In a study of 160 unselected patients with goitre, 116 (72.5%) had tracheal deviation and ninety-two (57.5%) had tracheal narrowing. Tracheal deviation to the right constituted 65% of the lateral deviations, but when thyroid malignancies only were considered, a disproportionately large number (ten of the thirteen cases) showed deviation to the left. Anterior deviation and irregular tracheal narrowing which were previously considered to be characteristic of thyroid malignancy are shown to be non-specific. Whereas irregular tracheal narrowing should still raise the suspicion of malignancy, a simple multinodular goitre may produce a similar appearance, resulting from variable degrees of pressure on the trachea by adjacent thyroid nodules of different sizes.
在一项对160例未经挑选的甲状腺肿患者的研究中，116例（72.5%）有气管移位，92例（57.5%）有气管狭窄。气管向右移位占侧方移位的65%，但仅考虑甲状腺恶性肿瘤时，向左移位的比例过高（13例中有10例）。先前认为是甲状腺恶性肿瘤特征的气管前移位和不规则气管狭窄被证明是非特异性的。虽然不规则气管狭窄仍应引起对恶性肿瘤的怀疑，但单纯的结节性甲状腺肿也可能产生类似表现，这是由不同大小的相邻甲状腺结节对气管的不同程度压迫所致。
