对8例由中耳乳突瘤引起的中耳瘘管患者进行了术后听力敏锐度和平衡性评估，其中至少一个半规管（5例，外侧; 1例，上级; 1例，后侧; 1例，外侧和上级）在从半规管中清除基质和颗粒的过程中中断。中断的半规管用自体材料如筋膜、软骨膜、骨片和软骨牢固地闭塞。观察期9个月~ 3.3年。7例患者术后听力无变化或改善，1例患者听力下降12 dB。术后失衡持续2周以上的两名患者经历，并消失在术后第二个月和第五个月，分别。术后瘘管症状完全缓解，表明该手术在一期开放式鼓室成形术中是适当的。目前的研究表明，半规管的操作与意识可以进行不损害耳蜗功能，并应非常小心，但不保守，以导致未来的问题，治疗耳蜗瘘管。在某些情况下，半规管的深部瘘管，半规管的中断和/或闭塞可能是最合适的程序。
Evaluation of postoperative hearing acuity and equilibrium was performed in eight patients with labyrinthine fistula caused by cholesteatoma, in which at least one of the semicircular canals (five cases, lateral; one case, superior; one case, posterior; and one case, both lateral and superior) was interrupted during eradication of the matrix and granulations from the semicircular canals. The interrupted semicircular canals were obliterated firmly with autologous materials such as fascia, perichondrium, bone chips, and cartilage. The observation period ranged from 9 months to 3.3 years. Postoperative hearing was unaltered or improved in seven patients, and decreased by 12 dB in one patient. Postoperative disequilibrium lasting more than 2 weeks was experienced in two patients and disappeared at the second and fifth postoperative months, respectively. Relief from fistula symptoms was complete after surgery, indicating adequacy of this procedure in one-stage open-method tympanoplasty. The present study indicates that manipulation of the semicircular canal with awareness can be conducted without damaging the cochlear function, and that the treatment of labyrinthine fistulas should be performed very carefully but not so conservatively as to lead to future problems. In some cases of deep fistulas of the semicircular canals, interruption and/or obliteration of the semicircular canals can be the most proper procedure.
