Hello. Our situations sound similar. My tumor was resting on my optic chiasm causing vision issues with both eyes, and extreme headaches. Mine also is invading my right sphenoid sinus cavity and resting near my carotid artery. I had nasal endoscopic surgery in September 2012. I will have a follow up gamma knife next month.
My neurosurgeon was phenomenal. His name is Dr. Zipfel. He is at Barnes-Jewish in St. Louis. My vision has been restored. I have other issues related to my thyroid now, but I can see. I highly recommend him.
