Transient and isolated neurogenic blepharoptosis after medial orbital wall reconstruction.

Neurogenic blepharoptosis related to orbital surgery is very rare and only 1 report was published in the literature. This report presents 1 case of transient and isolated neurogenic blepharoptosis after medial orbital wall reconstruction. A 12-year-old male patient who suffered from periorbital trauma visited our hospital with right periorbital pain. During the physical examination, mild ecchymosis and eyelid edema were reported; however, there were no signs of either limitation of ocular motion or anisocoria. On the orbital CT images, a 17 mm × 20 mm-sized medial orbital bony defect was observed and the medial rectus muscle and orbital fat were herniated. The operation was performed 12 days after injury and the transcaruncular approach was used to reach the medial orbital wall. After the operation, he had right side blepharoptosis with mild eyelid edema and ecchymosis. However, ocular movement was normal and there were no signs of anisocoria. He did not receive any additional medication for blepharoptosis and was discharged 3 days postoperation. By the ninth day of postoperative recovery, the patient still suffered from right blepharoptosis with no levator palpebrae superioris muscle function. We prescribed a low dose of oral corticosteroid and the patient was monitored on a weekly basis. Finally, he recovered completely with normal symmetric eyelid position and levator function.
