为保证新鼓室含气,近年虽曾采用多种合成材料做成新鼓室内赝复物,以增大鼓室深度,但有因排异严重而被迫再次手术取除者。为寻求更好的生物惰性合成材料,作者用取自由(?)和(?)线织成的波形人工血管残料制备的人工赝复物,达到了预防移植片与鼓岬粘连、保存新鼓室深度而又不被排异的目的。手术在干耳后6～12个月时进行。在手术显微镜下按常规准备受植床,移植片采用自体颞筋膜或外耳道带蒂皮片,用锐剪自人工血管片上按需要裁剪制备赝复
In order to ensure that the new tympanum gas is contained, in recent years, a variety of synthetic materials have been used to create new tympanic prostheses to increase the tympanic cavity depth. However, those who have been forced to undergo surgical resection due to severe rejection have been identified. In order to seek better bio-inert synthetic materials, the authors use artificial prostheses prepared from corrugated artificial blood vessels which are made of threads (?) And (?), To prevent the adhesion between the graft and the promontory, save the new tympanic cavity Depth and not be excluded purpose. Surgery in the dry ear after 6 to 12 months. Under the operating microscope as usual by the preparation of implantation, autologous fascia or external auditory canal pedicled skin graft, with sharp cut from the artificial blood vessel piece on the need to cut the preparation of prosthesis
