目的：探讨螺旋ＣＴ仿真内窥镜在喉部的临床应用价值。方法：共１７例，其中７例为正常喉，９例为喉癌，１例为喉乳头状瘤；行喉部螺旋ＣＴ扫描后在工作站经软件处理，得到喉部仿真内窥镜图像，并与纤维喉镜进行对照研究。结果：喉部螺旋ＣＴ仿真内窥镜检查，自头端入路可见７例正常喉能清楚显示喉部解剖形态，９例喉癌和１例乳头状瘤能清楚显示肿瘤位置、形态、大小范围，与纤维喉镜检查一致。自足端入路，可见１例声门下软组织块影，２例声门下粘膜增厚，２例气管内结节影；而纤维喉镜却难以观察到。结论：螺旋ＣＴ仿真内窥镜可以清楚观察到喉腔内表面结构以及病变的位置、形态、大小范围；而足端入路对声门下结构的观察是纤维喉镜难以做到的。它是纤维喉镜的重要补充方法。
Objective: To investigate the clinical value of spiral CT virtual endoscopy in the throat. Methods: A total of 17 cases, of which 7 cases of normal laryngeal, 9 cases of laryngeal cancer, 1 case of laryngeal papilloma; throat CT scan after the workstation software processing, laryngeal simulation endoscopic images and Contrast study with fiber laryngoscope. Results: The laryngeal spiral computed tomography endoscopy showed that the laryngeal anatomy was clearly seen in 7 cases of normal larynx. The laryngeal carcinoma and 1 case of papilloma clearly showed tumor location, morphology, size range , Consistent with fiberoptic examination. Self-sufficient approach, we can see 1 case of subglottic soft tissue block shadow, 2 cases of subglottic mucosa thickening, 2 cases of tracheal nodules; and fiber laryngoscopy is difficult to observe. Conclusion: Spiral CT virtual endoscopy can clearly observe the surface structure of the larynx and the location, shape and size of the lesion. The observation of the subglottic structure by the foot approach is difficult to achieve by the fiber laryngoscope. It is an important supplement to fiber laryngoscopes.
