粘弹剂在泪囊鼻腔吻合术中的应用

Dacryocystorhinostomy aided with Viscoelastic materials

目的:探讨提高泪囊鼻腔吻合手术成功率及减少瘢痕的有效方法。方法:手术中应用粘弹剂从泪小点注入泪囊,根据泪囊的大小、形态及部位,切开泪囊,可争取得到较大的泪囊粘膜上瓣,并与鼻粘膜吻合。结果:共42例手术应用此方法,成功率97%。结论:粘弹剂的应用可有效提高手术成功率,减少手术时间及瘢痕长度。

AIM： To explore the effects of viscoelastic materials aided in locating the cut nasal ends of canaliculi in lower lacrimal canaliculi laceration anastomosis. METHODS： At first, the cut nasal ends of lower lacrimal canaliculi were looked for with the aid of microscope or water infusion into upper lacrimal puncta. For invalid cases, viscoelastic materials were injected into upper lacrimal puncta instead of water. RESULTS： Within 29 patients ,suffered from lower lacrimal canaliculi laceration, the cut nasal ends of lower lacrimal canaliculi of 15 cases were successfully found just with the aid of microscope or water infusion into upper lacrimal puncta. For 14 invalid cases, viscoelastic materials were injected into upper lacrimal puncta instead of water, 12 cases were finally found the cut nasal ends of lower lacrimal canaliculi and were smoothly anastomosed.CONCLUSION： Compared with old methods, the cut ends of lower lacrimal canaliculi are easier to be found with the aid of viscoelastic materials, the new technique can increase success rate of lower lacrimal canaliculi laceration anastomosis and save operation time.
