摘　　要：目的观察不同病程的胆脂瘤型中耳炎患者咽鼓管上隐窝的大小,探讨咽鼓管上隐窝的形态学改变与病程的关系。方法采用颞骨薄层CT摄片方法,对胆脂瘤型中耳炎患者的咽鼓管上隐窝的大小进行测量。结果患耳的咽鼓管上隐窝形态较正常耳小,不同病程的胆脂瘤型中耳炎患者患耳咽鼓管上隐窝形态(前后径、垂直径与高度)改变无显著差异(t检验,P>0.05)。结论患耳咽鼓管上隐窝与正常耳相比,其较小的形态可能在疾病发生前已经存在,而非疾病的发展过程中形成。提示咽鼓管上隐窝的形态可影响胆脂瘤型中耳炎的形成。在胆脂瘤型中耳炎的手术治疗中,尤其是完壁式鼓室成形术中,应在术中扩大咽鼓管上隐窝,改善中耳气体引流通道,以期减少术后复发。Objective To investigate the relation between the morphological changes of supratubal recess and the course of eholesteatoma. Methods Using high resolution CT to measure the supratubal recess of the cholesteatoma ears. Results the size of the supratubal recess showed no significant difference during cholesteatoma ears with different courses （P〉0.05）, there was no relationship between the size of the supratubal recess and the course of cholesteatoma. Conclusion The supratubal recess of the cholesteatoma is smaller than the normal ears. It happened before the development of cholesteatoma. The morphological changes of supratubal recess may affect the formation of cholesteatoma. The enlargement of supratubal recess during the operation of canal wall up technique may cut down recurrence rate of cholesteatoma.
