However, lesions in the parasagittal perirolandic region pose a therapeutic challenge due to high eloquence and the \"gravity-buoyancy conflict.\" Under physiological conditions, cerebrospinal fluid buoyancy reduces the brain's effective weight by approximately 95%. Loss of this support upon opening the dura leads to gravitational sag of the hemisphere. This increased functional weight pulls the bridging veins downward, creating a valve-like effect and a mechanical kink at the rigid dural entry point. A 59-year-old male presented with a 3-cm cystic metastasis in the posterior superior frontal gyrus (SFG). Intraoperatively, gravitational sag of the tumor-expanded gyrus created significant downward traction on the vein of Trolard. This tension induced a potential focal kink at the rigid dural interface, resulting in flow stasis, recognized by distal colorless depletion and dark, pulsatile proximal blood. Consent for the procedure and image publication was obtained, and Queen's University Ethics Board approved this report. Wide splitting of both the superior frontal and precentral sulci allowed for necessary safe access to the tumor and potential decoupling of the tumor-bearing SFG from the hemisphere. To resolve the dural entry kink, a strategic wide arachnoid release was performed along the vein to provide vascular laxity. After early cyst drainage and unloading the pathological weight, the created laxity allowed the vein to return to its physiological location, resolving the stasis.

The variability in tumor burden, challenging anatomy, and associated symptomatology require an individualized and multidisciplinary approach. The relative paucity of cases and variation in surgical anatomy prompt the need for accrual of cases in literature to advance the understanding of surgical techniques to address this rare clinical entity. <b>Clinical Presentation</b> A 19-year-old patient presented with severe and globe-threatening left eye proptosis, negatively affecting quality of life, due to a sporadic intraorbital ONG that had been inexorably growing over the previous 9 years, despite chemotherapy. The patient was taken to the operating room for a single-stage globe-sparing transorbital resection of the intraorbital ONG. The surgical plan consisted of an endoscopic endonasal approach for medial and inferior orbital wall decompression combined with an open lateral orbitotomy, via a lateral canthal incision, for subtotal piecemeal tumor resection to relieve the proptosis, restore alignment of the globe, and yield tissue for molecular analysis. The patient experienced profound improvement in quality of life and opted for radiographic surveillance that has been stable at 5 years. <b>Discussion and Conclusion</b> Surgical approaches to intraorbital tumors have included both transcranial and/or transorbital routes, with the latter more recently encompassing endoscopic endonasal techniques.

To prevent serious complications and achieve optimal outcomes, recreation of airtight and watertight barrier between the anterior cranial fossa and the sinonasal cavity and ensuring mechanical support are essential. The free fascia lata graft currently represents the gold standard for endonasal endoscopic dural reconstruction following tumor resection.
