The Karl Storz Company recently introduced a new exoscopic system equipped with new features and improvements compared to older counterparts. The endpoints of this study are to evaluate the new VITOM Eagle system and compare it to the older VITOM 3D for micro-laryngeal surgery, to analyze the new features of the latest Karl Storz's product and determine whether these upgrades provide a significant advantage to surgery of the laryngeal district.
Participants simulated CO Transoral Laser Microsurgery (CO TOLMS) procedures on 3D-printed laryngeal models firstly with both the VITOM 3D and VITOM Eagle. At the end of both sessions 2 questionnaires were administered: the first generic 3-item questionnaire comparing evaluating exoscopic and microscopic technology, the second questionnaire involved 8 items related to device quality.
Overall the new VITOM Eagle resulted superior to the older VITOM 3D, there were statistically significant differences in scores evaluating the image quality (p = 0.002), magnification rate (p = 0.002), and luminance (p = 0.047). In addition, according to questionnaires results, senior Otolaryngologists appeared to be slightly less inclined to a complete transition to exoscopy when compared to young surgeons.
The results of this study demonstrate how the new VITOM Eagle significantly outperforms the older VITOM 3D. The upgrades discussed, have the potential of leading to better surgical outcomes by providing surgeons with better tools to navigate complex anatomical districts. Furthermore, results from this study highlighted how exoscopy is affecting the surgical training of young surgeons.
卡尔·史托斯公司最近推出了一种新的外视镜系统，与旧款相比具有新功能和改进。本研究的目的是评估新型VITOM Eagle系统，并将其与旧款VITOM 3D用于显微喉镜手术进行比较，分析卡尔·史托斯最新产品的新特性，并确定这些升级是否为喉部手术带来显著优势。
参与者首先使用VITOM 3D和VITOM Eagle在3D打印的喉部模型上模拟CO₂ 经口激光显微手术（CO₂ TOLMS）操作。在两个阶段结束时，发放了两份问卷：第一份是通用的3项问卷，用于比较评估外视镜和显微镜技术；第二份问卷涉及与设备质量相关的8个项目。
总体而言，新型VITOM Eagle优于旧款VITOM 3D，在评估图像质量（p = 0.002）、放大率（p = 0.002）和亮度（p = 0.047）的得分上存在统计学显著差异。此外，根据问卷结果，与年轻外科医生相比，资深耳鼻喉科医生似乎不太倾向于完全转向外视镜检查。
本研究结果表明新型VITOM Eagle明显优于旧款VITOM 3D。所讨论的升级有可能通过为外科医生提供更好的工具来应对复杂的解剖区域，从而带来更好的手术效果。此外，本研究结果突出了外视镜检查对年轻外科医生手术培训的影响。
