结果 ：66例中耳胆脂瘤HRCT表现为鼓室/鼓窦内团块状软组织影和骨质改变，包括听骨硬化、移位、破坏，盾板破坏及中耳腔扩大，有的还伴有乙状窦、天盖、面神经管及水平半规管的破坏。

Results HRCT findings of 45 cases of chronic otitis media with cholesteatoma included abnormal soft-tissue mass shadows in tympanic cavity of middle ear,sclerotic mastoid were observed in most cases, and bone changes including enlargment of the tympanic cavity with sclerotic border, the dislocation and destruction of the ossicles.The sigmoid sinus plate,tympanic tegmen, semicircular canal and facial nerve canal were destroyed in severe cases.

结果 胆脂瘤型慢性中耳炎患者HRCT表现：①45例均见中耳腔内团块状软组织影；②40例为硬化型乳突（88.9%）；③骨质改变包括中耳腔扩大和周缘骨质硬化、听小骨的移位、破坏、乳突骨质的破坏，严重者可伴有乙状窦壁、鼓室盖、面神经管及半规管的破坏。

Methods: 8 patient of cholesteatoma tympani with 10 ears were irrigated with 3% Purslane after oto-endoscopic.

对8例10耳单纯上鼓室胆脂瘤或伴外耳道后上壁部分缺损、CT示鼓窦、鼓室及乳突有软组织影的胆脂瘤型中耳炎采用耳内镜手术配合3%马齿笕溶液冲治疗。

Methods 300 cases (560 ears)of temporal CT axial images which were divided into two groups were retrospectively analyzed by statistics methods. There were 158 cases(316 ears)in normal group and 142 cases(244 ears)in abnormal group .The incidence of high jugular bulb , dehiscent jugular bulb, anterior location of sigmoid sinus, large sinus tympani, aberrant internal carotid artery, dehiscent of the facial nerve canal, excess of Korner's septum and mastoid antrum dysplasia were recorded.

回顾性分析300例(560耳)颞骨的HRCT轴位像，根据诊断结果将其分为正常组与疾病组，正常组158例(316耳)，疾病组142例(244耳)，统计以下变异的发生率：①颈静脉球高位②颈静脉球裸露③乙状窦前置④鼓室窦深位⑤迷走颈内动脉⑥面神经管水平段裸露⑦岩鳞隔过长⑧鼓窦缺如，并对结果进行统计学分析。

Results Spiral CT findings of cholesteatomtous tympanitis included: soft tissue mass in the tympanium, tympanal sinus and mastoid,destruction of the bone including ossicles chain,secutum,facial nerve canal,semricirular canal,sigmoid sinus plate, tegmenttympanic.

结果：胆脂瘤型中耳炎的螺旋CT表现为鼓室、鼓窦及乳突区软组织肿块，常伴有骨质破坏，其中包括听小骨、盾板、面神经管、半规管、乙状窦及鼓室盖骨质破坏。

METHODS: Microanatomical study was carried out on 40 adult temporal bones with operation microscope to measure the height of pyramidal eminence and facial nerve canal, and the depth of facial recess and tympanic sinus.

取成人颞骨40侧(左：23，右：17)，在手术显微镜下观察、测量了锥隆起及面神经管的高度、面隐窝和鼓室窦的深度。

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。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
