To compare the efficacy and safety of radiofrequency (RF) and cold dissection (CD) tonsillectomy.
Prospective, double-blind, controlled clinical study.
One hundred and fourteen patients underwent tonsillectomy. The RF and CD techniques were used for the right and left tonsils, respectively; the patients and examining physicians were blinded to this information to avoid bias. We compared operation times, intraoperative bleeding, and postoperative pain associated with the respective techniques.
The RF and CD techniques required similar operation times. Intraoperative bleeding was lower after RF dissection than after CD. The severity of pain did not differ between the two techniques on postoperative day 1, but was significantly lower for the CD technique than the RF technique on postoperative days 5 and 10.
The RF technique is superior to CD regarding intraoperative bleeding, but not regarding operation time or time to return to a painless dietary regimen.
比较射频（RF）扁桃体切除术和冷剥离（CD）扁桃体切除术的疗效和安全性。
前瞻性、双盲、对照临床研究。
114例患者接受扁桃体切除术。分别对右侧和左侧扁桃体采用RF和CD技术；患者和检查医生对该信息不知情以避免偏差。我们比较了各自技术的手术时间、术中出血情况以及术后疼痛情况。
RF和CD技术所需手术时间相似。RF剥离术后的术中出血少于CD术后。术后第1天，两种技术的疼痛严重程度无差异，但术后第5天和第10天，CD技术的疼痛明显低于RF技术。
RF技术在术中出血方面优于CD技术，但在手术时间或恢复无痛饮食方案的时间方面并非如此。
