Laser plastic surgery not only restores the function of the body, but also improves the appearance. Its object is congenital or acquired defects and deformities of tissues and organs, skin and soft tissues, musculoskeletal, and sequelae of some diseases.
In plastic surgery, postoperative bleeding and hematoma formation are important obstacles in plastic surgery, and sometimes even minor bleeding will affect the success or failure of surgery. Laser plastic surgery can seal small blood vessels and make the operation area almost completely bloodless. Doctors can master the laser dose according to the skin thickness of different areas and the depth of lesions to be removed, which can effectively prevent postoperative scars. Laser can destroy bacteria when cutting or gasifying wounds, so as not to cause wound infection and wound healing quickly.
Laser shaping has a wide range of applications, but it can be divided into two categories: laser cutting and laser gasification. Most of them are suitable for laser cutting, such as deep lesions and deep plastic surgery, such as benign and malignant skin tumors, double eyelid plasty and abdominal liposuction. Laser vaporization is suitable for treating superficial skin lesions and cosmetic surgery. Such as freckles, chloasma, wrinkles, various scars, pigmented nevus, too short lingual frenulum, abnormal wart, flat wart, etc.
Taking laser nevus removal as an example, the doctor only needs to aim the focused laser beam at the lesion for one or two minutes, and the part with nevus will vaporize at high energy. After the operation, no special treatment is needed. The doctor just put some ointment on the wound and told it not to get wet for a week. About a week later, the keloid fell off and the pigmented nevus was completely removed. In the Union Medical College Hospital affiliated to Tongji University in China, more than 300 patients with facial pigmented nevus have been treated with carbon dioxide laser for more than 10 years, and all of them have achieved satisfactory results, of which 279 cases even left no trace.
Some cosmetic surgery that traditional surgery can't handle can also consider using lasers. Such as the treatment of abnormal skin color, traditional methods are powerless. There are many patients with abnormal skin color, such as pigmented spots, hemangioma, discoloration of transplanted skin and scars, which often become the biggest distress of patients. Nd: Glass, copper vapor and dye laser have stronger effects on discolored skin than normal skin, and can only remove abnormal tone without damaging the function and shape of skin. Candeira Laser Company of the United States claims to have manufactured a new type of laser, which can eliminate benign pigmented lesions, without scars and white spots, and emphasizes that this is the first product of its kind that has been strictly evaluated by the Federal Food and Drug Administration and obtained a license certificate. This instrument was first welcomed by white people, because 70% of them have ugly freckles and age spots. According to a doctor in charge of clinical examination, the average cure rate is 85 ~ 90%.
