A new device to minimize postoperative scarring

Surgery is always associated with scars. However, today there are many options to minimize scarring after surgery.

Researchers at Binghamton University, State University of New York, have developed a new device that can help minimize scarring during surgery.

The device can determine the orientation of Langer lines (skin tension lines) which is important for wound healing after surgery.

Langer's lines: an important landmark for plastic surgeons

Human skin is a complex tissue that has certain mechanical properties, mainly due to the location of collagen fibers in the dermis. They are the reason for the presence of skin tension lines.

Langer's lines are vital to surgery as they are used to guide incisions that produce the least visible scarring.

While there are many guidelines for defining skin tension lines that help surgeons make incisions that create invisible scars, skin anisotropy (the property of the skin to have mechanically oriented properties) can vary from patient to patientv.

Is it safe to use skin tension line maps

Skin is easier to stretch in one direction than the other, this has been known for a long time. For surgeons, especially plastic surgeons, this property of the skin is of particular value.

The fact is that when an incision is made along the line of skin tension, healing occurs, firstly, faster, and secondly, the formation of a scar is accompanied by a minimal proliferation of connective tissue.

This makes the post-surgery scar as aesthetically pleasing as possible, and becomes almost invisible over time.

If an incision is made across collagen fibers and skin tension lines, there is an increased risk of keloid and hypertrophic scarring.

Surgeons currently use either

skin tension line maps or manual manipulations to determine the local orientation of skin tension.

Manual manipulations are often inaccurate, and studies show that the direction of skin tension lines varies from person to person.

New Langer line detection device

A new device created by US scientists is more accurate than skin tension line maps and manual tests performed by surgeons.

The device also saves time, as only one test is used to

skin tension orientation which lasts a few seconds.

Scientists hope that the new device will someday become part of the usual equipment in operating rooms.

Surgeons will use it to quickly and accurately determine the direction of the skin tension line and plan their incisions to

minimize scarring.
