从1967年开始,作者们采用分期联合鼓室成形术的方法给9例迷路瘘管患者作了手术,手术对象为:(1)前庭窗区充满肉芽组织。(2)镫骨周围鼓室硬化灶使镫骨底板固定。(3)胆脂瘤与镫骨关系密切,第一次手术时不宜切除。全部患者术前均有平衡失调,表现为程度不等的眩晕。手术时仔细地分离瘘管,保留瘘管表面及其周围鳞状上皮,3—6个月后当残留鳞状上皮发生组织变形并消失时再行二期手术,以筋膜覆盖瘘管并重建鼓室。
From 1967 onwards, the authors performed surgery on staged fistulas by staging with tympanoplasty. The objects of surgery were: (1) The granuloma was filled with the vestibular window. (2) tympanic cavity around the stapes to make the stapes floor fixed. (3) cholesteatoma and tarsal bone is closely related to the first surgery should not be removed. All patients had preoperative balance disorders, manifested as varying degrees of dizziness. During operation, the fistula was carefully separated, the surface of the fistula and the surrounding squamous epithelium were preserved. After 3-6 months, the residual squamous tissue was deformed and disappeared, and then the second operation was performed. The fascia covered the fistula and the tympanic cavity was reconstructed.
