The hypopharyngeal anatomy of 20 post-laryngectomy patients was studied both with endoscopy and radiological contrast medium examination. The pharynx was found to be essentially a featureless tube with mucosal rugosities running along its axis. No correlation was found between the endoscopic and radiological appearance of the pseudoepiglottis, or between its presence and post-operative complications or the acquisition of oesophageal speech. A low incidence of post-operative dysphagia was noted. The RPS ratio for normal patients was calculated.
对20例喉切除术后患者的下咽解剖结构进行了内镜检查和放射学造影剂检查。发现下咽基本上是一个无特征的管道，其黏膜皱襞沿轴线延伸。在假会厌的内镜和放射学表现之间，或其存在与术后并发症或食管语音获得之间未发现相关性。注意到术后吞咽困难的发生率较低。计算了正常患者的RPS比率。
