Background:
The World Health Organization ranked migraine as the 19th worldwide disease causing disability. Recent insights into the pathogenesis of migraine headache substantiate a neuronal hyperexcitability and inflammation involving compressed peripheral craniofacial nerves, and these trigger points can be eliminated by surgery. In this study, we report our experience with minimally invasive surgical procedures for frontal migraine headache treatment.
Methods:
From June 2011 to May 2019, we performed 70 frontal migraine decompression surgeries of both supratrochlear and supraorbital nerves (65 bilateral and 5 unilateral) by an endoscopic or transpalpebral approach. In 24 patients (34.2%), frontal migraine emerges as a secondary trigger point following primary occipital and/or temporal migraine surgery.
Results:
After a mean follow-up of 24 months (range, 3-97 months), patients with frontal trigger site migraine reported a 94% positive response to surgery (32% complete relief and 62% significant improvement); 6% had no change in their symptoms.
Conclusions:
Based on our experience, the operation has not caused any serious complication or side effects, and surgical decompression of supraorbital and supratrochlear nerves might be recommended to patients who suffer from a moderate to severe chronic frontal migraine not responding to conventional therapy.
