Collagen lays down prematurely
7. Research Questions
Is there value in using silicone gel products with post-surgical wounds to enhance scar pliability and visual appearance?
One product better than another?
8. Silicone Gel Mechanism unknown
Borgognoni (2002) says silicone induces hydration of skin surface
Brissett (2001) says silicone decreases capillary action, inflammatory mediators and collagen production
Nikkonen (2001) found silicone gel reduced hypertrophic scarring
9. Silicone Gel and Hypertrophic Burn Scars Examine application of silicone gel sheets affected blood flow in burn scars
Vancouver Scar Scale
No change in blood flow
Increased surface temperature
Musgrave et al (2002)
10. Silicone versus nonsilicone gel dressings: a controlled trial. To compare silicone and nonsilicone gel dressings in treatment of scars
Scar size, hardness, symptoms, color
All measured parameters were significantly reduced
Silicone and nonsilicone equally effective
