in the irregularly widened interendothelial slits of the sinuses.

    Giant osteomas of the ethmoid and frontal sinuses ary very rare, with only a few dozen cases reported in the literature. Given their rarity, the clinical characteristics and treatment of this disease remain controversial. In this study, the clinical presentation and surgical methods used to treat three patients with giant osteomas of the ethmoid and frontal sinuses are described, combined with a review of the literature from 1975 to 2011. In total, 45 patients with giant osteomas arising from the ethmoid and frontal sinuses (including the present cases) have been reported in 41 articles. Headache and ocular signs are the most common symptoms. This disease often leads to intracranial or intraorbital complications. The main treatment for giant osteoma is surgery via an external approach. The outcome of surgery for giant osteoma is good, with rare recurrence, no malignant transformation and few persistent symptoms. PMID:23759920

    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.

We present a case of Graves disease, who suffered unilateral sigmoid and transverse sinus thrombosis with intracranial hemorrhage. A 42-year-old female, a diagnosed case of Graves disease, presented to us with headache, drowsiness, and hemiparesis. Computed Tomography revealed a large right temporo-parieto-occipital venous infarct. The patient needed surgical intervention in the form of decompressive craniotomy following which she improved, and on follow-up is having no deficits. Thrombophilia profile showed a low Protein S and Anti thrombin III (AT III) levels. Deranged thrombophilia profile in combination with the hypercoagulable state in thyrotoxicosis, most likely precipitated the thrombotic event. Timely surgical intervention can be offered in selective cases with a good clinical outcome. PMID:24403961

    We report the case of a pediatric patient in whom a spinal congenital dermal sinus was detected after the onset of anaerobic bacterial meningitis. The patient was a 4-month-old boy. He had a recurrent fever for 2 weeks before admission. On admission, he presented with a convulsive status and a bulging anterior fontanel. The previously consulted physician had made a diagnosis of bacterial meningitis. Spinal fluid cultures tested positive for Peptoniphilus asaccharolyticus. Magnetic resonance imaging (MRI) showed a spinal subdural abscess and cranial subdural hydrops; therefore, the patient was transported to our hospital for surgical treatment. A sacral dimple was noted on his lower back, and an MRI showed a spinal congenital dermal sinus. Antimicrobial therapy, cranial subdural aspiration, dermal sinus excision, and drainage were performed. He was discharged on the 60th hospital day. When pathogens such as Staphylococcus aureus or Escherichia coli, Proteus sp. or anaerobic bacteria invade through a dermal sinus, it can result in meningitis. Involvement of a dermal sinus should be suspected when meningitis is caused by these pathogens or when recurrent meningitis occurs. PMID:27529968

    Electrophysiological studies in 13 patients with thyrotoxicosis (5 men and 8 women, aged 17 to 76 years) are reported. Five patients presented with features of sick sinus syndrome (SSS) (Group A) while the remaining 8 patients (Group B) had no detectable cardiovascular abnormality. Sinus node function (corrected sinus node recovery and sinoatrial conduction time) was abnormal in all Group A but normal in Group B patients. Intra-atrial, artioventricular (AV) nodal, and infranodal conduction time and effective refractory period of atrium were normal in all patients in both groups. Effective refractory period of AV node was decreased in 6 patients (3 in each group). All Group A patients received radioiodine with complete clinical remission of sick sinus state in 4 subjects. Repeat electrophysiological studies in two of these patients, 6 and 12 months after treatment, showed complete normalization of sinus node function. This is the first reported electrophysiological study documenting the occurrence of SSS in thyrotoxicosis reversed by effective antithyroid treatment. We suggest that attempts should be made to identify underlying thyrotoxicosis in all patients with SSS, especially in the older age group. Appropriate medical treatment may prevent unnecessary implantation of permanent pacemakers in such patients.

    An osteoma within the paranasal sinuses is a rare benign fibro-osseous tumour. Osteomas occurring in the maxillary sinus are exceedingly rare and account for only 5% of the cases. A case of a 38-year-old female with an osteoma of the maxillary sinus is presented and the disease and its management are discussed. A 2 cm spherical lesion in her right maxillary sinus was picked up incidentally on a magnetic resonance imaging scan whilst being investigated for unrelated neurological symptoms and in the absence of any sinonasal symptoms. An endoscopic biopsy demonstrated that the mass was an osteoma. The management of paranasal sinus osteomas is surgical and is governed by patient symptoms, tumour size and location, in the light of the risk of future intracranial or intraorbital complications. The choice of surgical approach is determined by the location of the tumour and, the experience of the surgeon. In this case a combined external and endonasal approach was the most appropriate management due to the size of the tumour and the risk of intraorbital complications. The patient underwent a combined Caldwell-Luc and transnasal endoscopic resection without complication.

    Abstract Background: Primary small cell carcinomas (SCCs) are uncommon in extrapulmonary sites and account for only 2.5% to 5.0% of all SCCs. SCCs in the pyriform sinus are rare and there is little information regarding this disease, especially on therapeutics. Herein, we present a case of successfully treated SCC in the right pyriform sinus that occurred in a patient with small cell lung carcinoma (SCLC) that completely resolved 4 years prior. Methods: A 1.5 × 1.5-cm mass in the right pyriform sinus was detected on imaging studies in a 71-year-old male at a regular check-up visit after being in remission from SCLC. Results: Based on histologic examination and immunohistochemistry, the tumor in the right pyriform sinus was diagnosed as an extrapulmonary SCC. Chemo-radiotherapy was applied to the SCC of the pyriform sinus with a regimen of etoposide and cisplatin. The patient exhibited complete response to treatment and has been disease free for 11 months. Conclusion: This interesting case shows that chemotherapy with concurrent radiation may be an effective therapeutic modality for localized extrapulmonary SCC similar to localized SCLC, which is treated with concurrent chemo-radiotherapy as the standard therapeutic option.

    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.

    Acute frontal sinusitis can be a serious condition because of its potential life-threatening complications. These complications, including spread of infection to the frontal bone and intracranially, require prompt diagnosis and intervention to avoid morbidity and mortality. We report a case of acute frontal sinusitis in a 16-year-old girl who presented with fever, severe headache, and vomiting of 3 days' duration. Generalized fluctuant swelling of the nasal root, and bilateral supraorbital and frontoparietal regions was noted. Computed tomography (CT) demonstrated left pansinusitis, extensive subgaleal abscess and epidural empyema with osteomyelitis of the frontal bone. External frontoethmoidectomy with mucoperiostectomy were performed. Endoscopic sinus surgery was then conducted for intranasal ethmoidectomy. Intraoperative cultures grew viridans streptococci, coagulase-negative staphylococci and Peptostreptococcus micros. The patient received 3 weeks of treatment with intravenous antibiotics (penicillin 3 MU 4-hourly, ceftriaxone 500 mg 12-hourly, metronidazole 500 mg 6-hourly) and was discharged uneventfully and prescribed additional oral antibiotics for 5 weeks (clindamycin 150 mg 6-hourly and chloramphenicol 250 mg 6-hourly). CT revealed complete resolution of the abscess and clear maxillary and ethmoid sinuses at 7 weeks posttreatment. The patient was free of sinus infection at 4-years follow-up, without noticeable cosmetic deformity.

    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

    Abstract. 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. PMID:25781310

    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.

    The Spanish National Consensus (Spanish Society of Pediatric Infectious Diseases, Spanish Association of Primary Care Pediatrics, Spanish Society of Pediatric Outpatient and Primary Care, Spanish Society of Otorhinolaryngology and Cervical-Facial Pathology) on Sinusitis is presented. Rhinosinusitis is a difficult to diagnose and often unrecognised disease. The document discusses the aetiology, the clinical signs and symptoms, and the diagnostic criteria. A proposal for treatment is made based on the epidemiological situation in our country. Oral amoxicillin is the treatment of choice (80mg/kg/day divided every 8hours). Alternative treatment is proposed in special cases and when amoxicillin is not sufficient. The main complications are reviewed.

