目的研究个体化三维数字模型(three-dimension digital manikin,3D-DM)在内镜经鼻颞骨岩部解剖中的应用,探讨其临床应用价值。方法 10例(20侧)成人头部标本灌注后经CT扫描,将图像导入3Dview软件,重建出个体化3D-DM,运用“逆向骨窗形成”技术设计并模拟颞骨岩部骨窗形成。然后在3D-DM辅助下对颞骨岩部进行内镜解剖,对头部标本解剖与个体化3D-DM视野及相关测量进行比较。结果通过逆向骨窗形成技术可术前模拟颞骨岩部磨除,头部标本解剖与个体化3D-DM下视野高度一致,相关测量间比较无统计学差异。结论个体化3D-DM为内镜下经鼻入路暴露颞骨岩部提供详尽解剖数据,可以术前模拟颞骨岩部磨除,提高术中颞骨岩部磨除的准确性和安全性,对该手术入路的临床应用具重要指导意义。
Objective To study the application of three-dimension digital manikin (3D-DM) in the anatomy of the endoscopic nasolabial petrosal bone and to explore its clinical value. Methods Ten cases (20 sides) of adult head were perfused with CT scans, and the images were imported into 3Dview software to reconstruct the individualized 3D-DM. The bone window formation was simulated and modeled by the “Reverse Oscillator Forming” technique. Then, with the aid of 3D-DM, the temporal petrosal bone was subjected to endoscopic dissection. The head anatomy and individualized 3D-DM visual field and related measurements were compared. Results The reverse osseous window formation technique was used to simulate the ablation of the petrous bone and petrous bone. The anatomy of the head was consistent with the visual field under the individualized 3D-DM. There was no significant difference between the related measurements. Conclusion Individualized 3D-DM provides detailed anatomical data for the exposure of the temporal bone rock by endoscopic transnasal approach. It can simulate the removal of the petrous bone rock before surgery and improve the accuracy and safety of ablation of the petrous bone in the operation. The clinical application of an important guiding significance.
