摘要
目的：评估下咽癌侵犯喉结构（ 包括声门旁间隙、会厌前间隙、杓会厌襞、甲状软骨、环状软骨及杓状软骨） 的 Ｃ Ｔ 诊断价值。方法：对２１ 例下咽癌的 Ｃ Ｔ 扫描与病理检查结果进行对比分析，以确定其准确性，并同喉镜检查＋ 喉侧位片进行比较。结果： Ｃ Ｔ 对于判断下咽癌侵犯喉结构的准确率远较喉镜检查＋ 喉侧位片高，假阳性及假阴性结果较少，优势明显。结论：应将 Ｃ Ｔ 扫描纳入下咽癌常规临床检查。
Objective:To study the CT evaluation of laryngeal involement (inclues:laryngeal cartilage,space and aryepiglottic fold) of hypopharyngeal carcinoma(HPC) Methods:21 cases with HPC were studied,CT diagnosis and postoperative pathologic study were compared Results:CT diagnosis is more accurate than that of mirror examination or direct laryngoscopy and lateral views of larynx Conclusions: CT scanning should be rountinly conducted in order to improve the diagnosis rate in determing the laryngeal involvement of HPC