    An alert and oriented 27-year-old African American woman with AIDS presented with a 10-day history of fever, cough productive of yellow sputum, nausea, and vomiting and a 1-day history of excruciating headache and photophobia. Her condition rapidly deteriorated into a coma with decorticate and then decerebrate posture, and she died 3 weeks later. There was evidence of extensive intracranial venous sinus thrombosis (ICVST), renal vein thrombosis (RVT), and multiple cerebral hemorrhagic infarcts due to a hypercoagulable state complicating AIDS-associated nephrotic syndrome. This is the first reported case of fatal ICVST and RVT with extensive cerebral hemorrhagic infarcts complicating nephrotic syndrome in a patient with AIDS.

    Brucellosis is a commonly diagnosed zoonosis and neurological involvement is rare. A 30-year-old woman presented with a pulsatile headache that was exacerbated by the Valsalva maneuver and refractory to analgesic therapy. The patient also had nausea, cough, and coryza that evolved over 7 days. The neurological examination was unremarkable. Thrombosis of the lateral and sigmoid sinus and ipsilateral internal jugular vein were diagnosed and anticoagulation therapy was started. Brucella spp was identified in a sample of cerebrospinal fluid (CSF); five months after treatment with rifampicin and doxycycline, CSF was sterile. Cerebral venous thrombosis is a very uncommon sign of brucellosis. PMID:27384841

    Management of frontal sinusitis can be challenging for even the most experienced otolaryngologists. A thorough understanding of the anatomy and pathophysiology of the frontal sinus is essential to properly manage disease affecting the frontal sinus. Being able to distinguish acute viral from acute bacterial and acute from chronic sinusitis is crucial because these distinctions guide appropriate management. Nasal endoscopy can confirm diagnosis, and radiologic imaging, including computed tomography and MRI, is often a necessary adjunct that aids in determining appropriate therapeutic decisions. One must be aware of the many procedures used in the surgical treatment of frontal sinusitis. PMID:27450615

    Variants of the external osteoplastic flap procedure or endoscopy have been used to approach the frontal sinus mucocele. The authors introduce a modified external approach for radical resection of the mucocele. Using the bicoronal skin incision, the skin flap exposed the right upper orbital rim. The outer table craniotomy was then performed to expose the frontal sinus cavity while carefully preserving the inner table, with radical removal of the mucocele mucosa. The sinus cavity was irrigated with hyper-oxide solution to ensure adequate destruction of possible residual mucosa. The fascia of the frontalis muscle was split, with one part placed into the mucocele cavity to plug the nasofrontal duct. The advantages of the procedures for mucocele removal include clear visualization of the frontal sinus for radical resection of the mucosa, preservation of the inner table avoiding dura manipulation, prevention of central nervous system infection, possibly lower rates of recurrence, prevention of mucosal ingrowth by plugging of the nasofrontal ducts with fascia, and favorable cosmetic outcome. The disadvantages are more intensive surgery comparable to the endoscopic approaches and execution difficulties when the frontal mucocele is small. Additional clinical studies are needed to evaluate the efficiency and safety of this procedure.

    We have observed two contiguous mucoceles in one patient. Based on the mucoceles' signal intensities on MR imaging, as well as their anatomic location as delineated by CT and MR, we hypothesize that the "downstream" mucocele obstructed the "upstream" sinus, leading to formation of a secondary mucocele.

    Measurement of the sinus node recovery time has been proposed as a diagnostic tool for recognition of the sick sinus syndrome. The latter is most frequently encountered in elderly patients with hypertension, coronary heart disease, and atherosclerosis. In order to provide normal values for the sinus node recovery time in this particular population group, atrial pacing studies were carried out in 30 subjects over 50 years of age, all with peripheral vascular disease and some with angina pectoris (10), residua of infarction (6), or hypertension (7). On stimulation, 7 patients maintained a I:I atrioventricular conduction up to the rate of 180/min. Second degree atrioventricular block developed in all other cases. On six occasions, Wenckebach's periods appeared at the relatively slow pacing rate of 120/min. The maximum postoverdrive pause ranged from 680 to 1600 ms with an average of 1100 ms plus or minus 190 (10). For each pacing speed, a correlation was found between the duration of the pause and the control intrinsic cardiac rate, longer pauses being associated with longer resting PP intervals. Beyond 120/min, the duration of the pause was seen to shorten progressively as the driving rate was increased. Finally, the behavior of the sinus node pacemaker following interruption of pacing showed individual variations. After pacing at relatively slow rates, a prompt return to near control values was consistently observed, whereas, after fast rates of driving, a phase of secondary depression developed in about one-half of the studied cases.

    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

    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.

    Electrophysiologic studies were performed in 10 normals and 33 patients with sick sinus syndrome before and after total autonomic blockade with propranolol and atropine. In normals both corrected sinus node recovery time (SNRT) and sinoatrial conduction time (SACT) decreased significantly after autonomic blockade. In patients with sick sinus syndrome the corrected SNRT was abnormal (greater than 450 msec) in 16 (48.5%) cases before and 25 (76%) cases (greater than 285 msec) after autonomic ablation (P less than 0.02). Thirteen of 21 patients (62%) with normal intrinsic heart rate and all 12 cases with abnormally low intrinsic rate after autonomic blockade had abnormal corrected SNRT (greater than 285 msec). Mean SACT measured in 19 patients also shortened significantly following pharmacologic denervation. During control it was prolonged (greater than 226 msec) in 8 patients (44%). After autonomic blockade 2 of 13 patients with normal intrinsic heart rate and 3 of 6 with low intrinsic rate showed abnormal SACT (greater than 151 msec). The data suggest that the majority (76%) of patients with sick sinus syndrome have intrinsic abnormality of sinus node automaticity while in a minority (24%) disturbed autonomic regulation is the pathogenetic mechanism. Patients with normal intrinsic heart rate usually have normal intrinsic SACT, while a significant proportion of those with low intrinsic rate have abnormal perinodal conduction. Subjects with abnormal intrinsic heart rate have more severe disturbances of sinus node function than those with normal intrinsic rate.

    Sinus-node recovery times were measured, before and after atropine administration, in 21 patients with the clinical diagnosis of sick-sinus syndrome. The results were compared with those reported by other workers. It is concluded that sinus-node recovery times of more than 1 400 ms are most likely due to sinus-node damage (sick-sinus syndrome); normal recovery times are rare in such patients. The diagnosis of the syndrome is strengthened if the recovery time remains abnormally long even after atropine. Further useful diagnostic information can be obtained from the total stimulation phase (duration until restoration of the basic rhythm), this being overall longer in patients with the syndrome than in normal subjects. The increased incidence of A-V nodal rhythms before restoration of the basic rhythm is another indication of organic damage to the sinus node, especially if it also occurs after atropine. The significance of a recovery time which is prolonged before but normal after atropine is less clear: a raised sensitivity to vagotonic influences may be the determining factor here.

    One of the most widely used tests for evaluation of sinus node function is sinus node recovery time (SNRT), which requires right heart catheterization. On the other hand SNRT has high specificity but only moderate sensitivity in the diagnosis of sick sinus syndrome (SSS). The authors studied acute electrophysiologic effects of dipyridamole (0.40 mg/kg IV) in 16 patients with clinical SSS. All of them had normal SNRT and had undergone permanent DDD pacemaker implantation. By the aid of temporary pacing inhibition, the authors noninvasively measured the corrected sinus node recovery time (SNRTc) and sinus cycle length (SCL) before and after dipyridamole administration. SCL was slightly decreased from a mean basal value of 1025 +/-323 to 913+/-213 msec after dipyridamole administration (mean -10%), but this was not statistically significant. SNRTc was increased from a mean basal value of 344+/-91 to 606+/-156 msec after dipyridamole administration (+76% P< or =0.004). These results suggest that dipyridamole must be used cautiously in patients with SSS. Intravenous dipyridamole may be a useful test to assess sinus node function. SNRT measurement after intravenous dipyridamole may increase sensitivity of this test in patients with suspected SSS and normal SNRT.

