Prevalence of Positive Fungal Cultures in Patients with Chronic Sinusitis undergoing Functional Endoscopic Sinus Surgery in Yasuj, Iran

Aims: Sinusitis is the inflammation of the nasal cavity, and Paranasal sinuses occur by pathogen agents such as bacteria, viruses, fungi, or other allergens. This study was aimed to determine the prevalence of positive fungal cultures in patients with chronic sinusitis undergoing functional endoscopic sinus surgery.  Materials & Methods: This experimental study was carried out on ۶۰ patients with chronic sinusitis in ۲۰۱۹. After anesthesia in the operating room, the ENT specialist evacuated the sinuses of patients with chronic sinusitis undergoing sinus endoscopic surgery. After sampling of evacuated sinus tissue of eligible patients and transfer to mycology laboratory, fungal elements were identified using direct smear and culture of the sample on sub-dextrose agar medium. The patient's profiles were recorded. Data were analyzed using SPSS ۲۱ software by the descriptive statistic. Findings: ۳۶ of selected patients with chronic sinusitis were male (۶۰%), and ۲۴ were female (۴۰%) with a mean age of ۳۸.۴±۱۱.۵ years. Two Candida parapsilosis (۳.۳%), one Aspergillus flavus (۱.۷%), and one Aspergillus niger (۱.۷%) were detected. Therefore, the prevalence of positive fungal cultures in patients with chronic sinusitis undergoing endoscopic sinus surgery was ۶.۷% in Yasuj, southwest of Iran, in ۲۰۱۹. Conclusion: The prevalence of fungal sinusitis is low in patients with chronic sinusitis in Yasuj due to the location of Yasuj in a mountainous region with a cold and dry climate.
