Role of Microplastics in Chronic Rhinosinusitis Without Nasal Polyps

Objective We aimed to examine the relationship between chronic rhinosinusitis without nasal polyps and microplastics. Methods A total of 80 patients participated in this prospectively planned study. The patients were divided into two groups. Group 1 had 50 patients with chronic rhinosinusitis without nasal polyps, whereas Group 2 had 30 healthy volunteers. The age and gender of the participants were noted. Nose Obstruction Symptom Evaluation questionnaire was applied to the patients. The patients performed nasal lavage with saline. Microplastics were examined in the collected nasal lavage fluids, and their numbers were noted. The groups were compared on these values. Results The mean age was 38.06 ± 14.15 years in the chronic rhinosinusitis group without nasal polyps and 33.60 ± 11.68 years in the control group. There was no significant difference between the groups in terms of age and gender. There was a significant difference in the number of microplastics between the chronic rhinosinusitis group without nasal polyps and the control group ( p < 0.001). Microplastics were detected in all participants. Conclusions We found more microplastics in patients with chronic rhinosinusitis without nasal polyps. According to this result, we can say that there may be a relationship between chronic rhinosinusitis and microplastics. Level of Evidence 3 Laryngoscope , 134:1077–1080, 2024
