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 palsy, such as tumor, otitis media, trauma, herpes zoster virus infection, etc., many disciplines are involved, such as neurology, neurosurgery, Chinese medicine, otorhinolaryngology and plastic surgery. Whether congenital or acquired trauma, the manifestations of facial palsy are just crooked corners of the mouth, incomplete eyelid closure, loss of nasolabial folds, loss of facial motor function, inability to raise the eyebrows or lift the corners of the mouth, severe cases may form corneal leukoplakia or even blindness, salivation at the corners of the mouth when eating, etc., which bring physiological inconvenience and psychological discomfort to the patients, and many of them give up treatment after long-term conservative treatment and fail to cure, and cannot Although traditional Chinese medicine and otorhinolaryngology are useful in the early stage of facial palsy, patients with advanced facial palsy whose conservative treatment is ineffective for more than 2 years 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 palsy.
