Official Title  ICMJE Influence of a Silicone Gel (Dermatix®) on Thoracic Scar Formation After Harvesting of Autologous Rib Cartilage for Standardised Total Ear Reconstruction
Brief Summary

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.

Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Cicatrix, Hypertrophic
  • Keloid
Intervention  ICMJE 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®
Study Arms  ICMJE Active Comparator: 1
Each patient uses the silicone gel on one half of the scar, leaving the other one blank as an internal control.
Intervention: Drug: Silicone gel (Dermatix®)
