The incidence of an accessory maxillary ostium (AMO) varies depending on the population and the method used to detect it. In general, AMOs are considered to be relatively rare, with an incidence of 1-2% in the general population. However, the incidence may be higher in certain groups, such as patients with chronic sinusitis or polyposis. The degree of association between Rhinosinusitis and presence of accessory maxillary ostium is still a point of debate. It can vary depending on the population being studied and the method of diagnosis. Some studies have found a prevalence of accessory maxillary ostium varies from 2-25%, while others have reported rates as high as 44%. Factors such as genetics, race, and sex may also play a role in the development of an accessory maxillary ostium. It is not clear whether maxillary accessory ostia are congenital or acquired. Some studies claim that they develop following maxillary sinusitis. Aim and Objective:To determine the incidence of accessory maxillary ostia in patients of rhinosinusitis. To determine the correlation of accessory maxillary ostia and rhinosinusitis.Methods: A total of 100 consecutive diagnosed patients of Chronic Rhinosinusitis attending E.N.T OPD were enrolled in the study and the correlation between accessory maxillary ostium and rhinosinusitis is assessed.Results: Most common presenting symptoms were nasal obstruction (83%) while anosmia (9%) was the least common. The other complaints were repeated rhinitis (79%), post nasal drip (75%), nasal discharge (73%), headaches (69%) and facial pain (41). 20% of those patients with chronic rhinosinusitis (CRS) had an accessory maxillary ostium (p < 0.001). Conclusion:To conclude, from our study we can say that patients with chronic rhinosinusitis (Both CRSwNP and CRSsNP) had higher incidence of an accessory maxillary ostium. Presence of accessory maxillary ostium (AMO) requires it's meticulous removal.

Purposes: The aim of this study is to evaluate the prevalence of accessory maxillary ostium (AMO) and its association with age, gender, sinus variation, pathological formations, status of dentition and tooth endodontic and periodontal status using cone-beam computed tomography (CBCT).Methods : The study examined archived CBCT images of 390 patients at least 18 years old (232 females and 158 males) representing 790 regions of interest. The mean age of the female patients was 46.35 and that of the males was 48.62. All the CBCT images analyzed with sagittal, coronal and axial sections. The data were assessed using IBM SPSS 22. Significance was evaluated at the p <0.05 level. Results: The study observed that while the prevalence of primary maxillary ostium (PMO) on the right side was 94.9% and on the left side was 94.6% (for a total of 94.7%), the prevalence of accessory ostium on the right side was 33.1% and on the left was 35.4% (34.2% in total).Conclusions: There was no significant difference in AMO prevalence related to age, presence of mucosal thickness, mucus retention cysts, maxillary sinusitis, sinonasal variation, status of dentition or periodontal status of posterior maxilla. However there was a relationship between AMO and both gender and endodontic status.

Introduction:The accessory maxillary ostium (AMO) is an anatomical variation that can be associated with the pathologies of the maxillary sinus, sinonasal variations, and dentition status. Objectives: The aim of this study was to evaluate the prevalence of AMO and its association with age, sex, sinus variation, pathological formations, the status of dentition, and tooth endodontic and periodontal status using cone-beam computed tomography (CBCT). Material and methods:The retrospective analysis of CBCT scans from 390 patients over the age of 18 years (232 female and 158 male) was carried out in this study. All the CBCT images were analysed with sagittal, coronal, and axial sections. The intra-class correlation coefficient (ICC) was used to test intra-observer agreement. P-values of 0.05 were considered statistically significant at a 95% confidence interval (95% CI).Results: In the present study, 780 sinuses from a total of 390 CBCT scans were analysed. The prevalence of AMO was 33.1% on the right side and 35.4% on the left. There was no statistically significant relationship between the presence of AMO and pathological formation in all individuals (p > 0.05). No statistically significant difference was observed between the prevalence of AMO and sinonasal variations. Conclusions: There was no significant difference in AMO prevalence related to age, presence of mucosal thickness, mucus retention cysts, maxillary sinusitis, sinonasal variation, the status of dentition, and the periodontal status of posterior maxilla. However, there was a relationship between AMO and both sex and endodontic status.
