It is a great clinical challenge for otorhinolaryngology to repair and reconstruct the laryngeal cartilage defects caused by laryngocarcinoma,laryngostenosis or trauma.For the lack of blood vessels,the repair and regeneration ability of the cartilage is poor.Scaffolds are needed in the repair and reconstruction of laryngeal cartilages.Currently,the widely used scaffolds include autologous scaffolds,allogeneic scaffolds and metallic materials.In recent years,tissue engineering scaffolds,which is still in the research stage,shows a good prospect.This article reviews the structure characteristics,reconstruction method and clinical application of the above scaffolds.
