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

Non-surgical treatment of NVC Dilator strips Intranasal stents Filler injections Radiofrequency lesion of lateral nasal sidewall
Nasal Obstruction Non Surgical Tx Ulfberg and Fenton: Rhinology 1997 35 pts, AHI <5, M,F, primary snorers, nasal obstruction Survey by bed-partner re: snoring ESS Significant decrease in snoring, dry mouth and ESS score after Breathe Right use
Breathe-Right Work best in patients with thin skin and flexible nasal sidewall

Eur Resp J. 2005;25:521-527 Randomised single blind placebo and sham controlled crossover study 10 patients with OSA and nasal obstruction (turbinate hypertrophy documented by exam) PSG, both oxymetazoline nose spray and Breathe Right strip vs saline and tape (sham) Posterior active rhinomanometry upright and supine
Nasal Obstruction Non Surgical Tx MaClean HA Eur Resp J. 2005;25:521-527 Nasal Resistance decreased profoundly with active Tx Oral fraction of inhaled ventilation decreased from 39 to 8 with active Tx AHI decreased by an average of 12 points, but only 1 fell below 15 Sleep architecture improved with REM % moving from 9% to 16% MaClean HA et al. Effect of Treating Severe Nasal Obstruction on the Severity of Obstructive Sleep Apnea. Eur Resp J. 2005;25:521-527 Concluded that Tx of nasal obstruction improved sleep but did not cure OSA

Does it work? John S. Rhee, Jill M. Arganbright, Brian T. McMullin and Maureen Hannley Evidence supporting functional rhinoplasty or nasal valve repair: A 25-year systematic review. Otolaryngology -- Head and Neck Surgery 2008 139: 10 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.

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
