The maxillary ostium or maxillary hiatus is an opening that forms the drainage channel of the maxillary sinus and is also one of the components of the ostiomeatal unit. It is located posteriorly and medially near the roof of the maxillary sinus measuring approximately 2-4 mm. It drains into the posterior aspect of the hiatus semilunaris into the middle meatus of the nasal cavity.
