[Effect of subcutaneous tissue trimming on the survival skin area of avulsion skin flap].
OBJECTIVE
To investigate the effect of subcutaneous tissue trimming on the survival skin area of avulsion skin flap.


METHODS
Degloving injury was created in bilateral hind limbs of 7 pigs with avulsion injury machine, 4 cm x 10 cm avulsion skin flaps were elevated in degloving areas. Skin flaps in one side were replanted as control without any treatment. Subcutaneous tissue in the skin flaps of another side was partially excised and replanted by trimmed skin flaps. Survival skin flaps was calculated with computer at 7 days after operation.


RESULTS
In the control group, the survival skin area was (40.41 +/- 9.23)%, while in the experimental group, the survival skin area was (60.90 +/- 15.26)%. There was significant difference between the two groups (P < 0.05).


CONCLUSIONS
Trimming off subcutaneous tissue does improve the survival area of avulsion skin flap.
