PLASTIC SURGERY PATIENTS BENEFIT GREATLY FROM an Era of Enormous Progress in Plastic Surgery Gordon Tobin, MD P lastic surgery has experienced spectacular progress over the past half-century, with greatly increased benefits to the patients served. American plastic surgeons have led the world in this effort, and Louisville has contributed substantially to the progress. During this time, the field has generated many areas of focused skills, with involved practitioners developing sub- specialty expertise. This report will summarize the broad progress of the recent era, as well as significant developments in specialty areas. The term “plastic surgery” is derived from Ancient Greek de- scribing the creation and molding of form. Broadly, the specialty combines aesthetic skills focused on improvement of appearance, reconstructive skills focused on restoring lost function, and applied wound healing science. In practice, these three elements are assem- bled as needed in customized surgical plans to address individual patient needs. Thus, plastic surgery is a blend of art and science that requires creativity and a broad set of skills that can be drawn upon in unique combinations to create optimal outcomes. An interesting feature of modern plastic surgery is incorporation of the newest biologic technology alongside some of the oldest known surgical procedures. Examples of new technologies include transplantation of hands, faces and other structures; a field that was pioneered in Louisville. Examples of ancient surgical procedures still used are current nasal reconstruction techniques, which closely resemble those developed in India over 2,500 years ago. Vascularized tissue transfers called “flaps” originated in Europe in the Middle Ages, but these have become much more effective by modern discover- ies of vascular anatomy and microvascular vessel suturing; again, techniques pioneered in Louisville. AESTHETIC SURGERY The public image of plastic surgery is largely that of aesthetic surgery, the crafting of enhanced appearance and beauty. The origins of this field come from early 20 th century efforts to surgically sculpt and improve features, such as in aesthetic rhinoplasty, or to modify skin relaxation and sagging associated with aging by selective excisions and tissue repositioning, such as in the classic face-lift procedure. In recent years, these procedures have been refined and joined by new technology such as tissue fillers and skin resurfacing/rejuve- nating agents. In addition to facial surgery, a substantial component of aesthetic surgery is focused on aesthetic remodeling of breasts. Reductions of excess size combine reconstructive and aesthetic goals. Augmentations use prostheses developed in the US from advances in the silicone industry in the 1960s. Another significant aesthetic area is liposuction for selective subcutaneous fat reduction, which was pioneered in France in the 1970s. Coming from the liposuction procedure have been techniques for reintroduction of aspirated fat as subcutaneous grafts to enhance form in a variety of sites. Now, biochemical products of modified fat aspirates are showing great promise in emerging new therapies. Studies at the University of Louisville (UofL) Cardiovascular Innovation Institute place UofL in the forefront of this area. CANCER RECONSTRUCTION A major plastic surgery technique is tissue transfer via vascularized flap of skin, muscle and other tissues. These techniques, many introduced at UofL, have become a pillar of reconstruction for cancer resection defects in all areas of the body. A common current application is breast reconstruction after mastectomy using large skin-muscle flaps that were pioneered in the 1970s. Additional breakthroughs derived from these flap transfers have been recon- (continued on page 28) JANUARY 2019 27