    Coronary sinus atrial septal defects are the rarest defects of the atrial septum comprising <1% of the five different types of atrial septal defects. Despite the widespread adoption of percutaneous device closure of secundum atrial septal defects, the published experience with percutaneous device closure of coronary sinus atrial septal defects is limited to only a few isolated case reports because of uncertainty regarding safety and efficacy. Open-heart surgical repair remains the treatment of choice for coronary sinus atrial septal defects, although this may not be the only treatment option in selected cases. Herein we describe our own experience with two patients with different clinical presentations and our method of successful percutaneous coronary sinus atrial septal defect closure in each. We then present a review of the anatomic spectrum of coronary sinus atrial septal defects along with a review of contemporary surgical and percutaneous device treatment. PMID:24666783

    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

    Summary The maxillary sinus elevation is a standard and predictable procedure allowing the realization of dental implant rehabilitation in patients with severe bone atrophy in the lateral-posterior areas of the maxilla. Despite the presence of validated surgical methods and the broad availability of biomaterials, the procedures aimed at increasing the bone volume by lateral antrostomy still entail complications with different degrees of relevance. The prosthetic and surgical outcome is based on a successful coping with these aspects. The perforation of the Schneiderian membrane is one of the most frequent events for which a variety of protocols and approaches have been suggested by different authors. In this work is presented a case study in which a technique to repair the sinus mucosa laceration occurring during a maxillary sinus elevation procedure has been successfully adopted. PMID:22783452

    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

    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

    The present paper compares the use of the microdebrider as a form of powered instrumentation for endoscopic sinus surgery with traditional endoscopic surgical techniques. A group of 250 patients undergoing surgery with the microdebrider was compared with a group of 225 patients undergoing traditional procedures in order to evaluate their postoperative recovery, healing, and incidence of complications. The use of the microdebrider demonstrated faster healing with less crusting than standard techniques, as well as decreased bleeding, synechia formation, lateralization of the middle turbinate, and ostial reocclusion. The microdebrider offers excellent surgical results with fewer complications and faster healing than traditional techniques in functional endoscopic sinus surgery.

    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.

    Percutaneous transcatheter closure of ruptured sinus of valsalva aneurysm was attempted in eight patients between January 1995 and March 2003 as an alternative strategy to surgery as this technique at present is an accepted therapeutic modality for various intracardiac defects. The age range was 14-35 years, all were male, seven in symptomatic class III and one in class IV on medical treatment. Two-dimensional and color Doppler echocardiography revealed rupture of an aneurysm of right coronary sinus into right ventricle in five and noncoronary sinus into right atrium in three and none had associated ventricular septal defect. The echo estimated size of the defect was 7-12 mm. On cardiac catheterization left ventricular end-diastolic pressure ranged from 20 to 40 mmHg and the calculated Qp/Qs ratio was 2-3.5. In all patients the defect was crossed retrogradely from the aortic side and over an arterio-venous wire loop after balloon sizing, devices were successfully deployed by antegrade venous approach (Rashkind umbrella device in two and Amplatzer occluders in six, which included Amplatzer duct occluder in five and Amplatzer septal occluder in one). One patient who had residual shunt developed hemolysis on the next day and was taken up for reintervention. That patient continued to have intermittent hemolysis and was sent for surgical repair. On follow-up (2-96 months), there was no device embolization, infective endocarditis, and aortic regurgitation. One patient died of progressive congestive heart failure while other six are asymptomatic. These data highlight that transcatheter closure is feasible and effective, especially safe with the available Amplatzer devices. Definitely, it has the advantage of obviating open heart surgery but complete occlusion is mandatory to prevent hemolysis and infective endocarditis. PMID:15009772

    Background Functional endoscopic sinus surgery (FESS) was historically predicated on targeted widening of narrow anatomic structures that caused post-obstructive persistent sinus inflammation. It is now clear that chronic rhinosinusitis (CRS) is a multi-factorial disease with subsets of patients which may require a more extensive surgical approach. This study compares quality-of-life (QOL) and disease severity outcomes after FESS based on the extent of surgical intervention. Methods Participants with CRS were prospectively enrolled into an on-going, multi-institutional, observational, cohort study. Surgical extent was determined by physician discretion. Participants undergoing bilateral frontal sinusotomy, ethmoidectomy, maxillary antrostomy, and sphenoidotomy were considered to have undergone ‘complete’ surgery, while all other participants were categorized as receiving ‘targeted’ surgery. Improvement was evaluated between surgical subgroups with at least 6-month follow-up using the 22-item Sinonasal Outcome Test (SNOT-22) and the Brief Smell Inventory Test (BSIT). Results 311 participants met inclusion criteria with 147 subjects undergoing complete surgery and 164 targeted surgery. A higher prevalence of asthma, ASA sensitivity, nasal polyposis, and a history of prior sinus surgery (p≤0.002) was present in participants undergoing complete surgery. Mean improvement in SNOT-22 (28.1[21.9] vs. 21.9[20.6];p=0.011) and BSIT (0.8[3.1] vs 0.2[2.4];p=0.005) was greater in subjects undergoing complete surgery. Regression models demonstrated a 5.9[2.5] greater relative mean improvement on SNOT-22 total scores with complete surgery over targeted approaches (p=0.016). Conclusions Complete surgery was an independent predictor of greater postoperative SNOT-22 score improvement, yet did not achieve clinical significance. Further study is needed to determine the optimal surgical extent. PMID:25907972

    Ten patients with sick sinus syndrome having repetitive sinus node electrograms during long postpacing pauses were studied during programmed atrial stimulation. Sinus node activity was recorded using a percutaneous catheter electrode. A sinus node electrogram was recorded before the return atrial beat in seven patients; it was similar to the sinus node electrogram observed during postpacing pauses and is clearly identified because sinoatrial conduction time was markedly prolonged following the atrial extra beat. Complete sinoatrial exit block occurred in four patients. (1) Sinus node electrograms were thus validated both during postpacing pauses and during programmed atrial stimulation in most patients with sick sinus syndrome. (2) Sinoatrial conduction time was markedly prolonged after one extrasystole, accounting for supracompensatory atrial return cycles. (3) If it were cumulative following multiple extrasystoles, this effect could constitute the electrophysiologic link between an abnormal response during programmed atrial stimulation and the complete sinoatrial block recorded during the pauses that follow rapid atrial pacing.

    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. PMID:26396628

    Maxillary sinus membrane perforation has been reported as the most common intraoperative complication during sinus augmentation, potentially leading to postoperative infection and consequent loss of graft or even implant failure. Numerous anatomical factors have been demonstrated to affect membrane tearing. However, careful use of proper instrumentation, such as a reamer, seems to play an important role in minimizing the incidence of these complications. Hence, the aim of the present study was to (1) investigate the reliability of reamer drilling for lateral window preparation; (2) examine the incidence of membrane perforation; and (3) study the factors that might influence membrane perforation. Results from this study showed the safety and effectiveness of using a reamer to perform lateral window approach sinus augmentation. The sinus membrane perforation rate was found to be 12.5%. A slightly higher perforation rate was noted in thinner maxillary lateral walls (< 1.25 mm). The authors concluded that reamer drilling is a safe and effective alternate technique for opening the lateral window wall when the lateral wall thickness is ≥ 1.25mm.

