If the patient has facial palsy within six months, most of the patients can recover completely after active treatment, but in a small number of patients, if the treatment is not timely, the degree of facial palsy is heavy, and the facial nerve is completely damaged, there may be a small number of sequelae left, manifested as the nasolabial folds on the side of the lesion become shallow, the frontal lines become shallow, and the corners of the mouth become crooked, which are some symptoms. The recovery of facial palsy is related to the damage of facial nerve at that time. If it is mild, moderate or severe facial palsy, timely hormonal symptomatic treatment is given to reduce facial nerve edema, and most patients can recover by acupuncture in Chinese medicine at a later stage. However, if the facial palsy is severe, the recovery time may be longer, and the patient may develop complications of mouth-eye linkage during the process.
