This study compared tonsillectomy by potassium-titanyl-phosphate (KTP/532) laser with tonsillectomy by traditional dissection and snare. Eighty-three consecutive patients who were candidates for a tonsillectomy were randomly assigned to one of four groups in a prospective study. The four treatments were bilateral traditional dissection/snare tonsillectomy, bilateral KTP/532-laser tonsillectomy, left laser tonsillectomy and right dissection/snare tonsillectomy, and left dissection/snare tonsillectomy and right laser tonsillectomy. Intraoperative comparisons were made between the two methods with regard to blood loss and operating time. Postoperatively bleeding and healing time were also recorded. A questionnaire answered on a daily basis assessed the patient's pain. Disadvantages of the KTP/532 tonsillectomy included increased cost, increased total operating time as a result of increased setup time and laser malfunctions, delayed healing, and no statistically significant improvement in level of pain. The sole advantage associated with the KTP/532 laser tonsillectomy was decreased blood loss, which may be significant for patients with a coagulopathy.
本研究比较了磷酸钛钾（KTP/532）激光扁桃体切除术与传统剥离圈套扁桃体切除术。在一项前瞻性研究中，83例连续的扁桃体切除术候选患者被随机分配到四组中的一组。四种治疗方法分别是双侧传统剥离/圈套扁桃体切除术、双侧KTP/532激光扁桃体切除术、左侧激光扁桃体切除术和右侧剥离/圈套扁桃体切除术，以及左侧剥离/圈套扁桃体切除术和右侧激光扁桃体切除术。对两种方法在术中的失血情况和手术时间进行了比较。术后还记录了出血情况和愈合时间。通过每日填写的问卷评估患者的疼痛程度。KTP/532扁桃体切除术的缺点包括成本增加、由于准备时间增加和激光故障导致总手术时间延长、愈合延迟，以及疼痛程度无统计学上的显著改善。与KTP/532激光扁桃体切除术相关的唯一优点是失血减少，这对于患有凝血障碍的患者可能具有重要意义。
