Insights
Children who had otitis media surgery before age 4, especially after age 4, faced higher risks of recurrent otitis media at age 10. Parental reports on tympanostomy tubes and adenoidectomy are reliable.
Area of Science:
- Pediatric Otolaryngology
- Epidemiology of Infectious Diseases
- Childhood Health Outcomes
Background:
- Otitis media (OM) is a common childhood infection requiring surgical intervention in some cases.
- Understanding long-term infectious susceptibility after OM surgery is crucial for pediatric health.
- Parental recall of surgical history can impact data accuracy in epidemiological studies.
Observation:
- A population-based survey of 3406 10-year-olds in Oslo, Norway, assessed OM and surgical history.
- Reliability of parental reports on OM surgery was evaluated in a subset of 2027 children.
- Surgery for otitis media was performed in 10% of the cohort, with peak ages for procedures noted.
Findings:
- Children with prior otitis media surgery had a significantly higher odds ratio (3.4) for experiencing OM at age 10.
- Surgical intervention after age 4 further increased this risk (OR 4.2).
- Parental reports showed high reliability for tympanostomy tubes (kappa=1.0) and adenoidectomy (kappa=0.9), but moderate for myringotomy (kappa=0.6).
Implications:
- Previous otitis media surgery, particularly when performed later in childhood, is linked to increased infectious susceptibility.
- Parental recall is a reliable source for tympanostomy tube and adenoidectomy history in epidemiological research.
- These findings inform clinical practice regarding the timing of OM surgical interventions and follow-up care.
Objectives:
Assess infectious susceptibility in children previously operated for otitis media and evaluate reliability of parental reported otitis media surgery in the same group of children.
Methods:
Population based, cross-sectional survey of 10-year olds in the city of Oslo, Norway studying otitis media and surgical intervention in n=3406 with reliability assessments in a subset of n=2027.
Results:
Ten percent of children had otitis media surgery. Peak age was 2.5 years for adenoidectomy and tympanostomy tubes and 3 years for myringotomy. The crude odds ratio (cOR) with 95% confidence interval (95% CI) for one or more episodes of otitis media at 10 years in children with previous otitis media surgery was 3.4 (2.7-4.4). Intervention after the child was 4 years increased the risk further, crude odds ratio 4.2 (2.9-6.1). Kappa coefficients for agreement in answers to questions on otitis media surgery performed in children between 0 and 4 years were 0.9 for adenoidectomy, 1.0 for tympanostomy tubes, and 0.6 for myringotomy.
Conclusion:
Otitis media in 10-year old children was associated with previous surgical intervention, particularly when performed after 4 years of age. Parental reports of tympanostomy tubes and adenoidectomy in early childhood were found reliable.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
