Multiple Site Cryoablation Treatment of the Posterior Nasal Nerve for Treatment of Chronic Rhinitis: An Observational Feasibility Study.

ABSTRACT:

Background

Cryoablation of the posterior nasal nerve at the middle meatus has been shown to successfully treat nasal obstruction and symptoms of chronic rhinitis. Cryoablation of both the middle and inferior meatus has not yet been studied.

Objectives

To evaluate the safety and feasibility of cryoablation of the posterior nasal nerve at both the middle and inferior meatus locations to treat chronic rhinitis.

Methods

Participants underwent bilateral cryoablation of the posterior nasal nerve at both the middle meatus and inferior meatus and were assessed through 3 months post treatment. The primary endpoint is the change from baseline to 3-month follow-up in the reflective Total Nasal Symptom Score (rTNSS). Other assessments include additional patient-reported outcomes,
