Facial reanimation by muscle-nerve neurotization after facial nerve sacrifice. Case report.

摘要: Summary Introduction Recovering a certain degree of mimicry after sacrifice the facial nerve is clinically recognized finding. The authors report case hemifacial reanimation suggesting phenomenon neurotization from muscle-to-nerve. Clinical A woman benefited parotidectomy with left indicated for recurrent tumor in gland. distal branches nerve, isolated at time resection, were buried masseter muscle underneath. patient recovered voluntary motricity. electromyographic analysis motor activity zygomaticus major before and block showed dependence between mimic muscles muscle. Discussion Several hypotheses have been advanced to explain spontaneous paralysis. clinical makes it possible argue favor muscle-to-nerve nerve. It illustrates quality motricity that can be obtained thanks this procedure. Conclusion describe simple implantation technique during radical recovery resting tone but also mimicry.
