A classification of clinical fat grafting: different problems, different solutions

Area of Science:

• Plastic Surgery
• Regenerative Medicine
• Tissue Engineering

Background:

• Fat grafting has evolved into a versatile reconstructive and cosmetic procedure.
• A scientific approach emphasizes recipient preparation, controlled harvest, efficient transplantation, and postoperative care.
• Despite standardized principles, variations in fat grafting techniques lead to diverse clinical results.

Observation:

• Four types of fat grafting cases were analyzed based on harvesting, cell processing, transplantation, and recipient site management.
• Key variables influencing outcomes included recipient site volume demands and tissue health (healthy vs. pathologic).

Findings:

• Case variations were noted across most analyzed variables.
• A classification matrix emerged, categorizing cases into small-volume vs. large-volume and regenerative vs. nonregenerative subtypes.
• Recipient site characteristics are the primary determinants of technique selection.

Implications:

• Fat grafting is a complex procedure with identifiable subtypes, challenging its perception as a simple technique.
• Recognizing recipient site differences allows for tailored fat transplantation strategies.
• Matching specific fat grafting techniques to distinct clinical problems ensures optimal patient outcomes.
