The aim of this study is to evaluate the feasibility of the 3D exoscope in a microvascular anastomosis training setting and compare it with the gold-standard technique using the operating microscope (OM).
Participants were recruited among otorhinolaryngology head and neck surgery (OHNS) residents of two tertiary care hospitals. Trainees were asked to complete 4 microvascular end-to-end anastomoses on chicken thighs with the OM and VITOM 3D exoscope. The performances were scored by experienced microvascular surgeons; an objective evaluation of the anastomosis and a subjective assessment of the workload were conducted.
8 OHNS residents were recruited. Considering the amount of time needed to complete (TTC) the anastomosis, an improvement was shown by all the participants throughout the training program. The objective evaluation of the anastomosis did not show a significant difference. No significant differences were found by analyzing the subjective workload with the different tools.
This article represents the first attempt to compare the use of the OM and the 3D exoscope during training for microsurgery. The results of our study demonstrate the noninferiority of microsurgical training obtained using the 3D exoscope compared to that offered by the OM.
本研究旨在评估 3D 手术显微镜在微血管吻合术培训环境中的可行性，并将其与使用手术显微镜（OM）的金标准技术进行比较。
参与者招募自两家三级护理医院的耳鼻喉头颈外科（OHNS）住院医师。要求受训者使用 OM 和 VITOM 3D 手术显微镜在鸡大腿上完成 4 个微血管端端吻合术。由经验丰富的显微外科医生对手术表现进行评分；对吻合进行客观评估，并对工作量进行主观评估。
共招募了 8 名 OHNS 住院医师。考虑到完成吻合所需的时间（TTC），所有参与者在整个培训计划中都有所提高。吻合的客观评估没有显示出显著差异。使用不同工具分析主观工作量时，未发现显著差异。
本文首次尝试比较 OM 和 3D 手术显微镜在显微外科培训中的使用。我们的研究结果表明，使用 3D 手术显微镜进行的显微外科培训与 OM 提供的培训相比具有非劣效性。
