Treatment
There are many modalities of treatment to be considered in hemifacial spasm to help control the spasms and twitching and even provide cure in some instances.
These include:
-
Botulinum injections (Botox) to temporarily paralyse the affected muscles to prevent twitching. The effects usually last several months and repeat injections are required once the benefits wear off.
-
Medication such as anticonvulsant drugs to block the signs that cause the spasms.
-
Decompression surgery to relieve pressure on the nerve caused by a blood vessel. This modality offers a chance of "cure" of hemifacial spasm.
Lifestyle changes such as reducing stress, getting plenty of sleep and limiting caffeine can also help reduce the symptoms.
