Plastic surgeons countdown first full facial transplantation

02.03.2006


First studies reveal next steps in historic procedure



Even after news of the first partial facial transplantation performed in France spread around the world, plastic surgeons have continued to research how to make the first full facial transplantation a reality. In the first peer-reviewed, scientific studies of their kind, U.S. plastic surgeons demonstrated how to successfully complete a full facial tissue transplantation from one human body to another, reports the March issue of Plastic and Reconstructive Surgery® (PRS), the official medical journal of the American Society of Plastic Surgeons (ASPS).

"For the first time, we have scientific data that takes us beyond traditional reconstructive techniques and partial facial transplantation," said ASPS President Bruce Cunningham, MD. "What we thought of as a possibility – reconstructing the entire face of someone with a severe facial disfigurement, in one surgery, from one complete facial skin flap taken from a donor – is no longer just theory, but will become an actuality."


"Through these particular studies we have determined that full facial tissue transplantation is a successful approach in helping patients horribly disfigured by burns, accidents and other trauma," said study lead author Maria Siemionow, MD, director of plastic surgery research at the Cleveland Clinic. "The transplantation of a facial tissue flap from one cadaver to another has allowed us to do the following: estimate the time it takes to perform this particular transplantation, perfect our technique and visually confirm that a facial tissue flap is a match when covering severe burns and other trauma."

Although traditional methods for facial reconstruction, which include skin grafts and flaps, are reliable and effective techniques for reconstructing the face, they may not be ideal, according to the studies. It is nearly impossible to match the skin quality, texture and color of the face with any other tissue available on the body. In addition, it takes multiple grafts and surgeries to successfully reconstruct the entire face. Many patients are left with a patchy, unfavorable appearance, including large scars and mismatched skin. The studies found the only way to surgically match facial skin texture, pliability and color is through facial transplantation.

"There is no doubt that facial transplantation can improve the quality of life for patients, however, facial transplantation will not replace traditional techniques," said Rod Rohrich, MD, editor of PRS. "This is an exciting time in plastic surgery, but it is important to remember that, at least in the near future, facial transplantation will be a last resort procedure performed on carefully selected patients on a case-by-case basis."

In the studies, doctors used cadavers to perform mock facial transplantations in order to outline the necessary steps to transplant a human face. Through these trials, they were able to visually show the full extent of the procedure’s outcome.

During the procedure it took surgeons approximately five hours to perform the mock facial transplantation, this did not include vessel and nerve repair. In living recipients, the authors estimate the total length of surgery will be approximately 11-15 hours.

"Plastic surgeons have historically been at the forefront of transplantation medicine," said Dr. Cunningham. "The first successful hand transplantation was performed by a plastic surgeon in 1998, as was the first kidney transplant in 1954. The idea of tissue transplantation has opened a new era in this field of medicine."

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
