Background: Adenoidectomy is most common paediatric surgical procedures. Commonly used methods for adenoidectomy are conventional curettage adenoidectomy and endoscopic coblator assisted adenoidectomy. The technique of coblation adenoidectomy has considerable influence on the duration of surgery, the blood lost intra operatively, pain on the first postoperative period.

Methods: Sample selected for study were children of age group 3 to 11 years attending ENT OPD with clinical signs of adenoid hypertrophy, who underwent adenoidectomy during the time period from October 2019 to June 2021. We compared the efficacy of ECA with CCA based on the intra-operative (operative time and bleeding) and post-operative parameters (pain on the first post operative day).

Results: Our study revealed that intra operative bleeding was more in CCA compared to ECA (p<0.001). ECA took more operative time than CCA group (p<0.001). Pain on the first post-operative day was more in CCA than ECA.

Conclusions: Primary objective was comparison of intra operative bleeding among both groups and the outcome was blood loss in ECA was less than CCA. Secondary objective was comparison of operative duration and pain on the first post-operative day and the outcome was, operative duration was less in CCA and pain in the first post-operative day was more in CCA. Our conclusion is that ECA was efficient on the basis of intra operative blood loss and post- operative pain in the first day. CCA was effective in operative duration.
