In the last 10 years different types of lasers were used for dacryocystorhinostomy (DCR). Between April 1998 and August 1999, a fibreoptic erbium laser DCR was performed on 12 patients. Eight cases were for a presaccal stenosis and 4 cases for a postsaccal stenosis. An erbium laser with a specially designed handpiece was used endonasaly and transcanaliculary. Preoperative epiphora was present in all patients. Double bicanalicular nasal silicone tubes were placed during surgery in all cases. The 3 cases of postoperative failure included 2 cases of presaccal stenosis and 1 case of the postsaccal group; failure manifested with recurrent epiphora/dacryocystitis; the onset of symptom recurrence varied from 9 weeks to 11 weeks postoperatively. Laser-assisted DCR includes the avoidance of a cutaneous incision, excessive tissue injury, the advantage of short operation time and precision. Suitable indications for the erbium laser are stenoses in the canaliculi, in the sac, but also for bone lacrimal bone cutting.
在过去10年中，不同类型的激光被用于泪囊鼻腔吻合术（DCR）。1998年4月至1999年8月，对12例患者进行了光纤铒激光DCR。8例为泪囊前狭窄，4例为泪囊后狭窄。使用带有特殊设计机头的铒激光经鼻内和经泪小管操作。所有患者术前均有溢泪症状。所有病例在手术中均放置了双泪小管鼻硅胶管。术后失败的3例包括泪囊前狭窄2例和泪囊后组1例；失败表现为复发性溢泪/泪囊炎；症状复发的时间从术后9周至11周不等。激光辅助DCR包括避免皮肤切口、减少组织损伤、手术时间短和操作精确等优点。铒激光的合适适应证包括泪小管、泪囊狭窄，也适用于泪骨切开。
