目的：研究应用非接触式ＫＴＰ（５３２ｎｍ）激光治疗早期声门型恶性肿瘤的疗效及适应证的选择。方法：选择３２例局限在声门范围内的恶性肿瘤，在支撑喉镜下暴露喉腔，应用非接触式ＫＴＰ激光切除癌肿。结果：术中无出血，术后并发症少，声带切除处３～６个月又有声带样皱襞形成。喉功能良好，随访１～４年２例复发，再行激光治疗２年以上无复发。讨论：应用非接触式ＫＴＰ激光治疗局限在声门范围内的恶性肿瘤安全可靠，损伤小，术后生存质量高，具有良好的应用前景。
Objective: To study the efficacy and indications of non-contact KTP (532nm) laser in the treatment of early glottic malignant tumors. Methods: Thirty-two malignant tumors confined to the glottis were selected. Throat was exposed in the laryngoscope. Non-contact KTP laser was used to excise the tumor. Results: No intraoperative bleeding, less postoperative complications, vocal cord resection at 3 to 6 months there vocal cord-like fold formation. Laryngeal function is good, follow-up 1 to 4 years 2 cases of recurrence, and then laser treatment for more than 2 years without recurrence. Discussion: The application of non-contact KTP laser treatment of malignant tumors confined to the glottis range is safe and reliable, with less damage and high quality of life after surgery, and has good application prospect.
