Insights
Infected cochlear implants (CI) can occur months after surgery. Prompt diagnosis and intervention are crucial for managing CI infections and ensuring successful outcomes, including re-implantation.
Area of Science:
- Otolaryngology
- Neurosurgery
- Infectious Diseases
Background:
- Cochlear implant (CI) surgery is increasingly common, leading to a rise in reported complications.
- While generally safe, CI surgery carries risks, including post-operative infections.
Abstract:
Cochlear implant (CI) surgery is relatively safe, however reports of complications and failure following cochlear implant surgery are higher nowadays due to the increasing number of patients with CI. Herein, we report a case of infected cochlear implant 10 months after surgery. A three-year-six-month-old girl underwent right cochlear implantation for bilateral profound sensorineural hearing loss. From day one until six months after the surgery, it was uneventful and the wound healed well. However, at 10 months post-surgery, she presented with a chronic discharging wound over the previous surgical site. Despite being on IV antibiotics for six weeks and daily dressing, the wound over the implant site keep discharging and eventually the implant was removed two months later. She was later re-implanted with a cochlear implant on the same side at the age of five years 10 months old. Currently, she is showing good speech improvement with the right CI. Her aided hearing threshold is at 30-40 dB at all frequencies. Early diagnosis is crucial, and the proper course of action should be taken as soon as possible if implant failure is suspected. Prior to implant surgery, any potential risk factors that could lead to implant failure should be identified and addressed appropriately to reduce the risk of an infected cochlear implant.
