A dermatome is a surgical instrument for producing thin slices of skin from a donor area, for use in skin grafts. One of its main applications is for reconstituting skin areas damaged by third degree burns or trauma.
Dermatomes can be operated either manually or electrically. The first drum dermatomes, developed in the 1930s, were manually operated. Afterwards, dermatomes which were operated by air pressure, such as the Brown dermatome, achieved higher speed and precision. Electrical dermatomes are better for cutting out thinner and longer strips of skin with a more homogeneous thickness.
Those are manual dermatomes and the term knife or scalpel is used to describe them. Their disadvantages are harvesting of grafts with irregular edges and grafts of variable thickness. Their operator has to be experienced in their use for optimal results. [1]
There are several types of dermatomes, usually named after their inventor.
Plastic surgery is a surgical specialty involving the restoration, reconstruction or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery. Reconstructive surgery includes craniofacial surgery, hand surgery, microsurgery, and the treatment of burns. While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic surgery aims at improving the appearance of it.
Surgery is a medical specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas.
A scalpel, lancet, or bistoury is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various arts and crafts. Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable single-use blades. Disposable scalpels usually have a plastic handle with an extensible blade and are used once, then the entire instrument is discarded. Scalpel blades are usually individually packed in sterile pouches but are also offered non-sterile. Double-edged scalpels are referred to as "lancets".
Rhinoplasty, commonly called nose job, medically called nasal reconstruction is a plastic surgery procedure for altering and reconstructing the nose. There are two types of plastic surgery used – reconstructive surgery that restores the form and functions of the nose and cosmetic surgery that changes the appearance of the nose. Reconstructive surgery seeks to resolve nasal injuries caused by various traumas including blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery can also treat birth defects, breathing problems, and failed primary rhinoplasties. Rhinoplasty may remove a bump, narrow nostril width, change the angle between the nose and the mouth, or address injuries, birth defects, or other problems that affect breathing, such as a deviated nasal septum or a sinus condition. Surgery only on the septum is called a septoplasty.
Tissue expansion is a technique used by plastic, maxillofacial and reconstructive surgeons to cause the body to grow additional skin, bone, or other tissues. Other biological phenomena such as tissue inflammation can also be considered expansion.
Breast augmentation and augmentation mammoplasty is a cosmetic surgery technique using breast-implants and fat-graft mammoplasty techniques to increase the size, change the shape, and alter the texture of the breasts. Augmentation mammoplasty is applied to correct congenital defects of the breasts and the chest wall. As an elective cosmetic surgery, primary augmentation changes the aesthetics – of size, shape, and texture – of healthy breasts.
Skin grafting, a type of graft surgery, involves the transplantation of skin. The transplanted tissue is called a skin graft.
Grafting refers to a surgical procedure to move tissue from one site to another on the body, or from another creature, without bringing its own blood supply with it. Instead, a new blood supply grows in after it is placed. A similar technique where tissue is transferred with the blood supply intact is called a flap. In some instances, a graft can be an artificially manufactured device. Examples of this are a tube to carry blood flow across a defect or from an artery to a vein for use in hemodialysis.
Vaginoplasty is any surgical procedure that results in the construction or reconstruction of the vagina. It is a type of genitoplasty. Pelvic organ prolapse is often treated with one or more surgeries to repair the vagina. Sometimes a vaginoplasty is needed following the treatment or removal of malignant growths or abscesses in order to restore a normal vaginal structure and function. Surgery to the vagina is done to correct congenital defects to the vagina, urethra and rectum. It will correct protrusion of the urinary bladder into the vagina (cystocele) and protrusion of the rectum (rectocele) into the vagina. Often, a vaginoplasty is performed to repair the vagina and its attached structures due to trauma or injury. Labiaplasty, which alters the appearance of the vulva, can be performed as a discrete surgery, or as a subordinate procedure within a vaginoplasty.
