目的:探讨乳突根治术失败的常见原因,以提高手术治疗水平,获得干耳。方法:对28例乳突根治术后长期不干耳的患者进行再次手术。结果:28例患者经1～2个月局部换药均获得干耳。无一例眩晕、面瘫等并发症发生。结论:病灶清除不彻底、术腔引流不畅、术后换药处理不当、术腔异物遗留等是乳突根治术失败导致不干耳的原因。乳突腔充分轮廓化,显微镜下彻底清除病灶并确保术腔的引流通畅是防止再次手术的关键。
Objective: To investigate the common causes of failure of radical mastoidectomy in order to improve the level of surgical treatment, access to dry ear. Methods: 28 cases of radical mastoidectomy long-term ear dry ear patients underwent reoperation. Results: 28 cases of patients after 1 to 2 months local dressing were dry ears. No case of vertigo, facial paralysis and other complications. CONCLUSION: The reason of incomplete removal of the lesion, poor drainage of the surgical cavity, improper dressing change after surgery, and residual foreign body in the surgical cavity are the reasons for the failure of radical mastoidectomy. Masticons fully contoured, the microscope completely remove the lesion and ensure drainage of the patency of the cavity is the key to prevent surgery again.
