声门功能不全是一种常见的喉部疾病，导致吞咽和发声功能障碍。合成的声音的特征是微弱和喘息，音调范围有限。目前，声门关闭不全的外科治疗方法主要有中性化甲状腺成形术和环状软骨内收术。然而，很少有研究评估I型甲状腺成形术和环状软骨内收手术对语音客观测量的影响。在这项研究中，59名声门功能不全的患者接受了I型甲状腺成形术或颧骨内收术。手术前后测量声学指标(抖动、微扰和谐噪比)和空气动力学指标(气流、声门下压力和声门阻力)，不同术式的声学指标和空气动力学指标差异无统计学意义。然而，在手术前后观察到了显著的经喉气流的影响。此外，传统手术指征与非传统手术指征之间的差异无统计学意义。因既往喉部手术(如声带剥离)而出现声门功能不全的患者，在甲状腺成形术或内收术后声学或空气动力学测量方面没有统计学上的显著改善。
Glottal incompetence is a common laryngeal disorder causing impaired swallowing and phonation. The resultant voice has been characterized as weak and breathy with a restricted pitch range. Currently, medialization thyroplasty and arytenoid adduction are two of the surgical treatments for patients with glottal incompetence. However, few studies have evaluated the changes in objective measures of speech with type I thyroplasty and arytenoid adduction. In this study, 59 patients with glottal incompetence underwent either type I thyroplasty or arytenoid adduction. Acoustic (jitter, shimmer, and harmonics-to-noise ratio) and aerodynamic (airflow, subglottic pressure, and glottal resistance) measures were obtained both pre- and postoperatively, No significant differences were found among acoustic or aerodynamic measures for operation type. However, a significant pre/postsurgery effect was observed for translaryngeal airflow. In addition, no significant differences were found among the measures for patients with traditional compared with nontraditional operative indications. Patients who developed glottal insufficiency due to previous laryngeal surgery (e.g., vocal fold stripping) demonstrated no statistically significant improvement in acoustic or aerodynamic measures following thyroplasty or arytenoid adduction.
