OBJECTIVES/HYPOTHESIS: To present and evaluate the magnetic-based phonomicrosurgery instrument tracking system, a novel and objective method of acquiring instrument position data during simulated phonomicrosurgery. The position data can be used to compute quantitative motion metrics. This system was used to objectively evaluate the motion performance of novice and expert surgeons during phonomicrosurgical simulations and determine the differences between these groups.
Prospective cohort study.
A magnetic-based phonomicrosurgery instrument tracking system was developed, including a workbench, independent task, motion metrics, and computer program. Based on this system, three experts' and six novices' motion data were collected and analyzed.
Experts demonstrated significantly better motion smoothness along the y-axis for the dominant hand. For the nondominant hand, experts demonstrated better motion smoothness along all three axes, shorter path length, and better depth perception (P < .05). Experts also demonstrated higher quality of operation (P < .001). No significant difference in time was noted (P = .671).
Parameters derived from magnetic-based motion tracking were able to differentiate between expert and novice surgeons. These parameters have the potential to be used in phonomicrosurgical training as feedback to enhance the training process.
目的/假设：介绍并评估基于磁的嗓音显微手术器械跟踪系统，这是一种在模拟嗓音显微手术中获取器械位置数据的新颖且客观的方法。这些位置数据可用于计算定量运动指标。该系统用于客观评估新手和专家在嗓音显微手术模拟中的运动表现，并确定两组之间的差异。
前瞻性队列研究。
开发了一种基于磁的嗓音显微手术器械跟踪系统，包括工作台、独立任务、运动指标和计算机程序。基于该系统，收集并分析了 3 名专家和 6 名新手的运动数据。
专家在主导手的 y 轴上表现出明显更平滑的运动。对于非主导手，专家在所有三个轴上表现出更平滑的运动、更短的路径长度和更好的深度感知（P<.05）。专家还表现出更高的手术质量（P<.001）。操作时间无显著差异（P=.671）。
基于磁运动跟踪得出的参数能够区分专家和新手外科医生。这些参数有可能作为反馈用于嗓音显微手术培训，以增强培训过程。
