What are the best treatments for Hemifacial Spasm (HFS)?

The most effective treatments for Hemifacial Spasm (HFS) include Botulinum toxin injections for symptom management and Microvascular Decompression (MVD) surgery for potential long-term resolution. Because Hemifacial Spasm (HFS) is often caused by a blood vessel compressing the facial nerve, treatment must be personalized by a multidisciplinary team to determine if a patient is a better candidate for recurring injections or surgical intervention.

What are the first-line treatments for Hemifacial Spasm (HFS)?

For most patients, the first-line treatment for Hemifacial Spasm (HFS) is regular intramuscular injections of Botulinum toxin (such as Botox, Dysport, or Xeomin). These injections work by temporarily paralyzing the overactive facial muscles, providing significant relief for 80% to 90% of patients. While highly effective, the effects typically wear off after 3 to 4 months, necessitating ongoing maintenance sessions.

When is surgery considered for Hemifacial Spasm (HFS)?

Microvascular Decompression (MVD) is the only curative treatment for Hemifacial Spasm (HFS) caused by neurovascular compression. During this procedure, a surgeon places a small Teflon sponge between the offending blood vessel and the facial nerve to relieve pressure. Success rates for MVD are high, with many patients experiencing immediate resolution of symptoms, though the procedure carries risks associated with brain surgery, including hearing loss or facial weakness.

Which specialists should be on my care team?

Managing Hemifacial Spasm (HFS) requires a coordinated approach. Your care team should ideally include the following professionals:

• Neurologist: Often leads the management of Botulinum toxin injection therapy.


• Neurosurgeon: Evaluates candidacy for Microvascular Decompression (MVD).


• Ophthalmologist or Otolaryngologist: Useful for managing associated eye or ear symptoms like tinnitus.


• Clinical Psychologist: Provides support for the social anxiety and isolation that can accompany facial disfigurement.

Next steps

• Consult with a board-certified neurosurgeon to discuss if imaging (like an MRI) confirms neurovascular compression.


• Track your symptoms and injection response times to share with your neurologist.


• Join the 13 members of the Hemifacial Spasm (HFS) community at DiseaseMaps.org to share experiences and coping strategies.
