Efficacy of application of Norton in dacrystorhinostomy for the treatment of chronic dacryocystitis

Abstract

Objective To investigate the efficacy of application of Norton in nasal endoscopic dacryocystorhinostomy. Methods The data of 100 eyes of 100 cases of chronic dacryocystitis who received dacryocystorhinostomy from Dec.2012 to Dec.2017 were analyzed retrospectively. All cases were divided into 2 groups randomly. The treatment group, 50 cases, were treated with Norton cotton slice in nasal cavity before operation, and the control group, 50 cases, were treated with adrenaline cotton slice before operation. The nasal mucosa was contracted by placing cotton slices twice, once per 5 minutes.in the nasal cavity 10 minutes before operation. All cases underwent endoscopic dacryocystorhinostomy. Results There were 49 cases cured, 1 case improved and no case of ineffective in the treatment group, and in the control group 45 cases cured, 3 cases improved and 2 cases ineffective. The difference of total effective rate was not statistically significant between the two groups (P=0.179). The treatment group had clear visual field, wide visual field and sustained operation.The blood pressure was stable, heart rate fluctuated slightly, less intraoperative hemorrhage. No bleeding occurred after operation.The operation time was shorter, and no obvious complication occurred during and after operation. Conclusion Application of Norton in dacryocystorhinostomy under nasal endoscope has advantages of quick onset, long curative effect and less adverse reactions.
