Imaging for Glottic Cancer

Imaging is only required if it may change management

Imaging of Primary

T1 / T2
- Minority require imaging
- Consider for anterior commissure tumours if concern about thyroid cartilage invasion

T3/4
- CT / MRI rarely helpful if total laryngectomy planned
- CT / MRI recommended if chemoradiation or partial laryngectomy considered
  - Thyroid cartilage
  - Paraglottic extension
  - Staging of cervical nodes

If primary radiation considered: Ultrasound, CT or MRI of larynx to exclude thyroid cartilage invasion

Cervical metastases

N0 neck: No need to image if elective neck dissection planned or for T1/2 glottic cancers
N+ neck: Image (U/S or CT) if concern about resectability

Distant metastases: CXR / CT chest: T3/4 glottic cancers

Synchronous primary: CXR / CT chest
