Langer’s lines, Langer lines of skin tension, or sometimes called cleavage lines, are topological lines drawn on a map of the human body. They are parallel to the natural orientation of collagen fibers in the dermis, as well as the underlying muscle fibers.
What are the cleavage lines in the skin?
Wound Closure Skin tension lines, also known as Langer’s lines or lines of cleavage, are linear clefts in the skin that indicate the direction of orientation of the underlying collagen fibers. If the skin is disrupted parallel to the long axis of the fibers, the wound tends to reapproximate.
Why are lines of cleavage clinically significant?
They partition the skin and indicate the predominant direction of underlying collagen fibers in the reticular layer of the dermis. These are clinically and surgically significant because any procedure resulting in a cut at right angles to a cleavage line is usually pulled open due to the recoil from cut elastic fibers.
