Fat Grafting Flashcards
Locations of injections for fatgrafting to the face
- Midface
- Temporal fossa
- Periocular area
- Perioral area
- Facial lines
Microfat
Term coined by Tonnard, defined as fat harvested in small particle sizes utilising tumescent infiltration and small gauge harvesting cannulas (2.0-2.4 mm).
Utilised for facial volume restoration and preferred method for volumization.
Nanofat
Fat grafting derivate from emulsification of microfat. There are no viable fat cells in the nanofat solution.
Adipose stromal cells are preserved in nanofat preparations, have been credited for restorative skin effects seen with nanofat use.
Should not be used for volume enhancement, but as an adjuvant to skin quality improvement.
Principles of fat grafting in face
- Should be performed by avoiding bonus injections or the use of large particle sizes.
- Small harvesting (2.1-2.4 mm) and injection cannulas (1.2 to 0.7 mm) should be used.
- Microfat is used for volume restoration
- Nanofat is used for adjuvant to skin quality improvement
Technique to optimal fat intake
Time from harvesting to injection - crucial point for optimal fat intake. Quicker the fat injected after harvesting the better the result.
Preparation of fat through decanting, straining, washing or centrifugation procedures seems to be equally effective for fat survival.
Uses of fat grafting
- Scar treatment
- Providing thickness to soft tissues in cheek reconstruction
- Surgical option in treatment of velopharyngeal insufficiency as posterior pharyngeal fat grafting
- Treat postoperative deformities and deficiencies such as mild temporal hollowing following treatment of craniosynostosis.
- Soft tissue defect associated with hemifacial microsomia
- Donor site depression following flap transfer
- Fill deep wrinkles
- Lip volumization
- Cheek augmentation
- Breast augmentation and reconstruction including nipple
- Gluteal augmentation
- Penile augmentation
- Percutaneous aponeurotomy and lipofilling in Dupuytren’s disease
- Burn scars
