| 摘 要： | 目的：探讨白体肋骨软骨移植（CCG）N建生长期山羊下颌髁突的生长与改建。方法：6只6个月龄雄性山羊左侧颞下颌关节作为正常对照侧，右侧手术切除髁突但保留关节盘行CCG（软骨长度3-5mm）重建髁突。术后即刻、1个月、6个月、18个月行螺旋CT扫描头颅，观察移植骨改建，并通过三维头影测量记录下颌支高度的变化。2名测量者分别进行测量，其中一名在1个月后重复测量，采用SPSS13．0软件包对测量数据分别进行配对t检验。结果：术后移植骨逐步改建，18个月后重建侧与正常侧髁突形态接近；测量者之间和测量者自身2次的测量结果无显著性差异（P〉0．05）；术后即刻、1个月、6个月和18个月，正常对照侧平均下颌支高度分别为58．2mm、61．3mm、68．8mm和76．7mm，实验侧平均下颌支高度分别为60．0mm、59．6mm、68．0mm和74．8mm。结论：保留关节盘的自体CCG（软骨长度3—5mm）重建生长期山羊下颌髁突后，能够改建成接近正常髁突的形态，并维持该侧下颌骨的同步生长发育。

| Abstract: | PURPOSE:The study was designed to use 3-D cephalometry to evaluate costochondral graft reconstruction(CCG) of the mandibular condyle in goats.METHODS:Costochondral graft reconstruction of the mandibular condyle was performed on the right sides in 6 male goats aged 6 months,while the left sides were left as control.The cartilaginous portion of the graft was 3-5mm long.3-D cephalometry was taken to measure the ramus heights of both sides immediately,1 month,6 months,and 18 months postoperatively.The measureme... |
