Facial nerve disorders are a group of issues leading to facial nerve damage when facial muscles droop or become weak. Facial paralysis is the most obvious outcome of the facial nerve disorders. This paralysis usually happens on just one side of the face and can be caused due to injury or trauma, head or neck tumour, stroke or even infection of the facial nerves. The symptoms include facial pain, headache or dizziness, earache, inability to speak or express, tearing or eye or dryness of eyes and mouth.
HOW IS FACIAL NERVE DISORDERS DIAGNOSED?
Abnormality of facial nerve function may result from circulatory changes, infections, tumors, or injuries. An extensive evaluation is often necessary to determine the cause of the disorder and localize the area of nerve involvement which include:
• Hearing tests
• tear test
• balance test
• Nerve Excitability Test
• Electrical test
• Electroneurography (ENoG)
HOW IS FACIAL NERVE DISORDERS TREATED?
There are no medications specifically approved to treat facial nerve disorders. Underlying medical conditions that lead to facial nerve disorder are treated specifically according to the specific condition that is responsible for the damage to the nerve. Steroid medications are the best treatment.
