RESUMO
PURPOSE: We report a complication involving a transient inversion of Bell's phenomenon observed following extensive levator resection performed to treat aponeurotic ptosis. CASE SUMMARY: A 22 year old female patient complained of ptosis of both eyelid. The levator function of both lid was good, and a normal corneal protection mechanism was observed. The patient underwent levator resection and several reoperation because of asymmetrical lid height and entropion. Inversion of Bell's phenomenon was observed in the postoperative period. Eye with Bell's phenomenon reverted to normal within 1 month after final operation, and there were no corneal erosion. Lubricating eyedrop was used frequently during the postoperative period. CONCLUSIONS: It is important to consider that abnormal cases of Bell's phenomenon sometimes manifest after repetitive and extensive levator resection and to keep a close watch on the cornea while providing it with ample lubrication.
