摘要
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 reasons for the failure of radical mastoidectomy in order to improve the result of treatment and obtain a dry ear.Method：Twenty-eight cases,who achieved no dry ear after radical mastoidectomy,underwent secondary surgery.Result：All cases obtained dry ear without vertigo or facial paralysis after operation and postoperative dressing.Conclusion：The reasons for the failure of radical mastoidectomy result from the incomplete clearance of lesions,the insufficient ventilation of mastoid cavities,the inappropriate postoperative dressings or the residual foreign bodies in surgical cavity.It is the key points to achieve skeletonization adequately,to eliminate the pathological tissues thoroughly under microscope,and to ensure unobstructed drainage of surgical cavities for preventing secondary surgery.
