Temporary or permanent damage to your facial nerve may cause a weakness or paralysis of your facial muscles.
This may affect your eyes and/or your mouth. Often facial palsy occurs on one side of your face, but it can occur on both sides.
The causes of facial palsy vary but may include:
- A viral or bacterial infection
- Nerve damage during facial surgery
- Abnormal development of the facial nerve
- Compression of the facial nerve (Bell’s palsy)
- Facial trauma during childbirth
Diagnosis and treatment of facial palsy will depend on the area and degree of your facial paralysis.
