Neurovascular anatomy of sartorius muscle flaps: Implications for local transposition and facial reanimation

Abstract

BACKGROUND: The sartorius muscle is a superficial muscle of the thigh that possesses highly suitable qualities for many uses in local transposition and free muscle transfer. However, a paucity of description of the neurovascular anatomy of the sartorius has contributed to its infrequent use in these roles. METHODS: Both human and canine studies were undertaken to delineate the neurovascular anatomy of the sartorius and to determine the role for surgical delay clinically. Fifty-five human cadaveric sartorius muscles and 30 canine cadaveric sartorius muscles underwent angiographic and dissection studies, and the location and course of the vessels and nerves supplying sartorius are described.
