This prospective descriptive study aimed to determine the prevalence of chronic suppurative otitis media (CSOM) in children presenting to 5 urban clinics and the Children's Outpatient Department of the Port Moresby General Hospital. 395 children between the ages of 6 months and 12 years were included. 70 (18%) had some form of ear disease. Of the 28 children with CSOM (7%), 18 had unilateral and 10 had bilateral ear pathology. Only 8 of these children presented because of discharging ears. An additional 4 children had dry perforation, 1 had cholesteatoma and 2 had mastoiditis. The high prevalence of CSOM indicates that it is an issue of major public health importance. Risk factors for the development of CSOM were common in the children assessed. Prompt recognition of the problem and management by way of thorough and regular ear wicking should be stressed. Consideration should be given to making ciprofloxacin ear drops available. All clinics should have a functioning auriscope and front-line health workers should be trained to be able to diagnose and treat CSOM. Communities need education about the importance of early diagnosis and management of CSOM.
