Small study tests laser vs. punch biopsy for burn scars

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients must be 18 years of age or older * Must be medically fit to undergo laser/reconstructive procedure * Must have symptomatic HTBS for which they are already planning to undergo laser treatment. The symptomatic HTBSs may include the study scar area, but there must be other areas that the patient is getting treated with laser besides the study scar. * The HTBS must have occurred from a burn injured area either treated by skin grafts or allowed to heal secondarily. * Be willing and able to participate in the study with a year of follow-up * Must be able to answer surveys on their own, and not rely on surrogates * Not be pregnant or planning to become pregnant during the treatment phase of the study Study Scar Inclusion Criteria: * The study scar must be at least 3mm thick * For Extremities, no surgical treatment can be performed on joint space above or below the target area * If the study scar is over a joint, then no surgical treatments can occur to the body part above or below it * When the study scar is on the trunk or neck, it must not be on continuity or adjacent to any area of planned surgical treatment. * Study Scar Size: The study scar can either be within an area of homogenous HTBS or be an area of HTBS surrounded by normal tissue if it meets the following size criteria: * Within HTBS For treatment areas within burn scars, it must be 65cm2 or larger to permit 3 treatment areas that are 3 x 3cm with a 1cm wide segment of untreated scar between it. * Surrounded by normal tissue For treatment areas surrounded by normal skin, the treatment area must be 33cm2 or greater, contain similar 3x3cm treatment areas, and have intervening segments of 1cm of scar between treatment areas. A border around the scar, is not required here because it is surrounded by normal skin. Exclusion Criteria: * Previous laser or reconstructive procedures for the treatment of their HTBS in the study scar or adjacent tissue. * Steroids, immunosuppressive medications, chemotherapy or other medications that can delay their wound healing/immune function. * Medical Conditions that preclude laser treatment or general anesthesia if needed * Cognitively unable to complete PROMs on their own * The study area should not be part of a contracture or other hypertrophic scar that would be better treated with surgical procedures. * The study scar must not be adjacent to/in continuity with areas of HTBS that are planning to be treated with surgical interventions.
