- Chronic Suppurative Otitis Media: A Prospective Descriptive Study of the Microbiology and Antimicrobial Susceptibility Patterns Tessa K. Suttle Timothy Els Julia Toman Danielle Curtis Rheese McNab Anna Sizemore Margaret Van Cleve Richard A. Brombacher Otolaryngology–Head and Neck Surgery AbstractObjectiveThis study aims to identify dominant causative pathogens of chronic suppurative otitis media (CSOM) and their antimicrobial susceptibility patterns. The secondary objective is to assess the cholesteatoma concurrence among this population.Study DesignA prospective descriptive study.SettingPort Elizabeth Provincial Hospital, Eastern Cape, South Africa.MethodsAural swabs of purulent otorrhoea were collected from patients with CSOM attending the otorhinolaryngology outpatient department between April 2022 and June 2023. Samples were analyzed to determine the microbiological spectrum and evaluate antimicrobial sensitivities. Patient files were reviewed to identify cases with cholesteatoma. The study population size of 169 enabled representative results for a confidence interval of 90%.ResultsPatients were divided into 2 age categories: children (0‐12 years) and adults (>12 years). Adults represented the majority of cases (76.9%) and females (58.6%) were affected more than males. Fungal isolates, Candida species and Aspergillus species, were the most common (20.8%). This was followed by Pseudomonas aeruginosa (12.4%) and Staphylococcus aureus (11.8%). 3.6% of cases cultured Mycobacterial tuberculosis which was high compared to global estimates. Susceptibility patterns showed 94.3% sensitivity of fungal cultures to fluconazole. Pseudomonas aeruginosa was 100% susceptible to piperacillin‐tazobactam and cefepime, but only 76.2% sensitive to ciprofloxacin. Cholesteatoma concurrence was identified in 17.8%.ConclusionCSOM remains a public health challenge. This study highlights the need to consider fungal etiology in instances where standard antibiotic treatments prove ineffective. Given the variety of cultured organisms and their susceptibility patterns, incorporating culture‐directed therapy should be considered standard practice for chronic otorrhoea patients. 10.1002/ohn.708 http://creativecommons.org/licenses/by-nc-nd/4.0/
