I did have surgery this year in August. They went through my nose and then the sinuses to get to it. It was an 8 hour surgery. Recovery was a bit slow compared to others I’ve had. I was starting to rehab, ride the bike and lift weights again at two months. I had double vision for about a month, but mine was against my optic nerve, and it seems his might be in a different position. I wish the best for you both and hope you can have a nice holiday season. Stay positive!
