AIM: To investigate the therapeutic effect of endoscopic dacryocystorhinostomy in the treatment of acute dacryocystitis.

METHODS: Totally 55 patients with acute dacryocystitis was divided into two groups according to the clinical manifestations: the group of redness and swelling and the group of abscess rupture. The bleeding and pain after operation were observed. Operation effect and skin scar of lacrimal sac area was observed and compared between two groups.

RESULTS: The patients were followed up from 3mo to 2a, and effective rates of the two groups of patients were compared, which showed no statistically significant difference(χ²=0.307, P>0.05). Surgery before the abscess ruptured had the minimal impact on the appearance. The appearance impact of the group of abscess rupture was higher than that of the group of redness, and there are statistically significant difference(χ²=12.44, P<0.05).

CONCLUSION: Endonasal endoscopic dacryocystorhinostomy is an effective method on the treatment of acute dacryocystitis. Early surgery has the advantages of quick recovery, scarlessness and high efficiency. Therefore, it worthy of clinical promotion.
