This study investigated the prethyroplasty and postthyroplasty voices of patients with glottic incompetence of mobile vocal folds related to vocal fold bowing and scarring. Seventeen patients underwent vocal function evaluation preoperatively and 1 month postoperatively with videostrobolaryngoscopic examination, acoustic and aerodynamic analysis, and perceptual judgment of voice characteristics. The postoperative voice outcome in this group of patients was compared to that of a group of patients with unilateral vocal fold paralysis. Patients with vocal fold bowing showed significant improvement in glottic gap size and hoarseness after the surgery. There was minimal improvement on other test measures. Patients with vocal fold scarring exhibited worse preoperative and postoperative vocal functions, with little voice improvement after surgery. The outcome of thyroplasty type I in cases of vocal fold bowing or scarring is not as good as that in unilateral vocal fold paralysis.
本研究调查了与声带弓状变形和瘢痕形成相关的可动性声带声门功能不全患者在甲状成形术前和术后的嗓音情况。17例患者在术前及术后1个月接受了嗓音功能评估，包括视频频闪喉镜检查、声学和空气动力学分析以及嗓音特征的主观判断。将该组患者的术后嗓音结果与一组单侧声带麻痹患者的结果进行了比较。声带弓状变形患者术后声门间隙大小和嘶哑程度有显著改善。其他测试指标改善甚微。声带瘢痕形成患者术前和术后的嗓音功能较差，术后嗓音改善不大。声带弓状变形或瘢痕形成病例中I型甲状成形术的效果不如单侧声带麻痹病例。
