Doctors also use a cancer's stage when talking about survival statistics. The earliest stage of nasal cavity and paranasal sinus cancers is stage 0, also known as carcinoma in situ (CIS). The other stages range from I (1) through IV (4). Some stages are split further, using capital letters (A, B, etc.).

Maxillary Sinus. Maxillary sinuses, the largest of the paranasal sinuses, are pyramid-shaped cavities located in the maxillae. The base of the maxillary sinus forms the inferior part of the lateral wall of the nasal cavity. The roof of the maxillary sinus is formed by the floor of the orbit, which contains the infraorbital canal, and the floor.
