目的 不同术式治疗声带良性病变的效果及对声带功能的影响。方法 筛选2013年4月-2015年12月在我院住院治疗的 声带良性病变患者126例，其中57例采用常规纤维喉镜手术治疗的患者纳入对照组研究范围，采用支撑喉镜联合鼻 内镜的69例患者纳入观察组研究范围，观察并比较两种术式治疗声带良性病变的效果及其对声带功能的影响。结果 观察组治疗总有效率(98.55%)高于对照组(80.70%)；同时，术后两组声带功能基频、基频微扰、振幅微扰、NNE、 HNR均有显著改善，但观察组改善程度优于对照组，上述对比差异有统计学意义(P＜0.05)；且两组术后并发症总 发生率对比差异无统计学意义(χ2 =2.886,P=0.090)。结论 较传统支撑喉镜直视声带手术，联合鼻内镜手术视野更 佳，疗效相对优越，且患者术后声带功能恢复较高。

Objective To investigate the effects of different surgical methods on vocal cord benign lesions and vocal cord function. Methods 126 cases of patients with vocal cord benign lesions treated in our hospital from Apr. 2013 to Dec. 2015 were selected, including 57 cases with routine fiberoptic laryngoscope surgery (the control group) and another 69 cases with self-retaining laryngoscope and nasal endoscope (the observation group). The effects of two kinds of surgical methods on vocal cord benign lesions and its influence on vocal cord function were observed and compared. Results The total treatment effective rate in the observation group was higher than that in the control group (98.55%vs 80.70%). The levels of fundamental frequency, fundamental frequency perturbation, amplitude perturbation, normalized noise energy (NNE) and harmonic noise ratio (HNR) were significantly improved in the two groups after treatment, and the improvement degree in the observation group was better than that in the control group (P<0.05). There was no significant difference in the total incidence rate of postoperative complications between the two groups (χ2 =2.886, P=0.090). Conclusion Compared with traditional self-retaining laryngoscope, self-retaining laryngoscope and nasal endoscope has better visual field, better efficacy and higher postoperative vocal cord function recovery.
