I am 25 years old and I had my 4.9 cm AN partially removed back in 2014. Following my first surgery, I had facial paralysis for a few weeks that I was able to correct with facial exercises. Now it is starting to grow again and I’m concerned about undergoing CyberKnife radiation. I’ll be having 5 sessions (each 1 hour) of radiation over a week and a half this summer and I’m concerned about facial paralysis and regrowth again after this procedure. What is the success rate of CyberKnife procedures? Is facial paralysis something I should be concerned about again?
