Comparison of Surgical Outcome of Bipolar Scissors with Conventional Cold Dissection Tonsillectomy.

Abstract

Background The tonsillectomy is the most common Ear, Nose, and Throat (ENT) surgical procedure. Different methods have been used to improve the outcome of the surgery. One such method is tonsillectomy performed with bipolar scissors. In our scenario, the comparison of bipolar scissors tonsillectomy with conventional cold dissection has not been done. Objective To compare the surgical outcomes of bipolar scissors tonsillectomy and conventional cold dissection tonsillectomy. Method A prospective randomized study was conducted in 40 patients who underwent tonsillectomy on one side using bipolar scissors and on the other side using conventional cold dissection. Intraoperative blood loss, operation time, postoperative pain, and postoperative hemorrhage were all analyzed in both surgical techniques. Result The median operative time was 10 minutes for bipolar scissors compared with 12 minutes for conventional cold dissection, with a p-value of 0.390 which was not statistically significant. The median blood loss was 48 mL on the bipolar scissors side and 60 mL on the conventional cold dissection side, with a p-value of 0.232 which was also not statistically significant. The overall postoperative hemorrhage rate was 12.5%. Of these, 4 (10%) occurred on the bipolar scissors side (left side mainly) and 1 (2.5%) on the conventional cold dissection side (also left side), with a p-value of 0.002 which was statistically significant. There was no statistically significant difference in the pain scores between the two methods in both rest and swallowing (p > 0.05). Conclusion The bipolar scissors did not show any benefit over conventional cold dissection in terms of surgical time, intraoperative blood loss, or postoperative pain. However, postoperative hemorrhage was more common with bipolar scissors. Therefore, conventional cold dissection remains a safe technique for tonsillectomy in adult patients.
