Facial neuritis, commonly known as facial nerve palsy (i.e. facial nerve paralysis), “crooked mouth” and “hanging wind”, is a disease characterized by motor dysfunction of the facial expression muscles. The general symptom is crooked mouth and eyes, and patients are often unable to perform even the most basic movements such as raising eyebrows, closing eyes and puckering mouth. So, is the swelling behind the ear facial palsy? The following is an introduction to whether swelling and pain behind the ear is facial palsy. What are the most common causes of facial palsy? It is common for facial palsy caused by traumatic brain injury. In recent years, accidents such as car accidents have caused cranio-cerebral trauma, which in turn has injured the facial nerve and led to facial palsy. If the damage to the facial nerve is found to be serious, treatment for facial palsy can be performed within a month. What is the relationship between ear and facial palsy? There is a close relationship between ear diseases and facial palsy. For example, if chronic suppurative otitis media is not cured for a long time, especially when cholesteatoma is formed, it will corrode the facial nerve canal and damage the facial nerve, resulting in symptoms such as crooked mouth and inability to close the eyes. Therefore, once a patient with otitis media has a crooked mouth, it means that the condition has worsened and he or she should be alert. To prevent and treat facial paralysis caused by ear disease, it is important to intervene early in the treatment of cholesteatoma otitis media, and if surgery is needed, it should be done as soon as possible. For facial palsy caused by viruses such as herpes zoster virus and herpes simplex virus, it is important to take advantage of the best treatment period and go to a regular hospital as soon as possible. This type of facial palsy is very effective when treated with hormone therapy. Once facial palsy occurs without early formal and correct treatment, the subsequent recovery effect is often not ideal. Therefore, the key to facial palsy treatment is to remember one word – “early”. Precautions to prevent facial palsy First of all, you should pay attention to keeping warm, try to wear a mask when you go out, avoid the direct attack of the cold wind on your face, and try not to walk against the wind. If you suffer from facial palsy, you should pay attention to adequate rest, combine work and rest, relax, and do not be impatient and irritated. Eat a light diet and do not eat cold food. The affected face and ears should be kept warm.
