Larynx

Also called: Adam's apple, laryngeal region, throat voice box, vocal box, voice box

What it means

This is the voice box, the boxy structure you can feel as the bump at the front of the neck (often called the Adam's apple). It sits at the top of the windpipe and houses the vocal cords, the two small bands of tissue that vibrate to make your voice. It has three big jobs: it produces sound for speech, it acts as a gatekeeper that snaps shut when you swallow so food goes down the right tube, and it channels air to and from the lungs. It is made of cartilage, muscle and soft tissue, and is a normal part of everyone's neck.

Why it appears on a CT, MRI or X-ray report

Radiologists name this region to pinpoint findings in the lower throat and upper airway. On neck scans you'll see comments such as 'the larynx is symmetric, with a patent airway' or descriptions of the vocal cords, the cartilage framework, and the surrounding soft tissue. Because both sides should mirror each other, the radiologist often comments on whether the vocal cords move and sit evenly and whether the airway through the box is open. It is commonly assessed for hoarseness, swallowing difficulty, or a neck lump.

What it usually means

A larynx described as 'symmetric', 'patent', or 'unremarkable' is reassuring — the voice box, its airway, and the vocal cords look normal. Mild thickening, swelling, or asymmetry can result from a recent infection, voice strain, acid reflux irritating the area, or a tube having been placed during a previous procedure. The radiologist's chief interest is symmetry and the openness of the airway: matching structures on both sides and a clear air channel are reassuring. A one-sided thickening, a named mass, a vocal cord that sits abnormally, or narrowing of the airway is what prompts a closer look. As with all location words, the description attached to it carries the meaning — 'symmetric' and 'patent airway' are reassuring, while a specific one-sided finding is what would lead a doctor to evaluate further.

When to follow up

The word alone needs no action. Follow up with your doctor if the report describes a mass, marked one-sided thickening, a vocal cord that does not move normally, or narrowing of the airway. Symptoms worth raising include a hoarse or changed voice lasting more than three weeks, persistent difficulty or pain on swallowing, a sensation of something stuck, noisy breathing, or coughing up blood. Sudden severe difficulty breathing is an emergency and needs immediate help, regardless of any imaging wording.

A plain-language way to picture it

Picture a small reed instrument set into the top of a pipe. Air rushing up from the lungs passes over two thin reeds — the vocal cords — making them vibrate to produce your voice, exactly like blowing across a reed. The same instrument also has a lid that flips shut when you swallow, so food slides past instead of falling into the pipe. This word names that whole reed-and-lid device at the front of your neck.
