While some specialists use the term “nasal obstruction” only when the nose has something physically blocking it, in general use it refers to the symptom of feeling that air cannot pass adequately through the nose [1]. Feeling that the nose is blocked can be the main complaint of patients suffering from a range of common disorders, including rhinitis, sinusitis, deviation of the septum, adenoidal hypertrophy, and traumatic injury to the nose [2]. © Springer Nature Switzerland AG 2023.eninfo:eu-repo/semantics/closedAccessBook Chapter10.1007/978-3-031-22483-6_16-112893032-s2.0-105002975056N/A
