Hi, Henry - and welcome ~
I also live in the Nutmeg State (Litchfield county) and had my AN debulking surgery and follow-up radiation at The Hospital of Saint Raphael in New Haven, back in 2006. Unfortunately, my radiation oncologist, Doctor Johnathan Haas, has relocated to Long Island but my neurosurgeon, Doctor Issac Goodrich, is still practicing in New Haven at Connecticut Neuroscience

not a doctor): as
Jay posted, losing your hearing with surgery is not an absolute, but it is likely. Although two of the three most-popular AN removal surgeries have the possibility of saving
some hearing, that cannot be guaranteed. Much depends on the exact location of the tumor and, as always, the surgeons skill. I don't know of any 'natural' method to improve your hearing or to rid yourself of the tinnitus but if the AN is irradiated, your hearing loss should be halted, although the possibility exists that it may deteriorate in the future, even with the radiation. These are valid questions to ask the radiation oncologist. However, my suggestion is that you reconcile yourself to diminished unilateral hearing in the future. Should your hearing ability stabilize, a possibility, you'll be pleasantly surprised. If it deteriorates, you'll be prepared.
The AN support group meeting should be informative. If you desire any further information regarding my AN experience (which was quite successful), just send me a PM and I'll be happy to respond.
