Plastic surgery

Plastic surgery is a medical specialty concerned with the "correction" or restoration of form and function. Though cosmetic or aesthetic surgery is the best-known kind of plastic surgery, most plastic surgery is not cosmetic; plastic surgery includes many types of reconstructive surgery, hand surgery, microsurgery, and the treatment of burns.

Etymology
In the term plastic surgery, the adjective plastic denotes sculpting or reshaping, derives from the Greek πλαστική (τέχνη), plastikē (tekhnē), “the art of modelling” of malleable flesh. The surgical definition of "plastic" first appeared in 1839. It predates the modern "synthetic product made from oil derivatives" sense of plastic, coined by Leo Baekeland in 1909, by seventy years.

History
Treatments for the plastic repair of a broken nose are first mentioned in the Edwin Smith Papyrus, a transcription of an Ancient Egyptian medical text, the oldest known surgical treatise, dated to the Old Kingdom from 3000 to 2500 BC. Reconstructive surgery techniques were being carried out in India by 800 BC. Sushruta was a physician that made important contributions to the field of plastic and cataract surgery in 6th century BC. The medical works of both Sushruta and Charak originally in Sanskrit were translated into the Arabic language during the Abbasid Caliphate in 750 AD. The Arabic translations made their way into Europe via intermediaries. In Italy the Branca family of Sicily and Gaspare Tagliacozzi (Bologna) became familiar with the techniques of Sushruta.

British physicians traveled to India to see rhinoplasties being performed by native methods. Reports on Indian rhinoplasty performed by a Kumhar vaidya were published in the Gentleman's Magazine by 1794. Joseph Constantine Carpue spent 20 years in India studying local plastic surgery methods. Carpue was able to perform the first major surgery in the Western world by 1815. Instruments described in the Sushruta Samhita were further modified in the Western world.

The Romans also performed plastic cosmetic surgery. The Romans were able to perform simple techniques, such as repairing damaged ears from around the 1st century BC. For religious reasons, they did not dissect either human beings or animals, thus their knowledge was based in its entirety on the texts of their Greek predecessors. Notwithstanding, Aulus Cornelius Celsus left some surprisingly accurate anatomical descriptions, some of which — for instance, his studies on the genitalia and the skeleton — are of special interest to plastic surgery.

In 1465, Sabuncu's book, description, and classification of hypospadias was more informative and up to date. Localization of urethral meatus was described in detail. Sabuncuoglu also detailed the description and classification of ambiguous genitalia. In mid-15th-century Europe, Heinrich von Pfolspeundt described a process "to make a new nose for one who lacks it entirely, and the dogs have devoured it" by removing skin from the back of the arm and suturing it in place. However, because of the dangers associated with surgery in any form, especially that involving the head or face, it was not until the 19th and 20th centuries that such surgery became common.

Up until the techniques of anesthesia became established, surgeries involving healthy tissues involved great pain. Infection from surgery was reduced by the introduction of sterile techniques and disinfectants. The invention and use of antibiotics, beginning with sulfonamide and penicillin, was another step in making elective surgery possible.

In 1793, François Chopart performed operative procedure on a lip using a flap from the neck. In 1814, Joseph Carpue successfully performed operative procedure on a British military officer who had lost his nose to the toxic effects of mercury treatments. In 1818, German surgeon Carl Ferdinand von Graefe published his major work entitled Rhinoplastik. Von Graefe modified the Italian method using a free skin graft from the arm instead of the original delayed pedicle flap.

The first American plastic surgeon was John Peter Mettauer, who, in 1827, performed the first cleft palate operation with instruments that he designed himself. In 1845, Johann Friedrich Dieffenbach wrote a comprehensive text on rhinoplasty, entitled Operative Chirurgie, and introduced the concept of reoperation to improve the cosmetic appearance of the reconstructed nose.

In 1891, American otorhinolaryngologist John Roe presented an example of his work, a young woman on whom he reduced a dorsal nasal hump for cosmetic indications. In 1892, Robert Weir experimented unsuccessfully with xenografts (duck sternum) in the reconstruction of sunken noses. In 1896, James Israel, a urological surgeon from Germany, and in 1889 George Monks of the United States each described the successful use of heterogeneous free-bone grafting to reconstruct saddle nose defects. In 1898, Jacques Joseph, the German orthopaedic-trained surgeon, published his first account of reduction rhinoplasty. In 1928, Jacques Joseph published Nasenplastik und Sonstige Gesichtsplastik.

