    2013-01-01

    Cerebrospinal fluid (CSF) rhinorrhoea results from a direct communication between the CSF-containing subarachnoid space and the mucosa-lined space of the nasal cavity and paranasal sinuses. We present a case of 40-year-old woman, presenting with clear, watery discharge through the right nostril spontaneously. The CT cisternography confirmed the diagnosis of sphenoid sinus CSF rhinorrhoea, with no intracranial pathology. The patient was managed by transnasal endoscopic procedure, wherein bath plug technique was followed using temporalis fascia and overlay grafting with fascia lata and fibrin glue. The patient has been symptom free for the last year. PMID:23616328

    2013-01-01

    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. PMID:23964041

    2015-01-01

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

    Presenting symptoms of the isolated sphenoid sinus lesion are often vague and non-specific. Diagnostic nasal endoscopy procedures and imaging techniques are of great value for an early and precise diagnosis. Moreover, endoscopic sinus surgery is a safe and effective technique that allows a direct route to the sphenoid sinus. Because of its close vicinity to important and vulnerable structures of the skull base, delay in diagnosis and treatment can be potentially lethal. Endoscopically controlled procedures for the sphenoid sinus provide the surgeon with an obvious alternative to the traditional approaches. From November 1994 to May 2001 the authors operated on 41 patients with isolated sphenoid lesions. The pathology spectrum was rather wide and included 11 cases of isolated fungal sinusitis, 10 mucoceles, 7 bacterial sinusitis, 7 cerebrospinal fluid leaks, 3 inverted papillomas, 1 chondrosarcoma, 1 ossifying fibroma and 1 foreign body. The sphenoid sinus was the only sinus involved, and lesions arising from adjacent tissues were excluded. In this paper, the authors present clinical symptoms, endoscopic findings and imaging data as well as endoscopic surgical techniques for the treatment of sphenoid sinus disease. PMID:15060830

    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. PMID:22133966

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

    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.

    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.

    2013-01-01

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

    Cholesterol granuloma (CG) is usually associated with chronic middle ear disease, and is not common in the paranasal sinuses. Additionally, it is very rare for cases of CG to be associated with a fungal infection. However, in this paper, we report a case of sphenoid sinus CG that is associated with aspergilloma in a 78-year-old male patient who presented with right hemifacial pain, headache and toothache. CT revealed the presence of an expansile cystic mass lesion in the sphenoid sinus that showed a high signal intensity on both the T1 and T2 weighted images. This mass was later determined to be CG. The suspected etiologic mechanisms of both CG and aspergilloma of the paranasal sinuses are similar, and impaired drainage and obstruction of the ventilation of the paranasal sinuses are considered to be the causative mechanism of both diseases. Overall, the results of this study indicate that the use of MRI findings could be helpful for differentiating CG from other paranasal sinus mass lesions. PMID:18607122

    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. PMID:26221856

    The purpose of this study is to determine the anatomical features of the sphenoid sinus using computerized tomography (CT). 100 Sudanese subjects were investigated for CT sinuses; Characterization of the sphenoid sinus and seven horizontal and vertical measurements were evaluated. Onodi cell was found in 13 subjects, 10 of them were sellar and 3 were pre-sellar. Pneumatization was of the sellar type in 85%, presellar was 15%, and no subject was chonchal. The mean length of vertical lines from the center of sphenoid ostium to the roof and bottom were 10.6 ± 3.1 mm, 11.1 ± 3.7 mm respectively. When the sphenoid ostium was located superior to the lowest point of the sella, the line from the center of the sphenoid sinus ostium to the posterior wall of the sinus was 15.2 ± 4.2 mm and when was located inferior, the line was 26.3 ± 5.2 mm on average. The mean length from the lowest point of the sella to the anterior wall of sphenoid sinus was 16.8 ± 3.6 mm. The line from anterior wall to posterior wall of sphenoid sinus lining skull base was 10.9 ± 3.2mm mm. The maximum depth was 25.2 ± 6.9 mm and the maximum width was 18.4 ± 5.9mm. The differences in the sphenoid sinus character take place between males and females. The study provides essential anatomical information for Sudanese subjects and its impact in the clinical surgical practice. PMID:24373273

    Paranasal sinus injuries by foreign bodies have a lower incidence compared with facial injuries. Among them, penetrating maxillofacial injuries to the sphenoid sinus and skull base remain rare. We report the case of a 41-year-old man who presented with, after a missile-related maxillofacial injury, a metallic foreign body enclosed within the sphenoid sinus with carotid-canal fracture. Angiographic evaluation showed a mass in the right internal carotid artery. The foreign object was successfully extracted through a transmaxillary sublabial approach with a good outcome. We discuss the extensive preoperative evaluation and interdisciplinary management of this unusual injury. PMID:17628677

    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

    We report the case history of a patient with a sphenoid sinus mucocoele detected by computed tomography and medical resonance imaging. The patient had a history of nasopharyngeal carcinoma, which was treated by radiotherapy more than 10 years previously. He presented with bilateral twelfth and sixth cranial nerve palsies. Local tumour recurrence was suspected. Further investigations showed that the cranial nerve palsies were caused by radiation damage and the sphenoid sinus mucocoele was an incidental finding. Sphenoid sinus mucocoele is a possible rare late complication of radiotherapy in patients with nasopharyngeal carcinoma. PMID:11716228

    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

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

    2015-01-01

    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

    2016-01-01

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

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

    Burkitt lymphoma is a high-grade B-cell non-Hodgkin lymphoma. The endemic form of this malignancy occurs primarily in children aged 5 to 7 years, and it presents with jaw and facial bone involvement. The sporadic form affects older children (mean age: 12.2 yr) and often manifests as an abdominal mass; it rarely involves the head and neck. The presence of any type of lymphoma in the paranasal sinuses is rare. We report a case of Burkitt lymphoma that originated in the sphenoid sinus in a 66-year-old white woman. The patient presented with hypoesthesia in the left V1 and V2 distributions and frequent left-sided headaches. Imaging revealed that the destructive lesion had spread into the cavernous sinus and infratemporal fossa. Repeat imaging showed progression of the lesion in just 1 month. An endoscopic sphenoidotomy was performed to obtain a tissue specimen, and a diagnosis of sporadic Burkitt lymphoma was established on the basis of its clinical, morphologic, and immunohistochemical characteristics. The patient underwent chemotherapy and radiation. Short-term follow-up imaging showed that the lesion had disappeared, and the patient remained disease-free at 3 years of follow-up. This case is one of the few reported cases of true adult Burkitt lymphoma originating in the sphenoid sinus. We discuss the rapid progression of the disease and the considerable amount of invasion that can occur with minimal symptoms. PMID:19623516

    We present a 70-year-old man with lymphoma who presented with a right eye movement disorder. CT examinations showed ‘ground-glass’ appearance extending around the right sphenoid sinus which suggested fibrous dysplasia. However, biopsy from the mass histologically proved it to be diffusing large B-cell lymphoma and positron emission tomography examinations revealed increased fluorodeoxyglucose (FDG) uptake around the right sphenoid bone and multiple spinal bones. After chemotherapy for lymphoma, abnormal FDG uptake disappeared from the body. PMID:25100815

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

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

    Background Mucormycosis is a fungal infection with the following 5 classic forms: cutaneous, pulmonary, gastrointestinal, disseminated, and rhinocerebral. The rhinocerebral form can be rapidly progressive and invasive with a high mortality rate. We present a case of a 38-year-old man with invasive mucormycosis that led to a basilar artery territory stroke. Rhinocerebral mucormycosis is an unusual cause of stroke. Case Report A 38-year-old man with a past medical history of diabetes mellitus presented with altered mental status. A lumbar puncture revealed eosinophilic pleocytosis with a mildly elevated total protein and borderline low glucose level. CT revealed a left medullary and cerebellar infarct confirmed by MRI. MRI also displayed a diffuse marrow signal abnormality in the clivus with contiguous sinus disease. Endoscopic sinus surgery confirmed that the fungal sinusitis was mucormycosis of the Rhizopus genus, which had affected the left sphenoid sinus, invaded through the skull base, and involved the basilar artery. He was given liposomal amphotericin (500 mg i.v.) with posaconazole (400 mg i.v. twice daily). Due to the severity of the invasion and poor prognosis, the patient was discharged with comfort care measures. Discussion Clinicians should be aware of invasive sinusitis as a rare cause of stroke in diabetics. Once the subarachnoid space and basal arteries of the brain have been invaded, the prognosis is very poor. The key to improvement of outcomes is early recognition and treatment, and examination of the sinuses on neuroimaging in all cases of stroke is vital. PMID:25873889

    In immunocompromised patients, invasive molds such as Aspergillus and Mucor can lead to locally aggressive angioinvasive infections that are often life-threatening. A particularly devastating complication is the development of a fungal mycotic aneurysm resulting from invasion of the arterial wall. Due to anatomic contiguity, the sphenoid sinus provides potential access for these fungi, which often colonize the respiratory sinuses, into the cavernous sinus and internal carotid artery (ICA), thus leading to the formation of ICA aneurysms. The ideal treatment of fungal ICA aneurysms includes a combination of surgical debridement and long-term effective antifungal therapy, but the role of endoscopic resection and the duration of antimicrobials are poorly defined. Here, we present the case of a 71-year-old immunocompromised patient who developed an ICA mycotic aneurysm, associated with a proven invasive fungal infection (presumptively Mucorales) of the sphenoid sinuses, as defined by EORTC/MSG criteria, and who survived after undergoing coil embolization with parent vessel sacrifice of the aneurysm in combination with liposomal amphotericin B. We also review the literature for published cases of invasive fungal sphenoid sinusitis associated with mycotic aneurysms of the ICA and provide a comparative analysis . PMID:26687073

    Chondromyxoid fibroma (CMF) is a rare benign primary tumor which usually affects the metaphyses of the long bone of the lower extremities in childhood and young adults. Rarely, CMF occurs in the skull base and parasinuses, which may be difficult to distinguish from chondrosarcoma or chordoma and other tumors in the head. It is composed of chondroid, myxoid, and fibrous tissue growth in a lobular pattern, infrequently with calcifications. We report one case of CMF involving the sphenoid sinus mimicking a chondrosarcoma. The tumor mass showed calcifications on images and histology. PMID:19644549

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

    Ewing's sarcoma (ES) is an aggressive tumour that may present with skeletal and extraskeletal forms. The extraskeletal form is rarely encountered in the head and neck region and is extremely rare in the sinonasal tract. This is the case report of a ES of the ethmoid sinus with intracranial and orbital extension in a 33-year-old male patient who presented with anosmia, epistaxis, reduction of visual acuity in the left eye and headache. On otorhinolaryngological clinical examination and biopsy via flexible endoscope, the lesion was misdiagnosed as ethmoid sinus carcinoma. The subsequent magnetic resonance imaging (MRI) of the brain revealed a large mass (6×7 cm) eroding the ethmoid and sphenoid sinuses, extending beyond the orbits and occupying the anterior cranial fossa with a maximum extension of ~5 cm. The patient underwent surgical resection and the microscopic examination of the specimen established the diagnosis of ES (immunohistochemically positive for CD99, neuron-specific enolase, CD56, synaptophysin, pancytokeratin, low-molecular weight cytokeratins and vimentin. The periodic acid Schiff stain exhibited strong intracytoplasmic block positivity and fluorescence in situ hybridization revealed a t(22;11) translocation. First-line chemotherapy was administered for 3 cycles; however, on restaging MRI, local disease progression was diagnosed. The patient received radiotherapy and second-line chemotherapy for 6 cycles. At 15 months after the diagnosis, the patient remains recurrence-free and maintains a good functional status and quality of life. PMID:26171185

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

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

    Isolated sphenoid sinus disease (ISSD) describes a wide spectrum of pathologies including inflammatory, vascular, bony dysplastic, and neoplastic diseases. The aim of this study was to assess the frequency with which a neoplastic process was diagnosed in patients of ISSD and patient management strategies. A retrospective analysis was conducted for all ISSD patients who underwent surgery between January 2005 and January 2014 at a tertiary center. The clinical characteristics, radiologic studies, operative findings, endoscopic surgical techniques, pathology results, and treatment outcomes of the patients were analyzed. In all, 42 patients (31 women and 11 men) were included in the study. Histopathologic examinations revealed that 10 patients (23.4%) had neoplasms (8 benign and 2 malignant), 19 (45.2%) had mucocele, 7 (16.7%) had fungal disease, and 6 (14.3%) had meningoencephalocele and cerebrospinal fluid leakage. With the exception of 2 patients with plasmacytoma, complete removal of the lesions was achieved in all patients using transnasal or transethmoidal endoscopic approaches, and no local recurrences were observed during the mean follow-up period of 42 months. More than one fifth of the patients with ISSD were diagnosed with neoplasms. The results indicated that endonasal endoscopic approaches could effectively help manage patients with ISSD lesions, including those that were neoplastic. It is clear that precaution during preoperative planning is imperative to avoid unexpected situations and complications that may put surgeons in a difficult position during surgery. PMID:26703030

    Cerebrospinal fluid (CSF) leakage is a common but sometimes serious complication after transsphenoidal surgery (TSS). To avoid this postsurgical complication, we usually repair the CSF leaking area using an autologous material, such as fat, fascia, or muscle graft and sometimes nasonasal septal flap. In this report, we propose a technique using a novel autologous material, sphenoid sinus mucosa (SSM), to repair intraoperative CSF leakage or prevent it postoperatively. On 26 February 2007, we introduced the technique of using SSM to repair or prevent CSF leakage in TSS. Until 30th of June 2014, we performed 500 TSSs for patients with pituitary or parasellar lesions. They were 195 men and 305 women with a mean age of 48.5 years (range, 5-85 years). We used SSM for patching or suturing the arachnoid laceration or dural defect, in lieu of fat or fascia harvested from abdomen or thigh, or made pedicle flap of SSM instead of nasonasal septal flap to cover the sellar floor. Comparing the previous 539 cases not using these techniques before 26 February 2007, intraoperative CSF leakage increased from 49 to 69.4% (p < 0.0001) due to more aggressive surgical technique, mainly related to more extensive approaches and lesion removals, but the rate of using fat was reduced significantly from 35.5 to 19.4% (p = 0.00021) in small or moderate CSF leaks during TSS without increasing the reoperation rate for postoperative CSF leaks (1.86 vs 1.2%, p = 0.45). The technique of using SSM to repair intraoperative CSF leaks or prevent them postoperatively in TSS was considered useful, effective, less invasive, easier for graft harvesting (same surgical field), and providing natural anatomical reconstruction, without potential donor site morbidity. We can recommend it as a standard method for CSF leaks repair and prevention in TSS. PMID:26338198

    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

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

    Objectives The purpose of this study was to cephalometrically evaluate the pharyngeal airway space and frontal and sphenoid sinus changes after maxillomandibular advancement counterclockwise rotation for class II anterior open bite malocclusion. Methods The study included 49 patients (98 lateral teleradiographs; 36 females and 13 males) who were analysed in the pre-operative (1 week before surgery) and post-operative (6 months after surgery) periods. In each lateral teleradiography, the dimensions of the inferior and superior pharyngeal airway space, TB-PhW1 [the point between the posterior aspect of the tongue to the dorsal pharyngeal wall (oropharynx) (TB) and the point on the dorsal pharyngeal wall closest to TB (PhW1)] and UP-PhW2 [and the point between the posterior aspect of the soft palate to the dorsal pharyngeal wall (nasopharynx) (UP) (PhW2)] measurements were evaluated, as well as the dimensions of the frontal and sphenoid sinuses. The differences between the two operative times were evaluated by Student's t-test. Results All measurements showed excellent reproducibility for the intraclass correlation coefficient (ICC > 0.9; p < 0.0001). There was an increase in the measurements TB-PhW1 and UP-PhW2 and a decrease in the dimensions of the frontal and sphenoid sinuses after orthognathic surgery. Conclusions The morphology of the superior and inferior pharyngeal airway space and frontal and sphenoid sinuses changes after 6 months of maxillomandibular advancement counterclockwise rotation for class II anterior open bite malocclusion.

    Orbitofacial dermoid cysts in children are treated using surgical excision. Dermoid cysts of the frontotemporal region usually present as superficial, slow-growing masses without deep extension. We report a rare case wherein a frontotemporal dermoid in a 21-month-old girl presented with a draining sinus tract to the skin and extended intracranially through the sphenoid bone. It was removed surgically and a dermoid cyst was removed from the frontotemporal region, extending superficially from the skin sinus tract through the sphenoid bone and attaching to the dura of the anterior temporal lobe. In addition to our case presentation, a literature review was performed to identify the few reported similar cases in the published literature, the combination of which suggests that frontotemporal dermoid cysts with associated draining sinus tracts may require preoperative imaging with computed tomography or magnetic resonance imaging before surgical intervention because of the high likelihood of intracranial extension.

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

  15. Frontal Sinus Mucopyocele Presenting as a Subcutaneous Forehead Mass.

    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.

    Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy, SHML) is a rare, non-hereditary, benign histiocytic proliferative disorder, presenting as painless bilateral cervical lymphadenopathy, with systemic symptoms. Extra nodal manifestations have been reported in 28-43 % cases with rare ocular involvement. We report a case of a 57 year old female presenting with gradual progressive decrease of vision OU since 8 months associated with epistaxis. 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.

    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

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

    PubMed

    Peyrol, Michael; Lévy, Samuel

    2016-06-01

    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

    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.

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

    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

    Gas within the cavernous sinus is an unusual finding. We report three patients who demonstrated gas in the cavernous sinus on computerized tomography (CT). The clinical information of these patients was reviewed for the possible source of the gas and the symptoms induced by the gas. Cavernous sinus gas was seen in two patients with sphenoid sinus fracture and in one patient after intravenous fluid infusion. None of the patients had symptoms referable to the cavernous sinus gas, but one patient had a grave prognosis due to trauma. Identification of cavernous sinus gas on CT and correlation with the clinical information is mandatory for further management. PMID:10934814

    2016-10-01

    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

    2015-04-01

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

    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.

    Andrews, Jamie N; Weitzel, Erik K; Eller, Robert; McMains, Christopher K

    2010-05-01

    The standard of care treatment for diffuse recurrent sinus barotrauma (RSB) is an endoscopic sphenoethmoidectomy with a complete frontal dissection. Successful healing leaves the RSB patient with no ethmoid sinuses and endoscopically patent frontal, sphenoid, and maxillary ostia. In persistent cases, patients with small frontal ostia will go on to require a frontal drillout. Patients presenting for surgical management of RSB generally have minimal sinus disease despite significant symptoms during flight and the prospect of extensive surgical management can be unappealing. With the advent of balloon sinuplasty, military otolaryngologists anticipated this technology would permit therapeutic dilation of sinus ostia without the extensive surgical dissection and prolonged recovery typical for standard of care management. This case report is a cautionary note to the wider flight community to recognize a mechanism for recurrence of the underlying pathology when balloon sinuplasty is used that is not possible after properly performed standard of care sinus surgery for RSB.