    OBJECTIVE Accurate knowledge of the anatomy of the straight sinus (SS) is relevant for surgical purposes. During one surgical procedure involving the removal of part of the SS wall, the authors observed that the venous blood flow was maintained in the SS, possibly through a vein-like structure within the dural sinus or dural multiple layers. This observation and its divergence from descriptions of the histological features of the SS walls motivated the present study. The authors aimed to investigate whether it is possible to dissect the SS walls while keeping the lumen intact, and to describe the histological and ultrastructural composition of the SS wall. METHODS A total of 22 cadaveric specimens were used. The SS was divided into three portions: anterior, middle, and posterior. The characteristics of the SS walls were analyzed, and the feasibility of dissecting them while keeping the SS lumen intact was assessed. The thickness and the number of collagen fibers and other tissues in the SS walls were compared with the same variables in other venous sinuses. Masson's trichrome and Verhoeff's stains were used to assess collagen and elastic fibers, respectively. The data were analyzed using Zeiss image analysis software (KS400). RESULTS A vein-like structure independent of the SS walls was found in at least one of the portions of the SS in 8 of 22 samples (36.36%). The inferior wall could be delaminated in at least one portion in 21 of 22 samples (95.45%), whereas the lateral walls could seldom be delaminated. The inferior wall of the SS was thicker (p < 0.05) and exhibited less collagen and greater amounts of other tissues-including elastic fibers, connective tissue, blood vessels, and nerve fibers (p < 0.05)-compared with the lateral walls. Transmission electron microscopy revealed the presence of muscle fibers at a level deeper than that of the subendothelial connective tissue in the inferior wall of the SS, extending from its junction with the great cerebral vein

    Objective: To explore the correlationship between brady sinus arrhythmia and the levels of serum klotho protein in aged. Methods: 104 patients over 75 years old with brady sinus arrhythmia (experiment group) were enrolled, including 34 cases of sinus arrest, 43 cases of sinus bradycardia and 25 cases of atrioventricular block. 109 patients over 75 years old without brady sinus arrhymia were chosen as control group. All subjects were monitored by Holter. The levels of serum klotho protein were detected and compared among three groups. The correlation between the frequency of sinus arrest and the levels of serum klotho protein was analyzed simultaneously. Results: The levels of serum klotho protein in experiment group were lower than that in control group (P<0.01); the sinus arrest frequency was negatively correlated with the levels of serum klotho protien. The levels of serum klotho protein in patients with sinus arrest were lower than that with sinus bradycardia and atrioventricularblock (P<0.05). But there was no significant difference between sinus bradycardia group and atrioventricular block group. Conclusion: The levels of serum klotho protein may reflect the function of sinoatrial node and could be used as an index to estimate the function of sinoatrial node. PMID:26550342

    The records of 37 patients with lymphoma of the nose and paranasal sinuses in an 18-year period were studied. The symptoms were divided into three categories: (1) local symptoms: obstruction, bleeding, and rhinorrhea; (2) symptoms of invasion of adjacent structures: facial pain and ear fullness; and (3) systemic symptoms: fever, weight loss, and nocturnal sweating. The presence of an intranasal mass was the most common physical finding. Conventional tomography and computed tomography were helpful for diagnosis. Abnormalities were usually disclosed on biopsy specimens from the nose or mouth. As a rule, several sites in the nose and sinuses were involved. An early diagnosis of sinonasal lymphoma and other malignant neoplasms generally allows effective treatment; therefore, the otorhinolaryngologist should be alert for such disease and, if the clinical picture warrants, should add tomography to the diagnostic workup.

    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

    Pilonidal sinuses (PS) predominantly affect young male adults, usually occurring in the sacrococcygeal region. However, PS occasionally occurs in other parts of the body, referred to as extrasacrococcygeal pilonidal sinus (ESPS). We herein evaluate ESPS ethiopathogenesis and treatment. Of a total of 949 PS cases treated between 2006 and 2011, 21 were of ESPS (2.2% of the total), which were evaluated retrospectively. The affected regions were the breast (n = 1), scalp (n = 2), sternum (n = 2), abdominal wall (n = 5), neck (n = 2), groin (n = 4), and axilla (n = 5). Lesions of the abdominal wall are rare, but less so than lesions in other regions. PS may mimic hidradenitis suppurativa histologically. To our knowledge, PS of the breast and groin have not previously been reported. Twelve of our patients reported shaving the affected region; we suggest this may have played a role in the disease pathogenesis. PMID:26379983

    SUMMARY Purpose A novel technique for transcrestal guided sinus lift elevation (TGSL), is described underlining the step by step surgical protocol. Materials and methods TGSL modified osteotome technique was planned by the NobelProcera® Software Planning Programm (Nobel Guide, Nobel Biocare AB) and performed by stereolitographic template. The depth of the planned osteotomy was determined precisely via cross-sectional images of the elevation site to facilitate puncture of the bony sinus floor without risk of perforation of the adherent sinus membrane. A customized drilling-osteotome protocol is used to raise the Schneiderian membrane to the final implant length. Results The sinus membrane is successfully elevated in all sites without any iatrogenic perforation. Conclusions The TGSL modified osteotome technique may provide a new option for minimally invasive transcrestal sinus surgery and may represent a safe method to increase bone volume in the atrophic posterior maxilla. The results of the present study would suggest that this new surgical technique may reduce patient morbidity and extend the indications for transcrestal maxillary sinus floor elevation.

    Immediate treatment of this patient, evaluation of the wound, the use of antibiotics, and eventual reconstruction are all concerns in this complicated gunshot wound to the frontal sinus. The consultants agree that the first priority in this patient is to assess and stabilize the airway, examine the wound, and obtain a CT scan to ascertain the extent of the defect. Dr. Key feels that these wounds are contaminated and would prophylactically order a broad-spectrum cephalosporin and/or chloramphenicol. Dr. Tami would use antibiotics aimed at Staphylococcus and oral flora; Dr. Donald prefers to treat specific infections as they develop. They also agree that initial reconstruction should be conservative, aimed at covering exposed bone and minimizing local/regional flaps; however, Dr. Donald suggests using an arch bar on the intact side and eyelet wires on the injured side to address the maxillary defect. Drs. Key and Donald feel that it was a mistake to close this wound primarily and use a skin graft, because there was an inadequate soft tissue bed. Dr. Tami states that the initial management of the wound was reasonable. All agree on a basic approach to frontal sinus fractures. CT scanning is the imaging modality of choice. Nondisplaced fractures may be observed. Disruption of the posterior wall or the nasofrontal duct usually require exploration and obliteration of the sinus. Dr. Key would ablate the sinus only in cases where the anterior table is completely lost. Drs. Tami and Donald agree that cranialization should be reserved for comminuted posterior table fractures. After recognizing a CSF leak, Dr. Key would begin a broad-spectrum antibiotic.(ABSTRACT TRUNCATED AT 250 WORDS)

    Context: Many reconstructive techniques have been proposed to prevent postoperative cerebrospinal fluid (CSF) leakage after trans-sphenoidal pituitary surgery. However, no total agreement has been reached to the best technique. Aim: Assessment of the efficacy of sellar repair with autologous muscle and composite septal cartilage grafts for treatment of intraoperative and delayed postoperative CSF leakage following trans-sphenoidal pituitary surgery without the use of postoperative external lumbar CSF drain. Study Design: This is a retrospective case series study, level IV evidence. Materials and Methods : Twenty three patients were involved in this study. Seventeen patients had intraoperative CSF leakage and were treated immediately by our technique. Six patients had postoperative CSF rhinorrhea and had delayed treatment with our technique after failure of conservative measures and external lumbar CSF drainage for more than three days. The technique involved intradural placement of autologous muscle graft supplemented with extradural composite septal cartilage graft, composed of a piece of the posterior cartilaginous septum with its covering mucoperichondrium on one side only to fit into the sellar defect as a double layer button. Results: CSF leak was of grade 1 in 6 patients (26.1%), grade 2 in 10 patients (43.5%) and grade 3 in 7 patients (30.4%). None of the patients in our study had postoperative CSF leak after the use of our technique during the follow up period (mean 24 ± 10.47 standard deviation months). None of the patients developed treatment-related complications. All the patients had well developed mucosal covering of the sellar defect after two months. Conclusion: Our technique of sellar repair by using autologous muscle and composite septal cartilage grafts is effective in treatment of intraoperative and delayed postoperative CSF leakage following trans-sphenoidal pituitary surgery without the use of postoperative external lumbar CSF drain even in

