Incidence of Accessory Maxillary Ostia in Patients of Rhinosinusitis: A Clinical Study

Abstract

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.