    2015-01-01

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

    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. PMID:12602451

    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

    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

    2011-01-01

    Cavernous sinus syndrome is rarely caused by tertiary syphilitic infection. To our knowledge only two other cases of cavernous sinus syndrome caused by syphilis have been reported in the literature. We report a case of a 62-year-old female who presented with a mass in the cavernous sinus, which was initially diagnosed as a meningioma radiologically, necessitating a biopsy for diagnostic confirmation. Clinical features of syphilitic aortitis and subsequent positive neurosyphilis laboratory results lead to the suspicion of a gumma infiltrating the cavernous sinus. Empirical treatment with penicillin in an attempt to defer the need for biopsy led to both significant clinical improvement and radiological resolution. This confirmed the diagnosis of a syphilitic gumma in the cavernous sinus. In this paper we emphasize the rarity of cavernous sinus syndrome as a result of syphilitic infection, highlight the diagnostic difficulties using current serological and radiological measures, and propose treating intracerebral mass lesions in serum positive cases empirically prior to more invasive measures.

    2016-01-01

    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

    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. PMID:25228678

    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. PMID:26694306

    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

    2014-01-01

    A fungus ball is an extramucosal fungal proliferation that completely fills one or more paranasal sinuses and usually occurs as a unilateral infection. It is mainly caused by Aspergillus spp in an immunocompetent host, but some cases of paranasal fungal balls reportedly have been caused by Mucor spp. A Mucor fungus ball is usually found in the maxillary sinus and/or the sphenoid sinus and may be black in color. Patients with mucormycosis, or a Mucor fungal ball infection, usually present with facial pain or headache. On computed tomography, there are no pathognomonic findings that are conclusive for a diagnosis of mucormycosis. In this article we report a case of mucormycosis in a 56-year-old woman and provide a comprehensive review of the literature on the "Mucor fungus ball." To the best of our knowledge, 5 case reports (8 patients) have been published in which the fungus ball was thought to be caused by Mucor spp. PMID:25397383

  9. Cholesterol Granule of the Ethmoid Sinus: A Case Report.

    2016-02-01

    Cholesterol granuloma (CG) is common in the mastoid air cells, less common in the skull base and orbit, and uncommon in the paranasal sinuses. The most commonly affected sinus is the maxillary sinus, and it is very rare in the ethmoid and sphenoid sinus. CG is thought to be due to impair the venous and lymphatic drainage from the sinus cavity. In the early period of the disease, the patient has no symptoms but when the expanding cysts compress the surrounding structures, they cause bony erosion that leads to clinical symptoms such as nasal blockage, eye pain or visual loss. If the patients' presentation does not correlate with physical examination, concerns are raised, and imaging should be performed. This study reports a case of cholesterol granuloma of the ethmoid sinus treated with the endoscopic marsupialization technique. This paper will remind physicians of the characteristics of cholesterol granuloma, which are useful for differential diagnosis of patients with this condition. In addition, it is the first reported case of cholesterol granuloma of the ethmoid sinus in the Thai literature. PMID:27266241

    2009-01-01

    Introduction Chronic pyelonephritis is associated with progressive renal scarring and occurs, most of the time, in patients with major anatomical anomalies, including urinary tract obstruction, calculi, renal dysplasia or vesicoureteric reflux. We report the computed tomography imaging findings of a patient with chronic pyelonephritis appearing as a renal sinus mass. To our knowledge, it is the first time that such a case has been published in the literature. Case presentation We present a case of a 68-year-old woman who underwent a computed tomography scan of the abdomen in the work-up for recently diagnosed hypertension. A non-enhancing left renal sinus mass was detected extending to the para-aortic space. The initial diagnosis was that of a tumor of the collecting system. Nephro-ureterectomy was performed and the pathology results revealed changes of chronic pyelonephritis. Conclusion Chronic pyelonephritis presenting as a renal sinus mass is reported for the first time in the literature. This may lead to the conclusion that diagnostic ureteropyeloscopy and biopsy should be performed prior to radical surgery for possible upper tract urothelial tumors. PMID:19918288

    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.

    A 42-year-old man presented with frequent minor nasal bleeds since 1 month. He was undergoing chemotherapy for pulmonary tuberculosis. MRI brain revealed a space occupying lesion in the right cavernous sinus extending to sphenoid sinus, with T2 inversion. An initial diagnosis of fungal granuloma was made and endoscopic trans-nasal biopsy was attempted. During surgery, a pink pulsating mass was seen in the sphenoid sinus and the procedure was abandoned. A cerebral CT-angiography done subsequently revealed a giant right cavernous segment internal carotid artery (ICA) aneurysm. He was then referred to our centre and upon admission he collapsed secondary to a major bout of epistaxis. An emergency cervical carotid artery ligation resulted in transient control of epistaxis. Owing to recurrence of bleed, trapping of the aneurysm was done resulting in cure. The present case shows that a giant cavernous ICA aneurysm can occasionally be erroneously diagnosed as fungal granuloma. PMID:23010464

    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. PMID:25351797

    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 We report here on a rare case of a large, lateral sphenoid wing tumor with radiographic and intraoperative findings highly suggestive of meningioma, yet pathology was in fact consistent with metastatic prostate adenocarcinoma. Presentation of case An 81 year-old male presented with expressive dysphasia, right-sided weakness and headaches. Imaging revealed a heterogeneously-enhancing lesion based on the left lateral sphenoid wing. The presumed diagnosis was strongly in favor of meningioma, and the patient underwent complete resection of the dural-based lesion. Final pathology confirmed the unexpected finding of a metastatic prostate adenocarcinoma. Although he tolerated surgery well, the patient was subsequently referred for palliative therapy given findings of widespread systemic disease. Discussion Intracranial metastases may involve the dura, at times presenting with rare radiographic features highly suggestive for meningioma, as in our case here. This makes differentiation, at least based on imaging, a challenge. Elderly patients presenting with neurological deficits secondary to a newly-diagnosed, dural-based lesion should thus be considered for metastasis, prompting additional imaging studies (including body CT, MRI or PET) to rule out a primary lesion elsewhere. In some cases, this may affect the overall decision to proceed with surgical resection, or alternatively, to proceed directly to palliative therapy (the latter decision made in the context of widespread metastatic disease). Conclusion We conclude that dural-based metastatic lesions may mimic meningiomas, warranting thorough pre-operative work-up to exclude the possibility of metastasis. In certain cases, identification of widespread disease might preclude surgery and favor palliation, instead. PMID:26318129

    Anomalous origin of the right coronary artery from the left sinus of Valsalva and coursing between the aorta and pulmonary artery is a rare congenital abnormality representing less than 3% of the congenital coronary anomalies. Patients can present with myocardial ischemia, arrhythmias, or sudden cardiac death (SCD). This diagnosis should be suspected in young patients without risk factors for coronary artery disease and the diagnosis can be confirmed easily by 64-slice MDCT angiography. Surgery is generally recommended in symptomatic patients whereas conservative management in asymptomatic patients. Incidence of SCD is rare after the age of 35 years and hence conservative treatment may be advised in asymptomatic patients over the age of 35 years. PMID:27133342

    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.

    The prevalence of Aspergillus sinusitis is often underestimated because the vast majority of cases are classified as "unspecified sinusitis". Two possible aetio-pathogenic mechanisms can be involved in the development of this fungal infection. Traditionally, the literature emphasised the "anglophone" hypothesis which is based on the inhalation of spores. More recently, the "french" model, based on oro-sinusal fistula and/or the perforation of the maxillary sinus by root canal-filling material, is believed to explain the majority of cases in our industrialised environments. Still, neither model explains the totality of cases and several remain beyond comprehension. The disease most commonly presents as a chronic bacterial sinusitis. The process can however become invasive, thus resembling malignancy, with eventually a fatal outcome. Doctors and dentists should know the possible danger, presented by zinc-oxide-eugenol-paste in the sinus. Radical surgery is the treatment of choice, since a prolonged conservative approach (antibiotics, corticosteroids) can only worsen the prognosis. This paper discusses different aspects of the disease, and presents 10 cases, observed at the University Hospitals of Paris (France) and Leuven (Belgium). PMID:2406288

    Cavernous sinus (CS) dural arteriovenous fistula (dAVF) patients presenting with only headache as an initial symptom are not common. Patients with CS-dAVF commonly present with symptoms related to their eyes. In all three patients, headache was the initial symptom. Other symptoms related to the eyes developed 1 - 7 months after headache. In one patient, headache was controlled by sumatriptan succinate, but not diclofenac sodium or loxoprofen sodium. In another patient, headache was controlled by loxoprofen sodium. In the third patient, headache was improved by stellate ganglion block. In all patients, magnetic resonance angiography (MRA) in the early stage of the clinical course showed abnormal blood flow in the CS. However, reflux to the superior ophthalmic vein (SOV) was not detected. As treatment, transarterial and transvenous embolizations were necessary for one patient, and transvenous embolization was performed for another patient with significant blood flow to the SOV and cortical veins. On the other hand, manual compression of the bilateral carotid arteries at the neck resulted in disappearance of the fistula in the third patient. In all patients, the symptoms improved after the disappearance of blood reflux to the CS. The refluxed blood to the CS might cause elevation of the CS pressure and stimulate the trigeminal nerve in the dural membrane, resulting in headache before developing reflux in an anterior direction. CS-dAVF could induce both migraine and common headache. In cases with blood reflux to the CS on magnetic resonance imaging and/or MRA even without eye symptoms, a differential diagnosis of CS-dAVF should be taken into consideration. PMID:26985257

    We present a case of 77-year-old immunocompetent patient who initially presented with vertigo, nausea and vomiting, with symptoms later progressing to headaches and increased lethargy. Brain MRI revealed ring-enhancing lesions typical of abscesses in the right cerebellum. Transoesophageal echocardiogram (TEE) was performed to look for the source of his abscesses, and uncovered a sinus venosus type atrial septal defect. Cardiac CT was carried out; the patient was found to have a sinus venosus atrial septal defect with partial anomalous pulmonary venous return. Moreover, dental examination showed multiple dental caries with poor oral hygiene. The patient was started on intravenous empiric antibiotics and steroids. Subsequent brain imaging showed almost complete resolution of the abscesses. The patient's symptoms started to improve, and he was eventually sent to an intensive rehabilitation centre with future plans to surgically correct his congenital heart disease to prevent further complications.

    A 45-year-old man was admitted to our hospital because of progressive inactivity and mild disturbance of consciousness which appeared two weeks ago. Brain CT revealed symmetric hypointensity of bilateral thalamus, and the lesion appeared hyperintensity on T2 weighted MRI image. He was first considered as immune-mediated cerebritis, and steroid pulse therapy was applied, but the clinical features were not improved. The diagnosis of cerebral venous thrombosis was established, when MR venography (MRV) showed severe stenosis in straight sinus. Consciousness was improved after the start of anticoagulation therapy, but mild dementia was remained as a sequela. MRV was useful to distinguish straight sinus thrombosis from cerebritis in this case. PMID:17260809

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

    Sinonasal polyps are benign lesions arising from nose and/or sinuses mucosa. Paranasal sinuses computed tomogram (CT) scan are important for functional endoscopic sinus surgery (FESS) as their information assist the surgeon in pre-operative planning. This study aimed to show importance of CT scan in evaluation of anatomical variations to prove a correlation with disease process and extent of disease in sinonasal polyposis patients. A study was done from Sept, 2010 to Sept, 2011 with 33 patients presenting with nasal polyps. All recruited patients, after thorough history, general examination and thorough ENT examination, were examined by nasal endoscopy and sinus CT scans. All scans were carried out using a 3 mm thickness in axial and coronal planes with sagittal reconstruction. An analysis was then carried out to see anatomical variations and disease extent in CT scans. Maxillary sinus was the most commonly and most severely affected sinus, while the sphenoid sinus was the least involved sinus. Ostiomeatal complex (OMC) was found to be blocked in 84.85 % cases. There were few anatomic variations (57.58 %) found as hypertrophied uncinate process (30.30 %), septal deviation (21.21 %), skull base type-2, Concha bullosa, Haller's cell, Paradoxical middle turbinate, Onodi cell, pneumatized crista galli and dehiscent skull base. Hyperdense and heterogeneous opacification in paranasal sinuses was seen in 12.12 % patients. Importance of CT scans is to know anatomical variations as etiology, fungal etiology, to know extent of polyposis and anatomical variations to prevent complications during FESS and Navigation sinus surgery.

Mikulicz, Lothrop and Claoué are considered to have been the first to perform inferior meatal antrostomy of the maxillary sinus. Siebenmann was apparently the first to recommend suprameatal antrostomy in the middle meatus, which is now fashionable again. Grünwald, Hajek, Killian, Halle and Uffenorde developed endonasal ethmoid surgery to an established procedure. PMID:2228741

    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

    We report a case of a 56-year-old man referred by his family physician with an asymptomatic cardiac murmur. 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

    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

    2008-01-01

    Introduction Acute sinusitis is defined pathologically, by transient inflammation of the mucosal lining of the paranasal sinuses lasting less than 4 weeks. Clinically, it is characterised by nasal congestion, rhinorrhoea, facial pain, hyposmia, sneezing, and, if more severe, additional malaise and fever. It affects 1−5% of the adult population each year in Europe. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments in people with clinically diagnosed acute sinusitis, and with radiologically or bacteriologically confirmed acute sinusitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to August 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 19 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics (amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides, different doses [amoxicillin, co-amoxiclav, doxycycline, cephalosporins, macrolides], long-course regimens), antihistamines, cephalosporins or macrolides, decongestants (xylometazoline, phenylephrine, pseudoephedrine), doxycycline, saline nasal washes, steam inhalation, and topical corticosteroids (intra-nasal).

  20. Relationship of optic neuritis to disease of the paranasal sinuses.

    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. PMID:6492975

    CT virtual reality using volumetric rendering can tag such structures as the nasofrontal ducts, osteomeatal complexes, the middle turbinates, as well as the planned surgical sites in patients undergoing endoscopic surgery for inflammatory disease. Frequently, anatomical landmarks are obscured by overlying disease, making the endoscopic surgeon's job difficult. We have evaluated the use of CT virtual reality of the paranasal sinuses in assisting the surgeon in these types of cases. This paper reviews 25 patients with 40 sites with significant paranasal sinus disease in whom endoscopic surgery was planned. The ability of volumetric virtual reality with the various surgical sites chosen from the preoperative 2D CT's dramatically improved the accuracy of the endoscopic surgeon in localizing their surgical window. In the sphenoid sinus, the addition of CT endoscopy would have allowed the endoscopist to operate on the correct sinus an additional 28% of the time and help them miss vital structures in 25%. In the frontal sinus, CT endoscopy correctly directed the endoscopist to the correct sinus in an additional 44%. The results of this study indicate CT endoscopy may significantly improve the accuracy of endoscopic surgery into the frontal and sphenoid sinuses.

  3. Rapid-developed primary malignant myoepithelioma in the cavernous sinus: a case report

    PubMed Central

    2013-01-01

    Background Malignant myoepithelioma is a relatively rare malignant tumor occurring most frequently in the salivary glands. A few isolated cases have been described in other locations, including soft tissue, bone, lung, bronchus, oral cavity, nasopharynx, larynx, and maxillary sinus. Malignant myoepithelioma, however, is uncommonly involved within the cavernous sinus. To the best of our knowledge, this is the first report of malignant myoepithelioma arising from within the cavernous sinus. Case presentation Herein, we report a case of a 48-year-old woman who presented a 1-month history of diplopia and blepharoptosis as well as radiological evidence of a rapidly developing cavernous sinus tumor. The patient underwent a trans-sphenoidal biopsy and a histological diagnosis indicated a malignant myoepithelioma. After diagnosis, the tumor grew rapidly and her clinical condition deteriorated progressively. Therefore, a pterional craniotomy with partial tumor removal was performed. The patient’s clinical state was worsened, and she died two months after the initial operation. Because the malignant myoepithelioma could not be traced to an organ of origin, other than the cavernous sinus, this case was diagnosed as a primary intracranial malignant myoepithelioma. Conclusion The purpose of presenting this case report is to raise awareness among clinicians to consider malignant myoepithelioma as a differential diagnosis when a cavernous sinus mass is identified. Furthermore, an ideal management strategy for malignant myoepithelioma is not known and the prognosis seems to be unfavorable; therefore, more cases are needed to enhance our knowledge of the diagnosis, treatment, and prognosis of this rare intracranial lesion.

    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

    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

    Objective The importance of traumatic dural venous sinus injury lies in the probability of massive blood loss at the time of trauma or emergency operation resulting in a high mortality rate during the perioperative period. We considered the appropriate methods of treatment that are most essential in the overall management of traumatic dural venous sinus injuries. Methods We conducted a retrospective review of all cases involving patients with dural venous sinus injury who presented to our hospital between January 1999 and December 2014. Results Between January 1999 and December 2014, 20 patients with a dural venous sinus injury out of the 1,200 patients with severe head injuries who had been operated upon in our clinic were reviewed retrospectively. There were 17 male and 3 female patients. In 11 out of the 13 patients with a linear skull fracture crossing the dural venous sinus, massive blood loss from the injured sinus wall could be controlled by simple digital pressure using Gelfoam. All 5 patients with a linear skull fracture parallel to the sinus over the venous sinus developed massive sinus bleeding that could not be controlled by simple digital pressure. Conclusion When there is a linear skull fracture parallel to the sinus over the dural venous sinus or a depressed skull fracture penetrating the sinus, the surgeon should be prepared for the possibility of potentially fatal venous sinus injury, even in the absence of a hematoma.

    Internal jugular vein thrombosis (IJVT) is a rare condition associated with malignancy, coagulopathy, and trauma. The optimal management of any IJVT must be individualized and depends on the condition of the patient. Case Presentation. We report the case of a 42-year-old woman with a history of a first trimester spontaneous abortion. Apart from a tension-type headache, she had no neurological symptoms. She reported an incidental diagnosis of right-sided IJVT when she was evaluated for hyperthyroidism ultrasonographically. On ultrasonography, we observed bilateral jugular vein thrombosis. The patient was started on oral warfarin. Seven months later, when she was adequately anticoagulated, she developed a second thrombosis. According to the etiological workup, she had a mutation in the homozygous methylene tetrahydrofolate reductase (MTHFR) gene and reduced protein C levels and activity. Conclusion. This report illustrates an unusual presentation of a rare condition. In this case, the etiology was associated with the coagulopathy, which occurred despite adequate anticoagulation. PMID:25221687

    A single coronary artery (SCA) ostium is a rare finding. In the general population, the incidence of SCA is approximately 0.024%. We introduce a case of a warehouseman presenting with chest pain after a morning work. The exercise ECG showed ST segment depression in the V 1-4 leads. The coronary angiography procedure and the CT demonstrated an SCA dividing into the right coronary artery and left main coronary artery. We identified a borderline lesion in the distal left anterior descending artery with fractional flow reserve of 0.85. In our case, the coronary anomaly was considered at low risk of arrhythmia and sudden death, and the patient was, therefore, treated conservatively. PMID:26951439

    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.

    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.

