The difference between facial neuritis and facial nerve paralysis is that facial neuritis refers specifically to peripheral facial paralysis, while facial nerve paralysis is a broader concept. It includes peripheral facial palsy caused by facial neuritis, as well as central facial palsy caused by cerebrovascular diseases. Therefore, the two have different clinical concepts and symptoms. Facial neuritis can involve paralysis of the entire facial muscles, including the disappearance of forehead lines and the shallowing of the nasolabial fold below the eye slit, as well as deviation of the mouth corner. Facial nerve paralysis, in addition to the symptoms caused by facial neuritis, may also include central facial palsy caused by cerebrovascular diseases. Central facial palsy does not affect the facial muscles above the eye slit, but only causes paralysis of the facial muscles below the eye slit, including shallowing of the nasolabial fold and deviation of the mouth corner. Therefore, facial nerve paralysis is a more extensive concept.

Causes of facial neuritis

The etiology of facial neuritis is not very clear, but some views suggest that viral infections can cause edema of the facial nerve, leading to compression of the nerve and resulting in inflammation. Additionally, some nonspecific inflammatory responses can also lead to edema of the facial nerve, presenting some clinical manifestations of facial paralysis. Other high-risk factors for facial neuritis include diabetes, autonomic instability, rheumatoid immune diseases, lymphoma, etc. Therefore, it is evident that the mechanisms of facial neuritis onset are unclear, with potential causes including viral infections, diabetes, central nervous system lymphoma, or autonomic instability, all of which can lead to facial neuritis. The primary symptom of facial neuritis is paralysis of the facial muscles. With standard treatment, complete recovery generally occurs within one to two months. Facial neuritis caused by tumors tends to recur and requires heightened vigilance.

Can facial neuritis eat fish?

Patients with facial neuritis who are not allergic to seafood can eat fish. Fish contains a large amount of high-quality protein, which can supplement the essential proteins needed by the human body and improve the patient's physique. Patients can also eat other lean meats and poultry eggs, and consume plenty of fresh vegetables and fruits. If a patient develops facial neuritis, they should avoid spicy and stimulating food, such as hot peppers. Active treatment should also be pursued, including the early use of corticosteroids such as dexamethasone and prednisone, as well as drugs that nourish the nerves, commonly including B vitamins, vitamin B12, vitamin B1, and derivatives of B vitamins such as adenosylcobalamin and methylcobalamin. One week after the onset, acupuncture and physiotherapy can be considered, and many patients can be clinically cured. (Medication should be used under the guidance of a physician.)

What should be paid attention to with facial neuritis?

Bell's palsy is caused by a decrease in the body's resistance, resulting in damage to the facial nerve. This damage presents clinically as symptoms of viral infection. Therefore, precautions should be based on its cause and clinical symptoms. In terms of causes, patients should enhance their resistance, engage in more physical exercise, consume foods that eliminate free radicals, and enhance their diet with high-quality protein. When going out, avoid cold exposure, wind, and re-infection. In terms of treatment, patients should adhere to medical advice and take oral medications on time. Additionally, after treatment, rehabilitation should be emphasized to prevent residual symptoms. Thus, the symptoms of Bell's palsy involve a range of conditions.

Does facial neuritis need treatment?

Bell's palsy is a nonspecific inflammatory reaction, primarily caused by impairment of the facial nerve leading to paralysis of the facial muscles. In general, if the symptoms of Bell's palsy are mild, such as slight drooping of the corner of the mouth and drooling, there is a possibility for spontaneous recovery. However, if the symptoms of Bell's palsy are severe, and the patient also has risk factors for diabetes, these symptoms mainly include noticeably shallower forehead wrinkles, weakness in opening and closing the eyes, inability to close the eyes while sleeping, and very severe facial paralysis. In such cases, spontaneous recovery is difficult, and active treatment is required. Treatment mainly includes corticosteroid drugs and B vitamins, along with some rehabilitative training. In summary, Bell's palsy can resolve on its own if the symptoms are mild; however, if the symptoms are severe, timely treatment is necessary to avoid lasting effects.

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.
