title: [Radiologic study of the nasal fossa. Value of a vasoconstrictor test].
abstract: The advantages of a vasoconstrictor test during standard radiologic imaging of the nasal fossae are discussed. After a brief anatomic and physiologic review, results are presented of the use of a prednazoline test in 23 patients with radiologically evident nasal obstruction. Results emphasize the diagnostic value of the use of the vasoconstrictor, which enables precise study of morphology of the nasal fossae and, in certain cases, their functional exploration.
