Endoscopic transpalpebral approach for resection of an intraorbital intraconal cavernous angioma

We present the case of a 47-year-old man with left exophthalmus. MRI showed a left intraorbital intraconal cavernous malformation, located in the superoesternal quadrant and medially displacing the optic nerve. An endoscopic transpalpebral approach was performed and total removal was achieved after dissection of the lesion from the optic nerve and other orbital structures. Pathology confirmed the diagnosis of cavernous malformation. The patient was discharged neurologically intact on the second postoperative day free of complications. Follow-up MRI demonstrated radical resection of the cavernoma and resolution of the exophthalmus with an excellent esthetic result. The video can be found here: https://youtu.be/o1a1tneZ6qk.
