Mandible Axiolateral and Oblique Axiolateral

• Mandibular body in axial perspective.
• Mandibular angle and ascending ramus.
• TMJ region and condyle in projected area.
• Lateral aspect of mandible without foreshortening.
• 1 inch region beyond lateral border of angle.
• Body of mandible and alveolar process.

• Verify patient identity.
• Remove glasses, earrings, dentures, hairpins.
• Position patient upright or prone in true lateral position.
• For oblique variant: rotate head 30 degrees from true lateral.
• Mid-sagittal plane parallel to IR (or at 30-degree angle for oblique).
• Suspend respiration during exposure.

Mandibular angle region. Head rotated 30° from true lateral.

CR angled 25° cephalad, entering through the mandibular region opposite the side of interest.

Notes

CR angle 25 degrees. Head rotation 30 degrees for oblique variant.

• 1 inch beyond lateral mandibular area visualized.
• TMJ articulation or mandibular angle clearly outlined.
• Body of mandible visualized in axial projection.
• Ramus and angle demonstrated without foreshortening.
• Minimal overlap of mandible and surrounding facial bones.
• Detail of mandibular structure at region of interest.

1. 1 CR not angled 25 degrees: foreshortening of targeted region.
2. 2 Head rotation incorrect: off-center projection of mandible.
3. 3 Rotation: mandibular body and angle not clearly visualized.
4. 4 Tilt: asymmetrical appearance of mandibular region.
5. 5 CR not horizontal: anatomic distortion.

• Mandibular angle fracture assessment.
• TMJ region evaluation with mandibular body.
• Specific mandibular region trauma.
• Evaluation of mandibular body pathology.
• Pre- or post-operative follow-up of mandibular region.
