Nasal valve stenosis commonly presents as a postoperative complication of rhinoplasty or facial trauma. Various techniques have been reported to correct nasal valve stenosis through the use of methods that support the nasal valve with cartilage, rib graft, although these tissues are not useful in some cases to improve the nasal breathing. The nasal valve functions as the law Starling resistor, which is a semirigid tube with a flexible segment, when the inspired partial pressure exceeds a critical level, it collapses and causes nasal obstruction, and therefore need some degree of rigidity in nasal lateral component to avoid collapse during inspiration. When the nasal valve is affected frequently causes nasal obstruction.

Palabras clave : Nasal valve collapse; nasal obstruction; rhinoplasty.
