INTRODUCTION
Management of mandibular deformities is challenging. Distraction osteogenesis is a relatively new technique with promising results.
MATERIALS AND METHODS
We selected 12 patients. The osteotomy site decided was proximal to the antegonial notch. Latency time was five to seven days. Consolidation period was eight weeks in eleven cases and six weeks in one case.
RESULTS
In all the patients, appreciable lengthening of mandible was achieved.
DISCUSSION
The greatest advantage of distraction osteogenesis is growth of soft tissue along with the growth of hard tissue. This increases post operative stability.
引言
下颌骨畸形的治疗具有挑战性。牵张成骨是一项有前景的相对新技术。
材料与方法
我们选取了12例患者。截骨部位定在角前切迹近端。延迟期为5至7天。11例患者的巩固期为8周，1例患者为6周。
结果
所有患者的下颌骨均实现了明显延长。
讨论
牵张成骨的最大优势在于软组织随硬组织一同生长。这提高了术后稳定性。
