Epidemiological data on middle-ear pathology during pre-school age are lacking the striking frequency of middle-ear symptoms in this age group. To evaluate the applicability of the impedance test in the younger age groups and to make an epidemiological study of the distribution of tympanogram types in a normal group of pre-school children, an attempt was made to examine all 523 3-year-olds in a limited geographic area. 1005 ears in 504 children (96.4% of those invited) were fully investigated with tympanometry and otoscopy with Siegle's speculum within 4 weeks. 62.8% of the ears showed type A tympanometric curves, 9.8% type B and 27.4% type C. Bilateral type A tympanometric curves were found in 276 children (55.4%). The prevalence of abnormal tympanometry proved to be unexpectedly high in both sexes. This finding is discussed. Even with the use of conventional technique and standard equipment, the 3-year-old clientele presented no testing problems.
关于学龄前儿童中耳病理学的流行病学数据缺乏该年龄组中耳症状的显著频率。为了评估阻抗测试在较年轻年龄组中的适用性，并对正常学龄前儿童组中耳图类型的分布进行流行病学研究，我们尝试对有限地理区域内的所有523名3岁儿童进行检查。在4周内，使用鼓室图测量法和带有西格尔窥镜的耳镜对504名儿童的1005只耳朵（占受邀儿童的96.4%）进行了全面检查。62.8%的耳朵显示为A型鼓室图曲线，9.8%为B型，27.4%为C型。在276名儿童（55.4%）中发现双侧A型鼓室图曲线。鼓室图测量异常的患病率在两性中都出乎意料地高。对这一发现进行了讨论。即使使用传统技术和标准设备，3岁的受检人群也没有出现测试问题。
