Answer 3

T

Question 4

Fat graft in obese patients yeld excelent result. T or F

Answer 4

F. the viability of the fat is actually compromised in obese patients.

Question 5

Patient factors such as age have been found to have an impact on fat graft viability,

Answer 5

T

Question 6

Although some studies demonstrated the greatest yield and viability of adipocytes from the medial thigh, but there are no differences between different site of the body

Answer 6

T

Question 7

syringe aspiration and centrifugation of the fat. Most studies examining this process found this technique to be simple and atraumatic to the adipocytes

Answer 7

T

Question 8

In fat grafting there are always risks of fat necrosis as fat retention following fat grafting is never 100%

Answer 8

T

Question 9

excellent volume retention, efficacy, and safety of
autologous fat grafting for breast cancer patients without increased
risks of recurrence

Answer 9

T

Question 10

Studies examining the wetting solution demonstrated a negative
impact on adipocyte viability with the use of lidocaine

Answer 10

T

Question 11

Studies examining the wetting solution demonstrated a negative
impact on adipocyte viability with the use of lidocaine

Answer 11

T

Question 12

aspiration via
handheld or with mechanical suction and centrifugation have little
impact on fat graft viability

Answer 12

T

Question 13

injection via slow, controlled pressure to minimize the shear stress and forces on adipocytes does improve adipocyte viability

Answer 13

T

Question 14

most valuable
components of the lipoaspirate is the stromal cell fraction containing
the adipose derive stem cells and other pluripotent stem cells that
can enhance tissue recovery or augment fat graft take.

Answer 14

T

Question 15

no unbiased studies are available that have
demonstrated superior outcomes compared to the traditional handheld syringe aspiration and centrifugation technique

Answer 15

T

Question 16

here are always risks of fat necrosis as fat retention following fat grafting is never 100%.

Answer 16

T

Question 17

percentage of viable adipocytes following
fat grafting, but range from 50% to 70%

Answer 17

T

Question 18

palpable mass after fat injection indicates what?

Answer 18

oil cysts or fat necrosis

Question 19

fat graft should always be injected without excessive force and always
while withdrawing the cannula to avoid fat empolization

Answer 19

T

Question 20

lipofilling to be a safe and effective technique in breast reconstruction without any association with
breast cancer recurrence

Answer 20

T
