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.)
