Hi barber and welcome to this forum .....
So sorry you are dealing with the thought of a second surgery. I can identify .....
My first AN surgery was via retrosigmoid approach. However, I was told the tumor was entirely removed so I was very dismayed when three years later it was deemed the "residual scar tissue" showing on the MRIs actually grew into a regrown tumor.
It was removed a second time via translabyrinthine approach. I had no facial involvement, other than mild facial weakness for a couple of weeks ..... no headaches.
When one is in a regrowth situation, you want the most experienced surgeons you can find. Therefore, I chose wisely for that second surgery and had a positive outcome. Because I knew the translab would cause total deafness in my AN ear, I had my Oticon Medical Ponto Pro abutment placed at the same time. I love my bone-anchored hearing device.
Many thoughts and prayers for a successful second surgery.
