Résumé

Three-dimensional CT scan imaging obtained by using helicoidal CT scan provides the basis for an endoscopic exam said to be virtual since no invasive procedure is actually performed. Compared to optical endoscopy this easily accessible exam offers additional information especially for the analysis of the infraglottic and tracheal areas, which are two anatomically rigid segments. This property facilitates their three-dimensional reconstruction. Our study encompassed 6 patients presenting with a stenosis of the laryngotracheal tract. In 5 of them it was possible to correlate optical and virtual endoscopic imaging. Coupling both exams significantly improved the diagnostic investigation and facilitated the management of the disease. However, the real contribution of virtual endoscopy to the exploration of tumoral conditions still remains to be determined given the low degree of tissue resolution. As a consequence parietal and extraparietal lesional spreading is more accurately assessed by axial scan imaging.
