AbstractThe great auricular nerve that originates from the cervical plexus and supplies sensation to the lower part of the auricle and the skin overlying the angle of the mandible has no motor component. During an elective neck dissection for a squamous cell carcinoma of the tongue, we found that the anterior division of the great auricular nerve divided, with a long branch that passed into the submandibular triangle anterior and superficial to the facial vein, and was joined on its deep surface by the marginal mandibular division of the facial nerve. Although anatomical variants of other branches of the cervical plexus have been described, this is, to our knowledge, the first time a communication between the great auricular nerve and a branch of the facial nerve has been reported outside the parotid gland.
