Vascular lesions of the paranasal sinuses and nasal cavity.
The vascular supply to the face and paranasal sinuses is predominantly derived from branches of the external carotid artery. An extensive collateral arterial network exists between branches of the external carotid artery and the internal carotid artery that is important in the assessment of head and neck vascular disease. We illustrate the normal vascular anatomy and correlate cross-sectional and angiographic images of head and neck vascular disease, with a focus on lesions affecting the paranasal sinuses and nasal cavity.
