Pterional/Lateral Approach to Orbital Tumors

Abstract

The purpose of this article is to detail our experience with an approach to primary pathologic conditions involving the orbit. In 27 patients these included tumors of the lacrimal gland, lymphangiomas, neurinomas, meningiomas, and various cysts of the orbit. Access to these lesions was gained by a lateral pterional approach with osteoclastic or osteoplastic removal of the lateral bony wall/roof of the orbit, and by entering adnexal contents following elevation of the lateral rectus muscle. This approach allowed for complete tumor removal in all patients. The specifics of this approach will be discussed and associated orbital complications will be detailed.
