目的 探讨自体肋骨 -肋软骨游离移植在颞下颌关节骨性强直治疗中的作用。方法 将肋骨 -肋软骨嵌贴于下颌骨升支后缘进行关节重建 ,术后随访半年至三年。结果 14例成功 ,1例术后复发 ,成功病例的张口及咀嚼功能恢复良好 ,部分患者面颌畸形明显改善。结论 自体肋骨 -肋软骨游离移植治疗颞下颌关节骨性强直 ,不仅骨源丰富 ,取材方便 ,还能重建近似正常的关节解剖结构 ,对改善面颌畸形具有积极作用。
Objective To investigate the role of free rib-free cartilage transplantation in the treatment of temporomandibular joint osteoarthritis. Methods Rib - costal cartilage embedded in the ascending ramus of the mandible for joint reconstruction, followed up for six months to three years. Results 14 cases were successful and 1 case recurred after operation. The mouth and chewing function of successful cases recovered well, and the maxillofacial deformity of some patients was significantly improved. CONCLUSION: Autologous rib-free costal cartilage transplantation for the treatment of temporomandibular joint bony ankylosis not only has rich bone source, easy access to materials, but also can reconstruct approximate normal anatomical structures and has positive effects on the improvement of facial maxillofacial deformity.
