This study presents the results on 1305 children with speech disorders. The examination includes ENT-inspection, audiometry, speech-evaluations and if required, psychological tests. In 48% we found hearing losses, most frequently in the age up to four years. In 95% hearing losses were fluctuating about 20 decibels, caused by malfunction of the tube or by adenoids, not even in autumn and winter, but also all the year. In this case, fluctuating hearing function reduces the total hearing input over the year. In only 5% we found cochlear hearing loss. In hearing impaired children speech development was significantly more depressed in all dimensions in comparison to normal hearing children. This study does impressive demonstrate the necessity of follow-up microscopic evaluations of the tympanic membrane and audiometry as well as the consequence operative therapy including adenoidectomy and insertion of ventilation tubes. With this concept, only 37% of the children required speech therapy.
本研究展示了1305名言语障碍儿童的研究结果。检查包括耳鼻喉检查、听力测定、言语评估，如有需要还包括心理测试。我们发现48%的儿童有听力损失，最常见于4岁以下儿童。95%的听力损失波动约20分贝，是由咽鼓管功能障碍或腺样体引起的，不仅在秋冬季节，全年都有。在这种情况下，听力功能的波动会降低全年的总听力输入。仅5%的儿童有耳蜗性听力损失。与听力正常的儿童相比，听力受损儿童的言语发展在各个维度上均明显更迟缓。这项研究令人印象深刻地证明了对鼓膜进行后续显微镜评估和听力测定的必要性，以及包括腺样体切除术和插入通气管在内的手术治疗的结果。采用这一理念，只有37%的儿童需要言语治疗。
