Abstract/OtherAbstract:
Each of the increasing number of resurfacing lasers uses a unique strategy to produce tissue ablation. Erbium:YAG (Er:YAG) lasers have been used in other applications for precise tissue removal with little thermal effect. Recovery time, duration of erythema, and clinical improvement were evaluated using an Er:YAG resurfacing laser (2.94-microm wavelength, 350-microsec pulse, 2 J, 3-5-mm spot). Twenty-five patients were treated with two passes to the full face and 3 to 5 passes to the most affected aesthetic unit. At each follow-up visit, percent epithelialization, erythema, and swelling were graded, and the presence or absence of complications was noted. Clinical improvement was evaluated at 6 months by optical profilometry on a subset of patients. Er:YAG resurfacing produced a transient whitening of dermis followed by a resumption of pink appearance. The surgical end point was judged by elimination of visible rhytids or presence of punctate bleeding. Bleeding from the dermal surface was encountered less than customarily in dermabrasion, but more than seen with carbon dioxide laser resurfacing. A moderate amount of tissue shrinkage was observable during the treatment. Mean period to full epithelialization was 6.9+/-0.97 days (range, 5-9 days). The mean duration of erythema (4.24+/-1.5 weeks) was relatively short compared with carbon dioxide resurfacing. Clinical improvement was 44+/-30% in the lateral canthal area and 55+/-22% in the upper lip area. There were no infections or hypertrophic scars. Hyperpigmentation and hypopigmentation was seen in 24% and 12% of patients respectively. Er:YAG resurfacing is a reliable means of obtaining rhytid improvement with less recovery time and duration of erythema compared with carbon dioxide resurfacing. The technique is significantly different from carbon dioxide resurfacing in selection of end point, number of passes, and energy settings.
