Background:
Cochlear implant surgery has a low morbidity and mortality. Postoperative complications 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. Children 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 children and adolescents, youth and adults are 33.81 %; and 8.73 % are seniors. The complication rate is 12 % (n = 33), 6.91 % for women and 5.09 % for men. There are more complications among 19 to 60 years old. Minor complications account for 7.6 %: local infection (n = 9), delayed transient facial palsy (n = 7), vertigo (n = 3) and tinnitus (n = 2). These are prevalent in children and adults. Major complications are 4.36 %: postoperative hematoma (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 meningitis 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.
Insights
Cochlear implantation surgery is safe, with a 12% complication rate. Most complications were minor, such as local infection or temporary facial palsy, with major complications like hematoma or extrusion being less common.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Device Technology
Background:
- Cochlear implant surgery, while generally safe with low mortality, can lead to minor or major postoperative complications.
- Minor complications are managed conservatively, whereas major complications may necessitate reoperation or device removal.
Purpose of the Study:
- To evaluate the incidence and types of complications following cochlear implantation in a specific patient cohort.
- To compare these complication rates with international and Latin American data.
Main Methods:
- A retrospective analysis of 275 cochlear implant surgeries performed between December 2005 and December 2013.
- Inclusion criteria encompassed patients aged 11 months to 82 years, with data on demographics, surgery type, and postoperative complications collected over a 20-month follow-up period.
Main Results:
- The overall complication rate was 12% (n=33), with a higher incidence in women (6.91%) and adults aged 19-60 years.
- Minor complications (7.6%) included local infection, transient facial palsy, vertigo, and tinnitus, predominantly in children and adults.
- Major complications (4.36%) such as hematoma, extrusion, and inadequate electrode placement were more common in adults aged 19-60. No deaths or meningitis cases were reported.
Conclusions:
- Cochlear implantation demonstrates a low incidence of complications, aligning with existing literature.
- These findings represent the sole national-level report, offering valuable comparative data for Latin American series.
