If I were your age, and considering your hearing is gone, I would want the thing out. Then chances are very great, especially because it is small, that you can get on with your life and not look back. You will have a great surgical team and they do thousands of these surgeries. For an older person like me, radiosurgery is a better option. Older bodies don’t heal as well. But for you, having it removed so it is gone seems the best choice. The important thing is to make the decision you are most comfortable with and go with it.
