The advent of newer generation high resolution computed tomography (CT) scanners has revolutionized diagnostic evaluation in head and neck cancer. Since the development of conservation surgical techniques for the larynx, a precise preoperative evaluation of the extent of laryngeal involvement by carcinoma has been of prime importance. No single diagnostic study now yields more information regarding the anatomic extent of tumor than high resolution CT scanning. This study was designed to evaluate the reliability of CT scanning in determining extent of disease at several laryngeal levels by comparing preoperative CT scans with corresponding postoperative pathology obtained by serially sectioning laryngeal specimens. We found very good correlation in the inferior larynx and good correlation in the superior larynx. Determination of cartilage invasion proved very difficult, and scanning was unreliable at all levels when severe postradiation reactions were present.
新一代高分辨率计算机断层扫描（CT）扫描仪的出现彻底改变了头颈癌的诊断评估。自从喉保留手术技术发展以来，对癌肿累及喉部范围进行精确的术前评估一直至关重要。目前，没有任何一项诊断研究能比高分辨率CT扫描提供更多关于肿瘤解剖范围的信息。本研究旨在通过将术前CT扫描与对喉部标本进行连续切片获得的相应术后病理结果进行比较，评估CT扫描在确定喉部几个层面疾病范围方面的可靠性。我们发现，CT扫描在下喉部的相关性非常好，在上喉部的相关性良好。确定软骨侵犯非常困难，当存在严重的放疗后反应时，各个层面的扫描都不可靠。
