Doctors employ two primary treatments for hemifacial spasm. The most effective therapy is injecting botulinum toxin into affected areas. The toxin interferes with nerves being able to stimulate muscle movement, helping relieve the repeated contractions. Botulinum may be the only treatment for hemifacial spasm needed.
The other treatment option for hemifacial spasm is surgical intervention. A procedure known as microvascular decompression removes pressure on the nerve relieving the symptoms. While often successful, some significant side effects do exist, so doctors and patients must carefully weigh benefits against risks.
The results of treatment vary with the individual. Some cases can be completely resolved and others achieve a balance with some residual symptoms that can be tolerated.
