UT Southwestern plastic surgeons deploy new carbon dioxide-based fracti...( DALLAS Feb. 13 2008 UT Southwester...),Health

DALLAS Feb. 13, 2008 UT Southwestern Medical Center plastic surgeons are among a handful in the nation deploying a new type of laser that goes deeper into the skin to help reduce wrinkles, tighten surface structures and treat pigmentation differences.

UT Southwestern was one of only two U.S. centers to receive the Food and Drug Administration-approved laser for initial testing before making it available for patients. Plastic surgeons at UT Southwestern have completed testing and are now starting to use the new carbon dioxide-based fractional laser, which combines minute focused columns of laser-induced injury with heat deposition for less skin damage and quicker recovery time.

Fractional lasers are like aerating your lawn, where you have a bunch of holes in your lawn, but you have normal lawn in between. This allows for more rapid healing because intact, normal skin bridges the gap between the laser-induced injured skin, said Dr. Jeffrey Kenkel, vice chairman of plastic surgery whose research involves the effects of lasers on tissue. We can vary the distance between the holes, which has an effect on how much tissue we choose to treat. The treatment parameters are determined by what we are trying to accomplish for each of our patients.

Dr. Kenkel, director of the Clinical Center for Cosmetic Laser Treatment and chief of plastic surgery at the Veterans Administration Medical Center at Dallas, said the technology potentially could be one of the last decades biggest advancements in the laser world.

Whats appealing about carbon dioxide lasers is that not only can you get surface and deeper skin changes, but you get heat thats deposited into the skin resulting in improvement in wrinkles and skin tightening, said Dr. Kenkel.

There are lots of new lasers that come out on the market. We take a scientific approach when investigating new laser devices. We evaluate the laser on tissue that has either been removed from pati
