[Text about imaging choices]
There are several classifications for JNAs based on imaging findings.
| Stage | Description |
|---|---|
| I | Tumor confined to the nasopharynx |
| II | Tumor extension into the nasal cavity, sphenoid sinus, or both |
| III | Tumor extension into one or more of the following: antrum, ethmoid sinus, pterygomaxillary or infratemporal fossa, orbit, or cheek |
| IV | Intracranial extension |
The UPMC classification system is slightly different from the Chandler system:
| Stage | Description |
|---|---|
| I | Tumor limited to the nasopharynx and nasal cavity. Bone destruction negligible or limited to the sphenopalatine foramen. |
| II | |
| IIIa | |
| IIIb | Intracranial extension |
| IVa | Intracranial extension |
| IVb | Intracranial extension |
