Many laser wavelengths with various power and pulse characteristics have been used in an attempt to improve cutaneous scars. No single configuration has produced such dramatic changes in quality of life as the high energy, low density, sub-millisecond pulsed ablative infrared laser. Hundreds of wounded military service members with burn and traumatic scars that resulted in disabling restriction in range of motion have been treated since 2008. By fractionating the pulse to produce a uniform thermal injury less than 400um wide and to a depth of 3mm into the scar, we have observed dramatic reductions in scar-induced pain, pruritus, and most significantly, improvements in range of motion. The clinical and histologic changes seen in restrictive scars following treatment correlates with a regeneration of tissue that appears and functions more like normal tissue rather than scar. This lecture will describe our experience in the military and the latest research to support our observations.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
