Introduction:Tonsillectomy is a highly prevalent surgical procedure performed on the head and neck region globally. The procedure is performed using many ways, with the most common ones being cold dissection and bipolar electrocautery techniques.Aim:Our purpose in this study is toThis study aimed to evaluate and compare the occurrence of postoperative complications between the use of Electro dissection and Bipolar Diathermy.Materials and Methods: This study was a prospective randomised clinical trial conducted on 100 paediatric patients who underwent tonsillectomy at Government Theni Medical College in the Otorhinolaryngology department between January 2023 and May 2024. The patients were divided into two groups: Group A and Group B, each consisting of 50 children. Tonsillectomy was performed using either the Dissection and Snare method (Group A) or the Bipolar Diathermy method (Group B), both under General Anaesthesia. Various factors, such as surgery duration, intraoperative blood loss, postoperative haemorrhage, local pain intensity, and incidence of nausea and/or vomiting, were recorded and compared between the two groups to determine the superior technique. The data were analysed using SPSS software (ver-22), with a p-value of less than 0.5 considered statistically significant.Results: The average duration of the surgical procedure using bipolar diathermy was 47.36±8.72 minutes, while the average duration for the dissection and snare approach was 67.83±18.64 minutes. The average amount of blood lost during dissection and snare procedure was 62.27±13.73 ml, while the average blood loss during the bipolar diathermy approach was 36.49±5.93 ml. The postoperative pain, as measured by the Visual Analogue Scale (VAS), indicated that the discomfort was greater in the Bipolar Group (Group B) from Day 0 to Day 5. Nevertheless, there was minimal disparity in postoperative pain between the two groups on Day 14. During our investigation, we saw two instances of primary bleeding in the dissection and snare method, but no cases were observed in the bipolar diathermy method. There were two cases of secondary bleeding observed in the dissection and snare approach, while there were eight cases of secondary haemorrhage observed in the bipolar diathermy method.Conclusion:The use of bipolar electrocautery for tonsillectomy is advantageous due to its simplicity, shorter duration of the process, and reduced amount of blood loss during surgery. Dissection and snare tonsillectomy is a well-established procedure that has been proven to have lower levels of post-operative pain and complications. As a result, it is more readily accepted by patients
