Ann Margret has Never had any type of surgery.
You know, that's not entirely accurate. She had that horrible accident back in the very early 70s - either in Vegas or Tahoe - where she badly damaged her face, and several of her limbs. I believe she was in a coma for a period of time. He face had to be partially reconstructed, and she did lose control of some of her facial muscles.
Lets not forget that Ann Margret, On September 9, 1972, while performing at Lake Tahoe, Nevada, she fell 42 feet from an elevated platform to the stage and suffered injuries including a broken left arm, cheekbone and jawbone. Smith flew a stolen plane from Burbank, California, to Lake Tahoe and back to get his wife to surgeons at UCLA for treatment, which included meticulous facial reconstructive surgery that required wiring her mouth shut and putting her on a liquid diet. Unable to work for ten weeks, she ultimately returned to the stage almost back to normal.[12]
