A sinonasal mucocele can develop after the obstruction of a sinus ostium, which can occur secondary to trauma, infection, a neoplasm, or an iatrogenic cause. These mucoceles typically arise in the frontal and ethmoid sinuses. Sinonasal mucoceles are epithelium-lined cysts that can gradually expand to fill a paranasal sinus. They can present with ophthalmologic, rhinologic, and neurologic symptoms. There are reports in the literature of sinonasal mucocele development after radiation for nasopharyngeal carcinoma...

PURPOSE: To present a case of optic disc swelling caused by sinusitis. METHODS: Ocular symptoms were investigated using computed tomography imaging of the facial bones to detect the relationship between the sinus inflammation and the optic nerve. RESULTS: A particular configuration of the optic nerve was detected. Optic nerve course through the inflamed sphenoidal sinus is a condition associated with a greater risk of inflammation. CONCLUSION: Sinusitis is a rare but treatable cause of optic neuritis...

The diagnosis of sphenoid sinus diseases is difficult due to nonspecific history and physical examination findings. Sphenoid sinus is a rare localization for aspergilloma. Delay in diagnosis and treatment can result in serious complications. Presently described is case of sphenoid sinus aspergilloma. Patient had been treated by department of psychiatry for many years due to sleep disturbances and headache. Clinical and radiological features of rare case of sphenoid sinus aspergilloma are discussed.

Objective  Spontaneous cerebrospinal fluid rhinorrhea (SCSFR) might be the only clinical manifestation of idiopathic intracranial hypertension (IIH), which has been historically related to overweight. Our goal was to search for an association between SCSFR and increased body weight on the one hand and SCSFR and imaging findings suggestive of IIH on the other hand. Materials and Methods  We retrospectively collected clinical and radiological data of patients operated on endoscopically for SCSFR in our institution from 1993 to 2013...

BACKGROUND: Sphenoorbital meningiomas are surgically challenging because of their nature to extend to adjacent structures. Here, we describe a case of recurrent sphenoorbital meningioma extending into the sphenoid sinus, pterygopalatine fossa, and infratemporal fossa, which was resected using combined simultaneous transcranial and endoscopic endonasal approaches. CASE DESCRIPTION: A 62-year-old man who had 15 years earlier undergone partial resection of a left sphenoorbital meningioma presented with a 1-year history of progressive proptosis of the left eye...

OBJECTIVE In the present study the authors aimed to determine preferred locations of meningiomas by avoiding descriptive analysis and instead using voxel-based lesion mapping and 3D image-rendering techniques. METHODS Magnetic resonance images obtained in 248 treatment-naïve meningioma patients with 260 lesions were retrospectively and consecutively collected. All images were registered to a 1-mm isotropic, high-resolution, T1-weighted brain atlas provided by the Montreal Neurological Institute (the MNI152), and a lesion frequency map was created, followed by 3D volume rendering to visualize the preferred locations of meningiomas in 3D...

INTRODUCTION: Sinonasal squamous cell carcinoma (SCC) accounts for <1% of all malignancies but represents 70% of sinonasal cancer. Up to 10% of SCCs are associated with inverted papilloma (IPSCC). Studies that compare patients, treatment, and outcomes of SCC and IPSCC are absent in the literature. METHODS: A retrospective review of patients with SCC and those with IPSCC at Cleveland Clinic and Indiana University from 1995 to 2015. The records were analyzed for demographics, tumor characteristics, treatment, and outcomes...

PURPOSE: There is a high incidence of abnormal sphenoid sinus changes in patients with pituitary apoplexy (PA). Their pathophysiology is currently unexplored and may reflect an inflammatory or infective process. In this preliminary study, we characterised the microbiota of sphenoid sinus mucosa in patients with PA and compared findings to a control group of surgically treated non-functioning pituitary adenomas (NFPAs). METHODS: In this prospective observational study of patients undergoing trans-sphenoidal surgery for PA or NFPA, sphenoid sinus mucosal specimens were microbiologically profiled through PCR-cloning of the 16S rRNA gene...

The authors' initial experience with the endoscopic extradural supraorbital approach to the temporal pole and adjacent area is reported. Fully endoscopic surgery using the extradural space via a supraorbital keyhole was performed for tumors in or around the temporal pole, including temporal pole cavernous angioma, sphenoid ridge meningioma, and cavernous sinus pituitary adenoma, mainly using 4-mm, 0° and 30° endoscopes and single-shaft instruments. After making a supraorbital keyhole, a 4-mm, 30° endoscope was advanced into the extradural space of the anterior cranial fossa during lifting of the dura mater...

INTRODUCTION: Frequent and broad application of endoscopic sinus surgery (ESS) in parallel with experience makes it imperative to know the anatomy and the existing pathology very well before surgery. This study examines the association between anomalies in the sphenoid sinus area in paranasal sinuses computed tomography (PNS-CT) and pathological findings and determines variations of sphenoid sinus. METHODS: A total of 200 cases (100 women, 100 men) who had PNS-CT in the emergency and radiology polyclinics within the period of one year were included in this study...

About 50% of scuba divers have suffered from barotrauma of the ears and about one-third from barotrauma of paranasal sinuses. The sphenoid sinuses are rarely involved. Vital structures, as internal carotid artery and optic nerve, adjoin the sphenoid sinus. Thus, barotrauma could lead to serious neurologic disorders, including blindness. After searching the literature (Medline) and other sources (Internet), we present some cases of sphenoid sinus barotrauma, because these injuries may be underreported and misdiagnosed due to the lack of awareness and knowledge...

An approach for total maxillectomy with endoscopic transection of the pterygoid process via the contralateral maxillary sinus is described. In total maxillectomy, the resection of the pterygoid process of the sphenoid is a key step for successful resection. However, a conventional craniofacial approach requires extensive incision in the face, elevation of the lateral cheek flap. Even after elevation of the lateral cheek flap, visualization of this region is not good. An endoscopic approach through the contralateral maxillary sinus improved visualization of the pterygoid process, and osteotomy using a diamond-drilling bar was successfully performed...
