The hypopharynx communicates superiorly with the oropharynx and inferiorly with the oesophagus, and is located posteriorly to the larynx. The superior border is an imaginary line from the superior border of the hyoid bone (or floor of the valleculla). The inferior boundary is anteriorly formed by the aryepiglottic folds that separate the hypopharynx from the larynx and posteriorly is the level of the inferior border of the cricoid cartilage and the apex of one piriform sinus to the other.
