The aim of this study was to evaluate the objective voice results of Wendler's glottoplasty in male-to-female transsexuals.
We retrospectively reviewed our patients treated with Wendler's technique with minor modifications. Glottoplasty consisted in CO(2)-laser epithelial ablation of the anterior commissure and the two vocal folds in anterior third, suturing of the two vocal folds with two stitches of 3.0 resorbable thread, and application of fibrin sealant to strengthen the suture. Voice assessment was based mainly on fundamental frequency (F(0)), frequency range, jitter, maximum phonation time, phonation quotient, estimated subglottic pressure (ESGP) grade of dysphonia (G), and voice handicap index (VHI). These measures were taken before surgery and on the last follow-up visit.
Our series included 15 patients with a mean age of 36 years. The mean follow-up period was 7.2 months. We did not observe any early complications related to the technique. The comparison between the preoperative and the postoperative measurements, using Wilcoxon signed rank test, showed a significant improvement of median F(0) from 139 to 191 Hz (P=0.006) with an increase in the grade of dysphonia (G(pre)=0.2, G(post)=1, P=0.013) and ESGP (ESGP(pre)=8.1 ± 3.2, ESGP(post)=12.0 ± 3.8, P=0.002). Other measurements, including VHI, did not show any significant differences pre- and postoperatively.
Wendler's glottoplasty can contribute to feminize the voice.
本研究旨在评估 Wendler 式声门成形术对男变女易性者的客观嗓音效果。
我们回顾性分析了采用改良 Wendler 技术治疗的患者。声门成形术包括 CO2 激光切除前联合及前 1/3 的两个声带，用 3.0 可吸收缝线缝合两个声带，并用纤维蛋白密封剂加强缝线。嗓音评估主要基于基频（F0）、频率范围、抖动、最长发音时间、发音商、估计的声门下压（ESGP）、嗓音障碍程度分级（G）和嗓音障碍指数（VHI）。这些测量值在术前和最后一次随访时进行。
我们的系列研究包括 15 名平均年龄为 36 岁的患者。平均随访时间为 7.2 个月。我们未观察到与该技术相关的任何早期并发症。使用 Wilcoxon 符号秩检验对术前和术后测量值进行比较，发现 F0 中位数从 139Hz 显著提高到 191Hz（P=0.006），同时嗓音障碍程度分级（G 术前=0.2，G 术后=1，P=0.013）和 ESGP（ESGP 术前=8.1±3.2，ESGP 术后=12.0±3.8，P=0.002）也有所提高。其他测量值，包括 VHI，术前和术后均无显著差异。
Wendler 式声门成形术有助于使男性嗓音女性化。
