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.
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.
