Modified Function-Preserving Endoscopic Endonasal Extracapsular Resection of a Large Orbital Apex Cavernous Hemangioma.

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.
