Report the effects of photobiomodulation (PBM) and therapeutic ultrasound (TUS) on the viability of TRAM in mice.
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.
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.
TUS demonstrated greater efficiency in maintaining the viability of TRAM. PBM 830 nm also demonstrated good results in the viability of TRAM.
报告光生物调节（PBM）和治疗性超声（TUS）对小鼠游离皮瓣存活率的影响。
55 只瑞士小鼠接受了为期 5 天的治疗。第 1 组，治疗仪器关闭；第 2 至 5 组分别接受不同波长 660 和 830nm 的治疗；第 6 至 11 组接受 1 和 3MHz 频率的 TUS 治疗。使用特定的相机进行宏观分析，并使用 ImageJ®软件进行分析。使用 Flir C2 进行热成像分析，并使用 FLIR Tools 软件进行分析。
第 9 组在第 3 天获得了 95%的存活区域，在第 5 天获得了 85%的存活区域，表明 TUS 对皮瓣存活率的有效性。关于皮肤温度，仅在第 1 组的即刻术后期间存在差异，其温度低于其他组。
TUS 显示出在维持游离皮瓣存活率方面更有效。PBM 830nm 也显示出对游离皮瓣存活率的良好效果。
