对听小骨破坏尤其是砧骨均以鼓室窦型胆脂瘤及鼓膜紧张部型胆鳆瘤病耳最严重。

Destruction of the incus was by far the most common ossicular defect in all cholesteatoma ears .

有72%病例可见完整的听小骨链，并且通常能在外科手术中予以保存。

An intact ossicular chain was found in72 % of the cases and could often be preserved at surgery .

方法：通过光镜观察8例胆脂瘤破坏的听小骨和2例正常听小骨的形态学表现。

Method : The morphology of auditory ossicles in 8 cholesteatoma samples and 2 normal samples were observed with light microscope .

但缺少针刺前后，三块听小骨的位置变化的客观依据。

But lack before and after acupuncture , three pieces of listen to the little bone position change the objective basis .
