摘要

目的：探讨枕部皮下肌组织瓣在开放式乳突根治术中的应用价值及操作要点。方法回顾性分析2012年4月至2014年1月间北京协和医院完成的29例（29耳）开放式乳突根治术并枕部皮下肌组织瓣填塞乳突腔的患者资料。结果术后随访12-34月。术后乳突术腔干耳率为100%，手术后术腔无分泌物流出的时间为术后21-56d，平均33.5d。术区上皮化的时间为术后35-98d，平均61.7d。自洁功能好，无需清理耳道痂皮。结论在开放式乳突根治术中，应用枕部皮下肌组织瓣进行乳突腔填塞可以获得良好的干耳效果。%Objective To investigate the application and the operation tips of the mastoid obliteration with occipital myosubcutaneous flap in the open cavity mastoidectomy.
