To investigate the epidemiology of cerumen impaction among children of municipal kindergartens in Wuhan.
The ear canal of children of municipal kindergartens in Wuhan was examined using an electric otoscope by the same otologist in 2005, 2006 and 2012, with age, gender, ears and the nature of cerumen (dry cerumen or wet cerumen) recorded. A chi-square test was performed to investigate for significant differences between cerumen impaction rates and the recorded variables.
A total of 1,214, 1863 and 5205 children were examined in 2005, 2006 and 2012, and cerumen impaction prevalence rates for each year were 17.2%, 15.4% and 10%, respectively. Prevalence of cerumen impaction was significantly lower in 2012 than in 2005 or 2006. In 2005, dry cerumen impaction accounted for 22.2% of the total dry cerumen, while wet cerumen impaction only accounted for 5% of the total wet cerumen, showing a statistically significant difference.
The prevalence of cerumen impaction among children of kindergartens in Wuhan is higher than 10%, and children with dry cerumen are more prone to cerumen impaction. Annual otological examination of kindergarten children is recommended. And improved community ear health promotion activities should reduce the avoidable prevalence of cerumen impaction in pediatric population.
调查武汉市市级幼儿园儿童耵聍栓塞的流行病学情况。
2005年、2006年和2012年，由同一名耳科医生使用电子耳镜对武汉市市级幼儿园儿童的耳道进行检查，记录年龄、性别、耳别以及耵聍性质（干性耵聍或湿性耵聍）。采用卡方检验研究耵聍栓塞发生率与所记录变量之间的显著差异。
2005年、2006年和2012年分别检查了1214名、1863名和5205名儿童，每年的耵聍栓塞患病率分别为17.2%、15.4%和10%。2012年耵聍栓塞患病率显著低于2005年或2006年。2005年，干性耵聍栓塞占干性耵聍总数的22.2%，而湿性耵聍栓塞仅占湿性耵聍总数的5%，差异有统计学意义。
武汉市幼儿园儿童耵聍栓塞患病率高于10%，干性耵聍儿童更易发生耵聍栓塞。建议对幼儿园儿童进行年度耳科检查。加强社区耳部健康促进活动应可降低儿童人群中可避免的耵聍栓塞患病率。
