Voice therapy has been the primary treatment for voice feminization in transfemale patients due to concerns that surgery worsens voice quality. We aim to determine the impact of Wendler glottoplasty on acoustic measures of voice.
Retrospective case series.
Transgender female patients treated for vocal feminization with Wendler glottoplasty at a single tertiary care center were identified. Pre- and postoperative measures were taken with the Kay Elemetrics Real-Time Pitch, Analysis of Dysphonia in Speech and Voice, and Multidimensional Voice Program.
Twenty-eight patients were included in this study. There were no statistically significant changes in fundamental frequency variation, peak amplitude variation, soft phonation index, noise-to-harmonics ratio, cepstral peak prominence, or cepstral spectral index of dysphonia at a significance level of P < .05. Average speaking fundamental frequency (SF0) increased from 143 Hz after voice therapy to 163 Hz after surgery (P = .0009). Lower range decreased in 61% and increased in 26% of patients. Upper range decreased in 52% and increased in 48% of patients.
Wendler glottoplasty does not worsen voice quality based on acoustic measures. Although most patients experience an increase in average SF0, effects on vocal range are variable with approximately half of patients experiencing a reduction and half experiencing an increase in upper pitch limit.

由于担心手术会恶化嗓音质量，嗓音女性化的跨性别女性患者主要采用嗓音治疗。我们旨在确定 Wendler 声门成形术对嗓音声学测量的影响。
回顾性病例系列。
在一家三级护理中心，确定了接受 Wendler 声门成形术治疗以实现嗓音女性化的跨性别女性患者。在 Kay Elemetrics Real-Time Pitch、语音和嗓音障碍分析以及多维嗓音计划中分别采集治疗前后的测量数据。
本研究共纳入 28 例患者。在基频微扰、最大幅度微扰、柔和语音指数、噪声与谐噪比、倒频谱峰突出度和嗓音障碍倒频谱指数等声学参数方面，无统计学意义上的显著变化（P <.05）。平均言语基频（SF0）在嗓音治疗后从 143Hz 增加到手术治疗后 163Hz（P =.0009）。61%的患者低频范围下降，26%的患者低频范围增加。52%的患者高频范围下降，48%的患者高频范围增加。
基于声学测量，Wendler 声门成形术不会恶化嗓音质量。尽管大多数患者的平均 SF0 增加，但嗓音范围的影响是多变的，约一半的患者的最高音域降低，一半的患者的最高音域升高。
