Endoscopic Transnasal Septotomy for Contralateral Orbital Apex Venous Angioma Resection and Decompression

ABSTRACT

Tumors of the orbital apex region are traditionally difficult to approach surgically due to key anatomic structures found in this highly crowded region. We present a case of progressively enlarging orbital apex venous angioma treated with a novel endoscopic transnasal septotomy technique. We highlight the key steps to this approach, as well as specific landmarks necessary to achieve a safe and successful outcome.

• Transnasal septotomy
• septal window
• trans-septal
• orbital apex lesion resection
• medial orbital approach
