Triangular Flap Insertion: An Option for Correction of Dog-Ears Deformity in High-Tension Areas

Dog-ear deformity is a common protrusion defect of skin tissue after the closure of a surgical wound, affecting patients' appearance and quality of life. The common methods for correcting dog ears involve the removal of excess tissue in different directions or shapes after extending the incision along the long axis of the original wound. However, the literature regarding tissue preservation techniques for dog-ear correction is poor, especially for areas with insufficient skin tissue or high tension. The authors modified the original design of direct excisions, which transferred excess tissue from the horizontal axis of the wound to the longitudinal axis, thereby absorbing longitudinal tension and relieving linear scar contracture. This technique provides a way to correct dog ears without removing excess healthy tissue, especially as an option for dog-ear correction in high-tension areas.
