耳鼻喉器官的某些功能障碍或美容缺陷常需作骨或软骨移植矫治.现将有关资料综述如下. 1 概述骨分松质骨及皮质骨.前者有活的骨细胞、结构疏松、表面积大、易成活,但支撑力差.临床上常以新鲜自体松质骨作为骨移植的标准材料.若处理不当,致骨表面细胞坏死,受植床血供营养不良以及固定不稳而造成失败.失败率可达13～30%.皮质骨富有细胞外基质,限制营养弥散,其最大弥散能力为0.3mm.成骨能力差,但支撑力强.
Some ENT organ dysfunction or cosmetic defects often require bone or cartilage transplantation for correction. Now the relevant information is summarized as follows.1 Overview bone cancellous bone and cortical bone. The former has a living bone cells, loose structure, large surface area , Easy to survive, but the support is poor.Clinical often with fresh autologous cancellous bone as a standard material for bone transplantation.If not handled properly, the bone surface caused by cell necrosis, impaired by implanted blood supply and unstable instability caused by failure. Failure rate of up to 13 to 30% .Cortical bone rich in extracellular matrix, limiting the nutritional dispersion, the maximum dispersion capacity of 0.3mm. Osteoblasts poor, but strong support.
