ENT · Head and neck tumours: narrow band imaging

Sample item

During endoscopy, a surgeon uses filtered blue and green light to highlight abnormal capillary patterns in mucosal lesions. What is this technique?

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

The answer and the reasoning

A. Narrow band imaging

Narrow band imaging uses light at 415 and 540 nm that is absorbed by haemoglobin, showing neovascularity and intraepithelial papillary capillary loops that suggest dysplasia or early cancer. It improves detection of superficial mucosal tumours. It supplements but does not replace biopsy.

Option by option

  • A. Narrow band imaging (correct)

    Correct. It enhances mucosal vascular patterns.

  • B. Toluidine blue test

    Toluidine blue is a vital stain applied to the mucosa.

  • C. Computed tomography

    CT uses X-rays.

  • D. Videostroboscopy

    Videostroboscopy examines vocal fold vibration.
