Five or more ear discharge episodes in children with chronic otitis media (COM) signal potential hearing loss. This finding helps doctors identify children needing surgery to prevent permanent auditory damage.
Area of Science:
- Pediatric Otolaryngology
- Audiology
- Oto-neurology
Background:
- Chronic otitis media (COM) in children can lead to irreversible sensorineural hearing loss (SNHL).
- SNHL significantly impacts language development and academic performance in pediatric patients.
- A clear clinical threshold for surgical intervention in pediatric COM is lacking.
Purpose of the Study:
- To determine a quantitative threshold for otorrhea frequency indicating significant sensorineural hearing loss (SNHL) in pediatric COM.
- To establish objective criteria for timely surgical referral in pediatric COM cases.
- To investigate the relationship between otorrhea frequency and bone conduction (BC) threshold shifts.
Main Methods:
- Retrospective analysis of 60 pediatric patients (5-18 years) undergoing surgery for COM or cholesteatoma.
- Linear regression, Pearson's correlation, and ROC curve analyses were employed.
- Quantified the association between otorrhea frequency and BC threshold shifts at least six months postoperatively.
Main Results:
- Otorrhea frequency showed a significant correlation with BC deterioration (r=0.327, p=0.011).
- Five or more otorrhea episodes were identified as the optimal cutoff for predicting a clinically significant BC shift (≥10 dB).
- ROC analysis yielded an area under the curve of 0.712, with 75.0% sensitivity and 80.0% specificity.
Conclusions:
- Five or more otorrhea episodes serve as a critical indicator for potential cochlear injury in pediatric COM.
- This threshold offers a simple, age-independent criterion for primary care physicians and pediatricians.
- Timely surgical referral based on this criterion can prevent lifelong auditory morbidity in children.
