Effect of Photobiomodulation on Ecchymosis after Rhinoplasty: A Randomized Single-Blind Controlled Trial.

[BACKGROUND] This study was conducted to compare the effect of photobiomodulation therapy (low-level laser therapy) on ecchymosis after rhinoplasty.

[SUBJECTS AND METHODS] Sixty rhinoplasty candidates were randomly divided into two groups. Photobiomodulation, including red light (660 nm), infrared light (840 nm), and infrared laser, was used in the first group on the first postoperative day, and its effect on periorbital ecchymosis was evaluated.

[RESULTS] The findings showed that low-power laser reduced ecchymosis significantly (p = 0.005).

[CONCLUSION] Photobiomodulation may be effectively used for reducing ecchymosis after rhinoplasty.
