Otitis media surgery: large variability between Finland and Norway

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Public Health

Background:

• Otitis media is a common childhood infection requiring medical attention.
• Surgical interventions for otitis media include tympanostomy tube insertion and adenoidectomy.
• International variations in surgical practice for otitis media are not well-documented.

Purpose of the Study:

• To compare surgical treatment rates for paediatric otitis media between Finland and Norway.
• To identify demographic and regional factors influencing surgery incidence.
• To evaluate the consistency of otitis media surgical care across similar nations.

Main Methods:

• A registry-based cross-sectional study utilizing complete surgical data from 2002.
• Inclusion of 21,811 Finnish and Norwegian children aged 0-16 years.
• Analysis of total surgery rates, procedure-specific rates (adenoidectomy, tympanostomy tubes), and regional variations.

Main Results:

• Finland exhibited higher overall otitis media surgery rates (146.5/10,000) compared to Norway (82.5/10,000).
• Adenoidectomies were four times more common in Finland; tympanostomy tube insertion rates were 2-3 times higher.
• Surgery rates were highest in the 0-2 year age group and in sparsely populated regions.

Conclusions:

• Significant disparities in otitis media surgery incidence between Finland and Norway raise questions about equitable treatment.
• Current guidelines may not ensure uniform care for similarly affected children.
• Challenges exist in providing standardized recommendations for the timing and type of otitis media surgery.
