Longitudinal voice quality changes following Isshiki thyroplasty type I were investigated in a group of 13 patients exhibiting unilateral vocal fold paralysis. Thyroplasty type I medializes the paralyzed fold by using a Silastic implant for external lateral compression of the abducted fold. No perioperative complications were experienced. We observed significantly higher voice fundamental frequency, significantly louder voice intensity, and significantly longer maximum phonation time, both immediately following phonosurgery and up to 3 months postoperatively. Surgical refinements of thyroplasty type I are described.
在一组13例单侧声带麻痹患者中，研究了Ⅰ型甲状软骨成形术后纵向的嗓音质量变化。Ⅰ型甲状软骨成形术通过使用硅橡胶植入物对外展的声带进行外侧挤压，使麻痹的声带内移。未出现围手术期并发症。我们观察到，在嗓音手术后即刻以及术后长达3个月的时间里，嗓音的基频显著提高，嗓音强度显著增大，最长发声时间显著延长。文中还描述了Ⅰ型甲状软骨成形术的手术改进方法。
