本文回顾了二十年来鼓室成形术的进展,以及各种成形材料的应用。着重讨论了在中耳缺乏粘膜的情况下使用成形材料重建鼓室腔的问题。作者于1963年使用硅胶片,1967年又增加了医用6号尼龙(Supramid),在下列几种情况下使用:为了预防镫骨、鼓膜、鼓岬间纤维粘连及鼓膜移植片的粗糙面与上鼓室和面神经隐窝粘连,使用薄硅胶片(厚度为0.005吋)永久放置于中耳腔;如镫骨周围有骨性侵蚀,可用硅胶片剪孔套过镫骨,放在镫骨周围;另一种是在中耳缺乏粘膜的情况下使用厚硅胶片(厚度为0.04吋)
This review reviews the progress of tympanoplasty in the past two decades and the use of various shaped materials. Emphasis is placed on the problem of reconstructing the tympanic cavity using a shaped material in the absence of mucosa in the middle ear. The author used silicone film in 1963, and medical grade 6 Supramid was added in 1967. It was used in the following situations: In order to prevent the rough surface of the tympanic membrane, the tympanic membrane, the promontory fiber adhesion and the tympanic membrane graft, Tympanic cavity and facial recess adhesions, the use of thin silicone film (thickness 0.005 inches) permanently placed in the middle ear cavity; such as tarsal bone erosion around the available silicone shears over the stapes, placed around the stapes; One is the use of thick silica film in the absence of the mucous membrane in the middle ear (0.04 "in thickness)
