目的评估完壁式乳突切除术(CWUM)联合鼓室成形术治疗慢性化脓性中耳炎(CSOM)的效果。方法 130例CSOM患者按照手术方式不同分为研究组(完壁式乳突切除术+鼓室成形术)与对照组(开放式乳突切除术+鼓室成形术),每组各65例。术后随访24个月,...目的评估完壁式乳突切除术(CWUM)联合鼓室成形术治疗慢性化脓性中耳炎(CSOM)的效果。方法 130例CSOM患者按照手术方式不同分为研究组(完壁式乳突切除术+鼓室成形术)与对照组(开放式乳突切除术+鼓室成形术),每组各65例。术后随访24个月,比较2组患者治疗前后纯音听力、术后主观听力改善、平均干耳时间及并发症情况。结果研究组与对照组术后24个月的纯音听阈阈值分别比术前降低22.59 d B和11.42 d B;组内手术前后及组间术后听力改善比较差异均有统计学意义(P值均<0.05)。研究组术后24个月主观听力改善优于对照组(P<0.05)。研究组与对照组术后干耳所需时间分别为49.16 d和36.95 d,组间差异具有统计学意义(P<0.05)。2组术后并发症发生率比较差异无统计学意义(P>0.05)。结论 CWUM联合鼓室成形术治疗CSOM对于符合适应证的患者,能够完整清除病灶,改善患者听力,疗效确切。手术医师需要根据患者病变情况合理选择CWUM或开放式乳突切除术。展开更多
目的介绍完壁式乳突切开鼓室成形术治疗活动期慢性化脓性中耳炎的临床效果。方法回顾分析我院采用完壁式乳突切开鼓室成形术治疗的57例(耳)活动期慢性化脓性中耳炎的临床资料。结果48耳术后鼓膜一期愈合,5耳移植筋膜边缘残留裂隙,2-3周...目的介绍完壁式乳突切开鼓室成形术治疗活动期慢性化脓性中耳炎的临床效果。方法回顾分析我院采用完壁式乳突切开鼓室成形术治疗的57例(耳)活动期慢性化脓性中耳炎的临床资料。结果48耳术后鼓膜一期愈合,5耳移植筋膜边缘残留裂隙,2-3周后延期愈合,4耳术后感染鼓膜穿孔未愈合;随访10个月至34个月,无复发病例,57耳的0.5、1.0、2.0、4.0k Hz气导听阈平均值由术前的49.7±9.4d BHL恢复到30.3±8.0 d BHL,气骨导差平均缩小15 d BHL,其中48耳听力有改善。结论采用完壁式乳突切开鼓室成形术治疗活动期慢性化脓性中耳炎,亦可有效清除中耳乳突病灶,重建中耳传导结构,且能保留耳部正常形态,提升患者听力及生活质量。展开更多
