The corners of the mouth start twitching after the facial paralysis has healed, which may be caused by a throbbing nerve or muscle spasm.
Generally, facial muscle spasm will lead to twitching at the corner of the mouth, which is a sequela of facial paralysis. During this period of time, you should take oral nerve-nourishing drugs, such as methylcobalamin or vitamin B1, and you can also relieve facial spasms through massage and acupuncture. If the spasms continue to worsen, the patient should seek medical attention, and if necessary, surgery should be performed.
If the corners of the mouth start to twitch after facial paralysis has resolved, it is possible that the facial paralysis has not fully recovered. When the facial nerve has not been repaired, some of the nerve myelin sheath will be lost, which may lead to twitching at the corner of the mouth. At present, we mainly take drugs to relieve the pain and improve blood circulation, such as prostaglandin, to help promote the growth of facial nerve myelin sheath and speed up the recovery of facial paralysis.
Patients usually need to strengthen the warmth in life, avoid cold, do not let the face cold, otherwise it is likely to recur again. It is also necessary to exercise appropriately to improve the body’s immunity, thus reducing the recurrence rate of facial paralysis.
