[Reconstruction of tympanomastoid using autogenous mastoid cortical bone].

The reconstruction of tympanomastoid, such as scutum, lateral wall of attic, posterior wall of external auditory canal, mastoid cortex and auditory ossicular bone, is an important method to restore the function of middle ear and improve the living quality of patients. At present, there are a lot of new materials used to reconstruct the tympanomastoid, the autogenous mastoid cortical bone is still one of selective materials, we will introduce our experiences and review the related research about those reconstructions using this material in this paper.
