[Microneurovascular free abductor hallucis muscle transplantation for resuscitation of facial paralysis in one stage].

After study of local anatomy in fresh cadaver the authors carried out free abductor hallucis muscle transplantation successfully in three patients with facial paralysis. In one patient the plantaris medialis vessels were anastomosed to the contralateral facial vessels and the plantaris medialis nerve was anastomosed to buccal branch of the contralateral facial nerve. In two patients the plantaris medialis vessels were anastomosed to the ipsilateral facial vessels and the plantaris medialis nerve was anastomosed to the myloidens branch from ipsilateral trigeminal nerve. The authors described the local anatomy and operative methods in details. The advantages of this operative method were also discussed.
