Mucoceles of the sphenoid sinus are rare and may frequently remain undiagnosed until symptoms due to compression of surrounding structures set in. In such cases, the optic nerve, because of its close proximity to the sphenoid sinus, is at risk, and pressure exerted by the mucocele may result in visual impairment. A case of a sphenoid sinus mucocele with sudden-onset unilateral blindness as the ...

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 ...

Isolated sphenoid pathology is uncommon. Nasal polyps that originate from the anterior wall of the sphenoid sinus and reach the nasopharynx are called sphenochoanal polyps. The atypical location of sphenochoanal polyps leads to misdiagnosis, and surgery risks injuring the surrounding structures, such as the optic nerve, carotid artery, and brain. For the differential diagnosis of sphenochoanal ...

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.

Many and diverse sinus pathologies can present with an orbital involvement. Contrary to popular belief, uncomplicated rhinosinusitis causes rarely orbital pain or headaches. However, especially in children, acute ethmoidal rhinosinusitis can be complicated by an extension of the infection into the orbit. Also, isolated sphenoid sinusitis is often associated with significant ophthalmologic or ne...

j. 35 year old female come to your clinic c/o of left chronic nasal obstruction on nasoscope a fleshy polypoid mass noticed in the posterior choane, On CT Scan polypoid mass from left sphenoid sinus was observed with mild enhancement. k. 40 year old obese lady c/o of chronic postural headache with salty taste in her throat on CT scan la lesion was observed in left sinus of sphenoid sinus. on MR...

BACKGROUND Unilateral isolated sphenoid sinus disease (ISSD) is a rare diagnosis of the paranasal sinuses that can be associated with complications involving vascular, neurologic, and optic structures in close proximity. CASE PRESENTATION A 62 year old female presented to a hospital in Georgetown, Guyana with right lateral rectus palsy, diplopia, and a severe progressively worsening headache....
