Comparison study of a traditional pulsed dye laser versus a long‐pulsed dye laser in the treatment of early childhood hemangiomas

The role of pulsed dye laser (PDL) in the treatment of childhood hemangiomas is still controversial because of the inherent characteristics of hemangiomas as well as the side effects of the PDL. Recently, the long pulsed dye laser (LPDL) with cryogen spray cooling (CSC) has been found relatively more effective and safer than the PDL in the treatment of port‐wine stains and telangiectasia. This study was designed to compare the efficacy and complication rate of PDL versus LPDL for treating childhood hemangiomas.
