Virtual and traditional surgical planning in orthognathic surgery - systematic review and meta-analysis.

Abstract

Traditional surgical planning (TSP) and virtual surgical planning (VSP) have been used in bimaxillary osteotomy planning. The time is taken in the planning and operating stages, and the working/doctor/total time of either approach are useful determinants of the efficiency of the operating method and quality of care. This systematic review and meta-analysis examined if VSP has a comparative advantage over TSP in the bimaxillary osteotomy. Cochrane Library, PubMed, EMBASE, and Google Scholar were used as databases to collect studies that met the outlined inclusion criteria based on PRISMA. Eight of 759 studies were considered to meet the eligibility criteria, and six fit for meta-analysis. The findings demonstrated significant VSP advantage over TSP in planning time (Z = 3.97 (p < 0.00001), WMD = -5.29 (CI -7.90 to -2.68)). While more time-efficient than TSP, the difference with VSP was not significant during surgery (Z = 0.44 (p = 0.66), WMD = -0.10 (CI -0.51 to 0.34)). The study used random effects due to the high I
