  Purpose

So far the evaluation of scar treatment was based on subjective criteria. The patient groups were divided into treated versus non-treated.

In this study we use patients undergoing ear reconstruction with autologous rib cartilage. The thoracic scar of harvesting the rib cartilage is routinely reopened after 3 month during second stage of reconstruction. Therefore we have a ideal model of clinical, physiological and histological scar evaluation in a homologous patient group.

All patients randomly treat one half of the scar with a silicone gel (Dermatix). The other half is untreated as an internal control.

Primary Outcome Measures:
  • Beausang's scar scale, skin elasticity (Cutometer®), skin moisture (Corneometer®), skin color (Chromameter®, Mexameter®), histological evaluation (HE, elastica, actin etc.) [ Time Frame: 45 minutes ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • allergic reaction compliance [ Time Frame: retrospective ] [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: January 2007
Estimated Study Completion Date: January 2009
Arms Assigned Interventions
Active Comparator: 1
Each patient uses the silicone gel on one half of the scar, leaving the other one blank as an internal control.
Drug: Silicone gel (Dermatix®)
The half one the scar to treat was randomised among patients. After regular cleaning of the skin around the scar one half was thinly creamed with the silicone gel from medial to lateral and let dry for 5 minutes. It was done twice daily.
Other Name: Dermatix®
