Abstract

<abstract xml:lang="en" abstract-type="author" id="abs0010"> <title id="sectitle0010">Abstract</title> <sec> <title id="sectitle0015">Background</title> <p id="abspara0010">The authors have recently reported on the use of an internal maxillary distraction device. In this study, we report on the hard and soft tissue movements achieved with this intraoral distraction device, and the stability changes after distraction osteogenesis for maxillary hypoplasia in patients with cleft lip and palate.</p> </sec> <sec> <title id="sectitle0020">Methods</title> <p id="abspara0015">Ten male patients with severe hypoplasia of the maxilla, with complete uni- or bilateral cleft lip and palate were included. The mean age of the patients at the time of operation was 11.91 years (±3.41). To evaluate the distraction process and stability, superimpositions on the preoperative lateral cephalograms were performed. The mean follow-up (FU) was 15.42 months (±3.94).</p> </sec> <sec> <title id="sectitle0025">Results</title> <p id="abspara0020">Cephalometric measurements at all of the maxillary hard and soft tissue points improved significantly. Maxillary point A was advanced by 8.25 mm (±3.17; <italic>P</italic> < 0.001). After distraction soft tissue point A′ had advanced 7.10 mm (±2.69; <italic>P</italic> < 0.001). The soft tissue to hard tissue ratio at point A was 0.86:1 after distraction. Maxillary horizontal relapse at point A was 14.1% at FU. Vertical relapse was not significant.</p> </sec> <sec> <title id="sectitle0030">Conclusion</title> <p id="abspara0025">This rigid intraoral distraction device can be successfully used in the correction of severe maxillary hypoplasia. The marked aesthetic improvement and low psychological encumbrance make this device viable for the treatment of cleft-related hypoplasia of the maxilla.</p> </sec> </abstract>
