Aim: The aim of the study was to assess the prevalence of anatomical variations in the sinonasal complex using computed tomography (CT) in patients with non-odontogenic sinusitis.
Methods: This observational and retrospective study involved the analysis of 860 multislice CT scans prescribed for sinusitis evaluation. Non-odontogenic sinusitis was characterized by the presence of sinus mucosal thickening exceeding 2 millimeters and the absence of dental changes in the region. Subsequently, sinonasal complex variations were evaluated, and a descriptive analysis was conducted. Subsequently, 33 CT scans with non-odontogenic sinusopathy were analyzed, and the sinonasal complex was evaluated for the presence of the following anatomical variations: deviation of the nasal septum associated with a bony spur, bullous middle concha, unilateral hypoplasia of the maxillary sinus, among others.
Results: Anatomical variations were observed in 87.9% of cases, with 15 males (46.0%) and 18 female (54.0%), distributed among patients aged 41-60 years (45.5%). The most frequent anatomical variation was the bullous middle concha (37.9%), followed by septations in the maxillary sinus (10.3%) and enlarged frontal sinus (13.8%).
Conclusion: A considerable incidence of anatomical variations associated with non-odontogenic sinusitis was observed, with evidence of a bullous middle concha.
