This study investigated the efficacy of using the KTP/532 laser in endoscopic inferior turbinate reduction surgery.
Potasium-titanyl-phosphate (KTP/532) laser is a useful tool in endoscopic intranasal operations, due to its outstanding capabilities in hemostasis, tissue penetration, and the maneuverability of its flexible transmission optic fiber.
A total of 124 patients (male/female 73:51, mean age 38.7 +/- 12.3 years) with chronic hypertrophic rhinitis who received endoscopic KTP/532 laser inferior turbinate reduction surgery (7 Watts, continuous mode, 0.6-1-mm spots) were available for follow-up (mean follow-up period, 25.1 +/- 7.3 months). Medical records were retrospectively reviewed, and patients were interviewed with a questionnaire.
The KTP/532 laser was excellent in relieving nose obstruction caused by inferior turbinate hypertrophy; 87% of patients reported improvement. The outcomes were less promising in reducing post-nasal drip; 12.9% reported only some improvement. Under intranasal endoscopy, the risk of postoperative bleeding and complication was low.
The findings proved that, with the use of an endoscope, the KTP/532 laser appears to be an excellent alternative for treating hypertrophic inferior turbinate.
本研究探讨KTP/532激光在内镜下下鼻甲缩小手术中的疗效。
磷酸钛钾（KTP/532）激光是内镜鼻内手术中的一种有用工具，因其在止血、组织穿透以及其柔性传输光纤的可操作性方面具有出色能力。
共有124例慢性肥厚性鼻炎患者（男/女为73:51，平均年龄38.7±12.3岁）接受了内镜KTP/532激光下鼻甲缩小手术（7瓦，连续模式，光斑0.6 - 1毫米），可供随访（平均随访期为25.1±7.3个月）。对病历进行回顾性分析，并通过问卷调查对患者进行访谈。
KTP/532激光在缓解下鼻甲肥大引起的鼻塞方面效果极佳；87%的患者报告症状改善。在减少鼻后滴漏方面效果不太理想；只有12.9%的患者报告有一定改善。在内镜检查下，术后出血和并发症的风险较低。
研究结果证明，在内镜辅助下，KTP/532激光似乎是治疗肥厚性下鼻甲的一种极佳选择。
