The supraorbital eyebrow approach (SEa) has been commonly used as a straightforward route to reach lesions located in the anterior cranial fossa. The reduced surgical exposure provided by this approach limits its applicability. A modification of the SEa, the extended supraorbital eyebrow approach (X-SEa), allows use of the transylvian corridor to approach parasellar lesions, while maintaining most of the aesthetic advantages of the SEa. To quantify the surgical exposure and maneuverability provided by the X-SEa using a cadaveric study. Eleven heads were used to obtain all stereotactic measurements. Surgical exposure and maneuverability were measured by means of the area of exposure and the angles of attack along key representative points in the anterior circulation. The horizontal angle of attack at the middle cerebral artery provided by the X-SEa was larger than that provided by the SEa (32.6 vs 18.4°, p = 0.009). The X-SEa afforded broader vertical angles of attack at all targets in the anterior circulation (p < 0.05). The total area of exposure provided by the X-SEa was significantly larger than that provided by the SEa (1272 vs 978 ± 156 mm2, p = 0.003). The area of exposure in the ipsilateral trigon and in the midline quadrangle was also significantly larger for the X-SEa (paramedian 195 vs 121 mm2, p = 0.01; midline 1310 vs 778 mm2, p = 0.002). The X-SEa increases the exposure and surgical maneuverability along the anterior and middle cranial fossa when compared to the standard SEa.

相同的视角，最小的颅骨切开术扩大，极度暴露增加：眶上眉延长法。

眶上眉法（SEa）通常被用作到达位于颅前窝的病变的直接途径。这种方法减少了手术暴露，限制了其适用性。SEa的一种改进，即眶上眉法（X-SEa），可以使用transylvian走廊接近肩旁病变，同时保留SEa的大部分美学优势。为了使用尸体研究量化X-SEa提供的手术暴露量和可操作性。11个头用于获得所有立体定向测量值。通过暴露面积和沿前循环关键代表点的攻角来测量手术暴露和可操作性。X-SEa在大脑中动脉处的水平攻角大于SEa所提供的水平攻角（32.6对18.4°，p = 0.009）。X-SEa在前循环中的所有目标处均提供了更宽的垂直攻角（p <0.05）。X-SEa提供的总暴露面积明显大于SEa提供的总暴露面积（1272对978±156 mm2，p = 0.003）。X-SEa在同侧三角形和中线四边形中的暴露区域也显着更大（中间值195对121 mm2，p = 0.01；中线1310对778 mm2，p = 0.002）。与标准SEa相比，X-SEa会增加颅前窝和中颅窝的暴露量和手术可操作性。X-SEa在前循环中的所有目标处均提供了更宽的垂直攻角（p <0.05）。X-SEa提供的总暴露面积明显大于SEa提供的总暴露面积（1272对978±156 mm2，p = 0.003）。X-SEa在同侧三角形和中线四边形中的暴露区域也显着更大（中间值195对121 mm2，p = 0.01；中线1310对778 mm2，p = 0.002）。与标准SEa相比，X-SEa会增加颅前窝和中颅窝的暴露量和手术可操作性。X-SEa在前循环中的所有目标处均提供了更宽的垂直攻角（p <0.05）。X-SEa提供的总暴露面积明显大于SEa提供的总暴露面积（1272对978±156 mm2，p = 0.003）。X-SEa在同侧三角形和中线四边形中的暴露区域也显着更大（中间值195对121 mm2，p = 0.01；中线1310对778 mm2，p = 0.002）。与标准SEa相比，X-SEa会增加颅前窝和中颅窝的暴露量和手术可操作性。X-SEa在同侧三角形和中线四边形中的暴露区域也显着更大（中间值195对121 mm2，p = 0.01；中线1310对778 mm2，p = 0.002）。与标准SEa相比，X-SEa会增加颅前窝和中颅窝的暴露量和手术可操作性。X-SEa在同侧三角形和中线四边形中的暴露区域也显着更大（中间值195对121 mm2，p = 0.01；中线1310对778 mm2，p = 0.002）。与标准SEa相比，X-SEa会增加颅前窝和中颅窝的暴露量和手术可操作性。
