Auditory perception changes after reimplantation in a child cochlear implant user

Area of Science:

• Otolaryngology
• Biomedical Engineering
• Pediatric Audiology

Background:

• A child with postlingual deafness due to meningitis received a single-channel cochlear implant.
• After three years, an internal coil failure necessitated device explantation.
• The child then received a multichannel cochlear implant in the same ear.

Purpose of the Study:

• To evaluate the feasibility and outcomes of explantation and reimplantation of cochlear implants in a pediatric patient.
• To assess speech perception abilities with different auditory devices following reimplantation.

Main Methods:

• Single case study of a child (J.L.) with profound sensorineural hearing loss.
• Detailed auditory perceptual measures were taken before and after reimplantation.
• Comparison of speech perception with a single-channel cochlear implant, vibrotactile aid, and multichannel cochlear implant.

Main Results:

• The explantation and reimplantation procedure was technically feasible.
• No adverse effects on the child's ability to use the new device were observed.
• The child demonstrated improved performance with the multichannel cochlear implant compared to the previous device.

Conclusions:

• Pediatric cochlear implant explantation and reimplantation is a viable procedure.
• Reimplantation allows for the use of more advanced cochlear implant technology.
• Successful reimplantation can lead to enhanced auditory performance in children.
