Cavernous sinus meningioma

Hello, I have recently been diagnosed with a right cavernous sinus meningioma that has wrapped around the carotid artery and is pressing on the optic nerve and 2 other cranial nerves. Even though I live in a large city, I feel very limited by the physicians whom I have seen so far. They first said, I will see you after surgery. Then inoperable due to the area and surrounding structures and I am finally getting a second opinion where I have found out that radiation to or around the optic nerve is very dangerous. Has anyone had surgery in this area successfully or did you forgo surgery for radiation and how did that effect your vision and optic nerve ( I have double vision and severe headaches , as well as, a few other symptoms like ringing in the ears, face pain etc. I would appreciate any comments and experiences, thank you
