Background: Different tonsillectomy techniques were adopted and improved to make the procedure safe and reduce operative time, intra operative blood loss, post-operative morbidity and complications. Aim & Objectives: To compare cold steel dissection and monopolar diathermy methods of tonsillectomy surgery in study population in terms of operative time, intra operative bleeding, post-operative pain and bleeding. Methods: This is a case control study done on 40 patients in Govt medical college hospital anantapuram in Andhra Pradesh India, between January 2023 to May 2023. Patients were randomly selected to have either the right or left tonsils removed by either technique (cold dissection or monopolar dissection technique). We compared both techniques in each side on the same patient. Results:There was no significant difference in operative time between both sides by either technique, Mean duration of surgery by cold steel dissection technique is 7 min while for monopolar cautery dissection technique is 3.96 min .The volume of blood loss in cold steel dissection technique from 2ml to 25 ml (Mean blood loss = 11 ml ) while in monopolar cautery dissection technique blood loss from 1 ml to 20 ml (Mean blood loss = 6 ml).Post-operative pain recorded separately two sides by visual analogue pain score, pain scores are more in monopolar cautery side in immediate post op period (6hrs after surgery). Pain is reduced gradually and second post-operative day the pain scores are almost same in both techniques. Conclusion: Monopolar diathermy method is a safe technique and when compared to CSD technique, MEC technique will take lesser time for performing the surgery & less intraoperative blood loss. Though MEC has more pain in immediate post-operative period when compared to CSD, after 48 hrs post-operative pain is the same for both the techniques.
