78 children had been treated for secretory otitis media at the age of 4.4, on the average. At the age of 18.6, their hearing was checked by means of conventional and high frequency (HF) audiometry. In the conventional range, the average hearing level was nearly normal and no air-bone gap could be found. In HF-range, the average hearing level decreased clearly but the HF-hearing level was significantly affected only in cases in which an air-bone gap exceeding 40 dB and more had existed during the active secretory otitis.
平均年龄4.4岁时，78名儿童曾接受过分泌性中耳炎治疗。在18.6岁时，通过传统和高频听力测定法对他们的听力进行了检查。在传统听力范围内，平均听力水平接近正常，未发现气骨导差。在高频范围内，平均听力水平明显下降，但仅在活动性分泌性中耳炎期间气骨导差超过40分贝及以上的病例中，高频听力水平受到显著影响。
