To report the success rate of endoscopic radiofrequency-assisted dacryocystorhinostomy with double stent and the use of a Griffiths collar button.
A prospective, single surgeon, uncontrolled, interventional case series study was designed to include 112 patients with nasolacrimal duct obstruction. Endoscopic radiofrequency-assisted dacryocystorhinostomy (ERA-DCR) with insertion of a Griffiths collar button was done on 102 patients with unilateral nasolacrimal duct obstruction and 10 patients with bilateral nasolacrimal duct obstruction. The operation was defined as a success if: a) preoperative epiphora was resolved; b) nasolacrimal patency was achieved as confirmed by lacrimal irrigation as well as by endoscopic observation of fluorescein dye flowing through the surgical ostium on lacrimal irrigation.
A total of 122 ERA-DCR procedures was done, of which 117 procedures involved cases of primary acquired nasolacrimal duct obstruction (PANDO) and five procedures involved cases of previously failed endonasal DCR. Two failures were observed in this study out of the 117 procedures done on PANDO cases. The success rate is computed at 98% (115/117). The postoperative follow-up period was 28.08 +/- 14.7 months.
Endoscopic radiofrequency-assisted dacryocystorhinostomy with double stent and the use of a Griffiths collar button shows a success rate of 98% in the long-term patency of the intranasal ostium.
报告内镜下射频辅助双支架泪囊鼻腔造口术联合使用格里菲斯领扣的成功率。
设计一项前瞻性、单术者、非对照、介入性病例系列研究，纳入112例鼻泪管阻塞患者。对102例单侧鼻泪管阻塞患者和10例双侧鼻泪管阻塞患者进行了内镜下射频辅助泪囊鼻腔造口术（ERA-DCR）并插入格里菲斯领扣。若满足以下条件，则手术定义为成功：a）术前溢泪症状缓解；b）泪道冲洗及泪道冲洗时通过手术造口观察到荧光素染料流动，证实鼻泪管通畅。
共进行了122例ERA-DCR手术，其中117例为原发性后天性鼻泪管阻塞（PANDO）病例，5例为既往鼻内镜下泪囊鼻腔造口术失败病例。在对PANDO病例进行的117例手术中，本研究观察到2例失败。成功率计算为98%（115/117）。术后随访期为28.08±14.7个月。
内镜下射频辅助双支架泪囊鼻腔造口术联合使用格里菲斯领扣在鼻内造口长期通畅方面成功率达98%。
