What is the name of the procedure to remove the fat at armpit (underarm)?

I frequently have patients wanting to address fat near their armpit. Excess fullness on the front fold of your armpit - the kind of fullness that hangs out in tank tips- is typically fat; this can usually be treated with a small amount of liposuction. Sometimes this area can also contain glandular tissue (and stretched out skin), and so excision is usually needed for optimal benefit. 
Some patients are looking to improve the fullness in the bra roll area, below their armpit, on the chest wall. This fullness is usually within the bra band but can create a bulge and can make it more difficult to place one's arm flat against one's side. I commonly address this area at the same time as a breast lift or breast reduction be carrying the incision underneath the breast further back. 
Because the adjacent glandular breast tissue, this wouldn't be my preferred area for "obtaining fat" for fat transfer purposes. 

Hello and thank you for your question. The simple answer to your question is it can very likely be taken care of. Whether its fat or breast tissue it can be either liposuctioned or removed. The best way to give you the best surgical plan is to evaluate you in person. Please make sure you are being evaluated by a board certified plastic surgeon! Wish you the best of luck! Ankur Mehta MDBoard Certified by The American Board of Plastic SurgerySugar Land, Tx

Some patients will have extra tissue in the armpit (axilla) which is not just fat.  I would have to examine you to make a recommendation about the best procedure.  Liposuction or excision may be reasonable.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA
