Population-based, age-specific myringotomy with tympanostomy tube insertion rates in Calgary, Canada

Area of Science:

• Otolaryngology
• Pediatric Health
• Health Services Research

Background:

• Myringotomy with tympanostomy tube insertion is a common pediatric surgical procedure.
• Understanding population-based procedural rates is crucial for healthcare planning and resource allocation.
• Previous data on the incidence of this procedure in Calgary was limited.

Purpose of the Study:

• To determine the population-based rates of myringotomy with tympanostomy tube insertions in Calgary.
• To analyze age-specific procedural rates for children aged 0-15 years.
• To identify the proportion of young children (<5 years) requiring repeated procedures.

Main Methods:

• Retrospective analysis of administrative healthcare databases in Calgary.
• Data collection spanned from 1997 to 2000.
• Calculation of age-specific incidence rates per 1,000 people per year.

Main Results:

• Overall age-specific rates were 12.8 (0-11 months), 54.2 (12-23 months), and 11.1 (0-15 years) per 1,000 person-years.
• The highest incidence was observed in the 12-23 month age group.
• Approximately 7.1% of children under 5 years of age underwent repeated tympanostomy tube insertions.

Conclusions:

• Myringotomy with tympanostomy tube insertion is frequently performed in young children in Calgary.
• Toddlers represent the highest-risk group for this procedure.
• A notable percentage of young children require repeat surgeries, indicating potential for further investigation into underlying causes or management strategies.
