An experimental study of the modus operandi of tensor and levator palati muscles over the Eustachian tube was conducted in two dogs. The tensor palati muscle is divisible into four functional units: (1) anterior part, vertical fibers; (2) middle part, oblique fibers; (3) posterior part, horizontal fibers; and (4) posterior-most part, osseous origin. Though the levator palati passively fixes the medial lamina and narrows the pharyngeal ostium, it dilates the lumen of the isthmus by two mechanisms: (1) rectification of the isthmus "kink" by bringing the cartilaginous and osseous segments into a stright line; and (2) pushing away the surrounding soft tissue pressure that is being exerted over the medial wall of the tube (not protected by cartilage). The peculiar absence of the medial cartilaginous lamina near the isthmus is attributed to the following: (1) freedom of movement of cartilaginous tube; (2) better anchorage of tubal cartilage passively by levator palati; (3) "kinking" of canal; and (4) compression of the lumen.
在两只狗身上进行了关于腭帆张肌和腭帆提肌作用于咽鼓管的操作方法的实验研究。腭帆张肌可分为四个功能单元：（1）前部，垂直纤维；（2）中部，斜纤维；（3）后部，水平纤维；（4）最后部，骨性起点。虽然腭帆提肌被动固定内侧板并使咽口变窄，但它通过两种机制扩张峡部管腔：（1）通过使软骨段和骨段成一直线来矫正峡部“扭结”；（2）推开施加在管壁内侧（未被软骨保护）的周围软组织压力。峡部附近内侧软骨板的特殊缺失归因于以下几点：（1）软骨管的活动自由度；（2）腭帆提肌被动更好地固定咽鼓管软骨；（3）管腔“扭结”；（4）管腔受压。
