The effect of light-emitting diode (590/830 nm)−based low-level laser therapy on posttraumatic edema of facial bone fracture patients

LED-based LLLT is recently receiving attention worldwide for its cost-effectiveness and large coverage area compared to traditional laser therapy. Recent studies support its effectiveness in various areas such as wound healing, skin rejuvenation, and pain alleviation. In this study, we treated facial bone fracture patients with LED-based LLLT, and showed its effectiveness in reducing posttraumatic edema.
