Rhino-sinobronchial syndrome

The intra- and extra-thoracic airways have a common embryological origin - 2(nd)-4(th) branchial pouch - and a continuity that ensures the conditioning and the conduct of airflow to the alveoli. It is this continuity that explains the common pathological events having a cause and effect type of relationship, such as is the case with rhino-sinobronchial syndrome. This syndrome has a multifactorial pathogenesis frequently with an allergic component, for which the time for resolution can exceed 12 weeks - a fact which must be included in the differential diagnosis of severe and bronchial asthma, especially in cases of difficult management or resolution. Interaction between the pulmonologist and otolaryngologist is thus fundamental for a correct patient management.
