Facial palsy is divided into two categories: central facial palsy and peripheral facial palsy. There are many causes of facial palsy. Central facial palsy is mainly caused by intracranial diseases, while peripheral facial palsy is mainly due to trauma, Bell’s palsy, and other causes. After two years of regular treatment for facial palsy, there is still no recovery and the possibility of regaining function is almost zero. Therefore, clinically, facial palsy that has not been cured after two years is called advanced facial palsy. The treatment of advanced facial palsy is mainly corrected by surgery The plastic surgery treatment of advanced facial palsy is divided into non-dynamic suspension and functional dynamic muscle reconstructive surgery. The so-called non-dynamic treatment mainly refers to: after surgery, the face is bilaterally symmetrical under static condition and no facial palsy can be seen; when the face has expression activity, bilateral asymmetry can be seen. The so-called dynamic treatment refers to the restoration of the function of the affected facial muscles through nerve transplantation or nerve-muscle flap transplantation, so that the facial expression is restored to normal, so that facial palsy cannot be seen when there are expressive activities. 1. Non-dynamic treatment By using autologous fascia or tissue substitutes (such as artificial fascia, etc.), the drooping eyelids, corners of the mouth, and cheeks are suspended to restore them to their normal position. Non-dynamic treatment allows the patient to maintain facial symmetry in a static situation, but the face will still show asymmetry when laughing. Indications: It is indicated in cases of complete old facial palsy from various causes, where nerve anastomosis, nerve grafting and muscle grafting with anastomotic vascular nerves cannot be performed. For early facial palsy static suspension surgery should not be chosen to repair it. 2.Dynamic treatment Dynamic treatment of facial palsy includes repair of facial nerve dissection, facial nerve-subungual nerve anastomosis, trans-facial nerve graft, temporal muscle flap or occlusal muscle flap transfer, and muscle transplantation with vascular nerve. For advanced facial nerve palsy, vascularized neuromuscular transplantation is recommended for those who are in good health, under 60 years of age, and have unilateral facial palsy. In the treatment of functional reconstruction of facial expression muscles, either phase I, or phase II muscle transplantation with anastomotic vascular nerve can achieve more satisfactory results for the dynamic repair of advanced facial palsy.
