Backgraund and objective.

The increase in bariatric surgery as an alternative to the treatment of both the metabolic syndrome and obesity and overweight leads to multiple bodily deformities, among these one of the most complex are mammary alterations. The surgical treatment of these alterations depends on an adequate diagnosis and a suitable technique able to reshape the mammary aesthetics.

The objective of this research is to define the importance of fat grafting as a procedure prior to breast-plasty in patients with post-weight loss.

Methods.

A retrospective and linear study was performed in 124 patients, who underwent 158 consecutive procedures between January 2009 and December 2019, age range between 18 and 72 years. The evaluated procedures allowed correction of different breast deformities such as hypotrophy or breast atrophy, ptosis, asymmetries, lateral positioning of the nipple areola complex, loss of the upper pole projection, skin flaccidity associated with persistent body lipodystrophy, previous body contour surgeries, and patient´s age and body mass index (BMI).

Results.

A total of 158 procedures were performed which the highest percentage was of triple flap interposition (28%, 44 procedures), followed by breast fat grafting (27%, 42 procedures) and triple flap interposition with silicone implants (19%, 30 procedures). The fat graft to breast was performed in 40.50% of the total procedures performed, with a mean infiltrated fat volume corresponded to 450.60 ml.

Conclusions.

We recommend performing fat grafts in all patients undergoing breast remodeling procedures after massive weight loss in order to volumetrically recompose the breast and rebuild skin, parenchymal and muscular structures, with breast fat transfer being the only way definitive filling of the upper pole. In addition, local flaps represent not only a form of volumetric augmentation of the breast but also a possibility of improving the breast contour and upper body segment.
