Surgical procedures involving the manipulation of the airway structure have the potential to affect the quality of voice by changing the resonance properties. Regarding this, the present study was conducted to investigate the effect of rhinoplasty on the voice of professional voice users.
This cohort study was conducted on 30 professional voice users. For the purpose of the study, the patients completed the Voice Handicap Index (VHI). In addition, they were subjected to voice analysis that included the measurement of nasality in speech production (i.e., nasalance), using the nasometer II. Computerized speech lab was also utilized to examine vowels /e/ and /a/, each of which was sustained for 5 sec by the participants.
The mean VHI scores were 8.5 ± 1.98 and 7.36 ± 1.71 before and after the surgery, respectively, indicating no significant difference between the two investigated stages (Z = - 0.53, P = 0.59). However, there was a significant difference between the patients with and without preoperative obstruction in terms of the VHI score (χ= 11.06, P = 0.004). With regard to orality, it had the mean values of 16.86 ± 7.45 and 15.22 ± 7.37 before and after the surgery, respectively. Furthermore, the mean values of nasality at the pre- and post-operation stages were 59.42 ± 6.04 and 56.28 ± 10.07, respectively. The comparison between the pre- and post-surgical orality and nasality revealed no significant difference (t = 1.226, P = 0.23 and t = 0.93, P = 0.36, respectively).
Although rhinoplasty is supposed to affect voice and vocal resonation, the induced changes are not problematic for the professional voice users.

涉及气道结构操作的外科手术可能通过改变共鸣特性而影响嗓音质量。关于这一点，本研究旨在调查鼻整形术对专业嗓音使用者嗓音的影响。
本队列研究纳入了 30 名专业嗓音使用者。为了进行研究，患者完成了嗓音障碍指数（VHI）。此外，他们接受了嗓音分析，包括言语产生时鼻音的测量（即鼻共鸣值），使用 II 型鼻音计。还利用计算机语音实验室检查参与者持续 5 秒的/e/和/a/元音。
手术前和手术后的平均 VHI 评分为 8.5±1.98 和 7.36±1.71，表明两个研究阶段之间无显著差异（Z=-0.53，P=0.59）。然而，在 VHI 评分方面，术前存在阻塞的患者与无阻塞的患者之间存在显著差异（χ=11.06，P=0.004）。至于口度，手术前和手术后的平均值分别为 16.86±7.45 和 15.22±7.37。此外，术前和术后鼻音的平均值分别为 59.42±6.04 和 56.28±10.07。术前和术后口度和鼻音的比较无显著差异（t=1.226，P=0.23 和 t=0.93，P=0.36）。
尽管鼻整形术可能会影响嗓音和嗓音共鸣，但所引起的变化对专业嗓音使用者来说并无问题。
