BACKGROUND: The etiology and the effects of the maxillary accessory ostium (MAO) are not well understood. The aim of this study is to investigate the association between septal deviation (SD) and the presence of an MAO. METHODS: Paranasal computed tomography (CT) scans of 1104 adult patients were studied retrospectively. Patients with chronic sinusitis, acute sinusitis, nasal polyposis, allergic rhinitis, paranasal sinus tumors, septal perforation, and unilateral or bilateral maxillary sinus hypoplasia/aplasia, as well as patients who had previously had nasal surgery or a history of nasal trauma, were not included in the study. Eight-hundred and seven patients were found to meet the criteria and were included in the study. CT scans were examined to note the presence of SD and MAO and the side of both diseases. RESULTS: A total of 807 patients were evaluated. SD and MAO were detected in 572 (70.9%) and 299 (37.1%) patients, respectively. A statistically significant relationship was found between the presence of SD and MAO, regardless of side of the disease (p = 0.002). The side of MAO showed a significant correlation with the direction of SD (p < 0.001). CONCLUSION: Our results revealed a link between SD and MAO. This relationship was correlated with the side of occurrence of the disease.
