OBJECTIVE This meta-analysis is aimed to review and analyze all available data of intraoperative and postoperative results of endoscopic and microscopic stapes surgery. METHODS According to the PRISMA statements checklist, this systematic review and meta-analysis were designed. Data were extracted from public databases, such as PubMed, Cochrane, Web of Science, and more. The quality of studies was evaluated using the MINORS scale. Odds ratios (ORs) and 95% CIs were estimated for binary outcome data, while the mean differences and 95% CIs were estimated for continuous data. I2 and χ2 tests were used to quantify statistical heterogeneity. If more than ten studies were included in each analysis, funnel plot would be performed to analysis publication bias. RESULTS Twelve studies with 620 patients were included in this meta-analysis. Primary outcomes collected in this meta-analysis included average postoperative auditory gain (APAG), postoperative air-bone gap (ABG), the rate of chorda tympani handling and bone curettage, which all showed a statistically significant difference in favor of endoscopy. While only secondary outcomes about postoperative pain and dysgeusia demonstrated a significantly reduced incidence. Furthermore, there was not any statistically significant difference on postoperative dizziness and average operative time between endoscopy and microscopy. CONCLUSION Although there is a need for high-quality pooled data in the future, a consistently superior effect of the endoscopic group was still shown in terms of total effectiveness, when compared to the microscopic group. We have reasons to support the application of endoscopy in stapes surgery. The future of ESS, we believe, is blazing bright.
