Endoscopic dissection of recipient facial nerve for vascularized muscle transfer in the treatment of facial paralysis

In order to prepare recipient facial nerve branches for neurovascular muscle, transfer in the treatment of facial paralysis, endoscopic facial nerve dissection was employed. Under endoscopy recipient facial nerve branches innervating the zygomaticus major muscle were successfully dissected. A stab incision was sufficient for nerve suture with the donor nerve. This method is preferable for young or female patients in whom conventional cheek incisions should be avoided.
