BACKGROUND: Binaural hearing is crucial for spatial auditory perception, including sound localization. Cochlear implants (CIs) are commonly used in children with congenital deafness to support binaural auditory development, but the extent to which they facilitate effective localization remains unclear.
OBJECTIVE: This study evaluates the impact of CIs on binaural functional auditory development and sound localization in children with congenital deafness, considering factors such as age at implantation, hearing experience, and CI laterality.
METHODS: Thirty-eight CI-assisted children (aged 4-9 years) underwent directional hearing assessments using the "Erfassung des Richtungshörens bei Kindern (ERKI)" device. Localization accuracy was analyzed across various noise stimuli, and correlations with audiometric parameters and CI history were examined.
RESULTS: Localization accuracy improved with age and CI experience. Bilateral CI users outperformed unilateral users, particularly with pulse pink noise stimuli. The use of SmartSound iQ with SCAN technology enhanced localization, especially in younger children.
CONCLUSION: CIs support binaural functional auditory development in children with congenital deafness, with localization skills improving over time. Bilateral implantation and early intervention may further enhance outcomes, warranting continued research.
