Plastic surgery and Botox are two different things.
I was attacked by a dog when I was a small child in the somewhat early years of plastic surgery. I wound up getting 78 tiny stitches in my face.
If my accident had happened just a few years earlier, or the surgeon had not been there, I would have lost an eye and had to live my life with a very disfigured face. I was very fortunate: the scar in the corner of my eye is nearly invisible, and the gaping hole in my cheek is only minimally visible.
I owe a large debt of gratitude to that surgeon. He worked on my face for hours, and I was his 2nd long surgery that day.
I was a small child, and it was excruciating for me to hold still while my eye was being sewn with a needle. Because it was my eye, they had to keep me awake with only a local anesthetic that only partly numbed the skin by my eye. I still felt every stitch. The surgeon kept begging me not to cry, over and over. Promising he'd be done faster if I could keep from crying. That's what I remember most. Holding back my tears. When it was all done... I got to have a BIG MAC from McDonalds!
Meanwhile Botox is now being used to treat a wide range of medical conditions. Including muscle spasms, migraines, and lazy eye. As in an older relative of mine had a major stroke. He lost use of his leg, and suffered daily painful muscle spasms. Botox in his leg helped ease his pain a great deal when nothing else worked.
Alas, I've always liked Bambi's friend Thumper.
