Xenoula...I would do some serious research before making your decision. With a 1.4cm you have all the options available to you. Translab would remove the tumor with little chance of facial problems, but perhaps other side effects, theres the gamma knife you were told, there is the cyberknife, etc. I spent 5 months researching before I decided on the Translab approach, which I thought best for me and my circumstances. Get a second opinion and then shop around. Its already been mentioned but go with the top guys you can find (who will take your insurance, even if you have to travel to get to them.) I was fortunate and had a top notch experienced pair of surgeons in Kansas City where my kids lived so coming here was no big deal. A lot of people here go to House Institute in California where everyone is top notch. Now is the time to say to yourself "OK, I've got this problem, now lets do some research and see how to take care of it!" Everyone on this site has been where you are, and they will, I assure you, give it to you straight without sugar coating and then add a little love and comfort to ease the pain.
Good luck, but research before making a decision. These are really slow growing tumors. You have time to make a decision.
