Objective: Measure lower lip thickness and eversion in patients with cleft lip and palate (CLP) and maxillary hypoplasia. The specific aims were to (1) compare lower lip thickness/eversion in patients with CLP to noncleft controls with maxillary hypoplasia, (2) determine differences between patients with unilateral CLP (UCLP) and bilateral CLP (BCLP), and (3) document changes in the lower lip that occur with Le Fort I advancement.

Design: Retrospective case-control study.

Objective: To examine the impact of dentofacial infant orthopedic treatment (DFIO) on facial growth in preadolescent children with unilateral complete cleft lip and palate (UCCLP) and bilateral complete cleft lip and palate (BCCLP).

Methods: This is a retrospective study of patients with UCCLP and BCCLP treated at a single center. The treatment group had DFIO, and the control group did not have DFIO.

Objective: Characterize mandibular morphology in patients with syndromic craniosynostosis and document changes in mandibular position following midfacial advancement using distraction osteogenesis (DO).

Design: Retrospective chart review and analysis of cephalometric radiographs.

Setting: Tertiary care center.

Children with unilateral cleft lip and palate (UCLP) suffer from negative public perceptions. A better treatment strategy should be established to help them live an ordinary life with improved perceptions. To do that, it is important to understand the relationship between physical facial features and perceptual judgment.

Purpose: Gradual midfacial advancement, applying the principle of distraction osteogenesis, reduces the restriction of the soft tissues and results in bony consolidation without need for grafting. The midface can be distracted by either pushing it forward, using semiburied devices, or pulling it forward by a rigid external device. For each method there are inherent technical problems, such as controlling the vector of movement, symmetry of advancement, and differential movement of the upper/lower face.
