Ablative Laser Skin Resurfacing (Invasive)
|
There is a considerable variety in the equipment and treatment techniques user for laser resurfacing. The two most common lasers for wrinkle removal are carbon dioxide and Erbium:YAG lasers. Carbon dioxide laser appears to be somewhat more effective for treating deep wrinkles but has longer recovery time and tends to cause greater adverse reactions. Some surgeons use both carbon dioxide and erbium:YAG lasers in the same procedure: erbium laser for fine lines and small wrinkles and carbon dioxide laser for deeper wrinkles. Such an approach may provide the best risk-to-benefit ratio. Another important technical aspect is the number of passes the surgeon makes when treating skin with a laser. Multiple passes, particularly with carbon dioxide laser, produce greater thermal injury and lead to greater side effects and longer recovery. Some surgeons assume that more passes results in a greater wrinkle reduction. However, research indicates that the benefit from additional passes may be small whereas additional risk is substantial. Some surgeons use a combination protocol where problem areas (around eyes, mouth and on the forehead) are first treated with one pass of carbon dioxide laser and then with one or more passes of less injurious erbium laser. The rest of the face may be treated with one pass of erbium laser. Recently, there are ablative fractional laser systems launched on the market. The fractional laser is the type of laser resurfacing using a technology which apply hundreds or thousands of microscopic laser columns -treat a fraction of the skin at a time without affecting the surrounding tissue in an attempt to retain the effectiveness of treatment as classic ablative laser resurfacing, but reduced invasiveness and the risk of side effect, downtime coming with the traditional ablative laser resurfacing procedures.

Ablative Laser Resurfacing – Postoperative CareLaser skin resurfacing (LSR) for the rejuvenation of facial skin remains a popular cosmetic procedure. Meticulous postoperative care is essential and is as important as intraoperative technique in achieving optimal results after laser ablation. Epidermal regeneration following the thermal injury of LSR is improved in a moist environment, since a dry crust or scab impedes keratinocyte migration.1 Both open and closed wound care methods can be applied to minimize morbidity and expedite postoperative wound healing. Numerous studies indicate that closed wound care regimens utilizing occlusive dressings for 48-72 hours postoperatively may hasten reepithelialization and reduce crusting, discomfort, erythema, and swelling.2-4 Appropriate medications and management techniques can also minimize the predictable effects of LSR. Resurfacing with carbon dioxide (CO2) or Erbium:YAG lasers results in ablation of the epidermis and upper papillary dermis. During reepithelialization, the wound produces copious serous discharge along with sloughing of denatured collagen. Resultant crusting may predispose the wound to secondary infection. Other immediate expected sequelae of LSR include discomfort, pruritus, erythema, and edema. Reepithelialization after resurfacing occurs at a mean of 8.5 days after CO2 and a mean of 5.5 days after Erbium:YAG lasers.5 Related Pages:
