Studies found only a little amount of evidence about the impact of septoplasty on the mechanism of voice production, as well as vocal cord and laryngeal mucosal changes. Nasal obstruction is a common medical issue that is linked to changes in the quality of resonance of voice. To assess patients with deviated nasal septum and inferior turbinate hypertrophy's voice alterations using laryngeal stroboscope before and after septoplasty and turbinectomy. In this prospective case-control study, patients in group A had inferior turbinate hypertrophy and a nasal septal deviation, while participants in group B were healthy controls who were matched for age and gender. All of the included patients had their laryngeal stroboscope and acoustic voice characteristics evaluated both preoperatively and three months after surgery. Only the baseline evaluation of healthy controls was done. We included 30 patients with mean age 24.43 ± 7.81 years, and males accounted for two thirds of the included cases, speech testing showed that Amplitude perturbation significantly improved post septoplasty with values < 0.05, while Fundamental frequency and NHR parameters didn't show statistically significant improvement compared to preoperative measurements and control groups. Paired comparison of laryngeal erythema, mucosal edema and mucosal waves showed significant improvement compared to preoperative laryngeal stroboscopic findings with values < 0.001 each. Significant improvements were made to septal deviation following surgery nasal obstruction caused by nasal septal deviation and inferior turbinate hypertrophy is associated with amplitude perturbation, laryngeal erythema, mucosal edema, and mucosal waves in the patients.
研究发现，关于鼻中隔成形术对发声机制以及声带和喉黏膜变化的影响，仅有少量证据。鼻塞是一个常见的医学问题，与声音共鸣质量的变化有关。目的是在鼻中隔成形术和鼻甲切除术前后，使用喉动态镜评估鼻中隔偏曲和下鼻甲肥大患者的声音改变。在这项前瞻性病例对照研究中，A组患者患有下鼻甲肥大和鼻中隔偏曲，而B组参与者是年龄和性别匹配的健康对照。所有纳入的患者在术前和术后三个月均接受了喉动态镜和声学语音特征评估。仅对健康对照进行了基线评估。我们纳入了30例平均年龄为24.43±7.81岁的患者，其中男性占纳入病例的三分之二，语音测试显示，鼻中隔成形术后振幅微扰显著改善，P值<0.05，而基频和NHR参数与术前测量值和对照组相比，未显示出统计学上的显著改善。与术前喉动态镜检查结果相比，喉红斑、黏膜水肿和黏膜波的配对比较显示有显著改善，P值均<0.001。手术后鼻中隔偏曲有显著改善，鼻中隔偏曲和下鼻甲肥大引起的鼻塞与患者的振幅微扰、喉红斑、黏膜水肿和黏膜波有关。
