To report the volumetric measures of the paralyzed vocal fold in patients undergoing injection laryngoplasty.
All the medical records of patients with unilateral vocal fold paralysis who had high resolution computerized tomography scan of the neck and chest prior to injection laryngoplasty between October 2015 and May 2018 were included. Volumetric evaluation of the vocal folds was performed by measuring the vocal fold height using coronal images and the vocal fold length and width using axial images.
A total of 21 patients divided into 13 males and 8 females were identified. The mean age was 56.66 20.94 years. The mean volume of the paralyzed vocal fold was significantly smaller than that of the non-paralyzed vocal fold ( < .05). Similarly, the mean length and height of the paralyzed vocal folds were smaller than those of the non-paralyzed vocal folds ( < .05).
Volumetric measurements of the paralyzed vocal fold in comparison to the normal vocal fold in a group of 21 patients with unilateral vocal fold paralysis shows the presence of significant difference between the normal and affected site, and the presence of large inter-subject variation. Information on the volume difference between the two vocal folds may be used to better estimate the amount that needs to be injected in medialization procedures.
报告行注射式喉成形术患者患侧声带的体积测量值。
回顾性分析 2015 年 10 月至 2018 年 5 月期间因单侧声带麻痹行颈部和胸部高分辨率计算机断层扫描（computed tomography，CT）检查并拟行注射式喉成形术的患者的所有病历资料。通过冠状位图像测量声带高度，通过轴位图像测量声带长度和宽度，对声带进行体积评估。
共纳入 21 例患者，男 13 例，女 8 例，平均年龄 56.66±20.94 岁。患侧声带的平均体积明显小于健侧（<0.05）。同样，患侧声带的平均长度和高度也小于健侧（<0.05）。
与单侧声带麻痹患者的健侧声带相比，21 例患者患侧声带的体积测量值显示正常和患病部位之间存在显著差异，且个体间差异较大。关于两侧声带体积差异的信息可用于更好地估计声带内移术中需要注射的剂量。
