目的:探讨胆脂瘤并发迷路瘘管患者的临床特点和治疗方法。方法:胆脂瘤并发迷路瘘管23例(6.6%)患者中,15例行开放式乳突根治术加鼓室成形术,6例行开放式乳突根治术,2例行乳突再根治术。结果:术后平均随访2年,21例干耳,22例眩晕消失,术后平均骨导听力无明显变化。结论:胆脂瘤中耳炎常并发迷路瘘管,术前尚无可靠确诊方法,颞骨高分辨CT对较大瘘管检出率高,最后确诊靠手术探查;对瘘管区病变的处理应彻底清除病变,修补瘘孔。
Objective: To investigate the clinical features and treatment of cholesteatoma complicated with fistula. Methods: Of the 23 patients (6.6%) with cholesteatoma complicated with fistula, 15 patients underwent open mastoidectomy combined with tympanoplasty, 6 underwent radical mastoidectomy and 2 underwent mastoid radical re - operation. Results: After an average follow-up of 2 years, 21 cases of dry ears, 22 cases of dizziness disappeared, postoperative average bone conduction hearing no significant change. Conclusion: otitis media cholesteatoma often complicated by fistula, preoperative there is no reliable diagnostic method, the temporal bone high resolution CT detection rate of the larger fistula, the final diagnosis by surgical exploration; fistula lesions should be completely removed lesions, repair Fistula hole.
