As we all know, facial palsy is a disease that causes paralysis of facial expression muscles due to damage to the facial nerve. Since there are many causes of facial paralysis, such as tumor, otitis media, trauma, herpes zoster virus infection, etc., there are many disciplines involved, such as neurology, neurosurgery, Chinese medicine, otorhinolaryngology and plastic surgery. Whether it is congenital or acquired trauma, facial palsy is characterized by crooked corners of the mouth, incomplete eyelid closure, loss of nasolabial folds, loss of facial motor function, inability to raise the eyebrows or lift up the corners of the mouth, in severe cases, corneal leukoplakia can be formed or even blindness, and salivation in the corners of the mouth when eating and drinking, which brings physiological inconvenience and psychological discomfort to the patients, and many of these patients give up their treatments after a long period of conservative treatments that fail to cure them and they cannot live and work and socialize normally. Normal life, work and social life, although traditional Chinese medicine and ENT have some effect in the early stage of facial paralysis, but after conservative treatment is ineffective for more than 2 years, patients with advanced facial paralysis must be treated by plastic surgeons in order to achieve static symmetry and dynamic relative coordination, which is an ideal choice for patients with advanced facial paralysis.
