Recidivism of childhood cholesteatoma and surgical techniques: a meta-analysis study

Abstract

Abstract Background There is a debate in the literature about surgical management of childhood cholesteatoma. We aimed to conduct a meta-analysis study about the recidivism of acquired cholesteatoma in children after two primary surgical procedures, namely canal wall up (CWU) and canal wall down (CWD) mastoidectomy. Main body of the abstract A Medline search of English language literature on PubMed and Cochrane Collaboration from their dates of inception until August 2019 was conducted using the following search terms: “pediatric or child and Cholesteatoma Surgery”. Twenty-eight full-text papers fulfilled the selection criteria and were included in this meta-analysis This analysis showed an odd risk of 1.72 for recidivism of childhood cholesteatoma in single-stage canal wall up procedure relative to canal wall down procedures. The 95% confidence interval (CI) for the overall odds ratio was 1.27–2.34. The I2 statistic was 37%, representing low heterogeneity. Comparing the rate of recidivism before and after the year 2000 showed that there was still increased risk of recidivism in the canal wall up versus canal wall down mastoidectomy (the odds ratio was 1.87 and 1.57 respectively). Short conclusion Single-stage canal wall up mastoidectomy was significantly associated with a higher risk of cholesteatoma recidivism compared to canal wall down technique in children with acquired cholesteatoma
