title: Sphenoid sinus mucocele presenting with oculomotor nerve palsy and affecting the functions of trigeminal nerve: a case report.
abstract: We report a case of first-episode sphenoid mucocele successfully treated via transnasal endoscopic drainage and marsupialization of the mucocele. A 55 year-old female presented with persistent right-side facial numbness (in the areas of the first and second branches of the trigeminal nerve) and right-side ptosis. Computed tomography (CT) imaging and Magnetic resonance imaging (MRI) revealed opacification and expansion of the right-side sphenoid sinus lesion. The lesion was diagnosed as right-side sphenoid mucocele affecting the functions of the trigeminal (first and second branches), and oculomotor nerves. Transnasal endoscopic drainage and marsupialization of the mucocele result in rapid regression of these symptoms.
