Facial neuritis, known as idiopathic facial paralysis, is a common disease in neurology. The main clinical manifestations and symptoms include acute onset, peaking within several hours to days. The primary manifestation is paralysis of the expression muscles on the affected side of the face, such as diminished forehead wrinkles, inability to open the eye, furrow the brow, or weak eyelid closure. Some patients may experience pain behind the ear, and in the tympanic membrane and external ear canal. Additionally, some patients exhibit deviation of the mouth corner, air leakage when puffing or whistling, and difficulty retaining food residues while eating or leaking water while drinking. Other patients may experience loss of taste in the anterior two-thirds of the tongue, along with secretion disorders of the salivary and lacrimal glands. Overall, the diagnosis of facial neuritis is relatively straightforward, and its clinical presentation is not particularly complex. Once the diagnosis is confirmed, timely treatment is essential, and most patients can recover.

Can facial neuritis be cured?

Facial neuritis is a relatively common disease in neurology. It is mainly caused by viral infection or other nonspecific inflammatory reactions, leading to local inflammation of the facial nerve, which results in edema of the facial nerve and clinical manifestations caused by compression within the facial nerve canal. The main symptoms include shallower furrows on the affected side of the forehead, weakness in opening and closing the eyes, drooping and skewing of the mouth corner, drooling, weakness in puffing the cheeks, and air leakage when puffing the cheeks. Most patients with facial neuritis have a good prognosis, as long as the diagnosis is clear and appropriate treatment is administered in a timely manner, such as treatment with corticosteroids and B vitamins. If it is caused by a viral infection, appropriate antiviral treatment is given, and most patients can fully recover in about three months. If the condition is severe at the onset, or if the patient has risk factors such as diabetes, the prognosis is not very good. Overall, most people with facial neuritis recover well.

Can people with facial neuritis drink alcohol?

If facial neuritis occurs, one should not drink alcohol, as alcohol itself has a significant damaging effect on nerves. Patients who drink alcohol long-term can experience damage to peripheral nerves, such as numbness and weakness in the limbs. Since facial neuritis is essentially a form of peripheral neuritis, alcohol can damage the facial nerve, hence patients with facial neuritis should not drink alcohol. Patients with facial neuritis need timely treatment, which mainly includes the use of corticosteroids to suppress immune inflammatory responses and reduce facial nerve edema, significantly shortening the course of the disease; in addition, some vitamin B drugs can be used for treatment; physical therapy, rehabilitation training, acupuncture, etc., also play a role in the recovery from facial neuritis. In summary, patients with facial neuritis absolutely should not drink alcohol, as it damages the facial nerve.

What should be paid attention to for facial neuritis?

Patients with facial neuritis usually have an acute onset, with facial nerve paralysis peaking within hours or days. It mainly manifests as paralysis of the facial expression muscles, disappearance of forehead lines, inability to frown, and incomplete closure of the eyelids. Therefore, patients with facial neuritis should pay attention to eye protection since the eyelids cannot close fully. Long-term exposure and drying of the cornea make it susceptible to infection. Therefore, it is necessary to wear an eye patch for protection or use some medicinal solutions to prevent infection and protect the cornea. Additionally, since there is a viral infection, patients should also avoid being chilled. In terms of diet, it is advisable to eat light food and avoid greasy, overly rich, or excessively spicy foods.

How is facial neuritis best treated?

The treatment of facial neuritis primarily aims to improve local blood circulation, alleviate facial nerve edema, relieve nerve compression, and promote the recovery of nerve function. Therefore, its treatment includes medication, which mainly nourishes the nerves, and may also involve antiviral drugs and corticosteroids. Physiotherapy, particularly post-acute phase, can include acupuncture or infrared radiation and local heat application. Eye protection is also necessary because patients with facial neuritis may not be able to fully close their eyelids, leaving the cornea exposed and susceptible to infection. Finally, rehabilitation treatment includes acupuncture, which is also part of the mentioned physiotherapy.

How to Treat Facial Neuritis

Bell's palsy, once diagnosed, needs to be treated as early as possible, with better outcomes the earlier treatment is started. If the patient does not have any significant contraindications, corticosteroids should be used in the early stages. Common treatments include oral prednisone, typically for about ten days, or dexamethasone intravenous infusion, typically for about five to seven days. Alongside anti-inflammatory corticosteroids, nerve nourishment can be addressed with muscle injections of vitamin B1 and vitamin B12, and patients with better economic conditions can also use mouse nerve growth factor for muscle injection nerve nourishment. Additionally, if the patient has significant pain behind the ear, indicating a possible viral infection, concurrent treatment with acyclovir antiviral therapy should be administered. Later, if recovery is poor, rehabilitative treatment can be provided, including electro-acupuncture physical therapy, infrared magnetic heating, etc., all of which can promote the recovery of Bell's palsy. The overall treatment course approximately takes about 20 days, with total recovery time ranging from 20 days to two months. (Note: Medication should be used under the guidance of a physician, based on the actual conditions.)
