Dysphagia associated with the cricopharyngeus muscle (CPm) dysfunction negatively influences the quality of life. This high-pressure region must relax and the lumen must open for smooth food passage. The CP muscle is therefore a common target of chemodenervation with botulinum toxin (BTX). Here we presented a patient with severe left lateral medullary syndrome and non-relaxation of the CPm. We described how to localize the CPm in the transverse and longitudinal views under ultrasonography and offered a video demonstrating ultrasonography-guided BTX injection. Ultrasonography-guided CPm injection with BTX may serve as a reliable, rapid, and effective choice for treatment of cricopharyngeal dysphagia.
环咽肌（CPm）功能障碍相关的吞咽困难会降低生活质量。这个高压区域必须放松，管腔必须打开才能使食物顺利通过。因此，CP 肌肉是肉毒毒素（BTX）化学去神经支配的常见靶点。我们在此介绍了一例严重的左侧延髓外侧综合征患者，其 CPm 不松弛。我们描述了如何在超声下的横切和纵切面上定位 CPm，并提供了一个超声引导下 BTX 注射的视频。超声引导下 CPm 注射 BTX 可能是治疗环咽性吞咽困难的可靠、快速和有效的选择。
