Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="hed23540-sec-0001" sec-type="section"> <title>Background</title> <p>Prototyping technologies for reconstructions consist of obtaining a 3‐dimensional model of the object of interest. Solid models are constructed by the deposition of materials in successive layers. The purpose of this study was to perform a double‐blind, randomized, prospective study to evaluate the efficacy of prototype use in head and neck surgeries.</p> </sec> <sec id="hed23540-sec-0002" sec-type="section"> <title>Methods</title> <p>Thirty‐seven cases were randomized into prototype and nonprototype groups. The following factors were recorded: the time of plate and locking screw apposition, flap size, time for reconstruction, and an aesthetic evaluation.</p> </sec> <sec id="hed23540-sec-0003" sec-type="section"> <title>Results</title> <p>The prototype group exhibited a reduced surgical time (43.7 minutes vs 127.7 minutes, respectively; <italic>p</italic> = .001), a tendency to reduce the size of the bone flap taken for reconstruction, and better aesthetic results than the group that was not prototyped.</p> </sec> <sec id="hed23540-sec-0004" sec-type="section"> <title>Conclusion</title> <p>The use of prototyping demonstrated a trend toward a reduced surgical time, smaller bone flaps, and better aesthetic results. © 2014 Wiley Periodicals, Inc. <italic>Head Neck</italic> 36: 1773–1782, 2014</p> </sec> </abstract>
