What are the disadvantages and risks of cochlear implants?

ANSWER

Cochlear implant surgery is very safe, but any operation has risks. Problems can include bleeding, infections, and side effects from anesthesia. Other possible complications include:

  • Nerve damage
  • Dizziness or balance problems
  • Hearing loss
  • Ringing in your ears (tinnitus)
  • Leaks of the fluid around the brain
  • Meningitis, an infection of the membranes around the brain. It’s a rare but serious complication. Get vaccinated to lower your risk. Lastly, if the device doesn't work or gets infected, you may have to have it taken out.
