For papillary thyroid carcinoma (PTC) surgery requiring total thyroidectomy and central lymph node dissection, it is controversial whether the bilateral axillo-breast approach robotic thyroidectomy (BABA RT) can replace the open thyroidectomy (OT). To evaluate the efficacy of two surgical approaches. Relevant literatures were searched from PubMed, EMBASE and Cochrane Library. Studies comparing two surgical approaches and meeting the inclusion criteria were selected. Compared with OT, BABA RT showed a similar incidence of postoperative complications, including recurrent laryngeal nerve palsy, hypocalcemia, hypoparathyroidism, bleeding, chyle leakage and incision infection, as well as number of retrieved central lymph nodes and postoperative total dose of radioactive iodine. However, BABA RT involved longer operative time (weighted mean difference [WMD] 72.62, 95% confidence interval [CI] 48.15-97.10, P < .00001) and higher postoperative stimulated thyroglobulin level ([WMD] 0.12, 95% [CI] 0.05-0.19, P = .0006). The efficacy of BABA RT is basically similar to OT in this meta-analysis, but the higher postoperative stimulated thyroglobulin level attracts our attention. Longer operative time requires us to shorten. Randomized clinical trials with large samples and longer follow-up data are still essential to further demonstrate the value of the BABA RT.
