From the perspective of modern aesthetics, most of them adopt the way of left-right crosscutting. In recent years, foreign countries advocate longitudinal incision, that is, vertical incision In China, vertical incision is also the main method, and now 98% of abdominal operations use vertical incision. It has the following advantages: 1 is most in line with human anatomical structure, and the abdominal wall muscle is composed of rectus abdominis, external oblique muscle and internal oblique muscle. Crosscutting is to cut off the muscles above. After the muscle heals, it will be permanently replaced by scar tissue. Without elasticity, toughness and tensile strength, can people be strong? There are few complications. Abdominal hernia is caused by abdominal muscle weakness or surgical destruction of abdominal muscle. The abdominal wall muscle fibers are vertical, which hardly damages the muscles in the vertical direction. You only need to open a vertical seam to enter the abdominal cavity during the operation. It is not advisable to affect health for the sake of beauty.
