title: Sternocleidomastoid muscle additionally innervated by the facial nerve: case report and review of the literature.
abstract: An aberrant nerve branch from the facial nerve, additionally to the accessory nerve and cervical rami C2 and C3, was observed innervating the sternocleidomastoid (SCM) muscle in a 75-year-old male cadaver. We consider that the anomaly occurred as the result of a fusion of the muscular compartment from the digastric and SCM muscles during development. The aberrant innervation may be the source of the misinterpretation of electromyographic findings.
