Causality of Chronic Suppurative Otitis Media: An Observational Study

Area of Science:

• Otolaryngology
• Microbiology
• Infectious Diseases

Background:

• Chronic suppurative otitis media (CSOM) is an ear disease characterized by a perforated tympanic membrane lasting over 6-12 weeks.
• Identifying the causative pathogens is crucial for effective treatment and management of CSOM.

Purpose of the Study:

• To determine the primary bacterial causes of chronic suppurative otitis media (CSOM) at our institution.
• To provide etiological data that can inform clinical practice and antimicrobial stewardship.

Main Methods:

• Ear swabs were collected from 139 patients diagnosed with CSOM.
• Microbiological culture and sensitivity testing were performed on all samples.
• Statistical analysis was conducted using SPSS version 26.

Main Results:

• The most common pathogen identified was Pseudomonas aeruginosa, present in 81 (58%) of the cases.
• Klebsiella pneumoniae was the second most frequent pathogen, found in 58 (42%) of the cases.
• These findings indicate a predominance of Gram-negative bacilli in CSOM at this center.

Conclusions:

• Pseudomonas aeruginosa is the predominant causative agent of CSOM in the study population.
• The prevalence of Klebsiella pneumoniae also warrants attention in the management of CSOM.
• Understanding local microbial patterns is essential for targeted therapy of chronic ear infections.
