Area of Science:

  • Pediatric Audiology
  • Neuroscience
  • Otolaryngology

Context:

  • Analysis of 1300 Auditory Brain-Stem Response Audiometry exams.
  • Patient cohort stratified by age, clinical presentation, risk factors, and hearing thresholds.
  • Inclusion of diverse risk factors: gestational, delivery, neonatal, genetic, congenital anomalies, infections, syndromes, and drug exposure.

Purpose:

  • To analyze hearing impairment incidence and associated risk factors in pediatric patients.
  • To evaluate the correlation between specific risk factors and hearing loss severity.
  • To assess the timing of audiological evaluations and their impact on diagnosis.

Summary:

  • Identified an 82.8% incidence of hearing impairment.
  • 54.1% of patients were diagnosed between one and three years old, indicating delayed evaluations.

  • Congenital Rubeola showed a significant 14.8% incidence and a strong correlation with increased hearing loss severity.
  • 54.0% of cases exhibited no language development.

    • Impact:

    • Highlights the high prevalence of hearing impairment in the studied pediatric population.
    • Emphasizes the critical need for early audiological screening and timely intervention.
    • Underscores Congenital Rubeola as a major modifiable risk factor for pediatric hearing loss.
