Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="hed23382-sec-0001" sec-type="section"> <title>Background</title> <p>The purpose of this study was to evaluate the efficacy of preoperative versus intraoperative mandibular contouring using rapid prototyping technology.</p> </sec> <sec id="hed23382-sec-0002" sec-type="section"> <title>Methods</title> <p>Ten patients requiring mandibular reconstruction had a preoperative mandibular plate contoured to a fabricated 3D mandibular model based on preoperative imaging. A traditional intraoperative plate was also contoured. Two surgeons blinded to the study compared the plates with respect to conformance, surface‐area contact, and best overall match. A cost–benefit analysis was then performed.</p> </sec> <sec id="hed23382-sec-0003" sec-type="section"> <title>Results</title> <p>The average time to contour was 867 ± 243 seconds and 833 ± 289 seconds for the preoperative and intraoperative plates, respectively (<italic>p</italic> = .83). Interobserver analysis revealed no statistically significant differences in conformance (<italic>p</italic> = .38) or surface area contact (<italic>p</italic> = .14). In 7 of 9 cases, the preoperative plate was selected for the final reconstruction. In 1 case, an intraoperative plate was not contoured because of the lateral extent of the tumor.</p> </sec> <sec id="hed23382-sec-0004" sec-type="section"> <title>Conclusion</title> <p>In cases of mandibular distortion secondary to disease, pathologic fracture or defects involving multiple mandibular subsites this method is particularly advantageous. © 2013 Wiley Periodicals, Inc. <italic>Head Neck</italic> 36: 828–833, 2014</p> </sec> </abstract>
