中耳乳突相关结构的重建对恢复中耳功能,改善患者术后生活质量起重要作用。随着相关材料学方面的发展,不断有新材料应用于中耳乳突功能的重建,但自体材料因无免疫原性、不产生额外费用、易于塑形、术后效果稳定等优点,在临床实践中仍占重要一席。自体乳突骨皮质在绝大多数中耳乳突术前都保持完整或相对完整,然而行完壁式或开放式乳突根治或乳突探查术时却常常被磨除或弃用,造成不必要的浪费。充分利用自体乳突骨皮
The reconstruction of the structure of the middle ear mastoid may play an important role in restoring the middle ear function and improving the postoperative quality of life. With the development of related materials science, there are constantly new materials used in the reconstruction of the function of the middle ear milk, but the self-material due to no immunogenicity, no additional costs, easy to shape, the advantages of postoperative stability in the clinical Practice still occupies an important seat. Autologous mastoid cortical bone in the vast majority of the middle ear mastoid surgery remain intact or relatively intact, but after the line wall or open mastoid radical or mastoid exploration is often worn away or abandoned, resulting in not Necessary waste. Make full use of self-papillary bone skin
