**Note 3:** The bones of the lateral wall of the nasal cavity include the maxilla, the perpendicular plate of the palatine bone, the medial pterygoid plate, the labyrinth and inferior concha of the ethmoid. The roof of the nasal cavity is formed by the nasal bone. The floor of the nasal cavity, which forms the roof of the mouth, is composed of the bones of the hard palate: the horizontal plate of the palatine bone posteriorly and the palatine process of the maxilla anteriorly.
**Note 4:** Involvement of or extension to bone includes any type of tumor extension to the bone, such as erosion, invasion, extension, penetration, or destruction.
**Note 5:** "Bony invasion" does not include extension to palate, cribriform plate, or pterygoid plates. Extension to these structures is coded separately.
**Note 6:** "Bony invasion" does include involvement of perpendicular plate of ethmoid bone or ethmoid air cells.
**Note 7:** Code 2 for base of skull, NOS when there is no information available for more specific bony structures in the skull.
**Note 8:** Minimal extension to anterior cranial fossa implies tumor pushing through the cribriform plate, but without invasion of the dura or brain.
