Figure 5: (a) Exposure and release of MOB. After sharp separation of MOB from the medial compartment of SOF, the MOB (arrowhead) floated obscuring the upper rim of GWS and edge of LWS. The MOB was removed by piecemeal excision to expose the FT. d. The meningo-orbital artery was cut (arrow). (b) Exposure of LWS from lateral until the optic strut ending at the optic nerve and the medial compartment of SOF. (c) The periorbita retracted and LWS drilled from lateral to medial. The dissector is protecting the medial compartment of SOF. (d) A panoramic 30-degree endoscopic trans maxillary view with slight orbital retraction showing drilled LWS and base of ACP. (e) Close endoscopic transmaxillary view showing a 360-degree decompression of SOF after the drilling the edge of LWS, OS, and base of the ACP. MOA: meningo-orbital artery, LWS: lesser wing of sphenoid, GWS: greater wing of sphenoid, ACP: anterior clinoid process, ACPb: base of anterior clinoid process, OS: optic strut, MOB: meningo-orbital band, ON: optic nerve, MCFd: middle cranial fossa dura, cav: cavernous sinus, mSOF: medial compartment of SOF, ION: infraorbital nerve, FT d: frontotemporal dural junction, max: the posterior wall of maxilla
