Résumé
OBJECTIVE To observe the curative effect of external dacryocystorhinostomy(EDCR) and intranasal endoscopic dacryocystorhinostomy(IEDCR)for chronic dacryocystitis, and to evaluatethe postoperative satisfaction of the patients.METHODS According to randomized controlled design, 108 chronic dacryocystitis patients were divided into the intranasal endoscopic dacryocystorhinostomy group and control group, both groups underwent intranasal dacryocystorhinostomy and external dacryocystorhinostomy respectively.The changes of symptom and clinical sign, operation time, hospital day, cost of hospitalization were recorded.All patients were followed up for 1-5years, and the postoperative satisfaction of the patients were investigated by interval satisfaction scale.RESULTS ①There were no significant difference between the groups at the curative effect, operation time and hospital day, the hospitalization cost of the intranasal endoscopic dacryocystorhinostomy group was higher than that of the control group;②The recurrence rate of the intranasal endoscopic dacryocystorhinostomy group and control group were 12.82% and 15.56% respectively after 5 years, Log Rank test ?2=0.394, P=0.530;③ The postoperative satisfaction of the patients in both groups were(81.70?10.242)and(75.72?10.653) score respectively, which were similar to normal distribution, t=-2.974, P=0.004.CONCLUSION The effect of intranasal endoscopic dacryocystorhinostomy for chronic dacryocystitis is similar to external dacryocystorhinostomy.But intranasal endoscopic dacryocystorhinostomy is a more ideal method, because it is minimal invasive technique and doesn't affect the face cosmetology.
