A patient with complete esophageal obstruction from cricopharyngeal achalasia in whom adequate cricopharyngeal myotomy failed to alleviate the dysphagia is described. The importance of pre-operative radiological evaluation of patients with neurologically related dysphagia is discussed, specifically, the degree of obstruction, range of tongue movement, and presence of aspiration. These factors have a predictive value in assessing the benefits of planned cricopharyngeal myotomy.
本文描述了一例因环咽肌失弛缓症导致完全性食管梗阻的患者，其接受了充分的环咽肌切开术，但吞咽困难仍未缓解。文中讨论了对神经源性吞咽困难患者进行术前影像学评估的重要性，特别是梗阻程度、舌运动范围和误吸情况。这些因素在评估计划性环咽肌切开术的获益方面具有预测价值。
