There are many unknowns in the treatment of hypertrophic scars and keloids, including the mechanism of their pathologic condition, and the means to resolve them. Therefore various treatments are being tried. We used silicone cushions in the treatment of hypertrophic scars and report our experience of this potentially useful clinical approach.
Silicone cushion consists of dimethyl-poly-siloxane silicone rubber with a methylphenyl base. Our subjects were patients with hypertrophic scars, and our evaluation was based on the report by Hirshowitz et al. Objective findings and subjective symptoms were scored and the degree of improvement evaluated. The presence or absence of adverse reactions was also evaluated.
Owing to use of the silicone cushions, all subjects showed clinical improvement. These cushions—enclosing high-viscosity silicone oil within the silicone capsule—are designed to generate a static electrical field with a negative charge. It has been suggested that static electricity plays a role in the involution of hypertrophic scars, and that the generation of an appropriate and sustained static electrical field is necessary to attain a useful clinical effect. Here we present a description of our cases, together with a discussion.
