Genders Eligible for Study
Description
Eligible participants are:
- Adult patients seeking treatment for nasal obstruction on one or both sides of the nose who are willing to undergo an office-based or intraoperative nasal implant procedure in lieu of alternative treatments (ie, surgical repair or use of an external dilator).
- Nasal valve collapse (NVC) must be a primary or significant contributor to the subject's nasal obstruction based on clinical presentation, physical examination and nasal endoscopy.
- Baseline Nasal Obstruction Symptom Evaluation (NOSE) score must be ≥55.
Participants are excluded for the following:
- Surgical or non-surgical treatment of the nasal valve or rhinoplasty within 12 months before enrollment.
- Septoplasty, inferior turbinate reduction, or other surgical nasal procedures within 6 months before enrollment.
- Recurrent nasal infections.
- Use of intranasal steroids within 2 weeks preimplant and 2 weeks post implantation.
- Presence of a permanent implant, dilator, or uses an external device in the nasal area.
- Cancerous or precancerous lesions and/or radiation exposure in the treatment area or chemotherapy within 24 months of the study.
- Significant bleeding disorders.
- Significant systemic diseases.
- Currently using nasal oxygen or continuous positive airway pressure (CPAP).

Breathing Capacity (NOSE Scores)
Time Frame: At baseline and at 6, 12, and 24 months post implant
|
Nasal breathing capacity was assessed using the validated Nasal Obstruction Symptom Evaluation (NOSE) questionnaire.
The NOSE score uses a 0-100 point scale to capture severity of nasal symptoms (congestion, obstruction, trouble breathing, sleeping, and exercise), with higher scores indicating more severe symptoms than lower scores.
NOSE severity classes are defined as Mild (5-25), Moderate (30-50), Severe (55-75), and Extreme (80-100).

NOSE Responder Rate
Time Frame: At 6, 12, and 24 months post implant
|
Percent of participants meeting responder criteria.
Responders are defined as participants with a reduction from baseline in 1 or more Nasal Obstruction Symptom Evaluation Score (NOSE) severity class or a 20% reduction in the NOSE score.
