Our study aimed to reveal whether septoplasty and inferior turbinate reduction significantly impact the acoustic properties of nasalized syllables and alter subjective and objective voice parameters.
Forty patients with nasal septal deviation and bilateral grade 2 ≤ inferior turbinate hypertrophy who underwent septoplasty and bilateral inferior turbinoplasty were enrolled. Participants completed the VHI-10, VAS, and NOSE scales preoperatively and at 6 months postoperatively. Changes in VAS and NOSE scores were calculated as VAS and NOSE values. Voice recordings of the sustained vowel /a/ and the word /mini/ were analysed using MDVP. Acoustic analysis was performed with the sustained vowel /a/, and spectrographic analysis was conducted with the consonants /m/, /n/, and the vowel /i/ in /mini/. Recordings were taken preoperatively and at 6 months postoperatively. Statistical analysis compared pre- and postoperative values for significant changes using SPSS Version 21.0 (IBM Corp.; Armonk, NY, USA).
A statistically significant decrease in VAS and NOSE scores was observed at 6 months postoperatively (p < 0.05). No significant difference was found in VHI-10 scores (p > 0.05). Acoustic analysis showed a significant change in pre- and postoperative F0 values (p < 0.05), but not in jitter, jitter%, shimmer, shimmer%, and NHR (p > 0.05). Spectrographic analysis revealed significant postoperative changes in the F3 and F4 formants of consonants /m/, /n/, and vowel /i/ in the word /mini/. A significant correlation was found between postoperative changes in F3 and F4 formant values for consonants /m/ and /n/ with the VAS value. For the NOSE value, a significant correlation was found only with the change in the F3 formant value for the consonant /m/.
Nasal surgeries, particularly septo-turbinoplasty, can influence voice timbre by modifying F3 and F4, which is of notable concern for professional voice users, such as singers and actors, due to the potential impact on the singer's formant cluster and overall vocal quality. Although it may not be appropriate to generalise for all rhinological surgeries, the significant changes in the F3 and F4 formants in a specific and refined patient group suggest that caution should be exercised in such surgeries, especially for professional voice users.
我们的研究旨在揭示鼻中隔成形术和下鼻甲切除术是否会显著影响鼻音音节的声学特性，并改变主观和客观的嗓音参数。
纳入40例鼻中隔偏曲且双侧下鼻甲肥大程度为2级及以上并接受鼻中隔成形术和双侧下鼻甲成形术的患者。参与者在术前和术后6个月完成VHI - 10、VAS和NOSE量表。VAS和NOSE评分的变化以VAS和NOSE值计算。使用MDVP分析持续元音/a/和单词/mini/的语音记录。对持续元音/a/进行声学分析，对单词/mini/中的辅音/m/、/n/和元音/i/进行频谱分析。记录在术前和术后6个月进行。使用SPSS 21.0版（IBM公司；美国纽约州阿蒙克）对术前和术后的值进行统计学分析，以比较是否有显著变化。
术后6个月观察到VAS和NOSE评分有统计学意义的下降（p < 0.05）。VHI - 10评分未发现显著差异（p > 0.05）。声学分析显示术前和术后F0值有显著变化（p < 0.05），但在抖动、抖动百分比、闪烁、闪烁百分比和噪声谐波比方面无显著变化（p > 0.05）。频谱分析显示术后单词/mini/中辅音/m/、/n/和元音/i/的F3和F4共振峰有显著变化。发现辅音/m/和/n/的F3和F4共振峰术后变化与VAS值之间存在显著相关性。对于NOSE值，仅发现与辅音/m/的F3共振峰变化存在显著相关性。
鼻部手术，特别是鼻中隔 - 鼻甲成形术，可通过改变F3和F4来影响嗓音音色，这对于专业嗓音使用者，如歌手和演员来说是值得关注的，因为这可能会对歌手共振峰簇和整体嗓音质量产生潜在影响。尽管可能不适用于所有鼻科手术，但在特定且精细的患者群体中F3和F4共振峰的显著变化表明，在这类手术中应谨慎操作。
