    ObjectivesTo conduct a prospective randomized controlled study presenting and comparing bipolar radiofrequency dissection tonsillectomy (BRDT) to cold dissection tonsillectomy (CDT) regarding intra-operative blood loss, operative time, postoperative pain, and postoperative complications including hemorrhage.Materials And MethodsFrom January 2004 to March 2005, 200 children planned to undergo tonsillectomy were included in this study. Children were prospectively randomized into two equal groups: bipolar radiofrequency dissection tonsillectomy and cold dissection tonsillectomy. The operative time and intra-operative blood loss were recorded. Children were asked to record their pain on a standardized visual analog scale on days 1, 4, 7, and 14. All children were reviewed on the 4th, 7th, and 14th day after surgery. Postoperative complications were recorded and dealt with.ResultsThere was a shorter operative time (mean 8.5 minutes, P < 0.001) in the radiofrequency group. BRDT showed a decrease of 7 minutes in the mean when compared to the CDT group. The amount of blood lost during BRDT was minimal (mean 13 cc), with a mean difference of 69 cc when compared to CDT (P < 0.001). There was no statistical significant difference in pain score between the two groups except in the first postoperative day where the BRDT demonstrated a statistically significant lower parameters (P < 0.05). No evidence for statistically significant difference between the two groups regarding postoperative complications.ConclusionBRDT is a new, easy, and safe technique that offers a complete eradication of the tonsillar disease, short operating time, minimal intra-operative blood loss, and a suitable cost with no additional increase in postoperative pain and hemorrhage when compared to the conventional CDT. Our experience promotes BRDT as the preferred method of tonsillectomy.
