Chronic suppurative otitis media: A review

Objectives: Chronic suppurative otitis media (CSOM) remains one of the most common childhood chronic infectious diseases worldwide. Although microbial, immunological, and genetically determined factors, as welt as Eustachian tube characteristics, are supposed to be involved in the pathogenesis of CSOM, many aspects of the pathogenesis of CSOM still need to be clarified. Optimal treatment strategy has not been established yet. The objective of this review is to present and evaluate the current state of knowledge of CSOM. Design: Systematic narrative review. Methods: A PubMed search (1966-January 2005) was performed for studies on epidemiology, pathogenesis, clinical. management, and complications of CSOM. All included articles were categorized according to level of evidence. Results: Five hundred and fifty papers were identified, of which 79 were found to be relevant for this review. The definition of CSOM was found to vary. CSOM is a multifactorial disease. Regarding management of CSOM, there is no consensus as to what the optimal management strategy should entail. No convincing evidence is available for most medical and surgical. therapies. Topical quinolones have proven effective, but need further monitoring regarding adverse effects. Conclusions and recommendations: Important goats in research of CSOM should be achieving consensus about the definition of CSOM and gaining more in-depth knowledge of the pathogenesis of CSOM, especially the role of innate and adaptive immunity. There is also a need for further well-designed studies on the effectiveness of various management strategies for CSOM. (c) 2005 Elsevier Ireland Ltd. All rights reserved.
