Hiya! Been lurking for awhile. After three months of aggressively seeking treatment for my tinnitus, I am currently undergoing some therapy that will take time to show results. Meanwhile I've been reading about microvascular decompression of the 8th nerve and the success some patients have had in relieving their symptoms after this surgery. Some cases are discussed here: https://www.tinnitustalk.com/thread...-cures-some-peoples-tinnitus.1792/#post-15300. From what I've read, the "controversial" nature of applying MVD to tinnitus is that some studies have shown non-symptomatic patients with similar vascular compression to symptomatic patients. In fact, vascular compression has appeared in the asymptomatic ears of patients affected unilaterally. Some years ago I did some reading about male pattern baldness. Basically, some men go bald due to a genetically predisposed sensitivity to a by-product of testosterone. Men who don't go bald may not have that predisposition, or they may have insufficient levels of testosterone to produce the by-product in toxic amounts. Thus, it's a combination of genetic and other factors that create the condition. Could something similar be responsible for tinnitus in individuals with vascular compression of the 8th nerve? Could the compression be the basic cause, but depend on a genetic-or-environmental predisposition to produce its symptoms? That would explain why some people with vascular compression are asymptomatic. The genetic argument is harder to make regarding asymptomatic ears of unilateral sufferers; however, this does not rule out environmental factors. For that matter, might there not be a genetic difference between the two ears? I hope someone is pursuing this avenue of medical research. I've recently been reviewing the results of my MRI (it's not a tuumah) and am impressed by the amount of data that can be gleaned from this technology. Unfortunately, I have no idea how to spot abnormalities myself. The consulting neurologist gave me a clean bill of cranial health, but we didn't speak in person. I have no way of knowing if vascular compression is a diagnosis s/he would have considered, and I am weighing up the pros and cons of seeking a second opinion. Anybody know of ongoing MVD-VIII research? Any advice on getting a neurootologist to walk me through my MRI?
