Background: Otitis media (OM) is a major health problem in both developed and developing countries.
Objective: To determine the pattern of bacterial isolates in patients with chronic suppurative otitis media(CSOM) in Ilorin,
Nigeria.
Methods: A prospective study carried out in University of Ilorin Teaching Hospital, Nigeria among consenting patients
with CSOM attending the ENT clinic over a period of 7months. Informed consent was obtained from the patients or
caregivers and approval for the study obtained from ethical committee. Structured questionnaire was administered and
microbiological analysis done, data obtained was entered into SPSS statistical software and results presented in tables and
figures.
Results: A total of 134 patients aged 5-64yrs with chronic suppurative otitis media were interviewed with a mean age of
17.0 (S.D. =15.1±1.30). About 55.2% of the respondents were under 10yrs. Seventy-two (53.7%) of the respondents were
males with M:F=1.2:1. The gram stain showed predominantly gram negative organisms (71.6%).
Pseudomonas aeruginosa
was the commonest middle ear pathogenic organism identified and the sensitivity pattern highly favoured ciprofloxacin
Conclusion: CSOM is still a childhood problem among the under tens’ more prevalent among males and the commonest
agent is
Pseudomonas aeruginosa. Ciprofloxacin is still the most sensitive antibiotics in vitro.
