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.
本研究的目的是分析1例特雷彻·柯林斯综合征患者的下颌骨牵张病例。下颌骨牵张是治疗皮埃尔·罗宾序列征患者的一种合适的外科治疗方法，是气管切开术的一种替代方法。在严重发育不全的病例中，或当需要三维矢量控制或下颌角控制时，口外双向或多向装置比口内装置更具优势。在下颌远端节段和下颌联合处固定贯穿克氏针获得的锚固对于新生儿装置的稳定性至关重要。此外，通过在每个骨段使用第二根钢针，口外装置可以改变矢量方向，从而改变新形成的下颌骨的形状。
