The anatomy of the upper aerodigestive tract is clearly identified in lateral cervical plain radiographs. Note the silhouette of the hard and soft palate, the tongue, including the tongue base, and the vallecula, and the epiglottis; the situation of the glottis can be easily estimated. The reference for the measurement of the distances is a 10 cents of eurocoin applied with adhesive tape to the midline of the neck (a constant size in any possible position: 20 mm), and there is a timer in the top right corner counting by the hundredth of a second.
