从３１例胆脂瘤型中耳炎患者中取出４２块听骨（包括２１块槌骨及２１块砧骨）。在手术显微镜下观察有８块槌骨及１８块砧骨受到破坏。４１例听骨有组织学改变。７例听骨细胞角蛋白染色呈阳性表达。在组织学方面证实了胆脂瘤型中耳炎听骨具有病变残留，而且听骨大体破坏情况与组织学改变的严重程度并不相关。认为利用手术显微镜对胆脂瘤型中耳炎听骨的再利用可行性进行评估并不可靠，胆脂瘤型中耳炎听骨不宜用于听骨链重建术。
Twenty-two ossicles (including 21 mallet and 21 incus) were removed from 31 patients with cholesteatoma otitis media. Observed under a surgical microscope with eight mallet and 18 incus damaged. 41 cases of ossicular histological changes. Seven cases were positive for keratin staining. Histologically confirmed cholesteatoma otitis media with residual lesions, and gross dehiscence and severity of histological changes are not related. That the use of surgical microscopy of cholesteatoma otitis media to evaluate the feasibility of reusing the bone is not reliable, cholesteatoma otitis media is not suitable for use in ossicular reconstruction.
