Over the last several years, several exciting developments have occurred that may facilitate the use of the laser in reconstructive surgery. The goal of future research should be to make the procedure less operator-dependent (dye enhanced or automated welding). Another avenue of research would be to give the operator instantaneous feedback to assess parameters at the weld site to allow modification of the energy delivered. Currently, only color change of the tissue and experience provide the endpoints. With future research into these and other areas, laser welding continues to hold promise to become a useful adjunct in reconstructive surgery.
