The aim of the investigation was to obtain acoustic correlates of the vocal quality of patients with vocal polyps, before and after the endolaryngeal phonomicrosurgery (EPM).
Acoustic voice tests were carried out on 46 female patients with vocal fold polyp, before the EPM intervention and 3 weeks after its completion. Acoustic voice parameters were compared with the control group without voice pathology. The results of the investigation were analyzed acoustically.
The results showed that jitter (%), shimmer (%), fundamental frequency variation (vF(0)), voice turbulence index (VTI), pitch perturbation quotient (PPQ), amplitude perturbation quotient (APQ), and NHR values significantly differentiate the patients with vocal fold polyps from a control group without any pathological changes in the larynx. All of the analyzed parameters improved significantly (P<0.05) after the phonomicrosurgical intervention and tended to reach normal values.
The acoustic voice analysis may be used for presurgical and postsurgical voice-status evaluation.
本研究旨在通过嗓音学分析，探讨声带息肉患者接受内镜显微手术（EPM）前后的声学变化。
对 46 例女性声带息肉患者进行嗓音声学测试，分别在 EPM 干预前和干预后 3 周进行。将嗓音声学参数与无嗓音病理学的对照组进行比较。对调查结果进行声学分析。
结果显示，患者的抖动（%）、晃动（%）、基频变化（vF(0)）、嗓音不稳定性指数（VTI）、音调微扰商（PPQ）、振幅微扰商（APQ）和噪声与谐噪比（NHR）值与无喉病变的对照组明显不同。所有分析参数在接受显微手术后均有显著改善（P<0.05），并趋于接近正常水平。
嗓音声学分析可用于术前和术后的嗓音状况评估。
