Lacrimal sac parameters were measured by computed tomography-dacryocystography, and surgical findings were recorded during surgeries. The surgical success rates were compared between the two groups at 12 months after surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>There were 53 patients in group A and 106 patients in group B. In group A, the mean horizontal, sagittal, and vertical lengths were 4.94\u2009\u00b1\u20091.30 mm, 4.88\u2009\u00b1\u20091.17 mm, and 7.85\u2009\u00b1\u20092.03 mm; in group B, these three lengths were 6.16\u2009\u00b1\u20091.25 mm, 5.97\u2009\u00b1\u20091.20 mm, and 10.00\u2009\u00b1\u20092.18 mm, respectively. All three parameters were significantly smaller in group A than in group B. Scar formation in the sac was observed in all patients in group A; it was not present in group B. At 12 months after surgery, the anatomical and functional success rates were 75.47% (40\/53) and 71.70% (39\/53), respectively, in group A; they were 93.40% (99\/106) and 91.51% (97\/106) in group B.
