Lee YC, Hsin LJ, Lin WN, et al. - Researchers conducted this systematic review and meta-analysis to compare temperature-controlled surgical instruments (TCSIs) with electrocautery (EC) with regard to the intraoperative and postoperative parameters of tonsillectomy. This meta-analysis involved 11 studies with a total of 629 unique individuals (mean ages ranged from 16 to 55 years). Findings suggested an association of TCSIs with significantly reduced pain on the first day after tonsillectomy compared with EC. Comparable were the rates of overall bleeding, primary bleeding, secondary bleeding, major bleeding, and minor bleeding between TCSIs and EC. In addition, intraoperative blood loss and operative time exhibited no significant intergroup differences. According to personal experiences, preferences, and cost-effectiveness criteria, surgeons may consider using these modern instruments.
