Cerumen removal. How necessary is it to diagnose acute otitis media?
Abstract:
We evaluated the consistency and appearance of aural cerumen and the degree to which such cerumen obscured the view of the eardrum in 279 children with unilateral acute otitis media with effusion (AOME). Mechanical removal of cerumen was necessary overall in 29% of the patients. Cerumen removal was inversely proportional to age, and we found it necessary to remove such cerumen to visualize most of the eardrum in 35 (57%) of 61 infants with AOME. Some physicians believe that the heat generated from an intensely inflamed middle ear will invariably cause sticky, honey-colored cerumen to liquefy. Only 29 children (11%) in this study had aural cerumen with a soft cheesy or semiliquefied consistency.
Insights
Cerumen removal was needed in 29% of children with acute otitis media with effusion (AOME). Infants required more frequent cerumen removal for clear eardrum visualization, challenging the liquefaction theory.
Area of Science:
- Otolaryngology
- Pediatric Medicine
Background:
- Acute otitis media with effusion (AOME) is common in children.
- Eardrum visualization can be challenging due to aural cerumen.
- Physician beliefs suggest middle ear inflammation liquefies cerumen.
Purpose of the Study:
- To assess cerumen consistency and its impact on eardrum visualization in children with AOME.
- To evaluate the necessity and frequency of cerumen removal in this population.
Main Methods:
- Evaluated cerumen consistency and eardrum visibility in 279 children with unilateral AOME.
- Recorded instances requiring mechanical cerumen removal.
- Analyzed the relationship between age and cerumen removal necessity.
Main Results:
- Cerumen removal was necessary in 29% of patients.
- Cerumen removal necessity decreased with increasing age.
- In infants (≤1 year), 57% required cerumen removal for eardrum visualization.
- Only 11% of children had soft or semiliquefied cerumen, contradicting the liquefaction theory.
Conclusions:
- Aural cerumen frequently obstructs eardrum view in pediatric AOME.
- Infants are particularly prone to cerumen impaction hindering diagnosis.
- The theory of middle ear inflammation consistently liquefying cerumen is not supported by these findings.
