The elevation of the pharynx and larynx at swallowing in 10 patients with a defective relaxation of the cricopharyngeal muscle, was compared with that in 10 normals. The pharynx and larynx moved higher among patients with a defective relaxation of the cricopharyngeal muscle. Therefore, it can be concluded that a defective relaxation of the cricopharyngeal muscle at swallowing has no relationship to a defective pharyngo-laryngeal elevation.
对10例环咽肌松弛功能不全患者吞咽时咽和喉的抬高情况与10例正常人进行了比较。环咽肌松弛功能不全患者的咽和喉抬高幅度更大。因此，可以得出结论，吞咽时环咽肌松弛功能不全与咽-喉抬高功能不全无关。
