RESUMEN
Cochlear implant, which used in patients with profound hearing loss, may followed by some major or minor complications. These complications depend on age of patient, kind of device, kind of incision, surgical technique and surgeon's skill. Major complications mostly need surgical intervention for treatment and, may persist for long time. Minor complications need medical treatment and don't need surgical intervention. In this descriptive study between 2004-2007, 100 patients subjected to cochlear implantation were evaluated for post operative complications. Overall complication rate was 14%. We had 4 major complications, including 2 device failure, one misplaced electrode and one cases with major hematoma. These complications managed successfully by surgical intervention or reimplantation. Facial nerve damage or wound breakdown were not seen in these patients. Minor complications including small hematoma, edema, wound infection, dizziness were seen in 10 cases that managed medically. In the recent years complications of cochlear implantation are reduced with increasing surgeon's skill, new surgical methods and development in device technology
