A case in which a left oculomotor nerve schwannoma treated by en bloc resection of the lesion and grafting of the oculomotor nerve with sural nerve is presented. Recovery of nerve function was partial, but useful and cosmetically good. The last follow-up examination performed 2 years after surgery revealed recovery of function in the elevator muscle of the upper eyelid, together with slight vertical movement of the eye.
