The Vivaer Procedure for Treatment of the Septal Swell Bodies (SWELL)

Inclusion Criteria: 1. Age 22 to 85 years (inclusively). 2. Seeking treatment for nasal obstruction and willing to undergo an office-based procedure. 3. Baseline NOSE score ≥ 55. 4. Presence of SSB hypertrophy limiting visualization of the middle turbinate (MT) by more than 50%. 5. Reduction in size of the SSB after application of topical decongestant on a cotton plug directly to the SSB region. 6. Improvement in the symptoms of nasal obstruction after SSB decongestion suggesting that the SSB may play a role in nasal obstruction. 7. Willing and able to withhold anticoagulant medications during the perioperative period (3-day window on either side). 8. Willing and able to provide informed consent. 9. Willing and able to comply with the participant-specific requirements outlined in the study protocol. Exclusion Criteria: 1. Rhinoplasty, septoplasty, inferior turbinate (IT) reduction, or other surgical nasal procedures within the preceding 6 months. 2. Severe case of any of the following: septal deviation, turbinate hypertrophy, polyps, or ptotic nose tip believed to be the primary contributor to the participant's nasal obstruction symptoms and warranting surgical intervention. 3. Any adjunctive surgical nasal procedure planned on the same day or within 3 months after the Vivaer procedure. 4. Known or suspected allergies or contraindications for any general or local anesthetic agents. 5. Known or suspected to be pregnant or is lactating. 6. Participating in another clinical research study. 7. Other medical conditions which in the opinion of the investigator would predispose the participant to poor wound healing or increased surgical risk, or poor compliance with the requirements of the study. 8. Known or suspected regular use of oxymetazoline (Afrin) nasal decongestant or oral steroids. 9. For sites participating in the CT substudy only: Active sinus condition (eg, significant sinus diseases, infection or polyp formation) identified by CT.
