Total thyroidectomy (TT) has historically been the primary treatment, but current guidelines recommend hemithyroidectomy (HT) for select low-risk cancers; however, the risk-benefit ratio of the 2 operations is incompletely characterized.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To compare surgical complication rates between TT and HT for PTMC treatment.<\/jats:p>\n <\/jats:sec>\n \n Data Sources<\/jats:title>\n SCOPUS, Medline via the PubMed interface, and the Cochrane Central Register of Controlled Trials (CENTRAL); through January 1, 2021, with no starting date restriction. Terms related to papillary thyroid carcinoma and its treatment were used for article retrieval. This meta-analysis used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline and was written according to the Meta-analysis of Observational Studies in Epidemiology (MOOSE) proposal.<\/jats:p>\n <\/jats:sec>\n \n Study Selection<\/jats:title>\n Original investigations of adults reporting primary surgical treatment outcomes in PTMC and at least 1 complication of interest were included. Articles evaluating only secondary operations or non\u2013open surgical approaches were excluded. Study selection, data extraction, and risk of bias assessment were performed by 2 independent reviewers and conflicts resolved by a senior reviewer.<\/jats:p>\n <\/jats:sec>\n \n Data Extraction and Synthesis<\/jats:title>\n Pooled effect estimates were calculated using a random-effects inverse-variance weighting model. Studies that directly compared outcomes between HT and TT were considered in a weighted meta-analysis for determination of effect sizes.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n Cancer recurrence and site, mortality (all-cause and disease-specific), vocal fold paralysis, hypoparathyroidism, and hemorrhage\/hematoma. Risk of bias was assessed using the McMaster Quality Assessment Scale of Harms scale.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n In this systematic review and meta-analysis, 17 studies were analyzed and included 1416 patients undergoing HT and 2411 patients undergoing TT (HT: pooled mean [SD] age, 47.0 [10.0] years; 1139 [84.6%] were female; and TT: pooled mean [SD] age, 48.8 [10.0] years; 1671 [77.4%] were female). Five studies directly compared outcomes between HT and TT, 5 reported solely on HT outcomes, and 7 reported solely on TT outcomes. Patients undergoing HT had significantly lower risk of temporary vocal fold paralysis compared with patients undergoing TT (2.0% vs 4.2%) (weighted risk ratio [RR], 0.4; 95% CI, 0.2-0.7), temporary hypoparathyroidism (2.2% vs 21.3%) (weighted RR, 0.1; 95% CI, 0.0-0.4), and permanent hypoparathyroidism (0% vs 1.8%) (weighted RR, 0.2; 95% CI, 0.0-0.8). Contralateral lobe malignant neoplasm recurrence was 2.4% in the HT group, while no such events occurred in the TT group. Hemithyroidectomy was associated with a higher overall recurrence rate compared with TT (3.9% vs 1.3%) (weighted RR, 2.8; 95% CI, 1.4-5.7), but there was no difference in recurrence in the thyroid bed or neck.<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n The results of this systematic review and meta-analysis help characterize current knowledge of the risk-benefit ratio of HT vs TT for treatment of PTMC and provide data that may have utility for patient counseling surrounding treatment decisions.<\/jats:p>\n
