Endoscopy is a surgical technique that uses a special endoscope that allows the surgeon to see the structures inside the body through a small incision through the endoscope. Endoscopy has been used in surgical procedures for decades. This includes gallbladder removal, duct ligation and joint surgery. The involvement of endoscopic technology in cosmetic surgery began in the mid-1990s and became popular throughout Europe and the United States after its many advantages became apparent. In recent years, a few hospitals in China have been carrying out some endoscopically guided surgeries, and its rapid development is entirely due to the obvious superiority of the endoscope and the assistance of special surgical instruments, which traditionally require large incisions, can be completed with only a small wound. This not only reduces the invasiveness of the procedure, but also increases the precision and safety of the procedure, thus greatly increasing the patient’s acceptance of the procedure. The endoscope consists of two basic parts: a tubular probe attached to a small camera and a bright light source that is inserted through a small incision; and a fluorescent screen that displays a magnified image of the internal structures of the body. During the procedure, the surgeon moves the endoscopic catheter around the surgical area while gazing at the fluoroscopic screen. The endoscope is only a viewing tool and another set of surgical instruments such as a blade, scissors or vascular forceps are inserted and manipulated through another incision while the procedure is performed. Endoscopic procedures have smaller scars that are easy to hide and can have fewer post-operative side effects. A typical endoscopic procedure requires only a few small incisions, each less than 2.5 cm long, for the insertion of the endoscope and other instruments. The surgeon’s view from the endoscope is almost as clear as the view from the incision. Because the endoscopic incision is shorter, the risk of sensory loss due to nerve damage is also reduced. In addition, bleeding, bruising and swelling can be greatly reduced. Patients who undergo endoscopic surgery can recover faster and return to work sooner than those who undergo incision. Endoscopy requires a high level of skill from a surgeon, firstly he must have good aesthetic training to make the plastic part perfect; secondly he must also have good anatomical knowledge; and of course he must be skilled in minimally invasive endoscopic techniques. Only with the perfect combination of these three points can perfect results be achieved. Procedures that can be assisted with endoscopy: Wrinkle Reduction – Of all the cosmetic surgical procedures that use endoscopy, wrinkle reduction is one of the most commonly performed. While the traditional face lift remains the best option for most patients, especially those with excess skin. However, some selective patients can also benefit from endoscopic procedures. With the help of endoscopic technology, frontotemporal wrinkle reduction surgery replaces the previous dozen centimeter-long coronal incisions with three short incisions in the hairline. Under endoscopic guidance, the surgeon removes the muscles causing the forehead wrinkles and raises both eyebrows in a new position with much less recovery time and with results that are no less impressive than the former. Breast augmentation – especially implants are placed through an axillary or navel incision. The incision can be made smaller and more concealed, so that the hemostasis and breast augmentation position is more precise and the result is more perfect. Especially with teardrop shaped implants, it is very difficult to place the implants by feel alone, but with the endoscope under direct vision it is easy to place the implants in the correct direction. The endoscope can also assist in the management of peri-implant contracture (the formation of scar tissue around the implant that hardens it). It can also be used to examine the condition of the prosthesis. In addition, endoscopic techniques can be used to assist in facial contouring procedures, placement of cheek and chin prostheses, etc.
