Facial paralysis, also known as facial paralysis, can be divided into peripheral facial paralysis and central facial paralysis according to the etiology. When spring is warm and cold, it is easy to have peripheral facial paralysis, which is often referred to as "crooked mouth disease".

This disease is mainly caused by the sudden onset of a cold. The cold wind makes facial blood vessels spasm, leading to ischemia, edema and compression of facial nerve tissue, leading to facial paralysis. Facial nerve can also cause mouth deviation due to inflammation and viral infection. The patient's affected eyelid is not closed completely, the forehead lines disappear or become shallow, the corners of the mouth droop, the nasolabial groove becomes shallow, the affected side leaks when the cheeks swell, and food often flows out of the corners of the mouth when eating. After facial paralysis, you should go to the hospital in time for diagnosis and treatment. Most of them can recover in a short time after conservative treatment (western medicine, acupuncture, physiotherapy and Chinese medicine), and a few of them can't recover after conservative treatment, so they need facial nerve decompression surgery. Once you miss the best treatment period, you can't change your crooked face.

The key to prevention is to avoid catching cold on the face. Pay attention to keep warm to prevent colds. The wind is strong in spring, so as not to blow cold air on your face. Wash your face without cold water. Avoid freezing the lower part of the body in a very hot state, especially after drinking alcohol.
