I can identify with so much of what Saaz says . . .
I will be 70 by Christmas; have suffered TN for 30+ years; and had my first MVD 14 years ago. Unfortunately, that didn't work - but, for anyone undergoing a MVD now, the technology has massively changed since then!
It is in the past that a first MVD didn't work for me . . . and the surgeon wasn't interested in his 'first failure' . . .
I then found a really good consultant in Bristol (UK) who gave me 2 RF rhizotomies over the next couple of years and, with some help from gabapentin, kept the TN pain at bay for almost 13 years . . !
The pain attacks then returned however - and that consultant had retired.
I searched out his successor and, after another two RF rhizotomies didn't help, I had my 2nd MVD 6 months ago.
Based on a pre-op MRI, the main purpose of that was to undo what the previous surgeon had managed to achieve . . .
So, although I now share the experience of Saaz in terms of full left side numbness, tightness, fat face feeling, burning sensation (sometimes), and tingling sensations everyday . . . I am free of the 20 or 30 excruating attacks of TN pain which, every day, immediately pre-op, would literally see me on the floor screaming in pain . . . !
None of us want to suffer from TN but that, for me, has to be an acceptable trade off . . .
If it is any help to Amy, my surgeon told me to tail-off my medication (gabapentin + tegratol) from the day I left hospital. I was up to 2700 mg gabapentin per day and it has now been down to zero for several weeks! The withdrawl symptoms are not fun but they do pass . . Problems with my eye and ear disappeared after a few days . . .
Several people have mentioned sinus problems . . and I can add myself to that group . . . but again, an extra box of tissues each week is a cheap price to pay against the TN pain attacks . . .
Overall, escaping TN pain does involve a trade-off but I, for one, am grateful that such a trade-off is possible! :-)
