Cricopharyngeal dysfunction is a relatively uncommon disorder that is misunderstood by many physicians. Cricopharyngeal dysmotility is thought to indicate abnormal function in the upper esophageal or cricopharyngeal sphincter, the etiology of which is related to uncoordinated pharyngeal swallowing, achalasia, or a combination of these factors. Unfortunately, standard diagnostic tests do not consistently show that the cricopharyngeal sphincter malfunctions; so cricopharyngeal myotomy has been suggested as a diagnostic and therapeutic tool in the treatment of dysmotility. The current report reviews trends in the diagnosis and treatment of cricopharyngeal myotomy, including the results of cricopharyngeal myotomy using the potassium-titanyl-phosphate (KTP) laser. A transmucosal cricopharyngeal myotomy with the KTP laser may be a viable alternative for patients with cricopharyngeal dysmotility compared with conventional techniques.
环咽肌功能障碍是一种相对罕见的疾病，许多医生对其存在误解。环咽肌运动障碍被认为表明食管上段或环咽肌括约肌功能异常，其病因与咽部吞咽不协调、贲门失弛缓症或这些因素的组合有关。不幸的是，标准诊断测试并不能始终表明环咽肌括约肌存在功能障碍；因此，环咽肌切开术被建议作为治疗运动障碍的一种诊断和治疗工具。本报告回顾了环咽肌切开术的诊断和治疗趋势，包括使用磷酸钛氧钾（KTP）激光进行环咽肌切开术的结果。与传统技术相比，用KTP激光进行经粘膜环咽肌切开术可能是环咽肌运动障碍患者的一种可行替代方法。
