A prospective study of otitis media with effusion in adults and children.

A prospective study of otitis media with effusion (OME) in both adults and children has been carried out. 75 new adult patients were seen during a 4-year period. Of these, 13 had associated diseases which could reasonably be considered to have been a cause of their effusion. Over a 2-year period, 192 new children with OME were seen. There was a significantly higher incidence of previous otalgia and/or aural discharge in the children as compared to the adults (P less than or equal to 0.001). The adults had significantly more serous effusions than the children (P less than or equal to 0.001), but both mucoid and serous effusions occurred in both groups. Similar rates of spontaneous resolution were observed in the 2 groups. Within the adult group, patients with a history of upper respiratory infection at the onset of hearing loss were significantly more likely to have spontaneous resolution of their effusion (P less than or equal to 0.02).
