The gracilis free flap was first described by Harii et al. in 1976. Since then, it has become popularized due to its use in facial reanimation. The gracilis muscle can be easily harvested around a predictable pedicle location in conjunction with the obturator nerve that provides motor innervation. This makes it ideal for nerve transfer and a variety of reinnervation procedures. The vascular supply comes from the terminal branch of the adductor artery and accompanying venae comitantes. The gracilis free flap provides a long slender muscle that is ideal as the first line option for dynamic facial reanimation as well as reconstruction of a variety of head and neck defects.
