Etymology
Examples
1996
To Sevinor, other reasons for cosmetic surgery are equally suspect. Some people, for instance, are hyper-perfectionists: "They'll point to a line or wrinkle that I have to put on my magnifying glasses to see. I'll never make that patient happy." Some are teen-agers who, believing themselves unpopular, look to facial surgery as a quick fix.

Some are patients Sevinor dubs "surgiholics," who "start at the top, work their way down, and repeat everything. No matter how many procedures they have, it's not enough."

1994 (earliest)
Choosing the appropriate patient is as important as selecting the correct procedure. Physical appearance is one clue to determine whether he or she is a good candidate. Is the patient disheveled? Does he or she have a defect which is only minimal? Has the patient already had a number of plastic surgery procedures performed? In other words, is he or she a plasti-surgiholic?

Notes
The earliest citation for this blend of surgery and the suffix -aholic (meaning, "one who appears to be addicted to something") is actually a variation on the word.
