This study enrolled 653 patients (coblation group, n = 326; monopolar group, n = 327), including 383 male and 270 female. The average age of the patients was 30.9 ± 6.8 (range: 18–46) years. Age, sex, disease duration, and surgical indications were similar for both groups (Table 1).All patients completed 7 days of follow-up. Pain intensity in the coblation and monopolar groups was similar on postoperative days 3 and 7 (Table 1). However, the mean maximum pain scores differed significantly between the two groups on postoperative days 1 (PTH occurred in 46 patients (7.04%) and required additional surgery, the bleeding site was in the lower pole in 40 (87.0%) and in the middle portion in 6 (13.0%), primary PTH was in 30.4% (14/46) patients and secondary PTH in 69.6% (32/46). However, PTH occurred in 9.8% (32/326) patients in the coblation group (including 2.8% in primary PTH and 7.1% in secondary PTH) and 4.3% (14/327) patients in the monopolar group (including 1.5% in primary PTH and 2.8% in secondary PTH).Of the 46 patients with PTH, the lymphoid tissue of lingual extension was damaged in 86.9% (40/46) patients. In addition, of the 32 patients with PTH in the coblation group, 25 (78.1%) and 7 (21.9%) required second and third surgeries, respectively; while all the 14 patients in the monopolar group required a second surgery.
