Abstract
In DCR, the lateral aspect of the dacryocyst and the nasal mucosa are incised, and the mucosal valves are sutured together. In DCR-A, the occluded section of the dacryocyst or nasolacrimal duct was trimmed and anastomosed by circumferential suturing through a hole in the nasal mucosa. The success rate and the requirement for postoperative therapy were compared between 21 sides of DCR patients and 11 sides of nasal DCR-A patients. DCR-A was significantly better than conventional DCR. No additional postoperative therapy was required for DCR-A. DCR-A improves symptoms of nasolacrimal duct obstruction to a greater extent than conventional DCR and does not require additional postoperative treatment.
