Original Article


Chronic suppurative otitis media is defined as a chronic inflammation of the middle ear cleft, which presents with recurrent ear discharge through a tympanic membrane perforation. The purpose of this study was to find pattern of bacteriology in patients of atticoantral type of chronic suppurative otitis media as it will help the clinician to decide the effective antibiotics to be prescribed. This prospective and observational study was conducted in the Department of ENT in collaboration with Department of Microbiology, Government Medical College and Hospital, Chandigarh. The ear discharge specimen of all patients meeting the inclusion criteria were collected and sent for microbial examination. Culture positive samples were subjected to antibiotic sensitivity. A total of one hundred ears (mean age 27.33 years) clinically diagnosed with chronic suppurative otitis media, atticoantral type were included in this study based on the preset inclusion and exclusion. The male: female ratio in our patients was 0.94:1. Ninety-seven (96.9%) patients had unilateral disease, while 3 (3.1%) patients had bilateral disease. Twenty-eight percent of the total samples were sterile. The most common bacteria isolated were Pseudomonas aeruginosa (27.1%), Methicillin sensitive Staphylococcus aureus (23.3%) and Proteur mirabilis (6.5%). was sensitive to polymyxin B (100%) followed by ciprofloxacin (46.4%), neomycin (42.9%) and gentamicin (42.9%). Polymyxin B is the most effective antibiotic against the cultured bacteria followed by gentamicin, ciprofloxacin and neomycin.
