Big hugs, Jakesmom. I am so sorry your son and your family is going through this - it sounds like he is quite a fighter and he is lucky to have such a great family to support him. I said over and over again during my diagnosis that I was so glad this was happening to me rather than my kids.
I just had my surgery (translab - and I see that is probably not an option for him) at the House clinic (Drs. Slattery and Schwartz) and it was an excellent experience. I would recommend them in a heartbeat. Has your son lost any of his hearing on the AN side, yet? From my understanding, surgery can not restore hearing but it can stop it's decline, depending on the location of the tumor. I would send his MRIs to the House clinic doctors, along with any hearing tests and they will call you (free consultation). I think there may be a few other free consults, too. The House will take very good care of you - they will not take advantage of you (Dr. Schwartz straight up told me I would probably have the same outcome from surgery or radiation, it's just which ever I was more comfortable with). I have never met more compassionate doctors in my life.
Also, if it's any consolation, my pain was never above a 7 on the 10 scale and that was just in the first few days - as a mom, that's something I'd be concerned about for my child, too.
