迷路瘘是慢性中耳炎合并胆脂瘤的并发症，可导致进行性感觉听力丧失或内耳功能永久性丧失。完全手术切除胆脂瘤并使用完整的耳道壁鼓室成形术和乳突切除术可以保留或改善听力并消除眩晕。报告了一系列 63 例病例的长期结果。手术技术的重要特征包括使用高倍放大手术显微镜、高速钻、抽吸冲洗和对颞骨解剖学的全面了解。此外，外科医生在解剖过程中必须避免鳞状上皮基底膜撕裂或穿孔。在某些情况下，感觉听力在手术后恢复正常，使得成功的第二阶段听力重建成为可能。
Labyrinthine fistula is a complication of chronic otitis media with cholesteatoma which can result in progressive sensory hearing loss or permanent loss of inner ear function. Total surgical removal of cholesteatoma and use of the intact canal wall tympanoplasty and mastoidectomy can result in preservation or improvement of hearing and elimination of vertigo. Long-term results in a series of 63 cases are reported. The important features of surgical technique involve use of high magnification with the operating microscope, a high-speed drill, suction irrigation and thorough knowledge of temporal bone anatomy. In addition, the surgeon must avoid tearing or perforation of the squamous epithelium basement membrane during dissection. In some cases, sensory hearing returns to normal following surgery, making a successful second-stage reconstruction for hearing possible.
