The mean follow-up was 12.39\u202fmonths. Pain intensity, headache-related disability, and depressive symptoms were assessed preoperatively and 3\u202fmonths after treatment using the Visual Analogue Scale (VAS), Migraine Disability Assessment (MIDAS), and 10-item Center for Epidemiologic Studies Depression Scale (CESD-10), respectively. Kaplan\u2013Meier analysis was used to estimate the median duration of symptom relief. Multivariable logistic regression was performed to identify factors independently associated with repeat intervention. Receiver operating characteristic analysis was used to determine an optimal cutoff, and subgroup analyses were conducted to assess the consistency of the association.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      At 3\u202fmonths, the mean VAS score decreased from 6.56\u202f\u00b1\u202f1.63 preoperatively to 1.88\u202f\u00b1\u202f1.05, MIDAS grades improved significantly, and the mean CESD-10 score decreased from 12.41\u202f\u00b1\u202f7.26 to 7.63\u202f\u00b1\u202f5.14 (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05). The proportion of patients satisfied with treatment was 87.7%. One patient experienced local anesthetic systemic toxicity, corresponding to a complication rate of 1.23%.
