For the radical treatment of facial palsy, facial nerve decompression surgery can be given, which is effective for patients with clinical sequelae of facial palsy. Also, for long-term treatment with poor results, anastomosis of the inferior facial nerve and facial paracentral nerve can be considered, but the efficacy of surgery is not long-lasting, and some of them can also have sequelae. Facial palsy is caused by a non-specific inflammatory reaction to the facial nerve after exposure to cold, which results in peripheral facial nerve palsy, and can result in poor eye closure, shallow nasolabial folds, and inability to puff out the cheeks. For the acute phase of facial palsy, medication should be given to reduce local inflammation and edema and promote the recovery of facial nerve function, corticosteroid treatment can be given.
