Seventy percent of U.S. plastic surgeons have used fat grafting techniques for breast operations, but they are more
likely to use it for breast reconstruction rather than cosmetic breast surgery, reports a survey study in the July issue
of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons
(ASPS).
Once discouraged, fat grafting to the breast is an increasingly common plastic surgery technique, according to the
new report. But more data is needed to optimize the technique and outcomes of fat grafting for breast
reconstruction, according to a published report from a team led by ASPS Member Surgeon Dr. J. Peter Rubin of
University of Pittsburgh and Russell Kling.
High Rate of Fat Grafting for Breast Surgery…
The researchers surveyed the ASPS membership regarding their use of fat grafting for breast surgery. In recent
years, there has been renewed interest in techniques using the patient's own fat for cosmetic and reconstructive
breast surgery. In these procedures, the surgeon uses liposuction to obtain fat cells from one part of the body—such
as the abdomen or thighs—and uses it for augmentation or reshaping of the breast.
Four hundred fifty-six ASPS Member Surgeons responded to the survey. Overall, 70 of the plastic surgeons reported
ever performing fat grafting to the breast.
Eighty-eight percent of plastic surgeons who currently perform fat grafting to the breast said they use fat grafting
for breast reconstruction techniques, and often apply fat grafting along with implants or flap procedures. The
surgeons found fat grafting particular useful for improving the shape of the breast, including reconstruction after
"lumpectomy" for early-stage breast cancer.
Three-fourths of surgeons performing fat grafting reported that the abdomen was their preferred site for obtaining
fat for the procedure. The survey also provided information on techniques of harvesting and processing fat cells.
…But Potential Obstacles to Fat Grafting Techniques Noted
There is a long history of debate over the use of fat grafting for plastic and reconstructive surgery of the breast. In
the late 1980s, ASPS issued a strong statement against the use of this technique, citing the risk of difficulties in
early diagnosis of breast cancer. However, more recent studies have reported that fat grafting to the breast provides
very good results. Those studies also reported that changes seen on mammograms are easily distinguished from
abnormalities related to breast cancer.
As with any surgical treatment, risks must be considered. The plastic surgeons responding to the survey viewed
issues of interference with mammography and cancer screening as potential obstacles to fat grafting. Others cited
problems with unpredictable results, including poor retention of the transplanted fat cells.
Despite these concerns, the new survey suggests that fat grafting to the breast is an increasingly popular procedure
among U.S. plastic surgeons. Nearly 90 percent of the surgeons performing this procedure use fat grafting for
breast reconstruction, with a smaller percentage also using the procedure for cosmetic breast surgery.
The study provides useful "benchmark" data on the current use of breast fat grafting by U.S. plastic surgeons. Dr.
Rubin and colleagues cite the need for further studies to establish optimal techniques for maximizing fat graft
retention and patient satisfaction with the results. "This study shows the increasing popularity of fat grafting to the
breast, especially to benefit patients undergoing reconstructive procedures. As this field evolves, plastic surgeons
will better understand the factors that lead to the best long term outcomes," says Dr. Rubin.
They write, "This standardization may also increase the potential applications of the technique and may lead to
increased prevalence in clinical practice."
