摘要
采用成都地区青春前期家养杂种猪6只,进行自体肋骨肋软骨移植颞颌关节成形术的实验研究。结果表明,移植物与受植床愈合良好,无移植骨的坏死吸收,移植物有适应性改建发生,并有不断的软骨成骨性生长;术后12周有成形关节新生髁突和髁颈的改建形成,手术对健侧关节及下颌骨无不良影响。实验结果提示,自体肋骨肋软骨具有许多和髁突相似的生物学特性,在生长期具有独特的生长能力,是迄今为止青少年者患最为理想的髁突整复材料。
Experimental investigation using 6 domestic pigs were carried out in order to studythe costochondral graft in TMJ arthroplasty.The right condyle was excised andreplaced with autogenous costochondral.The operated animals were killed at 6,12 and 18 weeks.The specimens of the TMJ were examined by means of anatomy,x-ray andlight microscopy.The results showed as following:1.The healing of the graft in receiving area was good and no necrosis or absorptionwas found.The graft has capacity for remodelling into an adaptive mandibular condyle,and can grow continously in juvenile.2.No pathologic changes in the unoperated joint and mandible.So,we can say that the costochondral is the most ideal graft for condyle reconstru-ction in juvenile.