Development of modern techniques
The father of modern plastic surgery is generally considered to have been Sir Harold Gillies. A New Zealand otolaryngologist working in London, he developed many of the techniques of modern facial surgery in caring for soldiers suffering from disfiguring facial injuries during the First World War.

During World War I he worked as a medical minder with the Royal Army Medical Corps. After working with the renowned French surgeon Hippolyte Morestin on skin graft, he persuaded the army's chief surgeon, Arbuthnot-Lane, to establish a facial injury ward at the Cambridge Military Hospital, Aldershot, later upgraded to a new hospital for facial repairs at Sidcup in 1917. There Gillies and his colleagues developed many techniques of plastic surgery; more than 11,000 operations were performed on over 5,000 men (mostly soldiers with facial injuries, usually from gunshot wounds). After the war, Gillies developed a private practice with Rainsford Mowlem, including many famous patients, and travelled extensively to promote his advanced techniques worldwide.

In 1930, Gillies' cousin, Archibald McIndoe, joined the practice and became committed to plastic surgery. When World War II broke out, plastic surgery provision was largely divided between the different services of the armed forces and Gillies and his team was split up. Gillies himself, was sent to Rooksdown House near Basingstoke, which became the principal army plastic surgery unit; Tommy Kilner (who had worked with Gillies during the First World War, and who now has a surgical instrument named after him, the kilner cheek retractor), went to Queen Mary's Hospital, Roehampton, and Mowlem to St Albans. McIndoe moved to the recently rebuilt Queen Victoria Hospital in East Grinstead, Sussex, and founded a Centre for Plastic and Jaw Surgery. There, he treated very deep burns and serious facial disfigurement like loss of eyelids.

McIndoe was a brilliant and quick surgeon. He not only developed new techniques for treating badly burned faces and hands but also recognised the importance of the rehabilitation of the casualties and particularly of social reintegration back into normal life. He disposed of the "convalescent uniforms" and let the patients use their service uniforms instead. With the help of two friends, Neville and Elaine Blond, he also convinced the locals to support the patients and invite them to their homes. McIndoe kept referring to them as "his boys" and the staff called him "The Boss" or "The Maestro".

His other important work included development of the walking-stalk skin graft, and the discovery that immersion in saline promoted healing as well as improving survival rates for victims with extensive burns - this was a serendipitous discovery drawn from observation of differential healing rates in pilots who had come down on land and in the sea. His radical, experimental treatments led to the formation of the Guinea Pig Club at Queen Victoria Hospital, Sussex. Patients at the hospital formed the Guinea Pig Club. Among the better known members of his "club" were Richard Hillary, Bill Foxley and Jimmy Edwards.

Techniques and procedures
In plastic surgery, the transfer of skin tissue (skin grafting) is a very common procedure. Skin grafts can be taken from the recipient or donors:
 * Autografts are taken from the recipient. If absent or deficient of natural tissue, alternatives can be cultured sheets of epithelial cells in vitro or synthetic compounds, such as integra, which consists of silicone and bovine tendon collagen with glycosaminoglycans.
 * Allografts are taken from a donor of the same species.
 * Xenografts are taken from a donor of a different species.

Usually, good results are expected from plastic surgery that emphasizes careful planning of incisions so that they fall in the line of natural skin folds or lines, appropriate choice of wound closure, use of best available suture materials, and early removal of exposed sutures so that the wound is held closed by buried sutures.

Reconstructive surgery


Reconstructive plastic surgery is performed to correct functional impairments caused by burns; traumatic injuries, such as facial bone fractures and breaks; congenital abnormalities, such as cleft palates or cleft lips; developmental abnormalities; infection and disease; and cancer or tumors. Reconstructive plastic surgery is usually performed to improve function, but it may be done to approximate a normal appearance.

The most common reconstructive procedures are tumor removal, laceration repair, scar repair, hand surgery, and breast reduction plasty. According to the American Society of Plastic Surgeons, the number of reconstructive breast reductions for women increased in 2007 by 2 percent from the year before. Breast reduction in men also increased in 2007 by 7 percent. In 2012, there were 68,416 performed.

Some other common reconstructive surgical procedures include breast reconstruction after a mastectomy for the treatment of cancer, cleft lip and palate surgery, contracture surgery for burn survivors, and creating a new outer ear when one is congenitally absent.