    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

    A 35-year-old healthy male with no history of any past medical illness developed severe headache, vomiting and drowsiness while at high altitude (4,572 m) in the eastern Himalayan ranges. He was evacuated to a tertiary-care hospital where he was diagnosed to have cerebral sinus venous thrombosis (CSVT) on magnetic resonance imaging, with deep vein thrombosis (DVT) of his right popliteo-femoral vein on color Doppler study. Investigation for thrombophilia revealed protein S (PS) deficiency in this patient. Family screening revealed low levels of PS in two elder brothers. One brother had a history of 'stroke in young' at the age of 20 years with the other being asymptomatic. This established the hereditary nature of PS deficiency. We are not aware of any previously published report on hereditary PS deficiency combined with CSVT and DVT occurring at high altitude. However, 1 case of protein C deficiency with CSVT has been reported previously. PMID:18434709

    Chronic sinusitis is a burdensome disease that has substantial individual and societal impact. Although great advances in medical and surgical therapies have been made, some patients continue to have recalcitrant infections. Microbial biofilms have been implicated as a cause of recalcitrant chronic sinusitis, and recent studies have tried to better understand the pathogenesis of chronic sinusitis as it relates to microbial biofilms. Here, we provide an overview of biofilms in chronic sinusitis with emphasis on pathogenesis, treatment, and future directions. In addition, recent evidence is presented, elucidating the role of bitter taste receptors as a possible key factor leading to biofilm formation. PMID:26758863

    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

    Introduction A 59-year-old Caucasian woman presented with an acute onset of alexia, noticed whilst driving. She described how while she could read car number plates, she had lost the ability to read and understand words on roadside advertisements and car window stickers. Case presentation Neurological examination was unremarkable apart from the inability to read full words or sentences. Imaging of the brain, initially computed tomography, followed by magnetic resonance venography, confirmed a diagnosis of sigmoid sinus thrombosis with associated venous infarction. The patient's past medical history revealed that she had suffered an ischemic stroke and following investigation for this, had undergone a nephrectomy for renal cell carcinoma. This was complicated by postoperative deep venous thrombosis. She had a persistent polycythaemia that was managed with venesection, and recently she had been diagnosed with Behçet's disease. Prior to this presentation, she had recently stopped her prophylactic antiplatelet medication as she was due to undergo a total knee replacement for osteoarthritis. She was managed with weight-adjusted, low molecular weight heparin followed by oral anticoagulation, and made a good recovery from her symptoms. Conclusion This case illustrates a classical neurological syndrome, highlights the importance of cerebral venous and sinus thrombosis as a cause of stroke, and the importance of remaining vigilant to a person's changing risk of venous thrombosis with evolving comorbidity.

    A rare case of fracture of the coronoid process, sphenoid bone, zygoma, and zygomatic arch caused by a firearm is described. A 25-year-old man was hit in the face with a bullet, resulting in restricted mouth opening, difficulty chewing, and pain when opening the mouth. The clinical examination revealed a perforating wound in the right parotid region. A computed tomographic scan revealed a comminuted fracture of the left coronoid process with the bullet stopping in the intact left coronoid process. Treatment was bilateral coronoidectomy associated with speech therapy and was successful. Details of the clinical signs, computed tomography, treatment, and follow-up are presented. PMID:22134317

    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

    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.

    Summary Background: Extranodal nasal-type natural killer (NK)/T-cell lymphoma represents a rare entity, typically originating in the nasal cavity, palate or midfacial region. Signs and symptoms include non-specific rhinitis and/or sinusitis, nasal obstruction, epistaxis, facial swelling and development of deep necrotic ulceration in the midline of the palate, causing an oronasal defect. Differential diagnosis includes fungal infections, Wegener’s granulomatosis, tertiary syphilis, other non-Hodgkin’s lymphomas and malignant epithelial midline tumors. Case Report: We present a case of a 40-year-old man complaining of headache, facial pain, nasal congestion and fever. Examination revealed a large deep necrotic ulcer in the middle of the palate, presenting as an oronasal defect. Endoscopic rhinoscopy revealed crusts in the nasal cavities, moderate perforation of the nasal septum cartilage and contraction of the middle and inferior conchae. Computer tomography showed occupation of the maxillary sinuses, ethmoidal cells and sphenoidal sinus by a hyperdense soft tissue mass. Laboratory investigation revealed increased erythrocyte sedimentation rate. A wide excision of the lesion was performed. Histopathological and immunohistochemical evaluation established the diagnosis of extranodal nasal-type NK/T-cell lymphoma. The patient was treated with CHOP chemotherapy, involved-field radiotherapy and autologous bone marrow transplantation. A removable partial denture with obturator was fabricated and inserted to relieve problems caused by the oronasal defect. Conclusions: Extranodal nasal-type NK/T-cell lymphoma is a very aggressive, rapidly progressing malignant neoplasm with a poor prognosis, which can be improved by early diagnosis and combined treatment.

    We report the first described case of Arthrographis kalrae pansinusitis and meningitis in a patient with AIDS. The patient was initially diagnosed with Arthrographis kalrae pansinusitis by endoscopic biopsy and culture. The patient was treated with itraconazole for approximately 5 months and then died secondary to Pneumocytis carinii pneumonia. Postmortem examination revealed invasive fungal sinusitis that involved the sphenoid sinus and that extended through the cribiform plate into the inferior surfaces of the bilateral frontal lobes. There was also an associated fungal meningitis and vasculitis with fungal thrombosis and multiple recent infarcts that involved the frontal lobes, right caudate nucleus, and putamen. Post mortem cultures were positive for A. kalrae. PMID:11158158

    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.

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

In most cases, it is diagnosed clinically, however, using the characteristic imaging features including maxillary sinus outlet obstruction, sinus opacification, and sinus volume loss caused by inward retraction of the sinus walls. Obstruction of the maxillary ostium appears to play a critical role in the development of SSS. Treatment involves functional endoscopic surgery. PMID:23946747

    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

    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

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

    Meningiomas are known to be associated with female sex hormones. Worsening neurological symptoms or newly diagnosed meningiomas have been described in the context of elevated levels of sex hormones, for example, in pregnancy. To the authors' knowledge, tumor shrinkage after the normalization of hormones has not been described, even if it is known that neurological deficits due to meningioma compression may improve after giving birth. A 32-year-old female patient presented with severe headache and vision disturbances at the end of her second pregnancy. Magnetic resonance imaging revealed an extended mass at the lateral left-sided sphenoid wing that was suspected to be a meningioma. After delivery, the patient's symptoms improved, and MRI obtained 2 months postpartum showed significant shrinkage of the lesion. Significant tumor shrinkage can occur after pregnancy. Thus, repeat imaging is indicated in these patients. PMID:26162042

    Each year we treat several patients with an anterior perineal sinus tract. They do not conform to commonly encountered perineal problems such as pilonidal disease, epidermal cysts, hidradenitis, fistulous abscess, or inflammatory bowel disease. In an effort to improve understanding of the problem and its clinical significance, we reviewed our practice records for the period from 1968 through 1988. Fifty-six patients underwent surgery for an anterior perineal sinus tract. In 31 patients, the clinical and pathologic condition defied classical diagnostic categorization. We have termed these lesions "anterior perineal sinuses." Their clinical characteristics, treatment, and pathologic assessment from the body of this report. Male predominance (87 percent) and midlife presentation (average age, 44 years) characterized this group. Local symptoms were present from several weeks to several years prior to treatment. Local anesthesia (74 percent) and limited surgery (100 percent) resulted in complete healing in all patients (average, 7 weeks). A 15 percent recurrence rate was noted. The pathologic evaluation demonstrated acute and chronic dermal and subcutaneous inflammation. The etiology of this process remains uncertain. Its predominance along the median raphe suggests a congenital midline inclusion disorder. PMID:1914743

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. PMID:26183855

Primary central nervous system lymphoma is uncommon, accounting for approximately 2% of all primary intracranial tumors, but its incidence has been steadily increasing in some groups [1]. It usually arises in the periventricular cerebral white matter, and reports of lymphoma in extra-axial regions are rare [2]. This man highlights the importance of maintaining lymphoma in the differential diagnosis of tumors of the skull base presenting with trigeminal neuralgia-like symptoms. PMID:25865026

    Subperiosteal orbital abscess (SPA) is a serious complication of paranasal sinusitis, which can lead to blindness or even death. A quick response is necessary as this condition is treatable. Early surgical intervention is indicated if there is risk of visual loss, or if no improvement is observed within 48 hours of starting medical therapy. Three patients with orbital SPA secondary to sinusitis treated successfully by Functional Endoscopic Sinus Surgery (FESS) are presented in this case series. The surgical indications were impending visual loss with an abscess and cellulitis impinging on the optic nerve in one child and in the other two patients, a lack of clinical response within 48 hours after starting systemic antibiotic. CT scans, nasal endoscopy, and ophthalmologic examinations are mandatory during the evaluation process. The advantages of FESS in these patients were the avoidance of external ethmoidectomy and its external facial scar, an early drainage of the affected sinuses, SPA, and the eradication of the disease from the fronto-ethmoidal region leading to an enhanced recovery and a reduced hospital stay. FESS is also a safe, convenient and minimally invasive procedure in patients presenting with serious complications of sinusitis. PMID:11721506

    2013-11-01

    Chronic sinusitis is a common disease that encompasses a number of syndromes that are characterized by sinonasal mucosal inflammation. Chronic sinusitis can be defined as two or more of the following symptoms lasting for more than 12 consecutive weeks: discolored rhinorrhea, postnasal drip, nasal obstruction, facial pressure or pain, or decreased sense of smell. Chronic sinusitis is further classified as chronic sinusitis with polyposis, chronic sinusitis without polyposis, or allergic fungal sinusitis using physical examination, and histologic and radiographic findings. Treatment methods for chronic sinusitis are based upon categorization of the disease and include oral and inhaled corticosteroids, nasal saline irrigations, and antibiotics in selected patients. Understanding the various forms of chronic sinusitis and managing and ruling out comorbidities are key to successful management of this common disorder. PMID:24192597

    SUMMARY Maxillary sinus floor elevation is generally accepted as a regenerative procedure to facilitate dental implants placement in the posterior atrophic maxilla. Although the sinus lift procedure is relatively safe, some potential problems could be occur. The most prevalent intraoperative complication is perforation of sinus membrane, which can lead to graft infection and early failure. The Aim of this work Is to present a new technique to repair large perforation of sinus membrane. This case report Is focused on a 10 mm perforation of sinus membrane occurred during preparation of the sinus window. The obliteration of the perforation was obtained by means of suturing sinus membrane with a resorbable material to the bone directly lateral to the osteotomy site. Sinus augmentation procedure could complete and the insertion of a graft was permitted. PMID:23991280

    Expanded indications for cardiac resynchronization therapy and the increasing incidence of cardiac implantable electronic device infection have led to an increased need for coronary sinus (CS) lead extraction. The CS presents unique anatomical obstacles to successful lead extraction. Training and facility requirements for CS lead extraction should mirror those for other leads. Here we review the indications, technique, and results of CS lead extraction. Published success rates and complications are similar to those reported for other leads, although multiple techniques may be required. Re-implantation options may be limited, which should be incorporated into pre-procedural decision making. PMID:26596810

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

    Congenital coronary sinus anomalies are rare in clinical practice, partly due to the lack of symptoms. We present a case of coronary sinus anomaly causing a right-to-left intracardiac shunt in a 46 years/old African American female with a past medical history of obstructive sleep apnea, diabetes mellitus, hypertension, coronary artery disease, and ischemic cardiomyopathy who presented with hypoxia. In the months prior to her presentation, she had suffered an inferior myocardial infarction with right ventricular involvement, as well as resulting severe tricuspid regurgitation. In conclusion, further investigations revealed a communication between the coronary sinus (CS) and left atrium (LA). PMID:19730747

    A 75-year-old man was admitted to our hospital because of repeated transient visual obscurations of greying vision. The transient visual obscurations were caused by rotating his neck or the Valsalva manoeuver, and they recovered in about 30 seconds. A few weeks later, pulsatile tinnitus of the right ear and a dull headache developed. Both ocular fundi showed papilledema, and there was significant intracranial hypertension on cerebrospinal fluid examination. He was diagnosed as having right sigmoid sinus thrombosis and a dural arteriovenous fistula with a rapid arteriovenous shunt from the right ascending pharyngeal artery and the right occipital artery to the right transverse sinus. Anticoagulant therapy was started, and coil embolization was performed. The transient visual obscurations, headache, and tinnitus improved dramatically after the procedure. We hypothesized that the transient visual obscurations were triggered by rotating the neck or performing the Valsalva manoeuver as they both increase the pressure of cerebrospinal fluid, inducing transient optic nerve ischemia and visual obscurations under mild intracranial hypertension. Transient visual obscurations are an important initial symptom of intracranial hypertension. PMID:27010097

    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.

    Most sinus infections are viral, and only a small proportion develops a secondary bacterial infection. Rhinoviruses, influenza viruses, and parainfluenza viruses are the most common causes of sinusitis. The most common bacteria isolated from pediatric and adult patients with community-acquired acute purulent sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes. Staphylococcus aureus and anaerobic bacteria (Prevotella and Porphyromonas, Fusobacterium and Peptostreptococcus spp.) are the main isolates in chronic sinusitis. Pseudomonas aeruginosa and other aerobic and facultative gram-negative rods are commonly isolated from patients with nosocomial sinusitis, the immunocompromised host, those with HIV infection, and in cystic fibrosis. Fungi and Pseudomonas aeruginosa are the most common isolates in neutropenic patients. The microbiology of sinusitis is influenced by the previous antimicrobial therapy, vaccinations, and the presence of normal flora capable of interfering with the growth of pathogens. PMID:21364226

    Sinus barotrauma, secondary to mucosal disturbances, is a common finding within the aviation community. Multiple etiologies have all led to mucosal inflammation and thickening with potential obstruction of the sinus osteomeatal complex, especially during the barometric changes of flight. Obstruction can, therefore, lead to problems with sinus pressure equilibration with atmospheric pressure, and can lead to barosinusitis. We present a case of a U.S. Air Force Command Pilot with acute left sinus barotrauma during descent while flying a T-37 aircraft, along with a brief review of the pathophysiologic processes involved during barotrauma. An inflammatory polyp within his sinus was identified by plain radiography, confirmed with computed tomography, and subsequently excised. The patient had complete resolution and clearance to fly after an uneventful 4-wk convalescence and altitude chamber flight. This is the first case of sinus barotrauma secondary to an inflammatory maxillary sinus polyp, confirmed by histologic diagnosis, reported in the aeromedical literature. PMID:12433240

    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

    AIM To determine the clinical features of the dacryoadenitis subtype of idiopathic orbital inflammatory pseudotumor and its relationship with paranasal sinusitis. METHODS A retrospective analysis of 46 patients who received surgical treatment at the Department of Ophthalmology, Beijing Tongren Hospital, Capital Medical University for the dacryoadenitis subtype of idiopathic orbital inflammatory pseudotumor from October 2010 to December 2012. Each patient underwent magnetic resonance imaging (MRI) of the orbits and the 4 paranasal sinuses. Disease status and the level of serum immunoglobulin G4 (IgG4) was measured before and 6mo after surgery. RESULTS The initial clinical feature of the idiopathic dacryoadenitis type of orbital inflammatory pseudotumor was redness or swelling of the eyelids. Masses were palpated in the area of the lacrimal gland in some patients. Of the 46 patients, 16 also suffered from sinusitis (34.8%), with 14 cases of ethmoid sinusitis, 8 cases of maxillary sinusitis, 9 cases of sphenoid sinusitis, and 8 cases of frontal sinusitis. Of the 16 patients with sinusitis, 4 patients had a medical history of rhinitis (range: 10mo to 15y previously), 10 patients had occasional nasal congestion, and 2 patients had no nasal congestion. Thirteen of the 46 patients had elevated serum IgG4 levels. Nine of these 13 patients had MRI signs of sinusitis. All patients (n=46) received oral glucocorticoid treatment for approximately 3mo after surgery. No sign of recurrence was found in the orbital MRI 6mo after surgery. Of the 16 patients with sinusitis, 9 cases of elevated serum IgG4 levels improved after treatment with decreased serum IgG4 level and 7 cases of normal serum IgG4 levels remained unchanged. CONCLUSION Some patients with the dacryoadenitis subtype of idiopathic orbital inflammatory pseudotumor may also suffer from paranasal sinusitis. The incidence of paranasal sinusitis was much higher in patients with IgG4-elevated dacryoadenitis subtype orbital

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

    The significance of nasal resonance and anti-resonance to voice production is a classical issue in vocal pedagogy and voice research. The complex structure of the nasal tract produces a complex frequency response. This complexity must be heavily influenced by the morphology of the paranasal cavities, but their contributions are far from being entirely understood. Detailed analyses of these cavities are difficult because of their limited accessibility. Here we test different methods aiming at documenting the acoustical properties of the paranasal tract. The first set of experiments was performed under in vivo conditions, where the middle meatus was occluded by means of targeted application of a maltodextrin mass under endoscopic control. The efficiency of this occlusion method was verified by measuring the nasal nitric oxide (NO) output during humming. In another experiment the frequency responses to sine sweep excitation of an epoxy mould of a nasal cavity were measured, with and without elimination of paranasal sinuses. The third experiment was conducted in a cadaveric situs, with and without maltodextrin occlusion of the middle meatus and the sphenoidal ostia. The results show that some nasal tract resonances were unaffected by the manipulation of the paranasal cavities. Providing access to a maxillary sinus resulted in marked dips in the response curve while access to the sphenoidal ostium caused only minor effects. PMID:25327481

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

    Pleomorphic adenoma is the most common type of benign salivary gland tumor. It can also be found in the larynx, ear, neck, and nasal septum. It is rarely found in the maxillary sinus, and it has never been reported in the frontal sinus. We report a case of pleomorphic adenoma of the frontal sinus that masqueraded as a mucocele. We discuss the clinical presentation, diagnosis, and treatment of this patient, and we review the literature. PMID:26670764

    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

    The intracranial venous sinus is an important component of vascular disease. Many diseases involve the venous sinus and are accompanied by venous sinus stenosis (VSS), which leads to increased venous pressure and high intracranial pressure. Recent research has focused on stenting as a treatment for VSS related to these diseases. However, a systematic understanding of venous sinus stenting (VS-Stenting) is lacking. Herein, the literature on idiopathic intracranial hypertension (IIH), venous pulsatile tinnitus, sinus thrombosis, high draining venous pressure in dural arteriovenous fistula (AVF) and arteriovenous malformation (AVM), and tumor-caused VSS was reviewed and analyzed to summarize experiences with VS-Stenting as a treatment. The literature review showed that satisfactory therapeutic effects can be achieved through stent angioplasty. Thus, the present study suggests that selective stent release in the venous sinus can effectively treat these diseases and provide new possibilities for treating intracranial vascular disease.

    Orbital emphysema is usually caused by trauma and fracture of an orbital bone, allowing air to pass from the sinuses into the orbit. Orbital emphysema without any significant trauma is rare. We present a case of a 67-year-old-woman who complained of left exophthalmos without any history of trauma, sneezing, or sinus surgery. Computed tomography scanning showed left orbital emphysema protruding the eyeball forward. The left frontal sinus was remarkably enlarged associated with a partial defect of the orbital roof, allowing air entry into the orbit. In addition, the frontal sinus ostium was occluded with the mucocele that served as a one-way valve between the frontal and the ethmoidal sinuses. We performed frontal craniotomy and removed the mucocele and the inner table of frontal bone to communicate the frontal sinus with the nasal cavity. After operation, her exophthalmos was improved.

