Abstract:
This observational study was conducted to know the bacteriological pattern of chronic suppurative otitis media. For this 110 patients of Chronic Suppurative Otitis Media (CSOM) were selected from January 2006 to December 2007 at the out patient department of Otolaryngology and Head Neck surgery, BSMMU and Dhaka Medical College Hospital, Dhaka. Among the 110 patients unilateral involvement was 76.36% and bilateral involvement was 23.64%. Ninety percent patients presented with tubotympanic variety and 10% patients presented with attico-antral variety. Bacteriologically pure growth was found in 79.09% cases, mixed growth in 10.91% cases, no growth in 10% cases. Only aerobic bacteria were isolated in the present series. Pseudomonas aeruginosa was the most common organism (43.68%) isolated in pure culture followed by staphylococcus aureus 27.59%, E. coli 10.35%, Kleibsiella spp. 9.19%, proteus spp. 8.04%. Amikacin was the most effective antibiotic followed by Gentamycin, Ciprofloxacin, Ceftazidime, Cetriaxone. Before giving therapy bacterial growth and sensitivity pattern is to be known where facilities are available.
