What it can show

Whether the vocal cords move normally, and any lesions, nodules, polyps, inflammation or growths.

What it cannot show

Does not assess lesions deep to the mucosa or neck nodes — that needs imaging.

This is the half people skip. A normal result answers one question, not every question.

Tell the staff before you start

Recurrent nosebleeds · blood thinners · local anaesthetic allergy.

Also bring the full list of every medicine and supplement you take. Things bought without a prescription belong on that list too.
