Adult onset otitis media with effusion in Lagos

The documented reports on adult onset OME is scanty world wide, this study was prompted by the increasing trend of OME in our adult patients with the aim of determining the prevalence, predisposing factors and treatment outcome of the disease.

A prospective study was carried out over a two year period at the Otolaryngology Clinic of Lagos University Teaching Hospital Lagos Nigeria, on 195 patients referred to the clinic with provisional diagnosis of OME. The patients had clinical evaluation, pure tone audiometry, tympanometry while a few had fibre optic nasopharyngoscopy and biopsy done.

A hospital based prevalence of 2.6% was recorded in the Otolaryngology clinic during the study period, with infective and allergic sinusitis as the major predisposing factors to OME in adult patients. Majority 58 (92.06%) patients were treated conservatively and recurrence was seen in 8 (12.7%) of the patients without any untoward effects. OME, though recognised as a childhood disease may be as prevalent in adult as in childhood but with less complication.

OME as a single clinical feature or in association with allergy or sinusitis is most unlikely to habour NPC therefore nasopharyngoscopy and biopsy are likely to give a low yield of positive biopsy in isolated OME in adult and the cost implication of this must be borne in mind.
