Abstract: Introduction: Rhinosinusitis is a heterogeneous disease characterized by local inflammation of the upper airways and sinuses. The pathogenesis of chronic rhino sinusitis remains poorly defined. It was recently proposed that Vitamin D deficiency may explain some part of this pattern. The aim of study is to evaluate the effect of vitamin D supplement in patients diagnosed as chronic rhino sinusitis with vitamin D deficiency. Materials and Methods: Prospective study was performed on 57 patients diagnosed as chronic Rhinosinusitis and vitamin D deficiency. Patients received vitamin D3 tablet (1000 IU) daily for one month. Before and after drug intake all patients were asked to fill in a questionnaire in which they rated their overall symptoms. Results: (75.4%) of patients cured from smell disturbance, (22.8%) of patients cured from headache, (21.1%) cured from nasal obstruction and only 7% of patients cured from nasal discharge. (64%) of patients improve (not cured) from nasal obstruction symptoms, (63%) of patients not cure from nasal discharge. Conclusions: Vitamin D supplement shows significant improvement in symptoms of chronic Rhinosinusitis mainly smell disturbance, Vitamin D could be use as adjuvant treatment for Chronic Rhino sinusitis.Abstract: Introduction: Rhinosinusitis is a heterogeneous disease characterized by local inflammation of the upper airways and sinuses.
