As the number of plastic surgeries performed in the U.S. continues to grow — there were 16 million procedures in 2007 — so do the number of people with regrets, according to a report in the Chicago Tribune.

"I'd say at this point that one out of about every two or three procedures I do is a revision surgery," said Dr. Andrew Jacono, chief of facial plastic and reconstructive surgery at North Shore University Hospital in Manhasset, N.Y.
