Sample text

Collagen tightening was noted to be dependent on fluence and epidermal thickness. In the vertical plane, the UltraPulse CO2 laser induced an average of 43% tightening intraoperatively, which gradually diminished to an average of 34% at 6 months. Wound contracture following short-pulsed Erbium:YAG laser resurfacing was not seen until 1 month post-operatively, at which time 42% tightening was seen, gradually diminishing to 36% at 6 months. In the horizontal plane, the CO2 laser led to a 31% intraoperative tightening, decreasing to 19% at 6 months.

Microscopic investigation of the single-pulse impaction demonstrated a layer of thermal necrosis measuring 70±10 μm. Four weeks after laser treatment, the thickened epidermal layer appeared normal and the repaired papillary dermal collagen showed a relatively compact configuration with greater cellularity. The authors saw a histologic advantage in that this laser delivered short, sharp bursts of higher energy which rapidly and precisely heated targeted tissue with less resulting damage to adjacent tissue.

Silicone rubber skin surface impressions (profilometry) were taken prior to and at 4 months following laser treatment in five patients. Computer analysis of skin surface impressions correlated with clinical observations—a more substantial improvement was noted after UltraPulse laser treatment, compared to Surgipulse treatment. This study, in agreement with the previous studies, demonstrated the efficacy of pulsed carbon dioxide lasers in reducing periorbital wrinkles, both clinically and texturally.
