Is there any information about lipo of the outer arm?

Lifts on this famously wobbly part of the human
anatomy—known familiarly as “Hi Janes” or “Bingo” arms—are particularly
popular. Heavy and even moderately droopy arms can be recountoured very
effectively with liposuction. Liposuction modifies volume by sucking out fat
and because liposuction stimulates the skin to tighten, good elasticity
provides a smooth contour after fat is removed. The procedure takes about an
hour, the recovery takes just a couple of days, and there's virtually no
scarring. I use several innovative forms of liposuction, including SmartLipo,
in order to contour and resculpture the area while providing the most beautiful
results with minimal scarring. SmartLipo, used in combination with other forms
of liposuction or alone, is a procedure that uses laser light to liquefy fat
and tighten the surrounding skin. Liposuction as an outpatient procedure under
I.V. sedation can easily reduce the bulge that some people have in their arms.

A physical examination is necessary to determine the amount of fat and the elasticity of the skin before proposing liposuction as a procedure for contouring the arms.  If the fullness of your upper outer arm is from fat (and not muscle) then liposuction could be a possible method to improve the contour to your desire.
