“…Sixteen records evaluated the accuracy of PSI for the maxilla [ 13 , 31 , 32 , 33 , 34 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ], out of which eight exclusively focused on non-segmental Le Fort I procedures [ 31 , 32 , 34 , 36 , 38 , 43 , 45 , 46 ] and two on non-segmental Le Fort I procedures in conjunction with the accuracy of PSI for mandibular osteotomies [ 13 , 39 ]. Six studies included mixed single and segmental Le Fort I osteotomies [ 33 , 37 , 40 , 41 , 42 ].…”

“…The only subset that had sufficient data for a meta-analysis comprised those studies employing single Le Fort I osteotomies exclusively. The studies reporting absolute values were analyzed [ 32 , 34 , 36 , 39 , 43 , 45 ]. A stratification of the meta-analysis on absolute and signed values was done to allow correct interpretation of the estimates on two studies [ 13 , 46 ].…”

“…The outcome variables and the antero-posterior, transversal and vertical error measurements were registered. An analysis was also conducted on the subset of studies that included pitch, roll and yaw error measurements [ 34 , 36 , 39 , 43 , 45 , 46 ]. This analysis was also stratified, with a stratum for the studies reporting signed values separate from the rest.…”

“…It should be noted that surface-based registration (SBR) provides an alternative method to VBR for the 3D assessment of the surgical accuracy and stability of orthognathic surgery, which has been applied in several of the included studies in the present systematic literature review [ 13 , 29 , 30 , 31 , 32 , 35 , 36 , 40 , 43 , 45 , 46 , 47 , 48 ]. Surface-based registration aligns two 3D surfaces using the iterative closest point algorithm [ 49 ], and SBR has been shown to be a reproducible method [ 50 , 51 ].…”

This systematic review aimed to determine the accuracy/stability of patient-specific osteosynthesis (PSI) in orthognathic surgery according to three-dimensional (3D) outcome analysis and in comparison to conventional osteosynthesis and computer-aided designed and manufactured (CAD/CAM) splints or wafers. The PRISMA guidelines were followed and six academic databases and Google Scholar were searched. Records reporting 3D accuracy/stability measurements of bony segments fixated with PSI were included. Of 485 initial records, 21 met the eligibility (566 subjects), nine of which also qualified for a meta-analysis (164 subjects). Six studies had a high risk of bias (29%), and the rest were of low or moderate risk. Procedures comprised either single-piece or segmental Le Fort I and/or mandibular osteotomy and/or genioplasty. A stratified meta-analysis including 115 subjects with single-piece Le Fort I PSI showed that the largest absolute mean deviations were 0.5 mm antero-posteriorly and 0.65° in pitch. PSIs were up to 0.85 mm and 2.35° more accurate than conventional osteosynthesis with CAD/CAM splint or wafer (p < 0.0001). However, the clinical relevance of the improved accuracy has not been shown. The literature on PSI for multi-piece Le Fort I, mandibular osteotomies and genioplasty procedure is characterized by high methodological heterogeneity and a lack of randomized controlled trials. The literature is lacking on the 3D stability of bony segments fixated with PSI.

“…Midface correction was commonly performed during adulthood (78). The use of patient specific cutting guides in Le Fort I surgeries increased accuracy compared to the use of a surgical wafer in a cohort of 18 patients with CFM (79). No ideal surgical treatment protocol was identified due to the lack of sufficient outcome data.…”
