Abstract: Objective: To compared the influence of bipolar coagulation and conventional stripping method on patients before and after tonsillectomy. Methods: Eighty patients were divided into bipolar electrocoagulation group 43 cases and control group 37 cases. The control group were performed conventional stripping method to dissect the tonsil,while the bipolar electrocoagulation group were treated by bipolar electrocoagulation. The intraoperative bleeding volume,operation time,postoperative pain,the time to resume normal activities and normal diet,and the shedding of pseudomembrane were recorded in the two groups. Results: The operation time and bleeding volume of the bipolar coagulation group were less than those of the control group; the bipolar coagulation group took less time to resume normal diet and suffered less postoperative pain than the control group,but took longer time to shed the pseudomembrane. The difference was statistically significant( P 0. 01). Conclusions: The bipolar electrocoagulation is superior to the conventional dissection method in tonsillectomy. It has the advantages of less bleeding,shorter operation time,less postoperative pain and earlier resumption of diet. The method is easy to grasp and worth popularizing.
