We designed a computerized tomography (CT)-based silastic implant preparation method that enabled custom fit to the individual size of the patient's larynx for medialization laryngoplasty.
Three women with unilateral vocal cord paralysis underwent type I thyroplasty operation. The individual size of the patient's larynx was determined by preoperative measurements on CT scan and the implant was prepared accordingly. The implant was then inserted through a rectangular window at the level of vocal cords which had been outlined according to CT findings.
Three patients, who were age 41, 25, and 37 years, underwent medialization laryngoplasty by this technique. They were followed up for 37, 16, and 4 months, respectively. There was not any rejection reaction, and satisfactory functional results with 10, 7, and 9 seconds of phonation duration have been achieved, respectively.
In this technique, the desired medialization of the paralyzed vocal cord was accomplished by the first insertion of the implant. Thus, the duration of the operation and the vocal cord edema aroused by manipulation of the inner perichondrium and internal laryngeal structures were reduced.
我们设计了一种基于计算机断层扫描（CT）的硅橡胶植入物制备方法，该方法能够根据患者喉部的个体大小进行定制，用于喉内移成形术。
3例单侧声带麻痹的女性患者接受了I型甲状成形术。通过术前CT扫描测量确定患者喉部的个体大小，并据此制备植入物。然后将植入物通过根据CT结果勾勒出的声带水平的矩形窗口插入。
3例患者年龄分别为41岁、25岁和37岁，采用该技术进行了喉内移成形术。她们分别接受了37个月、16个月和4个月的随访。未出现任何排斥反应，分别获得了10秒、7秒和9秒的发声时长，功能效果良好。
在该技术中，通过首次植入植入物实现了麻痹声带所需的内移。因此，缩短了手术时间，并减少了因操作甲状软骨内膜和喉内部结构而引起的声带水肿。
