简介:目的探讨纤维蛋白封闭剂(fibrinsealing,FS)在功能性鼻内镜鼻窦手术中的临床应用价值。方法随机将163例行鼻内镜鼻窦手术患者分成FS组、Merocel高膨胀材料组和凡士林油纱条组,比较不同填塞材料的术后临床表现及远期影响。结果FS组在鼻内镜鼻窦手术中止血效果差于高膨胀材料及凡士林油纱条组,但术后头痛及鼻腔疼痛较轻,鼻黏膜反应轻,创口愈合快,鼻黏膜上皮化快,鼻腔粘连少。结论鼻内镜鼻窦手术中应用FS术后头痛及鼻黏膜反应轻,值得临床进一步实践、应用。

简介:目的探讨用改良圈匙娩核并注重粘弹剂应用对防止小切口非超声乳化白内障囊外摘出人工晶体植入术并发症的作用。方法用改良圈匙娩核并注重粘弹剂应用对355例白内障行小切口非超声乳化白内障人工晶体植入术。结果术后三天矫正视力≥0.5者291眼达82%,脱残339眼(95.5%)脱盲315眼(98.9%)。术后角膜水肿39眼,占10.98%均在3~6天后恢复透明。后囊破裂7眼,占1.97%,前房出血4眼,占1.13%。瞳孔轻度变形10眼,占2.8%,暂时性高眼压4眼,占1.13%。结论在行小切口白内障囊外摘出人工晶体植入时,应用改良后的圈匙娩核并注重粘弹剂应用,就会明显减少并发症,达到良好的效果。
简介:目的探讨鼻腔鼻窦鳞状细胞癌侵犯眼眶时保留或剜除眼球对生存率和复发率的影响.方法回顾性分析1989年1月~1998年2月我院收治的43例侵犯眶骨壁和眶骨膜的鼻腔、鼻窦鳞状细胞癌患者的临床和随访资料,其中25例剜除眼球,18例保留眼球.比较患者的3年生存率和复发率.结果随访38~126个月,43例患者中,眼球剜除组3年生存率为56%(14/25),局部复发率为36%(9/25),保留眼球组3年生存率为55.5%(10/18),局部复发率为38.8%(7/18),其中1例为眶内复发.结论经术前或术后放疗,对侵犯眶骨壁和眶骨膜的鼻腔、鼻窦鳞癌,保留眼球组与剜除眼球组相比:有相似的局部复发率和生存率,但保留眼球提高了术后生活质量.
简介:传统的石蜡包埋病理诊断方法由于操作处理所需时间长(一般70~80h),所以不适应现代临床医学快速诊断的要求.
简介:目的:探讨裂隙灯眼前段处理系统在眼科临床工作中的各种实际应用状况及操作技巧。方法:应用配置佳能PowerShotA720IS型数码照相机(1200万像素)SLM型裂隙灯显微镜检查眼部病变情况,并在裂隙灯下根据不同的病变位置,在不同色彩、角度下进行照相(放大倍率×10;×16;×20)。结果:采集不同种类疾病具有代表性照片:眼睑及结膜肿物、结膜裂伤、角膜炎、角膜异物、翼状胬肉、前房积血、前房角异物等如图示。结论:裂隙灯眼前段处理系统的应用为临床医疗文献提供直接定性依据,给患者了解自身病情带来便利,照片直观、经济,在眼科领域的临床应用具有广阔的前景。
简介:目的方法结果结论分析青光眼小梁切除术后浅前房的原因及治疗效果。对2003年2月-2008年1月126例(138眼)青光眼小梁切除术后浅前房者(37眼)进行回顾性分析。138眼小梁切除手术有37眼(26.81%)发生浅前房,其发生原因有:滤过过强17眼(45.95%),结膜瓣渗漏14眼(37.84%),脉络膜脱离2眼(5.41%),睫状环阻塞性青光眼1眼(2.7%),其它3眼(8.1%)。其中33眼(89.19%)经保守治疗治愈,4眼(10.81%)经前房注射透明质酸钠治疗,使前房形成。青光眼小梁切除术后浅前房发生率较高,大部分经保守治疗可恢复正常,透明质酸钠在前房重建中效果良好。
