Update on rhinitis and rhinosinusitis

Abstract Rhinitis is a common, under‐diagnosed condition in childhood and adolescence. Pathogenic classification of rhinitis includes allergic rhinitis (AR) and non‐allergic rhinitis (NAR); the latter is characterized by non‐infectious and infectious subtypes; non‐infectious subtype is by far the most prevalent in infancy. Endotyping may help to predict chronic rhinosinusitis (CRS) risk factors, as well as disease progression and response to different treatments. The validation of pediatric algorithms and the implementation of novel biotherapeutics in the endotype‐driven integrated pathways of CRS will lead in the next future to more successful disease management.
