The aim of this study was to evaluate changes in acoustic features of speech and voice after uvulopalatopharyngoplasty (UPPP) with the Harmonic Scalpel (HS), using the multidimensional voice program (MDVP) in conjunction with other tests. Before and 6 months after surgery, phonetically balanced sentences and sustained vowels a, e, i were carried out and digitalized with MDVP in all the patients, as an evaluation of nasal resonance (trough the Glatzel and the Gutzmann tests), speech articulation and voice handicap index (VHI). These parameters were estimated: average of fundamental frequency, Jitter, Shimmer, noise-to-harmonics ratio, voice turbulence index, soft phonation index, degree of voiceless, degree of voice breaks and peak amplitude variation. Six months after surgery, improvements in all the acoustic parameters, in nasalance and VHI were achieved. In our experiences UPPP, with the HS, improves speech and voice in patients affected by snoring and/or obstructive sleep apnea syndrome.
本研究旨在使用多维语音程序（MDVP）结合其他测试，评估经 Harmonic Scalpel（HS）行悬雍垂腭咽成形术（UPPP）后语音和嗓音声学特征的变化。所有患者均在术前和术后 6 个月进行语音清晰的平衡句子和/a/、/e/、/i/元音的朗读，并使用 MDVP 进行数字化，以评估鼻音共鸣（通过 Glatzel 和 Gutzmann 测试）、言语清晰度和嗓音障碍指数（VHI）。评估以下参数：基频平均值、抖动、颤动、噪声与谐波比、嗓音湍流指数、柔和发音指数、无声程度、声破次数和最大幅度变化。术后 6 个月，所有声学参数、鼻音值和 VHI 均得到改善。在我们的经验中，HS 辅助的 UPPP 可改善受打鼾和/或阻塞性睡眠呼吸暂停综合征影响的患者的语音和嗓音。
