N2 - Importance: Costal cartilage calcification (CCC) of the cartilage graft, commonly used in reconstruction of nasal/auricular deformities, can cause poor surgical outcome, but structural and quantitative analyses are lacking. Objective: To compare the prevalence, amount, and structural pattern of CCC from individuals by gender and age, as measured by digital contact radiography. Design, Setting, and Participants: This is a cross-sectional cadaveric study (n = 92) of the seventh rib cartilage. CCC prevalence/amount/structural pattern (central [c]/peripheral [p]/diffuse [d]) was analyzed within three age groups: I (<40 years), II (40-70 years), and III (>70 years). Main Outcomes and Measures: Qualitative and quantitative CCC analyses were set in relation to gender/structural pattern/age. Results: CCC prevalence was gender independent (96.7%) and occurred in c/p/d: 12.4%/22.4%/65.2%. Structural CCC pattern differed between age groups (I: 80%; c/p/d: 26.7%/46.6%/6.7%; II: 100%; c/p/d: 18.0%/30.8%/51.2%; III: 100%; p/d: 2.6%/97.4%). The mean CCC amount (9.1%) was gender independent and showed a significant correlation with age (p = 0.001). The mean amount showed a significant difference between the structural pattern [d/p: 3.3 times higher (p = 0.006), d/c: 7.7 times higher (p < 0.001)] and age groups (I/II/III: 6.4/8.5%/10.9%), whereby the amount was higher in groups II (factor: 7.4; p < 0.001) and III (factor: 16.5; p < 0.001) compared with group I. Conclusions: These data show an age-/gender-independent high CCC prevalence in the general population (96.7%). CCC already occurred in young donors (<40 years) with a not negligible amount (6.4%). CCC increased with age and structural analysis showed a gender-/age-specific pattern, whereby males were prone to peripheral/females to central CCC. Diffuse CCC was observed as an age-independent sign for high CCC levels.
