Typical steps are harvest, processing (washing, centrifugation or filtration) and injection in small aliquots. Part of the graft is resorbed, so results may require more than one session. Risks include lumps, oil cysts, calcification, asymmetry and, rarely, infection or fat embolism.","official_url":null,"image_url":null,"country":null,"region":null,"wikidata_id":null,"wikipedia_url":null,"verified":false,"scores":{"authority":74,"trust":0,"citation":0},"topic":{"slug":"fat-grafting","name":"Autologous Fat Grafting"},"url":"https://worldwiki.io/entity/autologous-fat-grafting","facts":[{"id":34,"predicate":"steps","label":"Steps","value":"Harvest by liposuction → processing (washing/centrifugation/filtration) → injection in small aliquots","unit":null,"confidence":100,"valid_from":null,"valid_until":null,"verified_at":"2026-09-14 13:42:07","source_ids":[16]},{"id":35,"predicate":"risks","label":"Common risks","value":"Lumps, oil cysts, calcification, asymmetry, resorption; rarely infection or fat embolism","unit":null,"confidence":100,"valid_from":null,"valid_until":null,"verified_at":"2026-09-14 13:42:07","source_ids":[16]}],"relations":[{"type":"related_to","confidence":100,"target":{"id":16,"slug":"fat-graft-survival","name":"Fat Graft Survival","type":"concept","description":"Fat graft survival (retention) is the share of transferred fat volume that remains after healing; part of every fat graft is resorbed, and reported retention varies widely by technique, site and how it is measured.","url":"https://worldwiki.io/entity/fat-graft-survival"}},{"type":"uses","confidence":100,"target":{"id":20,"slug":"autologous-fat","name":"Autologous Fat","type":"concept","description":"Autologous fat is a person's own fat tissue, harvested by liposuction and used as a natural filler or graft material in the same person.","url":"https://worldwiki.io/entity/autologous-fat"}},{"type":"uses","confidence":100,"target":{"id":30,"slug":"liposuction","name":"Liposuction","type":"medical","description":"Liposuction is surgery that removes fat from under the skin with a suction cannula; it reshapes body areas and is also the harvesting step for fat grafting and SVF.","url":"https://worldwiki.io/entity/liposuction"}}],"questions":[{"slug":"where-is-fat-harvested-from","question":"Where is the fat harvested from for fat grafting?","intent":"informational","language":"en","short_answer":"Fat is usually harvested by liposuction from the abdomen, flanks, thighs or buttocks, chosen by the amount of fat available and the patient's contour goals.
