Summary
Cochlear implant electrode migration after head trauma is rare. Successful electrode advancement restored function in a patient two months post-injury, highlighting management options.
Area of Science:
- Otolaryngology
- Neurosurgery
- Biomedical Engineering
Background:
- Cochlear implantation is a critical treatment for severe to profound hearing loss.
- Implant complications include hard failure and, rarely, traumatic electrode migration due to head trauma.
Observation:
- A patient experienced partial cochlear implant electrode migration following a head injury.
- The migrated electrode maintained normal function despite partial displacement.
Findings:
- Successful surgical advancement of the partially migrated electrode was performed.
- This procedure was completed two months after the initial head injury.
Implications:
- This case highlights successful management of traumatic cochlear implant electrode migration.
- It underscores the importance of considering surgical intervention for displaced, functional electrodes.
