Hey guys, I'm new here. Just found this tonight. In short, I've had severe, unrelenting pain X 3.5 yrs. Tried: Botox, accupuncture, nerve blocks, and last Sept 2006 I had the "keyhole" approach surgery. Didn't work. But it didn't harm my facial movement. This is the first place I've heard my "endoscopic neurectomy of the 5th trigeminal nerve" called the keyhole approach. Has anybody else had this? Thanks.
