Changing incidence of sinus infection in children

Abstract This study presents the results of a 20 year review of maxillary sinus wash-outs performed on children. The results show a decreasing incidence of purulent sinusitis over the study period. Only 17 per cent of antral wash-outs undertaken yielded pus, indicating that surgical practice has failed to adequately take account of the changing disease incidence.
