Study Notes
Maxilla Overview
- The maxilla consists of two paired maxillary bones forming the upper jaw.
- Central to the upper facial skeleton, it plays a role in facial structure and the formation of various regions including the infratemporal area, orbital floor, and roof of the oral cavity.
Articulations of the Maxilla
- Articulates with several bones including:
- Nasal Bone
- Frontal Bone
- Zygomatic Bone
- Vomer
- Palatine Bone
- Internal articulations involve the Lacrimal Bone, Ethmoid Bone, and Inferior Concha.
- The maxillary teeth connect to the mandible via the Temporomandibular Joint.
Maxillary Processes and Surfaces
- Contains four main processes:
- Alveolar Process: Supports maxillary teeth; forms the upper dental arch.
- Zygomatic Process: Located laterally, supporting the zygomatic arch.
- Frontal Process: Connects with the frontal, nasal, and lacrimal bones.
- Palatine Process: Horizontal structure forming the roof of the oral cavity and the floor of the nasal cavity.
- Features four surfaces:
- Facial Surface: Forms the upper face.
- Nasal Surface: Contributes to the lateral wall of the nasal cavity.
- Orbital Surface: Forms the floor of the orbit.
- Infratemporal Surface: Forms the wall of the infratemporal region.
Maxillary Sinus
- A large air space located in each maxilla, extending in various directions and closely related to the roots of maxillary molars.
Abnormalities: Cleft Lip and Palate
- Cleft Palate: A developmental condition where the two halves of the palate fail to fuse; often associated with cleft lip. Occurs in about 1 in 700 births in the UK.
- Cleft Lip: Can range from a small notch to an extensive gap reaching the nose. It may affect one or both sides of the lip.
- Surgical interventions can yield excellent aesthetic and functional outcomes, usually starting in the first few months of life.
- Associated challenges include feeding difficulties, hearing issues, dental anomalies, and speech problems.
