Chronic suppurative otitis media.

OBJECTIVE: To review various aspects of chronic suppurative otitis media (CSOM). DATA SOURCES: A MEDLINE search and extensive review of articles provided the information for this review. DATA EXTRACTION: Studies describing the epidemiology, microbiology, risk factors, pathology, diagnosis, treatment, complications, and recurrence of CSOM were included. DATA SYNTHESIS: Pseudomonas aeruginosa and anaerobes are the most predominant bacteria found in CSOM. Treatment with otic, oral, or parenteral drugs (e.g., neomycin/polymyxin B/hydrocortisone otic, ciprofloxacin, ceftazidime, or aminoglycosides) should be guided by ear fluid culture results. Prompt treatment with effective and safe antibiotics may prevent complications of CSOM.
CONCLUSIONS: Treatment of CSOM has improved as a result of availability of effective otic and oral antibiotics. Treatment of the anaerobic infection with antibiotics should be studied further.
