Taking a motor nerve from one area and moving it to connect the cut end to the facial nerve cut end can achieve dynamic reanimation. J Otolaryngol Head Neck Surg. Reanimation Surgery for Facial Nerve Paralysis NYU Langone neurotologists, neurosurgeons, and plastic surgeons, all of whom specialize in disorders that affect the nerves connecting the face and the brain, offer a variety of sophisticated surgical procedures—some pioneered at NYU Langone—that restore facial symmetry and reanimate, or restore movement to, the facial muscles. Nerve Graft Even if the facial nerve has lost function, the facial muscles remain healthy for about 18 months before beginning to atrophy due to lack of use. A cadaver study suggested the use of a partial masseter transfer, as the dissection of six cadavers revealed a favorable branching pattern of the masseter nerve, with each branch traveling in concert with a vessel pair, creating a neurovascular pedicle on which a partial muscle transposition can be based.
Pictured below are the temporalis and mandible muscles, which strictly speaking are not muscles of facial expression, but muscles of mastication. The temporalis and masseter muscles are muscles of mastication. Its location in the medial thigh permits the use of a two-team approach with one team for flap harvest and one team for preparation of the recipient site.
