Abstract
Innervation options for gracilis free muscle transfer in facial reanimation
Highlights
Facial paralysis is a devastating condition that can lead to significant psychological distress and functional and aesthetic impairment[1]
One of the main advantages of the masseteric nerve as a donor source for the gracilis free muscle transfer (GFMT) lies in the power that it provides, yielding greater oral commissure excursion when compared to the cross facial nerve graft (CFNG)[8,18,19,22]
Bhama et al.[18] reported on 127 GFMT for smile reanimation in patients ages 6 to 80 years old and identified decreased oral commissure excursion with CFNG innervation compared to masseteric nerve innervation (6.5 ± 2.9 mm vs. 8.7 ± 3.5 mm)
Summary
Facial paralysis is a devastating condition that can lead to significant psychological distress and functional and aesthetic impairment[1]. One of the main advantages of the masseteric nerve as a donor source for the GFMT lies in the power that it provides, yielding greater oral commissure excursion when compared to the CFNG[8,18,19,22]. Manktelow et al.[9] reported 45 GFMTs innervated by the masseteric nerve in adults and found that 89% of patients reported achieving a spontaneous smile.
