Estrogen-Associated Headaches Can Be Treated by Surgery: A Multicenter Retrospective Cohort Study.

BACKGROUND:Nerve decompression surgery has been successful in treating headaches refractory to traditional medical therapies. Nevertheless, a subset of patients remains unresponsive to surgical treatment. METHODS:The authors conducted a retrospective chart review of the two senior authors' (J.E.J. and W.G.A.) patient data from 2007 to 2020 to investigate differences in surgical outcomes in women reporting estrogen-associated headaches (headaches associated with menstrual period, oral contraceptives, pregnancy, or other hormonal drugs) compared with those who did not. For these two groups, the authors used the migraine headache index as the metric for headache severity and compared the mean percent change in migraine headache index score at 3 months and 1 year. RESULTS:Of the 99 female patients who underwent nerve decompression surgery and met inclusion criteria, 50 reported estrogen-associated headaches and were found to have significantly earlier age of onset ( p = 0.017) and initial presentation to clinic ( p = 0.046). At 1 year postoperatively, migraine headache index score had improved more than 80 percent in the majority of patients (67 percent), but there was a subset of patients whose score improved less than 5 percent (12.5 percent). The authors did not find a significant difference in percent change in postoperative migraine headache index score between women with estrogen-associated headaches and those without such headaches. CONCLUSIONS:Women with estrogen-associated headaches have surgical outcomes comparable to those of women without this association. Nerve decompression surgery should be offered to women experiencing estrogen-associated headaches as an option for treatment. CLINICAL QUESTION/LEVEL OF EVIDENCE:Risk, II.