    Trichomonal disease typically involves the genital and occasionally respiratory tracts. Although exposure of the upper respiratory tract to infected genital secretions is not uncommon with contemporary sexual practices, trichomonal sinus disease has been rarely described. The present report describes the case of a healthy 17-year-old male admitted to an intensive care unit following multiple trauma, who developed purulent sinusitis on the 4th day of hospitalization. Numerous trichomonads were noted on microscopic examination of sinus aspirate. Further investigation revealed orofacial sexual exposure of the patient to a partner with trichomoniasis. The patient's sinusitis resolved following a course of parenteral metronidazole-containing antibiotics. PMID:19204647

    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

    In the literature, clinical descriptions of sigmoid sinus thrombosis occurring after closed head injury in children are rare. One to 5 days after trauma to the back of the head, five children (aged 1 to 7 yr) presented with gait ataxia, vomiting, and headache. Trauma was mild in four children. Computed tomography of all the children, performed within 5 days after the injury, showed focal hyperdensity in the region of the left sigmoid sinus. Four children had extra-axial hyperdense collections along the left transverse sinus, and three had skull fractures adjacent to the left sigmoid sinus. Magnetic resonance imaging (MRI) of all the children, performed 2 to 6 days after injury, showed left sigmoid-sinus thrombosis and decreased flow or thrombosis within the lateral third of the left transverse sinus. All the children had MRI scans 4 to 6 weeks after their diagnosis and were followed up for 1 to 12 months. In four children whose symptoms subsided completely within 2 to 10 weeks, MRI showed recanalization of the sigmoid sinus within 4 to 6 weeks after injury. In one child whose symptoms resolved after 6 months, sigmoid-sinus thrombosis persisted with the formation of collateral flow. We conclude that traumatic sigmoid-sinus thrombosis should be suspected when a child has persistent or delayed gait ataxia and vomiting after injury to the back of the head. Computed tomography characteristically demonstrated focal hyperdensity within the sigmoid sinus that we term the dense sigmoid-sinus sign. Because the sinus recanalized and the symptoms subsided in most children within 6 weeks, we conclude that prophylactic medical or surgical intervention is not indicated. PMID:8474644

    This study evaluates the most extensive long-term treatment outcome of paranasal sinus mucocoeles with particular emphasis on the efficacy of endonasal micro-endoscopic management. It is a retrospective, consecutive case review of 255 patients with 290 mucocoeles including 125 frontal sinus, 23 frontoethmoid, 41 ethmoid, 72 maxillary sinus and 26 sphenoid mucocoeles. The median follow-up of the patients is 12 years (range 1 - 19 years). Sixtysix percent of the mucocoeles resulted after previous sinus surgery, whereas only 1.5% developed after endonasal micro-endoscopic surgery. The median period until mucocoele appearence was 10.8 years. Two hundred one mucocoeles (69.3%) were managed endonasally micro-endoscopically, 18.6% via the osteoplastic approach, 10% endoscopically in combination with an osteoplastic procedure, and 2% according to Lynch/Howarth. Thereafter, recurrence was found in 4 patients only (2.2%). In relation to the endonasal approach the recurrence rate was 1.6%. None of the patients treated endonasally had any complication. In view of these results this paper verifies endonasal micro-endoscopic surgery as a reliable treatment with favourable long-term outcome for paranasal sinus mucocoele management, but also describes contraindications for an endonasal procedure.

    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

    2000-01-01

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

    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

    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.

    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.

    2013-01-01

    High-resolution X-ray computed tomographic scans were used to examine pterygoid sinus morphology within extant porpoise species and one delphinid (Tursiops truncatus), in order to consider: 1) intraspecific and interspecific variation among the studied species; 2) the most parsimonious sequence of character acquisition; and 3) the potential functional roles of the preorbital lobes of the sinuses in sound reflection. Scans revealed that the pterygoid/palatine regions are mediolaterally broader in the earliest diverging phocoenid (Neophocaena phocaenoides) and Tursiops truncatus than the dorsoventrally elongated sinuses observed in other species. Rostrocaudal lengths of the sphenoidal regions of the sinuses in all individuals studied are proportionally similar, indicating conservatism in this region across species. The neonate Phocoena phocoena has shorter preorbital lobes than adults, but they are still proportionally longer than Neophocaena phocaenoides and Phocoena spinipinnis. The preorbital lobes broaden mediolaterally to varying degrees across species; in particular, Phocoenoides dalli has the largest dorsal and lateral expansion of this region. Assuming the highest pulse frequency produced by porpoises is 150 kHz, all regions of the preorbital lobes are thick enough to reflect the wavelengths produced. In addition, the neonate preorbital lobes are not as elongated as they are in adults, and the dorsal third of this region may not reflect sound to the same extent. This study reinforces the importance of using nondestructive methods to quantify variation in endocranial anatomy and the value of CT data for recovering phylogenetically useful information, as well as functional roles sinuses play in concert with the soft tissue head anatomy for biosonar.

    To study MR patterns of venous sinus occlusive disease and to relate them to the underlying pathophysiology by comparing the appearance and pathophysiologic features of venous sinus occlusive disease with those of arterial ischemic disease. The clinical data and MR examinations of 26 patients with venous sinus occlusive disease were retrospectively reviewed with special attention to mass effect, hemorrhage, and T2-weighted image abnormalities as well as to abnormal parenchymal, venous, or arterial enhancement after intravenous gadopentetate dimeglumine administration. Follow-up studies when available were evaluated for atrophy, infraction, chronic mass effect, and hemorrhage. Mass effect was present in 25 of 26 patients. Eleven of the 26 had mass effect without abnormal signal on T2-weighted images. Fifteen patients had abnormal signal on T2-weighted images, but this was much less extensive than the degree of brain swelling in all cases. No patient showed abnormal parenchymal or arterial enhancement. Abnormal venous enhancement was seen in 10 of 13 patients who had contrast-enhanced studies. Intraparenchymal hemorrhage was seen in nine patients with high signal on T2-weighted images predominantly peripheral to the hematoma in eight. Three overall MR patterns were observed in acute sinus thrombosis: (1) mass effect without associated abnormal signal on T2-weighted images, (2) mass effect with associated abnormal signal on T2-weighted images and/or ventricular dilatation that may be reversible, and (3) intraparenchymal hematoma with surrounding edema. MR findings of venus sinus occlusive disease are different from those of arterial ischemia and may reflect different underlying pathophysiology. In venous sinus occlusive disease, the breakdown of the blood-brain barrier (vasogenic edema and abnormal parenchymal enhancement) does not always occur, and brain swelling can persist up to 2 years with or without abnormal signal on T2-weighted images. 34 refs., 5 figs.

    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.

    2013-01-01

    Silent Sinus Syndrome (SSS) is known to be a rare clinical condition, characterized by spontaneous and progressive enophthalmos and hypoglobus associated with atelectasis of the maxillary sinus and alteration of the orbital floor. Most of the patients with this syndrome present with ophthalmological complaints without any nasal sinus symptoms, and it typically has a painless course and slow development, ergo the term “silent.” Here we present a case report of a patient with occasional coughing spells as the presenting symptom of Silent Sinus Syndrome, which has not been previously described in the literature. The CT scan findings suggested chronic rhinosinusitis. The radiological findings were suggestive of maxillary sinus hypoplasia, with evidence of maxillary sinus atelectasis. Awareness of this syndrome is important for specialists who work with nasal sinus disease, since its management is different than chronic rhinosinusits. PMID:24321328

    In summary, cavernous sinus thrombosis is still with us. Patients now survive the disease more often than not, and therapy and diagnosis are reasonably clear cut. An increasing array of antibiotic-resistant bacteria have been balanced by an increasing army of antibiotics. The controversy over anticoagulation has not changed since reviewed by Parsons (1967). Ancillary measures remain more of value in diagnosis than in therapy. It is a disease primarily diagnosed by physical signs and symptoms, which requires prompt treatment. In our modern age of computerization and laboratory-based medical care, cavernous sinus thrombosis demands the diagnostic skill of the clinician, whose prompt ministrations should usually yield a favourable result.

She has a history of "root canal therapy" five years before. Physical examination found purulent secretion in the right middle nasal meatus, and light tenderness in the right side of the maxillary sinus area. The CT scan of paranasal sinus shown possible fungal infection of right maxillary sinus. Finally the nasal endoscopic surgery confirmed the fungus ball of right maxillary sinus with foreign body (the root canal filling material). PMID:26685411

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

    2016-01-01

    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.

    Although sinus lift procedures are reliable, some complications can lead to serious maxillary sequelae, including the development of oro-antral fistula (OAF). Maxillary reconstruction in such patients presents a challenge owing to sinus floor alterations, graft remnants, chronic infection, and morbidity from the original sinus lift approach. The current study describes our technique of maxillary reconstruction using a Le Fort 1 approach following major sinus lift complications with associated residual OAF. This technique provides excellent access for sinus curettage, OAF closure, and osseous reconstruction. It allowed a successful rehabilitation in our patients, with no implant loss and good functional and esthetic results. PMID:26825748

    Objectives To describe outcomes of endoscopic resection of sellar tumors with concomitant endoscopic sinus surgery for patients with chronic rhinosinusitis (CRS). Design Retrospective chart review. Setting Tertiary care medical center. Participants Patients who underwent endoscopic transsphenoidal surgery for excision of anterior skull base lesions and simultaneous functional endoscopic sinus surgery (FESS) for CRS between January 2006 and January 2011 by senior authors (MRR and JJE). Main Outcomes Measured Short- and long-term postoperative complications. Results Fourteen patients were identified. Average follow-up was 27 months. All patients had preoperative symptoms consistent with CRS. No patients were treated with preoperative antibiotics. Surgical pathology revealed chronic sinusitis in all specimens. Pathology of the intracranial lesions included 11 pituitary macroadenomas, one craniopharyngioma, one chondrosarcoma, and one cholesterol granuloma. Short-term postoperative morbidities included a sphenoid polyp, one adhesion, and one case of pharyngitis. Long-term outcomes included one frontoethmoidal mucocele, one recurrence of nasal polyps, and three cases of acute sinusitis. There were no intracranial complications for the entire follow-up period. Conclusions Transsphenoidal surgery can safely be performed in the setting of CRS without increased risk of intracranial complications. PMID:24436919

    Sixty-one chronically inflamed maxillary sinuses produced 131 bacterial strains from mucosal pieces that were taken during a Caldwell-Luc operation and cultured aerobically and anaerobically. Sinus secretions showed only 62 and nasal secretions 106 bacterial strains. Fourteen mucosal strains, including 11 Haemophilus influenzae, grew heavily. None of 24 mucosal anaerobes showed heavy growth. Of 52 antral mucosae with culturable bacteria, 37 disclosed mixed and 15 pure growth. The bacteriological characteristics of the diseased sinus and the nose did not correlate. The duration or extent of the disease, the macroscopic appearance of the diseased sinus, or the presence or absence of allergy were unrelated to bacteriological findings, except that H influenzae was concentrated in purulent sinuses. Intraoperative culture of antral mucosa seems to give the most reliable picture of the bacteriological condition in chronic maxillary sinusitis. PMID:313206

    We reported our experience using diode laser under microscope to resect a sphenoidal crest, orbit and infratemporal fossa communicative meningioma through fronto-tempo-preauricular approach. We used contacting, un-contacting and inserting methods and the power was in the range of 5 - 30 watt. The tumor was totally removed and the patient received radiotherapy post- operation. Follow up showed that the patient survived for two years after operation. The result showed that combination of laser application during surgery and radiotherapy post-operation was an effective method to delay or prevent tumor recurrence.

    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. PMID:25209225

    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

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

    The frontal sinus can present a challenging surgical dissection for the endoscopic surgeon. Image guidance as a surgical adjunct has become widely accepted for surgeries in this area. It can help verify vital structures and manage disorienting surgical conditions, improving surgeon confidence in performing safer and more complete surgery. It is relied upon heavily for placement of limited external frontal sinusotomies for disease beyond the endoscopic reach, and for mapping the frontal sinus for osteoplastic flap bony cuts. Its use has contributed to the expanding role of endoscopic surgical approaches for paranasal sinus inflammatory and neoplastic disease. PMID:27329979

    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.

    Introduction: Seizure involves less than 1% of pregnancies; however it is associated with increased maternal and fetal complications. Cerebral venous sinus thrombosis is a rare, but potentially life-threatening cause of seizure during pregnancy, presenting primarily as seizure in 12% - 31.9% of cases. Pregnancy and puerperium are known as the risk factors of cerebral venous sinus thrombosis. Case Presentation: Here is presented a case of seizure after delivery by cesarean section in an otherwise healthy woman. The final diagnosis was cerebral venous sinus thrombosis probably due to hypercoagulable state in pregnancy. Conclusions: If seizure occurs during the peripartum period, along with providing complete cardiovascular and respiratory support, advanced diagnostic measures are needed and cerebral venous sinus thrombosis should be considered as a possible diagnosis.

    Primary site control, anatomical site of failure, survival, and complications of treatment were determined in a retrospective review of primary maxillary sinus carcinoma. Sixty-one patients were treated by radiation followed by surgery and 35 by radiation alone. Primary tumor control was achieved in 69% of patients receiving combined treatment, 14% of patients treated with radiation alone, and 49% of all patients. Local control did not differ with histological type. Virtually all epidermoid and undifferentiated carcinoma recurrences occurred within 2 years, but 27% of adenocarcinomas recurred after 2 years.

    Bone tissue atrophy may constitute a relative contraindication for implantation. The methods used in reconstruction of the alveolar ridge within the lateral section of the maxilla have been well known but not perfect. Presentation of the two-stage, closed sinus lift technique as well as efficacy evaluation of reconstruction of the alveolar ridge in the maxilla within its vertical dimension with the use of this technique. The total procedure was performed in 26 out of 28 patients qualified for the study. The height of the alveolar ridge at the site of the planned implantation was no <3 mm, the width of the ridge was no <5 mm. During the treatment stage 1 the sinus lift was performed for the first time. The created hollow was filled with allogeneic granulate. After 3-6 months stage 2 was performed consisting in another sinus lift with simultaneous implantation. The treatment was completed with prosthetic restoration after 6 months of osteointegration. In 24 out of 26 cases stage 1 was completed with the average ridge height of 7.2 mm. In stage 2, simultaneously with the second sinus lift, 26 implants were placed and no cases of sinusitis were found. In the follow-up period none of the implants were lost. The presented method is efficient and combines the benefits of the open technique-allowing treatment in cases of larger reduction of the vertical dimension and the closed technique-as it does not require opening of the maxillary sinus.

    Cerebral venous sinus (sinovenous) thrombosis (CSVT) is a rare life-threatening disorder in childhood that is often misdiagnosed. CSVT encompasses cavernous sinus thrombosis, lateral sinus thrombosis, and superior sagittal sinus thrombosis (SSST). We present an adolescent girl who was well until two weeks earlier when she had a throbbing frontal headache and fever with chills; she later had dyspnoea, jaundice, melena stool, multiple seizures, nuchal rigidity, and monoparesis of the right lower limb a day before admission. Urine test for Salmonella typhi Vi antigen was positive, and Widal reaction was significant. Serial cranial computerized tomography scans revealed an expanding hypodense lesion in the parafalcine region consistent with SSST or a parasagittal abscess. Inadvertent left parietal limited craniectomy confirmed SSST. She recovered completely with subsequent conservative management. Beyond neuropsychiatric complications of Typhoid fever, CSVT should be highly considered when focal neurologic deficits are present. PMID:23227403

    Paranasal sinus cancers are rare, aggressive tumours that are usually diagnosed at an advanced stage. They differ from other upper aerodigestive tract tumours in terms of risk factors (wood dust exposure) and premalignant lesions (inverted papillomas). The diagnosis should be suspected in the presence of unilateral and continuous nasal sinus symptoms or bone lysis or a heterogeneous opacity on imaging. The definitive positive diagnosis is based on histological examination. Staging must comprise face, brain, neck and chest CT as well as face and brain MRI. Tumours are stage T3-T4 in two-thirds of cases and are associated with cervical lymph node involvement in 10% of squamous cell carcinomas and 4% of adenocarcinomas. These tumours must be managed in reference centres experienced in all of the various treatment modalities. Treatment decisions must be based on a multidisciplinary approach comprising local, regional and national REFCOR expertise (French rare head and neck cancer network). Optimal treatment is surgical resection with clear margins associated with adjuvant intensity-modulated radiotherapy (IMRT). Although it has been improved over recent decades, the prognosis remains poor with local recurrences occurring in 38% of cases and a five-year overall survival of about 63%. PMID:23523040

    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

    Subperiosteal hematoma of the orbit is a rare but well-recognized entity, usually caused by trauma. Two cases of subperiosteal hematoma associated with sinusitis are presented. A 44-year-old woman experienced the sudden onset of proptosis, and decreased visual acuity. Computed tomographic scanning and magnetic resonance imaging revealed a frontoethmoidal mucocele and a biconvex mass in the upper part of the left orbit. The mucocele was drained during nasal endoscopic surgery and the subperiosteal hematoma was evacuated during superior orbitotomy. A 42-year-old man had a headache and proptosis. Computed tomographic scan revealed sinusitis and subperiosteal orbital hematoma of the left orbit. Subperiosteal orbital hematoma associated with sinusitis is extremely rare but should be suspected in a patient with acute onset of proptosis in whom computed tomographic scanning reveals paranasal sinusitis.

    Lyme disease is the most prevalent tick-borne disease in the United States. It is caused by the spirochete Borrelia burgdorferi. Cardiac involvement is seen in 4% to 10% of patients with Lyme disease. The principal manifestation of Lyme carditis is self-limited conduction system disease, with predominant involvement of the atrioventricular node. On rare occasions, Lyme carditis patients present with other conduction system disorders such as bundle branch block, intraventricular conduction delay, and supraventricular or ventricular tachycardia. We report the unusual case of a 59-year-old man who presented with new-onset symptomatic sinus pauses one month after hiking in upstate New York. To our knowledge, this is the first case report from North America that describes the relationship between symptomatic sinus pause and Lyme carditis. PMID:26175640

    The most common primary tumors of the frontal sinus are osteomas and inverted papillomas, although a variety of other tumors involving this space have been reported. With the advent of new surgical techniques and instrumentation, an endoscopic approach to this region has become feasible. The preoperative assessment and decision making must take into account the complexity of frontal sinus anatomy, tumor type, tumor location, and associated attachments. These procedures allow adequate visualization, tumor removal, and postoperative monitoring, and preserve fairly normal sinus function. Open techniques may also be required and should be in the surgeon's armamentarium. PMID:27450620

    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.

    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. PMID:25487178

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

    Sinus-vein thrombosis is increasingly recognized as a much more frequent neurological disorder than was anticipated before. We examined the pathophysiology of superior sagittal sinus thrombosis (SSST) from 19 patients and a rat SSST model. We treated 19 cases with SSST who were diagnosed by angiography. The symptoms of nine patients, who suffered multiple intracerebral hemorrhage, were abrupt. In another ten patients who recovered satisfactorily, the condition progressed slowly and they were treated with heparin and urokinase. Multivariate analysis demonstrated that female, sudden onset (<24 hours) and posterior 1/3 occlusion are related to bad outcome. Experimentally, SSST was induced by ligation and slow injection of kaolin-cephalin suspension into SSS in rats. Regional cerebral blood flow (rCBF) and tissue hemoglobin oxygen saturation (Hb Sao2) using a “scanning” technique were measured at 48 locations, and fluorescence angiography was performed before and until 90 min after SSST induction. After 48 hours the animals were sacrificed for histological studies. Decrease of rCBF and tissue Hb SO2 and brain damage were seen in group B (n = 10) with an extension of thrombosis from SSS into cortical veins. Brain injury was not observed in group A (n = 8) with SSS thrombus alone and sham-operated animals (n = 5). In conclusion, a brain with acute extension of thrombus from SSS into cortical veins becomes critical for cerebral blood supply and metabolism. CBF, tissue HbSO2 and repeated angiography can be helpful monitors for the early detection of critical conditions after SSST. As to the therapy, restraint on the ongoing thrombus is essential to protect the brain with SSST, and we encourage the use of combination therapy of heparin and urokinase as early as possible in cases without intracerebral hemorrhage.

