This study evaluated auditory functions in 218 deaf children in Turkey, finding most had profound hearing loss. Early auditory screening and comprehensive audiological assessments are crucial for effective treatment.
Area of Science:
- Audiology
- Pediatric Medicine
- Otolaryngology
Background:
- Evaluating auditory functions in children with hearing loss is critical for early intervention.
- Schools for the deaf provide a unique population for assessing auditory capabilities and disorders.
Purpose of the Study:
- To assess the auditory functions of children attending schools for the deaf in Turkey.
- To identify the prevalence of different types and degrees of hearing loss in this population.
Main Methods:
- A cohort of 218 children from schools for the deaf underwent audiological evaluations.
- Methods included otoscopy, immittance audiometry, acoustic reflex testing, pure tone audiometry, otoacoustic emissions, and auditory brainstem response testing.
Main Results:
- The mean age of hearing loss identification was 48 months.
- Profound hearing loss was prevalent, affecting 86.69% on pure tone audiometry and 88.07% on auditory brainstem response testing.
- Impacted wax was the most common otoscopic finding (22.47%).
Conclusions:
- Early auditory screening is essential for identifying at-risk children.
- Comprehensive audiological assessments, including pure tone audiometry, otoacoustic emissions, and auditory brainstem response, are vital for successful treatment planning.
- Not all hearing disorders are detectable by all audiometric tests alone.
