Study Notes
Maxilla Overview
- The maxilla, or upper jaw, is comprised of two maxillary bones joined at the midline.
- It forms a significant part of the upper facial skeleton and contributes to the structure of the face, including the infratemporal region, orbital floor, lateral wall of the nasal cavity, and roof of the oral cavity.
Maxillary Features
- Contains four processes and four surfaces.
- Hosts foramina for neurovascular structures.
- Formulates the alveolar process, which supports the maxillary teeth and contributes to the upper dental arch.
Articulations of the Maxilla
- Articulates with multiple bones including:
- Nasal bone
- Frontal bone
- Zygomatic bone
- Vomer
- Palatine bone
- Internal articulations include lacrimal bone, ethmoid bone, and inferior concha.
- Maxillary teeth articulate with the mandible through the temporomandibular joint.
Maxillary Processes
- Alveolar Process: Forms sockets for maxillary teeth.
- Zygomatic Process: Lateral aspect contributes to forming the zygomatic arch via articulation with the zygoma.
- Frontal Process: Projects upward to connect with the frontal, nasal, and lacrimal bones.
- Palatine Process: A horizontal shelf forming the roof of the oral cavity and floor of the nasal cavity.
Maxillary Surfaces
- Facial Surface: Forms the upper face.
- Nasal Surface: Constructs the lateral wall of the nasal cavity.
- Orbital Surface: Creates the floor of the orbit.
- Infratemporal Surface: Contributes to the wall of the infratemporal region.
Maxillary Sinus
- A large air-filled space present in each maxillary bone.
- Extends laterally to the zygomatic process, posteriorly to the infratemporal wall, and inferiorly towards the alveolar process.
- Clinically significant as infections may present as toothaches in the upper molars.
Cleft Lip and Cleft Palate
- Cleft Lip: Can range from small notches to wide gaps affecting one or both sides of the lip.
- Cleft Palate: May present as an opening in the back of the mouth or a split running to the front; sometimes hidden by mucosal lining.
- Both conditions are common facial birth defects, affecting approximately 1 in every 700 births in the UK.
- Surgical interventions produce good aesthetic and functional outcomes.
Challenges Associated with Cleft Palate
- Dental problems due to misaligned teeth.
- Feeding difficulties and potential hearing issues.
- Speech problems that may require therapeutic intervention.
