严重的颌骨发育不良因病情复杂,使修复重建治疗非常棘手。牵引成骨技术(distraction osteogenesis,简称DO技术)通过特殊的装置,使截开的骨断面之间在定向牵引力作用下产生新骨,并使骨段周围软组织同步生长。这一新技术的临床应用,为复杂颌骨畸形的矫正提供了一个新的途径。我们应用口内颌骨DO技术治疗2例常规外科手术难以矫治的颌骨发育畸形,效果满
Severe jaw dysplasia due to the complex condition, the repair and reconstruction of the treatment is very difficult. Distraction osteogenesis (DO technique) A special device is used to create new bone under the action of directional traction between the fractured bone sections and to synchronously grow the soft tissues around the bone fragments. The clinical application of this new technique provides a new way for the correction of complex jaw deformities. We use oral DO DO technology to treat 2 cases of conventional surgical correction of maxillofacial deformity, the effect is full
