Definition: Calcification of the triticeal cartilage, located in the lateral thyrohyoid ligament, commonly visible on panoramic radiographs.
Radiographic Features:
- Location: Inferior to the hyoid bone
- Edge: Well-defined with a smooth outline
- Shape: Round, ovoid, or ‘kidney bean’ shaped
- Internal structure: Radiopaque border with a radiolucent center
- Other: May be unilateral or bilateral
- Number: Single per side
Key points:
- Normal anatomical variant, not pathological
- More commonly visible in older individuals
- Can be mistaken for carotid artery calcifications
- Typically smaller and more well-defined than atherosclerotic plaques
Clinical significance:
- No clinical significance or treatment required
- Important to differentiate from pathological calcifications (e.g., carotid artery atherosclerosis)
- Awareness prevents unnecessary referrals or interventions
- Helps in accurate interpretation of panoramic radiographs
Note: Proper identification of triticeal cartilage calcification is crucial to avoid misdiagnosis as carotid artery calcifications. Consider location, shape, and border characteristics for accurate differentiation.
