Risks and complications of cochlear implant surgery
Major complications are rare. Minor complications such as temporary taste changes, mild vertigo or wound issues are uncommon and usually self-limiting.
Reported complications (rates are low overall, especially in experienced centres):
• Wound infection — usually managed with oral antibiotics.
• Temporary taste change in the side of the tongue.
• Mild vertigo for a few days.
• Facial nerve injury — very rare; modern monitoring reduces risk further.
• Cerebrospinal fluid leak — uncommon, usually managed conservatively.
• Device failure — uncommon, manufacturers provide warranty and reimplantation pathway.
Your surgeon will discuss specific risks for your case.
