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.
