Mandibular morphology in complete unilateral cleft lip and palate.

Objective: The purpose of this study was to evaluate and compare mandibular morphology and spatial position in children with complete unilateral cleft lip and palate (UCLP) treated at two different cleft centers (Hannover and Brussels) following different surgical treatment protocols.

Patients: A total of 62 Caucasian children (40 boys, 22 girls) with nonsyndromic complete unilateral cleft lip and palate (UCLP) were evaluated by means of conventional cephalometric analysis at approximately the age of 10 years. Data of both cleft groups were compared with a control, noncleft group (n = 40) matched according to age and sex.

Reliability and validity of a modified lateral cephalometric analysis for evaluation of craniofacial morphology and growth in patients with clefts.

In previous intercenter studies on craniofacial morphology in patients with unilateral cleft lip and palate, probable surgical-induced changes in mandibular morphology and spatial position related to posterior vertical maxillary morphology were identified by our group. These changes could not be detected in other cephalometric cleft studies because posterior vertical maxillary height and vertical mandibular ramus length were not measured simultaneously. This study presents a modified digital lateral cephalometric hard and soft tissue analysis (Onyx Ceph software, version 2.

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.
