This is my one year anniversary of middle fossa removal of a tumor your size and I am just a little younger. I am happy to be on the other side of surgery and am rid of the tumor. I am also very joyful with life today but it was a very difficult recovery. I wasn't quite prepared for how bad it could be. Prior to the surgery I had perfect hearing, feeling of cotton/fullness in ear, moderate fatigue, and a "floaty" sense of balance. My demeanor was very similar to your post. Removing the tumor sooner than later was to give me the best chance of hearing preservation, non disruption of facial nerve and chance for better balance recovery. After surgery I had complete facial paralysis, permanent and complete single sided deafness, complete removal of balance nerve, csf leak, inability of have eye exposed to air despite the ointments and drops for months, and significant persistent tinnitus. That being said, it was a long road to regain my life back. Despite the complications and difficult recovery I still think I am better off having had the surgery and being rid of the tumor. I don't think though based on everything I went through with all possible complications that you should rush into it. Not a big chance what happened in my case will happen in yours, and I will specifically pray that it does not, but there is a real possibility of significant life disruption. Pick the time it is best for you to potentially dedicate a year to getting better...and be relieved when you are healed much, much sooner complication free.
