Modification of the position of the angulus oris with a rotation flap and a YV flap in lip reconstruction

Abstract

Functionally, the lip serves to prevent food and drink from spilling out of the beginning of the gastrointestinal tract, and it is also used for vocalization. In addition, the lip has cosmetic importance as part of the face involved in making expressions, and in many cultures, it is considered to be sexually appealing. The results of lip reconstruction procedures must therefore be both functionally and cosmetically satisfactory. When the orbicularis oris muscle and oral mucosa are excised, functional reconstruction is prioritized. In contrast, if there are no functional problems, cosmetic reconstruction is the main focus. This case involved the reconstruction of a right upper lip defect caused by a dog bite. When the skin defect was covered with a local flap, the right angulus oris shifted medially, so we incorporated a YV flap at the right angulus oris to modify its position and allow for a cosmetically satisfactory result. We believe that this method can be used not only for cases in which asymmetry of the angulus oris is expected to occur at the time of lip reconstruction, but also for cases in which it has already occurred in the initial operation.
