作者报告本人手术之胆脂瘤患者109例,非胆脂瘤性中耳炎160例(单纯型122例,粘连性中耳炎36例,其他2例)。根据观察结果,认为胆脂瘤与炎症类型不同,其骨质破坏方式区别甚大。鼓膜内侧炎性肉芽是胆脂瘤扩展的重要因素。由于细胞(巨噬细胞、成纤维细胞、破骨细胞)的活动,炎症过程(炎性肉芽生化反应)得以在听骨表面及其内部血管通道中发展。松弛部胆脂瘤:胆脂瘤上皮多由槌骨及砧骨外侧向后扩展。在病程中,全不累及听骨链者21%,槌骨破坏者49%,砧骨78%,镫骨22%。病变开始多见槌骨头、砧骨体和短脚外侧病变。
The authors reported 109 cases of cholesteatoma who underwent surgery, 160 cases of non cholesteatoma otitis media (simple type 122 cases, 36 cases of otitis media conglutination, the other 2 cases). According to the observation, it is considered that cholesteatoma differs from the type of inflammation in that there is a great difference in the way of bone destruction. Inflammatory granulation inside the tympanic membrane is an important factor in the expansion of cholesteatoma. Due to the activity of cells (macrophages, fibroblasts, osteoclasts), inflammatory processes (inflammatory granulation biochemical reactions) develop in the ossicular surface and its internal vascular access. Relaxed cholesteatoma: cholesteatoma mostly by the outer mandibular and incus expansion. In the course of the disease, 21% were not involved in the ossicular chain, 49% of the mallet, 78% of the incus, and 22% of the stapes. Lesions began more common hammerhead, anvil body and lateral short foot disease.
