    Summary

    Congenital hypothyroidism in children can lead to significant sensorineural hearing loss. Approximately 20% of affected children experience hearing impairment, with some requiring hearing aids.

    Area of Science:

    • Pediatrics
    • Endocrinology
    • Audiology

    Background:

    • Congenital hypothyroidism (CH) is a condition affecting thyroid hormone production from birth.
    • Hearing impairment is a potential complication of CH, necessitating audiological evaluation.
    • Understanding the hearing profile in CH patients is crucial for early intervention.

    Purpose of the Study:

    • To investigate the hearing status of children diagnosed with congenital hypothyroidism.
    • To determine the prevalence and type of hearing loss in this pediatric population.
    • To assess the need for auditory rehabilitation in CH patients.

    Main Methods:

    • Studied 45 children with congenital hypothyroidism (thyroid agenesis, hypogenesis, or dyshormogenesis) under substitution therapy.
    • Hearing thresholds assessed using pure-tone audiometry or conditioned orientation reflex audiometry.
    • Excluded children with temporary secretory otitis media before assessment.

    Main Results:

    • 80% of patients (36/45) had normal auditory thresholds.
    • 20% of patients (9/45) exhibited sensorineural hearing loss.
    • 11% of patients (5/45) had significant hearing loss requiring auditory rehabilitation, with 4 using hearing aids.

    Conclusions:

    • A substantial proportion of children with congenital hypothyroidism experience persistent sensorineural hearing loss.
    • The findings align with animal studies showing developmental issues in the auditory system of congenital hypothyroid models.
    • Early audiological monitoring is essential for children with congenital hypothyroidism to detect and manage hearing deficits.
