Wing flap reconstruction for large defects of the lower lip

      Summary

      Full-thickness lower lip defects most often occur due to tumour resection or injury. Because the lower lip is important for both eating and speaking, reconstruction of the region must restore the structure and function of the tissue. Here, we describe a new procedure to reconstruct the lower lip, using a ‘wing flap’: a mental V–Y rotational advancement flap that contains the mental nerve. This flap can preserve the sensory innervation of the lower lip, and it allows effective reconstruction of the muscle sling. We have employed this method twice and have obtained good aesthetic and functional outcomes. No special technique is required to reconstruct the lip using this flap, and it yields a satisfactory outcome. Thus, we recommend it as an effective method for reconstruction in wide lower lip defects.
