Abstract: 【Objective】 To compare the efficacy of radiofrequency thermocoagulation and pulsed radiofrequency for the ganglion impar in treating primary perineal pain. 【Methods】 We analyzed 79 patients with primary perineal pain who underwent radiofrequency thermocoagulation (group A) and pulsed radiofrequency (group B) in the ganglion impar from January 2020 to March 2022. VAS, excellent and good rates, sleep quality, postoperative medication usage, complications, and recurrence were evaluated before and 24 h, 1 W, 1 M, 3 M and 6 M after operation. The differences between the two groups were compared. 【Results】 The VAS score of group A gradually decreased at each level after operation, and the VAS score of group B gradually increased after 24 hours of operation. The differences between the two groups began to appear 1 week after operation, and the differences further increased with the extension of time (P<0.001). In six months after follow-up, the excellent and good rates of group A (86%) was significantly higher than that of group B (22%). In addition to postoperative perineal skin numbness, group A was superior to group B in improving sleep, postoperative oral medication (pregabalin and opioids), and disease recurrence (P<0.05). 【Conclusion】 Radiofrequency thermocoagulation for the ganglion impar can improve the quality of life by reducing pain, improving the excellent and good rates, improving sleep, and reducing recurrence a medication. The effect is better than that of pulsed radiofrequency.
