Patients were randomly and equally divided into a C-arm\u2013only group and an ultrasound-combined-with\u2013C-arm (ultrasound+C-arm) group, according to a random number table. After exclusions, 42 patients were analyzed. Of these, 21 patients underwent selective semilunar ganglion radiofrequency thermocoagulation via the foramen ovale guided by the C-arm alone, whereas 21 patients underwent the same procedure guided by ultrasound combined with C-arm. The number of punctures, the amount of time elapsed until the target area of the semilunar ganglion was punctured, the cumulative dose of radiation exposure, and puncture-related complications were recorded during the operation. Numerical rating scale scores and radiofrequency thermocoagulation\u2013related complications were evaluated preoperatively and at 1\u2009day, 3\u2009days, 7\u2009days, 1\u2009month, and 3\u2009months after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The number of punctures, the amount of time elapsed until the target area of the semilunar ganglion was punctured, and the cumulative dose of radiation exposure were all lower in the ultrasound+C-arm group than in the C-arm\u2013only group (all P\u2009&amp;lt;\u20090.05). No significant differences were found in numerical rating scale scores and radiofrequency thermocoagulation\u2013related complications between the two groups (P\u2009&amp;gt;\u20090.05).
