简介:目的探讨耳源性颅内并发症的临床特点及诊治措施。方法回顾分析2003-2010年我科收治的21例耳源性颅内并发症患者的临床资料,病例包括脑脓肿9例、脑膜炎5例、静脉窦血栓性静脉炎4例、硬膜外脓肿3例,继发于胆脂瘤型中耳炎14例、骨疡型中耳炎3例、隐蔽性中耳炎2例、Modini畸形2例。21例均行耳部及头颅cT平扫检查,其中6例未发现颅内病变,经行磁共振成像(MRI)检查后确诊。分别行单纯乳突根治术8例、乳突根治术+脑脓肿穿刺引流6例、乳突根治术+颅钻孔脑脓肿引流1例、乳突根治术+脑脓肿切除术1例、乳突根治术+静脉窦切开脓肿清除及血栓取出2例、外淋巴漏修补术2例。结果随访1-2年,1例死亡,其余20例治愈,其中19例干耳,1例术腔仍有少量分泌物。全部患者颅内并发症无复发。结论胆脂瘤型和骨疡型中耳炎仍是耳源性颅内并发症的最常见病因,应提倡对这两种危险性中耳炎早期进行手术治疗。临床高度怀疑颅内并发症,CT平扫阴性病例,需行MRI检查。乳突切除进路的显微微创手术有效,无需开颅。
