Facial palsy includes central facial palsy and peripheral facial palsy. Central facial palsy is usually seen in cerebrovascular disease, while peripheral facial palsy is usually idiopathic facial nerve paralysis. Central facial palsy lesions are located above the facial nerve nucleus to the cerebral cortex and are usually caused by cerebrovascular disease, intracranial tumors, and traumatic brain injury. Peripheral facial palsy lesions occur in the facial nucleus and facial nerve. Idiopathic facial nerve palsy is the most common cause of facial palsy. The exact cause of this disease is still unclear, but it is generally believed to be related to viral infection or inflammatory response. The disease is somewhat self-healing, but early treatment can speed up the recovery of facial palsy and reduce the occurrence of sequelae. Peripheral facial palsy mostly occurs suddenly, and most patients often suddenly find gargling leakage, weakness of one cheek movement, and crookedness of the corners of the mouth when washing the face and rinsing the mouth in the early morning. The common symptoms are: loss of wrinkles on the affected side of the forehead, enlargement of the eye fissures, crooked corners of the mouth toward the healthy side, drooping corners of the mouth and skewed face are more obvious when smiling or showing teeth, and the affected side cannot make movements such as frowning, frowning, closing the eyes, puffing and pouting; when puffing the cheeks and whistling, the lips on the affected side cannot close and leak air; when eating, food residues are often left in the gap between the teeth and cheeks on the affected side, and saliva often flows out from that side. As the tear dots are ectropioned along with the lower lid, the tears do not flow out according to normal drainage. Depending on the site of facial nerve involvement, it may be accompanied by loss of taste in the anterior 2/3 of the ipsilateral tongue, auditory hypersensitivity, and impaired tear and salivary secretion. A few patients may experience discomfort in the lips and cheeks of the mouth. Some patients may have ipsilateral corneal or conjunctival injury secondary to reduced or delayed eye closure movements and incomplete eye closure, with symptoms such as eye redness and swelling. Central facial palsy is seen in the central lesion of the brain. The facial manifestation is paralysis below the facial eye fissure, no change in the frontal lines, and movements such as eye closure and frowning are not affected, while general symptoms such as weakness of other limbs, speech impairment, tongue extension deviation, and even mental coma are seen. Central facial palsy should be treated mainly for brain pathogenesis, and local treatment can be carried out for facial palsy at the same time as systemic treatment, and the local treatment methods are the same as those for peripheral facial palsy. Peripheral facial palsy can be treated with drugs combined with acupuncture, physiotherapy and rehabilitation, etc. Acupuncture treatment can unblock qi and blood, activate blood circulation and promote the recovery of facial palsy. Some opinions believe that acupuncture treatment is not appropriate within a week of the beginning of facial palsy because the facial nerve is in an edematous state during the acute phase, and acupuncture may aggravate the patient’s facial nerve edema. Some clinical studies have also found that early acupuncture intervention not only does not aggravate the patient’s condition, but also has a better prognosis for the disease. There is also controversy as to whether acupuncture aggravates spasticity. The reason for these controversies is that some doctors do not understand how to treat facial palsy with acupuncture. Professional acupuncturists will use different treatments according to the different periods of facial palsy, so going to a professional medical institution and giving early treatment to patients with facial palsy is very helpful for recovery. Therefore, facial palsy includes central facial palsy and peripheral facial palsy, both of which have similar symptoms but different causes and treatments. When you find out that you have facial palsy, you should seek medical attention in time to clarify the cause and use comprehensive treatment to effectively reduce the sequelae and shorten the recovery time.
