[Arterial vascularization of the nasal fossae].

An anatomical and neuroradiologic study was conducted to define arterial irrigation of the nasal fossae, the topography of the different vascular territories, particularly that supplied by territories, particularly that supplied by the internal maxillary artery which is by far the most important, and the anastomoses of the different endo- and extra-nasal internal and external carotid systems.
