Body of maxilla

The body of the maxilla is somewhat pyramidal in shape, and contains a large cavity, the maxillary sinus (antrum of Highmore).

Surfaces

It has four surfaces - an anterior, a posterior or infratemporal, a superior or orbital, and a medial or nasal.

Surfaces	Anterior: fossae (Incisive fossa, Canine fossa) · Infraorbital foramen · Anterior nasal spine Infratemporal: Alveolar canals · Maxillary tuberosity Orbital: Infraorbital groove · Infraorbital canal Nasal: Greater palatine canal

Processes	Zygomatic process Frontal process (Agger nasi, Anterior lacrimal crest) Alveolar process Palatine process (Incisive foramen, Incisive canals, Foramina of Scarpa, Incisive bone, Anterior nasal spine)

Other	Body of maxilla · Maxillary sinus

Fossae	Pterygopalatine fossa · Pterygoid fossa

Plates	Horizontal plate (Posterior nasal spine) · Perpendicular plate (Greater palatine canal, Sphenopalatine foramen, Pyramidal process)

Processes	Orbital · Sphenoidal

Body	external surface (Symphysis menti, Lingual foramen, Mental protuberance, Mental foramen, Mandibular incisive canal) · internal surface (Mental spine, Mylohyoid line, Sublingual fovea, Submandibular fovea) · Alveolar part of mandible

Ramus	Mylohyoid groove (Mandibular canal, Lingula) · Mandibular foramen · Angle Coronoid process · Mandibular notch · Condyloid process · Pterygoid fovea

Minor/
nose

Vomer: Vomer anterior · Synostosis vomerina · Vomer posterior (Wing)