    2004-12-01

    Forensic pathologists may be asked to identify the ethnic group and gender of a cranium of unknown origin. An analysis of the maxillary sinus--its volume, shape, and dimensions in dried crania of different ethnic and gender groups (European and Zulu male and female)--was conducted to establish a new approach. A variation in maxillary sinus volume may mean a variation in anatomic landmarks between the groups. Ethnic and gender variations in the shape of the maxillary sinus of the crania were investigated. This research was further extended to predict the gender and ethnic group from an unknown cranium to make this research valuable to the fields of forensic pathology and anthropology. Helical, multislice computed tomography was performed using 1-mm coronal slices. The area for each slice was obtained by tracing the outline of each slice. The computed tomographic machine calculated a volume by totalling the slices for each sinus. Advanced computer methodology including a neural network was designed and applied to search for classification patterns in data. A discriminant analysis was performed to improve classification results. Ethnic and gender variations were found in the different groups, and the predictive role of the maxillary sinus in ethnic classification was established. It was found that European crania had significantly larger antral volumes than Zulu crania, and males had larger volumes than females. Dimensions of European sinuses were larger than those of Zulu sinuses. The medial antral wall of the sinus allowed for ethnic classification. The discriminant analysis allowed for a very successful 90% ethnic prediction, while gender prediction was ultimately 79%. The measurements taken and the formulae created in this research will be valuable to those in the field who are seeking to ethnically classify a cranium into one or another ethic group. This research aims to be an aid in identification, as well as a starting point for other scientific studies based

    Solitary fibrous tumors (SFT) are uncommon neoplasm that arises in most cases from the pleura. SFT has been rarely observed in the head and neck, but SFT of the paranasal sinuses is especially rare, with 39 previously reported cases to date including those reported in this abstract. Herein we describe three cases of SFT in the paranasal sinuses that were successfully treated endoscopically. Two of the three cases involved patients with no previous history of SFT. The lesion of one of the patients was pathologically diagnosed as SFT preoperatively, but the other was diagnosed as an angiogenic tumor without any biopsies. The tumors were completely resected after arterial embolization by a transnasal endoscopic procedure. The third case involved a 43-year old man, who had undergone medial maxillectomy through a lateral rhinotomy incision to resect SFT four years and seven months before. The tumor relapsed intracranially and, therefore, a craniotomy procedure followed by endoscopic skull base surgery was performed. Radiation therapy was performed postoperatively because the recurrent tumor was pathologically identified as malignant SFT, which had been classified benign at the time of the first resection. All three patients are presently alive with no evidence of disease. PMID:26427128

    A 20-year-old female, university student presented with severe, throbbing, unilateral headache, nausea and vomiting that started 2 days ago. The pain was aggravated with physical activity and she had photophobia. She had been taking contraceptive pills due to polycystic ovary for 3 months. Cranial computed tomography was uninformative and she was considered to have the first attack of migraine. She did not benefit from triptan treatment and as the duration of pain exceeded 72 h further imaging was done. Cranial MRI and MR venography revealed a central filling defect and lack of flow in the left sigmoid sinus caused by venous sinus thrombosis. In search for precipitating factors besides the use of contraceptive pills, plasma protein C activity was found to be depressed (42%, normal 70-140%), homocystein was minimally elevated (12.7 μmol/L, normal 0-12 μmol/L) and anti-cardiolipin IgM antibody was close to the upper limit.

    We present the case of 9 year old male referred to the A and E service with right ocular proptosis and progressive migraine in the context of a sinusitis diagnosed two days earlier by compatible clinical and radiological tests, and receiving treatment with amoxicillin-clavulanic acid. Physcial exploration revealed right ocular proptosis with a slight limitation for conjugate gaze. Facing the suspicion of a possible neurological complication of the sinusitis, cranial computer aided tomography (CAT) was carried out, with right frontal subdural empyema observed. He was admitted for intravenous antibiotic treatment with cefotaxime, vancomicin and metronidazole. He was evaluated by child Neurosurgery, Maxillofacial Surgery and Otorhinolaryngology (ORL) services; the decision was taken to only drain the primary focus, while an expectant neurosurgical attitude was maintained. The patient evolved favourably with a progressive disappearance of the symptoms. Periodical magnetic resonances were carried out, which showed a clear improvement up until the complete resolution of the empyema. Following four weeks of antibiotherapy iv., and after clinical and radiological normalization, the patient was discharged.

    Sinus histiocytosis with massive lymphadenopathy (SHML) was recognized as a new clinical-pathological entity in 1969. Up to the present 134 cases have been described. The disease is characterized by prominent cervical lymph node enlargment. Microscopic features include marked dilatation of sinuses with intrasinusal histiocytes and lymphophagocytosis. About 70% of the patients reported were affected during the first 2 decades of life. The disease is held to be benign on account of spontaneous resolution in some patients. A follow-up survey of 72 patients showed disappearance of the symptoms 10 years after the original diagnosis in 24 patients. In 42 patients the disease still persisted 6 months to 21 years later. Six patients died, but only one of them as a result of the disease. Extranodal involvement was seen in the orbit, eyelid, respiratory tract, skin, bone, salivary glands, and testis. In two cases, one of which will be reported here, paraparesis resulted from infiltration of the epidural space. Treatment with prednisolone was tried in some cases with excellent results. In our case treatment with prednisolone and vinblastine resulted in the disappearance of the neurological symptoms.

    The present report describes a 54-year-old woman with cavernous sinus thrombosis (CST) presenting with fever, and marked periorbital swelling. There is a history of untreated periodontal disease. On initial examination, periorbital pain associated with bilateral blephaloptosis, chemosis, and disturbed eye movement was present. The laboratory evaluation showed significant elevations in inflammatory and fibrinolytic markers. Diffusion-weighted MRI revealed high signal intensities in the bilateral superior ophthalmic veins (SOV). Contrast-enhanced computed tomography (CT) of the cranium showed an enlarged right SOV and a non-enhancing lesion within the right SOV and bilateral cavernous sinus, indicating cavernous sinus thrombosis with diffuse SOV thrombosis. Blood culture performed on admission showed bacterial infection by intraoral resident flora; therefore, the CST was attributed to untreated periodontal disease. Contrast-enhanced CT of the case also revealed the presence of thrombosis in the jugular vein associated with micropulmonary embolus, indicating co-occurrence of Lemierre's syndrome. Antibiotic and anticoagulant treatment were initiated, and the tooth decay was treated; all clinical symptoms and signs subsequently improved. Additional neuroimaging showed that the thrombus was absent from both SOV and the cavernous sinus. Infectious CST is life threatening; therefore, laboratory and imaging examination should be performed quickly, and antibiotic and anticoagulant therapy administrated immediately. PMID:26041393

    The maxillary sinus is the largest paranasal sinuses. Foreign bodies of nosal sinus can caused by car accidents, firearm attacks, or iatrogeniccause. We reported two rare cases of foreign body of pulp needle and loach. The clinical manifestations might include facial numbness, facial paresthesia, swelling, nasal congestion, facial pain, eye discomfort, limited mouth opening and relapse and etc. Both CT scan and the medical history were helpful in diagnosis. Functional endoscopic surgery would be the first choice of treatment. PMID:26911073

    Pilonidal sinus is a chronic inflammatory disease commonly observed in the sacrococcygeal region. The authors report a patient of a pilonidal sinus in a rare location-the lateral orbital region. The authors' patient was misdiagnosed with an epidermal cyst, and the subsequent incomplete excision of the sinus tract led a pilonidal sinus with a high morbidity resulting in the destruction of bone tissue in the lateral orbital wall. It was, therefore, crucial to accurately diagnose and treat before the infection progressed through the bone and caused osteomyelitis. PMID:27391513

    Fungal infections of the nose and paranasal sinuses are uncommon, and the disease they cause can be identified from their histopathologic appearance. The aim of this study was to assess the incidence of fungal infection and histopathologic changes in specimens sent for evaluation of chronic sinusitis and correlate with culture findings wherever possible. The records of 200 consecutive cases coded as paranasal sinuses over a period of 3 years were retrieved from the Department of Pathology, Kasturba Medical College, Mangalore, India. Twenty nine out of a total of 200 specimens (14.5%) were positive for fungal elements on histopathologic examination. The most common etiologic agents in our study were Aspergillus spp (37.9%); only 1 culture (3.4%) was positive for a Candida species. Eight of 29 patients with fungal sinusitis (27.6%) had diabetes, and 1 patient was being treated for rheumatoid arthritis. Eight of the 29 patients had allergic fungal sinusitis, 8 had chronic granulomatous sinusitis, and 1 had acute fulminant invasive sinusitis. Fungi have been increasingly recognized as an important pathogen in chronic sinusitis. It is imperative for patient management not only that paranasal sinus mycoses be diagnosed but also that the specific histologic category be identified.

