个体化三维数字模型在内镜颞下锁孔入路岩斜区解剖中的应用
The application of individual three-dimensional digital manikin in endoscopic anatomy of petroclival region via subtemporal keyhole approach
摘要
Abstract
Objective To study the application of individual three-dimensional digital manikin(3D-DM) in endoscopic anatomy of petroclival region via subtemporal keyhole approach, and to investigate its value in clinical application. Methods 10 adult cadaveric heads (20 sides) after perfused were scanned by CT. The images were imported to 3Dview software and reconstructed individual 3D-DM. Day rhombus were oriented and then the related anatomic structure distance were measured. The petroclival region and adjacent structures were proceed endoscopic anatomy in 3D-DM-assistance by subtemporal keyhole approach,the visions and data between 3D-DM and endoscopic anatomy were compared. Results The images of 3D-DM were clear and vivid. The data was not significant different between approach related measurement and endoscopic anatomy. The internal auditory canal could be accurately located by combined anatomic landmarks such as the foramen spinosum, foramen ovale, arcuate eminence, geniculate ganglion, malleus, eustachian tube, greater superficial petrosal nerve and so on. The upper-middle clivus structure could be fully exposed through subtemporal keyhole approach, after removal of petrous apex bone. Conclusions 3D-DM can be used to simulate bone window formation of petrous apex preoperatively,which can improve the accuracy and security of the surgery. The combined anatomic landmarks can improve the accuracy of intraoperative localization of the internal auditory canal. Through the endoscopic subtemporal keyhole approach, the structures of the upper-middle clivus can be fully exposed.关键词
