Abstract

The lip is a crucial structure in the oral and maxillofacial region, serving vital physiological functions such as speech, swallowing, chewing, and expression. Due to the complexity of lip anatomy, function, and the various types of defects, the functional restoration and reconstruction of lip defects remain complex and challenging tasks. In this article, we summarize several methods for functional restoration and reconstruction of lip defects using local flaps that carry the depressor anguli oris muscle, as well as some free flaps. We also introduce methods for repairing extensive defects in the oral and maxillofacial region that are accompanied by lip defects using combinations of various tissue flaps.

Keywords: Depressor anguli oris; Free flap; Functional reconstruction; Lip defect.
