Methods： Electronic databases including Cochrane Controlled Trials Register, EMbase, Medline, SCI Expanded-ISI, NTIS, SIGLE and CNKI were searched. Eligible studies were randomized controlled trials which compared the incidence of postoperative complications of TT with ST/NTT for treating BMNG. Data extraction was using predefined data fields and assessment of methodological quality with the GRADE approach. A ManteI-Haenszel random-effects model was used and the effect sizes were expressed by using relative risks and 95% confidence intervals. Results： Four studies including 881 participants that met inclusion criteria were analyzed. Compared with ST/NTT, TT was associated with increased risk of transient RLNI （recur- rent laryngeal nerve injuries） （relative risk 2.18, 95% confidence interval 1.08 to 4.42; P 〈 0.05） and transient hypocalcemia （3.79, 1.64 to 8.77; P 〈 0.05）, but there were no statistically significant differences in permanent RLNI （1.36, 0.31 to 6.02; P 〉 0.05） and permanent hypocalcemia （2.37, 0.35 to 15.97; P 〉 0.05）. The quality of evidence for each individual outcome was ultimately rated as moderate （permanent RLNI and permanent hypocalcemia）, low （transient RLNI and transient hypocalce- mia）. Conclusion： For treating BMNG with thyroidectomy, there were no statistically significant differences in postoperative complications between TT and ST/NTT on a long view.展开更多
