The study was conducted to survey the distribution of perforators in the ALT region in segments 1/3,1/10,1/8 and 1/16 and survey the distribution of perforators in circuit through the ALT region in the center baseline. The results show that when divided into 10 segments, the perforators focused on the rapid spread from segment 2/10 to segment 7/10 with the total rate is 83.0 percent. When divided into eight segments, the perforators focused on 72.6 percent from segment 2/8 to segment 6/8. When dividing baseline into 16 equal segments standard, the perforators focused on the rapid spread from segment 3 to 5/16, and segment 10 - 12/16 with the corresponding rate was 33.8 percent and 26.2 percent. The number of muscular perforators are dominated in the circle with diameter from 3 to 6 cm, with 1/3 of the perforators are found in a circle diameter of 6 cm. In conclusion, the baseline is divided into 16 segments and determine 5cm diameter circle convenient for the surgeon to design ALT flap clinically.
