Aim: Accessory maxillary ostium may have an embryologic association with the variations around the paranasal sinuses. This study aimed to investigate the cross-sectional and developmental associations of the accessory maxillary ostium with various anatomical variations around the ostio-meatal complex and maxillary sinus in children.
Materials and Methods: Medical records and paranasal computed tomography sections of 457 patients aged 3–17 years were reviewed retrospectively. The study group consisted of 184 patients with accessory maxillary ostium (AMO group), and the control group consisted of 273 patients without accessory ostium. The frequencies of the anatomic variations around the ostio-meatal complex and maxillary sinus pathologies were compared between groups.
Results: Compared with the control group, the AMO group had a higher frequency of anteverted middle turbinate (p=0.036, X2= 4.405), mucus retention cyst (p=0.007, X2= 7.179), Haller cell (p=0.003, X2= 8.875), and maxillary sinus septa (p=0.042, X2= 4.14).
Conclusion: Accessory maxillary ostium was significantly associated with the presence of anteverted middle turbinate, mucus retention cyst, Haller cell, and maxillary sinus septa in children.
Keywords: Accessory ostium, maxillary sinus, ostio-meatal complex, paranasal sinus tomography, pediatric sinus
