Anomalous Extratemporal Facial Nerve in Oculoauriculovertebral Spectrum

Description
Summary:Facial nerve dysfunction is common in oculoauriculovertebral spectrum (OAVS). However, the course of the nerve has rarely been described. A 23-year-old woman with OAVS underwent excision of microtic ear remnants in preparation for an osseointegrated prosthesis and suffered iatrogenic transection of the facial nerve—the pes anserinus was within the subcutaneous tissue 15 mm posterior and 15 mm cephalad to the external acoustic meatus. The patient underwent primary nerve repair and regained nearly complete preoperative function. When considering reconstruction for OAVS patients, clinicians should have a high index of suspicion for anomalous facial nerve anatomy.
