Summary
Early cochlear implantation (CI) in children with prelingual hearing loss significantly improves auditory performance and speech intelligibility. This study assessed CI outcomes in Iraq, highlighting the importance of implantation age for better results.
Area of Science:
- Otolaryngology
- Pediatric Audiology
- Speech-Language Pathology
Background:
- Cochlear implantation (CI) is a key intervention for prelingual hearing loss.
- Post-implantation rehabilitation is crucial for language development in children.
- This study evaluates CI outcomes in Erbil, Iraq, comparing them globally.
Purpose of the Study:
- To assess hearing outcomes of cochlear implants performed by a single surgeon.
- To compare these outcomes with international CI center results.
- To identify factors influencing auditory performance and speech intelligibility.
Main Methods:
- Prospective study of 161 patients with prelingual hearing loss undergoing CI.
- Data collected: age at implantation, prior hearing aid use, parental education, rehabilitation duration.
- Auditory performance (CAP score) and speech intelligibility (SIR) assessed at 6 and 12 months post-surgery.
Main Results:
- Implantation age significantly correlated with Categories of Auditory Performance (CAP) scores at 6 and 12 months (p=0.001).
- Speech Intelligibility Rating (SIR) was also significantly associated with implantation age (p=0.001).
Conclusions:
- Younger age at cochlear implantation is linked to better auditory and speech outcomes.
- This finding emphasizes the critical role of early intervention in pediatric hearing loss.
- Results provide benchmarks for CI centers in the Kurdistan region and worldwide.
