【摘要】 回顾成人分泌性中耳炎（ＳＯＭ）患者乳突气化程度，分析乳突气房发育不良在ＳＯＭ发病中的作用。方法：对１０５耳ＳＯＭ患者及２０人４０耳正常无耳病成人进行乳突Ｓｃｈｕｌｌｅｒ氏摄片，画出气房轮廓，计算其几何面积，将其分为气化良好型和气化不良型，并进行统计分析。结果：病耳乳突气房均发育不良，未患病耳气化多良好，前者患ＳＯＭ的机率明显高于后者。结论：乳突气房发育不良在ＳＯＭ发病中起着重要作用，是成人ＳＯＭ发生的危险因素。更多还原

【Abstract】 One hundred and five ears of 68 patients with secretory otitis media (SOM) and 40 ears of 20 normal subjects were studied retrospetively in order to elucidate the role of underdeveloped mastoid pneumatization in pathogenesis of SOM in adults. Method:All of the ears had X-ray examination of mastoid process in Schuller’s lateral projection. The size of the air cell system was obtained by the Diamant’s planimetry method. The outline of the mastoid air cell system (MACS) was marked out on the radiographs. The planimetric area of MACS was measured and analyzed. The mastoids were divided into two categories: pneumatization type and nonpneumatization type. The relationship between SOM and the two pneumatization categories was analysed statistically. Results:All the mastoids with SOM lacked pneumatization and the normal mas- tioid were pnermatized. The rate of SOM in the patients with reduced mastoid pneumatization was higher than those with pneumatization. Conclusion:The underdeveloped pneumatization of mastoid played an important role in the development of secretory otitis media in adults.更多还原
