Restoration of vision by surgery in cases with sphenoidal sinus cyst is discussed. In cases 1 and 2, extranasal pansinectomy was performed within 15 days after the onset of visual disturbance and a complete recovery of visual function followed. But in case 3, transseptal approach to the sphenoidal pyocele performed 21 months after the onset of the symptom, and only a transient recovery of visulal function was observed. Furthermore postoperative re-exacerbation of visual disturbance did not improve by a revision through the extranasal approach.
These clinical observations suggested that it was very important to perform extranasal pansinectomy at an early stage for cases with visual disturbance caused by a sphenoidal sinus cyst.
