Computed tomography scans of the larynx were obtained during quiet breathing and during phonation in 10 volunteers having no neck or larynx abnormalities. The subglottic and glottic laryngeal cavity and soft tissues showed symmetry from side to side. At the supraglottic level, the pliable aryepiglottic folds and pyriform sinuses appeared moderately asymmetric and variable during quiet breathing. Phonation made them more symmetric. Phonation also allowed accurate determination of vocal cord function. The laryngeal cartilages were symmetric in their degree of calcification and had clearly visible centers of dense calcification. Computed tomography is a highly precise method for demonstrating the structures of the larynx.
对10名无颈部或喉部异常的志愿者在安静呼吸和发声时进行了喉部计算机断层扫描。声门下和声门喉部腔隙及软组织左右对称。在声门上水平，柔软的杓会厌襞和梨状窦在安静呼吸时表现为中度不对称且形态各异。发声使其更加对称。发声还能准确测定声带功能。喉软骨的钙化程度对称，有清晰可见的致密钙化中心。计算机断层扫描是显示喉部结构的一种高精度方法。
