慢性泪囊炎是眼科的常见病，在繁多的疗法中，当以泪囊、鼻腔粘膜吻合术疗效最佳，但仍有2－15％手术失败。我们经多年探索、改进，从筛骨纸板处打口，计放筛窦，继而完成泪囊、鼻腔粘膜吻合术，使该手术简单易行，提高了手术成功率。作者自1995年3月至1997年12月，共做此种手 Chronic dacryocystitis is a common disease in ophthalmology. In many therapies, when lacrimal sac and nasal mucosa anastomosis are the best, 2-15% of them still fail. After years of exploration and improvement, we started to drill mouth from the ethmoid cardboard and count the ethmoid sinus to complete the lacrimal sac and nasal mucosa anastomosis, which made the operation easy and improved the success rate of operation.
