How can I treat fat necrosis two years after BBL?

Must obtain a scan of buttock initially to determine size of fat necrosis area. In my experience the method to improve is directed liposuction with small caliber cannula. then some lipo with nano fat graing to area. Expect fees in the $6,500.

Dead fat, unlike living fat, cannot be removed by liposuction, or removal of fat through a cannula by pressure extraction. The dead fat hardened by calcium must be removed in total through an incision in the skin, much like a cyst or a tumor is removed. If the removal is extensive, reconstruction with additional fat grafting may be necessary as well. Thus, the issue of fat necrosis requires an expert skill set to create the optimal result. The goal is both optimal removal of the dead fat while sparing any living adjacent tissue to minimize the overall defect and allow for the best possible reconstruction.

You have basically two options:
One is to inject steroids into the lump; up to three injections 4-6 weeks apart
Two, excise the lump under local anesthesia.
