The skull base reconstruction should achieve a complete sealing of the defect and make the nasosinusal territory independent of the cranial cavity, thus avoiding the appearance of cerebrospinal fluid leak and possible intracranial complications. 

The vascularized flaps, local or regional, provide a vital tissue of high quality that allows to carry out definitive reconstructions in a more reliable way, minimizing the problems of scarring and tissue necrosis. 

In this course, anatomy-surgical references and vascularization of the nasal septum and nasal lateral wall will be reviewed in anatomical samples. Each participant will have the opportunity to perform all types of vascularized flaps. This dissection will be supervised by our faculties.
