摘要

<strong>Objective:</strong> This case-control study aimed to detect the presence of fungal biofilms in cases of fungal sinusitis, trying to find its role in recurrence of fungal sinus infection and resistance to medical treatment. <strong>Patients and Methods:</strong> This study was conducted at Ain-Shams University from June-2017 to June-2018 upon 20 patients as the fungal cases are not much in Egypt. All patients were subjected to functional endoscopic sinus surgery and taking specimens. Examination of specimens by scanning electron microscope was made. <strong>Results:</strong> The prevalence of fungal biofilms was 7 (70%) in cases and 0 (0%) in controls (p-value = 0.001). There is higher risk of fungal biofilms in cases of fungal sinusitis, the odds of biofilms is higher in the study group 2.33 than in the control group 0. The lower is the invasiveness, the higher is the fungal biofilms (OR = 0.94, 95% CI 0.46 - 4.05). Also, the analysis showed that the lower is the recurrence the lower is the fungal biofilms (OR = 2.25, 95% CI 0.15 - 7.93). <strong>Conclusion:</strong> This study showed the presence of fungal biofilms in different cases of fungal sinusitis whether primary or recurrent, also whether invasive or non-invasive. Studies with large sample size are recommended to get a strong evidence.
