DCR with single anterior flap anastomosis similar to double-flap surgery in study

Performing dacryocystorhinostomy with double-flap flap anastomosis produces clinically similar results to single anterior flap anastomosis, according to a comparative study by researchers in Turkey.
"Anastomosis by suturing only anterior flaps and excision of the posterior flaps is easier to perform and does not appear to adversely affect the outcome of DCR surgery," the authors said.
Didem Serin, MD, and colleagues at the Sisli Etfal Training and Research Hospital in Istanbul compared the two methods in 63 patients. Surgeons created an H-shaped incision in the lacrimal sac and nasal mucosa in all patients. In one group, surgeons sutured both the anterior and posterior flaps of the lacrimal sac and nasal mucosal. In the second group, surgeons sutured only the anterior flaps; the posterior flaps were excised, according to the study.
At 10.8 months' mean follow-up, both groups had similar success rates — 93.75% for patients with both flaps sutured and 96.67% for patients with the single sutured flap. Investigators also found no significant differences in rates of postoperative bleeding, epiphora and patency scores between the groups, the authors noted.
The study is published in the January/February issue of Ophthalmic Plastic and Reconstructive Surgery.
