Abstract:
Myringoplasty is still the most performed otological surgery. Nevertheless, the underlay vs. overlay approaches have yet to be determined. The purpose of this study is to compare the surgical and audiological outcomes of underlay and overlay myringoplasty in perforated tympanic membrane patients. A systematic review and meta-analysis synthesizing randomized controlled trials (RCTs), which were retrieved by systematically searching of Web of Science, SCOPUS, PubMed, and Google Scholar until January 25th, 2023. RevMan version 5.4 software was used to pooled dichotomous outcomes using the risk ratio (RR) with the corresponding 95% confidence interval (CI). We registered our protocol in PROSPERO with ID: [CRD42023387432]. We included eight RCTs with 656 tympanic perforation membrane patients. Four RCTs had a low risk of overall bias, two had some concerns, and two had a high risk of bias. The underlay technique was significantly associated with a higher surgical success rate (n = 7 RCTs, RR: 1.21 with 95% CI [1.02, 1.43], P = 0.03) and audiological success rate (n = 4 RCTs, RR: 1.31 with 95% CI [1.18, 1.44], P < 0.00001). This meta-analysis underscores the potential superiority of the underlay technique in managing tympanic membrane perforations, with significant implications for surgical and audiological outcomes. However, more investigations are still necessary to confirm this result.
