The quadrangular space permits an anterior entry into Meckel's cave while obviating the need for cerebral or cranial nerve retraction. This avenue is intimately associated with the cavernous sinus; thus, from this ventral perspective, it is feasible to visualize the anteromedial, anterolateral, and Parkinson triangles.
Twenty middle cranial fossae were dissected endonasally under direct endoscopic visualization. Measurements of the surface area of the quadrangular space and the ventrally accessible cavernous sinus triangles were performed using 3 coordinates under image-guided navigation.
The surface area of the quadrangular space was 16.36 mm(2) (±2.89 mm(2) ). The anterolateral triangle was the largest (47.27 ± 5.37 mm(2) ), whereas Parkinson's was the smallest (22.46 ± 5.54 mm(2) ); the anteromedial triangle presented an average surface area 36.07 mm(2) (±4.15 mm(2) ).
The trajectory of the internal carotid artery (ICA) significantly impacts the quadrangular space area and may be a potential parameter for defining the feasibility of this corridor. © 2016 Wiley Periodicals, Inc. Head Neck 38: E1680-E1687, 2016.
四边形间隙允许从前路进入梅克尔腔，同时无需牵拉脑组织或脑神经。该路径与海绵窦密切相关；因此，从这个腹侧视角，可以看到前内侧、前外侧和帕金森三角。
在直接内镜观察下经鼻解剖20个中颅窝。在图像引导导航下使用三维坐标测量四边形间隙和腹侧可及的海绵窦三角的表面积。
四边形间隙的表面积为16.36平方毫米（±2.89平方毫米）。前外侧三角最大（47.27±5.37平方毫米），而帕金森三角最小（22.46±5.54平方毫米）；前内侧三角的平均表面积为36.07平方毫米（±4.15平方毫米）。
颈内动脉（ICA）的走行显著影响四边形间隙面积，可能是确定该通道可行性的一个潜在参数。©2016威利期刊公司。《头颈》38: E1680 - E1687, 2016。
