Nasal Physiology
• Nasal airway is a resistor, responsible for 2/3 of airway resistance during wakefulness
• Internal nasal valve primary area of resistance, about 30% of cross sectional area at nares
• Bernoulli effect leads to greater negative pressure at nasal valve and greater collapse

Nasal Physiology
• Nasal mm provide some dilation and synchronize w respiration but role during sleep is likely limited
• Nasal resistance is position dependent and increases when supine
• Nasal “cycle” more pronounced supine
• Pressure on shoulder/hip causes ipsilateral congestion and contralateral decongestion

CONCLUSION There is substantial level 4 evidence to support the efficacy of modern-day rhinoplasty techniques for treatment of nasal obstruction due to nasal valve collapse. More recent studies have incorporated validated patient-reported outcome measures, with more rigorous statistical analysis. Future study design improvements include the use of comparison cohorts and incorporation of standardized objective outcome measures.

Clinical consensus statement: Diagnosis and management of nasal valve compromise
Otolaryngology–Head and Neck Surgery (2010) 143, 48-59 John S. Rhee, MD, MPH, Edward M. Weaver, MD, MPH, Stephen S. Park, MD, Shan R. Baker, MD, Peter A. Hilger, MD, J. David Kriet, MD, Craig Murakami, MD, Brent A. Senior, MD, Richard M. Rosenfeld, MD, MPH, and Danielle DiVittorio,
• NVC is a distinct clinical entity • NVC can be caused by: Alar or sidewall collapse, septal deviation,
columellar deformity, turbinate hypertrophy, ptotic nasal tip • Dx is by exam and Cottle type maneuvers and response to strips- adjunctive
tests such as radiographs, rhinomanometry etc were not helpful, but photography is helpful for documentation of deformities and endoscopy may be helpful to rule out other causes.
• Treatment is surgical • QOL measures such as NOSE are valid indicators of patient reported
success • Coding and billing is confusing

Conclusions
• NVC is common and treatable by both non-surgical and surgical means
• There is evidence to support the efficacy of a variety of functional rhinoplasty procedures in the treatment of NVC
