摘要

目的经鼻内镜入路（endoscopic endonasal approach，EEA）是显露腹侧颅底并处理相关病变非常适合的入路，探讨多模态电磁导航在辅助新鲜尸头EEA解剖中的作用。方法探索新鲜尸头标本的多模态重建；验证电磁导航在EEA中深部结构测量的精确性；利用电磁导航定位鼻腔及鼻窦内特征性的解剖标记。结果新鲜尸头的计算机断层扫描（computed tomography，CT）及磁共振成像（magnetic resonance imaging，MRI）的T1序列可用于多模态重建，其他序列失败；电磁导航测量结果与毫米软尺测量结果无统计学差异，证实电磁导航适合用于新鲜尸头EEA深部测量。结论 CT及MRI的T1序列可用于对新鲜尸头EEA的深部多模态电磁导航测量；导航定位鼻腔及鼻窦内特征性的解剖标记，为后续颅腔内解剖测量提供基础。

Abstract

Objective To explore the role of multimodal electromagnetic navigation in assisting endoscopic endonasal approach (EEA) dissection of fresh cadavers. Methods Multi-modal reconstruction of fresh cadaveric head specimen was explored, the accuracy of electromagnetic navigation in the measurement of deep structure in EEA was verified. Electromagnetic navigation was used to locate the characteristic fixed bony markers in the nasal cavity and sinuses. Results The computed tomography (CT) and magnetic resonance imaging (MRI) T1 sequences of fresh cadavers could be used for multimodal reconstruction, but other sequences failed. There was no statistical difference between the measurement results of electromagnetic navigation and millimeter soft ruler, which confirmed that electromagnetic navigation was suitable for EEA deep measurement of fresh cadavers. Conclusions CT and the T1 sequence of MRI can be used for EEA measurement of fresh cadaveric by multi-modal electromagnetic navigation. Positioning of characteristic anatomical markers in the nasal cavity and sinuses by navigation provides basis for subsequent intracranial anatomical measurement
