External Dacryocystorhinostomy: Double-Flap Anastomosis or Excision of the Posterior Flaps?
Ophthalmic Plastic & Reconstructive Surgery.January/February 2007.
This randomized, clinical trial included 63 consecutive patients undergoing DCR. Patients were alternately assigned to two groups on the basis of the pattern of flap anastomosis. An H-shaped incision was created in the lacrimal sac and the nasal mucosa in all patients. In group A, posterior and anterior flaps were separately approximated; in group B, only the anterior flaps were sutured after resection of both posterior flaps. Our study suggests that DCR with double-flap anastomosis has no advantage over DCR with only anterior flaps. 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.
