摘要
目的探讨正常成人乳突气腔容积大小及其与既往儿童期中耳炎的关系。方法 40例(80耳)成人依据儿童期有无中耳炎病史分为研究组(共20例,其中双耳患病12例,单耳患病8例)和对照组(20例),通过颞骨CT扫描三维重建乳突气腔后测量其乳突气腔容积,并分析其与儿童期中耳炎病史的关系。结果 40例(80耳)成人乳突气腔容积大小均值为10.4±1.8ml。既往健康耳(48耳)与既往患病耳(32耳)的乳突气腔容积大小分别为9.7±2.2ml和6.3±1.7ml,前者大于后者,差异有统计学意义(P<0.05)。研究组中既往单耳患病者的健康耳(8耳)与患病耳(8耳)的乳突气腔容积大小均值分别为9.2±1.3ml和5.8±3.6ml,前者大于后者,差异有统计学意义(P<0.05)。对照组20例(40耳)乳突气腔容积大小均值为10.1±4.4ml,与研究组既往单耳患病者的健康耳(8耳)比较,差异无统计学意义(P>0.05)。结论正常成人乳突气腔容积存在较大个体差异,既往儿童期反复发作的中耳炎可能是导致成年后乳突气腔容积减小的原因。
