Yeah, 5mm is definitely smaller than 50mm (5cm).. That's definitely on the small side, however given that you're already having facial tingles and numbness, that means the facial nerve is being affected in some way with the tumor there. Usually, at that size, you have all options on the table (CK, GK, FSR, Sugery, etc..), but with radiation treatments there is a very real risk that the tumor will increase in size before hopefully it shrinks and dies. Given that the facial nerve is being affected by it's current size, that gives me pause in thinking what might happen if it swells due to radiation.
Hearing results after surgery? Yeah, I didn't have much going into surgery and came out SSD (single-sided deaf) on that side as expected.. I think I was given a snow ball's chance in... well, you know for my hearing. So, I expected to be SSD after. The good news is that you will either adjust to being SSD if that happens or you have options (BAHA, TransEar, Ponto Pro, SoundBite, etc..). It won't be like 'normal' hearing, but it supposedly does help quite a bit..
Anxiety level? Looking back, I was a bit anxious about the surgery leading up to it (thankfully, I only had to wait less than 1 month between diagnosis and surgery) but there generally comes a time just before treatment where you become eerily calm and ready to just get it over with and start the healing process. You kinda get into a mode of gearing up for it; kinda like gearing up for a sports game, or fight or something... You're nervous leading up to it, but there comes a time when you decide you've done all you can, did your homework and due dilligence and you place your trust into the hands of God (if you believe) and your doctors treating you.
With surgery, as with any treatment, there may be bumps in the road after treatment during the healing process, however you generally can get through them with the help of family, friends and us here on the forum especially those who have gone before you. Our collective knowledge of what to expect, what to do for certain things, how to handle certain things, etc.. is unmatched ANYWHERE. The shared knowledge we all have of AN treatments and recovery is better, in my opinion, than even the doctors who treat you. While they've learned about it from books and treating patients, we've all lived it and are more than willing to share our knowledge..
So, what's the next step for you?
