PLASTIC SURGERY (continued from page 27) struction of the radical pelvic cancer surgery defects with flaps transferred into the pelvis. This procedure was originated by UofL Plastic Surgery, which maintains international recognition as a center for these reconstructions. Another set of pioneering cancer reconstructions coming from UofL Plastic Surgery is reconstruction of head and neck cancer resections by microvascular flap transfers, in which Louisville again remains a center. CONGENITAL DEFECT AND CRANIOFACIAL RECON- STRUCTION Among the most common birth defects are clefts of the lip and palate. Procedures developed in past centuries attempted to ad- dress these problems, but with limited success. A significant step forward occurred in the 1950s when plastic surgeon Ralph Millard, MD, of Miami devised a cleft lip repair which gave a significantly more normal appearance. Severe congenital deformities such as misshapen faces and skulls remained vexing unresolved problems until plastic surgeon Paul Tessier, MD, of Paris made major break- throughs in the 1960s. He almost singlehandedly created the field of craniofacial surgery. BURN CARE AND RECONSTRUCTION Thermal burns represent a substantial source of mortality, principally secondary to high vulnerability to infection in the devitalized skin of full thickness (third degree) burns. A significant step forward occurred in the 1960s, with recognition of the value of excising the dead tissue shortly after the injury and before infection could set in, a process called “early excision.” An effective component of this strategy was layered removal of the burned tissue with skin graft knives that could shave burned tissue in thin layers until a precise interface with living tissue was defined, followed by prompt skin grafting. This technique was developed in 1970 by Yugoslavian plastic surgeon Zona Janzekovic, MD. In the late 1970s, UofL plastic surgeons at the burn care unit of Norton Children’s Hospital became among the first American users and proponents of this technique, with demonstrably superior mortality and functional outcomes. It has now become a mainstay of therapy internationally and is skillfully practiced at the UofL Hospital Burn Unit, where plastic surgeons and general surgeons collaborate to bring excellence in burn care to Kentucky and beyond. Plastic surgeons associated with burn units also encounter substantial challenges in addressing the scar deformities and contractures affecting limb joints and facial features. HAND SURGERY Hand surgery draws practitioners from plastic surgery, orthopedic surgery and general surgery. Major improvements in hand injury care came out of World War II. Subsequently, Louisville surgeons Harold Kleinert, MD, and Joseph Kutz, MD, made a significant breakthrough in flexor tendon repair that captured international acclaim. Another breakthrough occurred with the development of 28 LOUISVILLE MEDICINE microvascular techniques that allowed small upper extremity vessel repairs and replantation of traumatic amputations. Louisville became a leader in this arena, with Kleinert, Kutz and Associates creating a major replantation center at Jewish Hospital, and with pioneering instruments and training techniques that were developed by Dr. Robert Acland in the Plastic Surgery Laboratory at UofL. These activities provided key infrastructure for achieving hand and face transplantations. As described elsewhere in this volume, the world’s first long-term success in transplantation of skin-bearing structures, a hand transplant, occurred here twenty years ago. This established a field called “Vascular Composite Allotransplantation” that has be- come one of the most exciting activities in contemporary medicine. RECONSTRUCTION OF TRAUMA Reconstruction of traumatic injuries is a mainstay of plastic sur- gery. In addition to replantation of severed limbs, repair of facial fractures is a major activity, with significant numbers coming from motor vehicle accidents. This field draws practitioners from plastic surgery, oral and maxillofacial surgery, and otolaryngology. These specialties often work together in teams where the most severe injuries are brought, such as the UofL Hospital Level One Trauma Center. A major advance in this field was development of rigid internal fixation devices, which are small strong frames attached to fractured bones with screws to solidly immobilize healing fractures of the craniofacial skeleton, hands and feet. BODY CONTOURING Contemporary nutrition habits have generated more people with a greater body mass index than in previous eras. This situation gave rise to bariatric surgery and non-surgical programs that produce massive weight loss. However, afterwards, patients are usually left with substantial amounts of excess skin. Body contouring surgery has been developed to address this, with large excisions of excess skin in affected body areas. Along with body contouring, chal- lenging hernias and defects of the abdominal wall must often be addressed. These create major technical challenges for involved plastic and general surgeons, and their repair is a substantial focus of current activity. FRONTIER OF PLASTIC SURGERY Today, there are many promising frontiers for plastic surgery. These include the transplantation of hands, faces and other body parts. Also, intensive laboratory investigation is developing tissue engi- neering of organs and body parts. Although just entering clinical application, this will likely become the next exciting frontier of plastic surgery. As long as human needs call, the field of plastic surgery will surely respond with creative ingenuity and dedicated commitment.
