Facial palsy is a common and frequent disease that can occur at any age, and is common among middle-aged and young people, and can occur throughout the year, and is common in winter and spring, and is one of the most important diseases threatening human health. Its incidence is on the rise. Although facial palsy does not endanger the life of patients, the face of the disease directly affects the beauty of the patient’s appearance, and the disorder of the five senses can bring physical and psychological discomfort to patients, thus affecting their life, work and social life. Therefore, patients often require a complete cure as soon as possible. 1.What is facial palsy? Facial palsy means facial muscle paralysis, which is caused by damage to the facial nerve that governs the facial muscles, so it is also called facial nerve paralysis. Symptoms of facial palsy: paralysis of the facial muscles, drooping of the corners of the mouth and skewing to the healthy side, lacrimation or salivation, shallowing, disappearance or deepening of the nasolabial fold, or enlargement of the eye fissure, disappearance of the frontal line, or inability to frown, close the eyes, show the teeth, puff the cheeks, whistle, etc. Usually, you will see some people with crooked mouths and poorly closed eyes, and it is difficult to gargle after eating, or feel numbness in the face, especially when laughing, both sides of the face look extremely asymmetrical, which are all manifestations of facial palsy. Causes of facial palsy: 1. Infection: about 42.5% of the incidence. (1) Infectious lesions are mostly caused by the activation of herpes zoster (VZV) that is latent in the dormant state within the sensory ganglion of facial nerve. In addition, meningitis, mumps, influenza, scarlet fever, malaria, polyangiitis, and local infections can be caused. (2) Lyme (Lyme) disease is a tick-borne infectious disease. The disease is regional in nature and is mostly seen in summer. People living in forested areas and villages are more likely to develop the disease. (3) Otogenic diseases such as otitis media, labyrinthitis, mastoiditis, and septic inflammation of the temporal bone. 2. Idiopathic (often called Bell’s palsy): accounting for about 30.3% of the incidence, Bell’s palsy is caused by fatigue, cold and wind behind the face and ears. 3, tumor: about 5.5% of the incidence, the tumor itself and surgical removal of tumors can cause. Tumors include: auditory neuroma, parotid adenoma, primary cholesteatoma and jugular bulb tumor. 4.Neurogenic: about 13.5% of the incidence, caused by cerebrovascular disease, intracranial, non-traumatic neurogenic. 5, traumatic : about 8.2% of the incidence, temporal bone fracture, facial trauma, surgery and injection of neurotoxic drugs in the facial nerve distribution area are the most common causes of facial palsy in traumatic. The history of peripheral facial palsy is divided into three categories: more than 75% of patients with peripheral facial palsy have mild lesions and can recover completely within 4-6 weeks without any residual symptoms. Another 15% of patients with more severe disease may recover partially after 2-3 months. Finally, about 10% of patients have a very poor recovery with more serious complications. Patients with peripheral facial palsy should be seen in a timely manner to determine the functional status of the facial nerve by an available electrodiagnostic method, and to prevent the facial nerve from progressing to complete degeneration by giving effective medication or surgery early in the course of the disease. Zhang Shuxiang, director of the Department of Otolaryngology of the Affiliated Hospital of the Armed Forces Medical College, conducted research in this area earlier in the country and applied it to clinical practice, achieving promising results. Their hospital has an advanced American Nikoli VikingQuest vehicle-mounted neurophysiological diagnosis and analysis system, which now carries out a number of neurophysiological tests including auditory brainstem response (ABR), cochlear electrogram, facial nerve electrogram, blink reflex, etc., which have important prognostic diagnostic value for facial palsy. Patients with a better prognosis as judged by electrophysiological examination can be treated conservatively. Hormones, vasodilators, neurotrophic drugs, etc. are generally used. Certain herbal medicines and physical therapy can be taken appropriately. Otherwise, early (within 21 days of onset) surgical treatment is recommended for these patients. They perform facial nerve decompression surgery by opening the facial nerve canal and cutting the facial nerve sheath to allow decompression of the edematous facial nerve, restore facial nerve microcirculation and nerve conduction, and promote nerve regeneration. This procedure is currently an effective treatment for acute severe facial palsy. It has restored charming smiles to the faces of countless patients, saying goodbye to embarrassingly crooked mouths and eyes!
