Abstract

A patient who had been complaining of slowly progressive proptosis for two months came to the authors`hospital. Brain MRI was taken promptly to show an intraorbital lesion highly suspicious of schwannoma. We performed an operation in concert with neurosurgeons in which the intraorbital mass was totally resected through orbitozygomatic and extradural approach. After the surgery, ptosis of right upper eyelid and right hypertropia of 22 prism developed as a complication. Another operation was performed 7 months after the initial resection of the mass, in which right inferior rectus muscle was recessed and a silicone sleave was inserted for right frontalis sling. No further complication developed thereafter. Presently, the patient has right hypotropia of 8 prism and only a few creases on right upper eyelid. Orbital schwannoma is a rare disease and comprises approximately 1 percent of all orbital tumors. The authors experienced postoperative double elevator palsy as well as sinus and intraorbital schwannoma. We report this case with review of the literature.
