自体肋软骨移植术前评估内容及方法的研究进展

Research progress on the contents and methods of preoperative evaluation of autologous costal cartilage transplantation

自体肋软骨(Autologous costal cartilage)因其良好的生物学特性而广泛应用于面部畸形的修复重建。然而,肋软骨性质会由于年龄、性别、内分泌水平的不同而发生变化,进而对术后软骨支架的形态及稳定性产生影响。因此,对肋软骨性质进行精准的术前评估将有助于术中肋软骨的切取、雕刻的规划及术后并发症的管理。本文围绕X线片、CT、超声等方法对肋软骨长度、宽度、厚度、钙化及蜂窝组织的评估展开综述,并展望肋软骨性质精准评估的未来趋势。

Autologous costal cartilage is generally used in the reparation and reconstruction of facial deformity because of its favourable biological properties.Nevertheless,the characteristics of costal cartilage can be influenced by certain factors as age,gender and endocrine,which might significantly affect the aesthetics and stability of cartilage framework.Therefore,an accurate preoperative evaluation of cartilage characteristics can be of great help for harvest and carving intraoperatively and the management of complications after surgery.In this paper,the evaluation of length,width,thickness,calcification and honeycombed phenomenon via X-ray,CT and ultrasonography was reviewed,and the future trend of accurate evaluation of costal cartilage properties was prospected.