Plastic surgeons use microsurgery to transfer tissue for coverage of a defect when no local tissue is available. Free flaps of skin, muscle, bone, fat, or a combination may be removed from the body, moved to another site on the body, and reconnected to a blood supply by suturing arteries and veins as small as 1 to 2 millimeters in diameter.

Cosmetic surgery
Cosmetic surgery is an optional procedure that is performed on normal parts of the body with the only purpose of improving a person’s appearance and/or removing signs of aging. In 2006, nearly 11 million cosmetic procedures were performed in the United States alone. The number of cosmetic procedures performed in the United States has increased over 50 percent since the start of the century. Nearly 12 million cosmetic procedures were performed in 2007, with the five most common surgeries being breast augmentation, liposuction, nasal surgery, eyelid surgery and abdominoplasty. The American Society for Aesthetic Plastic Surgery looks at the statistics for thirty-four different cosmetic procedures. Nineteen of the procedures are surgical, such as rhinoplasty or facelift. The nonsurgical procedures include Botox and laser hair removal. In 2010, their survey revealed that there were 9,336,814 total procedures in the United States. Of those, 1,622,290 procedures were surgical (p. 5). They also found that a large majority, 81%, of the procedures were done on Caucasian people (p. 12). The increased use of cosmetic procedures crosses racial and ethnic lines in the U.S., with increases seen among African-Americans, Asian Americans and Hispanic Americans as well as Caucasian Americans. In Europe, the second largest market for cosmetic procedures, cosmetic surgery is a $2.2 billion business. Cosmetic surgery is now very common in countries such as the United Kingdom, France, and Germany. In Asia, cosmetic surgery has become an accepted practice, and countries such as China and India has become Asia's biggest cosmetic surgery markets. Thailand is also one of the main cosmetic surgery markets in Asia, in particular for affordable breast augmentation and sex reassignment surgery, with international patients coming from Australia, Europe and neighboring Asian countries.

The most prevalent aesthetic/cosmetic procedures include:
 * Abdominoplasty ("tummy tuck"): reshaping and firming of the abdomen
 * Blepharoplasty ("eyelid surgery"): reshaping of the eyelids or the application of permanent eyeliner, including Asian blepharoplasty
 * Phalloplasty ("penile liposuction") : construction (or reconstruction) of a penis or, sometimes, artificial modification of the penis by surgery, often for cosmetic purposes
 * Mammoplasty:
 * Breast augmentations ("breast implant" or "boob job"): augmentation of the breasts by means of fat grafting, saline, or silicone gel prosthetics, which was initially performed to women with micromastia
 * Reduction mammoplasty ("breast reduction"): removal of skin and glandular tissue, which is done to reduce back and shoulder pain in women with gigantomastia and/or for psychological benefit men with gynecomastia
 * Mastopexy ("breast lift"): Lifting or reshaping of breasts to make them less saggy, often after weight loss (after a pregnancy, for example). It involves removal of breast skin as opposed to glandular tissue
 * Buttock augmentation ("butt implant"): enhancement of the buttocks using silicone implants or fat grafting ("Brazilian butt lift") and transfer from other areas of the body
 * Buttock lift: lifting, and tightening of the buttocks by excision of redundant skin
 * Chemical peel: minimizing the appearance of acne, chicken pox, and other scars as well as wrinkles (depending on concentration and type of agent used, except for deep furrows), solar lentigines (age spots, freckles), and photodamage in general. Chemical peels commonly involve carbolic acid (Phenol), trichloroacetic acid (TCA), glycolic acid (AHA), or salicylic acid (BHA) as the active agent.
 * Cryolipolysis: refers to a medical device used to destroy fat cells. Its principle relies on controlled cooling for non-invasive local reduction of fat deposits to reshape body contours. In September 2010, the Food and Drug Administration approved the non surgical Zeltiq device for the purpose of selective fat reduction for “cryolipolysis”.
 * Labiaplasty: surgical reduction and reshaping of the labia
 * Lip enhancement: surgical improvement of lips' fullness through enlargement
 * Rhinoplasty ("nose job"): reshaping of the nose
 * Otoplasty ("ear surgery"/"ear pinning"): reshaping of the ear, most often done by pinning the protruding ear closer to the head.
 * Rhytidectomy ("face lift"): removal of wrinkles and signs of aging from the face
 * Neck lift: tightening of lax tissues in the neck. This procedure is often combined with a facelift for lower face rejuvenation.
 * Browplasty ("brow lift" or "forehead lift"): elevates eyebrows, smooths forehead skin
 * Midface lift ("cheek lift"): tightening of the cheeks
 * Genioplasty ("chin implant"): augmentation of the chin with an implant, usually silicone, by sliding genioplasty of the jawbone or by suture of the soft tissue
 * Cheek augmentation ("cheek implant"): implants to the cheek
 * Orthognathic Surgery: manipulation of the facial bones through controlled fracturing
 * Fillers injections: collagen, fat, and other tissue filler injections, such as hyaluronic acid
 * Brachioplasty ("Arm lift"): reducing excess skin and fat between the underarm and the elbow
 * Laser Skin Rejuvenation or Resurfacing:The lessening of depth in pores of the face
 * Liposuction ("suction lipectomy"): removal of fat deposits by traditional suction technique or ultrasonic energy to aid fat removal
 * Keloid removal - The keloid forms when the body fails to stop producing new tissue during healing. This leads to an overabundance of fibrous protein and collagen.

