Laser TE has been suggested as an alternative to cold steel dissection, although its efficacy and safety for the surgical treatment of RAT remain unclear. Therefore, we conducted a systematic review and meta\u2010analysis comparing laser TE to cold steel dissection TE in patients with RAT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We systematically searched PubMed, Embase, and Cochrane Central for eligible studies. Outcomes of interest were intraoperative blood loss, operation time, quality of life, postoperative pain, and postoperative hemorrhage. Subgroup and sensitivity analyses were performed. RStudio v4.1.0 and Review Manager v5.4 were used for statistical analysis. A prospective protocol was registered in PROSPERO (CRD42024533742).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Nine studies, including six randomized trials, met eligibility criteria, comprising 612 patients with RAT. In total, 1224 tonsils were excised; 612 (50%) were submitted to laser TE, and the remaining to cold steel dissection. Laser was associated with lower intraoperative blood loss (mean difference [MD] \u221235.89; 95% confidence interval [CI] [\u221253.08, \u221218.71]; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01; <jats:italic>I<\/jats:italic>\u00b2\u2009=\u2009100%) and operation time (MD \u221210.46; 95% CI [\u221216.63, \u22124.29]; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01; <jats:italic>I\u00b2<\/jats:italic>\u2009=\u200999%).