    A 23-year-old man sustained a gunshot wound to the posterior head. Imaging demonstrated a transection of the right transverse sinus, a retained bullet fragment and significant cerebellar oedema. The patient emergently underwent suboccipital decompression associated with brisk bleeding from the transverse sinus. Reported examples of surgical management of cerebral venous sinuses include: packing, grafting, patching and ligation. Our patient had a codominant transverse sinus and underwent successful unilateral ligation. His postoperative course was uneventful, however, he did require a ventriculoperitoneal shunt.

    Introduction To date intracranial complication caused by tooth extractions are extremely rare. In particular parietal subdural empyema of odontogenic origin has not been described. A literature review is presented here to emphasize the extreme rarity of this clinical entity. Case presentation An 18-year-old Caucasian man with a history of dental extraction developed dysarthria, lethargy, purulent rhinorrhea, and fever. A computed tomography scan demonstrated extensive sinusitis involving maxillary sinus, anterior ethmoid and frontal sinus on the left side and a subdural fluid collection in the temporal-parietal site on the same side. He underwent vancomycin, metronidazole and meropenem therapy, and subsequently left maxillary antrostomy, and frontal and maxillary sinuses toilette by an open approach. The last clinical control done after 3 months showed a regression of all symptoms. Conclusions The occurrence of subdural empyema is an uncommon but possible sequela of a complicated tooth extraction. A multidisciplinary approach involving otolaryngologist, neurosurgeons, clinical microbiologist, and neuroradiologist is essential. Antibiotic therapy with surgical approach is the gold standard treatment. PMID:25146384

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.

    The aim of the present study was to evaluate the effect of the association between the implant apex and the sinus floor in posterior maxilla dental implantation by means of three-dimensional (3D) finite element (FE) analysis. Ten 3D FE models of a posterior maxillary region with a sinus membrane and different heights of alveolar ridge with different thicknesses of sinus floor cortical bone were constructed according to anatomical data of the sinus area. Six models were constructed with the same thickness of crestal cortical bone and a 1-mm thick sinus floor cortical bone, but differing heights of alveolar ridge (between 10 and 14 mm). The four models of the second group were similar (11-mm-high alveolar ridge and 1-mm-thick crestal cortical bone) but with a changing thickness of sinus floor cortical bone (between 0.5 and 2.0 mm). The standard implant model based on the Nobel Biocare® implant system was created by computer-aided design (CAD) software and assembled into the models. The materials were assumed to be isotropic and linearly elastic. An inclined force of 129 N was applied. The maximum von Mises stress, stress distribution, implant displacement and resonance frequencies were calculated using CAD software. The von Mises stress was concentrated on the surface of the crestal cortical bone around the implant neck with the exception of that for the bicortical implantation. For immediate loading, when the implant apex broke into or through the sinus cortical bone, the maximum displacements of the implant, particularly at the implant apex, were smaller than those in the other groups. With increasing depth of the implant apex in the sinus floor cortical bone, the maximum displacements decreased and the implant axial resonance frequencies presented a linear upward tendency, but buccolingual resonance frequencies were hardly affected. This FE study on the association between implant apex and sinus floor showed that having the implant apex in contact with, piercing

    Osteoma is an osteoblastic benign tumor characterized by the proliferation of either compact or cancellous bone. In the jaws, the most of cases reported in the literature presented as peripheral solitary lesions, involving preferably the posterior region of the mandible. However, central osteomas are quite rare, especially in the maxillary bone. The purpose of this article was to present the clinical, radiographic, surgical, and histologic features of a solitary central osteoma of the maxilla with involvement of the paranasal sinus and to review the literature for central osteomas located in the jaws. Our clinical report participates to literature as the 12th case of central osteoma in the jaws and the fourth case in the maxillary bone.

    Basal cell adenoma (BCA) is a rare basaloid tumor, with only 20% of cases occurring in minor salivary glands. Histologically, BCA is characterized by the presence of basaloid cells and may frequently be mistaken with canalicular adenoma, basal cell adenocarcinoma, adenoid cystic carcinoma and basaloid squamous cell carcinoma. Immunohistochemistry may aid in arriving at a final diagnosis as in the present case. Reported here is a case of locally aggressive BCA. Histologically, the lesion mimicked ameloblastoma and other entities which posed a diagnostic challenge. There are no reports of BCA presenting as an aggressive lesion available in English literature so far; moreover, merely a single case of BCA of maxillary sinus has been previously reported to the best of our cognition. This case report highlights the rarity of this tumor with regards to its site of origin, clinical behavior and histopathological mimics. PMID:27194878

    The aim of this study was to explore the mechanism of racemic higenamine in the treatment of sick sinus syndrome (SSS). A total of 40 New Zealand rabbits were randomly divided into normal sinus node and damaged sinus node (SND) groups, and each group was randomly divided into treatment and control groups (n=10). The SND model was established by formaldehyde wet dressing of the sinus node area. The treatment groups were administered an intravenous infusion of 0.04 mg/kg racemic higenamine via the marginal ear vein within 5 min. The electrophysiological indicators of sinoatrial function, including the sinus node recovery time (SNRT), corrected sinus node recovery time (CSNRT), total sinoatrial conduction time (TSACT) and sinus cycle length (SCL), were determined before and 20 min after medication and the changes in these indicators were evaluated. The two control groups were administered 10 ml physiological saline. Following the administration of racemic higenamine, the SNRT, CSNRT, TSACT and SCL in the normal sinus node and SND groups were significantly shortened compared with those in the control groups (P<0.01). The electrophysiological influence of racemic higenamine on sinoatrial function in the SND group was significantly greater than that in the normal sinus node group (P<0.01), and its effect in the treatment of arrhythmia caused by a damaged sinus node was statistically significant (P<0.05). The main electrophysiological mechanism of racemic higenamine in the treatment of SSS was the enhancement of sinus node self-discipline and improvement of sinoatrial and atrioventricular conduction function.

