Time matters - differences between virtual surgical planning and conventional planning in cranio-maxillofacial surgery: a systematic review and meta-analysis

• The aim of the study was to assess if there is a time difference (operative time, ischemia time, planning time and hospitalization) between virtual surgical planning (VSP) and conventional planning in cranio-maxillofacial surgery (CMF). An electronic search was performed in June 2018. Studies comparing time difference between VSP and traditional planning were included. A meta-analysis was undertaken to demonstrate the difference between the groups regarding operative time, ischemia time and hospitalization duration for CMF reconstruction. 27 publications were included, with 524 patients in the VSP group and 770 in the control group. Most studies reported on mandible/maxilla reconstruction and the meta-analysis showed a decreased operative time for the VSP group with a mean difference of -84.61 min (95%CI -106.77, -62,45, p<0.00001). Ischemia time was also decreased, with a mean difference of -36.14 min (95% confidence interval -50.57, -21.71, p<0.00001). This systematic review and meta-analysis suggests that VSP is shortening the operation time and ischemia time for reconstructive CMF surgery. VSP also seems to shorten the preoperative planning time for orthognathic surgery.
