title: The nasal arteries.
abstract: Thorough knowledge of the normal gross and radiographic anatomy of the nasal fossa is a prerequisite for correct interpretation of external carotid angiograms in patients with lesions in or adjacent to the nasal cavity. This report describes in detail the normal gross and angiographic vascular anatomy of the nasal fossa. The appearance of the sphenopalatine artery and nasal branches of the ethmoidal arteries in a variety of lesions that affect the nasal cavity, nasopharynx, and adjacent structures is also discussed. Typical changes in acute rhinitis, sinusitis, sphenopalatine neuralgia, vascular malformations, neoplasms, and benign bulky nasal masses are illustrated.
