Background: Mechanically offloading or shielding an incision significantly reduces scarring in both animal and first-in-human studies. Whether or not this strategy would be effective following scar revision surgery was previously unknown. In this article, the authors report that the embrace device, which uses principles of mechanomodulation, significantly improves aesthetic outcomes following scar revision surgery.

Methods: A prospective, open-label, randomized, single-center study was conducted to evaluate the appearance of scars following revision and embrace treatment. Revision surgery was performed on 12 patients, each acting as his or her own control, and outcomes were assessed at 6 months. A visual analogue scale was used to evaluate each scar, rated by four independent surgeons who were not involved in the study.

Results: Evaluation of 6-month scar images by four independent surgeons using the visual analogue scale demonstrated a highly significant improvement in scar appearance following embrace treatment (p < 0.005).

Conclusion: The embrace device represents a powerful new technology for significantly improving scar appearance following revision surgery.
