Conclusion
In conclusion, this study found that the overall prevalence of paranasal
sinusitis in Chinese adults aged 35–75 years is 15.4 %. The
major
risk factors for paranasal sinusitis include age, sex, and smoking. In
non-smokers, the prevalence of paranasal sinusitis increases with age,
while in smokers, sinusitis more often involves the anterior nasal
sinuses. These results may facilitate the understanding of the
epidemiology of paranasal sinusitis detected by MRI and prove valuable
in the prevention and treatment of paranasal sinusitis.
