Loh Eunice D. Kwa The Laryngoscope ObjectiveThe efficacy of the transcanal endoscopic approach in tympanoplasty, cholesteatoma removal, and stapedotomy is detailed. This study reviews evidence on the feasibility of endoscopic ossiculoplasty as a suitable alternative to traditional microscopic ossiculoplasty.Data SourcesPubMed, Embase, and Cochrane Library were searched from inception to 19 June 2024 for articles comparing endoscopic and microscopic ossicular chain reconstruction.Review MethodsThis systematic review was conducted in accordance with PRISMA guidelines. The primary outcomes assessed include air bone gap closure, pre‐operative and post‐operative air bone gap, pure tone audiometry, and word recognition scores. The secondary outcomes include operation time, surgical success, and surgical complications. These outcomes between microscopic and endoscopic techniques were pooled and compared as mean differences using a random‐effects model. The Risk of Bias in Non‐Randomized Studies of Interventions (ROBINS‐I) and Cochrane Risk‐of‐Bias Tool for Randomized Trials (RoB2) scale were adopted to assess for study bias in observational studies and randomized controlled trials, respectively.ResultsThis study included five studies comprising 504 patients. While endoscopic ossiculoplasty had shorter operating durations (95% CI −42.97 to −1.57), it conferred comparable air bone gap closure (95% CI −0.34 to 3.76), post‐operative pure tone audiogram (95% CI 10.97–18.77), and surgical success. Additional qualitative strengths identified in endoscopic ear surgery include improvements in visualization, decreased need for supplemental incisions, excellent ergonomics, and reduced post‐operative pain.ConclusionOverall, endoscopic ossiculoplasty may confer comparable audiological outcomes to microscopic ossiculoplasty and may serve as a reasonable alternative surgical approach.
