Background: Tonsillectomy is one of the most common procedures performed by otolaryngologists. It is a surgical operationthat removes both Palatine tonsils from the tonsillar fossa. It is typically performed in youngsters for recurrent tonsillitis andtonsillar hypertrophy.

Objective: To compared the dissection and diathermy methods of tonsillectomy and evaluate their advantages anddisadvantages during surgery and convalescence.

Methods: This is was a retrospective analysis of 400 patients from January 2015 to January 2020 of otorhinolaryngologydepartment in Banga Bandhu Sheikh Mujib Medical Collage Hospital. Out of total 400 patients 200 patients underwenttonsillectomy by dissection method and rest 200 patients underwent electro cautery method. Data were generated through recordreview using a checklist. A total of 400 patients were analyzed in respect of operation methods, operation time, and amount ofblood loss, post operative complications, duration of hospital stay in addition to age & sex distribution separately for comparison.

Results: The overall hospital stayinng in both types was 1-3 days. The average intra operative blood loss was 5-7 ml withcautery and average 50 ml with dissection method. The average operative time was 25-30 minutes with dissection method and10-15 minutes with cautery. We found higher amounts of blood loss and intra - operative time with dissection method thanelectrocautery. The Chance of Secondary haemorrhage was more in electro - cautery method than dissection method. Pain,Scar formation, odynophagia were more in cauterization method. Complete healing time was more in cauterization methodthan dissection method. There was no death in both methods.Conclusion: Although per- operative blood loss, operative time were less in cauterization method but post operative bleeding,pain, odynophagia and infection were more in electro cauterization method. In both methods, there were some advantages andsome disadvantages.
