Pectoralis myocutaneous flap for chin augmentation.

Radical resection of the anterior portion of the oral cavity, including a portion of the tongue, floor of the mouth, mandible, and neck, has always been, and remains, a perplexing problem in immediate rehabilitation of the area of the oral cavity and mentum. In the past, these deformities were classified as "Andy Gump." Attempts at correction of this deformity are protracted and complex. The use of the pectoralis myocutaneous flap offers an improvement in the concept of mamagement in that it supplies a skin lining for the oral cavity and augments the chin and neck in a single-stage procedure that may be combined with the primary operation.