    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.

    Treatment of frontal sinus using surgery is complicated owing to the complex anatomical structure of the sinus region. The aim of the present study was to investigate the efficacy and safety of Draf IIb endoscopic frontal sinus surgery treatment for frontal sinus lesions using the agger nasi approach on 19 patients (28 left or and right nasal cavities). A 10–12 mm excision of the upper frontal maxilla was performed for endoscopic resection between the middle turbinate and lateral nasal wall. No serious complications in frontal sinus surgery treatment for the removal of the frontal sinus were observed. Patients were followed up after surgery for 6–36 months. Chronic sinusitis and nasal polyps were identified in 10 cases (19 left or and right nasal cavities; disease control, 15 left or and right nasal cavities; and disease partial control, 4 left or and right nasal cavities). Frontal sinus inverted papilloma was observed in 9 cases (9 left or and right nasal cavities). Frontal sinus inverted papilloma were successfully treated in 8 cases, and 1 case of recurrence was observed. In conclusion, the nasal endoscopic Draf IIb agger nasi approach is a minimally invasive treatment for frontal sinus lesions. This surgical procedure is safe and less complicated and may be applied in the clinic.

    2015-01-01

    Background Congenital dermal sinus (CDS) is an uncommon form of spinal dysraphism. Although postdelivery identification in the neonate is aided by several associated physical examination findings, establishing this diagnosis prenatally has proven to be elusive. Case Report We present a case of CDS where the prenatal findings at 20 weeks gestation led to the diagnosis, which was confirmed postnatally. The associated protrusion of fibrotic membranes through the sinus tract helped in the identification of this lesion prenatally, but created confusion with a more common type of lesion, an open neural tube defect. This is the first case report in the literature describing prenatal diagnosis of fetal CDS. Conclusion Prenatal diagnosis with postnatal confirmation of CDS leads to early intervention, better long-term outcomes, and lesser complications. PMID:26199797

    A 76-year-old woman presented with symptoms suggestive of acute sinusitis. Previously, her breast carcinoma was treated with right lumpectomy, adjuvant chemotherapy and breast radiotherapy. She remained free from recurrence for the following 8 years. After initial treatment with antibiotics, the local symptom worsened with exophthalmos, eye blindness and development of an ulceration of the hard palate. MRI showed irregular enhancement of the nasal cavity extended to the maxillary sinus and ethmoidal lamina and concomitant infiltration of the orbit and skull base. A biopsy of the palatal ulcer showed a poorly differentiated adenocarcinoma and was compared with the histology of the primary breast tumour and it was concluded for the same morphology. After discussion at the multidisciplinary team, a specific chemotherapy has been activated with an initial local response. Further surgical resection was not thought appropriate and the patient has subsequently undergone palliative radiotherapy to the right paranasal lesions to improve local disease control.

    2013-01-01

    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

    A classification system for sinus membrane perforations encountered during a sinus augmentation procedure is presented. Five of the perforations are discussed, as are the therapeutic options for their repair. Class I and Class II perforations are most easily repaired, while Class IV is the most difficult to successfully treat. In addition, the effect of the sinus membrane perforation on the course of proposed therapy is discussed. When classified and managed appropriately, sinus membrane perforations are not an absolute indication for aborting the augmentation procedure which is in progress. This paper provides a system of classification that can be used by clinicians to collect data on membrane perforations and repair results. PMID:10397526

    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.

  5. Economic implications of chronic sinusitis.

    1998-03-01

    An approach to cost analysis useful in understanding the economic implications of surgical intervention on chronic sinusitis is break-even time analysis. The break-even time is the time until cost savings associated with improved health status after surgery equal the up-front costs of the operation itself. Data from 100 consecutive patients undergoing sinus operation were obtained by survey before surgery and at quarterly intervals for 1 year with statistically validated outcome measures (Medical Outcome Study Short Form 36-Item Health Survey, Chronic Sinusitis Survey). Direct and indirect costs were obtained or derived for this cohort. The cost of sinus medications, including over-the-counter remedies, nasal steroid sprays, and antibiotics, averaged $1220 per patient per year before surgery and $629 after surgery (p < 0.0001), which is a 48% reduction. Surgical costs averaged $6490 per patient. Economic modeling predicted a break-even time of approximately 7 years assuming a 3% surgical revision rate per year, a 3% decrease in sickness-related disability, and a 5% discount rate. The model was sensitive to changes in the total cost of operation, the surgical revision rate, and the anticipated disability benefit. We conclude that significant direct and indirect medical cost savings may be achieved after surgical intervention for chronic sinusitis and these savings eventually break even with the total cost of surgery itself.

    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

    Three cases are presented in which patients presented with either cutaneous swelling or cutaneous sinus tracts of odontogenic origin. A cutaneous sinus tract of odontogenic origin is a pathway through the alveolar bone that typically begins at the apex of an infected tooth or of an infected portion of the dental alveolus and empties infected material (pus) through the skin. Where as the more common finding of an oral fistula is a pathway from the apical periodontal area of a tooth to the surface of the oral mucous membrane, permitting the discharge of suppurative material. Diagnosis, etiology and treatment are discussed with reference to patient history, clinical examinations, imaging, and treatment perspectives. PMID:23662083

    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.

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

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

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

    5-Fluorouracil (5-FU) is a commonly used anti-neoplastic agent. 5-FU has been not uncommonly associated with cardiotoxicity, although the many potentially causative mechanisms are yet to be established. Here, we present the case of a 61-year-old gemstone miner who developed symptomatic sinus bradycardia while receiving a continuous 5-FU infusion combined with radiotherapy for locally advanced rectal cancer. This dysrhythmia is an unusual type of 5-FU toxicity, our case being the second described. We review the actions of 5-FU and the various proposed mechanisms of its cardiotoxic effects. PMID:21762335

    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.

  2. Origin of the sinus impulse.

    1996-03-01

    It was generally accepted that the site of normal impulse origin within the atria was a single static focus within the sinus node. This review will examine how this model of impulse origin came about and has evolved. Early on, conflicting data suggested that the sinus node focus was not static and changed with interventions that changed heart rate, such as vagal stimulation. Furthermore, even with removal of the sinus node, a normal atrial rhythm was generated. High-resolution mapping in humans and dogs showed that the initiation of the impulse was dynamic and could be multicentric, with more than one focus initiating a single beat. Shifts in the site of origin correlated with changes in rate and were consistent with P wave changes routinely observed in the standard ECG. These studies suggested multiple pacemakers were responsible for impulse initiation. However, it was not clear how these widespread pacemakers were coordinated to function synchronously. Recent canine data suggest that the node may be partially insulated from the surrounding atrium, resulting in multicentric origin starting from a single site within the node. What has evolved is a model of impulse origin with a sinus node having discrete exit sites and a dominant pacemaker within the node that can shift to other nodal sites. Complex and changing conduction out of the node, coupled with extranodal pacemakers, which can assume dominance over the node, combine with the autonomic nervous system to control heart rate and the pattern of impulse origin within the atria.

    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.

    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.

    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

    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 management of cavernous sinus and invasive parasellar meningiomas often requires a multimodality treatment approach. Early attempts at complete or near-complete removal of parasellar meningiomas involving the cavernous sinus, Meckel cave, clivus, and sella using anterolateral or lateral skull base approaches were typically unsuccessful and yielded high rates of new cranial neuropathy and other complications. This article presents a strategy of endonasal endoscopic parasellar skull base bony decompression and limited tumor removal followed by stereotactic radiotherapy, stereotactic radiosurgery, or observation. Patient selection, technical nuances, potential complications, and initial outcomes in a small series of patients are discussed. PMID:26141358

    The clinical course and pathologic features of a 72 year old female who presented with epistaxis are presented. Radiographic findings were notable for a large, soft tissue lesion filling the maxillary sinus with significant bony erosion and expansion. The patient was ultimately diagnosed with epithelioid hemangioendothelioma (EHE) and underwent endoscopic resection. She has no evidence of local, regional or distant recurrence 14 months post-surgery. The rarity of this neoplasm, the unusual anatomic location and non-specific symptoms present diagnostic and management challenges. Epithelioid vascular tumors encompass a spectrum of benign and malignant tumors. EHE itself is thought to have an intermediate malignant behavior pattern, though cases with indolent behavior have been reported. Differentiation of EHE from other lesions has historically based on histopathology. Additionally, recent studies have described a recurrent genetic fusion WWTR1-CAMTA1 in EHE, involving t(1;3) (p36;q25). This represents the second reported case of EHE arising in a paranasal sinus. The histopathologic findings of this lesion are reviewed. PMID:25963905

    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

    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.

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

    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).

    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.

    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: The inappropriate closure of the vocal cords is characteristic of vocal cord dysfunction (VCD). These patients present with wheezing and frequently receive a misdiagnosis of asthma. Objective: To demonstrate the ability of computed tomography (CT) scored for the presence and extent of sinus disease and markers of inflammation to distinguish patients with VCD from patients with asthma. Methods: Comparisons of 13 patients with VCD were made to 77 patients presenting to the emergency room with acute asthma, 31 non-acute asthmatic patients, and 65 nonasthmatic controls. Evaluation consisted of exhaled nitric oxide gas (eNO), circulating eosinophils, and total serum immunoglobulin (Ig)E, as well as the sinus CT scan. Results: Extensive sinus CT changes were present in 23 of 74 acute asthmatic patients, 5 of 29 non-acute asthmatic patients, and 2 of 59 nonasthmatic controls. In addition, absolute eosinophil counts, eNO, and total IgE were significantly elevated among the asthmatic patients. Sinus symptoms reported by questionnaire did not predict sinus CT findings. Among the patients with VCD, none had extensive sinus disease. They also had normal eNO, low IgE, and normal eosinophil count. Five of the patients presenting to the emergency room who were identified as acute asthmatic were identified with VCD by laryngoscopy and were all characterized by the absence of significant inflammation on their sinus CT scan, low IgE, and normal eosinophil count. Conclusions: Among patients presenting with intermittent or reversible airway obstruction, patients with VCD can be distinguished from asthma by minimum or absence of inflammation in their sinuses as shown by CT scan. Clinical symptom scores are not predictive of presence or extent of sinus disease in most cases. PMID:12669895

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

    Viper venom toxicities comprise mainly bleeding disorders and nephrotoxicity. Cardiotoxicity is a rare manifestation of viper bite. We describe the case of a previously healthy 35-year-old man who developed coagulopathy and sinus node dysfunction following a viper bite. Electrocardiography showed sinus arrest and junctional escape rhythm. This is the first account of sinus node dysfunction caused by a viper bite. PMID:24887872

    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

    Objectives/Hypothesis Chronic sinusitis is nearly universal in humans with cystic fibrosis (CF) and is accompanied by sinus hypoplasia (small sinuses). However, whether impaired sinus development is a primary feature of loss of the cystic fibrosis transmembrane conductance regulator (CFTR) or a secondary consequence of chronic infection remains unknown. Our objective was to study the early pathogenesis of sinus disease in CF. Study Design Animal/basic science research. Methods Sinus development was studied in a porcine CF model. Results Porcine sinus epithelia expressed CFTR and exhibited transepithelial anion transport. Disruption of the CFTR gene eliminated both. Sinuses of newborn CF pigs were not infected and showed no evidence of inflammation, yet were hypoplastic at birth. Older CF pigs spontaneously developed sinus disease similar to that seen in humans with CF. Conclusions These results define a role for CFTR in sinus development and suggest the potential of the CF pig as a genetic model of CF-sinus disease in which to test therapeutic strategies to minimize sinus-related CF morbidity.

    2004-04-01

    Odontogenic sinusitis is a well-recognized condition and accounts for approximately 10% to 12% of cases of maxillary sinusitis. An odontogenic source should be considered in patients with symptoms of maxillary sinusitis who give a history positive for odontogenic infection or dentoalveolar surgery or who are resistant to standard sinusitis therapy. Diagnosis usually requires a thorough dental and clinical evaluation with appropriate radiographs. Common causes of odontogenic sinusitis include dental abscesses and periodontal disease perforating the Schneidarian membrane, sinus perforations during tooth extraction, or irritation and secondary infection caused by intra-antral foreign bodies. The typical odontogenic infection is now considered to be a mixed aerobic-anaerobic infection, with the latter outnumbering the aerobic species involved. Most common organisms include anaerobic streptococci, Bacteroides, Proteus, and Coliform bacilli. Typical treatment of atraumatic odontogenic sinusitis is a 3- to 4- week trial of antibiotic therapy with adequate oral and sinus flora coverage. When indicated, surgical removal of the offending odontogenic foreign body (primary or delayed) or treatment of the odontogenic pathologic conditions combined with medical therapy is usually sufficient to cause resolution of symptoms. If an oroantral communication is suspected, prompt surgical management is recommended to reduce the likelihood of causing chronic sinus disease. PMID:15064067

    Catheter ablation for inappropriate sinus tachycardia (IST) is recommended for patients symptomatic for palpitations and refractory to other treatments. The current approach consists in sinus node modification (SNM), achieved by ablation of the cranial part of the sinus node to eliminate faster sinus rates while trying to preserve chronotropic competence. This approach has a limited efficacy, with a very modest long-term clinical success. To overcome this, proper patient selection is crucial and an epicardial approach should always be considered. This brief review will discuss the current role and limitations of catheter ablation in the management of patients with IST. PMID:26310299

  16. 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

Odontomas are also called benign growth abnormalities or hamartomas. They represent a more common type of odontogenic tumor and are related to various disorders such as bad dental placements, expansion, increased volumetric bone, and no eruption of permanent teeth. Usually they have an asymptomatic evolutionary course. The etiologic factors, although obscure, are related to local trauma, infection, and genetic factor. The structural composition of an odontoma consists of mature dental tissues. Odontomas can be differentiated according to their anatomical presentations: Compound odontoma-clusters of several denticles and complex odontoma-well defined tumefaction mass. The diagnosis can be performed by radiographic examination. PMID:26389051

    Venous sinus pathology can result in multiple pathological diseases, including idiopathic intracranial hypertension (IIH). There remains a paucity of information on anatomical luminal variations of the major venous sinuses which may contribute to the etiology of certain disease states. Thirty-six transverse and sigmoid sinuses were removed following dissection of 19 unfixed cadaveric heads. Sinuses were opened longitudinally to study luminal variations. A semiquantitative classification system was developed to assess septations and blind pouches. Seventy-nine percent of cadavers had a luminal anatomical variation. Forty-four percent and 42% of sinuses dissected had occurrence of a septations or blind pouches, respectively. Thirty percent of septations and 25% of pouches were classified as large. Incidence of anatomical variations was not statistically significant between cadaver gender or sinus laterality. Luminal variations are present in the transverse and sigmoid sinuses at rates higher than expected. This study is the first to report the presence of blind pouches in the luminal wall of transverse and sigmoid sinuses. These variations can have clinical importance to the endovascular surgeon and may also contribute to the pathophysiological etiology of venous sinus diseases.

    Carotid-cavernous sinus fistula is an arteriovenous fistula between the internal carotid artery and the cavernous sinus, and is usually caused by a traumatic tear or a ruptured aneurysm of the cavernous segment of the internal carotid artery. We describe a rare case of delayed intracranial haemorrhage and carotid-cavernous sinus fistula that presented 3 weeks after fracture of the facial bones. The patient developed orbital apex syndrome including ptosis of upper eyelid, pulsatile exophthalmos, chemosis, loss of ocular motility, monocular blindness on the right, and numbness of the right infraorbital region. After transcatheter intra-arterial embolisation, the ptosis and chemosis improved. PMID:23958350

    Allergic fungal sinusitis (AFS) has been recognized as an important cause of chronic sinusitis commonly caused by Aspergillus spp. and various dematiaceous fungi like Bipolaris, Alternaria, Curvalaria, and etc. Ulocladium botrytis is a non pathogenic environmental dematiaceous fungi, which has been recently described as a human pathogen. Ulocladium has never been associated with allergic fungal sinusitis but it was identified as an etiological agent of AFS in a 35 year old immunocompetent female patient presenting with chronic nasal obstruction of several months duration to our hospital. The patient underwent FESS and the excised polyps revealed Ulocladium as the causative fungal agent. PMID:22347556

    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. PMID:25636667

    Ossifying fibroma (OF) is a benign fibro-osseous lesion which was first described by Menzel in 1872. It is commonly seen in the head and neck regions and represents an aggressive pattern when the midface and paranasal sinuses are involved. We report a 36 years old white woman with OF in the right ethmoid sinus. Computed Tomography (CT) scan images showed a hyperdense mass. Transnasal endoscopic resection was performed and histopathological examination confirmed the diagnosis of OF. The present case is notable because involvement of the ethmoid sinus is rare in this condition with only 48 cases reported in the literature until June 2011. PMID:22091316

    The sinus lift technique, introduced in 1976 by Tatum and subsequently described by Boyne in 1980, is nowadays considered a safe and reliable procedure for the rehabilitation of the atrophic upper posterior maxilla. The alveolar antral artery (AAA) is anastomoses between the posterior superior alveolar artery (PSAA) and the infraorbital artery (IOA) and may be present in the sinusal antrostomy. The haemorrhage of this vascular bundle represents the second intra-operatory complication in term of frequency during sinus lift procedure. Purpose of this study was to illustrate and describe a new technique allowing the AAA isolation during sinus lift procedure in cases in which the artery is clearly present inside the surgical area, detectable through CT scan exam. Presence, course and possible identification of the alveolar antral artery are also discussed, according to the studies present in the literature. PMID:24949106

    We present a case of maxillary sinusitis caused by Schizophyllum commune, in a 50-year-old female. The patient presented with nasal obstruction, purulent nasal discharge from right side of the nose, cough, headache, and sneezing. Computed tomography revealed extensive opacity of the right maxillary sinus as well as erosion of the nasal wall and maxillary bone. Functional endoscopic sinus surgery was done, and fungal debris present on right side of the maxillary sinus was removed and sent to laboratory. Potassium hydroxide (KOH) examination of the nasal discharge showed hyaline, septate hyphae. Primary isolation on Sabouraud's dextrose agar (SDA) yielded a white woolly mould. Banana peel culture after 8 weeks showed macroscopically visible fan-shaped fruiting bodies. Lactophenol cotton blue (LPCB) mount of the same revealed hyaline septate hyphae, often with clamp connections. Identification was confirmed by the presence of clamp connections formed on the hyphae and by vegetative compatibility with known isolates. PMID:22567479

    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

    Lymphocyte proliferation, mobility and longevity make them prime targets for virus infection. Myeloid cells that process and present environmental antigens to lymphocytes are consequently an important line of defence. Subcapsular sinus macrophages (SSMs) filter the afferent lymph and communicate with B-cells. How they interact with B-cell-tropic viruses is unknown. We analysed their encounter with murid herpesvirus-4 (MuHV-4), an experimentally accessible gammaherpesvirus related to Kaposi's sarcoma-associated herpesvirus. MuHV-4 disseminated via lymph nodes, and intranasally or subcutaneously inoculated virions readily infected SSMs. However, this infection was poorly productive. SSM depletion with clodronate-loaded liposomes or with diphtheria toxin in CD169–diphtheria toxin receptor transgenic mice increased B-cell infection and hastened virus spread to the spleen. Dendritic cells provided the main route to B-cells, and SSMs slowed host colonization, apparently by absorbing virions non-productively from the afferent lymph. PMID:25872742

    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

    Background: Perioperative straight sinus thrombosis is extremely rare. Case Description: A 59-year-old female was admitted to our department because of incidentally found small anterior cerebral artery (A1) aneurysm with microbleeding. After clipping the cerebral aneurysm, she had delayed emergence from anesthesia, total aphasia, and right hemiparesis. Fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) of the head showed hyperintensity in the bilateral caudate nuclei, putamina, and thalami, and computed tomography of the head showed a hyperdense straight sinus, suggesting straight sinus thrombosis. Her neurologic symptoms improved gradually, and she achieved a full clinical recovery, with radiological evidence of recanalization of the straight sinus at follow-up. Conclusion: The possibility of straight sinus thrombosis should be considered in postoperative patients with unexplained postoperative deficits when MRI demonstrates hyperintensity in the bilateral basal ganglia and thalami on FLAIR signal images.

