Hi Lisa M and welcome to this Forum of caring, supportive new friends ......
First of all, take a deep breath and do not be in a rush to decide on treatment.
HEI is well established as an excellent facility in the treatment of acoustic neuromas so you are in good hands. Their specialty is surgical removal and as such, have had hundreds of success stories. All of the docs there have excellent reputations. Someone else may be able to tell you more about Dr. Slattery specifically. (As a side note here: I am scheduled for translab surgery with Dr. Friedman and Dr. Schwartz at HEI on May 11th so I can tell you more a month from now.
) What was told to me is that they work in teams at HEI of one otolaryngologist and one neurosurgeon. Each has specific responsibilities during the surgical removal. My assumption is that these responsibilities may change with the type of approach being used. The decision for the type of approach used is determined by many factors ..... size of AN, specific location it is growing, current hearing loss, and patient/doctor preference.
I am a little puzzled why Dr. Slattery said your tumor was too big for radiation. Generally speaking tumors under 3 cm are potential candidates for radiation treatment. Perhaps it is the specific location of your AN, but you might want to ask some questions.
This is my second go-around with surgery for AN removal. My original AN was 2.6 cm and was surgically removed via retrosigmoid approach at Duke University. Unfortunately I fell in that 5 to 9% of retrosigmoid surgeries that resulted in regrowth. I had 80% of my hearing going in to that surgery, came out with 20% (but with 100% speech discrimination, meaning a hearing aid has boosted it successfully for one on one conversation).
If you have not already done so, send for the free ANA brochures. They contain a wealth of information and much reassurance. See: http://www.anausa.org/index.php?option=com_aicontactsafe&view=message&layout=message&pf=4&Itemid=195
There are many other resources on the home page you might want to check, as well ..... questions for physicians, etc.
Best wishes in this fact-finding, decision-making phase. Let us know how you are doing.
