目的:观察激光鼻泪管探通术后联合人工鼻泪管支架逆行植入鼻泪管治疗鼻泪管阻塞的疗效。方法:对筛选出符合手术适应证的54例69眼因鼻泪管阻塞而致严重溢泪伴或不伴溢脓患者,施行激光鼻泪管探通联合鼻泪管内逆行植入人工支架,随访3～12mo,以完全解决或最大程度地改善溢泪症状且泪道冲洗通畅为手术成功的标准。结果:所有患者术中均成功地植入人工鼻泪管支架,手术时间平均为15.48min。术后溢泪症状立即改善,泪道冲洗均通畅。观察3,6,12mo时治愈率分别为100%和97%及91%。结论:鼻泪管激光探通联合人工鼻泪管支架逆行植入术是一种简单、安全、有效的治疗鼻泪管阻塞的方法,且手术无瘢痕,不改变生理解剖结构等优点。

AIM:To observe the effect of nasolacrimal duct laser probing surgery and artificial nasolacrimal stent retrograde implantation in treatment of nasolacrimal duct obstraction.METHODS:A total of 54 patients 69 eyes with nasolacrimal duct obstruction were screened,and those who met the surgical indication,suffering severe epiphora with or without pus overflow were treated with laser nasolacrimal duct probing combined retrograde stent implant and followed up for 3-12 months.RESULTS:All patients were successfully implanted artificial nasolacrimal duct stent,mean operative time was 15.48 minutes.Epiphora symptoms were improved immediately after surgery,lacrimal duct were patent.The time of observing for 3,6 and 12 months,cure rates were 100% and 97% and 91%.CONCLUSION:Laser probing of nasolacrimal duct combined with nasolacrimal duct stent retrograde implantation is a simple,safe and effective treatment method for nasolacrimal duct obstruction,without skin scars,changing of the physical anatomy and so on.
