Abstract
A case of sphenoid sinus mucocele developed in a 34-year-old male is reported. The initial symptoms of the patient included visual disturbance of the left eye and headache that started about four months prior to admission. The final diagnosis of the mucocele was confirmed by laminagraphy of the sphenoid bone and a puncture of the sinus.
The patient was operated on through the transnasal approach and the left vision imporved from 20 cm. finger counting to 1.2 (1.2x + 0.25) postoperatively.
A search of pertinent literature revealed 20 cases of sphenoid mucocele so far reported in Japanese literature and these cases are discussed in reference with 63 other cases reported by Nugent.
