在喉部术后及喉气管狭窄时，经常需要喉气管重建组织。目前，有关这方面的研究颇多。所用的重建组织有软骨、软骨膜、骨膜、肌肉及皮肤等，虽然有效，但成功率尚低，国移植物易于感染、吸收、移位或受挤压。该文选用２０只兔子作动物试验，旨在寻找进行喉气管修复所用的同种异 Laryngeal tracheal reconstructions are often required in post-throat surgery and laryngotracheal stenosis. At present, a lot of research in this area. The rebuilding tissues used are cartilage, cartilage, periosteum, muscle and skin. Although effective, the success rate is still low, and the metastasis is easy to be infected, absorbed, displaced or squeezed. The article selected 20 rabbits for animal experiments, aimed at finding the same kind of laryngotracheal tube used for repair
