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...

The anatomy of the sphenoid sinus, as it relates to endoscopic sinus surgery, was studied in 93 cadaver heads (186 sphenoid sinuses) using endoscopic dissections as well as sagittal sections. The relationship of the sphenoid sinuses to the carotid artery, optic nerve, floor of sella turcica, as well as other important structures, were verified and discussed. The recesses of the sinus as well as...

OBJECTIVE To report a rare case of unilateral cavernous sinus thrombosis caused by contralateral sphenoid sinusitis. CASE REPORT A 33-year-old female visited our hospital for severe, right-sided, temporal headache, chemosis, periorbital edema, and proptosis. These signs were associated with congested erythematous nasal mucosa with purulent discharge from the right superior nasal meatus. Contr...

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 ...

OBJECTIVE To evaluate variations of some anatomic structures of sellar and parasellar regions and their possible differences between genders and age groups. PATIENTS AND METHODS Magnetic resonance images (MRI) of 380 patients were performed to analyze the dimensions of the sphenoid sinus, pituitary gland, optic chiasm, intra-cavernous carotid distances, distance between columella nasal - sphe...

Amyloidosis of the skull base is a rare entity. A patient with localized amyloidosis of the sphenoid sinus presented at our institution with cerebrospinal fluid rhinorrhoea. Endoscopic excision of the lesion and multilayered obliteration of the sphenoid sinus resolved the symptoms.

A 56-year-old male was admitted with an acute headache and sudden ptosis on the right side. No ophthalmological or neurological etiologies were apparent. A mucocele of the right posterior ethmoid sinus was observed with radiology. After the marsupialization of the mucocele via a transnasal endoscopic approach, the patient's symptoms (oculomotor nerve paralysis and headache) resolved in 4 weeks....

Background: Mucoceles are slowly expanding cystic lesions with respiratory epithelium containing mucus most commonly affecting the frontal and ethmoidal sinuses. They are caused by obstruction of sinus ostium. Mucoceles exert pressure on the bony boundaries and due to the proximity to the brain and orbit extension to these areas are common. Case presentation: A case of a frontal mucocele with a...
