Full-Thickness Skin Graft according to Surrounding Relaxed Skin Tension Line Improves Scar Quality in Facial Defect Coverage: A Retrospective Comparative Study

Figure 1

The schematic illustration of study design. We performed a wide excision of facial skin cancer and immediately performed a FTSG on the facial skin defect. Patients were divided into groups that underwent FTSG matching RSTL between donor and recipient and those who did not follow RSTL. In the RSTL-matched group, the graft was harvested at the donor site, trimmed according to the defect, and applied to facial defects in accordance with RSTL. In the RSTL-unmatched group, the harvested graft was applied to the facial defect regardless of the RSTL of the donor graft.
