Bone osteogenesis has been used by many surgeons to compensate dissymmetry due to congenital malformations, diseases or traumas. Bone distraction is the process of generating new bone in a gap between two bone segments in response to the application of graduated tensile stress across the bone gap. Different types of distraction are actually proposed to be an alternative to facial osteotomies or bone grafting techniques. Distraction can be unilateral, bilateral and correct the deficiencies in one, two or three dimensions. The advantages of the distraction osteogenesis are the possibilities to obtain bone lengthening together with simultaneous expansion of the functional soft tissue matrix including skin, muscles, nerves, cartilage, blood vessels and periosteum. Distractors are internal or external devices made of pins or miniplates fixed on the bone and connected by lengthening--screw--systems allowing elongation.
骨生成已被许多外科医生用于补偿因先天性畸形、疾病或创伤导致的不对称。骨牵引是指在骨间隙两端施加逐渐增加的拉应力，从而在两个骨段之间的间隙中生成新骨的过程。实际上，不同类型的牵引被认为是面部截骨术或骨移植技术的替代方法。牵引可以是单侧的、双侧的，能够在一个、两个或三个维度上纠正缺陷。牵引成骨的优点是可以实现骨延长，同时使包括皮肤、肌肉、神经、软骨、血管和骨膜在内的功能性软组织基质同步扩张。牵引器是由固定在骨上的针或微型钢板制成的内部或外部装置，并通过允许延长的延长螺钉系统连接。
