为了防治中耳根治术后开放的中耳乳突腔再感染并提高听力,自1967—1976年作者对167名各种病变的乳突根治术后患者进行部分重建术或完全重建术。前者计74耳,系指乳突腔上皮生长良好、鼓室腔病变及分泌物来源一旦清除保守治疗能达到干耳者便行部分重建术。根据鼓膜病变情况,将此术分为三种类型: 1.鼓膜缺损、中耳粘膜暴露:共47耳,24耳术时已干耳,23耳术时仍有分泌物且鼓室腔充满肉芽。手术经外耳道进行,在鼓环外侧1—2毫米处作一圆形切口越过面神经嵴,分离上皮层并向上翻转,于上方形成一个向前另一向后的两个皮片,将切口与纤维鼓环间的剩余皮肤切除,清除底板或镫骨及圆窗周围肉芽,尽可能保存粘
In order to prevent the re-infection and improve the hearing of the middle ear and the middle ear after the radical mastectomy, from 1967 to 1976, the authors performed partial or total reconstruction of 167 patients undergoing radical mastectomy with various lesions. The former refers to 74 ears, means that the mastoid cavity epithelial growth well, the tympanic cavity lesions and secretions of the source once the removal of conservative treatment can reach dry ear who will undergo partial reconstruction. According to the situation of the tympanic membrane, the operation is divided into three types: 1. Tympanic membrane defect, the middle ear mucosa exposure: a total of 47 ears, 24 ear surgery has dry ears, 23 ear surgery still secretions and tympanic cavity full of granulation. Surgery was performed via the external auditory canal, a circular incision was made 1-2 mm outside of the drum ring across the facial nerve crest, the epithelial layer was separated and flipped up to form an upper, two forward, The remaining skin between the ring resection, remove the floor or stapes and round window around the granulation, as far as possible preservation of sticky
