BACKGROUND: Both internal and external distraction devices have been used successfully in correcting midface hypoplasia. Although the indication for surgery and the osteotomy techniques may be similar, deciding when to use internal versus external devices has not been studied. The authors studied patient-reported outcomes with FACE-Q and functional surveys for internal and external devices for midface distraction patients. METHODS: Patients who underwent distraction advancement after Le Fort I and Le Fort III were surveyed using the FACE-Q survey and a functional survey...

E Dilaver, S Uckan
The aim of this study was to assess the effect of isolated V-Y plasty on lip lengthening and the treatment of gummy smile. An isolated V-Y plasty was performed on 14 patients with a gummy smile. In each case, measurements of upper lip length and gingival display were recorded from posed-smile photographs taken preoperatively and at 1, 3, and 6 months postoperatively. Gingival display decreased significantly and lip length increased significantly over all intervals investigated. Applying this technique after Le Fort I surgery may be beneficial; however, as with other injection or surgical lip lengthening methods, its stand-alone application should be questioned...

REVIEW
Hak Su Kim, Seong Eun Kim, Hyun Tae Lee
Among the classification of maxillary fracture, the Le Fort classification is the best-known categorization. Le Fort (1901) completed experiments that determined the maxilla areas of structural weakness which he designated as the "lines of weakness". According to these results, there are three basic fracture line patterns (transverse, pyramidal and craniofacial disjunction). A transverse fracture is a Le Fort I fracture that is above the level of the apices of the maxillary teeth section, including the entire alveolar process of the maxilla, vault of the palate and inferior ends of the pterygoid processes in a single block from the upper craniofacial skeleton...