    Chronic rhinosinusitis (CRS) is a common and potentially debilitating disease characterized by inflammation of the sinus mucosa for longer than 12 weeks. Bacterial colonization of the sinuses and its role in the pathogenesis of this disease is an ongoing area of research. Recent advances in culture-independent molecular techniques for bacterial identification have the potential to provide a more accurate and complete assessment of the sinus microbiome, however there is little concordance in results between studies, possibly due to differences in the sampling location and techniques. This study aimed to determine whether the microbial communities from one sinus could be considered representative of all sinuses, and examine differences between two commonly used methods for sample collection, swabs, and tissue biopsies. High-throughput DNA sequencing of the bacterial 16S rRNA gene was applied to both swab and tissue samples from multiple sinuses of 19 patients undergoing surgery for treatment of CRS. Results from swabs and tissue biopsies showed a high degree of similarity, indicating that swabbing is sufficient to recover the microbial community from the sinuses. Microbial communities from different sinuses within individual patients differed to varying degrees, demonstrating that it is possible for distinct microbiomes to exist simultaneously in different sinuses of the same patient. The sequencing results correlated well with culture-based pathogen identification conducted in parallel, although the culturing missed many species detected by sequencing. This finding has implications for future research into the sinus microbiome, which should take this heterogeneity into account by sampling patients from more than one sinus. PMID:26834708

    The light-microscopic, ultrastructural, and immunohistochemical features of immature sinus histiocytosis were studied in 10 lymph nodes with the histologic picture of toxoplasmic lymphadenitis and compared with the features of lymphoid cells present in the marginal zone of the splenic white pulp. Areas of immature sinus histiocytosis consisted largely of medium-sized lymphoid cells with markedly irregular nuclei and abundant pale cytoplasm. Using a panel of monoclonal antibodies, the predominating lymphoid cells were found to carry the B-cell phenotype B1+Ba1-sIgM+sIgD-OKIa1+. Admixed were variable numbers of larger, blastic lymphoid cells, small lymphocytes, histiocytic elements, and polymorphonuclear granulocytes. The marginal zone of the splenic white pulp was composed of a similar mixture of cells, and marginal-zone lymphocytes demonstrated an analogous immunohistochemical phenotype. Our results indicate that immature sinus histiocytes are B-lymphoid cells that are closely related to marginal zone lymphocytes. As such, immature sinus histiocytes may have a role similar to that of marginal-zone lymphocytes, which have been claimed to transport antigens or immune complexes toward the follicular center or to serve as precursors of plasma cells. We suggest that immature sinus histiocytosis represents an abnormal expansion of the marginal zone, normally present at the sinusoidal pole of lymphoid follicles. The reason for this marginal-zone hyperplasia, recognized as immature sinus histiocytosis in a variety of reactive lymph node conditions, may be a maturation arrest in the normal development of immature sinus histiocytes into small, sIgM+ sIgD+ lymphocytes.

    Transnasal endoscopic surgery has remained at the forefront of surgical management of sinogenic complications involving the frontal sinus, orbit, and anterior skull base. However, the difficulty in accessing certain areas of these anatomical regions can potentially limit its use. Transorbital neuroendoscopic surgery (TONES) was recently introduced to transgress the limits of transnasal endoscopic surgery; the access that it provides could add additional surgical pathways for treating sinogenic complications involving the frontal sinus, orbit, and anterior cranial fossa. We describe a prospective series of 13 patients who underwent TONES for the management of various sinogenic complications, including epidural abscess, orbital abscess, and fronto-orbital mucocele or mucopyocele, as well as subperiosteal abscess presenting with orbital apex syndrome. The primary outcome measurement was the efficacy of TONES in treating these pathologies. TONES provided effective access to the frontal sinus, orbit, and the anterior cranial fossa. All patients demonstrated postoperative resolution of initial clinical symptoms with well-hidden surgical scars. There were no ophthalmologic complications or recurrence of pathology. Based on our experience, TONES appears to provide a valuable addition to the current surgical armamentarium for treating selected complications of sinusitis. PMID:24294556

    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.

    Abstract Odontogenic cutaneous sinus tracts (OCSTs) are generally primarily misdiagnosed and inappropriately treated by virtue of their rarity and the absence of dental symptoms. Accurate diagnosis and treatment and the elimination of the source of infection can reduce the incidence of complications and relieve the pain of the patient. In this case report, we present the case of an 11-year-old patient with an apparent abscess but an unobvious draining sinus tract in his left cheek. Intraorally, a glass-ionomer-cement filling on the occlusal surface of the left mandibular first molar (tooth 36) was noted. Radiographic examination revealed a radiopaque mass inside the crown and pulp chamber and an irregular, radiolucent periapical lesion surrounding the distal root apex. He was diagnosed with an OCTS secondary to a periapical abscess of tooth 36. Precise root canal therapy (RCT) and chronic granuloma debridement was performed; 6 months later, the abscess and sinus had healed completely, and the periapical lesion had resolved. Odontogenic cutaneous sinus tracts are uncommon in the clinic. This case report reminds us of the significance of OCSTs and provides some implications for their diagnosis and treatment.

    Dermoid sinus, a congenital malformation of neural tube development, has been reported in humans and several animal species including dogs. It is typically found in the dorsal midline and commonly occurs in the Rhodesian Ridgeback breed. A case of multiple dermoid sinuses in the fronto-occipital region is described. An 11-month-old, intact female Saint Bernard dog was presented with a 2 day history of discharge from a large irregular subcutaneous mass in the fronto-occipital region. The dog was otherwise healthy. The dog had two circular skin lesions (approximately 4 × 4 and 4 × 2 cm diameter) surrounded by multiple irregular elevated masses. The masses had multiple small openings on the skin surface with tufts of hair protruding from the apertures. The masses were surgically removed, and the diagnosis of multiple dermoid sinuses was confirmed by histological examination. Histopathological examination showed multiple, variably sized, spherical to tubular cysts expanding the dermis and subcutis. Cysts were filled with hair shafts and lamellar keratin and were lined by a stratified squamous epithelium. Sebaceous and apocrine gland adnexal structures were also observed. To the best of our knowledge, this is the first reported case of multiple dermoid sinuses of two different types in the head of a Saint Bernard dog. PMID:24006855

    Objective: To study the structural and functional changes of maxillary sinus mucosae of patients with odontogenic maxillary sinusitis, and to improve the therapeutic effects. Methods: Ten mucosal biopsy samples collected during the surgeries of patients with recurrent odontogenic maxillary sinusitis were selected as Group A. Another ten mucosal biopsy sample were collected during retention cyst-removing surgeries and referred to as Group B. The mucosae were put in 10% neutral formalin solution for 1 day and prepared into 5-7 µm thick paraffin sections which were subjected to hematoxylin-eosin staining. The reactions included: (1) Reaction with T-lymphocyte (CD-3); (2) reaction with T-helper cell (CD-4); (3) reaction with T-suppressing cell (CD-8); (4) reaction with B-lymphocyte (CD-20). Polymeric horseradish peroxidase visualized detection system was used. The contents of CD3, CD4, CD8 and CD20 in the stained cells of the maxillary sinus mucosal layer were calculated. The responses of receptors to muramidase were classified as mild, moderate and strong. All data were analyzed by Statistica 6.0 package for Windows based on Mann-Whitney non-parametric standards. Results: The epithelial tissues in the maxillary sinus mucosa of Group B were covered with multiple rows of cilia. The epithelial cells of Group A suffered from degeneration, shrinkage and desquamation. Different cells were distributed in the autologous mucosal layer, of which macrophages, fibroblasts, lymphocytes and neutrophils were dominant. The average contents of macrophages and lymphocytes accounted for 42.8%. Lymphocyte subset analysis showed that the number of CD3 cells exceeded that of CD20 ones and there were more CD4+ cells than CD8+ ones. T-helper and T-suppressing cells were distributed remarkably differently. CD8+ cells were mainly located inside and under the epithelium, while CD4+ cells were scattered in the autologous matrix. Conclusion: For patients with recurrent odontogenic maxillary

    With the increasing recognition of the pacemaker syndrome and with the availability of newer methods of pacing therapy, the status of the atrioventricular (AV) conduction in patients with Sick Sinus Syndrome (SSS) becomes crucial in the choice of mode of pacing. At the Philippine Heart Center, from April 1983 to November 1986, the sinus and AV node function studies of 46 patients who, by electrophysiological studies had sinus node dysfunction (SND)-SN recovery time (SNRT) greater than 1400 msec, were reviewed. These were arbitrarily classified according to duration of SNRT into: Group A--borderline SND, SNRT from 1,401 to 1,499 msec (n = 4); Group B--mild SND, SNRT from 1,500 to 2,499 msec (n = 25); Group C--moderate SND, SNRT from 2,500 to 3499 msec (n = 6); Group D--severe SND, SNRT of 3,500 m and above (n = 11). Out of the 46, 14 (30%) had concomittant AVN dysfunction (AVND)--antegrade block rate less than 130 beats per minute (BPM). The percentage occurrence of AVND was noted as follows: Group A--25% (1/4); Group B--28% (7/25); Group C--50% (3/6); Group D--27% (3/11). Out of the 14 patients with concomittant AVND, 5(35%) had antegrade block rate less than 100 BPM, 3 in Group B and 2 in Group D. The study shows that AVND occurs in only 30% of SSS patients. Its occurrence and severity has no bearing on the degree of SND. In these, antegrade block was at a rate higher than 100 BPM in the majority of patients.(ABSTRACT TRUNCATED AT 250 WORDS)

    We applied the respiratory sinus arrhythmia (RSA) quantification algorithm to 24-hour ECG recordings of Chagas disease (ChD) patients with (G1, n=148) and without left ventricular dysfunction (LVD) (G2, n=33), and in control subjects (G0, n=28). Both ChD groups displayed a reduced RSA index; G1=299 (144-812); G2=335 (162-667), p=0.011, which was correlated with vagal indexes of heart rate variability analysis. RSA index is a marker of vagal modulation in ChD patients.

