Abstract
We have investigated the utilization of high incident fluence, long pulse laser irradiation in conjunction with cryogen spray cooling (CSC) on ex-vivo human skin. Abdominal skin samples of different types (Fitzpatrick type I-VI) were obtained from patients undergoing the trans-rectus myocutaneoues flap procedures. Each skin type was irradiated with a Candela Vbeam™ laser (wavelength λ-595 nm) at incident dosages of D0=6, 10, 15, 20 J/cm2, pulse durations of τlaser=1.5, 10, 40 ms, without and with CSC. Preliminary results indicate that lightly pigmented skins can sustain higher incident fluence levels than those currently used in therapeutic settings. While the incident dosage of the laser pulse remains the same, longer pulse duration can decrease the degree of epidermal thermal injury.
