Abstract submitted for the 5th International Keloid Symposium
Keloid is a benign skin tumor caused by excessive proliferation of fibrous tissue and an imbalance in extracellular matrix (ECM) metabolism. It has a tendency to grow outward and is prone to recurrence, often accompanied by functional or aesthetic complications such as pain and itching. In addition to patient heterogeneity, trauma, inflammation, and tension are important factors contributing to keloid formation. Currently, comprehensive surgical-based treatments remain the primary approach. Reducing wound tension is critical to preventing abnormal scar hyperplasia. Therefore, preoperative design parallel to Langer’s lines (anatomic tension lines) or the use of S-shaped incisions, combined with tissue expanders, can reduce mechanical tension. Common intraoperative techniques include V-Y plasty, Z-plasty, W-plasty, local flap transfer, intradermal sutures, and specialized tension-reducing suturing methods. Postoperative strategies involve skin tensioners, wound tapes, adhesives, mechanical closure devices, non-invasive adjustable tension systems, and pressure therapy. However, enlarged surgical wounds and prolonged operative time increase surgical complexity, risks, and healthcare costs.
Keloid Trephination Technology involves using a skin punch to extract keloid tissue in situ via volume reduction, drainage, and tension balancing. This technique is characterized by its in-situ precision, minimally invasive nature, and suitability for clinical adoption and development.
