Background: Migraine headache surgery has been recently reported and supported by studies as management to provide long-term relief in migraine sufferers. This study aimed to monitor the long-term results of patients who underwent migraine surgery in our clinic and determine the relationship between pain and anatomical anomalies.
Methods: A prospective review was conducted of 93 patients who underwent surgery for migraine headaches performed between 2017 and 2021 by the senior author (M.U.) and had at least 12 months of follow-up. Anatomical data were obtained by recording the findings during surgery. Migraine surgery was performed bilaterally in all patients. Anatomical symmetry differences between the right and left sides were recorded.
Results: A total of 79 (84.9%) patients experienced at least 50% reduction in migraine headache. Furthermore, 13 (14%) patients reported complete elimination of migraine headache. A significant difference was found before and after surgery in Migraine Disability Assessment score, migraine headache index, frequency, duration, and pain (p < 0.001). Also, 30 (32.3%) of the patients had bilateral headaches and 63 (67.7%) had primarily unilateral headaches. Then, 51 (81%) patients with mostly unilateral headache were anatomically asymmetrical and 12 (12%) were anatomically symmetrical. Patients with mostly unilateral headache were found to be anatomically highly asymmetrical (p < 0.005).
Conclusions: This study shows that surgical treatment is effective and long-term protection and has mild complications that are easily tolerated by the patient. The fact that headache side and anatomical asymmetry were significant in this study supports the peripheral mechanism.
