“…In most of the cases the procedure is technically safe and the audiologic results are satisfactory 5 . Of the thirteen patients who had major complications, the reimplant surgery was done in 4; and from these, 2 were because of device failure and 2 were because of infection.…”

“…Major complications involve meningitis, flap necrosis, device failure, electrode extrusion, facial nerve paralysis and others; while the minor complications involve facial nerve stimulation, electrode migration, vertigo, tinnitus, and others. The major complications which require surgery review and, especially those associated with device insertion are not common 5 . In a study carried out in Latin America involving 40 cochlear implant centers in 10 countries, with a sample of 3,768 implanted patients, there were 193 postoperative complications (5.1%), and the major causes were: spontaneous system failure (86 cases), skin inflammation caused by the magnet (35 cases) and infection (26 cases).…”

Cochl ear implant surgery is regarded as safe for the auditory rehabilitation of individuals suffering from profound/severe hearing loss. Complications may arise from the surgery. The complications of implant cochlear surgery reflect the operation complexity, the skill of the surgical team and the inherent risks of the procedure itself. Aim:To establish and discuss the postoperative complications in implanted patients from the Cochlear Implant Program of Rio Grande do Norte -Brazil. Study design: Retrospective analysis. Materials and methods: This paper discusses the clinical records of 250 patients implanted betweenAugust 2000 to December 2008. All patients were implanted by the same surgeon. The postoperative complications were classified in minor as those that resolved with minimal or no treatment and major as those requiring additional surgery or hospitalization.Results: In our sample, 33 patients (13.2%) had postoperative complications. Minor complications affected 20 cases (8.0%), while major complications occurred in 13 cases (5.2%). Hematomas, device failures and infections had the highest clinical relevance. Conclusion:This review reinstates the safety of the surgical procedure in relation to the possible occurrence of postoperative complications and emphasizes the need for continuous surgeon education and training.

To date, the rehabilitation of deaf patients with a multichannel cochlear implant has been established as a worldwide accepted method. In case of normal temporal bone anatomy the surgical procedure is standardized and offers few problems. Due to restrictive preoperative patient selection, the incidence of postoperative complications is rather low and is usually flap related.'-5 The percentage of so-called "major complications" which require surgical revision is estimated as low as 7.4%.3 To reduce the surgical risk a sufficient amount of experience in regard to the special type of implant is required. The flap design should be thoroughly planned, the posterior tympanotomy carefully performed and the electrode array gently inserted after an adequate cochleostomy. The importance of a reliable device fixation is emphasized in order to prevent migration.3,6

“…Although the prevalence of complications in our sample is higher than those from most studies in the literature, we believe this can be explained by the fact that we operate cases of higher complexity, with cochlear ossification and inner ear malformation [8][9][10][11][12][13][14][15][16] . Moreover, our clinic is a center for the training of ear surgeons, with a complementary specialization program, in which trainee surgeons participate actively in the cochlear implant surgeries.…”

Cochl ear implantation is a safe and reliable method for auditory restoration in patients with severe to profound hearing loss. Objective:To describe the surgical complications of cochlear implantation. Materials and Methods:Information from 591 consecutive multichannel cochlear implant surgeries were retrospectively analyzed. All patients were followed-up for at least one year. Forty-one patients were excluded because of missing data, follow-up loss or middle fossa approach.Results: Of 550 cochlear implantation analyzed, 341 were performed in children or adolescents, and 209 in adults. The mean hearing loss time was 6.3 ± 6.7 years for prelingual loss and 12.1 ± 11.6 years for postlingual. Mean follow-up was 3.9 ± 2.8 years. Major complications occurred in 8.9% and minor in 7.8%. Problems during electrode insertion (3.8%) were the most frequent major complication followed by flap dehiscence (1.4%). Temporary facial palsy (2.2%), canal-wall lesion (2.2%) and tympanic membrane lesion (1.8%) were the more frequent minor complications. No death occurred. Conclusion:There was a low rate of surgical complications, most of them been successfully managed. These results confirm that cochlear implant is a safe surgery and most surgical complications can be managed with conservative measures or minimal intervention.
