To provide a new approach for the treatment of tumor in Meckel's cave, by dissecting adjacent structures of the nasal cavity-maxillary sinus-pterygopalatine fossa-Meckel's cave approach.
Fifteen adult cadaver heads (30 sides) were dissected and the correlated anatomic landmarks were observed, measured and analyzed in an operative route.
The approach was divided into 3 steps: entering the maxillary sinus, the later pterygopalatine fossa and the final Meckel's cave. Safe access to Meckel's cave could be achieved by tracing the vidian neurovascular bundles and dissecting the quadrangular space (QS). The distances from the nasal columella to the apertura maxillaries, the sphenopalatine foramen, and the anterior foramen of the pterygoid canal were (44.08+/-2.61) mm, (64.83+/-2.42) mm, and (70.43+/-2.94) mm, respectively. The angles between the horizontal plate of the palatine bone and the link from nasal columella to apertura maxillaries, between the horizontal plate of the palatine bone and the link from nasal columella to sphenopalatine foramen were (38.10+/-2.46) degrees and (26.15+/-2.26) degrees , respectively.
The endoscopic approach of transnasal maxillary sinus-pterygopalatine fossa-Meckel's cave (ENMPA) is a safe and direct way to access Meckel's cave, and could be employed for the treatment of tumor in Meckel's cave.
通过经鼻腔-上颌窦-翼腭窝- Meckel 腔入路解剖毗邻结构，为 Meckel 腔肿瘤的治疗提供一种新的方法。
解剖 15 具成人尸头（30 侧），观察、测量和分析手术入路相关解剖标志。
该入路分为 3 步：进入上颌窦、后翼腭窝和最终的 Meckel 腔。通过追踪血管神经束和解剖四边形间隙（QS），可以安全地到达 Meckel 腔。从鼻中隔到上颌窦开口、蝶腭孔和翼突管前孔的距离分别为（44.08+/-2.61）mm、（64.83+/-2.42）mm 和（70.43+/-2.94）mm。腭骨水平板与鼻中隔到上颌窦开口连线、腭骨水平板与鼻中隔到蝶腭孔连线之间的夹角分别为（38.10+/-2.46）度和（26.15+/-2.26）度。
经鼻内镜上颌窦-翼腭窝- Meckel 腔入路（ENMPA）是一种安全、直接到达 Meckel 腔的方法，可用于治疗 Meckel 腔肿瘤。
