Correlation Between Nasal Anatomical Variants and SNOT-22 in Patients Affected by Odontogenic Sinusitis: A...

Objectives: The aim of this study is to analyze the correlation between the nasal anatomical variants and the clinical and radiological features of odontogenic sinusitis to demonstrate their possible involvement in the genesis of the disease. Methods: This is a retrospective multicentric study of 70 patients with odontogenic sinusitis (OS). Before surgery, all patients performed the classic and mini 22-item Sino-Nasal Outcome Test (SNOT-22 and SNOT-8) and Lund-Mackay Score (LMS). Each nasal anatomical anomaly was collected, including paradoxical middle turbinate (PMT), chonca bullosa (CB), and nasal septal deviation (NSD) on the same side as the sinusitis. Results: The patients presented a significantly higher SNOT-22 and SNOT-8 score only in case of association with NSD and PMT/CB. Logistic regression showed that the variables were significantly associated (p = 0.02 and 0.04). No significant correlation was found between LMS and anatomical variations. Conclusions: This study showed that nasal anatomical variables are correlated with SNOT-22 and SNOT-8. Having a combination of NSD and CB or PMT, on the same side as an OS, is related to a worse quality of life in patients affected by this disease. Regarding the radiological features of OS, no significant correlation was found between LMS and anatomical variations.
