Study Notes
Maxilla
- The maxilla is the upper jaw, made up of two maxillary bones joined together.
- It forms the upper face, infratemporal region, orbital floor, lateral wall of the nasal cavity, and roof of the oral cavity.
- The maxilla articulates with the following bones:
- Nasal bone
- Frontal bone
- Zygomatic bone
- Vomer
- Palatine bone
- Lacrimal bone
- Ethmoid bone
- Inferior concha
- Mandible (via the temporomandibular joint)
Maxillary Processes and Surfaces
-
The maxilla has four processes:
- Alveolar process: holds the maxillary teeth.
- Zygomatic process: contributes to the zygomatic arch.
- Frontal process: articulates with the frontal, nasal, and lacrimal bones.
- Palatine process: forms the roof of the mouth and floor of the nasal cavity.
-
The maxilla has four surfaces:
- Facial: forms the upper face.
- Nasal: forms the lateral wall of the nasal cavity.
- Orbital: forms the floor of the orbit.
- Infratemporal: forms the wall of the infratemporal region.
-
The maxilla contains the maxillary sinus, a large air space that extends to the facial surface, zygomatic process, infratemporal wall, and alveolar process.
Cleft Lip and Palate
- A cleft palate occurs when the two halves of the palate do not fuse properly during development.
- It may be associated with a cleft lip.
- Cleft lip and palate is a common facial birth defect, affecting 1 in 700 babies in the UK.
- Surgery produces excellent aesthetic and functional results.
- Cleft lip and palate can affect feeding, hearing, speech, and dental development.
