Usually, the flank is considered a separate area from the bra strap when thinking in terms of liposuction. This would be up to your surgeon though.
You should consult a board certified plastic surgeon. VASER lipo can be used to meticulously remove fat from the areas that are bothering you. The Gold Standard for superior liposuction results requires use of the advanced technology of ultrasound assisted VASER liposuction. As an official trainer of VASER liposuction, I perform full body liposuction cases every week. VASER liposuction has been the only modality that has consistently resulted in outstanding liposuction outcomes. VASER liposuction ensures a smooth contour regardless of degree of excess fat by virtue of being able to remove any and all remaining fat comprehensively and uniformly. If skin redundancy is observed, Renuvion technology can be simultaneously applied to tighten your skin to optimize your overall contour outcome. A Skype or FaceTime consultation with a VASER specialist will help you get an accurate recommendation and pricing.Respectfully, Arian Mowlavi MD, FACSRealself 100 Hall of Fame Inductee
