Tumors of the Orbit: Case Report and Review of Surgical Corridors and Current Options

Satish Kannan et al. Asian J Neurosurg. 2019 Jul-Sep.

Abstract

Tumors that involve the orbit can be classified into two major groups: primary tumors of the orbit and tumors that extend into the orbit from other sites. The most frequent primary orbital lesions in adults include cavernous hemangiomas, lymphoid tumors, and meningiomas. The most common tumors that extend into the orbit are meningiomas, followed by sinonasal carcinomas. In this article, we report a case of intraconal orbital lesion operated at our center and a review of the surgical approaches to the orbit.

Keywords: Cavernous angioma; endoscopic approach to orbit; intraconal/extraconal orbital tumors; orbital anatomy; orbital tumors; surgical approach to the orbit.