Otoplasty denotes the surgical and non-surgical procedures for correcting the deformities and defects of the pinna, and for reconstructing a defective, or deformed, or absent external ear, consequent to congenital conditions and trauma. The otoplastic surgeon corrects the defect or deformity by creating an external ear that is of natural proportions, contour, and appearance, usually achieved by the reshaping, the moving, and the augmenting of the cartilaginous support framework of the pinna. Moreover, the occurrence of congenital ear deformities occasionally overlaps with other medical conditions.
A surgical instrument is a tool or device for performing specific actions or carrying out desired effects during a surgery or operation, such as modifying biological tissue, or to provide access for viewing it. Over time, many different kinds of surgical instruments and tools have been invented. Some surgical instruments are designed for general use in all sorts of surgeries, while others are designed for only certain specialties or specific procedures.
Lip augmentation is a cosmetic procedure that modifies the shape of the lips using fillers, such as collagen or implants. The procedure may be performed to increase lip size, correct asymmetry, create protrusion, or adjust the ratio of the top and bottom lips. The procedure typically involves surgical injection, though temporary non-surgical alternatives exist.
Hair transplantation is a surgical technique that removes hair follicles from one part of the body, called the 'donor site', to a bald or balding part of the body known as the 'recipient site'. The technique is primarily used to treat male pattern baldness. In this minimally invasive procedure, grafts containing hair follicles that are genetically resistant to balding are transplanted to the bald scalp. Hair transplantation can also be used to restore eyelashes, eyebrows, beard hair, chest hair, pubic hair and to fill in scars caused by accidents or surgery such as face-lifts and previous hair transplants. Hair transplantation differs from skin grafting in that grafts contain almost all of the epidermis and dermis surrounding the hair follicle, and many tiny grafts are transplanted rather than a single strip of skin.
Electrosurgery is the application of a high-frequency alternating polarity, electrical current to biological tissue as a means to cut, coagulate, desiccate, or fulgurate tissue.. Its benefits include the ability to make precise cuts with limited blood loss. Electrosurgical devices are frequently used during surgical operations helping to prevent blood loss in hospital operating rooms or in outpatient procedures.
José Ignacio Barraquer Moner was a Spanish ophthalmologist and inventor born in Barcelona who did most of his life's work in Bogotá, Colombia.
Follicular unit extraction (FUE), also known as follicular transfer (FT), is one of two primary methods of obtaining hair follicles, naturally occurring groups of one to four hairs, for hair transplantation. The other method is called strip harvesting. Follicular Unit Extraction is an outdated term and has been redefined to Follicular Unit Excision. In 2018, Mejia published the updated guidelines adopted by the International Society of Hair Restoration Surgery. This name change came about to accurately describe the procedure which involves surgically cutting or incising a full thickness hair follicle skin graft with a circular scalpel, punch or motorized drill and subsequently carefully extracting it from the scalp to be placed in the donor balding scalp. Due to the new developments of incision punches and devices and a variety of different extraction techniques, it was necessary to more accurately define the procedure. Additionally, many places were incorrectly marketing the extraction procedure as a simple plucking of hairs and deceiving the public.
Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds or connect or remove parts of the bowels or lungs. The use of staples over sutures reduces the local inflammatory response, width of the wound, and time it takes to close.
Artificial skin is a collagen scaffold that induces regeneration of skin in mammals such as humans. The term was used in the late 1970s and early 1980s to describe a new treatment for massive burns. It was later discovered that treatment of deep skin wounds in adult animals and humans with this scaffold induces regeneration of the dermis. It has been developed commercially under the name Integra and is used in massively burned patients, during plastic surgery of the skin, and in treatment of chronic skin wounds.
Gingival grafting, also called gum grafting or periodontal plastic surgery, is a generic term for the performance of any of a number of periodontal surgical procedures in which the gum tissue is grafted. The aim may be to cover exposed root surfaces or merely to augment the band of keratinized tissue.
Fat transfer, also known as fat graft, lipomodelling, or fat injections, is a surgical process in which a person's own fat is transferred from one area of the body to another area. The major aim of this procedure is to improve or augment the area that has irregularities and grooves. Carried out under either general anesthesia or local anesthesia, the technique involves 3 main stages: fat harvesting, fat processing, fat injection.
