[Clinical application of free microvascular flaps in reconstructive surgery of the oral cavity].

We present the results of reconstructive surgery after different surgical resections in the oral cavity. Reconstruction of the defects was made using free microvascularized flaps. We used a free radial fasciocutaneous or osteocutaneous flap in every case, with a 100% of viability and a low complication rate. This technique is widely versatile in the reconstruction of different oral defects, offering an adequate replacement of oral mucosa.
