ABSTRACT

Introduction: Sinonasal anatomical variants can be a frequent cause of chronic in- fections, so it is important to identify them in daily practice. Objective: To determine the association between the anatomical variants of the osteomeatal complex (OCM) and the development of sinonasal inflammatory pathologies. Materials and methods: Case-control study, a sample of 226 patients is analyzed identifying the anatomical variants of OCM in computed tomography of the paranasal sinuses and their clinical correlation. Results: 51.9% presented imaging findings indicative of sinonasal in- flammatory disease, 19.8% reported symptoms suggestive of sinusitis in the clinical history. The most affected paranasal sinuses were: maxillary (46.9%) and ethmoid (23%). The most frequent anatomical variants were Agger Nasi cells (50.2%) and septal deviation (46.2%). The lateral insertion of the uncinate process (p=0.015) was a statistically significant variable, more frequent on the left side (p=0.018, odds ratio [OR]=4.078, 95% confidence interval [CI]=1.3-12.6). Discussion: The incidence of the most frequent anatomical variants in the literature was confirmed, however not correlated with the clinical findings for the series of patients studied in compari- son with other studies. There is a high relationship between the lateral insertion of the uncinate process and rhinosinusitis findings that are scarcely documented in the medical literature. Conclusion: More studies are required on predictive models in larger population samples and tomographic reading protocols focused on different anatomical variants of the uncinate process
