目的：腭裂儿童中耳炎的发病率升高，可能与听管和腭肌的病理有关。在本研究中，对双侧腭裂足月胎儿的头部进行了连续切片，并通过计算机辅助三维重建研究了听管和腭肌的解剖结构。 结果：结果显示听管的走向接近水平。腭帆张肌两侧均有骨附着。提腭帆肌也表现出异常走向。结论：这种异常走向可能导致收缩时听管阻塞。这些病理结果可能解释了腭裂儿童中耳炎的发生率较高的原因。
Objective: There is an increased incidence of otitis media in children with cleft palate, which may be related to the pathology of the auditory tube and palatal muscles. In the present study, the head of a human on term born fetus with bilateral palatal cleft was serially sectioned and the anatomy of the auditory tube and palatal muscles were studied by computer-aided three-dimensional reconstruction.Results: The results showed a nearly horizontal course of the auditory tube. The tensor veli palatini muscle had a bony attachment on either side. The levator veli palatini muscle also showed an abnormal course.Conclusions: This abnormal course may result in obstruction of the auditory tube during contraction. These pathological findings may explain the higher frequency of otitis media in children with cleft palate.
