This study implies that the hypothesis that acute otitis media (AOM) in infancy inhibits the growth of the mastoid system cannot be accepted.
To establish a relationship between AOM in children and their mastoid pneumatization development.
Lateral Schüller mastoid radiographs (LMRs) were measured in two groups of children at ages 2-11 years. Group A (n=116) had a history of recurrent AOM; group B (n=108) had no such history. Patients were treated in a private clinic. Data were analysed at Tel Aviv University. The patients had their LMR taken and measured planimetrically. LMR areas on left and right sides were compared in each group and age and were tested for possible differences using the paired Student's t test. When no left/right difference was detected, the values were averaged. Groups A and B were compared at different ages using two-tailed two-sample unequal variance and correlation coefficients.
The analyses show that the LMR area became gradually and significantly larger with age in group A (R2=0.858; p<0.05). It did not develop significantly in group B.
本研究表明，婴儿期急性中耳炎（AOM）会抑制乳突系统生长这一假设不能被接受。
建立儿童AOM与其乳突气化发育之间的关系。
对两组2至11岁儿童的许勒氏位乳突侧位X线片（LMR）进行测量。A组（n = 116）有复发性AOM病史；B组（n = 108）无此类病史。患者在一家私人诊所接受治疗。数据在特拉维夫大学进行分析。对患者进行LMR拍摄并采用面积测量法进行测量。对每组中左右两侧的LMR面积进行比较，并按年龄进行比较，使用配对t检验检测可能存在的差异。当未检测到左右差异时，将数值取平均值。使用双尾双样本不等方差和相关系数对不同年龄的A组和B组进行比较。
分析表明，A组中LMR面积随年龄增长逐渐显著增大（R2 = 0.858；p < 0.05）。B组中LMR面积无显著变化。
