Abstract
Objective Compare intraoperative and postoperative outcomes of endoscopic and microscopic stapes surgery to provide objective evidence on whether the former is a better alternative than the latter. Methods We performed a systematic review and meta‐analysis for studies that compared endoscopic stapes surgery with microscopic stapes surgery. Only studies that met predetermined criteria were selected and assessed for bias and quality. Primary outcomes were postoperative air–bone gap (ABG) and chorda tympani nerve injury. Secondary outcomes were average operating time, tympanic membrane (TM) perforation, and postoperative taste disturbance, pain, and dizziness. We calculated pooled odds ratios (ORs) with 95% confidence intervals (CIs) for dichotomous outcomes and weighted mean difference (WMD) with 95% CI for continuous outcomes. A confidence interval starting above 1.0 was considered as statistically significant. I2 and χ2 tests were used to quantify statistical heterogeneity. We used funnel plots to look for publication bias and performed a sensitivity analysis. Results Six nonrandomized cohort studies were eligible. The primary outcomes were ABG < 10 dB: OR = 1.80 (95% CI: 0.96 to 3.38), ABG = 11 dB to 20 dB: OR = 1.49 (95% CI: 0.76 to 2.93), ABG > 20 dB: OR = 2.51 (95% CI: 0.77 to 8.22), and chorda tympani injury: OR = 3.51 (95% CI: 1.55 to 7.93). Secondary outcomes were taste: OR = 2.36 (95% CI: 1.01 to 5.51), average operation time: WMD = 0.14 (95% CI: −11.69 to 11.98), TM perforation: OR = 1.70 (95% CI: 0.44 to 6.58); pain: OR = 0.84 (95% CI: 0.36 to 1.96), and dizziness: OR = 2.15 (95% CI: 0.94 to 4.89). Conclusions Endoscopic stapes surgery is a valid alternative to the microscope. Level of Evidence 2a Laryngoscope, 2019Keywords
