Modified Technique Improves Efficacy for In-office Posterior Nasal Nerve Ablation

Posterior nasal nerve (PNN) ablation is a minimally invasive treatment option for patients with chronic rhinitis. Recent evidence shows that parasympathetic innervation of the nasal cavity is more extensive and there are many fibers posterior to the lateral attachment of the middle turbinate. This article describes a modified ablative technique that targets the extensive innervation of the posterior nasal nerves.
