Yellow and Infrared Low Level Light to Prevent Thyroidectomy Scar Formation
Researchers treated 35 thyroidectomy patients with a combination of 830 nm and 590 nm LED light. Patients received 60 J/cm over a period of 11 minutes for 7 days, starting on the day of surgery. After the first week, they received treatment 3x/week for 3 more weeks. At 3 months, scars on treated patients were lighter and had less color compared to controls. Self-assessment of scar was not significantly different between treated and control groups.
