Segmental unilateral transpalatal distraction in cleft patients.

Patients with unilateral cleft lip and palate (UCLP) can present with an asymmetric transversal deficiency caused by collapse of the lateral maxillary segment at the cleft side. The surgical technique and orthodontic implications of segmental unilateral transpalatal distraction (TPD) after a posterior maxillary subapical osteotomy using the transpalatal distractor (TPD(R)) are described. The differences between unilateral posterior surgical-assisted rapid palatal expansion (SA-RPE) and segmental unilateral TPD are discussed.

Comparative cephalometric study of 10-year-old patients with complete unilateral cleft lip and palate. A cross-sectional study of the Hanover concept.

Patients And 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.
