Cochlear implantations in Jordan: Retrospective analysis of post-operative complications

Abstract

Aims: This study aims to carry out a retrospective analysis of demographic information and post-operative complications with special emphasis on complications related to the soft tissue over the implanted device in patients who underwent cochlear implantation. Settings and Design: Retrospective study. Patients and Methods: We conducted a retrospective review of 840 patients who had cochlear implants at our centre during the period between March 2010 and November 2020. The patients' demographic details and complications related to the soft tissue over the implanted device were analysed. Statistical Analysis Used: SPSS software version 12. Results: In total, 380 (45.2%) patients were male and 460 (54.8%) were female. The age of patients at the time of surgery ranged between 7 months and 68 years and the mean age was 4.64 ± 2.91 years. The majority of patients underwent unilateral cochlear implantation (837 patients), with only three patients receiving a bilateral implant. There were a total of 19 implanted patients who developed complications related to the soft tissue around the implanted device, with an incidence rate of 2.3%. Haematoma was the most commonly encountered complication and other complications were: seroma, wound infection, abscess formation and flap necrosis. Conclusions: Cochlear implantation is considered to be a reliable and safe surgical procedure for the rehabilitation of deaf patients. Complications can be avoided by proper patient preparation, appropriate incision and flap design, rigorous surgical techniques and periodic post-operative follow-up to detect and manage any complications early.
