Cricopharyngeal myotomy is an effective procedure for the treatment of swallowing disorders due to dysfunction of the upper esophageal sphincter and pharyngeal musculature. Eight patients with documented pharyngeal and sphincteric dysfunction have undergone myotomies with significant improvement in swallowing associated with restoration of oral feeding without aspiration in 5, while 3 patients have not improved. The preoperative work-up and evaluation is discussed as well as criteria that may identify those patients most likely to benefit from this treatment.
环咽肌切开术是治疗因食管上括约肌和咽部肌肉功能障碍引起的吞咽障碍的有效方法。8例有记录的咽部和括约肌功能障碍患者接受了肌切开术，其中5例吞咽功能显著改善，恢复经口进食且无误吸，而3例患者未见改善。本文讨论了术前检查和评估，以及可能识别出最有可能从该治疗中获益的患者的标准。
