Summary
An absorbable implant for nasal valve collapse (NVC) shows promising safety and effectiveness. This treatment significantly improved patient-reported outcomes in a 12-month study.
Area of Science:
- Otolaryngology
- Rhinology
- Biomaterials Science
Background:
- Nasal valve collapse (NVC) significantly impacts breathing and quality of life.
- Current treatments for NVC have limitations, necessitating novel approaches.
- Lateral cartilage support is crucial for nasal airway patency.
Purpose of the Study:
- To assess the safety and efficacy of a novel absorbable implant for lateral cartilage support in NVC patients.
- To evaluate patient-reported outcomes using the Nasal Obstruction Symptom Evaluation (NOSE) score.
- To determine the long-term (12-month) results of this innovative NVC treatment.
Main Methods:
- A prospective study involving 30 subjects with NVC and high NOSE scores (≥55).
- Treatment involved placement of a polylactic acid copolymer implant using a delivery tool.
- Procedures were performed under general or local anesthesia, with 12-month follow-up.
Main Results:
- A significant reduction in mean NOSE scores from 76.7 to 35.2 at 12 months was observed.
- 76% of subjects were classified as responders, indicating meaningful improvement.
- No adverse cosmetic changes were noted; three implants required early retrieval without sequelae.
Conclusions:
- The absorbable implant is a safe and effective option for providing lateral cartilage support in NVC.
- The implant demonstrates sustained improvement in nasal obstruction symptoms at 12 months.
- This study supports the use of absorbable implants as a viable treatment for nasal valve collapse.
