Olfactory neuroblastoma (staging)

Olfactory neuroblastomas (or esthesioneuroblastomas) are most frequently staged using a system proposed by Kadish et al. in 1976 .

• group a: limited to the nasal cavity
• group b: limited to the nasal cavity and paranasal sinuses
• group c: extends beyond the nasal cavity and paranasal sinuses:
  • base of skull
  • intracranial compartment
  • orbit
  • distant metastatic disease

An additional group d has been proposed by Chao et al. in 2001 .

• group d: cervical nodal metastases

Orbital invasion can also be classified according to the Iannetti classification.
