During a 1-year period, 151 children, 1/2-6 years old, attending group care, were followed by monthly tympanometry in order to describe spontaneous variations in the tympanograms in relation to age and time of the year. Furthermore, the number of spontaneous variations during the year was assessed. Significantly more flat curves were seen in children 1/2-1 year old than in the older age groups, indicating a high frequency of spontaneous remission about the age of 2 years. In all age groups more normal tympanograms were seen during late summer than during the rest of the year. Spontaneous variations in the tympanograms were taking place 2.9 times (mean) during the period of observation. Correlation was found between the presence of catarrh and flat curves. Furthermore, in children greater than or equal to 3 years old, a correlation between case history signs of enlarged adenoids and flat curves lasting for 3 months or more was found. It was concluded that persistence of flat curves in children 1/2-1 (2) years old usually requires no treatment, as spontaneous remission can be expected, whereas persistence of flat curves for greater than or equal to 3 months in children greater than or equal to (2) 3 years old indicates that treatment (adenoidectomy) should be performed.
在为期1年的时间里，对151名年龄在半岁至6岁、参加集体照料的儿童进行了每月一次的鼓室图测量，以描述鼓室图与年龄和一年中时间相关的自发变化。此外，还评估了一年中自发变化的次数。半岁至1岁的儿童中出现明显更多的平坦曲线，高于年龄较大的组，这表明在2岁左右自发缓解的频率较高。在所有年龄组中，夏末时出现的正常鼓室图比一年中的其他时间更多。在观察期内，鼓室图的自发变化平均发生2.9次。发现卡他症状与平坦曲线之间存在相关性。此外，在3岁及以上的儿童中，发现腺样体肿大的病史体征与持续3个月或更长时间的平坦曲线之间存在相关性。得出的结论是，半岁至1（2）岁儿童中平坦曲线的持续通常无需治疗，因为可以预期会自发缓解，而3岁及以上（2）3岁儿童中平坦曲线持续3个月及以上则表明应进行治疗（腺样体切除术）。
