Objectives: To investigate complications of cochlear implantation for prevention and therapy.
Study Design: Retrospective study at a tertiary referral center.
Methods: The patients (n=416) who received cochlear implants in our department between 2000 and 2010 were followed up (range, 3 months to 10 years). The complications were identified as “minor” or “major”. All complications were systematically reviewed, and their causes were analyzed for prevention and therapy.
Results: There were a total of 29 complications (7%). The minor were 23 cases (5.5%), including postoperative subcutaneous hematoma in 13 cases, acute otitis media in 2 cases, postoperative wound infection in 2 cases, delayed facial paralysis in 1 case, clonic facial spasm in 1 case, and severe dizziness in 4 cases. The major were 6 cases (1.5%), including cerebrospinal fluid leakage in 2 cases, implant-related infection and extrusion in 1 case, tympanic membrane perforation induced electrode exposed in 1 case, implantation failure due to cochlear ossification in 1 case, and magnet displacement in 1 case.
Conclusions: Cochlear implantation is a safe and reliable operation; but it is still a serious problem to lower the incidence of complications.
