Hemifacial spasm is a neurological and muscular disease that manifests as involuntary, painless muscle twitching on one side of the face. Lip muscle spasms are commonly used as a synonym for hemifacial spasms.
The root of hemifacial spasm varies from person to person. Sometimes, there just isn’t a good explanation for what’s happening to a patient. Most cases of hemifacial spasm can be traced back to one of these common underlying conditions:
- Injuries to the facial nerves
- A facial nerve being compressed by a tumour or a blood vessel.
- Impairment caused by multiple sclerosis (MS)
Symptoms of a hemifacial spasm include:
- Muscles on one side of the face twitch involuntarily.
- Facial muscle twitching that originates in the eye area and radiates outwards
- Initially infrequent twitching that gradually becomes more recurrent
- Physical exam
Treatment plan may include medications, surgery and botox injections
