OBJECTIVES The objective of this study is to analyze the hard and soft-tissue profile changes as well as the upper airway changes after distraction osteogenesis (DO) using rigid external distraction device in adult cleft lip and palate (CLP) patients. The study also evaluates the stability of the surgical result. MATERIALS AND METHODS Three lateral cephalometric radiographs were taken: Predis...

In a single-stage procedure, a maximal advancement of 10 to 12 mm can be achieved in noncleft patients after good mobilization of the separated upper jaw complex. The greater the distance through which the upper jaw is operatively advanced, however, the greater the resulting skeletal relapse.1 The blood vessels supplying the area and the soft tissue attached to them are elastic and together the...

Previous studies have indicated that an injured condyle during adolescence is a causative factor for reduced mandibular growth and resulting asymmetry of the mandible. The aim of this study was to examine the nature of mandibular growth after unilateral condylectomy and to elucidate the effects of mandibular advancement. Sixty growing mice were subjected to unilateral condylectomy, and then one...
