fat graft for ultrafine injection. Hee Young, Lee M.D., Hyun Jin, Yang M.D. BaroYL & Kangnam Plastic Surgery, Seoul, Korea
The
clinical results of fat graft depend on the doctor’s techniques. Micro graft
and high stem cell density would increase volume maintenance. Beside of volume
maintenance, precise injection skill is so important especially in periorbital
area because of thin skin and small space to inject. We have been developed for
10 years to make every graft sizes smaller to be used with fine needle and to
increase stem cell density at the same time. Moreover than these, ECM density directly
mean more growth factor, more collagen and more stem cell induction from
recipient areas. Rapid vascularization would reduce down time one of main
interesting of patients. We used licensed medical cutting mill (Filler Geller TM.
Medikan, Korea.) for micronization and removal of lipid of fat tissues at operation
room. These fine fat tissues still have dense
living stem cells, so cell density is increased 3 times than normal fat
tissues. We can use 26 to 30 gauge needles like fillers in which the size of
every particle is under 0.2mm in maximum diameter. However, this process will
reduce total fat volume around to 10-30% that means loss of harvested volume.
So, we usually use this only for periorbital areas, nasal tip, fine wrinkles.
Sometimes we use this ‘fat gel’ to treat for wound healing of skin defects,
ligaments injuries, suture wounds. We anticipate it could reduce possibility of
fat embolism in the face that can cause skin necrosis, blindness, cerebral
infarct. We
reported ‘fat gel’ as more condensed fat tissues in the aspect of ASCs density
per graft volume, and ‘ASCs + scaffolds’ injection as a useful method for small
volume augmentation even though statistics calculating exact volume maintenance
are not enough. All
results were better, no complications we have been found over 10 years,
thousands of cases. |
