Middle ear cholesteatoma is destructive to auditory ossicles and temporal bone, and treatment usually includes surgical removal of all epithelial content in the tympanomastoid cavity.

中耳胆脂瘤在临床上对於听小骨和颞骨具有相当的侵蚀性，而治疗上通常必须以手术清除中耳腔所有的上皮成份。

As for recurrence, the avoidance of a too-large postoperative tympanomastoid space, the establishment of a patent epi-mesotympanic route, and the preservation of adequate middle ear mucosa should be emphasized.

Methods CTVE of auditory ossicular chain was performed on GE HiSpeed CT/i with 1.0 mm slice thickness at pitch 1.0,bone algorithm,9.6 cm FOV,and 0.1 mm reconstruction interval in 10 normal subjects and 21 patients with middle ear diseases,14 of them were proved by operation.

使用HiSpeed CT/i扫描机，层厚1.0 mm、螺距1.0、骨算法、视野9.6 cm×9.6 cm、间隔0.1 mm重建，对10例正常中耳和21例临床怀疑中耳病变（14例手术）的患者进行CTVE成像。

The abnormality degrees of their external and middle ear were observed, the relationship between the auricle growing level, the bony fossa of external acoustic meatus, the hearing degree before operation and the abnormalities of middle ear were reviewed respectively.

统计各种外、中耳畸形情况，比较耳廓发育程度、颞骨相当于外耳道口处有无骨性小凹、术前听力损失程度与中耳畸形的关系，将术前的常规横断位 CT检查结果与术中所见进行对照。

Results:The lesion of cholesteatoma (8/17) appeared as mass shadows in tympanic sinusand and cavity with low denisty ring around, accompanied with obvious ossicles chain destruction.

结果：胆脂瘤8例表现为中耳腔内团块状影，周围低密度环包绕，听骨明显破坏及中耳窦腔扩大，骨缘硬化。4例肉芽肿多呈片状、条索状或网状，听骨破坏较轻。

Ordinary no destruction , the ossicular chain can be erosions and destruction , but more slight and no transitional .the major CT findings in simple chronic middle ear on 2 patients were soft tissue in middle ear cavity ,and 1 patient findings hydropneumo, the bone of tympanic cavity cirrhosis ,no destruction .

其它征象包括乙状窦、鼓室盖、水平半规管、面神经管水平段骨质破坏。29例肉芽肿型中耳炎CT表现为中耳腔内的软组织密度影，部分有液平，鼓室壁增生、硬化，骨质破坏少见，听小骨可出现吸收破坏，但程度较轻，一般无移位。2例单纯型中耳炎表现为中耳腔内的软组织密度影，1例有液平，鼓室壁骨质硬化，无骨质破坏。
