Piriform aperture
Script error: No such module "Infobox".Template:Template otherTemplate:Main other The piriform aperture, pyriform aperture, or anterior nasal aperture is a pear-shaped opening in the human skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and the greater and lesser alar cartilages of the nose.[1]
It is bounded above by the inferior borders of the nasal bones; laterally by the thin, sharp margins which separate the anterior from the nasal surfaces of the maxilla; and below by the same borders, where they curve medialward to join each other at the anterior nasal spine.[1]
