Abstract:
Lower lip defects are a major challenge from a reconstructive perspective. The lower lip is an anatomical region formed by different types of tissue, and it is essential to obtain adequate functional and aesthetic results. When local tissue is available to be a donor area, it becomes the best option to repair the defect. This article's purpose is to present our experience in reconstruction of partial or transfixing total defects of the lower lip with the musculocutaneous flap of the depressor anguli oris described by Yotsuyanagi.
