Nasal valve surgery for nasal obstruction: A systematic review

Nasal obstruction is a common presentation at rhinology clinics. Aetiologies can widely vary from inflammatory, mechanical obstructive to structural/anatomical causes of nasal obstruction. Nasal valve collapse is a recognised cause of nasal path obstruction, whether presenting as the sole causative or as an addition to another obstructive aetiology. The identification of this cause of obstruction is essential in order to plan patients' management. In this article we aim to describe the anatomy, physiology and pathophysiology of the nasal valve area. Then we highlight what the commonly found surgical methods of addressing this issue in literature, and the documented outcomes.
