Facial paralysis has lasted for three weeks. It is said that the self-healing rate is high. Can it be cured?

The key is to evaluate the degree of nerve injury. Facial nerve evoked potential and electromyography can quantitatively and objectively evaluate the state of nervous system.

Facial paralysis is a common disease, commonly known as "off-line", which is mostly caused by virus infection and is a self-limiting disease. More than 85% patients recovered well, and 15% patients recovered poorly. After the facial nerve is infected by virus, the nerve will be congested and swollen. 0-3 weeks after nerve injury, the degree of nerve swelling is 1, and EMG can accurately evaluate the degree of nerve injury.

Nerve recovery time: usually the nerve injury is less than 25%: the patient begins to recover after 1-2 weeks; The injury is 25%-50%, and it begins to recover 2-3 weeks after onset; The injury is 50-75%, and it begins to recover 3-4 weeks after onset; The injury was 75-90%, and it began to recover after 4-6 weeks. The injury is more than 90%, and it usually does not recover after 8 weeks. Most patients who have not recovered obviously for more than 2 months will leave serious sequelae.

Patients with facial nerve injury less than 90% usually recover well. It is suggested that hormone and antiviral therapy should be given within 1 week after onset, and at the same time, neurotrophic vitamin B 1/B6 and mecobalamin tablets should be given. More than 90% patients with nerve injury should undergo facial nerve decompression at an early stage.
