Facial Nerve Disorders

by


1. BELL’S PALSY

Bell’s palsy is the most common cause of facial paralysis attributing to approximately 80% of facial nerve disorders. Of those patients, 15% of them experience partial facial weakness.

2. FACIAL TRAUMA

The second most common cause for facial nerve damage blunt or penetrating trauma or injury to the face leading to facial paralysis.

3. STROKE OR OTHER CENTRAL NERVOUS SYSTEM DISORDERS

A stroke can sometimes lead to facial paralysis when nerves that control facial muscles are damaged in the brain. This either happens by lack of oxygen during the stroke or excess pressure on the brain cells from bleeding. With either situation, those brain cells can be killed within only a few minutes.

4. HEAD OR NECK TUMOR

The most common type of nerve cell tumor of the head and neck are neuromas, which are growths or swellings on nerves. Though approximately 50% of all neuromas occur in the face and neck, it is still extremely rare and most of them are benign.

5. INFECTION OF EAR OR FACE

Ear infections (acute or chronic middle ear) can cause swelling or pressure on the nerves leading to weakness of the face. Problems typically subside rather quickly with medication to treat an acute infection but surgery may be needed in chronic situations.
