Abstract
Report the effects of photobiomodulation (PBM) and therapeutic ultrasound (TUS) on the viability of TRAM in mice. Materials and Methods: Fifty-five mice Swiss were subjected to treatment for 5 days. Group 1, treatment was performed with the agents switched off. Groups 2 to 5 were treated with different wavelengths 660 and 830 nanometers (nm) and groups 6 to 11 with TUS of 1 and 3 MHz frequency. Macrometric analyses were performed using a specific camera and analyzed by the ImageJ® software. Thermographic analyses were performed with the Flir C2 and analyzed using the FLIR Tools software. Results: Group 9 obtained 95% of viable area on the 3rd day and 85% on the 5th day, showing the effectiveness of the TUS in the flap viability. Regarding skin temperature, there was a difference only in the immediate postoperative period in group 1, which had a lower temperature than the other groups. Conclusions: TUS demonstrated greater efficiency in maintaining the viability of TRAM. PBM 830 nm also demonstrated good results in the viability of TRAM.
