[The reconstruction of the oral and maxillofacial defects with free vascularized flaps and microsurgical anastomoses].

The reconstruction of the oral and maxillofacial defects is difficult, because of the high specialisation of the tissues. In cancer resection, the post-operatory defects are quite important, because of the oncological principle of assuring free margins. The free flap is a modem and nowadays very used method in oral and maxillofacial reconstruction, after the removal of the malignant tumors with this localisation. These flaps are indicated for large defects, when the reconstruction with local or regional flaps is not possible. The wide variety of the raised tissues allows better results, making them the flaps of choice for large defects of the lip and cheek. The main advantages are related to the tri-dimensional extension of the free margins, assuring the quality of life and allowing early initiation of the radiotherapy in oncological patients.
