Tympanometry and acoustic reflex tests performed on 431 school children aged five to six years showed that eight per cent of the ears screened had type B or type C tympanograms suggestive of otitis media with effusion (1.2 per cent type B, and 6.8 per cent type C). Preliminary otoscopy revealed tympanic membrane appearances consistent with middle ear effusion in a correspondingly low proportion of ears (7.6 per cent), whilst acoustic reflex screening at 105 dB for three frequencies (0.5, 1 and 2 kHz) showed absent reflexes at one or more frequencies in 8.1 per cent of the ears. The findings indicate a relatively low prevalence of otitis media with effusion in children in Nigeria. Possible contributory factors are discussed.
对431名5至6岁学童进行的鼓室导抗图和声反射测试显示，接受筛查的耳朵中有8%呈现B型或C型鼓室导抗图，提示有中耳积液（B型为1.2%，C型为6.8%）。初步耳镜检查显示，中耳积液的鼓膜表现相应比例较低（7.6%），而在105分贝下对三个频率（0.5、1和2千赫）进行声反射筛查时，8.1%的耳朵在一个或多个频率上出现反射消失。研究结果表明，尼日利亚儿童中耳积液的患病率相对较低。文中讨论了可能的促成因素。
