"A controversial medical procedure has put Spanish neurologists on alert: a minimally invasive surgery, performed by plastic surgeons, that promises to treat migraines. In Spain, it is a niche practice, offered only by a few private clinics, but neurologists have raised the alarm after detecting a proliferation of these procedures. They warn that there is insufficient scientific evidence or even a biological explanation to justify it and urge patients not to undergo these interventions."
"This controversial procedure, more common in the United States, is a minimally invasive surgical technique that involves decompressing extracranial nerves: surgeons identify areas of pain trigger points and release the nerves they believe are compressed there. American plastic surgeons defend the effectiveness of this approach, but Spanish neurologists warn that the studies supporting this technique are of low quality, with few patients, highly heterogeneous diagnoses (not all suffer from migraines), and also varied surgical procedures."
A minimally invasive extracranial nerve decompression surgery is being offered by a few private clinics in Spain, mainly performed by plastic surgeons. Spanish neurologists and anesthesiologists caution against the procedure because of insufficient scientific evidence and a lack of a clear biological explanation. Published studies supporting the technique are described as low quality, including small patient numbers, heterogeneous diagnoses, and varied surgical methods. Proponents, primarily in the United States and among some plastic surgeons, claim symptom reduction in selected patients. The technique originated from a serendipitous observation by surgeon Bahman Guyuron after forehead lift patients reported migraine relief.
