Thank you for sharing your story, Hampshire82! When we share our stories, that is when others can listen and benefit from them. When we keep our stories to ourselves, it helps no one. Welcome to the ANA Forums!
I'm glad you insisted on getting the MRI because that is what is vital in determining if it is a Vestibular Schwannoma. And I'm also glad you did not listen to the neurologist who told you that radiation was not an option because your tumor was too small. As you found out, it is when a Vestibular Schwannoma is too large, that surgery is the only option. When it is small enough, there are three options: surgery, radiation, or waiting and monitoring. And all options are valid (even though many on the forums will have their preference for what is best).
In terms of what you were told about the tinnitus dying down after the tumor shrinks and dies, I am afraid to tell you that that is not usually true. Many have surgery where the tumor is completely removed and still have tinnitus. Others have had the auditory nerves removed and still have tinnitus, Many have had successful radiation and still have tinnitus. While I do not want to burst your bubble, these forums need to convey accurate information, and I do not want other readers to think that if they have radiation therapy (or even surgery) that their tinnitus will lessen or improve. I don't want to state that it cannot, but that is not the typical experience.
Some have described it similar to an amputation. A person may no longer have an arm, but they still can experience phantom pain where their arm was. And when the Vestibular Schwannoma is removed surgically or is killed through radiation therapy, most people do not have a reduction in their tinnitus.
I do truly hope that your experience is an exception to the rule and that your tinnitus goes away completely. Mine is always with me, but I have learned to ignore it (for the most part). There are a number of potential 'treatments' for tinnitus (none of which I have found particularly successful for me), but it might be worth discussing options with your ENT. And if you find one which works for you, please share it on these forums.
I wish you the best in your journey, my friend, and I am delighted to hear that your tumor is dying and that the radiation treatment was successful!
