Recovery of ocular motility after surgical intervention in orbital roof fracture-induced cranial nerve injuries.

Abstract

Background: Orbital roof fractures can lead to cranial nerve injuries, particularly affecting the oculomotor nerve (cranial nerve [CN] III) and abducens nerve (CN VI), resulting in impaired ocular motility. This case report discusses a patient with an orbital roof fracture causing CN III and CN VI paresis, who subsequently underwent surgical intervention and experienced significant improvement in ocular function.

Case description: A 25-year-old male experienced a depressed orbital roof fracture resulting from a motorcycle accident. Postaccident, he reported double vision accompanied by restricted eye movement. Surgical intervention was performed to reconstruct the bone fragments compressing the ocular muscles. Postoperative day (POD) 1, the patient exhibited improved eye movement, and the double vision had resolved. POD 6 complete recovery.

Conclusion: Timely and effective surgical intervention for orbital roof fractures involving cranial nerves can lead to significant improvements in ocular function, including resolution of diplopia and restoration of eye movement. This case underscores the importance of prompt evaluation and management of orbital injuries to prevent permanent neurological deficits.
