Gender affirmation laryngeal and voice surgeries are components of "voice-lift" or cosmetic voice surgeries. Feminization surgery can modify vocal folds (fundamental frequency [Fo]) and vocal tract (resonance frequency). For increased pitch, vocal folds should be shorter, thinner, and tighter. Cricothyroid approximation (CTA) surgery increases tension of the vocal folds. Endoscopic procedures for pitch raising are done by shortening the length and reducing mass of vocal folds. This shortening is achieved by surgically creating anterior glottic web. Comparing the results of various open and endoscopic surgical techniques, fundamental frequency (Fo) is raised maximally and remains stable after GL as compared with CTA.
性别肯定喉部和嗓音手术是“嗓音提升”或美容嗓音手术的组成部分。女性化手术可以改变声带(基频[Fo])和声道(共振频率)。为了提高音调,声带应更短、更薄且更紧绷。环甲肌逼近(CTA)手术可增加声带的张力。通过缩短声带长度和减轻声带质量来进行内镜下音调升高手术。这种缩短是通过手术形成前声门蹼来实现的。比较各种开放手术和内镜手术技术的结果,与CTA相比,GL术后基频(Fo)升高幅度最大且保持稳定。
