• A case of acquired Brown's syndrome secondary to fibrous proliferation about the trochlea and the superior oblique tendon developed following frontal sinus surgery. This syndrome is a restrictive ocular motility disorder characterized by vertical diplopia and inability to elevate the affected eye above the mid-line on medial gaze. The purpose of this report is to bring to the attention of otolaryngologists this sequela of sinus surgery, to offer suggestions for modification of surgical technique to avoid this complication, and to emphasize the importance of identifying any signs or symptoms of eye muscle dysfunction prior to surgery.
