Breast Fat GraftingBreast fat grafting (fat transfer breast augmentation) uses the patient's own liposuctioned fat to modestly enlarge or reshape the breast without an implant.更新 2026年9月20日医疗
Facial Fat GraftingFacial fat grafting transfers the patient's own fat to the face to restore volume in areas such as the cheeks, temples and under-eye region.更新 2026年9月20日共同项
双方均有记录 2 项| 属性 | Breast Fat Grafting | Facial Fat Grafting |
|---|---|---|
| Definition | Fat is taken by liposuction from other parts of the body and injected to enlarge the breasts | Fat is taken from a donor area by liposuction, decanted, centrifuged or otherwise processed, and the purified fat is reinjected where volume is needed |
| US regulatory status | Following FDA guidance issued in November 2017, autologous fat grafts do not require premarket approval; stromal vascular fraction products receive closer review | Exempt from 21 CFR Part 1271 when tissue is removed from and reimplanted into the same individual during the same surgical procedure (21 CFR 1271.15(b)) |
各自的事实
仅在其中一方有记录的已核实事实。
Breast Fat Grafting
Typical donor sitesUsually the abdomen or flanks, though fat can be taken from almost anywhere (surgeon quoted by ASPS)
Typical size increaseSurgeon quoted by ASPS: ideal candidate wants half a cup to one cup; a larger increase may take two to three procedures
Listed risksCysts, infection, microcalcification, death of fat cells (necrosis), and some transferred fat leaving the breast area
Pre-expansion optionSurgeons may recommend an external tissue expansion system in the weeks before surgery
Pooled volume retention54% (95% CI 48.5–59.5%) across 25 studies, follow-up 3–36 months
Retention by fat preparation methodCentrifugation 51.5% vs sedimentation 38.7% pooled retention
Oncologic safety evidenceMeta-analysis of 15 studies (8,541 participants): no difference in overall survival, disease-free survival or local recurrence between patients who had fat grafting after breast cancer surgery and controls
1987 professional positionASPRS (predecessor of ASPS) condemned autologous fat injection for breast augmentation over concerns about cancer detection
2009 ASPS Fat Graft Task ForceConcluded that the literature then available showed no association between fat grafting and higher rates of malignancy
Relevant FDA guidanceSame Surgical Procedure Exception under 21 CFR 1271.15(b): Questions and Answers Regarding the Scope of the Exception
Suitable forPeople wanting a relatively small increase in breast size who have enough donor fat (ASPS)
SessionsMore than one session may be needed because part of the graft is resorbed
Imaging noteFat necrosis, cysts and calcifications can appear on mammograms and must be interpreted by a radiologist
Facial Fat Grafting
First documented fat graft1893: Gustav Neuber moved fat from the arm to correct scarring around the eye
Standardized techniqueSydney Coleman published standardized protocols for harvesting, processing and injecting fat (structural fat grafting) in the 1990s
Common facial usesFilling hollows under the eyes and nasolabial folds, repairing scars, enhancing the cheekbones, improving skin texture
Typical total facial graft volume10–100
Reported arterial embolism outcomesIn 61 published cases: permanent vision loss in all 26 with ophthalmic artery occlusion, neurological impairment in 8 of 10 with cerebral artery occlusion, and 6 deaths
No reversal agentHyaluronic acid filler can be dissolved with hyaluronidase, but no agent of comparable effect exists for fat emboli
Worldwide facial fat grafting procedures589,494 procedures; 7th most common aesthetic surgical procedure (ISAPS Global Survey 2021, as cited)
AlternativeDermal fillers (temporary, non-surgical)
Specific riskVascular occlusion when injecting near the eyes or nose (rare)
