Formation of a Teflon granuloma may lead to progressive dysphonia and airway compromise. Excision of the granuloma by lateral laryngotomy allows preservation of the uninvolved lamina propria. A sternothyroid muscle flap or Silastic implant to medialize the vocal fold restores a straight glottal edge and optimizes voice production. Fifteen patients underwent removal of a Teflon granuloma via a lateral approach. Analysis of data revealed improved acoustic and aerodynamic parameters of voice following surgery. Indices of acoustic perturbation were reduced, and vocal pitch normalized. While the dynamic pitch range was unchanged, the capacity to vary loudness was enhanced. Flow rates in speech, abnormally elevated before surgery, normalized after the procedure, and phonation times were significantly longer. Perceptual and stroboscopic data confirmed that voices were improved, but not normal.
聚四氟乙烯肉芽肿的形成可能导致进行性发音障碍和气道受压。通过外侧喉切开术切除肉芽肿可保留未受累的固有层。使用胸骨甲状肌瓣或硅橡胶植入物使声带内移可恢复笔直的声门边缘并优化发声。15例患者通过外侧入路切除聚四氟乙烯肉芽肿。数据分析显示术后声音的声学和空气动力学参数有所改善。声学扰动指标降低，音调恢复正常。虽然动态音调范围不变，但响度变化能力增强。术前异常升高的言语流速在术后恢复正常，发声时间明显延长。主观和频闪数据证实声音有所改善，但未恢复正常。
