LAUSR

Purpose The skin paddle of the latissimus dorsi flap is typically inset horizontally (HILD) in breast reconstruction. We describe our experience with the vertical inset of the latissimus dorsi (VILD) and its aesthetic benefit. Methods We performed a case-control study comparing the most recent cases of both VILD and HILD. Scar, as seen on anterior-posterior photographs, was digitally measured and compared from 3 clinically relevant areas: (1) all visible scarring (“mirror view”), (2) scarring above the nipple (“self-view”), and (3) scarring above or medial to the nipple (“social view”). Demographics and outcomes were statistically compared. Experience/Results Fifty of the most recent patients receiving HILD or VILD were selected for each group. Average patient age was 55.6 and 51.6 years (P = 0.32), and average follow-up was 531.6 and 606.7 days (P = 0.20), respectively. The VILD scar-length ratios were decreased by 17% in the mirror view (P ⩽ 0.01), 37% in the self-view (P ⩽ 0.01), and 37% in the social view (P ⩽ 0.01). There were no statistically significant differences between groups regarding smoking (P = 0.75), diabetes (P = 0.70), body mass index (P = 0.74), seroma (P = 0.46), infection (P = 1.0), or flap necrosis (P = 0.70). Conclusions The VILD is safe and reliable. Measurements from anterior-posterior photographs illustrate statistically significant decreases in overall scar burden (mirror view) and statistically significant reductions in the highly visible self-view and social view. Our study is the first to quantify a reduction in scar burden by using VILD technique.
