Conditions

Nasal Obstruction

Brief summary

This study is being conducted to obtain outcomes data in subjects with severe to extreme class NOSE scores undergoing placement of the Spirox Latera Implant with or without concurrent septoplasty and/or turbinate reduction procedures in an operating room setting.

Inclusion criteria

1. The subject has Nasal Obstruction Symptom Evaluation (NOSE) Score ≥55. 2. The subject has dynamic lateral nasal wall insufficiency as confirmed by Positive Modified Cottle Maneuver22. 3. The subject is ≥18 years of age. 4. The subject is willing and able to provide informed consent and comply with the study protocol. 5. The subject is seeking treatment for nasal airway obstruction due to Nasal Valve Collapse (NVC) and is willing to undergo nasal Implant procedure alone or with septoplasty and/or a turbinate reduction procedure in an operating room setting. 6. The subject has appropriate nasal and facial anatomy to receive Latera Implant. 7. The subject agrees to follow-up examinations through twelve (12) months post operatively. 8. The subject has failed a trial of appropriate maximal medical management \[e.g., nasal steroids (at least 4 weeks); antihistamines; oral decongestants; nasal strips, stents, or cones\]. Failure of maximal medical management may be from lack of effectiveness or inability of subject to tolerate.

Exclusion criteria

1. The subject is having a concurrent Functional Endoscopic Sinus Surgery (FESS) or sinuplasty. 2. The subject has had rhinoplasty within the past twelve (12) months. 3. The subject is planning to have other concurrent rhinoplasty procedure. 4. The subject is planning to have other rhinoplasty procedures or will use external dilators within twelve (12) months after the index procedure. 5. The subject has had septoplasty and/or inferior turbinate reduction within the past six (6) months. 6. The subject has, in the view of the clinician, inappropriate fixation on their nasal airway. 7. The subject plans to have any surgical or non-surgical treatment of their nasal valve, other than the index procedure, within twelve (12) months of the study. 8. The subject has a permanent Implant or dilator in the nasal area. 9. The subject has concomitant inflammatory or infectious skin conditions or unhealed wounds in the treatment area. 10. The subject currently has active nasal vestibulitis. 11. The subject has a history of nasal vasculitis. 12. The subject is a chronic systemic steroid or recreational intra-nasal drug user. 13. The subject has had a cancerous or pre-cancerous lesion and/or has had radiation exposure in the treatment area or chemotherapy. 14. The subject has polyps or pathology other than septal deviation and/or turbinate hypertrophy and/or lateral wall insufficiency that would contribute to airway obstruction. 15. The subject has a history of a significant bleeding disorder(s) that would prevent healing of the treatment area post procedure. 16. The subject has a known or suspected allergy to poly lactic acid (PLA) or other absorbable materials. 17. The subject has a significant systemic disease such as poorly controlled diabetes which, in the investigator's opinion, could pre-dispose the subject to poor wound healing. 18. The subject is currently using nasal oxygen or continuous positive airway pressure (CPAP). 19. The subject is not a candidate for procedures conducted under general anesthesia, managed anesthesia care (MAC) or conscious sedation. 20. If female, subject is known or suspected to be pregnant or is lactating.

Design outcomes

Primary

MeasureTime frameDescription
The Primary Efficacy Endpoint is the Percent of Treatment Responders6 months post procedureResponder is defined as a participant who has improvement of at least 1 Nasal Obstruction Symptom Evaluation (NOSE) class or at least 20% NOSE score reduction. NOSE scores. NOSE scores can range from 5 to 100, with higher scores indicating worse symptoms. Classes are mild (5-25), moderate (30-50), severe (55-75), and severe (80-100).

Participants provide scores on a scale of 0 (easy to breathe through the nose) to 100 (unable to breathe through the nose). Negative values for the change from baseline indicate improvement in symptoms.
Subject Satisfaction Questionnaire6 monthsParticipants rate whether they are satisfied or not satisfied with the procedure and cosmetic appearance after the procedure. The percent of participants reporting satisfaction with the procedure is reported.
