Introduction: head and neck cancer are very common entities of developing countries. In small or non complex defects we have a lot of options for reconstruction, like local or pedicle flaps, but when we consider big or complex defects microsurgery is necessary. Methods: in our casuistic, we have used radial forearm free flap for oral cavity, tongue and faryngeal defects, free anterolateral thigh flap with vastus lateralis muscle for maxilla defects and free fibula flap for mandible defects, between 20 patients. All flaps were done in the same institution and by the same surgical team. Results: the most common complications observed in microsurgical flaps like venous thrombosis and hematoma were not observed in this casuistic of 20 cases. Conclusion: microsurgical flaps for head and neck reconstruction represent an excellent alternative for big and complex defects, with low complication rates.
