胆脂瘤型中耳炎并发迷路瘘管的手术治疗

目的探讨胆脂瘤型中耳炎并发迷路瘘管的临床特征及手术治疗方法。方法回顾性分析胆脂瘤型中耳炎并发迷路瘘管20例患者的临床资料，其中2例行开放式乳突根治及鼓室成形术，16例行开放式乳突根治术，2例行乳突再次根治术。结果全部患者一期修复瘘管，术后随访眩晕症状明显改善。纯音测听平均骨导阈值（0．5、1、2、4kHz），12例术后听力无明显变化，2例术后听力有不同程度的提高，6例术后听力有轻度下降，平均下降15dB以上。结论对胆脂瘤型中耳炎患者应高度重视迷路瘘管存在的可能性，手术时应彻底清除瘘管区病变、修补瘘孔。

Surgical treatment of labyrinthine fistula caused by chronic otitis media

Objective To discuss the clinical characteristics and surgical management of labyrinthine fistula caused by chronic suppurative otitis media （ CSOM ） . Methods Clinical data of 20 cases with labyrinthine fistula caused by CSOM and surgically treated from 2006 to 2011 was analyzed retrospectively. One-stage repair of fistula was performed in all cases. Results All patients were followed up for six months to five years postoperatively. Vertigo got eliminated or improved in all cases. The postoperative average bone conduction thresholds （ 0.5 , 1 , 2 and 4 kHz ） showed no change in 12 ears, improvement in 2 ears and slight decline in 6 ears. Conclusions High attention should be paid to the possibility of labyrinthine fistula in patients with CSOM. Successful surgical management should include thorough removal of inflammatory lesion and complete repair of fistula.
