Question

Langer Lines or cleavage lines of the skin are lines that correspond to the orientation of collagen lines fibers in the dermis of the skin.

Why would it be important to use these lines during surgery? Especially plastic surgery? What might be some complications if these lines aren't used during surgery?

Answer 1

Langer's lines or cleavage lines are topological lines drawn on a map of the human body. They correspond to the natural orientation of collagen fibers in the dermis, and are generally parallel to the orientation of the underlying muscle fibers. Langer's lines have relevance to forensic science and the development of surgical techniques.

  Knowing the direction of Langer's lines within a specific area of the skin is important for surgical operations, particularly cosmetic surgery.

  Incisions made parallel to Langer's lines may heal better and produce less scarring than those that cut across. Conversely, incisions perpendicular to Langer's lines have a tendency to pucker and remain obvious, although sometimes this is unavoidable.
