Computed tomography (CT) was used in 33 patients to evaluate possible extralaryngeal causes of vocal cord paralysis (22 left, 11 right). Neoplasm in the lower neck or upper mediastinum (lung, esophagus, thyroid, breast, lymphoma) was found to be the predominant cause (27/33). A negative CT examination correlated with a neuropathic (e.g., diabetes) or idiopathic etiology. CT proved useful in demonstrating or excluding abnormalities in areas that are difficult to evaluate by physical examination or conventional radiography, particularly the aortopulmonary window. The normal anatomy and pathologic masses involving the recurrent laryngeal nerve are illustrated.
对33例患者进行了计算机断层扫描（CT），以评估声带麻痹可能的喉外病因（左侧22例，右侧11例）。发现下颈部或上纵隔的肿瘤（肺、食管、甲状腺、乳腺、淋巴瘤）是主要病因（27/33）。CT检查结果为阴性与神经病变（如糖尿病）或特发性病因相关。CT被证明有助于显示或排除体格检查或传统X线摄影难以评估的区域的异常，尤其是主动脉肺动脉窗。文中展示了喉返神经的正常解剖结构和病理肿块。
