Background: We compared two systematic reviews, one focusing on transoral video-assisted thyroidectomy (TOVAT) and the other on minimally invasive video-assisted thyroidectomy (MIVAT), to highlight the pros and cons that can determine the choice of one or the other procedure. Materials and Methods: PubMed, Scopus and ISI Web of Science databases were searched for relevant articles published from 2000 to June 2018. Both searches were performed using the same keywords. All articles describing human surgical case series of any size were included, while the following were excluded: articles published in languages other than English, case reports, reviews, early cadaver and animal studies and old reports of cases now included in more recent works. Application of the above selection criteria yielded 151 articles on TOVAT and 246 on MIVAT. Of these, 34 articles were selected for inclusion in the present study: 17 for the TOVAT group and 17 for the MIVAT group. The comparison was made considering the most common variables used in evaluating thyroid surgery procedures. The statistical methods used were Cohen's delta, Student's t-test and the non-parametric Mann-Whitney U-test. Results: The variable 'operative time' was found to show a very large effect size, and 'hospital stay' also differed significantly between the MIVAT and TOVAT groups. Conclusions: TOVAT and MIVAT should not be considered in competition with each other, but seen simply as alternative choices. Both appear to be safe methods, comparable in terms of post-operative complications, although the main reason for using TOVAT seems to be purely aesthetic.
