目的:探讨喉癌行全喉切除术后的CT表现及其随访价值。材料和方法:回顾性分析经手术证实的43例喉癌行全喉切除术后的CT表现。结果:术后CT示整喉缺如,完整的舌骨或舌骨碎片,气管造瘘口壁薄、光滑、规则,甲状腺对称或不对称,新建的咽腔由舌底至颈段食管连接成圆形、卵圆形或塌陷状软组织管,食管、气管旁血管间隙模糊不清;其中12例术区见复发灶。结论:CT能观察全喉切除术后影像表现并判断有无术后复发。
Objective: To investigate the CT findings of laryngeal carcinoma after total laryngectomy and its follow-up value. Materials and Methods: A retrospective analysis of 43 cases of laryngeal carcinoma confirmed by surgery after total laryngectomy CT findings. Results: Postoperative CT showed incomplete throat, complete hyoid or hyoid fragments, tracheostomy fossa wall thin, smooth, regular, thyroid symmetry or asymmetry, the new pharyngeal cavity from the tongue to the cervical esophagus connected Round, oval or collapsed soft tissue tube, esophageal, tracheal vascular gap fuzzy; of which 12 cases of surgical area see recurrence.
