Cosmetic surgery corrections for minor defects or "imagined ugliness" are unlikely to produce results which satisfied the patient's perceived needs, says Dr Steven Kisley, associate professor of psychiatry at the University of Western Australia. ...

People seeking cosmetic surgery are six times more likely to have psychological distress than those with medical reasons.

"This condition is called dismorphic [sic] concern, or in layman's term imagined ugliness," Dr Kisley says. These people have a minor defect, but it still creates huge amounts of distress and increases the extent to which they withdraw from social contact.

The condition, known as "body dismorphic disorder," is characterized by obsession with an imagined flaw: An overly large nose, "devious-looking" eyebrows, a "stretched" mouth or undersized genitals are common examples. It can last for years, often accompanied by severe depression, suicidal behavior, social withdrawal, repeated visits to plastic surgeons and "frequent mirror checking."
