Complications related to cochlear implants: experience in Tehran.
OBJECTIVE
Cochlear implantation (CI) is an effective treatment for profound deaf patients. To study the cochlear implant complications in patients at Amir Aalam Hospital.


METHODS
The study population involved 177 profoundly deaf patients, implanted within the same cochlear implant center.


RESULTS
Twenty-four (13.6%) patients experienced complications. Early complications accrued in 9 (37.7%) patients within the first 24 hours. Eight (4.5%) patients had major complications including facial nerve paralysis, suture rupture and prosthesis rejection. Prosthesis rejection 6 (30%) was the most frequent major complication. Minor complications were found in 16 (9%) cases which were managed medically. Older age with CI was correlated with higher major complications.


CONCLUSIONS
In contrast to minor complications, the frequency of major complications in this cohort was higher than that published by other groups.
