Summary
The prevalence of severe to profound sensorineural hearing loss in Saudi children is high. This study highlights the need for increased audiology services and cochlear implant consideration for affected children.
Area of Science:
- Audiology
- Pediatric Health
- Public Health
Background:
- Sensorineural hearing loss (SNHL) in children poses significant challenges to development and quality of life.
- Understanding the prevalence of SNHL in specific populations is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of SNHL in Saudi children.
- To identify children with severe to profound SNHL requiring cochlear implants.
Main Methods:
- A comprehensive survey screened 9540 Saudi children across four provinces.
- Methods included questionnaires, clinical examinations, and audiological assessments.
- Advanced diagnostics like CT scans and auditory brainstem response were used for complex cases.
Main Results:
- Overall hearing impairment prevalence was 13%.
- Sensorineural hearing loss affected 1.5% (142 children).
- Severe to profound SNHL (76-100 dB loss) was found in 0.7% (68 children), predominantly bilateral.
Conclusions:
- The prevalence of severe to profound SNHL in Saudi Arabia is higher than in developed nations.
- Cochlear implantation is a viable option for severe to profound SNHL, after hearing aid trials.
- There is a critical need for more accessible hearing and speech centers across Saudi provinces.
