The gracilis flap, one of the first described musculocutaneous flaps, was initially described by Orticochea in 1972, and the first report of case series involving its free transfer was published by Harii et al. in 1976 [1, 2]. The free transfer of the gracilis muscle flap, incorporating neural coaptation with the deep temporal nerve for treating patients with unresolved Bell’s palsy, was also published by Harii et al. in the same year, in a separate paper [3]. This publication marked the first clinical description of its use in facial reanimation.
