Figure 1. Excision design and results of a gingko flap. The excision line (blue line) is designed around a pigmentary lesion and a triangular flap design (while broken line), and an incision on the opposite side (white line) is added. The baseline length and height of the flap is 30–40% of the design length. After excising the lesion, a triangular flap is adapted to an incision on the opposite side. Therefore, a small triangular lesion is left on the suture line (lower photo). Possible dog ears are indicated by arrows. Because dog ear correction was not performed, the suture length of the gingko flap represents the final suture length. The remaining small pigmentary lesion and linear scar were finally resected by W-plasty.

Figure 2. Comparisons of the sizes of dog ears between the simple suture and gingko flap groups. The (dog ear height/design length) × 100% values in both groups were compared. The l/w ratios were divided into the categories indicated on the horizontal axis. All of the data groups are expressed in box plots. The illustrations in the panel indicate the following: (a), 90th percentile value; (b), 75th percentile value; (c), median value; (d), 25th percentile value; (e), 10th percentile value. The (dog ear height/design length) × 100% values are indicated on the vertical line. The gingko flap and simple suture groups are indicated on the bottom. The results were analyzed using the Mann-Whitney U test. The combinations used for the comparison are indicated by horizontal bars in the panel. Asterisks indicate statistically significant differences (p < 0.05); the actual p values are shown.
