Sequelae of recurrent acute otitis media. Ten-year follow-up of a prospectively studied cohort of children.
In a cohort of 113 children prospectively followed from birth to the age of 3, two subgroups were discerned: one with recurrent acute otitis media (rAOM), the other subgroup with no AOM at all ("healthy" children). At further follow-up at the age of 10, no child had AOM or secretory otitis media (SOM), but between 3 and 7 y of age the rAOM subgroup was characterized by a significantly higher incidence of AOM as well as protracted secretory otitis media (SOM) episodes than was the "healthy" subgroup. The two subgroups did not differ significantly in hearing-thresholds at pure tone audiometry. After the age of 7, the incidence of AOM was the same in both groups. It is concluded that children with frequent AOM episodes before the age of 3 need long-term follow-up to school age, but seem not be predisposed to chronic SOM.
