Cochlear implantation (CI) surgery is the standard of care treatment for pediatric patients diagnosed with severe-to-profound sensorineural hearing loss. There is compelling evidence that supports the use of CIs to improve hearing, language comprehension, and speech development significantly in children of all ages. While the operation is considered relatively safe, invasive procedures involving the skull can put patients at risk of adverse events.

This study aims to help pediatric otolaryngologists identify high risk patients and take preventative measures to ensure minimal complications.

The specific objectives include the following:

1) To determine the incidence of postoperative complications in pediatric patients undergoing CI surgery.

2) To identify the risk factors associated with postoperative complications in pediatric CI surgery

3) To perform a sub-analysis of complication rates among different pediatric age cohorts.

A full-text retrospective chart review was conducted for all pediatric patients that underwent CI surgery at Children’s Hospital of Michigan between August 2016 and June 2021. This cohort study included 72 patients that were presented to this urban pediatric surgery unit. Each patient's comorbidities and complications were then classified as a qualitative variable and SPSS was used to investigate the statistical significance between these variables and demographics such as age cohorts, and postoperative complication risk was calculated using Pearson Chi Squared testing. As surgical techniques, medical devices, and patient guidelines continue to evolve, new data is necessary to understand how complication rates change over time. Pediatric otolaryngologists must be knowledgeable about evidence-based risk factors and complication rates related to CI surgery.
