Insights
This study found that 8.2% of children had type B tympanograms, indicating a high prevalence of otitis media with effusion, a common cause of childhood hearing loss.
Area of Science:
- Pediatric Otolaryngology
- Audiology
- Public Health
Background:
- Otitis media with effusion (OME) is a prevalent childhood condition.
- OME is a leading cause of acquired hearing impairment in children.
- Prevalence rates of OME vary significantly across different populations.
Purpose of the Study:
- To determine the point prevalence of type B tympanograms.
- To establish type B tympanograms as an indicator for OME presence.
- To assess the diagnostic value of tympanometry in identifying OME.
Main Methods:
- A cross-sectional study involving 9540 children aged 1-12 years.
- Data collected from September 1997 to May 2000 across four provinces.
- Utilized otoscopic examination and Grason Stadler 30-33 audiologic assessment for tympanometry (types A, B, C1, C2).
Main Results:
- The point prevalence of type B tympanograms was 8.2%.
- The prevalence of otitis media with effusion was determined to be 7.5%.
- A strong correlation was observed between type B tympanograms and OME.
Conclusions:
- Tympanometry, specifically type B results, plays a significant role in diagnosing otitis media with effusion.
- This study highlights the utility of tympanometry in identifying OME in pediatric populations.
- Findings support the use of tympanometry as a key diagnostic tool for OME.
Objective:
Otitis media with effusion is a common disease; it is primarily a disease of children. Otitis media with effusion was found as the most common cause of hearing impairment among children. The prevalence varied in different populations. Using otoscopy and tympanometry usually gives a valuable indication of the presence of otitis media with effusion. The aim of this study is to determine the point prevalence of type B tympanogram as a diagnostic and indication of the presence of otitis media with effusion.
Methods:
This study was carried out during the period September 1997 through to May 2000. The study population consisted of 9540 children aged one year to 12 years from the 4 provinces of the country. Otoscopic examination and audiologic assessment were carried out using Grason Stadler Incorporation 30-33. The tympanograms were divided into A, B, C one, and C2 groups.
Results:
The point prevalence rate of type B tympanograms among children was 8.2%. The prevalence of otitis media with effusion was 7.5%
Conclusion:
This study indicates that tympanogram has a significant role in otis media effusion.
