Summary
Three-dimensional CT imaging revealed coronoid process hyperplasia impinging on malar bone exostosis. This advanced imaging aids surgical planning for limited jaw opening, identifying subtle bone changes.
Area of Science:
- Dentistry
- Radiology
- Orthopedic Surgery
Background:
- Coronoid process hyperplasia can cause jaw limitation.
- Conventional radiography may not fully reveal the condition.
Observation:
- Three-dimensional CT imaging was used to examine three cases of coronoid process hyperplasia.
- The technique visualized impingement between the enlarged coronoid process and malar bone exostosis.
Findings:
- 3D CT identified impingement and a unique malar bone concavity not seen with other methods.
- Malar exostosis on conventional radiographs may indicate coronoid process hyperplasia.
Implications:
- 3D CT imaging is valuable for surgical planning in coronoid process hyperplasia.
- Early detection is possible with conventional radiographs if malar exostosis is present.
