Novel technique to appose flaps using the BioGlue in the external dacryocystorhinostomy.

PURPOSE: To introduce the sutureless technique to appose flaps using the BioGlue composed of bovine serum albumin (45%) and glutaraldehyde (10%) in the external dacryocystorhinostomy (DCR). METHODS: The clinical chart was reviewed, retrospectively. The authors studied 31 case series of 30 patients who underwent the external DCR using the BioGlue in the step of apposing flaps. Instead of the suture technique, BioGlue was applied to appose flaps. Other steps were performed in the similar fashion to the conventional external DCR. And also, authors studied 31 case series of 30 patients who underwent the external DCR with conventional suture technique. RESULTS: Mean follow-up period is 12.5 months in study group and 12.6 months in control group. During mean follow up, 3 cases of membrane formation were observed, and patency of the anastomosis was kept well established in 28 cases (90%) in both groups. CONCLUSIONS: Sutureless apposition of flaps using the BioGlue can be an alternative method for the conventional suture technique in the external DCR. Also, it is easy and safe procedure to perform.
