Abstract

BackgroundWeak or inward-bent cartilage of the nasal sidewall at the level of the internal nasal valve (INV) can produce narrowness or collapse of the nasal valve. This is a common cause of impaired nasal breathing during daily activities and there is also an established connection between nasal obstruction and snoring. The condition is often difficult to treat, although even a small enlargement of the lumen at the nasal valve can lead to a significant improvement in the ease of nasal breathing.MethodsThe primary objective of this prospective study was to evaluate the safety and efficacy of the Vivaer system for the treatment of narrowed nasal valves and to measure changes in the symptoms of nasal obstruction and snoring. The Vivaer system uses low energy radiofrequency to remodel the nasal sidewall in order to improve airflow.ResultsThe study involved 31 patients presenting from 1st September 2017 to 1st May 2018 with symptoms of nasal obstruction and snoring. In all patients, an improvement was observed in nasal breathing measured by NOSE score, sleep quality by SOS questionnaire and quality of life as measured by EQ-5D and SNOT-22.ConclusionVivaer intranasal remodeling can provide a durable and well-tolerated non-invasive treatment for those patients who are suffering congestion due to narrowness or collapse of the INV.

Highlights

Impaired nasal breathing is a common reason for patients’ consultations to the ENT physician and is considered by those affected to cause significant reduction in their quality of life [1]
We aim to investigate the effect of using isolated intranasal remodeling of the internal nasal valve (INV) on measures of nasal breathing and snoring
We looked at improvement in terms of a patients potential down-stepping to a lower nasal obstruction severity level

Summary

Introduction

Impaired nasal breathing is a common reason for patients’ consultations to the ENT physician and is considered by those affected to cause significant reduction in their quality of life [1]. Weak or inward-bent cartilage of the nasal sidewall at the level of the internal nasal valve (INV) can produce narrowness or collapse of the nasal valve. This is a common cause of impaired nasal breathing during daily activities and there is an established connection between nasal obstruction and snoring. Methods The primary objective of this prospective study was to evaluate the safety and efficacy of the Vivaer system for the treatment of narrowed nasal valves and to measure changes in the symptoms of nasal obstruction and snoring.
