BACKGROUND: Cochlear implant surgery has a low morbidity and mortality. @entity260 can be minor and major. Minor complications require conservative management; major complications require reoperation or implant removal. The aim is to determine our complications and compare them with international and Latin American series. METHODS: 275 operated cases were retrospectively analyzed from December 2005 to December 2013. @entity1 and adults between 11 months to 82 years old are included. Demographic data, unilateral or bilateral placement, type of surgery and postoperative complications were evaluated. The follow-up was made for 20 months. RESULTS: The 57.46 % are @entity1 and adolescents, youth and adults are 33.81 %; and 8.73 % are seniors. The complication rate is 12 % (n = 33), 6.91 % for @entity1 and 5.09 % for @entity1 . There are more complications among 19 to 60 years old. Minor complications account for 7.6 %: local infection (n = 9), delayed transient @entity3541 (n = 7), vertigo (n = 3) and @entity392 (n = 2). These are prevalent in @entity1 and adults. Major complications are 4.36 %: postoperative @entity1410 (n = 8), extrusions (n = 2) and inadequate electrode placement (n = 2). These predominate in adults among 19 to 60 years. No deaths or cases of @entity693 occurred. CONCLUSIONS: Cochlear implantation has a low incidence of complications. Our results, the only reported at the national level, are comparable with those mentioned in literature.
