Forget facelift and tummy tuck, bum lift is the latest cosmetic craze!

Facelift and tummy tuck will soon become passé, for more and more women are opting for the trendier bum lift.

Constantino Mendieta is the inventor of the Miami Thong Lift, the latest way to a shapelier rear view.

According to Mendieta, a Harvard-educated surgeon, there has been a steady rise in the number of women seeking a curvier bottom like that of Miami's famous resident J-Lo aka Jennifer Lopez.

But top-notch plastic surgeon Rajiv Grover explained that these operations could be risky.

Previously, the standard way to create a rounder, higher bottom was with silicone implants, similar to those used for breast enlargement.

"Implants have a tendency to move and, if they get infected, they have to be surgically removed," The Daily Mail quoted Grover as saying.

So, Mendieta used grafts of fat liposuctioned from the thighs or stomach, purified and then painstakingly injected — using a large needle — into the layers of muscle of the buttocks, changing their shape from flat to super-curvy and high.

Because the fat belongs to the patient, there is no risk of rejection.

The scars left by the incisions needed to inject the fat are hidden, said Mendieta, 'in the grand canyon where the thong goes', hence the name of the procedure.

But he, too, warned that the procedure is not entirely risk-free. "It needs to be done by a very experienced surgeon, in a hospital, in sterile conditions with good aftercare — if you get an infection it could cause a very large abscess," he said.
