Nasal Airflow Resistance

  • Nasal valve area is the narrowest region of nasal airway⁶
  • Most common site of nasal airway obstruction⁶
  • Accounts for 2/3 of nasal resistance⁶

Small changes make large improvements to
nasal breathing


Bernoulli’s Principle: Increase in airflow velocity leads to a decrease in pressure

Poiseuille’s Law: Airflow is proportional to the 4th power of the change in radius

VivAer Stylus: Comprehensive treatment

Treating anterior anatomy to open the nasal airway

  • Durably remodels soft tissue, including cartilage, in the nasal valve
  • Increases the radius of the nasal valve to improve breathing
  • Shrinks submucosal tissue of the inferior Turbinate
  • Reduces soft tissue obstruction on the septum
  • Treatment does not alter patient aesthetics

Clinically proven durable results
and high patient satisfaction


Statistically significant improvement shown in prospective, multicenter study:³

  • 89% report improved sleep quality
  • 94% report improved ability to breathe through their nose during exercise or exertion

Which patients can benefit most from this procedure?


  • Patients who have a NOSE score >60 and experience improvement with the modified Cottle’s maneuver
  • Postsurgical patients who have undergone nasal obstruction surgery and still have difficulty breathing
  • Surgically naïve patients who wish to avoid traditional surgery and a lengthy recovery
  • Adjunct to surgery patients who are candidates for traditional surgery (e.g., septum, turbinates) and respond well to modified Cottle’s maneuver
