目前认为,联合进路分期进行鼓室成形术,对中耳疾病包括胆脂瘤的处理是一种理想的手术方法。它有可能在彻底清除病变组织的同时,又保存基本骨性结构和达到鼓膜-听小骨装置的解剖与功能重建。本文报告的目的,旨在讨论二期手术时从中耳和乳突采取再生粘膜的组织学表现。从乳突到咽鼓管鼓室,对大面积缺少粘膜处应使用硅胶膜,以防止粘连和保证含气间隙与咽鼓管鼓室间相交通。硅胶膜应作适当裁剪后铺在中耳内。并用一舌形咽鼓管赝复体插入咽鼓管内,以引导中耳粘膜再生(Glasscock,1976)。再
It is currently believed that the combined approach to tympanoplasty by stages, the treatment of middle ear disease, including cholesteatoma is an ideal surgical method. It is possible to completely remove the diseased tissue, while preserving the basic bony structure and reaching the tympanic membrane - the anatomy and functional reconstruction of the ossicular device. The purpose of this report is to discuss the histological appearance of regenerative mucosa from the middle ear and papilla at the second stage of surgery. From mastoid to eustachian tube tympanic cavity, the lack of mucosal area should be used in a large area of silicone film to prevent adhesions and to ensure that the gas-containing clearance and eustachian tube tympanic phase traffic. Silicone film should be properly cut in the middle ear. And a tongue-shaped eustachian tube prosthesis inserted into the eustachian tube to guide mucosal regeneration of the middle ear (Glasscock, 1976). again
