Migraine Trigger Site Surgery is All Placebo.

Area of Science:

• Neurology
• Surgical Innovation

Background:

• Surgical treatments for migraine targeting specific "trigger sites" have gained traction over the past decade.
• Techniques involve muscle removal or nerve decompression at proposed facial trigger points.

Purpose of the Study:

• To evaluate the scientific basis and efficacy of migraine trigger site surgery.
• To determine if surgical intervention offers benefits beyond placebo effects.

Main Methods:

• Review of existing literature and clinical studies on migraine trigger site surgery.
• Analysis of the evidence supporting surgical claims versus placebo mechanisms.

Main Results:

• The scientific basis for migraine trigger site surgery is considered without merit.
• A single positive placebo-controlled study had significant limitations.
• Observed outcomes are attributed to natural migraine history and placebo responses.

Conclusions:

• Migraine trigger site surgery should not be performed outside of controlled clinical trials.
• The American Headache Society advises against this surgical approach due to lack of evidence.
