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。
To review the degree of mastoid gasification in adult patients with secretory otitis media (SOM), and to analyze the role of mastoid dysplasia in the pathogenesis of SOM. Methods: The mastoid Schuller radiography was performed on 105 ears of SOM patients and 20 ears of 40 ears of normal ear-free adults. The contour of the air space was drawn and the geometric area was calculated. The areas were divided into gasification-good type and gasification-poor type. conduct statistical analysis. Results: Sick ear mastoid dysplasia, unaffected ear gasification and more good, the former suffering from SOM was significantly higher than the latter. Conclusion: Dysplastic dysplasia in mastoid plays an important role in the pathogenesis of SOM and is a risk factor for adult SOM.
