Does fat transferred to hip dips during BBL survive?

Thank you for your question. Yes fat can survive in this area but the amount varies from person to person. I would recommend an in-person consultation with a board certified plastic surgeon. 

About 60% of fat from the transfer is retained and the results are permanent. The size will change with your weight just as the rest of your body does. In other words, the fat acts like it was naturally there. You can get a good idea of the final result after 6 months.

hello thank you for your question and provided information as well..Based on the exposed case, the bbl and the fat graft in the hips go in a combination as it helps me to shape the body more and give it a better shape, as to the amount of time it can survive, the fat is unpredictable, but in my cases it may reabsorb as 30% but it is not significant or visible.

The fat well placed and prepared definitely stays in the butt and the hips. We always perform the BBL not only shaping the whole torso with a thorough liposuction but also enhance the hour-glass shape with fat transfer to butt and hips.

Thank you for your question!. It is impossible to say how much fat is going to remain after fat grafting. The best is to wait 3-4 months to evaluate how much is still remaining, because if after this period is still there, is most likely to persist (meaning it has blood supply).
Remember to always seek for a board certified plastic surgeon to help you in this matter!.

Hi. Yes, is true, it does survive but in a rate of only a 80% of the grafted fat. Because there is poor vascularity in that area, and where there is poor vascularity there is poor integration of the transfered fat.

Hip dents are related to "zones of adherence" where the skin is more tightly attached to deep structures.  Grafted fat should survive in hip dents similar to other body areas, but skin attachments to the deep structures may interfere with the final result.  As long as patients understand the limitations of fat grafting, I think it's a reasonable area to treat.
When fat is harvested during liposuction, the technique must as minimally traumatic to the fat cells as possible to ensure survival.  Many surgeons believe the purification of the fat, whether via a centrifuge, straining or decanting technique is a critical step.  When fat is injected into the new area, specially designed cannulas are used to maximize fat transfer survival.  After surgery, avoiding pressure on the grafted areas will help fat transfer "take."
Theses are my general thoughts and an in-person consultation would be needed for your specific situation.

If the fat is adequately prepared and placed within a good location, it should survived similarly to fat placed elsewhere.  Please see a board certified plastic surgeon who may best be able to assure you safety and quality.
