75 ears of 44 patients with secretory otitis and 80 ears of 40 patients with normal ear were observed and reserched. All of the cases were received X-ray examination of mastoid process in Schuller's lateral projection. The size of the air cell system was obtained by planimetry: the method what was originally devised by Diamant. The outline of the mastoid air cell system (MACS) was marked out on the radiograph and then transferred to graph paper where the number of mm2 can be counted directly. According to measuring the planimetric area of MACS. The mastoids were divided into two categories: pneumatization type and nopneumatization type. 5 of 69 ears with pneumatization mastoid (7.2%) were secretory otitis, while 70 of 86 ears with nopneumatization (81.4%) were secretory otitis. It was significantly different (P < 0.001) camparing the number of ears with secretory otitis. We believe that the degree of mastoid pneumatization is associated with the occurring and prognosis of secretory otitismedia.
对44例分泌性中耳炎患者的75耳和40例正常耳的80耳进行了观察和研究。所有病例均接受了许勒位乳突X线检查。气房系统的大小通过面积测量法获得：该方法最初由戴曼特设计。在X线片上标记出乳突气房系统（MACS）的轮廓，然后转移到绘图纸上，在那里可以直接计算平方毫米数。根据测量MACS的平面面积，将乳突分为两类：气化型和非气化型。69耳气化型乳突中有5耳（7.2%）为分泌性中耳炎，而86耳非气化型中有70耳（81.4%）为分泌性中耳炎。分泌性中耳炎耳数比较差异有统计学意义（P<0.001）。我们认为乳突气化程度与分泌性中耳炎的发生及预后有关。
