The changes in prevalence of secretory otitis from summer to winter were analyzed on the basis of tympanometry in 288 healthy 4-year-old children in August and November 1979 and February 1980. There was a significant increase in the frequency of secretory otitis and a significant deterioration of the tympanometric conditions from summer to winter. At each trial, half of the ears changed type, and significantly more ears deteriorated than improved. During winter secretory otitis also shows a tendency to spontaneous improvement, although this is not so pronounced as in the 2-year-old children.
基于1979年8月、11月及1980年2月对288名4岁健康儿童进行的鼓室导抗图检查结果，分析了分泌性中耳炎从夏季到冬季的患病率变化。从夏季到冬季，分泌性中耳炎的发病率显著增加，鼓室导抗图情况显著恶化。每次检查时，半数耳朵的类型发生了变化，病情恶化的耳朵明显多于病情改善的耳朵。在冬季，分泌性中耳炎也有自发改善的趋势，尽管不如2岁儿童那么明显。
