The surgery targets the 'trigger sites' in the nerve branches that produce headaches. These trigger sites are detected through a set of symptoms and tests.

Dr. Bahman Guyuron, emeritus professor of plastic surgery at Case School of Medicine, Cleveland, Ohio, said, "Our data demonstrate that surgery for refractory migraine headaches in the adolescent population may improve and potentially completely ameliorate symptoms for some."
For the study, the research team observed 14 teen patients, 11 females and three males, with an average age 16 years. All the teenagers had debilitating migraine attacks that continued despite recommended medications. It was observed that the average headache frequency decreased from 25 per month before surgery to five per month afterward.
Dr. Guyuron said, "This represents a large group of adolescent migraine patients with continued symptoms in spite of specialized medical treatment. Although the experience is small and preliminary, the results suggest that migraine surgery, like in adults, is safe and effective in teenaged patients. Identifying the adolescent patient who would benefit from surgery is the most important aspect of surgical intervention."
The study was published in the Plastic and Reconstructive Surgery.
