3D image analysis of nasal orbit fossa through a laser scanner: a new method and application of 3D image / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>This study was to introduce the method for obtaining accurate 3D data of soft tissues using a 3D scanner under non-contact condition and the standard 3D measurement of the nasal orbit fossa for plastic surgery.</p><p><b>METHODS</b>A 3D laser scanner and the Geomagic software were used to obtain the standard facial contour of 30 Chinese people. The nasal orbit fossa, as the feature of beauty, was measured and the data were analyzed.</p><p><b>RESULTS</b>3D measurement exhibited the three-dimensional facial shape at every meaningful angle, with the advantages of high precision of 0.01 mm. We determined the lowest point and described the 3D feature of the nasal orbit fossa.</p><p><b>CONCLUSIONS</b>This method can illustrate the relation of the nasal orbit fossa and the surrounding structure. It is a new approach to facilitate preoperative plans, operation simulation and postoperative evaluation.</p>
