Histologic sections from nine temporal bones with eustachian tubes (ETs) attached were analyzed with a computer-aided three-dimensional reconstruction method to determine the curvature and tilt of the ET and the anatomic relationships between the medial lamina of the ET cartilage, the levator veli palatini muscle (LVPM), and Rosenmüller's fossa. It was found that the ET is convex superomedially and is tilted medially. The LVPM is located inferolateral to the inferior margin of the medial lamina of the anterior ET cartilage. The LVPM is inferior to the medial lamina of the posterior ET cartilage. These findings suggest that the LVPM opens the anterior cartilaginous portion of the ET by rotating the medial lamina with increased dimension of the muscle body when it contracts. Rosenmüller's fossa extends along the ET with rich lymphoid tissues as far as approximately one half the total length of the ET and very close to the skull base.
对九块附有咽鼓管（ET）的颞骨组织切片采用计算机辅助三维重建方法进行分析，以确定ET的曲率和倾斜度以及ET软骨内侧板、腭帆提肌（LVPM）和咽隐窝之间的解剖关系。结果发现，ET在超级内侧呈凸形且向内倾斜。LVPM位于前ET软骨内侧板下缘的外下方。LVPM位于后ET软骨内侧板的下方。这些发现表明，LVPM在收缩时通过旋转内侧板并增加肌肉体尺寸来打开ET的前软骨部分。咽隐窝沿着ET延伸，有丰富的淋巴组织，长度约为ET总长度的一半，且非常靠近颅底。
