The aim of this study was to estimate the prevalence of the different types of eardrum pathology in a cohort (cohort 1955) who were children before the era of ventilation tubes, and to compare these findings with the prevalence of eardrum pathology in a previous published cohort study on 222 children followed since the age of four years (cohort 1975) in the era of ventilation tubes. All inhabitants of Hillerød county born in 1955 were invited to a screening examination including otomicroscopy, tympanometry and audiometry. All eardrum pathology was recorded. In cohort 1955, 59% of 460 possible, attended the examination. In addition 9% returned a questionnaire enquiring their otologic history. In the cohort with no grommets, retraction of Shrapnell's membrane was found in 4% of the ears compared to 20% in the cohort with grommets. Tensa pathology was found in 6% of the ears in the old cohort and in 24% in the young cohort. Despite the increased attention to the diagnosis of secretory otitis, and the increased rate of surgical treatment, the prevalence of eardrum pathology seems to have increased. The reason for this increase is discussed.
本研究的目的是评估在鼓膜置管时代之前为儿童的一个队列（1955年队列）中不同类型鼓膜病变的患病率，并将这些结果与此前发表的一项队列研究中222名自四岁起开始随访的儿童（1975年队列，处于鼓膜置管时代）的鼓膜病变患病率进行比较。邀请了1955年出生的希勒勒德县所有居民参加包括耳显微镜检查、鼓室图检查和听力测定在内的筛查检查。记录所有鼓膜病变情况。在1955年队列中，460名可能参加检查的人中有59%参加了检查。此外，9%的人返回了一份询问其耳部病史的问卷。在未进行鼓膜置管的队列中，4%的耳朵发现了松弛部鼓膜内陷，而在进行鼓膜置管的队列中这一比例为20%。在老年队列中，6%的耳朵发现了鼓膜紧张部病变，而在年轻队列中这一比例为24%。尽管对分泌性中耳炎的诊断关注度增加，且手术治疗率上升，但鼓膜病变的患病率似乎仍有所增加。本文讨论了这种增加的原因。
