Treating Scars of the Chin and Perioral Region.

Lip and chin scarring occurs owing to reconstruction of congenital, cancer resection, or traumatic defects. Knowledge of lip anatomy and function is critical to optimize results. Realistic expectations should be established before intervention. Scar revision and reconstruction is ideally performed with a subunit approach, placing scars along aesthetic borders and performing subunit reconstruction to camouflage scars. Surgical techniques include direct excision, scar reorientation, local flap rearrangement, pedicled flaps, and regional or free flaps. Resurfacing/adjunctive procedures play important roles in the treatment of scars. This article reviews the anatomy, patient assessment, and techniques used in scar revision of the perioral region.
