Scarless lip rehabilitation for the adynamic lip.

Abstract

Paralysis of the marginal mandibular branch of the facial nerve can be a debilitating condition resulting in compromised speech and oral incompetence. We describe a static procedure performed to address the functional and cosmetic deficits seen with an adynamic lip. Three patients with complete facial nerve paralysis were evaluated after the scarless lip rehabilitation, a modification of the traditional wedge resection of the lower lip. The procedure is novel in that the removal of lip laxity and advancement of the contralateral innervated lip is achieved without an external facial skin incision. All 3 patients in the study reported improvement in oral competence and lip symmetry; however, articulation was less consistently affected. All 3 patients were able to drink from a glass without leaking from their oral commissure. No complications were seen in this series of patients. Oral incompetence and asymmetry are often the overlooked sequelae from complete facial nerve paralysis. Scarless lip rehabilitation of the adynamic lip is a novel, safe, and effective means to improve these functional and aesthetic deficits.
