The segmental pectoralis major muscle flap: a function-preserving procedure.
A function-sparing pectoralis major muscle flap is presented. The flap is a medially based segmental transfer of a single intercostal portion of the pectoralis major muscle supplied by a single perforating branch of the internal thoracic artery. The segmental terminal nerve distribution of the medial and lateral pectoral nerves permits preservation of the remainder of the muscle in situ. Six cases of this procedure are presented with five successful outcomes. The single exception was in the loss of the distal tip when used to cover an irradiated carotid sheath to the base of the skull.
