Is it possible to do a breast fat transfer if you have small breasts and are thin?

Yes, skinny patients are the
best candidates for breast augmentation via fat transfer. At MBC, we use the “palm measure” to estimate the area and
the amount of fat to harvest. Using this method, out of a “palm measure” (the
average size of male surgeon’s palm) a thin layer of fat can be harvested out
of a large surface area, such as a thigh. Even in thin and petite women, we
have easily obtain 200-300 mL out of one portion of the thigh. We recommend
patients not to gain weight prior to the procedure, since it is preferable to
harvest and transfer smaller fat cells. These smaller fat cells are consistent
in size and result in a long lasting breast augmentation. The volume of fat
cells does not increase with weight gain, the fat calls become larger oil bags.
In a thinner patient, there are more fat cells in the same amount of fat than a
heavier woman, resulting in a more stable breast augmentation.

Fat transfer to the breasts can yield very good results even in thinner patients.Kenneth Hughes, MDBeverly Hills, CA

While some surgeons cling onto the notion that this is a worthwhile procedure, the results I gave seen both in the literature and personally have convinced me that it is a waste of time and money.  Brest implants are much more reliable.
