OBJECTIVE
To evaluate the clinical application of CT virtual endoscopy in larynx.
METHODS
The virtual endoscopy images were compared with that of actual laryngoscopy in 16 patients(4 normal larynx, 9 laryngeal carcinomas, 1 bilateral glottic polyps, one laryngeal fibrous hyperplasis and 1 airway striction caused by infiltration of the laryngeal carcinoma after laryngectomy). All the lesions were pathologically proved.
RESULTS
CT virtual endoscopy showed the normal anatomical structure of larynx as actual laryngoscopy. The location and extension of the lesions of larynx showed in CT virtual endoscopy agreed with that of actual laryngoscopy. In addition, CT virtual laryngoscopy revealed the structure of subglottic region and distal portion of strictured airway from feet to head, which were not available in actual laryngoscopy.
CONCLUSION
CT virtual laryngoscopy is a good complemental method of fiber optic laryngoscopy.
目的
评估CT虚拟喉镜在喉部的临床应用。
方法
对16例患者（4例正常喉部、9例喉癌、1例双侧声门息肉、1例喉纤维组织增生、1例喉癌喉切除术后浸润致气道狭窄）的虚拟喉镜图像与实际喉镜图像进行比较。所有病变均经病理证实。
结果
CT虚拟喉镜显示喉部正常解剖结构与实际喉镜相同。CT虚拟喉镜显示的喉部病变部位及范围与实际喉镜一致。此外，CT虚拟喉镜能从足部到头部显示声门下区及狭窄气道远端的结构，而实际喉镜无法做到。
结论
CT虚拟喉镜是纤维喉镜的良好补充方法。
