FRIDAY, Oct 11 (HealthDay News) -- Beyonce, Kim Kardashian and
Jennifer Lopez have put ample backsides on some women's wish lists.
And what nature forgot, plastic surgeons can provide with a
Now, a small, preliminary Brazilian study finds that most women
who have the procedure are satisfied with their new look.
Experts caution, however, that some buttocks-enhancement
procedures -- especially when performed by unqualified people --
come with real risks.
The study technique involved liposuctioning excess fat where
it's not wanted -- such as from the hips and thighs -- and
injecting, or grafting, it into the buttocks to plump them up.
A good result "does not depend on a lot of fat infiltration,"
said study leader Dr. Rodrigo Rosique, a plastic surgeon in
Goiania, Brazil, but rather on the skilled method of combining the
liposuction and the injections. Avoiding large injections of fat
into any one area of the buttocks is key, he said.
"The degree of satisfaction is amazing, and it is overwhelming how the fat grafts [injections] really take into the patients' buttocks," said Rosique, a professor of plastic surgery at Federal University of Goias.
Rosique followed up on 58 women, aged 19 to 62, who had the
procedure done between 2010 and 2012. All but one patient reported
feeling very satisfied. The other patient had additional surgery
six months after her first one and then reported being satisfied
with the result.
Women whose weight changed by more than 10 percent after the
procedure were excluded from the follow-up evaluation.
"I took these patients out because the buttocks' final volume could be affected by the weight change, misunderstanding if the volume enhancement was due to weight gain or the graft," he explained.
Rosique is scheduled to present the findings Sunday at the
annual meeting of the American Society of Plastic Surgeons, in San
Diego. The research should be viewed as preliminary until published
in a peer-reviewed journal.
None of the study patients reported medical complications. Five
patients had a pocket of clear fluid that collected at the
fat-removal site, which was treated by draining it.
"The sculpting can give a very pleasing result," said Dr. David Reath, a Knoxville, Tenn., plastic surgeon who chairs the society's public education committee. He was not involved in the Brazilian study.
The procedure takes about two and a half to three hours, Rosique
said. Patients can return to work in about a week.
The researchers said avoiding the injection of large volumes of
fat in any particular site avoids the problems of tissue death. The
Brazilian researchers used an epidural anesthesia. In the United
States, Reath said, an epidural or a general anesthesia typically
would be used.
In the United States, plastic surgeons performed more than 3,700
buttocks procedures in 2012, including lifts and implants,
according to the society. The average surgeon fee for the
procedures is about $4,600.
Reath said, however, that patients should check carefully to see
if their doctors are qualified. Recently, a number of deaths have
been reported in the United States among women who have gone to
so-called "pumping parties," at which nonmedical-grade silicone is
sometimes used to plump up the buttocks and fill out facial
Unqualified persons inject the type of liquid silicone bought at
hardware stores. The fat solvent in the silicone can cause severe
problems, such as traveling to the lungs and obstructing the
"People can be disfigured or have worse complications," Reath said.
Deaths from illegal buttocks injections have been reported in
Alabama, Georgia, Florida, Pennsylvania, Nevada and New York. In
another case, a woman who reportedly went to a pumping party
arrived at an emergency room coughing up blood. Doctors found clots
in the small blood vessels in her lungs and discovered that the
injected silicone had traveled there and led to obstructions.
