虚拟现实术前计划在复杂颅底肿瘤中的应用——附6例典型病例分析

Virtual Reality Preoperative Planning in Complex Skull Base Tumor Surgery: Analysis of 6 Cases

背景与目的:颅底肿瘤手术涉及复杂的解剖结构,详细了解患者个体化的解剖特点对制定术前计划很重要。本文探讨Destroscope虚拟现实系统在复杂颅底肿瘤术前计划中的作用。方法:列举6例复杂颅底肿瘤病例,将其CTA、MRI、CT等影像资料在Destroscope虚拟现实系统中三维重建、融合,个体化设计手术入路。结果:6例复杂颅底肿瘤患者中,全切4例,次全切1例,部分切除1例。最少随访5个月,全切病例未见肿瘤复发。结论:Destroscope虚拟现实系统能够显示的肿瘤大小、部位、侵及范围等空间关系,有助于个体化设计最佳手术入路,提高手术疗效。

BACKGROUND ＆ OBJECTIVE： The skull base tumor resection deals with complex anatomy structure, and it is very important to analyse the anatomic characteristics of the patients in detail for surgery plan. To explore the value of Destroscope virtual reality system in preoperative planning for complex skull base tumor resection. METHODS： DICOM data of CTA, MRI and CT were transferred to and reconstructed in the Destroscope virtual reality system. Preoperative planning was performed. Individualized surgical approach was optimized in the virtual reality environment. RESULT： Among 6 patients with complex skull base tumors, total removal was achieved in 4 cases, subtotal removal in 1 case and partial removal in 1 case, respectively. No tumor recurrence occurred in the 4 cases with total removal during a 5-month follow-up period. CONCLUSION： Destroscope virtual reality system can reveal clearly the size, location and involvement extent of the tumors. The system is helpful to optimize the surgical approach individually and improve the efficacy of the surgical procedures.
