抄録

Three-dimensional (3D) CT endoscopy was applied to assess thyroplasty type I for two patients with recurrent laryngeal nerve (RLN) palsy. CT endoscopic images of these patients showed atrophy and flaccid tag of the vocal fold and expansion of the ventricle on the affected side threedimensionally. Increased thickness was shown post operatively. Furthermore, coronal MPR (multiplanar reconstruction) images clearly delineated position of the implanted silicone block in relation to the vocal fold. Thus, 3D CT endoscopic images could provide useful morphological information regarding RLN palsy pre-and post-operatively. In addition to conventional endoscopic and X-ray tomographic examinations.
