Abstract
Defects to the lower lip remain surgically challenging to reconstruct. Restoration of aesthetics and function are crucial, of which the aims include restoring the tissues of the lower lip, maintaining oral competence, speech articulation, and restoring lip height and the vermillion. Further surgical techniques continue to be explored, with local flap surgery being the generally preferred method. However, many reconstructions leave the patient with pronounced deformity and morbidity. In this case report, we describe a new technique for the reconstruction of an 80% lower lip defect with an ipsilateral split zygomaticus major muscle sling, nasolabial flap, and facial artery musculomucosal flap. The reconstruction provided good oral competence, speech articulation and aesthetics, in addition to maintaining the oral commissure and lower lip height/length. Iatrogenic microstomia was avoided and zygomaticus functioning was normal. We are confident this technique will be useful to reconstructive surgeons in select cases of significant lip defects.
