AbstractTympanometry 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 consistant 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.
