Eight normal larynges from autopsy cases were CT scanned and 1.5 mm contiguous slices in the cricoarytenoid joint region were taken. The larynges were then sectioned and stained for histological correlation. Different degrees of calcification, ossification and bone marrow cavitation of the cricoid and arytenoid cartilages were observed. This explained the variety of presentations of these structures on CT films. For example, the cricoarytenoid articular interspace was not always visible due to the saddle-shaped configuration of the joint superimposing cartilages on axial views. Features of normal CA joints on CT scan are discussed.
对8例尸检病例的正常喉部进行CT扫描，并在环状杓状软骨关节区域获取1.5毫米连续切片。然后将喉部切片并进行染色以进行组织学对照。观察到环状软骨和杓状软骨有不同程度的钙化、骨化和骨髓腔形成。这解释了这些结构在CT片上的多种表现。例如，由于关节的鞍状结构在轴位视图上软骨相互重叠，环状杓状软骨关节间隙并不总是可见。本文讨论了CT扫描上正常环状杓状软骨关节的特征。
