Facial paralysis (peripheral facial paralysis), a common clinical facial disorder, is mostly caused by inflammation of the facial nerve. It is characterized by unilateral paralysis of facial muscles and distortion of the eyes and mouth, especially when talking and laughing. Some patients also have blurred vision, hard of hearing, numbness of the tongue and loss of taste. Many people panic when they get facial paralysis, worrying that it will not be cured or will leave after-effects. In fact, if facial paralysis is diagnosed and treated correctly at an early stage, most patients can be cured completely. Of course, the recovery time varies depending on the condition. Most patients are cured in 3 weeks – 6 weeks. Some patients with more severe conditions (EMG examination shows severe damage to the facial nerve), usually caused by infection with herpes zoster virus, onset of herpes auricularis or severe behind-the-ear pain, hard of hearing, and numbness of the tongue, are very slow to recover, and usually start to recover after three months, with the possibility of leaving different degrees of sequelae. Often patients with facial paralysis ask, “Why did I get this disease?” . The onset of facial paralysis is related to the state of health of the body. Most patients suffer from weakness, fatigue, colds or wind before the onset of the disease. When the human body has low immunity, it is easy to feel the wind, cold, virus or bacteria from the outside world and cause the disease. That is what Chinese medicine says, “where evil comes from, its qi must be weak”. Many patients often ask, “Will facial paralysis recur after it is cured?” or “How come my disease is not cured? or “How come my disease recovers slower than others?”. Recurrent facial paralysis is not rare. Recurrent facial paralysis is rare, accounting for about 3% of acute facial paralysis. Recurrent or untreated facial paralysis may be associated with the following conditions: 1. Neuroma: Many patients with recurrent and prolonged facial paralysis are found to have a facial neuroma or an acoustic neuroma on imaging studies. 2. 2.Diabetes mellitus: it usually takes 3-4 months to heal. 3.Severe facial nerve injury (complicated by herpes virus). 4, Familial facial neural tube stenosis may also be a cause: in some families, the father once suffered from facial paralysis, his son may also suffer from this disease. The facial nerve canal is a bony tube through which the facial nerve and blood vessels pass. When the facial nerve is inflamed, edema can easily block the canal, compressing the nerve and leading to facial paralysis.
