Comparison of Adult and Pediatric Cochlear Implant Wound Complications: A Meta‐Analysis

alexandrossfakianakis shared this article with you from Inoreader Comparison of Adult and Pediatric Cochlear Implant Wound Complications: A Meta‐Analysis via The Laryngoscope The objective of this study is to compare age-related differences in wound complications following cochlear implantation (CI). CI wound complication rates reported in the literature are low; however, adults have a higher risk of these complications than pediatric patients. The reported complication rate in elderly adults is low. Objective To compare age-related differences in wound complications following cochlear implantation (CI). Methods We performed a systematic review of PubMed, Cochrane Database, and Web of Science databases to identify original research evaluating the patient-level factors (demographics and medical history) associated with wound complications following CI. Outcomes were expressed as relative risk (RR) with 95% confidence intervals using the inverse variance method. Studies without comparison groups were described qualitatively. Results Thirty-eight studies representing 21,838 cochlear implantations were included. The rate of wound complications ranges from 0% to 22%. Patient age (adult versus pediatric) was the only factor with comparison groups appropriate for meta-analysis. The 10 studies (n = 9547 CI's) included in the meta-analysis demonstrated that adults had a higher incidence of overall wound complications (2.94%) than in children (2.44%) (RR 1.31, 95% CI 1.01–1.69). Adults had a higher incidence of general/unclassified wound complications (2.07%) than in children (1.34%) (RR 1.68, 95% CI 1.12–2.52). There was no difference between adults and children for specific complications such as hematoma, infection, or seroma. Elderly patients (over age 75) have wound complication rates that range from 1% to 4%. No studies contained comparison groups regarding other patient-level factors and CI wound complications. Conclusion CI wound complication rates reported in the literature are low; however, adults have a higher risk of these complications than pediatric patients. The reported complication rate in elderly adults is low. There is a gap in CI research in consistently reporting wound complications and rigorous research investigating the impact of patient-level factors and wound complications.
