In order to contribute to the debate on the optimal treatment, we intended to assess the efficacy and safety of the TWS versus monopolar J Otolaryngol ENT Res. 2018;10(6):400-404. 400 Abstract Aim: To prospectivelycompare monopolarelectrocautery tonsillectomy and thermal welding system (TWS) tonsillectomy in adult patients. Methods: Fifty patients over 20 years old, admitted for tonsillectomy between January 2010 and March 2012, were randomized to have one tonsil removed using monopolar

... autery and the other tonsil removed using the TWS. Subjects used the FACES scale to rate the pain on each side 21 days postoperatively. Postoperative hemorrhaging and tonsillar fossa woundhealingwere also recorded. Results: The mean time required to remove one tonsil was 8.3±1.5 min for the TWS and 7.5±1.6 min for monopolar electrocautery (p=0.033). There was no significant difference between monopolar elecrocautery and TWS groups in terms of postoperative FACES pain scores and bleeding rates. The tonsillar fossa wound healing scores were statistically significantly higher for monopolar electrocautery tonsillectomy versus the TWS (p<0.001). Conclusions: Since the TWS is more expensive than monopolar electrocautery and use of the TWS did not confer any clear advantage over monopolar electrocautery for tonsillectomy in terms of postoperative pain, hemorrhage, and wound healing; monopolar electrocautery should be preferred over TWS for tonsillectomy operations.
