Flashcards
Lateral Cephalometric
Lateral Cephalometric
An X-ray view showing the side profile of the skull for orthodontic analysis, pre/post surgery evaluation, and assessing facial growth, development, and anomalies.
Lateral Oblique
Lateral Oblique
An X-ray view taken at a slight angle, showing the mandibular angle, ramus, and body, useful for detecting fractures and unerupted teeth.
True PA (Postero-anterior)
True PA (Postero-anterior)
An X-ray view where the beam is directed perpendicular to the face, showcasing the mandible, frontal bone, and sinuses. Useful for detecting fractures and lesions.

Study Notes
Extraoral Views
- Lateral Views:
- Cephalometric: Used for orthodontic analysis, pre and post-orthognathic surgery evaluation, and assessing facial growth, development, trauma (e.g., fractures of the cranium and cranial base, and maxillary sinuses), and sella turcica.
- Oblique: Examines the mandibular ramus and body for impacted teeth, fractures, and submandibular salivary gland stones.
- Posteroanterior Views:
- True PA: Used to detect mandibular fractures, and localize and assess pathological lesions. Allows visualization of frontal, ethmoidal, nasal fossae, and orbits in searching for asymmetric growth.
- Sinus View: (additional info)
- Reverse Towne's: (additional info) Assess condylar process, condylar neck, and ramus; detects displacements of sub-condylar and condylar structures, and displays the posterolateral wall of the maxillary sinus.
- Anteroposterior Views:
- True AP: (additional info)
- Towne's: (additional info)
- Submentovertex: (additional info)
Sinus Waters View
- Assessment of all sinuses
- Evaluation of the coronal process for fractures
- Detection of middle facial fractures (orbital floor, nasal septum)
Reverse Towne's View
- Assess the condylar process, neck, and ramus
- Detect sub-condylar and condylar displacement
- Visualize the posterolateral wall of the maxillary sinus
Submentovertex View
- Detection of zygomatic arch fractures
- Visualization of the base of the skull, sphenoid air sinuses, and the lateral wall of the maxillary sinus
- Assessment of the position and orientation of the condyles.
