Severe stages of facial paralysis can do rehabilitation. The severe stage of facial paralysis mainly refers to the acute stage of facial paralysis. In this stage, the inflammatory edema of facial nerve is gradually aggravated, which leads to the gradual aggravation of patient’s symptoms. In the acute stage of facial paralysis, it is necessary to actively control tissue edema and improve local blood circulation, so as to reduce nerve compression and restore nerve function as soon as possible to avoid serious sequelae. Within one week of the onset of the disease, glucocorticoid drugs are mainly used for treatment, and nutritive drugs and antiviral drugs can also be given. After one week, infrared rays, ultra-short wave, microwave and other means of physical therapy can be used to promote blood circulation in the face and reduce tissue edema, which can effectively reduce the symptoms of the patient, improve the condition and promote the recovery process. It is recommended that patients in the acute stage of facial paralysis should seek medical treatment as early as possible and under the guidance of professional doctors to carry out standardized treatment, so as to avoid delaying the condition and leaving sequelae.
