The maxillary sinus is bordered by three main walls:
- The roof – is a thin bony plate shared with the inferior wall of the orbit
- The floor – is composed by the alveolar process of the maxilla. It hosts a couple of elevations formed by the roots of the maxillary teeth. This can be a potential pathway for infection of the sinus, mainly during a complicated dentist procedure.
- The base – makes the inferior portion of the lateral wall of the nasal cavity
