Abstract：Objective To analyze the efficacy of the continuous irrigation system in otoscopy surgery for mastoid cholesteatoma.Methods Using a random number table method,60 eligible patients were numbered according to the order of consultation and randomly assigned in a 1:1 ratio to either the continuous irrigation otoscopy group(n=30)or the non-irrigation microscopy group(n=30).The operation time,dry ear time,postoperative pain score(Visual Analogue Scale,VAS),hearing improvement,and complication rates were compared between the two groups.Results The operation time in the continuous irrigation otoscopy group was(119.13±40.05)min,and(128.13±36.39)min in the non-irrigation microscopy group,showing no statistically significant difference(t=0.71,P>0.05).The dry ear time in the continuous irrigation otoscopy group was significantly shorter than that in the non-irrigation microscopy group[(7.96±2.53)weeks vs.(9.20±2.16)weeks,t=2.04,P<0.05],and the postoperative pain score was also significantly lower[(2.60±1.10)vs(3.47±1.07),t=3.09,P<0.01].There were no statistically significant differences between the two groups in hearing improvement(air conduction threshold,air-bone gap)or complication rate(20.00%in the otoscopy group vs.16.67%in the microscopy group,χ2=0.22,P>0.05).Conclusion Continuous irrigation during otoscopic surgery for mastoid cholesteatoma is less invasive,less painful,faster recovery,more effective and safer.
