Facial neuritis, also known as idiopathic facial paralysis, generally has a good prognosis for most patients. Typically, treatment involves corticosteroids, supplemented with B vitamins, along with rehabilitative physiotherapy and local acupuncture. Most patients can recover within one to two months, and many do not experience any residual effects. However, if the facial nerve paralysis is particularly severe from the onset, and the patient is elderly with additional risk factors such as diabetes, recovery may be slower, possibly taking between two to eight months. Some patients may even suffer from some degree of lasting effects. Therefore, while most cases of facial neuritis recover well, usually within one to two months, more severe cases may need up to eight months or longer for recovery.
