Regarding calcification of laryngeal cartilages, which statement is correct?
- A The epiglottis calcifies first because it is a hyaline cartilage
- B All laryngeal cartilages are elastic cartilage and therefore do not calcify
- C The thyroid cartilage calcifies first, followed by the cricoid and then arytenoid ✓
- D The cricoid cartilage calcifies first, followed by the arytenoid and then thyroid
Correct answer: C. The thyroid cartilage calcifies first, followed by the cricoid and then arytenoid
Explanation
The thyroid, cricoid, and arytenoid cartilages are hyaline cartilages that undergo calcification (and sometimes ossification) with age, beginning around the third decade. The thyroid cartilage typically calcifies first, followed by the cricoid and then the arytenoid. The epiglottis, lingual cartilage, and corniculate/cuneiform cartilages are elastic cartilage and do not calcify. Calcification patterns are visible on CT imaging.
