Methods: Retrospective descriptive cohort study over a period of 4 years, including children, who consulted for epistaxis at the ENT and CCF department of FSI Hospital, La Marsa Tunis. All cases were divided into 2 groups: ERA+ Group: epistaxis with allergic rhinitis versus ERA- Group: epistaxis without allergic rhinitis.
