Abstract

Benign submandibular gland tumor is a common disease in the head and neck region and can be completely removed by transcervical approach. Typical submandibular gland resection can lead to neurological complications. The most common complications are damage to the marginal mandibular branch of the facial nerve and weakening of the lower lip. We report a case of ipsilateral lower lip twitching occurring 3 months after surgery. There was no difficulty during the operation, and there were no neurologic complications immediate after surgery. However, in the present case, the patient experienced lower lip twitching paradoxically after surgery which has not been reported in the literature yet. Therefore, we reported this case with a review of relevant literature.
