摘　　要：目的分析食管癌术后声带麻痹的CT表现及其与纵隔淋巴结转移的关系，提高对其影像学表现的认识。方法回顾性分析临床诊断为食管癌术后并发声带麻痹的40例患者的CT资料。结果声带麻痹CT表现：患侧杓会厌皱襞增厚、向前内侧移位，同侧梨状隐窝扩大34例（85％）；患侧声带萎缩外展，同侧喉室扩大31例（77．5％）；患侧杓状软骨向前内侧移位16例（40Voo）等。38例（95％）患者发现纵隔淋巴结转移，4例（10％）患者发现吻合口复发。结论CT检查为声带麻痹的确诊提供了重要依据，而且有助于明确引起声带麻痹的原因。Objective To analyse CT performances of vocal cord paralysis after resection of esophageal carcinoma and its relation- ship with mediastinal lymph node metastasis, in order to improve the recognition of the imaging manifestations of it. Methods 40 cases of vocal cord paralysis clinically after resection of esophageal carcinoma confirmed were retrospectively analysed. Results CT findings of vocal cord paralysis included： thickening and anteromedial displacement of the ipsilateral aryepiglottic folds, ipsilateral piriform sinus dilatation in 34 cases （85%） ;vocal cord atrophy and lateral displacement,ipsilateral laryngeal ventricle dilatation in 31 cases（77.5%）; anteromedial displacement of the ipsilateral arytenoid cartilage in 16 cases（40%） etc. Mediastinal lymph node me- tastasis in 38 cases（95 %） and anastomotic recurrence of esophageal carcinoma in 4 cases（10%）. Conclusion CT scan is helpful in diagnosirxg vocal cord paralysis and its etiology.
