Basics
Is a cochlear implant safe?
Cochlear implant surgery is well-established with low complication rates. Like any surgery, there are risks — but in experienced hands, outcomes are consistently positive.
Cochlear implant surgery has been performed worldwide since the 1980s with extensive long-term follow-up data. In experienced centres, serious complication rates are below 2%. Common minor issues — temporary taste changes, mild dizziness, scar tenderness — usually resolve within weeks.
Device reliability has also improved substantially. Modern implants from Cochlear, MED-EL and Advanced Bionics report cumulative survival rates of 95%+ at 10 years. Pre-surgical evaluation includes medical clearance, imaging (CT/MRI), audiology and counselling so that risks specific to each patient are discussed in advance.
A child or adult who is medically fit for a routine general anaesthesia is generally fit for a cochlear implant.
Frequently asked questions
Is CI brain surgery?
No. The surgery is on the mastoid bone and cochlea — not the brain.
How long is recovery?
Most patients are discharged within 1–2 days and back to normal activity in 1–2 weeks.
