Question
After the onset of right-sided facial paralysis, the swelling has persisted for over a week without improvement. Despite dietary restrictions and exercise, the condition has not shown any signs of improvement. What could be the possible causes and appropriate treatment methods?
Answer
The goal of treating facial paralysis is to promote the early subsidence of regional inflammation and swelling, and to accelerate the complete recovery of neural function. For peripheral facial nerve palsy caused by viral infection, antiviral drugs, nutritional nerve drugs, corticosteroids, and vitamin B complex can be used for treatment. Additionally, protecting the exposed cornea and preventing conjunctivitis can be achieved with eye drops or ointments; gentle massage of the affected side of the face several times a day can also aid in recovery. Physical therapy commonly includes ultrashort wave therapy, low-mid frequency electrical therapy, laser therapy, and drug injections. If conservative treatment does not result in complete recovery of facial nerve palsy after three months, and if there is no response in the facial nerve conduction velocity and electromyography examination, then surgical treatment may need to be considered.
