目的:探讨Medpor支架的医学生物学性能及其在全耳郭再造术中的临床应用和效果。方法:36例先天性小耳畸形,均以耳后乳突区扩张皮瓣包被Medpor支架行全耳郭再造术。结果:36例皆成功,经6个月～5年的随访观察支架无软化、吸收或变形,质地柔软,形态、大小与健侧对称。结论:Medpor作为全耳郭再造术的支架,是一种良好的支架材料。 Objective: To investigate the medical biology of Medpor scaffold and its clinical application and effect in auricular reconstruction. Methods: Thirty - six cases of congenital malformations of the ears were treated by Medpor scaffold with auricle reconstruction. Results: All 36 cases were successful. After 6 months to 5 years of follow-up, the scaffolds showed no softening, absorption or deformation, with soft texture and symmetrical shape and size. Conclusion: Medpor is a good scaffold for the reconstruction of auricular reconstruction.
