To evaluate the clinical applications of computer tomography virtual laryngoscopy (CTVL) in laryngeal carcinoma.
34 cases of laryngeal carcinomas and 5 cases of normal larynx were scanned by spiral CT and analyzed by computers. The virtual endoscopy findings of all patients were compared with those of fiber optical laryngoscopy and surgical findings. All the carcinomas were pathologically proved.
The visualization of normal anatomical structure in larynx on CTVL is the same as that of fiber optic laryngoscopy. Tumor local extension showed in CT virtual endoscopy is superior to that of fiber optic laryngoscopy. Images of early laryngeal carcinomas showed in CT virtual endoscopy is not so good as those of fiber optic laryngoscopy.
CT virtual laryngoscopy is a good complement to fiber optic laryngoscopy.
评估计算机断层扫描虚拟喉镜（CTVL）在喉癌中的临床应用。
对34例喉癌患者和5例正常喉部进行螺旋CT扫描并经计算机分析。将所有患者的虚拟内镜检查结果与纤维喉镜检查结果及手术所见进行比较。所有癌症均经病理证实。
CTVL上喉部正常解剖结构的可视化与纤维喉镜相同。CT虚拟内镜显示的肿瘤局部扩展情况优于纤维喉镜。CT虚拟内镜显示的早期喉癌图像不如纤维喉镜清晰。
CT虚拟喉镜是纤维喉镜的良好补充。
