Abstract

Introduction: Fibrous dysplasia of the craniofacial bones, or craniofacial dysplasia (CFD), involves the replacement of normal bone with fibrous osseous tissue, resulting in asymmetry and distortion of the overlying soft tissue and irregular bone deposition. Treatment primarily involves surgical resection, and achieving symmetry by matching the contralateral unaffected side is crucial. However, surgical correction is challenging due to the lack of visualization of the normal contralateral structures and the need to precisely control resection depth. Although the application of an augmented reality navigation (ARN) system for CFD surgery has been documented, to our knowledge its specific use in identifying key neurovascular structures has not been reported.

Methods: We present the application of an ARN system for the surgical management of an 18-year-old woman with CFD. The virtual plan was designed to visualize the extent of tumor, identify normal and abnormal vasculature, and guide the reconstruction of a normal anatomical contour.

Results: ARN was successfully integrated into the surgical workflow and optimized operative planning, identification of tumor margins, avoidance of neurovascular structures, reconstruction, and symmetric recontouring. The ability to visualize structures in real time proved to be especially beneficial for making intraoperative adjustments.

Conclusion: ARN has significant applications for CFD surgery by providing real-time, three-dimensional simulation, and precise overlay of patient-specific anatomy and pathology, facilitating safe resection, and providing a useful reconstruction guide. To our knowledge, this report presents the first detailed description of its utility in visualizing critical neurovascular structures, offering significant potential to enhance surgical safety and patient outcomes.

增强现实导航在颅面纤维发育不良手术中的应用。
颅面骨纤维性发育不良,或称颅面发育不良(CFD),涉及到正常骨被纤维性骨组织取代,导致上覆软组织的不对称和扭曲以及不规则的骨沉积。治疗主要包括手术切除,通过匹配对侧未受影响的一侧来达到对称是至关重要的。然而,由于缺乏对侧正常结构的可视化和需要精确控制切除深度,手术矫正是具有挑战性的。尽管增强现实导航(ARN)系统在CFD手术中的应用已有文献记载,但据我们所知,其在识别关键神经血管结构方面的具体应用尚未见报道。方法:我们介绍了ARN系统在一例18岁女性CFD手术治疗中的应用。虚拟平面的设计是为了可视化肿瘤的范围,识别正常和异常的血管,并指导正常解剖轮廓的重建。结果:ARN成功融入手术流程,优化手术计划,识别肿瘤边缘,避免神经血管结构,重建和对称重轮廓。事实证明,实时可视化结构的能力对术中调整尤其有益。结论:ARN在CFD手术中具有重要的应用价值,可实时、三维模拟、精确叠加患者特异性解剖病理,便于安全切除,并提供有用的重建指导。据我们所知,本报告首次详细描述了其在可视化关键神经血管结构方面的应用,为提高手术安全性和患者预后提供了巨大的潜力。
