未经证实:眼眶底骨折常见于中面骨折。他们的管理包括恢复眼眶体积和解剖结构。然而,这些手术可能与植入物的错位和体积恢复不足有关.如今医疗快速成型,虚拟规划(VP)和导航系统大大提高了此类程序的精度。然而,术中导航的应用可能与二维成像相关的术中错误有关.混合现实(MR)的应用可以解决这个问题。本研究旨在证明MR在眼眶重建中的应用。
UNASSIGNED:目前的研究包括MR在眼眶重建中的实验和临床实施。在实验部分,增加了10名居民和5名经验丰富的颌面外科医生。所有数据和定制软件都有很好的记录,然后用于单个临床病例的眶底重建。
UNASSIGNED:在实验中对钢板定位的视觉评估显示8例钢板定位正确。虚拟和真实测量的比较显示出0.65-1.15的稳定偏差(平均0.9mm)。由于MR技术的临床实施,手术重建后,患者显示眼活动度改善和复视减少。术后计算机断层扫描显示正确的板定位。
UNASSIGNED:实施基于VP的MR可以显着改善术前计划的结果,术中导航,和手术。然而,与导航原理相关的现有技术限制可能会产生错误和错误。因此,与6个自由度问题解决方案相关的进一步调查在消除列出的问题时被认为是合理的。
UNASSIGNED: Orbital floor fractures are common within midface fractures. Their management includes restoration of orbital volume and anatomy. However, these procedures could be associated with the mispositioning of implants and inadequate volume restoration. Nowadays medical rapid prototyping, virtual planning (VP), and navigation systems significantly increase the precision of such procedures. Nevertheless, the application of intraoperative navigation could be associated with intraoperative mistakes related to two-dimensional imaging. The application of mixed reality (MR) could solve this problem. The current
study aims to demonstrate the application of MR in orbital reconstruction.
UNASSIGNED: The current
study included experimental and clinical implementation of MR in orbital reconstruction. Within the experimental part, 10 residents and 5 experienced maxillofacial surgeons were added. All data and customised software were well documented and then used in a single clinical case of orbital floor reconstruction.
UNASSIGNED: Visual assessment of plate positioning within the experiment revealed proper plate positioning in 8 cases. A comparison of virtual and real measurements showed a stable deviation of 0.65-1.15 (mean 0.9 mm). As a result of the clinical implementation of MR technology, after surgical reconstruction, the patient showed improvement in ocular mobility and reduction of diplopia. A postoperative computed tomography scan showed proper plate positioning.
UNASSIGNED: Implementation of MR based on VP could significantly improve the results of preoperative planning, intraoperative navigation, and surgery. However, existing technical limitations that relate to navigation principles could produce mistakes and errors. Therefore, further investigations related to the 6 degrees of freedom problem solution are considered reasonable in the elimination of listed issues.
