Microsurgery and Neuromodulation for Facial Spasms.

Area of Science:

• Neurology
• Neurosurgery

Background:

• Facial spasms encompass various conditions, with Hemifacial spasm (HFS) being a prominent type.
• HFS presents as unilateral tonic-clonic facial muscle contractions with a predictable progression.
• Distinct clinical, radiological, and electrophysiological features define HFS.

Purpose of the Study:

• To conduct a comprehensive literature review on facial spasms.
• To detail the etiopathogenesis, clinical presentation, diagnostic methods, and treatment strategies for facial spasms.
• To specifically focus on the management of Hemifacial spasm (HFS).

Main Methods:

• Extensive review of existing scientific literature on facial spasms.
• Analysis of studies pertaining to etiopathogenesis, clinical features, investigations, and management.
• Synthesis of information regarding pharmacotherapy, botulinum toxin, microvascular decompression, and neuromodulation.

Main Results:

• Primary Hemifacial spasm (HFS) treatment options include pharmacotherapy, botulinum toxin injections, and microvascular decompression surgery.
• Microvascular decompression surgery demonstrates the highest success rate for HFS, potentially reversing pathological changes.
• Other forms of facial spasms are challenging to treat, with neuromodulation emerging as a potential therapeutic avenue.

Conclusions:

• Microvascular decompression is the most effective treatment for Hemifacial spasm (HFS).
• Management of diverse facial spasm types requires tailored approaches.
• Further research into neuromodulation for refractory facial spasms is warranted.
