Many studies have looked at the effect of functional endoscopic sinus surgeries (FESS) on nasalance, nasal consonant and nasalized vowels. Only two studies investigated the effect of FESS on vocal sound quality and have not found statistically significant changes before and after operations. The aim of this study was to examine the short-term and long-term objective and subjective changes in the vocal quality of patients after FESS, comparing patients with and without nasal polyps.
Sixteen patients were recruited for voice analysis during pre-operative, within two weeks and at least three months post-operatively. Subjective questionnaire was used to assess perception of voice changes.
There were no statistically significant changes in the acoustic parameters of patients with nasal polyposis. In patients with CRS without polyps, there was a statistically significant increase in fundamental frequency (F) in nasal sound during early follow up. The changes in soft phonation index (SPI) values between the two groups were statistically significant during early follow-ups. Only patients with nasal polyposis perceived a subjective change in their voice post-operatively.
Clinicians should inform all patients, especially voice professionals about the possible effects of endoscopic sinus surgeries on their voice quality.
许多研究已经探讨了功能性内窥镜鼻窦手术（FESS）对鼻音、鼻辅音和鼻化元音的影响。只有两项研究调查了 FESS 对嗓音质量的影响，并未发现手术前后有统计学意义上的变化。本研究旨在通过比较伴有和不伴有鼻息肉的患者，检测 FESS 后患者短期和长期的嗓音质量的客观和主观变化。
16 名患者在术前、术后两周内和至少三个月后接受了嗓音分析。采用主观问卷评估嗓音变化的感知。
伴有鼻息肉的患者的声学参数没有统计学上的显著变化。在无息肉的 CRS 患者中，在早期随访中，鼻元音的基频（F）有统计学意义的增加。两组之间的软起音指数（SPI）值的变化在早期随访中具有统计学意义。只有伴有鼻息肉的患者术后主观上感觉到嗓音的变化。
临床医生应该告知所有患者，特别是嗓音专业人士，内窥镜鼻窦手术可能对其嗓音质量产生影响。
