Computer-aided tissue expansion 3D profilometry and surgery planning system / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To develop and evaluate the computer-aided system in measurement of expanded skin and preoperative planning.</p><p><b>METHODS</b>Stereophotogrammetric technique was used to gain the 3D image-pairs, from which the contours of the expanded sites were restored. The 3D surface data were provided to the specially developed "computer-aided tissue expansion 3D profilometry and surgery planning system", to calculate the expansion area and help the preoperative design.</p><p><b>RESULTS</b>The system has been applied clinically in 16 tissue expansion sites of 11 patients with fairly good results since March 1999. Compared with the traditional method, this system is accurate, repeatable and feasible.</p><p><b>CONCLUSION</b>This technique is useful and promising for improving the operation of tissue expansion.</p>