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

    The present report describes a minimally invasive technique for transcrestal sinus floor elevation, namely the Smart Lift technique, which is based on the controlled use of drills and osteotomes. The rationale of this technique is to provide predictable vertical bone augmentation into the sinus cavity by (1) using the existing residual bone as a viable graft and (2) limiting the incidence of membrane perforation and postsurgery morbidity. Surgical steps of the procedure are thoroughly illustrated by means of a paradigmatic case. The Smart Lift procedure was compatible with sinus floor elevation and implant stability for up to 1 year following surgery. No complications occurred during or after surgery. On periapical radiographs, a radiopaque area corresponding to the augmented sinus floor was present above the apical portion of the implant. PMID:20376370

    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 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

    Lactobacillus acidophilus rarely causes bacterial endocarditis, because it usually resides in the mucosa of the vagina, gastrointestinal tract, and oropharynx. Moreover, sinus of Valsalva aneurysms are rare cardiac anomalies, either acquired or congenital. We present the case of a middle-aged man whose bacterial endocarditis, caused by Lactobacillus acidophilus, led to an aneurysmal rupture of the sinus of Valsalva into the right ventricular outflow tract. The patient underwent successful surgical repair, despite numerous complications and sequelae. PMID:27127435

    This is a case report of a Pott's puffy tumor, characterized by a subperiosteal abscess associated with frontal bone osteomyelitis, as a consequence of a frontal sinusitis, in a 15-year-old boy. Pott's puffy tumor is a rare condition usually seen as a complication of frontal sinusitis and more commonly described in children. Given that, superficial temporal artery pseudoaneurysms might be interpreted as a cyst or lipoma, it is imperative that physicians be aware of their presentation. PMID:20653869

    Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS) is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH) improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females) meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS. PMID:27186561

    Paranasal sinus mucocele is a benign pseudocystic lesion, which may originate from any of the sinus cavities. Although the diagnosis may be suggested by the clinical presentation, CT is necessary to accurately analyze the regional anatomy and extent of the lesion. MRI is helpful in defining the limited unusual lesions occurring in critical areas. Standard treatment is surgical marsupialization, through endonasal sinus surgery, which offers a conservative, minimally invasive approach, and respects the sinus architecture and natural drainage. Our long-term experience with the endonasal endoscopic approach for the treatment of mucoceles led us to subsequently expand our indications to include most mucoceles, either as the sole approach or associated with an external approach. Comprising the surgical experience of two collaborating universities, this paper describes the indications for the endonasal surgical approach and the long-term postoperative followup. PMID:15243570

    Cerebral venous sinus thrombosis is a rare type of stroke primarily affecting young women. Diagnosis is generally delayed or overlooked due to a wide spectrum of clinical symptoms. Subdural hematoma secondary to cerebral venous sinus thrombosis is very rare. We report a case of 40-year-old female with cerebral venous sinus thrombosis who presented to us with an acute subdural hematoma and subarachnoid hemorrhage besides venous infarct. Management of such patients is complicated due to the rarity of the condition and contraindication for the use of anticoagulation. We conducted a thorough literature search through PubMed and could find only nine cases of spontaneous subdural hematoma secondary to cerebral venous sinus thrombosis. PMID:27057237

    The authors make short review on the one of most malignant neoplasms in human pathology--its incidence, ethiology, pathogenesis, clinical characteristics, diagnosis, treatment and prognostic features. We present a clinical case from our practice--a melanoma of the nasal cavity and paranasal sinuses--a rare localization. Melanocarcinomas of the mucous membranes of the nasal cavity and paranasal sinuses are almost uniformly fatal. Undoubtedly some of the contributory reasons for their grave prognosis are the delay in detection and in accurate histologic diagnosis, the frequent injudicious therapy, the difficulties in adequate operative removal. Melanomas o mucous membranes may arise in mucosa lined by either normally present, or metaplastic stratified squamous epithelium. PMID:12024680

    Endodermal sinus tumors are rare malignant germ cell tumors that usually originate from the gonads and are rarely observed extragonadally. Pure primary endodermal sinus tumors of the cerebellar hemisphere are extremely rare and patients diagnosed with the disease often have a poor prognosis. The symptoms of YSTs are unspecific and associated with the location of tumors. Intracranial YSTs (such as cerebellar hemispheres) always present with symptoms including headache and poor vision. The present study reports the case of a three-year-old male who presented to The First Affiliated Hospital of Nanchang University (Nanchang, China) with a headache that had persisted for one month, and then worsened for the last 10 days. This was accompanied by vomiting and gait disturbance. An abnormal signal mass was identified in the left cerebellar hemisphere on brain magnetic resonance imaging. The case initially presented as a medulloblastoma and the patient was followed up for six months. The final pathology report revealed an endodermal sinus tumor, also known as a yolk sac tumor. Six months following resection of the left cerebellar tumor, the patient succumbed to recurrence of the disease, due to acute vomiting and severe headache. PMID:25202397

Principles of management are discussed and the techniques for the operative procedures described. While rare in occurrence in children, it is felt that traumatic involvement of the nasal-frontal ducts or posterior tables of the frontal sinus requires an osteoplastic flap--fat obliteration of the frontal sinus cavity in order to preclude subsequent mucocele development or mucosal ingrowth into the anterior fossa.

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

  13. Examination and Intervention for Sinus Tarsi Syndrome

    PubMed Central

    2009-01-01

    Athletes with persistent anterolateral ankle discomfort may have developed sinus tarsi syndrome (STS). Sinus tarsi syndrome develops from excessive motions of the subtalar joint that results in subtalar joint synovitis and infiltration of fibrotic tissue into the sinus tarsi space. Physical therapists treating athletes with ankle conditions should examine the talocrural and subtalar joints for signs of hypermobility as injuries can affect both of these important articulations of the lower extremity. Localized ankle discomfort to the sinus tarsi space and feelings of instability with pronation and supination movements of the subtalar joint will help identify STS. Intervention for this condition will focus on enhancing subtalar joint stability and function of the lower extremities. The purpose of this clinical commentary is to discuss the etiologies and signs of STS and describe the components of an intervention plan appropriate for athletes with STS. PMID:21509118

    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. PMID:25675268

    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. PMID:1290922

    Olfactory neuroblastoma (ONB) is a rare malignant tumor. Although the vast majority of cases arise in the nasal cavity, ONB is rarely reported in ectopic locations. We report a case of ONB in the maxillary sinus. A 63-year-old woman presented with left-sided nasal obstruction and epistaxis. Magnetic resonance imaging showed a nonenhancing left maxillary sinus tumor. Histologic sections showed ONB, Hyams grade IV, invading bone, skeletal muscle, and adjacent fibroadipose tissue. It is essential to be accurate when diagnosing sinonasal tumors because the differential diagnosis is broad, and one must consider the possibility of ectopic ONB, although it is rare. The behavior of ONB and other neuroendocrine tumors of the sinonasal region is quite different, and there are varied approaches to treatment. Therefore, an accurate diagnosis as well as correct grade and stage must be assigned. PMID:27180059

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

    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

Multiple treatment options and algorithms have been proposed by multiple specialties throughout the years; however, the optimal method of frontal sinus repair has yet to be discovered. Overwhelming complications such as meningitis, encephalitis or brain abscess are quite uncommon nowadays. Nevertheless, late development of invasive mucoceles is not a rarity and therefore long-term follow-up is mandatory. PMID:24790677

    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.

    The presence of frontal cells poses unique challenges when using endoscopic approaches. This study describes the use of a balloon dilation system as an aid for functional endoscopic sinus surgery (FESS) to access the frontal sinus in cases that would traditionally require open approaches. We present a case series of four patients with chronic rhinosinusitis refractive to medical management who underwent FESS with the aid of a balloon dilation system at a tertiary referral center. All patients had variant forms of frontal sinus anatomy. Surgical techniques will be described and use of the balloon system will be reviewed. All patients (aged 13–68 years) successfully underwent fontal sinusotomies with the assistance of a balloon dilation system, which was used in a variety of ways: to dilate the narrow infundibulum of a high intersinus septal cell, to remove an anteriorly located type III frontal sinus cell, to expand the natural frontal ostium in the presence of excessive agger nasi pneumatization, and to remove a type IV frontal sinus cell. All patients were spared an osteoplastic flap or trephination, and there were no intraoperative complications. No postoperative bleeding, infection, or cerebral spinal fluid leaks were reported. Balloon dilation in combination with standard frontal sinus dissection techniques may be beneficial for a select group of patients with complex frontal anatomy. In this series of patients, the balloon dilation system was used as a tool during FESS and eliminated the need for open approaches. PMID:25565046

    In this study, bovine hydroxyapatite (HA) alone or in combination with activated platelet-rich plasma (PRP) was examined for its usefulness for single-stage sinus grafting in minipigs. In 12 adult minipigs, Schneider's membrane of 24 sinuses was elevated bilaterally through an extra-oral approach. The material was divided into two groups of 12 sinuses. In one of these groups, the space between Schneider's membrane and the sinus wall was grafted with activated autogenous PRP and HA (PRP side). In the other, HA alone was used for grafting (control side). At the same time two dental implants with a machined surface were inserted into the grafting material through the facial sinus wall. Four animals of each group were sacrificed at 3, 6 and 12 weeks, and undecalcified thin-cut and ground sections (Donath 1988) stained with toluidine blue were prepared. In the facial sinus wall, fewer bone-to-implant contacts were present on the PRP side at 3 and 6 weeks than on the control side. At 12 weeks, the PRP side had caught up with the control side. In grafted bone, contacts on the PRP side were more extensive than on the control side at 3 weeks, had dropped below control side levels at 6 weeks and surpassed these at 12 weeks. This study showed that PRP has a differential effect on osseointegration in grafted bone and local host bone. Combined with HA it was not demonstrably superior to HA alone. PMID:12869013

A 17-year-old boy presented with nape pain a day after a head blow during a gymnastics competition (backward double somersault). On admission, he showed no neurological deficit. CT scans revealed no skull fractures, and there were no abnormalities in the brain parenchyma. However, his headache worsened day-by-day and he had begun to vomit. Lumbar puncture was performed on Day 6, and the opening pressure was 40 cm of water. After tapping 20 mL, he felt better and the headache diminished for a few hours. MR venography performed on Day 8 revealed severe flow disturbance in the posterior third of the superior sagittal sinus with multiple venous collaterals. Because of the beneficial effects of lumbar puncture, we decided to manage his symptoms of intracranial hypertension conservatively with repeated lumbar puncture and administration of glycerol. After 7 days of conservative treatment, his symptoms resolved completely, and he was discharged from the hospital. Follow-up MR venography performed on Day 55 showed complete recanalization of the superior sagittal sinus. The exact mechanism of sinus thrombosis in this case is not clear, but we speculate that endothelial damage caused by shearing stress because of strong rotational acceleration or direct impact to the superior sagittal sinus wall may have initiated thrombus formation.

    The sigmoid sinus diverticulum (SSD) is an increasingly recognized cause of pulsatile tinnitus (PT). Surgical reconstruction of the sigmoid sinus wall has been found to be highly effective for SSD; however, surgical techniques still need to be refined to reduce the incidence of serious postoperative complications. Moreover, scrutinizing more cases of SSD is desirable for establishing the diagnostic criteria and standardizing the surgical technique. This study was retrospectively undertaken in 28 patients who were diagnosed with SSD upon computed tomography angiography (CTA) and digital subtraction angiography findings at Beijing Tongren Hospital in China. A majority of patients (20/28) presented with SSD and accompanying sigmoid sinus wall dehiscence (SSWD). Twenty-five patients opted to undergo sigmoid sinus wall reconstruction, and 3 patients refused surgery. Following surgery, 17 patients experienced complete resolution of PT, 3 patients experienced partial resolution, and 5 patients experienced no change in PT. No serious complications were found postoperatively. A comparative analysis of the preoperative and postoperative CTA findings suggested that completely resolving SSD and the accompanying SSWD resulted in the elimination of PT. In conclusion, SSD is generally accompanied by SSWD. Sigmoid sinus wall reconstruction is a safe and effective approach for the treatment of SSD. During surgery, completely resolving both SSD and SSWD is advisable, and maintaining the normal diameter of the sigmoid sinus is imperative. PMID:26020395

  9. Experience with a new micro-applicator for laser surgery of recurrent polypous sinusitis

    Laser surgical methods as an alternative to conventional surgery for the treatment of recurrent chronic polypous sinusitis have been widely established over the past few years. While feedback-controlled contact laser application causes little disruption to the tissue, the minimal-invasive approach is limited by the accessibility of recurrent polyps. We employ a semi-rigid applicator for the guidance of the laser fiber with an outer diameter of 4 mm, whose tip can be adjusted and fixed in a flexible manner before or while accessing the operative field. In addition to the laser fiber channel, two further integrated channels can be used for laser plume suction and for introducing a flexible micro-endoscope with an outer diameter of 1.3 mm. This new device enables the surgeon to apply laser energy in close proximity to an endoscope and smoke suction channel even in regions with limited accessibility, such as the maxillary sinus bottom or the frontal sinus recess. The single-handed use facilitates maneuvering this device in narrow endonasal cavities. The integrated micro-applicator presented here widens the scope of operative options for endonasal laser surgery. In addition to a better access to all regions of the paranasal sinuses following conventional endonasal sinus surgery, its use for treating locally limited chronic polypous sinusitis via natural drainage pathways as a primary surgical procedure bears considerable potential for further evaluation.

    The coronary sinus and its tributaries were studied by anatomical dissection in 37 adult human cadaveric hearts, which had been fixed in formalin solution. An anastomosis of approximately 1.0 mm in calibre was observed between the anterior and posterior interventricular veins in 19% of specimens. Myocardial bridges were detected above the anterior interventricular vein or its tributaries in 8% of specimens. The great cardiac vein formed the base of the arteriovenous trigone of Brocq and Mouchet with the bifurcating branches of the left coronary artery in 89% of specimens and formed an angle accompanying these arterial branches in 11%. In the trigone the anterior interventricular and great cardiac veins were superficial to the arteries in 73% of specimens. The left marginal vein was present in 97% of specimens, emptying into the great cardiac vein in 81% of cases and into the coronary sinus in the remaining 19%. The small cardiac vein was present in 54% of specimens. In the coronary sulcus the great cardiac vein was adjacent to the circumflex branch of the left coronary artery in 76% of specimens and to the right coronary artery in 5%: in 19% there was no relationship with either artery. The coronary sinus maintained a relationship with the right coronary artery in 46% of specimens and with the left coronary artery in 32%: in 22% it had no relationship with these vessels.

    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%.

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

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

    An inflammatory myofibroblastic tumor (IMT) is an immunohistochemically diverse entity demonstrating neoplastic and nonneoplastic qualities. Although IMTs can arise in any area of the body, lesions arising in certain sites, namely, the nasal cavity, paranasal sinuses, and pterygopalatine fossa, demonstrate a heightened neoplastic and invasive potential. Despite case specific complete tumor regression and disease remission in response to pharmacotherapeutics, a subset of IMTs remain resistant to all forms of therapy. We present such a case, a 34-year-old female patient, with a highly resistant, maxillary sinus IMT. Her refractory, ALK-1 negative IMT has not responded well to novel therapies reported in current literature. This case suggests the role of zonal expressivity within a single lesion as a probable mechanism for its highly resistant nature and should promote determination of each IMT's cytogenetic profile to provide more effective targeted therapy. Paper includes a literature review of all maxillary sinus IMTs from 1985 to 2014 along with their immunohistochemical staining, treatments, and outcomes. PMID:25763286

    Physicochemical characteristics of a biomaterial directly influence its biological behavior and fate. However, anatomical and physiological particularities of the recipient site also seem to contribute with this process. The present study aimed to evaluate bone healing of maxillary sinus augmentation using a novel bioactive glass ceramic in comparison with a bovine hydroxyapatite. Bilateral sinus augmentation was performed in adult male rabbits, divided into 4 groups according to the biomaterial used: BO-particulate bovine HA Bio-Oss(®) (BO), BO+G-particulate bovine HA + particulate autogenous bone graft (G), BS-particulate glass ceramic (180-212 μm) Biosilicate(®) (BS), and BS+G-particulate glass ceramic + G. After 45 and 90 days, animals were euthanized and the specimens prepared to be analyzed under light and polarized microscopy, immunohistochemistry, scanning electron microscopy (SEM), and micro-computed tomography (μCT). Results revealed different degradation pattern between both biomaterials, despite the association with bone graft. BS caused a more intense chronic inflammation with foreign body reaction, which led to a difficulty in bone formation. Besides this evidence, SEM and μCT confirmed direct contact between newly formed bone and biomaterial, along with osteopontin and osteocalcin immunolabeling. Bone matrix mineralization was late in BS group but became similar to BO at day 90. These results clearly indicate that further studies about Biosilicate(®) are necessary to identify the factors that resulted in an unfavorable healing response when used in maxillary sinus augmentation.

    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.

    On the examination of 200 embryonal petrous bones the factors affecting the morphology of the tympanic sinus under physiological conditions are discussed. The development of the tympanic sinus begins during the fourth month of embryonic life. In an embryo of 5 months the floor of the tympanic sinus developing between the cochlea and the vestibulum consists of lamellae resembling a wicker basket. Caudally, its floor reaches at first the lower part of the tympanum, for at this stage the styloid prominence and the pavimentum pyramidis are not yet fully developed. In the eighth and ninth month of foetal life the tympanic sinus is narrowed by the styloid prominence, from the floor and from the cranial side it is bordered by the fully developed ponticulus medialis. In postnatal life the development of the membranous bony substance of the promontory, subiculum promontorii and styloid prominence, each narrows the tympanic sinus in some degree. Under the influence of vascular factors highly developed trabeculae and lamellae are formed in them. The cavity is deeper in the dolichocephalics and is more shallow in brachycephalics. PMID:1168885

    Cystic fibrosis (CF) pigs spontaneously develop sinus and lung disease resembling human CF. The CF pig presents a unique opportunity to use gene transfer to test hypotheses to further understand the pathogenesis of CF sinus disease. In this study, we investigated the ion transport defect in the CF sinus and found that CF porcine sinus epithelia lack cyclic AMP (cAMP)-stimulated anion transport. We asked whether we could restore CF transmembrane conductance regulator gene (CFTR) current in the porcine CF sinus epithelia by gene transfer. We quantified CFTR transduction using an adenovirus expressing CFTR and green fluorescent protein (GFP). We found that as little as 7% of transduced cells restored 6% of CFTR current with 17-28% of transduced cells increasing CFTR current to 50% of non-CF levels. We also found that we could overcorrect cAMP-mediated current in non-CF epithelia. Our findings indicate that CF porcine sinus epithelia lack anion transport, and a relatively small number of cells expressing CFTR are required to rescue the ion transport phenotype. These studies support the use of the CF pig as a preclinical model for future gene therapy trials in CF sinusitis. PMID:23511247

    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.

