- Accepts Healthy Volunteers
- No
Inclusion Criteria
- •The subject has Nasal Obstruction Symptom Evaluation (NOSE) score ≥
- •The subject has dynamic lateral nasal wall insufficiency as confirmed by positive modified Cottle maneuver.
- •The subject is ≥18 years of age.
- •The subject is willing and able to provide informed consent and comply with the study protocol.
- •The subject is seeking treatment for nasal airway obstruction due to nasal valve collapse (NVC) and is willing to undergo an in-office nasal implant procedure alone or with a turbinate reduction procedure.
- •The subject has appropriate nasal and facial anatomy to receive the Latera Implant.
- •The subject agrees to follow-up examinations through 12 months post operatively.
- •The subject has failed to benefit from appropriate maximal medical management [eg, nasal steroids (at least 4 weeks); antihistamines; oral decongestants; nasal strips, stents, or cones]. Failure of maximal medical management may be from lack of effectiveness or tolerability.
Exclusion Criteria
- •The subject is having a concurrent functional endoscopic sinus surgery (FESS) or sinuplasty.
- •The subject has had rhinoplasty within the past 12 months.
- •The subject is planning to have other concurrent rhinoplasty procedure.
- •The subject is planning to have other rhinoplasty procedures or will use external dilators within 12 months after the index procedure.
- •The subject has had septoplasty and/or inferior turbinate reduction within the past 6 months.
- •The subject has, in the view of the clinician, inappropriate fixation on their nasal airway.
- •The subject plans to have any surgical or nonsurgical treatment of their nasal valve, other than the index procedure, within 12 months of the study.
- •The subject has a permanent Implant or dilator in the nasal area.
- •The subject has concomitant inflammatory or infectious skin conditions or unhealed wounds in the treatment area.
- •The subject currently has active nasal vestibulitis.
- •The subject has a history of nasal vasculitis.
- •The subject is a chronic systemic steroid or recreational intranasal drug user.
- •The subject has had a cancerous or precancerous lesion and/or has had radiation exposure in the treatment area or chemotherapy.
- •The subject has polyps or pathology (ie, septal deviation) other than turbinate hypertrophy and/or lateral wall insufficiency that would contribute to airway obstruction.
- •The subject has a history of a significant bleeding disorder(s) that would prevent healing of the treatment area post procedure.
- •The subject has a known or suspected allergy to polylactide polymer (PLA) or other absorbable materials.
- •The subject has a significant systemic disease such as poorly controlled diabetes which, in the investigator's opinion, could predispose the subject to poor wound healing.
- •The subject is currently using nasal oxygen or continuous positive airway pressure (CPAP).
- •The subject is not a candidate for procedures conducted under local anesthesia and/or managed anesthesia care (MAC) or conscious sedation.
- •Female subjects of childbearing potential, known or suspected to be pregnant, or is lactating.
Outcomes
Primary Outcomes
Safety: Procedure- and/or Device-related Adverse Events
Time Frame: 6 months
Number of participants with 1 or more adverse events that are determined to be related to the Latera implant and/or procedure.
Efficacy: Percent of Treatment Responders
Time Frame: 6 months
A responder is defined as a participant who has an improvement of at least 1 NOSE class or a NOSE score reduction of at least 20% compared with baseline. NOSE scores can range from 0 to 100 with higher scores indicating worse symptoms. Classes are mild (5-25), moderate (30-50), severe (55-75) and extreme (80-100).
Secondary Outcomes
- Change in Nasal Airway Obstruction From Baseline Using a Visual Analog Scale (VAS)(1, 3, 6, 12, 18, and 24 months post procedure)
- Percent of Treatment Responders(1, 3, 12, 18, and 24 months post procedure.)
- Subject Satisfaction Questionnaire(6 months)
- Procedure and Device-related Adverse Events(After 6 months and up to 12 months post procedure)
