Treatment of Hypertrophic Scar with the Silicone Cushion

Aim: Various treatments for hypertrophic and keloid scars have been attempted including electron beam irradiation, local triamcinolone injection, oral tranilast administration, use of silicone sheets, and compression therapy using splints. Among them, we have been attempting silicone cushion patching on hypertrophic scar. Methods: Twenty cases (10 males, 10 females) with hypertrophic scar were treated with silicone cushion. Scar surfaces were kept in contact with silicone cushion for as long periods of time as possible every day. Results were assessed in scores using objective findings (redness, bulging, induration) and subjective symptoms (itching, spontaneous pain, tenderness). Results: As for objective findings, redness remained unchanged in one case, but bulging and induration were found improved in all cases. As for subjective symptoms, itching and tenderness were found improved in all cases and clinical course considered proving usefulness of the treatment was obtained. Conclusions: Silicone cushions have highly viscous silicone oil enclosed in the silicone pack designed to generate negative charge electrostatic fields. Generation of adequate and sustaining electrostatic fields is important for useful clinical effect to exhibit on hypertrophic scar recession. Generation of negative charge electrostatic fields was confirmed on potential determination data with an electrostatic field meter as well.
