“…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). In this study, the author concluded that such complications are commonly associated to the type of cochlear implant 6 . American Cochlear Implant Centers reported an incidence of major and minor complications of 8% and 4.3%, respectively, in a sample of 2,751 implanted patients 3 .…”

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.

“…The use of cochlear implant (CI) in children provides important benefits for the development of listening and communication skills and allows their progress in school and, later on, in the ability to obtain, maintain, and perform a professional occupation. As a result, many children in the world have been receiving the CI (1,2) .…”

“…Studies report a low overall rate (about 1%) of electrode migration 15 , but some authors have found that it is a leading cause of reimplantation, second only to device failure 20 , 23 . A review of 3,773 cases in Latin America 24 showed that full migration occurred in 13 cases (0.35%), most of them associated with ceramic implants (ClarionT, MED-ELT, 3MT).…”

The combined approach technique (CAT) is a variation of the classical the mastoidectomyposterior tympanotomy technique (MPTA) that combines a transcanal approach to cochleostomy with a reduced posterior tympanotomy for insertion of electrodes. Aim:To compare and evaluate long-term safety and effectiveness outcomes obtained with the CAT and with MPTA approach in patients submitted to cochlear implant (CI) surgery. Design: series study. Methods:Patients who underwent CI using CAT or MPTA at a Brazilian center were followed in a cohort study. Main outcomes were complications,audiometric performance and radiological evaluation of electrode position.Results: Fourty-four patients were implanted using CAT and 31 MPTA. There were no cases of facial nerve paralysis, mastoiditis, cholesteatoma or cerebrospinal fluid leaks after 3.4±1.0 years. Radiological evaluation of electrode position revealed that the median number of electrodes outside the cochlea was 0 in CAT and 3 in MPTA groups (p < 0.001). There were no differences between both surgical approaches in terms of mean pure-tone thresholds with CI at all frequencies. Conclusion:Long-term follow-up data showed that the transcanal route to cochleostomy, combined with a reduced posterior tympanotomy, is a safe alternative approach in cochlear implant surgery, with no related major complications and fewer cases of electrode migration when compared with the MPTA. These findings encourage the use of the transcanal route to cochleostomy as an alternative approach option. Braz J Otorhinolaryngol. 2012;78(2):118-23. ORIGINAL ARTICLE BJORL
