为比较鼻内窥镜下鼻内泪囊鼻腔造孔术改良与传统经鼻外泪囊鼻腔吻合术的疗效及并发症 ,并探讨其影响因素 ,采用随机对照临床验证方法 ,将 6 8例 ( 88眼 )慢性泪囊炎分为治疗组 38例 ( 4 8眼 )和对照组 30例 ( 4 0眼 ) ,两组临床参数差异无显著性。按治疗组及对照组的方法手术 ,随访 5个月以上。比较两组术后疗效及并发症 ,探讨治疗组的影响因素。结果显示 :治疗组治愈率 83.33% ,好转率 10 .42 % ,无效 6 .2 5 % ,总有效率 93.75 % ,与传统手术无差异 ,但治愈率高 ,并发症明显低于传统方法。认为本术式操作简便 ,损伤小 ,并发症少 ,面部无瘢痕 ,治愈率高 ,较好保留眼轮匝肌及睑部诸肌对泪液导流作用。鼻腔状况及术后处理为影响预后的主要因素
To compare the efficacy and complications of intranasal dacryocystorhinostomy under nasal endoscopy and traditional nasal dacryocystorhinostomy, and to explore the influencing factors, a randomized controlled clinical trial was performed to compare the efficacy and complications of intranasal dacryocystorhinostomy 88 eyes). Chronic dacryocystitis was divided into treatment group 38 cases (48 eyes) and control group 30 cases (40 eyes). There was no significant difference in clinical parameters between the two groups. According to the treatment group and control group, the patients were followed up for more than 5 months. The curative effect and complication of the two groups were compared to explore the influencing factors of the treatment group. The results showed that the cure rate of the treatment group was 83.33%, the improvement rate was 10.42%, the ineffective 6.55% and the total effective rate was 93.75%. There was no difference with the traditional operation, but the cure rate was high and the complication was obviously lower than the traditional method. That the operation is simple, less injury, fewer complications, no scar on the face, high cure rate, better retention of orbicularis muscle and eyelid muscles on the diversion of tears. Nasal status and postoperative management as the main factors affecting the prognosis
