Aetiological factors in chronic secretory otitis in relation to age
Insights
This study found that chronic secretory otitis media affects 8.7% of children aged 2-12, with prevalence decreasing with age. Upper respiratory infections and nasal obstruction significantly increase the risk of this common childhood ear condition.
Area of Science:
- Pediatrics
- Otolaryngology
- Epidemiology
Background:
- Chronic secretory otitis media is a common pediatric ear condition.
- Understanding its prevalence and risk factors is crucial for effective management.
Purpose of the Study:
- To determine the prevalence of chronic secretory otitis media in children aged 2-12 years.
- To identify factors associated with the condition, including upper respiratory infections and nasal obstruction.
Main Methods:
- A cross-sectional study involving 5414 children aged 2-12 years.
- Data collection included medical history and physical examination.
- Statistical analysis to determine prevalence and associations.
Main Results:
- The overall prevalence of chronic otitis media was 8.7%, with specific rates for adhesive otitis (0.59%) and chronic suppurative otitis media (0.35%).
- Prevalence peaked at age 2 and decreased logarithmically with age.
- Secretory otitis media showed a significant association with upper respiratory tract infections and nasal obstruction.
Conclusions:
- Chronic secretory otitis media is prevalent in young children, with incidence declining by age 12.
- Upper respiratory infections and nasal obstruction are key risk factors.
- Further research may clarify the role of adenoids in the condition.
Abstract:
The prevelance of chronic secretory otitis media was studied in 5414 children aged 2-12 yr. The maximum incidence of the disease was at the age of 2 yr decreasing progressively to the age of 12, the results fitting a logarithmic curve. Of all the children, 8.7% had chronic otitis media, 0.59% had adhesive otitis and 0.35% chronic suppurative otitis media. The prevalence of secretory otitis was, significantly, related to infections of the upper respiratory tract and to nasal obstruction. The part played by the adenoid was more questionable. Purulent otorrhoea was more frequent in those children with secretory otitis than normal children.
