不同手术方式对声带息肉术后恢复时间的观察

目的：比较支撑喉镜下采用不同功率CO2激光和常规喉显微手术切除声带息肉患者的术后嗓音恢复时间。方法：200例声带息肉患者均分为4组，分别采用常规喉显微器械和功率为2w、4W、6W的CO2激光切除声带息肉，观察手术后嗓音恢复时间。结果：所有患者均一次切除病变，术后无呼吸困难、出血等并发症。喉显微器械组和CO2激光2W组恢复时间分别为7．2d和7．6d，分别与激光6W组比较差异均有统计学意义（P〈O．05）。结论：喉显微手术和小功率CO2激光手术切除声带息肉术后恢复时间短。

Observation of postoperative recovery time with different surgical procedures for treatment of vocal polyps

Objective：To compare postoperative voice recovery time of vocal polyps treated with different pow- er levels of COz laser and conventional laryngeal microsurgery on vocal polyps. Method：Two hundred patients with vocal polyps were randomly divided into four groups , which were respectively treated with conventional laryngeal microsurgery and different power levels of CO2 laser （2 W, 4 W and 6 W）under laryngoscope. The postoperative voice recovery time were analyzed. Result： All vocal polyps were resected at one time without any serious complica- tions like dyspnea or bleeding. The postoperative voice recovery time were 7.2 days for the group of patients re- ceived conventional laryngeal microsurgery and 7.6 days for the group of patients treated with 2 W COz laser, which were both significantly different from that in the group of patients treated with 6 W COz laser（P〈0.05）. Conclusion： The postoperative recovery time of patients treated with conventional laryngeal microsurgery and small power of CO2 laser is shorter than those operated with the other larger power of CO2 laser.
