The aim of this study was to evaluate the Navibase navigation system for ear, nose, and throat (ENT) surgery. A new methodology for evaluating surgical and human factors is developed.
The evaluation is based on 102 ENT surgical applications, including 89 cases of functional endoscopic sinus surgery (FESS). The evaluation of surgical and human factors was performed by seven ENT surgeons. To evaluate surgical performance, level of quality (LOQ) in the 89 cases of FESS was determined, comparing the surgeon's own impressions with those of the navigation system on a scale from 0 to 100 and further comparing them with clinical results. Intraoperative changes in surgical strategy were documented. The human factors of total confidence (trust), situation awareness, skill set requirement and workload shift were recorded as level of reliance (LOR).
The maximum deviation amounted to 1.93 mm. Averaging the quality of information resulted in an LOQ of 63.59. Every second application of the navigation system (47.9%) led to a change in surgical strategy. Total confidence showed a positive evaluation of 3.35 points in LOR.
Application-relevant information relevant to the application beyond only technical details permits comparison with other assisting systems.
本研究旨在评估用于耳鼻喉（ENT）手术的Navibase导航系统。开发了一种评估手术和人为因素的新方法。
评估基于102例耳鼻喉科手术应用，包括89例功能性鼻内镜鼻窦手术（FESS）。由7名耳鼻喉科外科医生对手术和人为因素进行评估。为评估手术效果，确定了89例FESS病例的质量水平（LOQ），将外科医生自己的印象与导航系统的印象按0至100分进行比较，并进一步与临床结果进行比较。记录手术策略的术中变化。将总体信心（信任）、态势感知、技能要求和工作量转移等人为因素记录为依赖程度（LOR）。
最大偏差为1.93毫米。信息质量平均得分为63.59分（LOQ）。导航系统每两次应用中就有一次（47.9%）导致手术策略改变。总体信心在LOR中得到了3.35分的积极评价。
与应用相关的信息，不仅仅是技术细节，允许与其他辅助系统进行比较。
