Tumours of the hypopharynx
The definition of these sites is shown in Table 13.1. The larynx projects into the hypopharynx from the front so that grooves, known as the pyriform fossae, are formed on either side. These are shallow above and are separated from the valleculae by the pharyngoepiglottic folds. Lower down, the pyriform fossae become deeper. The upper shallow part of the pyriform fossa is bounded laterally by th...