    A compromised overview of surgical techniques regarding the nose (functional) and para nasal sinus inflammation surgical treatment is exposed in this article. The nasal septum is within the focus for function, form and stability for the nasal structure (especially for tip and back of the nose) and for success of a rhinoplasty. An important role play the lower nasal turbinates regulating nasal air flow and thus having a great effect after turbinate surgery (submucosal resection and lateral fracturing).The endonasal endoscopy is of utmost importance for diagnosis, therapy and detection of recurrence. In severe cases of nasal polyps, functional endoscopic sinus surgery (FESS) remains the ultimate therapy. However, the indication to operate will be carried out after exhaustion of medical treatment. The most important recurrent prophylaxis for rhino sinusitis and nasal polyps is an appropriate post operative nasal care. PMID:26756658

    Background: Saline irrigations are proving to be a valuable intervention in the treatment of chronic sinusitis. The use of surfactants is a well established additive to topical treatments known to reduce surface tension and may prove to be a simple, nonoperative intervention to improve intrasinus douching penetration. Methods: Six 30-mL, flat-bottomed medicine cups with circular holes cut through the bottom center and varying in diameter from 1 to 6 mm were created with punch biopsies. Water, saline, saline/dye, and saline/dye/surfactant were compared for maximum holding pressure via these modeled ostia. Holding pressures also were determined for cups with septal mucosa fused to the bottom with holes ranging from 1 to 6 mm. In addition, analysis was carried out with blood and blood/surfactant. Finally, five thawed, fresh-frozen cadaver heads were evaluated before any sinus surgery with water/dye and water/dye/surfactant for intrasinus penetration. Results: Surfactant significantly improved the ability of all solutions to penetrate ostia in both the plastic cup and fused septal mucosa model. All nonsurfactant-containing solutions were not statistically different from one another, nor did surfactant change the ostial penetration of blood. Surfactant significantly improved the ability of sinus irrigant to penetrate unoperated sinus cavities (3.12 vs 3.5, p = .021). Conclusions: The addition of surfactant to saline irrigation improves ostial penetration in undissected and undiseased cadavers. This has practical implications for unoperated patients seeking care for sinus-related symptoms in that we have now described a method for improving topical treatment of target sinus mucosa prior to surgical intervention.

    2014-07-01

    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.

    The sinoatrial node, or sinus node, of humans is the principal pacemaker of the heart. Over the last century, studies have unraveled the complex molecular architecture of the sinus node and the expression of unique ion channels within its specialized myocytes. Aim of this review is to describe the embriology, the anatomy, the histology and the electrophisiology of the sinus node. PMID:27142063

    Thrombosis of the sinuses is a distinct cerebrovascular disorder that, unlike arterial stroke, most often affects young adults and children. The symptoms and clinical course are highly variable. During the past decade, increased awareness of the diagnosis, improved neuro-imaging techniques, and more effective treatment have improved the prognosis. More than 80% of all patients now have a good neurologic outcome. This review summarizes recent insights into the pathogenesis of sinus thrombosis, risk factors, and clinical and radiological diagnosis and discusses the current evidence and controversies about the best treatment.

    Sinus infection remains a common cause of orbital inflammatory disease, and prompt diagnosis is essential. A team approach early in the course of the disease, with an otolaryngologist serving as coordinator, is recommended. If vigorous medical therapy fails, abscess formation should be suspected and surgical drainage instituted without delay. Of 24 patients hospitalized with complications of sinusitis, 13 were found to have acute inflammatory disease and 11 had mucocele formation. Mortality in patients with acute inflammatory was 30%; in those with intracranial extension of infection it was 67%. PMID:628655

  17. Epidemiology and definition of inappropriate sinus tachycardia.

    PubMed

    Pellegrini, Cara N; Scheinman, Melvin M

    2016-06-01

    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

    2011-01-01

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

    2013-01-01

    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

    We describe the case of a previously healthy young man who presented with headache, diplopia, nausea, vomiting, and bilateral papilledema. Magnetic resonance venography of the brain revealed thrombosis of the right transverse sinus. Blood tests showed elevated homocysteine levels, and coagulation studies revealed a homozygous C677T mutation and a heterozygous A1298C mutation of the methylenetetrahydrofolate reductase (MTHFR) gene. The patient had no other etiology for venous thrombosis. We recommend screening patients who present with sinus thrombosis for MTHFR gene mutations. PMID:18666857

    Cardiac events associated with congenital coronary abnormalities are rare but potentially life-threatening in a young population. Most of these patients are not diagnosed before their initial cardiac event. Amongst such coronary artery anomalies, sudden death is frequently seen in an anomalous origination of a coronary artery from the opposite sinus. We herein present the case of a patient who presented with sudden cardiac arrest associated with an anomalous right coronary artery originating from the left sinus of Valsalva. Surgical treatment was selected because there was evidence of reversible ischemia based on the findings of a stress test. PMID:26726086

    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

    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.

    2015-01-01

    Background. The coronary venous system is an increasingly frequent target of minimally invasive cardiac procedures. The purpose of this paper is to assess the anatomical barriers in the right atrium to coronary sinus cannulation. Methods. We examined the anatomy of the right atrium, coronary sinus ostium, inferior and superior vena cava ostia in 110 randomly selected autopsied human hearts of both sexes (27% females; mean age 49.2 ± 17.5 years). Results. The Eustachian valve was present in 79 cases (71.8%) with mean height =4.9 ± 2.6 mm. The valve was perforated in 11 cases (13.9%). It is typically too small to hinder the coronary sinus catheterization, but in some cases (about 2%) a significantly protruding valve may be an obstacle. Chiari’s network (4.6%) is not a barrier to catheter entry into the right atrium but may significantly impede further catheter manipulations inside the heart venous system. A typical Thebesian valve leaves enough space for the passage of the standard catheter to the coronary sinus. Discussion. Detailed anatomy of various anatomical structures within the right atrium that could play a potential role in coronary sinus cannulation is discussed. PMID:26823994

    2016-01-01

    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

    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

    Background: Metronomic chemotherapy consisting of methotrexate and celecoxib recently has shown promising results in multiple studies in head and neck cancers. However, these studies have not included patients with maxillary sinus primaries. Hence, the role of palliative metronomic chemotherapy in patients with maxillary sinus carcinoma that is not amenable to radical therapy is unknown. Methods: This was a retrospective analysis of carcinoma maxillary sinus patients who received palliative metronomic chemotherapy between August 2011 and August 2014. The demographic details, symptomatology, previous treatment details, indication for palliative chemotherapy, response to therapy, and overall survival (OS) details were extracted. SPSS version 16 was used for analysis. Descriptive statistics have been performed. Survival analysis was done by Kaplan–Meier method. Results: Five patients had received metronomic chemotherapy. The median age was 60 years (range 37–64 years). The proportion of patients surviving at 6 months, 12 months, and 18 months were 40%, 40%, and 20%, respectively. The estimated median OS was 126 days (95% confidence interval 0–299.9 days). The estimated median survival in patients with an event-free period after the last therapy of <6 months was 45 days, whereas it was 409 days in patients with an event-free period postlast therapy above 6 months (P = 0.063). Conclusion: Metronomic chemotherapy in carcinoma maxillary sinus holds promise. It has activity similar to that seen in head and neck cancers and needs to be evaluated further in a larger cohort of patients.

  10. Stent hypersensitivity and infection in sinus cavities

    2013-01-01

    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

  15. Traumatic globe dislocation into the paranasal sinuses: Literature review and treatment guidelines.

    PubMed

    Amaral, Marcio Bruno Figueiredo; Nery, André Cardoso

    2016-05-01

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

    2012-01-01

    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

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

    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

    Tachycardia induced cardiomyopathy is a potentially lethal cause of heart failure generally because of atrial tachycardia and less frequently ventricular tachycardia. We present two cases of Marines with severe traumatic blast injuries secondary to improvised explosive device attacks whose hospital courses included amputation, massive blood transfusions, and multiple surgeries. Both patients had prolonged sinus tachycardia averaging >110 beats per minute and developed depressed left ventricular function, which recovered when treated with β blockers. Sinus tachycardia is often considered a physiological response to stress, and the purpose of this manuscript is to describe the cardiac injury apparently related to a prolonged stress response. In addition, the literature does not clearly recommend controlling heart rates in trauma patients with persistent sinus tachycardia, but it is a therapeutic option that should be considered by providers.

    Two cases of pneumosinus dilatans of the frontal sinus with cosmetic deformation are reported. In both cases one big hole without any interfrontal septum has been found. In the first case no efferent ducts of the frontal sinus have been visible, the second one showed only one. Surgical treatment by incision from ear to ear, and forming of a scalp flap with opening of the frontal sinus in the upper margin of the bony bulging. This bulging was left pedicled on the periosteum and fractured in many pieces. Forming of an artificial efferent duct to the nose by an incision below the left eyebrow. Good cosmetic results in both cases. X-rays fotos, pictures of the operation and postoperative results are demonstrated. Examinations of the human growth hormones (HGH) of the 24-years-old German and the 28-years-old Turkish man presented normal values. The author believes in a dysregulation of the efferent ducts.

    This is a case of an 11-year-old male with an ethmoid sinus mucocele who presented to our emergency department with an orbital mass. This mucocele was most likely related to an ipsilateral orbital subperiosteal abscess that required endoscopic drainage 9 years ago. Mucoceles are mucus-filled, epithelial-lined sacs that slowly develop in the paranasal sinuses when sinus drainage is obstructed by inflammatory processes, trauma, or prior surgery. They are rare in children and should be suspected in patients with progressive headache or orbital complaints. PMID:19092564

    We describe the delayed occurrence of a frontal sinus mucocele 14 years after the original trauma. The patient presented with a laterally displaced, enlarging mass that encroached on the dura. The sterile mucocele was removed, and the cranial defect was reconstructed with methyl methacrylate and wire mesh. Our experience confirms the known but rarely observed late development of a mucocele after pediatric facial trauma. To prevent the sequela of mucocele development, the mucosa of the rudimentary frontal sinus in the pediatric patient must be carefully sought and ablated during reconstructive procedures of the forehead when traumatic injury significantly disrupts the normal bony anatomy.

    Sinus elevation surgery has been used by the dental profession to increase bone quantity in the posterior maxilla for the placement of root-form implants. The original treatment protocol was developed using existing bone-healing theories that relied on expert opinion. In 2003 and 2004, 2 evidence-based literature reviews were published, expanding significantly on the previous review of 1996. The new reviews were based on the best studies available and were designed to present information that would help clinicians achieve more favorable outcomes. This article discusses this information and answers further questions relating to the sinus elevation procedure. PMID:17191648

    Frontal sinus mucoceles may present many years after traumatic injuries or surgical procedures involving the frontal bone, but have been rarely reported after fronto-orbital advancement. We describe a case of frontal sinus mucocele development in a 43-year-old patient with Apert syndrome who underwent fronto-orbital advancement as a child. This was treated with resection and free fibula osteomuscular flap reconstruction. Computer-aided design and manufacturing techniques were used to virtually plan the procedure and guide the osteotomies intraoperatively. Follow-up at 1 year postoperatively revealed no evidence of recurrence. PMID:23348310

    Epistaxis is a frequent health problem and the most common cause of emergency in otorhinolaryngology practice. In this report, a case of a 26-year-old patient with intractable epistaxis after endoscopic sinus surgery was presented. The epistaxis began at the fourth postoperative day and was unresponsive to endoscopic cauterization and anterior and posterior nasal packing. On angiographic investigation, a pseudoaneurysm of the sphenopalatine artery was detected and treated with microcatheter embolization. This is the second case of postoperative sphenopalatine pseudoaneurysm as a complication of endoscopic sinus surgery in the literature. PMID:24621700

    Subcutaneous involvement frequently occurs in maxillary sinus carcinoma. Radical resection does not include removal of the skin at risk. In standard postoperative wedge-pair treatment plans, the surface dose is dependent upon beam weighting, beam energy, and patient contour. Thermoluminescent dosimetry (TLD) measurements were performed to evaluate the surface dose of patients undergoing postoperative irradiation of maxillary sinus carcinoma following primary resection. When 60 Gy was delivered to isocenter with a 45 degrees wedge pair and 6 MV photons with 1 cm bolus, the subcutaneous tissues at risk received {approximately} 30 Gy. Based upon presented TLD measurements, supplemental electron beam therapy to the subcutaneous tissues if primarily involved should be considered.

    A 32-years-old man with a past history of hemorrhoids presenting with hemiparesis was diagnosed as having sagittal sinus thrombosis with hemorrtagic infarction. Laboratory data revealed macrocytic anemia (Hb 11.2 g/d/) with hypoproteinernia (5.5 g/d). After discharge the patient developed abdominal pain, diarrhea, edema in the leg and sustained anemia. Final diagnosis through colon fiberscope findings was Crohn's disease Macrocytic anemia seemed to be induced by Vit. B12 deficiency due to malabsorption. The mechanism and causal relationship between Crohn's disease and sinus thrombosis is discussed. PMID:17564049

    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

    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 Epidural anesthesia is one of the best options for lower abdominal and lower limb surgery. However, there have been insufficient reports regarding the use of epidural anesthesia for pilonidal sinus surgery. The present study was performed to compare the clinical profiles of epidural block performed with 0.75% levobupivacaine and 0.75% ropivacaine in this procedure. Methods Thirty patients undergoing pilonidal sinus surgery were randomly allocated into two groups: one group received levobupivacaine and the other received ropivacaine at 0.75% in a volume of 10 ml. Arterial blood pressure, heart rate, oxygen saturation, the onset time of analgesia and duration of block, highest sensory block level, perioperative and postoperative side effects, and patients' and surgeons' satisfaction were recorded. Results Hemodynamic stability was maintained in both groups throughout surgery. The onset time of analgesia (the time from epidural injection of local anesthetic to reach L2 sensorial block) was 6.26 ± 3.49 min in the levobupivacaine group and 4.06 ± 1.75 min in the ropivacaine group (P = 0.116). The duration of sensorial block (time for regression of sensory block to L2) was 297.73 ± 70.94 min in group L and 332.40 ± 102.22 min in group R (P = 0.110). Motor block was not seen in any of the patients in the study groups. Patients' and surgeons' satisfaction with the anesthetic technique were mostly excellent in both groups. Conclusions In patients undergoing pilonidal sinus surgery, both levobupivacaine and ropivacaine produce rapid and excellent epidural block without leading to motor block or significant side effects. Although not statistically significant, the onset time of anesthesia was shorter and the duration of effect was longer with ropivacaine than with levobupivacaine in this study. PMID:25844132

    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. PMID:27333013

    Asymptomatic rupture of a sinus of Valsalva aneurysm is rare. A fistula following rupture of a sinus of Valsalva aneurysm may cause infective endocarditis. Here, we report a case of infective endocarditis of an aorto-right atrial fistula caused by asymptomatic rupture of a sinus of Valsalva aneurysm. A 45-year-old male, who was first diagnosed with a heart murmur at the age of 37 years, presented with fever. Blood culture was positive for Streptococcus gordonii. Ultrasound echocardiography revealed an aorto-right atrial fistula caused by rupture of a sinus of Valsalva aneurysm. After the infective endocarditis was healed by antibiotics, we successfully performed surgical repair of the aorto-right atrial fistula. Although asymptomatic rupture of a sinus of Valsalva aneurysm is uncommon, it should be recognized as a possible cause of infective endocarditis. PMID:27180251

    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 frontal sinus is a sturdy part of the skull that is likely to be retrieved for forensic investigations. We evaluated frontal sinus parameters in paranasal sinus computed tomography (CT) images for sex determination. The study was conducted on 200 normal paranasal sinus CT images of 100 men and 100 women of Persian origin. We categorized the studied population into three age groups of 20-34, 35-49 and ⩾ 50 years. The number of partial septa in the right frontal sinus and the maximum height and width were significantly different between the two sexes. The highest precision for sex determination was for the maximum height of the left frontal sinus (61.3%). In the 20-34 years age-group, height and width of the frontal sinus were significantly different between the two sexes and the height of the left sinus had the highest precision (60.8%). In the 35-49 years age-group, right anterior-posterior diameter had a sex determination precision of 52.3%. No frontal sinus parameter reached a statistically significant level for sex determination in the ⩾ 50 years age-group. The number of septa and scallopings were not useful in sex determination. Frontal sinus parameters did not have a high precision in sex determination among Persian adults. PMID:26980249

    Allergic Fungal Sinusitis (AFS) is a newly recognized form of benign, non invasive sinusitis the histopathologic features of which are similar to those of allergic bronchopulmonary aspergillosis. AFS is a rare condition. However, because treatment and prognosis vary widely, it is important that this disorder be recognized and differentiated from chronic bacterial sinusitis and other forms of fungal sinusitis. AFS does not discriminate by age although it is primarily found in young adults. AFS patients are usually atopic, often having a history of asthma and nasal polyposis. Many have suffered from the symptoms of chronic sinusitis for years while others have had multiple sinus surgery. Radiographs reveal the involvement of multiple sinuses, often with bone destruction. Laboratory findings support an allergic state with a marked increase in eosinophilia and total IgE. At times RAST testing proves positive for fungi and immediate cutaneous reactivity to fungi is also present. Histologic review of the sinus contents reveals characteristic "allergic mucin", with numerous eosinophiles, Charcot-Leyden crystals and fungal hyphae, without any fungi tissue invasion. A wide variety of fungal agents has been implicated, although the majority belong the Dematiacee family. Those patients with allergic mucin but no documented fungi are indicated as having AFS-like syndrome. The pathogenesis of AFS is uncertain. There is controversy in the literature as to what role hypersensitivity (Gell and Coombs type I and type III responses) in infection play. To date current therapeutic recommendations include complete exenteration of all allergic mucin. Adjunctive, short-term systemic steroids often prove useful and nasal steroid spray should be continued for long term. Systemic antifungal agents are not recommended in AFS. Recurrence is common and thus close clinical, endoscopic and radiographic follow-up is important. The clinicopathologic features of one patient with AFS are reported

    The study builds on the concept of united airways, which describes the link between the upper and lower airways. Explorations of this concept have mainly related to asthma and less to chronic obstructive pulmonary disease (COPD). The aim of this study was to investigate paranasal sinus opacification at magnetic resonance imaging (MRI) in COPD, self-reported asthma and respiratory symptoms. In this cross-sectional study, 880 randomly selected participants in the Nord-Trøndelag health survey (HUNT) (mean age 57.7 years, range 50-66 years, 463 women) were investigated using MRI of the paranasal sinuses. Participants were allocated to four mutually exclusive groups: (1) COPD (n = 20), (2) asthma (n = 89), (3) respiratory symptoms (n = 199), and (4) reference group (n = 572). Paranasal sinus opacifications were categorised as mucosal thickening, polyps and retention cysts, and fluid. In each participant, measurements ≥1 mm from all sinuses were summed to give a total for each category of opacities. The sums for these three categories were further added together, and referred to as the total sum. Using the 75th percentile cut-off values, the likelihood of having paranasal sinus opacifications was more than six times higher in participants with COPD and twice as high in participants with asthma than among the reference group. Respiratory symptoms were only associated with mucosal thickening. The present study shows that paranasal sinus opacification is associated not only with asthma, but also with COPD and respiratory symptoms. This is in accordance with the united airways hypothesis, and should be kept in mind when handling patients with these conditions. PMID:26499376

