Nineteen patients with carcinoma of the larynges and 1 patient with carcinoma of the pyriform sinus were studied by comparing preoperative CT scannings with corresponding postoperative pathological findings obtained by serial sectioning of the laryngeal specimens. The results indicated that CT could clearly show the mucosa and deep tissues of the larynx including paraglottic space, preepiglottic space and subglottic region. The determination of cartilage invasion larger than 5mm was very accurate and reliable. It also significantly enhanced preoperative T-staging accuracy of medium and large laryngeal carcinomas and provided an important basis for selection of laryngeal conservative surgery. Nevertheless, CT scanning of the larynx has certain limitations.
对19例喉癌患者和1例梨状窝癌患者进行了研究，通过将术前CT扫描结果与喉标本连续切片获得的相应术后病理结果进行比较。结果表明，CT能够清晰显示喉部的黏膜和深部组织，包括声门旁间隙、会厌前间隙和声门下区。对大于5mm的软骨侵犯的判定非常准确可靠。它还显著提高了中大型喉癌术前T分期的准确性，为喉保留手术的选择提供了重要依据。然而，喉部CT扫描有一定的局限性。
