    Imaging of Primary

    • T1 / T2
      • Minority require imaging
      • CT / MRI to exclude thyroid cartilage or prevertebral tissue invasion if tumour immobile at examination under anaesthesia
    • T3/4
      • CT / MRI rarely helpful if total laryngectomy planned
      • If total laryngectomy planned: consider CT / MRI if concern about extrapharyngeal extension or prevertebral tissue invasion
      • If chemoradiation considered
        • CT / MRI recommended
        • Thyroid cartilage invasion
        • Staging of cervical nodes

    Cervical metastases

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

    Distant metastases:  CXR / CT chest: T2 – 4 cancers

    Synchronous primary: CXR / CT chest
