| Abstract | ||
| Background: Revision cochlear implant surgeries are uncommon but they represent a challenging issue for surgeons. Thoughtful preparation and evaluation of patients with proper counseling are mandatory. Objectives: To identify the rate of revision surgeries and re-implantations, evaluate the causes, and analysis of clinical and operative findings. Patients & Methods: A retrospective study including 46 cases underwent revision surgeries out of 1144 patients had cochlear implantation in the department of otolaryngology/Baghdad Medical City in the period from March 2009 to November 2019. The data were collected from 3 statistical record sources (the otolaryngology department records, operative theatre records, and hospital’s main statistic department). Results: Revision cochlear implantation ratio was 4%. It was found that most of the cases were from pediatric age group (98% of cases with mean age of 6.77 years) with no difference between males and females (male to female ratio was 1.1:1). The most common causes for revision surgeries were non-device related (63%) while device related causes counted (37%). Re-implantation rate was (24%). Conclusion: Revision cochlear implant surgeries in our center were within lower limits of the universal revision rates. Most commonly encountered cause for revision was wound infection with/without dehiscence followed by hard device failure. No significant complications recorded per and post operatively. | ||
