PurposeThe aim of this study was to systematically review methods used for assessing the accuracy of 3D virtually planned orthognathic surgery, in an attempt to reach an objective assessment protocol that could be universally used.MethodsA systematic review of the current available literature, till 12/9/2016, was conducted using PubMed as the primary search engine. Secondary searches were performed in the Cochrane database, Clinical trial registries, Google scholar, EMBASE and a bibliography search. Included articles should state clearly that 3D virtual planning was used and accuracy assessment performed, along with validation of the planning and/or assessment method. Descriptive statistics as well as quality assessment of included articles were also performed.ResultsInitial search yielded 1461 study. Only 7 studies were included in the current review. There was found to be an important variability as regards methods used for i) accuracy assessment of virtually planned orthognathic surgery or ii) validation of the used tools. Included studies were found to be of moderate quality, reviewers agreement regarding quality was calculated to be 0.5 using Cohen's Kappa test.ConclusionBased on the findings of the current review, it is evident that the literature lacking consensus regarding the accuracy assessment. Hence, a protocol was suggested for accuracy assessment of the virtually planned orthognathic surgery with the least margin of error.
