Transient total facial nerve paralysis: an unusual complication of transoral endoscopic-assisted management of subcondylar fracture

Abstract

Endoscopic-assisted repair of subcondylar fractures is an additional tool for management; however, there is a steep learning curve. Generally, this technique allows good visualization of the fracture site for reduction through an incision with an acceptable cosmetic result. Recently, the surgical techniques and technology as well as the indications for endoscopic facial fracture repair are in development; there are few available data in the literature regarding detail complications and recovery processes following endoscopic fracture treatment. The purpose of this article was to reveal unusual complication following endoscopic repair of subcondylar fracture in terms of radiographic, photographic, and recovering orders of the facial nerve and facial reanimations. In our case, no damage to the facial nerve was observed intraoperatively, but the patient had total facial paralysis, immediately postoperatively. At long-term follow-up, the facial nerve function was recovered well within 6 months. The authors consider that transoral endoscopic-assisted open reduction constitutes a valid alternative to a transcutaneous approach for the reduction and fixation of subcondylar fractures. It provides the benefits of open reduction and internal fixation without the permanent complications, such as facial nerve injury.
