Accuracy of Mandibular Reconstruction with a Vascularised Iliac Flap Using 3D Templates: a Systematic Review.

OBJECTIVE
To conduct a systemic review for guidance regarding the application of templates in mandibular reconstruction with vascularised iliac flaps.


METHODS
By searching PubMed, EMBASE and the Cochrane Library and collecting relevant literature, information about the types and accuracy of templates was extracted. Data relating to surgical time were also included for further analysis.


RESULTS
Eight studies were included. The data analysis showed that the accuracy of operations with templates was higher than that of conventional surgery. The mean deviation was between 0.70 and 3.72 mm. The operational time was shortened to 314.4 minutes and the graft ischemic time was reduced to 15.6 to 26.8 minutes. Application of functional or specifically designed templates can improve the accuracy and shorten surgical time.


CONCLUSION
Templates can increase the accuracy and efficiency of mandibular reconstruction with vascularised iliac flaps, which will benefit patients' prognosis and subsequent functional restoration. Further studies should be conducted into application of templates to improve the accuracy of reconstructions.
