Middle ear pathogens in otitis-prone children

Area of Science:

• Pediatric Otolaryngology
• Infectious Diseases

Background:

• Recurrent otitis media and persistent middle ear effusion are common in children.
• Middle ear infections can be caused by various bacterial pathogens.
• Antibiotic resistance is a growing concern in treating pediatric infections.

Purpose of the Study:

• To evaluate the indications, fluid characteristics, and microbial findings in children undergoing myringotomy with tubes for recurrent otitis media.
• To assess the prevalence of antibiotic resistance in middle ear pathogens.
• To determine the post-procedure prognosis for recurrent otitis media after surgical intervention.

Main Methods:

• A cohort of 191 children with recurrent otitis media and persistent middle ear effusion underwent myringotomy and tube insertion.
• Middle ear fluid cultures were obtained during the procedure.
• Pathogen identification, culture sensitivity, and pre- and post-procedure otitis media frequency were analyzed.

Main Results:

• Mucoid effusion was present in 67% of cases.
• Bacterial pathogens were isolated in 24% of middle ear cultures.
• Common pathogens included *Hemophilus influenzae*, *Streptococcus pneumoniae*, *Moraxella catarrhalis*, and *Staphylococcus aureus*.
• A high rate of antibiotic resistance was observed, with 75% of *Streptococcus pneumoniae* isolates being penicillin-resistant.

Conclusions:

• Myringotomy with tubes is an effective treatment for recurrent otitis media and persistent middle ear effusion in children.
• The procedure provides a favorable prognosis even when infections involve antibiotic-resistant organisms.
• Understanding microbial patterns and resistance is crucial for managing pediatric otitis media.
