Among thyroplasties, type I is the most frequently used for medialization of the vocal cord. Follow-up study on patients indicated that reversion of voice can occur after operation. Revision was done in five cases with improvement of voice. On the basis of this experience, modifications were made in the technique of thyroplasty type I. They include 1) cutting the calcified cartilage with minimal intervention in the soft tissue, 2) fixation of the window with a silicone plug to enhance medialization, and 3) overmedialization of the vocal cord and definition of criteria for it that can be used during surgery.
在声带成形术中，I型是用于声带内移最常用的类型。对患者的随访研究表明，术后声音可能会恢复原状。对5例患者进行了修复，声音得到改善。基于这一经验，对I型声带成形术技术进行了改进。改进包括：1）在软组织干预最小的情况下切割钙化软骨；2）用硅胶塞固定窗口以增强内移效果；3）声带过度内移及其手术中可用标准的界定。
