BACTERIOLOGICAL PROFILE OF CHRONIC SUPPURATIVE OTITIS MEDIAAT TERTIARY CARE HEALTH CENTRE

Abstract

Background: Chronic suppurative otitis media (CSOM) is a disease affecting the middle ear and mastoid cavity, leading to considerable morbidity by causing hearing loss; and even life threatening complications in squamosal type of CSOM, if left untreated over long periods of time. Hence it isimperative to treat the persistent ear discharge in CSOM according to the antibioticssusceptibility of the organismsisolated.Aim:Thisstudy was carried out to examine the current local bacteriological prole ofCSOM and to study the antibiotic susceptibility pattern of the isolates.Methods:We carried out a retrospective analysis of earswab culturesfrom 31 unilateral CSOM casesseen at the Ear-Nose-Throat clinics of a referral health institution during a 8 month period ending 2020. Sensitivitiesto seven locally available antibiotics were analyzed.Results:We analyzed 17 earswab culture resultsfrom 31 patients with age ranging from 5 yearto 60 years and a mean 24.87 years. Pseudomonas aeruginosa wasthe most commonisolatedbacteria (34.4%[11/31])followedbyAcinetobacterSpecies(6.3%[2/31]), andProteusMirabilis(6.3%[2/31]).Themost andleast sensitive bacteria were Pseudomonas aeruginosa and Acinetobacter Species , respectively. The most effective antibiotics were gentamicin and Ciprooxacin. Conclusion:Pseudomonas is the most common bacteria involved in CSOM in this part of the country.
