The septodorsal cartilage (quadrilateral cartilage) of the nose articulates posteroinferiorly with the:

• A Maxillary crest alone
• B Frontal bone and nasal bones
• C Inferior turbinate and palatine bone
• D Perpendicular plate of the ethmoid and vomer ✓

Explanation

The quadrilateral (septal) cartilage articulates: superiorly with the perpendicular plate of the ethmoid and nasal bones, posteroinferiorly with the vomer and palatine crest (and maxillary crest), and anteroinferiorly with the anterior nasal spine and premaxilla. Understanding these articulations is essential for septoplasty, as septal deviations arise at these junctions and must be addressed at the correct articulation point to achieve correction.