    The primary goal of this anatomic study was to measure the average bone volume of the edentulous maxilla with a cone-beam computerized tomography (CBCT) scan and to determine its suitability for implant treatment without additional bone grafting. The secondary goal of the study was to estimate the degree of sinus pneumatization (SP) in reviewed CBCT scans, assess the sinus-to-maxillary bone interrelationship in edentulism, and attempt to classify maxillary sinuses based on the degree of their pneumatization. This retrospective radiographic quantitative study consisted of the analysis of CBCT scans of 30 randomly selected maxillary edentulous patients who presented in 2008-2010 to the University of the Pacific, Arthur A. Dugoni School of Dentistry, for evaluation and treatment of their edentulism. A volume of edentulous maxillary bone mesial to the maxillary sinuses (intersinal region) that can be used for a full-arch implant treatment was evaluated based on specifically selected and clinically relevant measurement criteria. There were 30 CBCT scans of maxillary edentulous patients reviewed (9 men, 21 women) with a mean age of 67.3 years (range, 41 to 92 years). The total mean maxillary bone volume (MMBV) suitable for implantation was 4 408.1 mm(3) and ranged from 1489.7 to 7263.1 mm(3). The MMBV in the study was higher than an assumed or hypothetical bone volume minimally suitable for 4-implant treatment as proposed by the authors for comparative purposes (3500 mm(3)). The degree of SP as seen on a CBCT scan (60 sinuses analyzed on panoramic images of 30 CBCT scans) had the following results in the study: SP0 (clear: not interfering with implant treatment in cases of high/small sinus), 2 sinuses or 3.3%; SP1 (mild sinus enlargement), 29 sinuses or 48.3%; SP2 (moderate SP), 16 sinuses or 26.7%; SP3 (severe SP), 9 sinuses or 15.0%; and SP4 (extreme), 4 sinuses or 6.7%. Most analyzed maxillary sinuses (47 of 60, or 78.3%) were in the clear, mild, or moderate

    Differentiation of right coronary artery (RCA) from left circumflex artery (LCxA) occlusion may be difficult since both can present an electrocardiographic pattern of inferior myocardial infarction (IMI). We studied 133 patients with IMI, 92 patients with RCA occlusion and 41 patients with LCxA occlusion. Risk factors such as previous MI, arterial hypertension, diabetes, smoking, and dislipemia, were similar for RCA and LCxA occlusions. Patients with RCA occlusion had a higher incidence of isolated IMI than patients with LCxA occlusion, 50% vs. 17%, respectively (P<0.001). Arterial hypotension was more prevalent (P<0.05) among patients with RCA (18%) rather than those with LCxA occlusion (2%). RCA occlusion presented an association with sinus bradycardia, an association not observed with LCxA occlusion (15% vs. 0%, respectively; P<0.01). Total atrioventricular block was only present among patients with RCA (18%). Proximal occlusions of the RCA presented lower heart rates (sinus bradycardia) than medial and distal occlusions (13% vs. 1% and 1%, respectively; P<0.0001 and P<0.001). Therefore, regarding patients with IMI: (1) sinus bradycardia is more frequent when the infarct-related artery is the RCA; (2) proximal occlusions of the right coronary predispose low heart rates; and (3) occlusion of the LCxA rarely induces sinus bradycardia.

    Anatomical complexity presents the main challenge in the administration of topical corticosteroid therapy to the paranasal sinus mucosa. This often leads to suboptimal drug delivery due to low concentrations of the therapeutic agent to the intended target area. The Relieva Stratus™ MicroFlow Spacer (Relieva Stratus) is a drug-eluting stent that is temporarily implanted into the ethmoid sinus. The reservoir of the stent is filled with triamcinolone acetonide, which is then slowly released from the device into the ethmoid sinus mucosa. The Relieva Stratus provides local and targeted delivery of the anti-inflammatory agent to the diseased mucosa. This minimally invasive implant is an option when treating ethmoid sinusitis. From January 2011 to November 2013, a total of 52 Relieva Stratus implantations into the ethmoidal cells were performed at the Department of Ear and Oral Diseases at Tampere University Hospital, Finland. C-arm fluoroscopy guidance was employed for 26 sinuses (13 patients) and optical image-guided surgery (IGS)-assisted insertions were performed on another 26 sinuses (13 patients). The accuracy of fluoroscopic insertion is not optimal, but this method is accurate enough to prevent the violation of the skull base and lamina papyracea. IGS enables the precise treatment of the diseased cells. From a technical perspective, IGS-guided insertion is a faster, safer and more exact procedure that guarantees the optimal positioning and efficacy of the implant. Moreover, IGS guidance does not entail the use of ionizing radiation. PMID:25325931

    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.

    In the present study, we investigated the efficacy of local anesthetics soaked non-absorbable sinus packs on pain management after functional endoscopic surgery (FESS). One hundred and fifty patients with the diagnosis of bilateral chronic sinusitis with or without nasal polyps who underwent FESS were included into the study. Their pre-operative Lund-Mackay computerized tomography (CT) Scores were similar. We applied anesthetic agents of 2 % lidocaine HCl, 0.25 % Bupivacaine HCl, 0.2 % Ropivacaine, 2 % Prilocaine and 0.9 % NaCl (Saline) in groups 1-5 onto the sinus packs after FESS. At postoperative period, acetaminophen (250 mg/5 ml) was used in 10-15 mg/kg per dose (4 times a day). Bleeding grade, operation duration, postoperative number of gauze/24 h, additional painkiller need, pain values at 1, 2, 4, 8, 12 and 24 h were noted. Lund-Kennedy endoscopic scores were also evaluated at 1st, 2nd and 4th weeks postoperatively. In saline group, 93.3 % of the patients needed additional painkiller. Whereas, in Bupivacaine group, additional painkiller use (20.0 %) is less than the other groups. In Bupivacaine group, number of gauze/24 h use was lower than lidocaine, ropivacaine and prilocaine groups. In our study, except 1st and 24th hours, pain values of groups can be written in ascending order (from less to higher) as Bupivacaine, Lidocaine, Prilocaine, Ropivacaine and Saline. In the first hour, pain values of groups can be written in ascending order (from less to higher) as Lidocaine, Prilocaine, Bupivacaine, Ropivacaine and Saline. In the 2nd week, in the Bupivacaine and Lidocaine Groups separately, postoperative Lund-Kennedy scores were lower than the Prilocaine and Saline Groups.

    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

    The representation of fundamental ideas is followed by the description of a new instillation preparation for the local treatment of sinusitis. The sterile filling material contains chloramphenicol, sulphanilamide and prednisolone in an organic, absorbable carrier substance based on gelatin. The indication, the technique of application and the results obtained up to now are mentioned. An average of 2.4 instillations was sufficient to achieve healing in 78.5% of the patients. Spontaneous closure of a great perforation occurred in some cases. It is emphasized that the surgical intervention nevertheless remains an integral part of sinusitis therapy and that the results obtained up to now should be corroborated by a greater number of cases and additional investigations.

    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

    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

    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

    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.

    Pneumatization of the maxillary sinus limits the quantity of alveolar bone available for implant placement and may result in a lack of primary stability and difficulty in achieving osseointegration. The purpose of this study was to retrospectively analyze a group of patients who had implants placed in the posterior maxilla, calculate the prevalence of sinus augmentation, and identify factors related to sinus augmentation. With institutional review board approval, dental records from a population of patients who had implants placed in the maxillary posterior region between January 2000 and December 2004 were used to create a database. Independent variables were classified as continuous (age of the patient at stage 1 implant surgery [S1], time between extraction and S1, time between extraction and sinus augmentation, and time between sinus augmentation and S1) and categorical (gender, implant failure, American Society of Anesthesiologists system classification, smoking, osteoporosis, residual crestal bone height, implant position, implant proximity, prostheses type, and implant diameter and length). The dependent variable was the incidence of a sinus augmentation procedure. Simple logistic regression was used to assess the influence of each factor on the presence of sinus augmentation (P < .05). The final database included 502 maxillary posterior implants with an overall survival rate of 93.2% over a mean follow-up period of 35.7 months. Of 502 implants, 272 (54.2%) were associated with a sinus augmentation procedure. Among variables, residual crestal bone height (P < .001), implant position (P < .001), implant proximity (P < .001), prosthesis type (P < .001), implant failure (P < .01), and implant diameter (P < .01), were statistically associated with sinus augmentation. Within the limitations of this retrospective study, the results suggest that more than half (54.2%) of the maxillary posterior implants were involved with a sinus augmentation procedure. The

    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

    Cholesteatoma is a relatively common disease entity within the middle ear or mastoid cavity but cholesteatoma of the paranasal sinuses is a rare diseases entity, especially in the maxillary sinus. As the authors recently experienced a patient of maxillary sinus cholesteatoma, the authors tried to review all the literatures previously reported on the "Cholesteatoma of the maxillary sinus." The aim of this study was to describe authors' recent experience and review previously reported patients of cholesteatoma of the maxillary sinus. Additionally, it is to describe the clinical features focusing on the computed tomography findings and to elucidate which approach may be best for complete excision. The authors thoroughly reviewed 10 patient reports written in English regarding the cholesteatoma of maxillary sinus which have been published since the 1980s. Based on authors' review, the authors suggest some conclusions. First, the diagnosis of cholesteatoma, although rare, should be considered for any slowly expansile lesion of the maxillary sinus. Second, there was no specific computed tomography finding that was helpful for the diagnosis of maxillary sinus cholesteatoma. Last, the surgical approach to cholesteatoma of the maxillary sinus should be chosen to allow visibility and complete removal according to the size, location, and extent of diseases. PMID:27171957

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

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

    Variations in the maxillary sinus anatomy of extant and fossil catarrhine primates have been extensively examined using computed tomography (CT), and have potential utility for phylogenetic analyses. This approach has also been used to demonstrate its anatomical variation in eight of the 16 extant genera of platyrrhines and the absence of the sinus in Saimiri and Cacajao. We used this approach to evaluate the three-dimensional anatomy of the maxillary sinus in all extant platyrrhine genera, and here argue the phylogenic implications of this variation. This study confirms, for the most part, previous CT studies and augments them with the six genera not studied previously: Ateles, Lagothrix, Callithrix, Cebuella, Pithecia and Chiropotes. The entire maxilla is pneumatized by the sinus in the atelines, Cebus, and Callicebus, whereas the sinus pneumatizes only the medial part of the maxilla in the callitrichines and Aotus. Pithecia has a unique conformation in which the maxillary sinus and the expanded inferior meatus pneumatize the posteromedial and anterolateral parts of the entire maxilla, respectively. Chiropotes has no sinus, and the inferior meatus possibly expands into the area between the middle meatus and medial surface of the maxilla to disturb sinus formation, as in the case of its close relative Cacajao. Finally, we argue that the sinus that pneumatizes the entire maxilla is a primitive feature in extant platyrrhines and was probably shared by the last common ancestor of the anthropoids.

    Background Ambulatory care visits for chronic sinusitis outnumber visits for acute sinusitis. The majority of these visits are with non-otolaryngologists. In order to better understand patients diagnosed with chronic sinusitis by non-otolaryngologists, we sought to determine if incident cases of chronic sinusitis diagnosed by primary care (PC) or emergency medicine (EM) providers meet diagnostic criteria. Methods Retrospective cohort. Patients were identified using administrative data, 2005–2006. The dataset was then clinically annotated based on chart review. We excluded prevalent cases. Results We identified 114 patients with newly diagnosed chronic sinusitis in EM (75) or PC settings (39). Rhinorrhea (EM 61%, PC 59%) and nasal obstruction (EM 67%, PC 64%) were common in both settings but facial fullness (EM 80%, PC 39%) and pain (EM 40%, PC 18%) were more common in the EM setting. Few patients reported symptoms of 90 days or longer (EM 6.0%, PC 24%) and no patient had evidence of inflammation on physical examination. A minority of patients received a sinus CT scan (22.8%) or nasal endoscopy (1.8%). In total only 1 patient diagnosed with chronic sinusitis met the diagnostic criteria. Conclusions Most patients diagnosed with chronic sinusitis by non-otolaryngologists do not have the condition. Caution should be used in studying chronic sinusitis using administrative data from non-otolaryngology providers as a large proportion of the patients may not actually have the disease.

    Chronic rhinosinusitis (CRS) is the major disorder of the upper airways, affecting about 10-15% of the total population. Topical treatment regimens show only modest efficacy, because drug delivery to the posterior nose and paranasal sinuses is still a challenge. Therefore, there is a high rate of functional endoscopic sinus surgery in CRS patients. Most nasally administered aerosolized drugs, like nasal pump sprays, are efficiently filtered by the nasal valve and do not reach the posterior nasal cavity and the sinuses, which are poorly ventilated. However, as highlighted in this review, sinus ventilation and paranasal aerosol delivery can be achieved by using pulsating airflow, offering new topical treatment options for nasal disorders. Radioaerosol inhalation and imaging studies in nasal casts and in healthy volunteers have shown 4-6% of the nasally administered dose within the sinuses. In CRS patients, significant aerosol deposition in the sinus cavities was reported before sinus surgery. After surgery, deposition increased to the amount observed in healthy volunteers. In addition, compared with nasal pump sprays, retention kinetics of the radiolabel deposited in the nasal cavity was prolonged, both in healthy volunteers and in CRS patients. These efficiencies may be sufficient for topical aerosol therapies of sinus disorders and, due to the prolonged retention kinetics, may reduce application modes, but have to be proven in future clinical trials. Pulsating aerosols may offer additional new topical treatment options of nasal and sinus disorders before as well as after surgery. PMID:25084017

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

    Primary carcinoma of the frontal sinus is quite rare, with an incidence of 0.3–1.0% of all paranasal sinus carcinomas. The early diagnosis is often difficult and the condition is often mistakenly considered to involve mucoceles, pyoceles or osteomyelitis. The present study reports the case of a 66-year-old male with squamous cell carcinoma originating in the frontal sinus. The presenting symptoms were a cutaneous nodule on the left side of the forehead and a gradually progressive headache. Magnetic resonance imaging (MRI) demonstrated erosion of the ethmoid sinus, frontal lobe and orbit. The radical resection under frontal craniotomy was performed followed by post-operative radiotherapy. Six months after the surgery, the MRI examinations did not find any recurrence, and the patient currently lives symptom-free. The present study illustrates that frontal sinus cancer should be diagnosed early with caution. Total surgical resection followed by radiotherapy and chemotherapy, used singly or in combination, may result in favorable outcomes. The current study discusses the diagnosis, treatment and prognosis of the present case and reviews the associated literature to emphasize the importance of an early identification of this rare disease.

    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.

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.

    BACKGROUND Olfactory neuroblastoma (ONB), also known as esthesioneuroblastoma, is a rare malignant head and neck cancer thought to originate from the olfactory epithelium. It typically invades contiguous structures at presentation. We report a very rare case of multifocal and ectopic ONB. CASE REPORT A 41-year-old man presented with left nasal obstruction and occasional left epistaxis associated with headache. Endoscopic examination of the nasal cavities and computed tomography suggested bilateral polypoid masses. Histopathological diagnosis after endoscopic resection established bilateral olfactory neuroblastoma of the ethmoid sinuses. The patient received postoperative radiotherapy. He remains free of disease 4 years after treatment. CONCLUSIONS To the best of our knowledge this is the second documented case of multifocal ectopic olfactory neuroblastoma. Clinicians should consider ONB in the differential diagnosis of bilateral synchronous nasal and paranasal masses to avoid delayed diagnosis. Endoscopic resection of ONB could be an option in selected cases. PMID:27097989

    Background: Although sinus restoration for transverse-sigmoid sinus (TSS) dural arteriovenous fistula (DAVF) has rarely been reported over the past decade, its advantage and indication still remain unclear. Herein, we discuss the indications and technical aspects of this therapy with a review of the literature. Case Description: A 79-year-old female was referred to our department with generalized convulsion. An angiogram revealed a DAVF at the junction of the right TSS. The right sigmoid and left transverse sinuses were occluded, which resulted in remarkable leptomeningeal venous reflux and cerebral venous congestion. A preoperative computed tomography (CT) venogram precisely revealed the occluded segment of the right sigmoid sinus, which facilitated the sinus restoration with balloon percutaneous transluminal angioplasty and stenting. Conclusion: Sinus restoration is preferable in patients with severe cerebral venous congestion due to multiple sinus occlusions and/or a restricted collateral venous outlet. CT venography is useful for precise evaluation of the length and configuration of the occluded segment, which thus make it possible to evaluate the feasibility of stenting. PMID:26392914

    Summary: Alveolar rhabdomyosarcoma (RMS) has a predilection for the deep soft tissues of the extremities and mainly occurs in children. Although the tumor may originate in other sites, such as the nasal cavity or paranasal sinus, invasion of the orbit is unusual. We describe the clinicopathological features of 2 cases of alveolar RMS of the nasal cavity or paranasal sinus in adult patients with orbital extension. These cases of alveolar RMS of the nasal cavity or paranasal sinuses are described in 2 men, both in the third decade of life. These patients were evaluated with radiological studies. The histological diagnosis was confirmed by immunohistochemical methods. Treatment consisted in a combination of chemotherapy and radiation therapy following excisional biopsy. Alveolar subtype RMS is an extremely aggressive neoplasm that rarely presents in the orbit or paranasal sinuses of adults but should be considered in the differential diagnosis of tumors with this localization. Myoglobin, Myo D1, and myogenin seem to be the most specific markers for RMS. PMID:26180715

    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.

    Twenty-six patients diagnosed as having mucopyoceles or empyemas of the frontal sinus were submitted to endoscopy-aided endonasal surgery of the anterior ethmoid and the adjacent frontal sinus between April 1989 and July 1991. Eighteen patients followed-up for a period exceeding the 3 months normally required for wound healing are presented (follow-up 3-22 months, mean 11 months). The subjective assessment of the patient was good to excellent in 16 cases. Two of these patients refused endoscopic follow-up, since they felt so well that they saw no need for it. At endoscopy, the frontal sinus was highly accessible in 5 patients, while in another 8 patients with a smaller frontal ostium it was possible to explore it adequately. Two patients in whom symptoms persisted had to be submitted to transfacial revisional surgery. An increasing percentage of patients with inflammatory frontal sinus disease can be treated by endoscopic endonasal surgery followed by thorough endoscopic aftercare. PMID:1575848

    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

    Inflammatory myofibroblastic tumor (IMT) is a benign lesion composed of myofibroblasts accompanied by varying numbers of inflammatory cells. Various pathogenetic factors have been proposed, but the etiology of most IMTs remains unknown. This article presents a case of IMT occurring in the left maxillary sinus. A 24-year-old man complained of throbbing pain in the maxillary left molars and swelling of the left cheek. His maxillary left second molar was diagnosed as pulp necrosis and root canal treatment performed. After that, his symptoms continued and he was referred to the Department of Otolaryngology. Computerized tomography disclosed compact soft tissue masses in the left maxillary sinus with obstruction of maxillary ostium. Under general anesthesia, the lesions were fully excised. Histopathologically, the lesions were composed of plump or spindled myofibroblasts. Cells were immunoreactive for smooth muscle actin and β-catenin, and were negative for ALK1, CD34, and EMA. The diagnosis was IMT of left maxillary sinus. Although it is very rare, IMT should be included as a differential diagnosis in patients with compact masses in maxillary sinus. PMID:21868269

    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
