Abstract
OBJECTIVE: To propose a skeletal maturity assessment method by developing a statistical regression analysis model through the integration of lateral and axial images of cervical vertebrae of cleft lip and palate (CLP) patients obtained through cone beam computed tomography (CBCT).
METHODS: Forty-nine patients with CLP (28 females, 21 males; age range, 4-16 years) who had CBCT and hand-wrist radiographic data were selected. With the landmarks' coordinates from lateral and axial images of cervical vertebrae, Procrustes analysis and principal components analysis yielded principal component (PC) scores of each cervical vertebra, with the centroid size as the size factor. The meaningful PC scores were used for multiple regression models.
RESULTS: When both axial cervical vertebrae and lateral cervical vertebrae were used together, there was a 6.7% increase in SML (Sempé maturation level) explanatory power for skeletal maturation estimation for females and an 11.4% increase for males compared to when only chronological age was used.
CONCLUSION: This study improved estimating regression models using statistical shape analysis with lateral and axial cervical vertebral shapes. The obtained models had improved explanatory power for skeletal maturity estimation than previous studies with healthy people.
