Objective To evaluate bipolar scissors tonsillectomy by comparing it with traditional cold dissection tonsillectomy. Study Design A prospective, randomized, multi‐unit study. Settings Belfast City Hospital, Royal Victoria Hospital Belfast, and Ulster Hospital Dundonald. Patients Two hundred consecutive patients undergoing tonsillectomy for recurrent or chronic tonsillitis between March 2000 and September 2000. Outcome Measures (1) Intraoperative bleeding, (2) operative time, (3) postoperative pain, and (4) complication rates, including primary and secondary hemorrhage. Results Seventeen patients were excluded from the study for various reasons. The mean age of the study population was 22 years (range, 10–54 y). Seventy‐two percent of patients were female. Twenty‐seven percent of patients were children aged 16 years or under. Median intraoperative blood loss was 5 mL for bipolar scissors tonsillectomy and 115 mL for cold dissection tonsillectomy ( P <.001). The mean operative time was 13 minutes for bipolar scissors tonsillectomy compared with 20 minutes for the cold dissection method ( P <.001). There was no statistically significant difference in the pain scores between the two methods (independent samples t = 1.35; P >.05). The overall primary hemorrhage rate was 2.1%, whereas the overall secondary hemorrhage rate was 16.9%. The hospital readmission rate was 10.3%. The primary and secondary hemorrhage rates were unaffected by the surgical method. Conclusions Bipolar scissors tonsillectomy is a safe technique with a similar morbidity to the cold dissection method. Its use is associated with a significant decrease in both surgical time and blood loss compared with the cold dissection method.
