Soluble Guanylate Cyclase Dysfunction and Nitric Oxide Pathway in Chronic Rhinosinusitis With Nasal Polyps: Predictive Markers for Postoperative Recurrence.

Background: Elevated nitric oxide (NO) levels have been linked to a heightened risk of recurrence in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). However, the precise influence of NO on CRSwNP recurrence remains unclear.

Objective: This study seeks to elucidate the relationship between NO levels and the risk of CRSwNP recurrence.
