Comparison of serum zinc levels between patients with sinonasal neutrophilic and eosinophilic inflammatory polyposis and healthy individuals.

Objectives: Some changes in nasal mucus and paranasal sinuses may occur due to zinc deficiency, which can cause chronic rhinosinusitis with nasal polyps (CRSwNP). The current study was designed to compare the serum zinc concentration between patients with chronic rhinosinusitis complicated with eosinophilic or neutrophilic nasal polyps and a control group.

Methods: A total of 105 patients participated in the study.
