Effect of Transparent, Self-drying Silicone Gel on the Treatment of Hypertrophic Abdominal Scars - Full Text View

Purpose

Keloids and hypertrophic scars are a common subject of dermatologic consultations. Therapeutic management of such conditions remains challenging because of their high rate of recurrence and lack of curative treatment.

Primary Outcome Measures:

Scar thickness [ Time Frame: 1, 2 and 5 months after initiation of treatment ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Clinical assessment on overall scar appearance [ Time Frame: 1, 2 and 5 months after initiation of treatment ] [ Designated as safety issue: Yes ]

Estimated Enrollment:	38
Study Start Date:	January 2010
Estimated Study Completion Date:	June 2010
Estimated Primary Completion Date:	May 2010 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: Silicone gel Gel containing silicone gel	Other: Topical silicone gel Topical silicone gel will be applied to the scar twice daily for a period of 8 weeks Other Name: Dermatix gel
Placebo Comparator: Vaseline Gel containing petrolatum gel	Other: Vaseline Topical petrolatum gel will be applied to the scar twice daily for a period of 8 weeks

Detailed Description:

Silicone gel Sheeting (SGS) is one treatment modality that has proven effective for treatment of hypertrophic scar. One disadvantage of SGS is its application technique. To be effective, SGS must be applied on the scar for at least 12 hours daily. Topical silicone gel is a novel therapy that has shown promising result on scar prevention. However, the efficacy and safety of topical silicone gel for treatment of hypertrophic scar has not been confirmed.
