Objective: Assessment is key in modern surgical education to monitor progress and document sufficient skills. Virtual reality (VR) temporal bone simulators allow automated tracking of basic metrics such as time, volume removed, and collisions. However, adequate performance assessment further includes compound rating of the stepwise bony excavation, and exposure and preservation of soft tissue structures.

Simulator-based assessment of otoscopy skills exists, but evidence on its validity is scarce. In this study, we explored automated assessment and performance metrics of an otoscopy simulator through collection of validity evidence according to Messick's framework.

Purpose: To investigate the impact of 3D-printed temporal bone models with two different material transparencies on trainees' mastoidectomy performance.
Methods: Eleven ORL residents performed two anatomical mastoidectomies with posterior tympanotomy on two 3D-printed models with different transparency and VR simulation training. Participants where divided into two groups based on their experience.
Objective: 3-D printing offers convenient and low-cost mastoidectomy training; nonetheless, training benefits using 3-D-printed temporal bones remain largely unexplored. In this study, we have collected validity evidence for a low-cost, 3-D-printed temporal bone for mastoidectomy training and established a credible pass/fail score for performance on the model.
Study Design: A prospective educational study gathering validity evidence using Messick's validity framework.
