Outcomes

Primary Outcomes

Number of Participants With Procedure-related Serious Adverse Events (SAEs) and/or Serious Adverse Device Effects (SADE)

The outcome measure is the number of participants experiencing 1 or more SAEs/SADEs.

Time frame: Study duration (90-days)

Secondary Outcomes

Pain Scores

Tolerability of treatment as provided by the participant by verbal report of pain/discomfort during treatment and post treatment using an 11-point scale indicating pain intensity from 0 (no pain) to 10 (worst pain).

Time frame: Day of treatment during procedure and for up to 1 hour post procedure

Change From Baseline in the Reflective Total Nasal Symptom Score (rTNSS)

The rTNSS is a validated patient-reported outcome measure consisting of 4 symptoms: rhinorrhea, nasal congestion, nasal itching, and sneezing. Each item is scored on a scale of 0 (no symptoms) to 3 (severe symptoms). The total rTNSS is the sum of the 4 symptom scores and has a possible range of 0 to 12 points. The change from baseline is calculated as the follow-up value minus the baseline value. Negative values indicate improved symptoms.

Time frame: 30 and 90 days after treatment

Change From Baseline in the Overall Nasal Obstruction Symptom Evaluation (NOSE) Score

The NOSE survey is a patient-reported outcome measure consisting of 5 nasal symptoms: nasal congestion or stuffiness, nasal blockage or obstruction, trouble breathing through the nose, trouble sleeping, and unable to get enough air through the nose during exercise or exertion. Each symptom is scored using a 5-point scale of 0 (not a problem) to 4 (severe problem). The 5 symptom scores are summed and the total is multiplied by 5 to give a total score that ranges from 0 to 100, with higher scores indicating worse symptoms. The change from baseline is calculated as the follow-up value minus the baseline value. Negative values indicate improved symptoms.

Time frame: 30 and 90 days after treatment
