Absorbable implant to treat nasal valve collapse.
Nasal valve collapse (NVC) attributed to weak lateral cartilage is a common cause of nasal airway obstruction. However, due to complex surgical techniques for correcting NVC and associated cosmetic consequences, NVC frequently remains untreated.17 This study presents a first-in-human experience using the LATERA® absorbable nasal implant to support the lateral nasal cartilage. The ability of the implant to provide sufficient lateral cartilage support is demonstrated by a significant reduction in NOSE scores through 18 months of follow-up with an acceptable safety profile.
Study design and overview
- Assessed quality of life for nasal airway obstruction (NAO) patients using the validated NOSE score16,19
- Prospective, multi-center, single cohort study in Germany
- 30 subjects with Nasal Valve Collapse, treated only with the LATERA implant (56 implants)
- Majority of patients had previous nasal surgeries
- Subjects were treated under general or local anesthesia
Demographics and Procedure Background
|Baseline NOSE score||76.7 ± 14.8||Nasal surgical history|
|All Subjects||Yes||19 (63.3%)|
|Age (year)||51.1 ± 14.5||Sides treated|
|Female||12 (40.0%)||OP/ITN||14 (46.7%)|
|Male||18 (60.0%)||Office/LA||16 (53.3%)|
This study demonstrated the safety and effectiveness of an absorbable implant for lateral cartilage support in subjects with NVC at 18 months post procedure.
1. Durable results16 within the range of other nasal obstruction techniques.18
2. Effective in severely or extremely symptomatic patients.
3. Well-tolerated with an acceptable safety profile and without adverse cosmetic impact at 6, 12 and 18 months.
a Study follow-up is ongoing for 27 patients. Three patients exited the study early.
b One subject did not record a pain assessment at 6 mos.
c Device-related AE’s includes 3 device retrievals, 1 hematoma, and 1 inflammation.
d Independent reviewer noted alar retraction in 1 patient, which was not observed subsequently at 6, 12 or 18 months.
Risks included mild bruising and inflammation, awareness of the implant, mild pain or irritation, discomfort, infection, reaction to material and device retrieval. The limitations of this study included a modest sample size, nonrandomized study design and a heterogeneous subject population with respect to prior history of nasal surgery.
