Oedema of larynx. Artwork of a vertical (coronal) section through a larynx, showing oedema (swelling caused by fluid accumulation). The swelling here is just above centre, in the mucous tissue of the epiglottis, just above the vocal folds (vocal cords). Swelling such as this is known as laryngeal oedema and oedema glottidis. If the swelling increases, it could block the airway and can be fatal. As well as the soft tissue (red and yellow), throat cartilage (blue) is also shown. For an axial view of this condition, and a healthy larynx, see image C016/6529.
