Nasal valve collapse is a structural condition characterized by narrowing or loss of integrity in the nasal valve area, which is the narrowest region of the nasal airway. This narrowing leads to impaired airflow and chronic nasal obstruction.{{cite journal | vauthors = White PS, Hussain SS, Spielmann PM | title = Surgical techniques for the treatment of nasal valve collapse: A Systematic Review | journal = The Laryngoscope | volume = 119 | issue = 7 | pages = 1281–1290 | date = 2009 | pmid = 19422026 | doi = 10.1002/lary.20495 | url = https://onlinelibrary.wiley.com/doi/10.1002/lary.20495 | issn = 0023-852X | access-date = 2025-04-25 | url-access = subscription }}
External nasal valve collapse
External nasal valve collapse is a structural disorder involving insufficient support of the lateral nasal wall (the ala of the nose), resulting in narrowing or collapse of the nasal airway during inspiration.{{cite book | last=Celebi | first=Özlem Önerci | last2=Önerci | first2=T.
