摘　　要：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。Purpose To explore the postoperative CT appearance of the larynx after total laryogectomy for carcinomas and value of follow-up CT scans.Materials and Methods 43 cases of total laryngectomy for carcinomas confirmed by surgery and pathology were analyzed retrospectively.Results The appearances of postoperative CT scans were as follows：absence of the whole larynx;the complete hyoid bone or hyoid bone fragments ;regular,thin and smooth tracheal stoma wall;symmetrical or asymmetrical thyroid lobes.Reconstructed pharyngeal cavity was round,ovoid or collapsed that ranged from the base of the tongue to the cervical esophagus.Vascular space around esophagus and trachea was blurred.Recurrent tumors were found in the operative regions of the twelve patients in this group.Conclusion CT scans can provide reliable images of the larynx after total laryngectomy for carcinomas and can clearly depict recurrent tumors.
