OBJECTIVE The purpose of this study was to present the morphometry and pneumatization of the sphenoid sinus in detail for the neurosurgeon for transnasal approach to the hypophyseal tumors and especially for functional endoscopic sinus surgery. METHODS One hundred and eighty midsagittal magnetic resonance images, 48 bones and 29 hemi-sectioned cadaveric heads obtained from Ege University, Fac...

Introduction Inverted papilloma is a rare benign tumor of the nasal fossa, which usually originates from its lateral wall. Only 5% of cases demonstrate exclusive sinus involvement. Primary sphenoid sinus involvement is even rarer. Although considered a benign lesion, the tumor has a potentially invasive nature and has also been found to have an associated malignancy rate of 7 to 15%. Objectives...

Agenesis of paranasal sinuses is an uncommon finding mainly seen in the frontal and maxillary sinuses. Agenesis of sphenoid sinuses is an extremely rare condition. In this article, we present an 18-year-old female patient suffering from headache and nasal obstruction without any skeletal or cranial anomalies. Axial, coronal and sagittal computed tomography revealed absent sphenoid sinuses. Surg...

A large Rathke's cyst was marsupialized into the sphenoid sinus of a 45-year old woman who presented with headache, polydipsia, cessation of menses and diplopia. A brief review of cases is presented.

An 85-year-old man complained of a 2-month history of pain on the left side of his face. Brain computed tomography (CT) and magnetic resonance imaging/magnetic resonance angiography did not clearly show any intracranial abnormality and only showed fluid effusion in his left sphenoid sinus. Filamentous fungi were detected from the left sphenoid sinus specimen. The isolate was Scedosporium apiosp...

OBJECTIVES/HYPOTHESIS Organized hematoma (OH) is a rare non-neoplastic disease. We studied the clinical characteristics of 17 patients with sinonasal OH and those of 75 cases in the English literature. STUDY DESIGN Retrospective review of medical records and systematic review of the literature on OH. METHODS Comprehensive review of the English-language literature on OH was performed. We scr...

Aspergillus fungus can be found worldwide and is the most common fungal infection of the paranasal sinuses. Despite this ubiquity, aspergillosis of the sphenoid sinus as an isolated disease in an otherwise healthy person is quite rare. We report two cases in this article: one was a 53-year-old woman who suffered from bloody postnasal drip for 2 weeks and the other a 61-year-old woman suffered f...

Sphenoid sinus mucocoeles can stimulate a variety of pathological conditions and patients can present to a range of specialists. Because of the relative rarity of sphenoid sinus mucocoeles, diagnosis is often delayed and these lesions can progressively expand and cause direct mechanical compression on adjacent structures. We present three cases which presented with an abducens nerve palsy. Earl...