Sub-specialties
Plastic surgery is a broad field, and may be subdivided further. In the United States, plastic surgeons are board certified by American Board of Plastic Surgery and the American Osteopathic Board of Surgery. Subdisciplines of plastic surgery may include:

Burn surgery generally takes place in two phases. Acute burn surgery is the treatment immediately after a burn. Reconstructive burn surgery takes place after the burn wounds have healed.
 * Burn

Aesthetic surgery is an essential component of plastic surgery. Plastic surgeons use cosmetic surgical principles in all reconstructive surgical procedures as well as isolated operations to improve overall appearance.
 * Cosmetic

Craniofacial surgery is divided into pediatric and adult craniofacial surgery. Pediatric craniofacial surgery mostly revolves around the treatment of congenital anomalies of the craniofacial skeleton and soft tissues, such as cleft lip and palate, craniosynostosis, and pediatric fractures. Adult craniofacial surgery deals mostly with fractures and secondary surgeries (such as orbital reconstruction) along with orthognathic surgery. Craniofacial surgery is an important part of all plastic surgery training programs, further training and subspecialisation is obtained via a craniofacial fellowship.
 * Craniofacial

Hand surgery is concerned with acute injuries and chronic diseases of the hand and wrist, correction of congenital malformations of the upper extremities, and peripheral nerve problems (such as brachial plexus injuries or carpal tunnel syndrome). Hand surgery is an important part of training in plastic surgery, as well as microsurgery, which is necessary to replant an amputated extremity. The Hand surgery field is also practiced by orthopedic surgeons and general surgeons (see Hand surgeon). Scar tissue formation after surgery can be problematic on the delicate hand, causing loss of dexterity and digit function if severe enough.
 * Hand

Microsurgery is generally concerned with the reconstruction of missing tissues by transferring a piece of tissue to the reconstruction site and reconnecting blood vessels. Popular subspecialty areas are breast reconstruction, head and neck reconstruction, hand surgery/replantation, and brachial plexus surgery.
 * Micro

Children often face medical issues very different from the experiences of an adult patient. Many birth defects or syndromes present at birth are best treated in childhood, and pediatric plastic surgeons specialize in treating these conditions in children. Conditions commonly treated by pediatric plastic surgeons include craniofacial anomalies, cleft lip and palate and congenital hand deformities.
 * Pediatric

Plastic surgery obsession
Though media and advertising do play a large role in influencing many people's lives, researchers believe that plastic surgery obsession is linked to psychological disorders. Body dysmorphic disorder is seen as playing a large role in the lives of those who are obsessed with plastic surgery in order to correct a perceived defect in their appearance.

BDD is a disorder resulting in the sufferer becoming “preoccupied with what they regard as defects in their bodies or faces.” While 2% of people suffer from body dysmorphic disorder in the United States, 15% of patients seeing a dermatologist and cosmetic surgeons have the disorder. Half of the patients with the disorder who have cosmetic surgery performed are not pleased with the aesthetic outcome. BDD can lead to suicide in some of its sufferers. While many with BDD seek cosmetic surgery, the procedures do not treat BDD, and can ultimately worsen the problem. The psychological root of the problem is usually unidentified; therefore causing the treatment to be even more difficult. Some say that the fixation or obsession with correction of the area could be a sub-disorder such as anorexia or muscle dysmorphia.

In some cases, people whose physicians refuse to perform any further surgeries, have turned to "do it yourself" plastic surgery, injecting themselves and running extreme safety risks.
