Chronic suppurative otitis media without cholesteatoma (CSOMWC) is usually associated with an increase in air conduction thresholds. However, only a few investigations reported on loss of cochlear function in the pediatric population. We undertook a prospective study in order to further delineate air and bone conduction levels in children with CSOMWC and the possible relationship between sensorineural hearing loss (SNHL) and other clinical characteristics that might reflect the extent of disease. Eighty-seven children were enrolled, 40 of which had bilateral disease. Hence, the total number of diseased ears tested was 127. Audiometric studies were performed three days after achieving a 'dry' ear following medical treatment. We found no statistically significant differences between the bone conduction threshold tested in ears with CSOMWC and control ears. This was also the case in 47 children with unilateral disease when cochlear function was investigated in the diseased and uninvolved ear in the same patient. Clinical correlation showed no association between age, sex, duration of otorrhea and presence of granulation or polyps and the degree of cochlear loss. Our study shows that CSOMWC in children has little effect on cochlear function.
慢性化脓性中耳炎无胆脂瘤（CSOMWC）通常与气导阈值升高有关。然而，仅有少数研究报道了小儿人群的耳蜗功能丧失情况。我们进行了一项前瞻性研究，以进一步明确CSOMWC患儿的气导和骨导水平，以及感音神经性听力损失（SNHL）与其他可能反映疾病程度的临床特征之间的潜在关系。共纳入87名儿童，其中40名患有双侧疾病。因此，受试患耳总数为127只。在药物治疗使耳朵达到“干耳”状态三天后进行听力测定研究。我们发现，CSOMWC患耳与对照耳的骨导阈值之间无统计学显著差异。在47名单侧患病儿童中，对同一患者的患耳和未患耳进行耳蜗功能研究时，情况也是如此。临床相关性分析显示，年龄、性别、耳漏持续时间以及肉芽或息肉的存在与耳蜗功能丧失程度之间无关联。我们的研究表明，儿童CSOMWC对耳蜗功能影响很小。
