In ten patients with marked protrusion of the false vocal fold, the underlying structures were examined by computed tomography. The computed tomographic scan at the level of the false vocal fold consistently demonstrated a marked concavity of the thyroid ala on the side of the false-fold protrusion. The angle between the thyroid alae was significantly smaller in these patients than in normal controls. A combination of the above two deformities was considered to be responsible for the protrusion of the false vocal fold. Since all the patients were aged men, the deformity of the thyroid cartilage was presumed to be acquired, and related in some way to the aging process of the cartilage.
对10例假声带明显突出的患者，通过计算机断层扫描检查其深部结构。在假声带水平的计算机断层扫描始终显示，假声带突出侧的甲状腺翼板有明显凹陷。这些患者甲状腺翼板之间的角度明显小于正常对照组。上述两种畸形的组合被认为是导致假声带突出的原因。由于所有患者均为老年男性，推测甲状腺软骨畸形是后天获得的，并且在某种程度上与软骨的老化过程有关。
