Abstract:
The purpose of this study is to compare the success rates of endoscopic endonasal dacryocystorhinostomy (EN-DCR) and external DCR (EX-DCR) for the treatment of primary acquired nasolacrimal duct obstruction (PANLDO). Prospective randomized comparative study. Study was conducted for 2 years duration in a teaching hospital with 300 cases of endoscopic and 300 cases of external DCR with a follow-up of minimum 6 months. Data regarding surgical outcome and complications were analyzed and compared using χ2 test. In our study, the overall success rate of DCR for PANLDO was 92.6%, there was difference in terms of anatomical or functional success rate between EN-DCR (93.6%) and EX-DCR (91.6%). The incidence rate of post operative complication in our study was lower in Endonasal DCR (27.33%) as compared to External DCR (48%). Patients who underwent EN-DCR had shorter recovery time, less complications and higher satisfaction due to lack of external incision, although final surgical outcomes were comparable between two groups.
摘要:
目的比较鼻内镜经鼻泪囊鼻腔吻合术(EN-DCR)和体外DCR(EX-DCR)治疗原发性获得性鼻泪管阻塞(PANLDO)的成功率。前瞻性随机比较研究。研究在教学医院进行了2年,共进行了300例内镜和300例外部DCR,并进行了至少6个月的随访。使用χ2检验对有关手术结果和并发症的数据进行分析和比较。在我们的研究中,PANLDO的DCR总体成功率为92.6%,EN-DCR(93.6%)和EX-DCR(91.6%)在解剖或功能上的成功率存在差异.在我们的研究中,与外部DCR(48%)相比,鼻内DCR(27.33%)的术后并发症发生率较低。接受EN-DCR的患者恢复时间较短,由于缺乏外部切口,并发症少,满意度高,尽管两组的最终手术结局具有可比性.
