Virtual temporal bone dissection system: OSU virtual temporal bone system

Abstract

Objectives/Hypothesis The objective of this project was to develop a virtual temporal bone dissection system that would provide an enhanced educational experience for the training of otologic surgeons. Study Design A randomized, controlled, multi-institutional single blinded validation study. Methods The project encompassed 4 areas of emphasis: structural data acquisition, integration of the system, dissemination of the system, and validation. Results Structural acquisition was performed on multiple imaging platforms. Integration achieved a cost effective system. Dissemination was achieved on different levels including casual interest, downloading of software, and full involvement in development and validation studies. A validation study was performed at 8 different training institutions across the country using a two arm, randomized trial where study subjects were randomized to a two-week practice session using either the virtual temporal bone or standard cadaveric temporal bones. Eighty subjects were enrolled and randomized to one of the two treatment arms, 65 completed the study. There was no difference between the two groups using a blinded rating tool to assess performance after training. Conclusions 1. A virtual temporal bone dissection system has been developed and compared to cadaveric temporal bones for practice using a multi-center trial. 2. There is no statistical difference seen between practice on the current simulator when compared to practice on human cadaveric temporal bones. 3. Further refinements in structural acquisition and interface design have been identified which can be implemented prior to full incorporation into training programs and use for objective skills assessment.

Novel Otolaryngology Simulation for the Management of Emergent Oropharyngeal Hemorrhage

“…Their confidence in multiple skill sets was significantly improved after the boot camp [7]." Other studies have also shown similar results in medicine and the field of otolaryngology [17,18]. All of these studies have consistently shown that through simulation and boot camp training, residents began developing the appropriate knowledge, skill set and self-confidence [2,7] needed to succeed during residency and, more importantly, that these skills transferred to real clinical situations/procedures with real patients.…”

“…And the virtual reality temporal bone dissection training is more effective than the traditional text book based training and as effective as cadaveric temporal bones [14].…”

“…Perhaps the most significant advantage is the ability to objectively monitor and assess trainee actions, providing a basis for formative and summative metrics [13][14][15][16][17][18]. Further, there may be utility in competency based residency training.…”

“…The validity of haptic trainers has been studied, particularly with reference to surgical performance and construct validity [13,[15][16][17]. Direct comparison to performance in standard cadaveric dissection [12,13] have previously shown mixed results.…”
