High-frequency hearing loss in children with cleft palate has been documented recently. The present study was designed to investigate whether hearing loss can result solely as a consequence of middle-ear disease in early life or as a result of cleft palate and its sequelae which include middle-ear disease. Our results demonstrate that auditory functions for test frequencies 250-6 000 Hz were not significantly different among the two investigational groups of children with high incidence of middle-ear disease, and a control group of children with virtually no middle-ear disease. However, for high-frequency thresholds (8 000-20 000 Hz), both groups of children with high incidence of middle-ear disease were statistically different from the control group. Moreover, the children with cleft palate had high-frequency hearing that was statistically similar to that of children with normal orofacial structures and high incidence of middle-ear disease. Middle-ear disease alone, then, is a sufficient condition for loss of high-frequency sensitivity.
近期已有文献记载腭裂患儿存在高频听力损失。本研究旨在调查听力损失是否仅由早年的中耳疾病导致，还是由腭裂及其后遗症（包括中耳疾病）引起。我们的研究结果表明，在中耳疾病高发的两组儿童与中耳疾病几乎不存在的对照组儿童中，250 - 6000赫兹测试频率的听觉功能并无显著差异。然而，对于高频阈值（8000 - 20000赫兹），两组中耳疾病高发儿童与对照组在统计学上存在差异。此外，腭裂患儿的高频听力在统计学上与口面部结构正常但中耳疾病高发的儿童相似。因此，仅中耳疾病就是导致高频敏感度丧失的充分条件。
