Abstract

Background: Recurrent or persistent acute otitis media remains a clinical challenge. Objective: To describe the clinical and microbiological characteristics of children with recurrent or persistent acute otitis media. Methods: A prospective descriptive study was conducted on 62  children with  recurrent or persistent acute otitis media from July 2024 to June 2025. Results: Recurrent or persistent acute otitis media was more frequent in boys than in girls, with a male-to-female ratio of 1.7:1. The majority of patients were under 2 years old (70.9%). The most common symptoms during exacerbations were rhinorrhea (98.4%) and cough (95.2%), whereas fever was present in 54.8%, and ear-specific symptoms were less frequent. Bilateral ear involvement was observed in 79% of cases. Haemophilus influenzae was the most frequently isolated pathogen, accounting for 53.2% of isolates. Conclusion: Recurrent or persistent acute otitis media predominantly occurs in in children under 2 years old. Children often present with symptoms related to adjacent lesions such as acute pharyngitis or adenoiditis, while ear-specific or systemic manifestations such as fever are less common. H. influenzae is the most commonly isolated pathogen
