Auricular cartilage has been used clinically as an alternative material to costal cartilage for implantation during laryngotracheal reconstructive surgery. Little information is available concerning the healing characteristics or the durability of these two types of graft. The authors of this study examined the rate of epithelialization and the survival of cartilage in a rabbit model of anterior tracheal wall reconstruction and directly compared auricular and costal cartilage grafts. Auricular cartilage was found to epithelialize faster than costal cartilage. Both types of graft survived well after implantation. The superior healing characteristics of auricular cartilage make it a desirable material for laryngotracheal reconstruction.
耳廓软骨已在临床上用作喉气管重建手术中植入的肋软骨替代材料。关于这两种移植物的愈合特性或耐久性的信息很少。本研究的作者在兔前气管壁重建模型中检查了上皮化率和软骨的存活率，并直接比较了耳廓软骨移植物和肋软骨移植物。结果发现耳廓软骨的上皮化速度比肋软骨快。两种移植物植入后均存活良好。耳廓软骨优越的愈合特性使其成为喉气管重建的理想材料。
