title: Symphyseal distraction in the context of orthodontic treatment: a series of 35 cases.
abstract: BACKGROUND
  Use of symphyseal distraction osteogenesis to treat a mandibular bone deficit with tooth-jaw discrepancy due to lack of space makes it possible to avoid the risks associated with the techniques usually envisaged (stripping, labioversion of incisors, extractions).
  
  
  METHODS
  This retrospective study presents the symphyseal distraction technique used in the maxillofacial surgery department of Lille University Hospital between January 1998 and March 2013. Treatment efficacy, complications and the stability of results were all evaluated.
  
  
  RESULTS
  Thirty-five patients were included in the study. The gain of inter-mental-foramen space was on average 7 mm (3-12, standard deviation 1.8 mm). A good occlusal result with dental Class I and no labioversion of the lower incisors was obtained in 27 of the 35 patients (77%).
  
  
  CONCLUSIONS
  Mandibular distraction by symphyseal osteotomy seems to be a quick, safe treatment for an anterior transversal mandibular deficit giving results that are stable over time. Its success depends on good collaboration between the orthodontist and the surgeon, and on strict patient selection.
