Scarring During Cosmetic Surgery Can Get Reduced with New Device

Scientists at Binghamton University have come up with a new device that could help to reduce scarring during cosmetic surgery. The device can help in determining the alignment of skin tension lines, which is crucial for the healing of the wound post-operation.
Human skin is an intricate tissue that displays properties that appear primarily from the alignment of collagen fibres in the skin’s dermis layer, eventually causing skin tension lines.

These lines are crucial for surgery, as they are used to direct incisions that create the least visible scars, according to the study which has been published in the journal Acta Biomaterialia.

There are many skin tension guidelines that would assist surgeons to make slash that creates unnoticeable scars, according to researchers from Binghamton University in the US.
However, skin anisotropy, or the skin’s property of having operatively dependent mechanical properties, is presumed to alter from subject to subject, with no single guideline universally recognized as the best to carry out for surgical applications.
Skin can be easily stretched in one direction than another. It has been found that these lines have significant overtone, according to Guy German, an associate professor at Binghamton University.

Surgeons, especially cosmetic surgeons, use these lines to determine which direction to make cuts in order to make the least-noticeable blemish.
If cuts are made across the direction that collagen is set, the possibility of keloid scar formation, or elevated scars that can grow bigger than the original injury, is expanded.

The new device is more precise than other existing devices and the manual tests that surgeons carry out.
The device is also more effective, as it makes use of a single test that lasts for a few seconds to count skin tension orientation. Even though there are many other devices that carry out these tasks; however, they need more than one measurement to set up the direction. The devices that make use of a single test can presently only measure the skin tension direction to an accuracy of 45 degrees.
