Study Notes
Maxilla
- The maxilla is a paired bone forming the upper jaw.
- It contributes to the facial skeleton, infratemporal region, orbital floor, nasal cavity wall, and roof of the mouth.
Maxilla Articulations
-
External Articulations:
- Nasal bone
- Frontal bone
- Zygomatic bone
- Vomer
- Palatine bone
-
Internal Articulations:
- Lacrimal bone
- Ethmoid bone
- Inferior concha
Maxillary Processes and Surfaces
-
Processes:
- Alveolar process: Forms sockets for maxillary teeth.
- Zygomatic process: Contributes to the zygomatic arch.
- Frontal process: Projects upward to contact the frontal bone.
- Palatine process: Projects medially to form the roof of the mouth and floor of the nasal cavity.
-
Surfaces:
- Orbital surface: Forms the floor of the orbit.
- Facial surface: Contributes to the upper face.
- Nasal surface: Forms the lateral wall of the nasal cavity.
- Infratemporal surface: Forms the wall of the infratemporal region.
Maxillary Foramina
- Infra-orbital foramen: Opening on the facial surface.
- Incisive foramen: Opening on the palatal surface.
Maxillary Sinus
- Large air space within each maxillary bone.
- Contributes to the paranasal sinuses.
- Closely related to the roots of the maxillary molars.
Cleft Lip and Palate
- Congenital malformations occurring during palate development.
- Cleft lip: Incomplete fusion of the lip.
- Cleft palate: Incomplete fusion of the palate.
- Often occur together.
- May cause difficulties with feeding, hearing, dental development, and speech.
