Evaluation of Photobiomodulation on Nasal Fractures

Nasal fractures are one of the most incidental of facial traumas. Regression of nasal edema is necessary so that surgical reduction of the fracture can be performed. It is known that photobiomodulation (PBM) reduces pain, edema and modulates inflammation. Regression of edema in a shorter time may decrease hospitalization time, decreasing hospital costs. However, there are no well-designed clinical studies on this subject. Therefore, the objective of this study will be to evaluate if PBM is able to reduce edema in the region of fractured nasal bones prior to nasal reduction and nasal packing, in order to reduce the patient's ability to go through surgery. Thirty-six patients diagnosed with a (primary) nasal fracture admitted to the Mandaqui Hospital Complex whose trauma occurred in the last 48 hours will be randomly divided into: G1- (control) (n = 18). . G2-Light emitter diode (LED) group (n = 18) - The standard hospital treatment will be performed + LED nasal mask. The main variable will be the edema evaluated by the same researcher and with the same technique. Secondary variables will be pain (visual analogue scale - VAS), temperature, rescue medication count, serum C-reactive protein and systemic inflammatory cytokines. Afterwards, the LED or its placebo will also be applied. The questionnaire to assess the impact of treatment on quality of life will be applied at the baseline and after 8 days. Adverse effects will be recorded and reported. If the data is normal, they will be submitted to Student's t-test. The data will be presented by their means ± standard deviation (SD) and the value of p will be set at 0.05.