    Background Inappropriate sinus tachycardia (IST) and postural tachycardia syndrome (POTS) are 2 disorders characterized by sinus tachycardia. It is debated whether the pathophysiology of IST and POTS results from abnormal autonomic regulation or abnormal sinus node function. We hypothesized that intrinsic heart rate (IHR) after autonomic blockade would be increased in patients with IST but not POTS. Methods and Results We enrolled 48 POTS patients, 8 IST patients, and 17 healthy control (HC) subjects. Intravenous propranolol and atropine were given to block the sympathetic and parasympathetic limbs of the autonomic nervous system in order to determine the IHR. Patients with IST have a higher sympathetic contribution to heart rate when compared with POTS patients (31±13 bpm versus 12±7 bpm, P<0.001) and HC (8±4 bpm; P<0.001) and a trend to less parasympathetic contribution than POTS and HC (IST: 31±11 bpm versus POTS: 46±11 bpm versus HC: 48±11 bpm, ANOVA P=0.108). IHR was not significantly different between IST and either POTS or HC (IST: 111±11 bpm versus POTS: 108±11 bpm versus HC: 106±12 bpm, ANOVA P=0.237). Conclusions IST patients have more sympathetic tone when compared with either POTS or HC, but IST patients do not have abnormal sinus node automaticity. These data suggest that the treatment of IST and POTS should focus on sympatholysis, reserving sinus node modification for patients with continued debilitating symptoms after beta‐blockade and possibly ivabradine.

    Various pathologic conditions can occur in the renal sinus, primarily originating in the constituents of the renal sinus, and the renal sinus can be secondarily involved by surrounding renal parenchymal and adjacent retroperitoneal lesions. Lipomatosis and cysts are common renal sinus lesions with little clinical significance, but differentiation from other pathologic conditions is important. Renal vascular lesions such as renal artery aneurysm or arteriovenous fistula can mimic other parapelvic or peripelvic lesions at excretory urography, but their vascular nature is evident at color Doppler ultrasonography, contrast material-enhanced computed tomography (CT), and magnetic resonance (MR) imaging. Although most tumors originating in the renal pelvis are transitional cell carcinoma or squamous cell carcinoma, renal parenchymal tumors such as renal cell carcinoma or benign multilocular cystic nephroma have a tendency to grow into the renal sinus. Rare tumors of mesenchymal origin can develop in the renal sinus, but their imaging findings are nonspecific. The observation of renal sinus fat is important for detecting a small tumor located in that area and determining the exact tumor stage. Multiplanar CT or MR images can allow exact evaluation of the extent of complex renal sinus disease.

    There are asymmetries in the sizes of transverse sinus and intraocular pressure. The purpose of this study was to investigate possible relationships between the asymmetry of transverse sinuses in TOF MR venography and intraocular pressures of right and left eyes. In this study, subjects were 63 male and 42 female medical school students, aged 18-21 years (mean+/-SD; 19.72+/-0.67 years). Subjects with neurological and ophthalmologic disease, particularly dural sinus thrombosis, myopia, trauma and glaucoma, were excluded the study. Subjects were divided into five groups according to the magnitudes of the right- and left-transverse sinuses in MR venography results. There is a functional relation between intraocular pressures of the right and left eyes and asymmetry of the transverse sinus. If the transverse sinus on one side is larger and its venous drainage is greater, the intraocular pressure of the eye on this side is lower. It can be speculated that the transverse sinus size may be associated with pathogenesis of diseases with increased intraocular pressure such as glaucoma. We aim to determine the relation between the size and drainage of transverse sinuses in TOF MR venography and intraocular pressure in patients with open-angle glaucoma in our next study.

    The use of the microdebrider provides an excellent, safe and thorough technique in functional endoscopic sinus surgery. It provides atraumatic dissection with minimal bleeding which enables decreased surgical time and faster postoperative healing. It is easily learned and requires minimal supplemental instrumentation. We feel that it is a superior technique in the practice of functional endoscopic sinus surgery.

    The present longitudinal study examined relations between respiratory sinus arrhythmia (RSA) development and social responsiveness characteristics associated with autism spectrum disorders. Group-based developmental trajectory modeling was used to characterize RSA development patterns in 106 typically developing children across 5, 10, 24, 36, and 48 months of age. A two-group model fit of RSA development was found: a "typically" and "atypically" developing group. The typical group gradually increased in RSA across 5-48 months of age. The atypical group, however, increased in RSA from 5 to 24 months and demonstrated a plateau or "delay" in RSA development from 24 to 48 months. The atypical RSA development group also demonstrated more difficulties in parent-reported social responsiveness at 48 months. The results support current literature that identifies RSA as a marker of social functioning level. PMID:23341170

    We have presented a case of ruptured aneurysm of sinus of valsalva, in a female of 24 years old, with the symptoms and signs of right heart failure. Diagnosis made by echocardiography. For further evaluation, cardiac catheterization was done. After improvement of her general condition, she was undergone operation. Per-operative findings were bicuspid aortic valve having no calcification. A fistulous tract having windsock appearance found in between fused RCC & NCC extending into the RV cavity, which was opened inferior to the tricuspid valve. Fistulous tract was excised and the opening in the root of the aorta was closed with PTFE patch by 5/0 polypropylene and RV side was closed by direct suture. Patient was symptomless after operation. Patient discharged on eighth postoperative day in stable condition. PMID:27612913

    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.

    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.

    Introduction Sinus infections, sore throats, and upper respiratory tract infections (URI) are common reasons patients seek medical care. Well-established treatment guidelines exist for prescribing antibiotics in these clinical scenarios, but are not often followed. Objective The objective of this study is to determine practice patterns related to prescribing antibiotics for sinusitis, URI, and pharyngitis. The main hypothesis is that attending physicians improve their adherence to antibiotic guidelines with a learner present. Methods A retrospective cohort study was performed on patients treated for URI, sinusitis, and pharyngitis at an ambulatory faculty practice. The use of relevant ICD-9 codes from January 1, 2008 to January 30, 2012 resulted in 1,548 patient encounters which were reviewed for guideline adherence. Univariate analysis and multivariate logistic regression was performed for each outcome variable to determine if they influence antibiotic adherence. Variables studied were physician, presence of a learner, BMI, age, gender, day of the week, month, diabetes, immunosuppression, and COPD. Results Multivariate analysis showed the statistically significant variables were age (p=0.038) for pharyngitis and provider (p=0.013) for URI. There were no significant findings for sinusitis. Guideline adherence was 24% in patients with pharyngitis, 42% in acute sinusitis, 79% in URI, and 57% overall. Conclusion Guideline adherence varies depending on the treating physician and decreases when treating younger patients with pharyngitis. The presence of a learner did not improve prescribing habits. The reason for these findings remain unclear, but considerations for improvement could include following antibiotic adherence as a quality measure, giving patients handouts educating them about the impact of overprescribing antibiotics, and further education amongst faculty and residents about adhering to nationally recognized guidelines.
