Abstract

Accessory maxillary ostium can be a result of maxillary sinus inflammation or congenital I anatomic variation. Endoscopic sinus surgeons should be aware of the more anatomical variations I in maxillary ostia to perform the surgery effectively and prevent any reinfection or complications to I the orbit or nasolacrimal duct. Additionally, consciousness of its presence can be taken advantage I of in providing maxillary ventilation if the primary maxillary ostium is blocked. The aim of the study was to evaluate the occurrences of Accessory Maxillary Ostium among the I Mongoloid race in Malaysia. Volumetric CBCT scans of 320 maxillary sinuses from of 160 patients I (1:1 sex ratio) consisting of Malays and Chinese (1:1 ethnic ratio) were retrieved from Oral and I Maxillofacial Imaging Division in a Faculty of Dentistry facility. Image analysis was performed using I the i-CAT Vision Software, employing the multiplanar reconstruction window in which coronal, axial I and sagittal planes were visualized in 0.3 mm intervals. AMO was observed in 44.1 of the total I sinuses studied. The occurrences of AMO in this study could be a useful predictive estimation of I the incidence of maxillary sinusitis in the Malay and Chinese in Malaysia. © 2021. All Rights Reserved.
