The tightness of the flap during suture is actually determined by the incision. Many doctors use the flaps on both sides of the tumor to judge the resection width before operation, but the resection amount is too large and the tension of the flaps is too high. First, just pinch the middle, thinking that the middle is enough, and there will be no problem. In fact, if the middle is enough, it is to use the expansion potential of the skin on both sides. When the skin on both sides needs to expand the suture, it is not enough to support the middle. Second, it is not enough to have only two fingers folded. The thickness of the intermediate tissue should be reduced. It takes more skin to cling to the chest wall than to cover it. Third, the stitching itself also needs to use some widths. Fourthly, unlike the feeling, the skin potential of thin people is smaller than that of fat people, which may be related to less tissue removed by the flap and more layers retained. Fifth, because the radians on both sides of the spindle-shaped incision are asymmetric, two points that are pinched exactly the same may not be sewn together.
How can it be more accurate? You can try this method.
After drawing the incision, add a middle line at both ends of the incision, nipple and lump, and extend to both ends. Press your fingers on one side of the incision line and push inward. If the incision line can be pushed through the center line as a whole, it is considered qualified. If the incision cannot continue inward due to tumor, the incision radian can be adjusted appropriately, and then the lower part of the outer incision line is pushed inward, and the upper part of the inner incision line is pushed outward, or crossed at the same time. Minimally invasive small incision is not recommended.
