中耳炎

Objective: To investigate the effect of open tympanoplasty for patients with cholesteatoma of the middle ear.

目的：探讨开放式鼓室成形术治疗胆脂瘤中耳炎的疗效。

Objective Chronic otitis media with cholesteatoma was exploreed with high reslution CT to improve the accuracy of diagnosis.

目的 探讨胆脂瘤型中耳炎的高分辨率CT征象，提高对本病诊断的准确性。

Most cases of chronic otitis media with cholesteatoma can be diagnosed by HRCT, which is the primary examination method at present.

HRCT对大多数胆脂瘤型慢性中耳炎可作出准确的诊断，是目前该疾病的首选检查方法。

Methods Clinical and HRCT features of 45 cases of chronic otitis media with cholesteatoma were analyzed retrosprctively and correlated with pathological findings.

回顾性分析45例胆脂瘤型慢性中耳炎患者的临床和HRCT检查资料，并与手术病理结果对照。

Methods Eighty CT scans of cholesteatomatous chronic otitis media confirmed by surgical operations were analyzed.

对80例耳手术证实为胆脂瘤型中耳炎的CT影像特点进行分类和归纳。

Objebtive To investigate the CT features of cholesteatomatous chronic otitis media.

目的 探讨和总结胆脂瘤中耳炎的CT表现特点。

Fifty-three ears (96.36%) were constrictive or diploetic type mastoid in the ailing side while 32 ears in the opposite sides.

中耳炎患者患侧乳突呈硬化型或板障型者53耳，占96.36%，而对侧乳突呈硬化型或板障型者32耳，占58.18%。

The abnormality of surfactant of Eustachian tube is an important cause resulting in functional disorder of Eustachian tube. Ectogenic surfactant is effective for the treatment of SOM.

咽鼓管内表面活性物质的异常是引起咽鼓管功能障碍的重要原因之一，外源性表面活性物质对分泌性中耳炎有一定疗效。

Methods Guinea pigs suffering from SOM were divided into three groups randomly, 6 for each group. Ectogenic surfactant, dexamethasone and 0.9% sodium chloride solution were injected into guiea pigs' tympanic cavities of group A, B and C respectively. The biochemical components and activity change of surfactant of Eustachian tube were analysed.

将分泌性中耳炎豚鼠动物模型随机分为A、B、C3组，每组各6只（12耳），分别用外源性表面活性物质、地塞米松和生理盐水注入豚鼠中耳腔内，然后观察豚鼠中耳变化；分析豚鼠咽鼓管内表面活性物质的生化成分和活性变化。

In theory, this will help to keep the Eustachian tubes clear and allow mucus to drain from the middle ear, but again, this has not been proved to be an effective treatment for otitis media.

在理论上，这将有助于保持咽鼓管管清楚，并允许粘液流失从中耳，但再次，这并没有被证明是一种有效的治疗中耳炎。
