Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="rcs1557-sec-0001" sec-type="section"> <title>Background</title> <p>The reconstruction of zygoma is a challenge with regard to aesthetic and reconstructive demands.</p> </sec> <sec id="rcs1557-sec-0002" sec-type="section"> <title>Methods</title> <p>Pre‐operative CT data were imported into specific surgical planning software. The mirror‐imaging technique was used. A surgical guide transferred the virtual surgery plan to the operation site, whereby it fitted uniquely to the iliac donor site. A postoperative CT scan was obtained for comparing the actual postoperative graft position and shape with the pre‐operative virtual simulation.</p> </sec> <sec id="rcs1557-sec-0003" sec-type="section"> <title>Results</title> <p>A mean difference of 0.71 mm (SD ± 1.42) for the shape analysis and 3.53 mm (SD ± 3.14) for the graft position was determined. The calculation of the closest point distance showed a surface deviation of &lt; 2 mm for the shape analysis with 83.6% of values and for the graft position with 35.7% of values.</p> </sec> <sec id="rcs1557-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Virtual surgical planning is a suitable method for zygoma reconstruction with vascularized iliac crest bone graft, with good accuracy for restoring the three‐dimensional anatomy.
