Acute mastoiditis incidence remains stable in Denmark despite conservative acute otitis media treatment. Complications are rare, and outcomes are favorable, with low bacterial resistance to penicillin.
Area of Science:
- Pediatric Otolaryngology
- Infectious Diseases
- Public Health
Background:
- Conservative management of acute otitis media (AOM) may increase complication risks.
- This study investigates acute mastoiditis trends in a region with conservative AOM treatment guidelines.
Purpose of the Study:
- To evaluate changes in the incidence of acute mastoiditis in children.
- To analyze clinical and microbiological findings, complications, and treatment outcomes.
Main Methods:
- Retrospective review of 214 children (0-15 years) diagnosed with acute mastoiditis from 1998-2007 in eastern Denmark.
- Data collection included clinical presentation, microbiological cultures, and treatment interventions.
Main Results:
- Stable incidence of acute mastoiditis (4.8/100,000 children/year).
- Common symptoms included ear protrusion and retroauricular swelling; 32% had abscesses.
- Streptococcus pneumoniae and group A streptococci were prevalent, with 94% penicillin susceptibility. Low complication rate (1.9%).
Conclusions:
- Acute mastoiditis incidence is stable in eastern Denmark under conservative AOM management.
- Low bacterial resistance to penicillin and rare complications indicate favorable treatment outcomes.
- No severe post-treatment complications were observed.
