PLASTIC SURGERY INNOVATION DEFINES Plastic Surgery Jerry O’Daniel, MD P lastic surgery is a specialty unique amongst all the surgical specialties. Plastic surgeons do not treat one specific area of the body. They incorporate basic principles that apply across all specialties. Innovation has been at the heart of plastic surgery since the origins of the specialty. This history includes innovative procedures and products, such as microvascular surgery, liposuction and tissue expansion. 1 Innovations in plastic surgery are not limited to academic centers; all plastic surgeons are willing and ready to seek creative solutions to improve current practice and to solve difficult clinical problems. 2 In the 50 top-cited plastic surgery articles, almost half introduced a new or modified surgical technique that considerably changed clinical practice. 3 Innovation is defined as “an introduction of something new, including a new idea, method or device.” 4 It is an improvement to something that already exists. It is much more than just new techniques and technology; a new idea, a new perspective, or even a new question can be as valuable as a new device. 5 Innovation must not be confused with invention, which is defined as a “discovery or finding” that is developed after study and experimentation. 6 An innovation requires implementation in a way that captures its value (usefulness and profitability). 7 Examples of innovation include the use of new devices in existing procedures, the introduction of new procedures that use new devices, and using existing devices in new procedures. 8 For example, the invention of the microscope propelled innovation in the field of microsurgery, which ultimately led to replantation surgery and free tissue transfer. Most of the technology in plastic surgery is not rooted in plastic surgery but is adapted technology from larger market specialties such as cardiology and orthopedic surgery. Plate-and-screw fixation, designed initially for orthopedic surgery, was miniaturized and adopted for craniofacial rigid fixation. Hyaluronic acid, marketed as Synvisc (Genzyme Corp., Cambridge, Mass.) was developed for joint injections. Botulinum toxin type A (Botox; Allergan, Inc., Irvine, Calif.) was initially developed for the ophthalmology market to treat blepharospasm. Finally, liposuction consisted of technology adapted from gynecologists’ dilation and curettage cannulas. It is certainly common for technology that is developed in one sector to be adapted into other sectors, and certainly speaks to the keen eye and creativity of plastic surgeons. Thirty-five years ago, as a general surgery intern, I was exposed to two plastic surgical innovators whose individual contributions created the field of microsurgery and craniofacial surgery. These chance opportunities set the direction of a most rewarding carrier as a plastic surgeon. On the first occasion, I had the opportunity to witness Dr. Robert Acland perform a microvascular jejunal free tissue transfer to reconstruct the pharynx and upper esophagus to restore oral lining and deglutition on a patient who had just undergone an extirpation of an advanced head and neck cancer. Dr. Acland was a pioneer who utilized the invention of the operating microscope to propel innovation in the field of microsurgery, which ultimately led to free tissue transfer. By taking the invention of the operating microscope, Dr. Acland was able to help innovate a new surgical specialty, and many of his original basic principles and instrument designs are utilized today. This innovation has been widely adopted by other surgical specialties including otolaryngology (head and neck surgery) and orthopedic surgery and today microsurgical free tissue transfer is routinely performed by thousands of surgeons around the world to save lives and restore form and function to millions of patients since. In the same year, Dr. Paul Tessier was in Louisville to work with Dr. Gerald Verdi to perform surgical correction of very rare and complex craniofacial deformities of pediatric patients who had no existing treatment options. Dr. Tessier was a French plastic surgeon who pioneered the entire field of craniomaxillofacial surgery and at that time was only one of a few doctors in the world capable of successful correction of craniofacial deformities that resulted from abnormal growth of the craniofacial skeleton. These deformities affected the normal appearance of the face and skull and created life- threatening increased intracranial pressure and airway obstruction. This visit by Dr. Tessier was transformative as I was allowed to (continued on page 20) JANUARY 2019 19
