ENT · Sinuses: investigation

Sample item

Which investigation is best to evaluate the anatomy and extent of chronic rhinosinusitis before surgery?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Non-contrast CT of the paranasal sinuses (coronal cuts)

Coronal CT displays the ostiomeatal complex, skull base and lamina papyracea, and is the imaging of choice for chronic sinus disease and surgical planning. Plain films are less accurate.

Option by option

  • A. Plain Water's view only

    Plain films have poor sensitivity.

  • B. Non-contrast CT of the paranasal sinuses (coronal cuts) (correct)

    Correct. CT PNS is the investigation of choice.

  • C. Ultrasound of the sinuses

    Ultrasound is unreliable for sinuses.

  • D. MRI of the brain

    MRI is used for tumours or complications.
