Liposuction can be performed through an old c-section scar. Of course, an exam is necessary to confirm that there are no hernias. Liposuction is performed through multiple small incisions that are about 0.5- 1 cm long at most.
Abdominal liposuction can be performed through the C-section scar. If you also need liposuction of the flanks or sides, sometimes additional, very small incisions will need to be made to achieve the best result.
