What Is Necrosectomy?

The autopsy method is to standardize the autopsy according to the order of operations in the forensic autopsy. The conventional anatomy methods are divided into straight-line method, T-shaped arc method, Y-shaped method and inverted Y-shaped method. Straight cut method: Start from the midline of the lower edge of the mandible, and cut the skin and subcutaneous tissue along the neck, chest, and abdominal midline around the left side of the umbilicus to the upper edge of the pubic bone. If necessary, it can be extended to one or both sides of the groin. This method is generally used. T-shaped arc cutting method: first make a transverse incision from the left shoulder peak through the sternum to the right shoulder peak, and then make a straight incision downward at the midpoint of the arc, around the left side of the umbilicus to the upper edge of the pubic symphysis. The advantage of this technique is to keep the neck shape intact. Y-shaped incision: cut from the left and right ear mastoids vertically to the upper edge of the clavicle, and then cut inward to the sternal notch to meet. This method should be used when the neck is damaged (such as cable grooves, scoring and wounds). Inverted Y-shaped incision: first cut the neck and chest skin to the upper abdomen in a straight line method, then make a semi-circular incision in the abdomen, and flip the flap downward. This operation can be used when the abdominal wall is damaged. ^[1]
