Good question.
Most people that are obsessed with their vanity have a dysmorphic disorder as well as OCD.
But cutters wanna cut, so a patient like that can always find someone who will do these cash-only vanity procedures, of course after the obligatory hold-harmless paperwork is signed.
Many such cases have terrible outcomes, so the patients just keep getting more surgery.
While legitimate plastic surgery for things such as trauma or congenital defects has merit, cosmetic surgery is not main stream medicine, and such a psycologic profile as you suggested should disqualify a patient from these procedures which simply play into their dysfunction.
For a little insight, watch episodes of “Botched”.
It’s 2 excellent plastic surgeons tackling cases with previous bad outcomes; some patients they see will simply never be happy, and they refuse to do those cases.
BTW, reduction mammoplasty for pathological enlargement is legitimate. There’s significant back pain and postural difficulties associated with this anomaly.
Bigger is not always better.
