Abstract

Facial nerve injury during parotidectomy remains one of the most significant complications associated this operation. Preventing facial nerve injury begins with a detailed understanding of the extra-temporal course of the facial nerve beginning with identification of the main trunk at the stylomastoid foramen. Reliable anatomic landmarks are present which facilitate identification and preservation of the main trunk of the facial nerve and facilitate antegrade dissection and preservation of the facial nerve distally. This article reviews the skeletal, cartilaginous, and muscular landmarks necessary for the reliable identification of the main trunk of the facial nerve during parotid surgery. Meticulous identification of these landmarks and attention to surgical detail we'll facilitate safe identification and dissection of the facial nerve and contributes significantly to successful parotid surgery.
