摘　　要：分泌性中耳炎与乳突气房的发育程度有关，谁为因果，意见尚不一致。在总结２００余耳分泌性中耳炎诊治经验的基础上，随机对４４例（７５耳）分泌性中耳炎患者和４０例（８０耳）无耳病者进行观察，全部观察耳均摄乳突Ｓｃｈｕｌｅｒ位片，用Ｄｉａｍａｎｔ法测量并计算Ｘ线片上显示的乳突气房的几何学面积，将其分为两型：气化良好型（气化面积＞６ｃｍ２）和气化不良型（气化面积＜６ｃｍ２）。１５５耳中气化良好型６９耳，５（６．７％）耳患分泌性中耳炎；气化不良型８６耳，７０（８１．４％）耳发病。比较两种发育类型乳突中分泌性中耳炎的发病数差异有显著性（Ｐ＜０．００１）。认为乳突气化不良是导致分泌性中耳炎发病因素之一。earsof44patientswithsecretoryotitisand80earsof40patientswithnormalearwereobservedandreserched.AlofthecaseswerereceivedX-rayexaminationofmastoidprocessinSchuler′slateralprojection.Thesizeoftheaircelsystemwasobtainedbyplanimetry:themethodwhatwasoriginalydevisedbyDiamant.Theoutlineofthemastoidaircelsystem(MACS)wasmarkedoutontheradiographandthentransferredtographpaperwherethenumberofmm2canbecounteddirectly.AccordingtomeasuringtheplanimetricareaofMACS.Themastoidsweredividedintotwocategories:pneumatizationtypeandnopneumatizationtype.5of69earswithpneumatiza-tionmastoid(7.2%)weresecretoryotitis,while70of86earswithnopneumatization(81.4%)weresecretoryotitis.Itwassignificantlydiferent(P<0.001)camparingthenumberofearswithsecreto-ryotitis.Webelievethatthedegreeofmastoidpneumatizationisassociatedwiththeoccurringandprognosisofsecretoryotitismedia.
