Background The increasing prevalence of virtual reality simulation in temporal bone surgery warrants an investigation to assess training effectiveness. Objectives To determine if temporal bone simulator use improves mastoidectomy performance. Data Sources Ovid Medline, Embase, and PubMed databases were systematically searched per the PRISMA guidelines. Review Methods Inclusion criteria were peer-reviewed publications that utilized quantitative data of mastoidectomy performance following the use of a temporal bone simulator. The search was restricted to human studies published in English. Studies were excluded if they were in non-peer-reviewed format, were descriptive in nature, or failed to provide surgical performance outcomes. Meta-analysis calculations were then performed. Results A meta-analysis based on the random-effects model revealed an improvement in overall mastoidectomy performance following training on the temporal bone simulator. A standardized mean difference of 0.87 (95% CI, 0.38-1.35) was generated in the setting of a heterogeneous study population ( I = 64.3%, P < .006). Conclusion In the context of a diverse population of virtual reality simulation temporal bone surgery studies, meta-analysis calculations demonstrate an improvement in trainee mastoidectomy performance with virtual simulation training.
颞骨手术中虚拟现实模拟的日益普及促使人们进行一项调查以评估培训效果。目的：确定使用颞骨模拟器是否能提高乳突切除术的操作水平。数据来源：按照PRISMA指南系统检索了Ovid Medline、Embase和PubMed数据库。综述方法：纳入标准为使用颞骨模拟器后对乳突切除术操作进行定量数据研究的同行评议出版物。检索仅限于以英文发表的人体研究。如果研究为非同行评议格式、本质上是描述性的或未提供手术操作结果，则将其排除。然后进行荟萃分析计算。结果：基于随机效应模型的荟萃分析显示，在颞骨模拟器上进行培训后，乳突切除术的总体操作水平有所提高。在异质性研究人群中（I = 64.3%，P <.006）产生了标准化均数差0.87（95% CI，0.38 - 1.35）。结论：在虚拟现实模拟颞骨手术研究的多样化人群背景下，荟萃分析计算表明虚拟模拟培训可提高学员乳突切除术的操作水平。
