Abstrakt:	Background and Importance: Various invasive oculoplastic procedures are commonly utilized to control the rectus muscles and widen the surgical corridor through the endoscopic endonasal removal of large orbital apex cavernous hemangiomas (OACHs). They require additional transconjunctival incision, rectus muscle insertional retraction, or muscle deinsertion at the globe that might not be safe and lead to prolonged postoperative extraocular muscle dysfunction. In this article, the authors described a modified 3-handed extracapsular technique for the resection of a large OACH without an additional procedure for rectus muscle control. The aim is to achieve a safe gross total tumor removal while minimizing the procedure-related complications. An intraoperative video is included, along with a stepwise cadaveric dissection relevant to the approach. Clinical Presentation: A 71-year-old female presented with progressive left-sided blurred vision, binocular diplopia, and mild proptosis. Contrast-enhanced brain MRI revealed a large heterogeneous enhanced inferomedial intraconal mass in the left orbital apex, mostly consistent with cavernous hemangioma. Gross total tumor removal was achieved through a modified 3-handed endoscopic endonasal extracapsular approach. The diplopia was resolved, and significant visual improvement was achieved. Computed tomography scan demonstrated complete tumor removal, and histological examination confirmed the diagnosis. Conclusion: Endoscopic endonasal resection of large OACH can be feasibly performed by using a modified 3-handed extracapsular technique through the generous use of Q-tip swab applicators within the natural separation plane around the tumor capsule and a sequential traction-countertraction method. Subsequently, a gross total removal and optimal postoperative functional outcome are attainable through minimal rectus muscle fiber violation and intraconal fat manipulation.
