Advanced facial palsy mostly requires surgical correction, which can be 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 conditions and no facial palsy can be seen; when the face has expressive activities, 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 can be normalized and the facial palsy cannot be seen when the facial expression activity is performed. 1. Non-dynamic treatment By using autologous fascia or tissue substitutes, 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 keep the face symmetrical under static conditions, but the face will still show asymmetry when laughing. Indications: It is suitable for cases of complete old facial palsy caused by various reasons, where nerve anastomosis, nerve grafting and muscle grafting with anastomosed vascular nerves cannot be performed. 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 graft with vascular nerve. For advanced facial nerve palsy, vascularized neuromuscular transplantation is recommended for anyone who is in good health, under 60 years of age, and has unilateral facial palsy.
