Comparative cephalometric study of 10-year-old patients with complete unilateral cleft lip and palate. A cross-sectional study of the Hanover concept.
METHODS
The craniofacial morphology of 10-year-old male (n = 23) and female (n = 13) patients with unilateral cleft lip and palate was evaluated by means of cephalometric analysis. The control group comprised 40 non-orthodontically treated non-cleft patients from the same population (20 boys, 20 girls) with neutroclusion, matched according to age and gender. Furthermore the results of the cephalometric analysis were compared with those of other cleft centers. Primary rehabilitation of all patients was performed according to a uniform concept at Hanover Medical School. All cephalometric radiographs were analyzed according to Ross [26]. This analysis permitted comparison with the results of two different cleft centers covering 107 patients, published by Ross.


RESULTS
In comparison with the control group, both boys and girls with unilateral cleft lip and palate showed a significant retrusion and clockwise rotation of the mandible as well as a decreased vertical midfacial development.
