The purpose of this study was to analyze a case of mandibular distraction in a case of Treacher Collins syndrome. Mandibular distraction is an adequate surgical treatment of patients with Pierre Robin sequence and represents an alternative to tracheostomy. In severe hypoplastic cases or when three-dimensional vector control or gonial angle control is necessary, extraoral bidirectional or multidirectional devices have an advantage over intraoral devices. The anchorage obtained with transfixing Kirschner wires fixed in the mandibular distal segment and symphysis is crucial in neonates for the stability of the devices. Moreover, with the use of a second pin for each bone segment, the extraoral devices allow to modify the vector orientation and consequently the shape of the newly formed mandible.
