支撑喉内镜联合动力系统在喉微创手术中的临床疗效

目的 探讨支撑喉内镜下联合喉动力系统在喉微创手术中的临床疗效。方法 声带病变患者215例，在支撑喉内镜数字显像系统的监视下，与动力系统驱动下的切割刀头联合运用切除声带病变，观察临床疗效并对手术前后临床检查结果以及患者嗓音障碍指数（VHI-10）进行比较。结果 215例声带病变一次切除，全部手术过程顺利，术后随访发现患者发音功能得到很好的恢复，声嘶改善满意。手术前后VHI量表评分变化有统计学意义（P<0.05）。结论 支撑喉内镜数字显像系统联合动力系统可以常规应用于喉微创手术中，具有相对安全、视野清晰、操作精确、创伤小等优点，疗效满意。

Clinical efficacy of suspension laryngeal endoscopy and powered laryngeal system in minimally invasive surgery

Abatract： Objective To evaluate the clinical effects of laryngeal endoscopy and powered laryngeal system in minimally invasive surgery. Methods 215 patients with vocal cord lesions were treated with powered laryngeal instruments under laryngeal endoscopy,Clinical efficacy was evaluated before and after the surgery,including laryngoscopy and selfassessment of Voice Handicap Index（ VHI-10）. Results The surgical exposure was excellent and the operational cut was precise and less invasive. The vocal function in 215 patients was satisfying. The voice handicap index were different between pre-operative and four weeks postoperative（ P〈0. 05）. Conclusion Laryngeal endoscopy combined with powered laryngeal system is ideal in minimally invasive surgery.
