CT仿真喉镜的临床应用

目的 探讨ＣＴ新技术仿真内窥镜成像在喉科的临床应用价值。方法 对４名健康者、９例喉癌、１例喉癌术后复发气道狭窄、１例喉内外弥漫纤维瘤样增生、１例双侧声带息肉患者行螺旋ＣＴ扫描后经软件处理获得仿真喉镜影像，并与纤维喉镜、手术所见对照分析。结果 ＣＴ仿真内窥镜显示喉内正常解剖结构与纤维喉镜所见一致；显示喉内病变的位置、范围与纤维喉镜所见类型，还可从足端入路观察到喉镜所看不到的狭窄远端和声门下区情况。绪

Application of CT virtual endoscopy in larynx]

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.
