What is the recovery like after an occlusal nerve-facial nerve anastomosis?

The anastomosis between the occlusal nerve and the facial nerve for facial paralysis is mainly for facial nerve defects at the central end of the facial nerve, i.e., facial nerve injuries caused by skull base fracture or removal of intracranial tumors (e.g., acoustic neuroma). Based on the investigation of the recovery of the treated patients, I found that the patients usually started to show facial muscle movement after clenching their teeth at three months after the surgery, and with active functional training, the patients could smile without clenching their teeth and could close their eyes. With active functional training, patients can smile without clenching their teeth and close their eyes. With further functional recovery, vivid facial expressions can be seen six months after surgery. The anastomosis of the occlusal and facial nerves can effectively restore the function of the paralyzed muscles, but in order to obtain satisfactory results, not only timely surgical treatment, but also active postoperative rehabilitation is required! Both are indispensable!
