Dr Daniel J Bell et al.

Accessory maxillary ostia are a common anatomic variant, and are usually found incidentally on CT scans of the paranasal sinuses. Accessory ostia of the maxillary sinus are common, occurring in up to 40% patients 1. No significant association has been found between the presence of accessory ostia and symptomatic chronic rhinosinusitis or pathological mucosal thickening of the maxillary antra.
