The search was conducted from the databases\u2019 establishment to May 31, 2025. Operative time, intraoperative blood loss, number of central lymph node dissections, postoperative drainage volume, length of hospital stay, postoperative infection, hypoparathyroidism, perioperative recurrent laryngeal nerve injury, complication, hypocalcemia, subcutaneous ecchymosis, cough, trachyphonia, postoperative parathyroid hormone (PTH), postoperative blood calcium, pain score of Visual Analogue Scale (VAS), swallowing discomfort, hematoma, central lymph node dissection time, and satisfaction with cosmetic effects were subjected to meta-analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 15 studies were included in the meta-analysis. The meta-analysis included a group of 1,961 patients diagnosed with thyroid carcinoma. Within this cohort, 777 patients underwent endoscopic thyroidectomy via TOETVA, while 1,184 patients underwent endoscopic thyroidectomy via ETAA. Compared with ETAA, TOETVA yielded lower intraoperative bleeding volume [weighted mean difference (WMD = \u22121 mL, 95% confidence interval (CI): \u22123 to 0, p = 0.03], higher number of central lymph node dissections (WMD = 1.4, 95% CI: 0.3 to 2.3, p = 0.02), and higher satisfaction with cosmetic effects of the patients (WMD = 0.93, 95% CI: 0.42 to 1.43, p = 0.0004), but longer operative time (WMD = 17 min, 95% CI: 8 to 26, p = 0.0002). There was no statistically significant difference between the two groups regarding postoperative drainage volume (WMD = \u22126 mL, 95% CI: \u221217 to 5, p = 0.31), postoperative infection [odds ratio (OR) = 1.43, 95% CI: 0.47 to 4.43, p = 0.53], perioperative recurrent laryngeal nerve injury (OR = 0.62, 95% CI: 0.30 to 1.28, p = 0.20), hypocalcemia (OR = 0.88, 95% CI: 0.40 to 1.91, p = 0.74), swallowing discomfort (OR = 0.83, 95% CI: 0.24 to 2.95, p = 0.78), hypoparathyroidism (OR = 0.47, 95% CI: 0.18 to 1.18, p = 0.11), and hospitalization time (WMD = 0.03 days, 95% CI: \u22120.13 to 0.19, p = 0.71).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The findings indicated that both TOETVA and ETAA demonstrated safe and reliable clinical efficacy.
