The purpose of this study was to compare the intraoperative outcomes and postoperative complications of patients experiencing transoral thyroidectomy vestibular approach (TOTVA) and conventional open thyroidectomy (COT). PUBMED, EMBASE, the Cochrane Central Register of Controlled Trials in the Cochrane Library, and Web of science expanded between January 2007 and November 2022 comparing TOTVA and COT was exhaustively searched. Fifteen non-randomized controlled studies involving 2955 patients were included. The results of meta-analyses indicated that TOTVA was associated with longer operative time (WMD, 66.86; 95%CI, 47.15-86.56; P < 0.00001), more blood loss (WMD, 2.83; 95%CI, 1.77-3.90; P < 0.00001), higher incidence of wound infection (OR, 5.62; 95%CI, 1.57-20.10, P = 0.008). There was no significant difference in terms of transient recurrent laryngeal nerve (RLN) palsy and other postoperative outcomes. In conclusion, TOTVA appears to be a feasible and safe approach for the treatment of patients with benign thyroid nodules and selected differential thyroid carcinomas just like the COT.
