Systematic Review on Surgical Outcomes and Hearing Preservation for Cochlear Implantation in Children and Adults
Abstract
The mastoidectomy with facial recess approach (MFRA) is considered the reference standard for cochlear implantation. The suprameatal approach (SMA) was developed more recently and does not require mastoidectomy, which could influence postoperative outcomes. We aim to identify the optimal operative approach for cochlear implantation based on postoperative complications and hearing preservation in children and adults. PubMed, EMBASE, Scopus, and Google Scholar. Studies comparing MFRA and SMA in children and adults were eligible for inclusion. Original reports with moderate relevance and validity were included. Relevance and validity were assessed with a self-modified critical appraisal tool. This review was reported in accordance to PRISMA guidelines. We retrieved 294 citations. Only retrospective nonrandomized studies were identified (level III evidence). Six articles were selected for full-text inclusion and 4 articles for data extraction. No article found a significant difference between MFRA and SMA with respect to postoperative complications in children and adults. One study found a significantly (P < .023) higher pediatric MFRA mastoiditis rate; however, meta-analysis did not indicate an overall effect. Hearing preservation...Continue Reading
