[Correlation between the thresholds acquired with ASSR and sbjective thresholds in cochlear implants in prelingually...

Area of Science:

• Audiology
• Otolaryngology
• Pediatric Medicine

Background:

• Cochlear implantation is a common treatment for prelingually deaf children.
• Assessing pre-operative auditory function is crucial for predicting post-operative outcomes.
• Auditory steady-state responses (ASSR) offer objective measures of hearing thresholds.

Purpose of the Study:

• To investigate the relationship between pre-operative auditory steady-state responses (ASSR) thresholds and post-operative C-level and behavior T-level in prelingually deaf children with cochlear implants.
• To determine if pre-operative ASSR can predict the effectiveness of cochlear implants.

Main Methods:

• One hundred and twelve prelingually deaf children with Nucleus CI24R(CA) cochlear implants were included.
• Children were categorized into residual hearing and no residual hearing groups based on pre-operative ASSR.
• C-level and behavior T-level were compared between groups one year post-operation.

Main Results:

• Significant differences in C-level and behavior T-level were observed between the residual hearing and no residual hearing groups (P<0.05 or P<0.01).
• Pre-operative ASSR results were associated with post-operative auditory performance levels.

Conclusions:

• Pre-operative ASSR thresholds can effectively estimate cochlear implant outcomes in prelingually deaf children.
• ASSR provides valuable reference for surgical ear selection and managing expectations for physicians and parents.
