Redness, soreness, and swelling at the site of a cochlear implant years after surgery can indicate several issues. It may be due to an infection, skin irritation, or a reaction to the implant itself. In rare cases, it could signal an underlying problem with the device, such as migration or malfunction. Immediate medical attention is crucial to diagnose and address the issue promptly. An audiologist or ENT specialist can provide a thorough examination and appropriate treatment to prevent complications.
