title: [Does the use of nasal vasoconstrictor agents change tomodensitometric images of nasosinusal polyposis?].
abstract: This study compared the results of the CT scan of the paranasal sinuses in nasal polyposis patients before and after a topical vasoconstrictor application on the nasal mucosa. No change have been observed either on the maxillary and ethmoidal sinuses, or the middle meatus. On the other hand, an important retraction was observed on the nasal mucosa, in particular on the inferior turbinate. Then, the application of a topical vasoconstrictor on the nasal mucosa does not seem necessary in order to explore the sinuses in patients with nasal polyposis.
