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...

Mucocele of the sphenoid sinus is a rare disorder [1-3]. Its clinical manifestations are varied, primarily reflecting the intimate anatomic relationships between the sphenoid sinus and cranial nerves 11-VI, the cavernous sinus, internal carotid arteries, pituitary gland, and optic chiasm [2, 4-8]. Two patients presenting with cranial nerve deficits were evaluated with CT and MR imaging. CT show...

Sphenoid sinus lesions grasp the attention of Otorhinolaryngologists due to their prime location and vital surrounding structures. Once detected, these require prompt investigation identify underlying cause, usually attributed a tumor, fungal infection, sinusitis, or polyps, thus allowing tailored treatment. We report case an elderly lady whose neurological presentation lead diagnosis sphenoid ...

The giant cell tumor (GCT) or osteoclastoma is considered to be a locally aggressive benign tumor. The GCTs of the cranium represent only 1% of all GCTs and preferentially affect the sphenoid and temporal bones. We report a case of an 18-year-old male who presented with headache and diplopia. Radiological investigation shows a destructive midline mass involving the body of the sphenoid. The tum...

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...

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...

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.

The application of image-guided systems to sinus surgery is gaining in popularity. This study tried to evaluate the efficacy of image-guided surgery (IGS) in the fenestration of the sphenoid sinus in patients with chronic rhinosinusitis (CRS) who received revision functional endoscopic sinus surgery (FESS). A total of 51 CRS patients who received revision FESS incorporating IGS between January ...

For operations of the pituitary glands, the most subtle method is an intervention through the paranasal and especially through the sphenoid sinus. To avoid dangerous interference with adjacent organs and nerves, the surgeon has to orient himself in the very small sphenoid cavity and navigate across the hollow space to break through the sellar floor to the pituitary gland above. Especially in re...
