Longitudinal Cochlear Implant Use in Pediatric Patients With Unilateral Hearing Loss

Area of Science:

• Audiology
• Pediatric Otolaryngology
• Biomedical Engineering

Background:

• Unilateral hearing loss (UHL) in children presents unique challenges for auditory development.
• Cochlear implant (CI) technology offers a potential solution for profound hearing loss.
• Understanding CI usage patterns in pediatric UHL is crucial for optimizing outcomes.

Purpose of the Study:

• To analyze longitudinal cochlear implant (CI) usage in children with unilateral hearing loss (UHL).
• To assess the influence of implantation age and deafness duration on CI device use.
• To identify predictors of sustained CI device adoption in pediatric populations.

Main Methods:

• Retrospective cohort study design.
• Data collected from two tertiary care centers.
• Included pediatric CI recipients with UHL implanted between 2018-2024.
• Datalogging analyzed at 3, 6, 12, 18, and 24 months postactivation.
• Usage categorized as regular (>6h/day) or moderate (>4h/day).

Main Results:

• High initial CI usage observed: 81% regular users, 83% moderate users at 3 months.
• Usage remained stable over 24 months, with 64% regular and 82% moderate users.
• Mean daily usage showed a slight decline from 8.2h to 6.8h.
• No correlation found between age at implantation or deafness duration and usage changes.
• Early usage patterns (at 6 months) predicted long-term device adoption.

Conclusions:

• Children with UHL demonstrate high and sustained cochlear implant (CI) usage up to 24 months.
• A small daily decrease in CI usage was observed over time.
• Initial CI usage patterns are indicative of long-term device adherence in pediatric UHL.
• Cochlear implantation is a viable option for children with UHL.
