Insights
Cochlear implantation (CI) is safe, with a 10.1% complication rate. Major complications requiring reimplantation occurred in 2.75% of cases, with device failure being the most common cause. Pediatric patients experienced higher complication rates than adults.
Area of Science:
- Otolaryngology
- Neurosurgery
- Biomedical Engineering
Background:
- Cochlear implantation (CI) is a vital auditory prosthetic surgery.
- Understanding complication rates and types is crucial for patient outcomes.
Purpose of the Study:
- To determine short- and long-term complications following cochlear implantation (CI).
- To discuss the management and prevention strategies for CI complications.
Main Methods:
- Retrospective analysis of 1452 cochlear implantation procedures (pediatric and adult) from March 2000 to September 2019.
- Complications classified as major (requiring/not requiring reimplantation) and minor.
- Minimum follow-up of three months, maximum of 19 years.
Main Results:
- A total of 148 complications (10.1%) were observed.
- Major complications occurred in 4.75% (40 requiring reimplantation), with device failure as the leading cause (1.99%).
- Minor complications occurred in 5.44%, with hematoma being most frequent. Pediatric complication rates (6.68%) were higher than adult rates (3.51%).
Conclusions:
- Cochlear implantation (CI) is a safe and successful procedure with low major complication rates.
- Effective management and prevention of complications are essential for optimal CI outcomes.
Objective:
The aim of this study was to determine the short- and long-term complications after cochlear implantation (CI) procedures and to discuss the management and prevention of these complications.
Methods:
The study included a total of 1452 pediatric and adult cochlear implantation procedures performed in our clinic from March 2000 through September 2019. Of the 1452 implantations, 1201 were performed in children and 156 in adults. The minimum follow-up period was three months and maximum was 19 years. The mean age of the patients was 6.7±3.9 years (range, 10 months-69 years) at the time of their respective procedures. Complications were classified as major complications requiring reimplantation, major complications not requiring reimplantation and minor complications. All postoperative complications and treatment methods were examined.
Results:
A total of 148 (10.1%) complications were observed in the 1452 cochlear implants. Of these, 69 (4.75%) were major and 79 (5.44%) were minor complications. While 40 (2.75%) of the major complications required reimplantation, 29 (1.99%) did not. The most common cause of major complications leading to reimplantation was device failure (29 patients, 1.99%). The most common cause of minor complications was hematoma (21 patients). Total complication rates (6.68%) were significantly higher in children than in adults (3.51%) (p=0.00).
Conclusion:
Our 19 years of clinical experience has shown that CI is a successful and safe procedure that can be performed with low major complication rates. It is important to know the possible complications and to manage them correctly.
