Tympanoplasty with allograft tympanic membrane and otosteon chain 同种异体鼓膜、听骨链移植鼓室成形术
The positive rate of the disappearance, damage and cirrhosis of otosteon was 94% in patients with granuloma-type mastoiditis. 听小骨消失、病损、硬化出现率为94%。
Conclusion: It can be explained that nano-hydroxyapatite retain a good biocompatibility which is beneficial MSCs to adhesion, proliferation and combination and be used to construct the tissue-engineering artificial otosteon. 结论:说明纳米羟基磷灰石材料保持了它良好的生物相容性,利于细胞黏附、增殖,可结合大量的骨髓间充质干细胞,用于构建组织工程人工听骨。
