Temperature-controlled radiofrequency device treatment of the nasal valve for nasal airway obstruction: A randomized controlled trial.

ABSTRACT:

Background

Nasal valve collapse is one of several causes of nasal obstruction. The safety and efficacy of a temperature-controlled radiofrequency (RF) device for the treatment of the nasal valve for nasal airway obstruction (NAO) has been established in single-arm studies. The objective of this trial was to compare active device treatment against a sham procedure (control).

Methods

In a prospective, multicenter, single-blinded, randomized controlled trial (RCT), patients were assigned to bilateral temperature-controlled RF treatment of the nasal valve (n = 77) or a sham procedure (n = 41), in which no RF energy was transferred to the device/treatment area. The device was applied to the mucosa over the lower lateral cartilage on the lateral nasal wall. The primary endpoint wa
