The difference between facial neuritis and facial paralysis is that the former is a disease and the latter is a category of symptoms. The main symptom of facial neuritis is facial paralysis, which is a peripheral facial paralysis. The appearance of facial paralysis is not necessarily caused by facial neuritis, but may also be caused by central diseases. 1. Facial neuritis: also known as idiopathic facial nerve paralysis, Bell’s palsy, is an acute non-specific inflammation of the facial nerve in the inner section of the facial nerve canal, which mainly manifests as weakness of one side of the facial muscles, i.e. peripheral facial paralysis. 2. Facial paralysis: refers to facial nerve paralysis, is a symptom, divided into central facial paralysis and peripheral facial paralysis. (1) Central facial paralysis: caused by damage to the facial nerve nucleus of the brainstem, patients may show paralysis of the expression muscles in the lower part of the face on the opposite side of the lesion, such as drooping of the corners of the mouth, puffing up of the cheeks and leakage of air, etc., and the upper part of the face, such as frowning, frowning and closing of the eyes, has no effect, which is commonly seen in cerebrovascular disease. (2) Peripheral facial paralysis: caused by damage to the facial nerve nucleus and the following peripheral nerves, patients may show paralysis of the facial expression muscles on the whole affected side, inability to frown, and weakness of eyelid closure, which is commonly seen in facial neuritis and other diseases. When facial muscle weakness occurs on one side of the face, it is recommended to consult a doctor in time to make a clear diagnosis and standardize the treatment, so as to avoid delaying the condition.
