Based on repetitive tympanometric screenings of infants and 2-year-old children, the spontaneous improvement of secretory otitis has been studied. In 2-year-old children, 53% of ears with type B improved during the three months from the first to the second evaluation, 67% from the second to the third, and 84% from the third to the fourth. At the same time, tympanogram deteriorated to type B in other ears so that during a nine-month period, 28.6% of all ears with at least one screening have had type B. It was concluded that impedance screening as a prophylactic means to diagnose a middle ear disease early would be meaningless. It will lead to excessive treatment of secretory otitis, as one cannot take other consequences of one screening than to repeat it six months later.
基于对婴儿和2岁儿童的反复鼓室图筛查，对分泌性中耳炎的自然改善情况进行了研究。在2岁儿童中，从第一次评估到第二次评估的三个月内，B型耳中有53%得到改善，从第二次到第三次评估时改善率为67%，从第三次到第四次评估时为84%。与此同时，其他耳朵的鼓室图恶化为B型，因此在九个月的时间里，至少接受过一次筛查的所有耳朵中有28.6%出现过B型。得出的结论是，阻抗筛查作为早期诊断中耳疾病的预防手段毫无意义。这将导致对分泌性中耳炎的过度治疗，因为除了六个月后重复筛查外，无法考虑单次筛查的其他后果。
