The American Society of Plastic Surgeons released its latest cosmetic and resconstructive surgery statistics on Monday. 

Many of the trends were familiar.  In all, the group reported, Americans underwent 1.6 million cosmetic surgeries, including face-liftsliposuction and rhinoplasty; 13 million minimally invasive procedures (think Botox injections) and 5.6 million reconstructive procedures (including tumor removal and scar revision).  People in the U.S. spent $11 billion on the cosmetic procedures alone.

Once again, for the seventh year in a rowbreast augmentation was the most popular form of cosmetic surgery, with 286,000 operations performed.  Botox treatments reached an all-time high of 6.1 million injections. People between the ages of 40 and 54 accounted for the largest portion of the cosmetic procedures: 6.8 million, or 48%. Ninety-one percent of cosmetic procedures were in women. 

But the society chose to highlight one procedure that is less familiar: the upper arm-lift.  In 2012, 15,457 patients, 98% of them women, spent a total of $61 million to have liposuction on their arms, or what's known as a brachioplasty (a surgery that involves making an incision from the armpit to the elbow, usually along the back of the arm, to remove excess skin).  The number of procedures was up 4,378% since 2000, when only about 300 women opted for it, the group reported.

In a statement, the ASPS said that doctors didn't point to a single reason for the increase, but took note of poll data indicating that women "are paying closer attention to the arms of female celebrities" including Jennifer AnistonDemi Moore and Kelly Ripa. The most-admired arms of all? Those of First Lady Michelle Obama.
