The aim of this study was to evaluate changes in acoustic features of voice after septoplasty and to establish concepts of patient management and a rational therapeutic approach.
MATERIAL/METHODS: Before and one month after surgery, phonetically balanced sentences and sustained vowels a, e, and i were recorded and digitalized with MDVP (Multi Dimensional Voice Program, Kay Elemetrics) in all patients for an evaluation of nasal resonance, voice handicap index (VHI), and active anterior rhinomanometry. These parameters were estimated: average fundamental frequency (Fo), jitter percent, shimmer, noise-to-harmonics ratio (NHR), voice turbulence index (VTI), soft phonation index (SPI), degree of voicelessness (DUV), degree of voice breaks (DVB), and peak amplitude variation (vAm).
One month after surgery the data showed an improvement in all the acoustic parameters and a normalization of nasalance.
The results highlight the impact of septoplasty on nasalance and voice. In selected cases, such as severe nasal septum deviation, the decision to perform septoplasty depends on its potential effect on speech and respiratory function. An objective evaluation of voice and nasalance helps the specialist in the management of these patients.
本研究的目的是评估鼻中隔成形术后嗓音声学特征的变化，并确立患者管理概念和合理的治疗方法。
材料/方法：在所有患者中，术前及术后1个月，使用MDVP（多维嗓音程序，Kay Elemetrics）记录并数字化语音平衡句子以及持续元音a、e和i，以评估鼻腔共鸣、嗓音障碍指数（VHI）和主动前鼻测压法。评估以下参数：平均基频（Fo）、抖动百分比、闪烁、噪声与谐波比（NHR）、嗓音湍流指数（VTI）、软起音指数（SPI）、清音程度（DUV）、破音程度（DVB）和峰值幅度变化（vAm）。
术后1个月的数据显示，所有声学参数均有改善，鼻腔共鸣正常化。
结果突出了鼻中隔成形术对鼻腔共鸣和嗓音的影响。在某些特定病例中，如严重鼻中隔偏曲，进行鼻中隔成形术的决定取决于其对言语和呼吸功能的潜在影响。对嗓音和鼻腔共鸣进行客观评估有助于专科医生对这些患者的管理。
