We report a case of recurrent sphenoid mucocele successfully treated by using a powered instrument under endoscopic control. A 59-year-old male came to our clinic complaining of severe headache, right-side facial numbness (in the areas of the first and second branches of the trigeminal nerve), diplopia, and right blepharoptosis. Computed tomography (CT) imaging revealed opacification and expansion of the sphenoid sinus lesion. The lesion was diagnosed as right-side sphenoid mucocele affecting the functions of the trigeminal (first and second branches), oculomotor, and abducent nerves. Endoscopic drainage of the right-side sphenoid mucocele leads to gradual improvement of these symptoms. Approximately 1 year after the drainage procedure, the size of the enlarged sphenoid sinus ostium had decreased. The patient underwent endoscopic right-side total marsupialization of the sphenoid sinus using a powered instrument. Subsequently, the patient has presented no evidence of recurrent disease after 1 year of follow-up.
