A study was designed to find the prevalence of ear wax in children aged 3 to 10 years and to test the belief that large amounts of wax are unlikely to be seen when otitis media is present. Roughly a quarter of the children had appreciable amounts of wax, and there was a gradual decline in prevalence with age. The amount of ear wax appeared to decrease when otitis media was present. The results did not support removing wax when assessing children's ears in general practice.
一项研究旨在查明3至10岁儿童耳垢的患病率，并验证一种观点，即当中耳炎存在时不太可能见到大量耳垢。大约四分之一的儿童有相当数量的耳垢，且患病率随年龄逐渐下降。当中耳炎存在时，耳垢量似乎会减少。研究结果不支持在全科医疗中评估儿童耳部时清理耳垢。
