Background: Over the past decades, instruments and techniques of the transsphenoidal approach have improved greatly. All of these procedures, whether microscopic or endoscopic, must pass through the sphenoid sinus to reach the lesions. The sphenoid sinus is surrounded by several vital anatomical structures. Knowing the details of the anatomy of the sphenoid sinus and the extent of pneumatizatio...

OBJECTIVES/HYPOTHESIS Various intranasal landmarks have been described to aid in the localization of the natural sphenoid sinus ostium. The objectives of this study are to identify the ostium location relative to the skull base and assess the relationships between the location of the ostium and sphenoid disease or pneumatization pattern. DESIGN Descriptive study. METHODS Consecutive Xoran M...

The most studied recess of the sphenoid sinus seems to be the lateral one, which is highly variable. Less attention seems to be paid to the maxillary recess, extending anterior, inferior and lateral towards the maxillary sinus. Twenty patients were referred for CT of the paranasal sinuses (axial CT), during a 3-month period. After examining the morphology of the sphenoid sinuses, the authors fo...

Trans-nasal sphenoid sinus foreign body is a rare condition. We report a case of trans-nasal gun bullet within the sphenoid sinus with breach of the floor of the sella turcica. A 42-year-old soldier presented a few weeks after a gun battle with a history of headache. The skull x-ray demonstrated a foreign body in the region of sphenoid sinus and sella. Multidetector-row CT with multiplanar refo...

A 58-year-old man presented with a six-month history of intermittent blood-stained posterior nasal discharge. Five years ago, he had a three-week episode of fitful light headaches. Nasal ventilation, olfactory sensation, and facial sensation were normal; there were no ophthalmological complaints. Coronal computed tomography (CT) scans revealed soft masses in the bilateral sphenoid sinuses with ...

Primary inverted papilloma of the sphenoid sinus is rare. Such a case, of a 42-year-old female, is reported here, discussing the clinical presentation, diagnostic clues, radiographic features, histological findings and management. In contrast to the vast majority of cases that present with nasal complaints because of lateral nasal wall involvement, the clinical presentation of inverted papillom...

Background Mucocele is an inflammatory disease caused by the retention of mucoid secretions within a paranasal sinus. Although rare, the presence of a vascular lesion inside the sphenoid sinus could determine ostium obstruction, thus causing mucocele development. Clinical Presentation An 84-year-old woman was referred to our institution due to a lesion abutting into the sphenoid sinus; she was ...

INTRODUCTION Acute isolated sphenoid sinusitis is seen in fewer than 3% of all cases of sinusitis. It is frequently misdiagnosed because of its vague symptoms and the paucity of clinical findings. We report 2 cases of isolated acute isolated sphenoid sinusitis with unusual presentations. CLINICAL PICTURE Both patients presented with acute headache, eye pain and fever, and were provisionally d...

Objective The clinical presentation of sphenoid sinusitis can be highly variable. Rarely, sphenoid sinusitis may present with cranial nerve complications due to the proximity of these structures to the sphenoid sinus. Method A case series from Rabin Medical Center and all cases of cranial nerves palsies secondary to sphenoid sinusitis that have been reported in the literature were reviewed. ...

Morphological abnormalities of left temporal and sphenoid bone were discovered in a 17-year-old boy during a post-traumatic cranial CT scan examination. The patient had not suffered from audiological disorders previously. He did not complain of hearing loss, vertigo or autophony. Further clinical investigations were normal including micro-otoscopy and nasopharyngeal endoscopy. The Valsalva mane...
