|Official Title:||Virtual Temporal Bone Surgery: Defining and Translating Metrics|
- Performance on a set of validated metrics for temporal bone surgery. [ Time Frame: one year ]A collection of metrics designed to measure technical performance during a mastoidectomy will be validated by expert survey. These metrics will be translated to an automated system within the surgical simulation system. Resident subjects will be asked to perform the surgical procedure (mastoidectomy) within the simulation. Experts will then rate the playback of the performances using the validated metrics. These results will be compared to the automated scoring system. A conclusion will be drawn about the accuracy of the automated process compared to the expert rated process.
|Study Start Date:||July 2013|
|Study Completion Date:||July 1, 2016|
|Primary Completion Date:||July 1, 2016 (Final data collection date for primary outcome measure)|
All resident study subjects will drill virtual temporal bones within the computer based system. The performance data will be used to validate the rating metrics and computer scoring process.
Other: Simulator training with expert scoring
Residents will be trained using surgical simulation
The aims of this research include: 1) definition of standardized metrics for otological surgical techniques, 2) the translation of those standards into objective criteria for use in a computer synthesized surgical environment, and 3) the correlation between expert evaluation and computer automated assessment of resident proficiency.
The interactions will be computer-based and include:
Experts will learn to use the system so that they can evaluate the quality of translation of metrics to the simulation environment.
Evaluations will be in the form of anonymous web-based surveys. Experts serve as a focus group.
Residents will use the simulation environment to perform surgical procedures on virtual specimens. Residents will then evaluate the quality of the simulation environment via anonymous web-based surveys.
Experts will use the simulation environment to evaluate and rate the residents performance.
The computer environment will be used to automatically assess and rate the residents performance.
Expert and computer assessment will be compared.
