FLOWCHART OF FREE SOFTWARE METHODOLOGY FOR ANALYSIS OF FACIAL ASYMMETRY AND FORMATION OF HISTOGRAM MAPS AS A SURGICAL GUIDE

Surgical treatment of facial asymmetry poses challenges not only in execution but also in evaluation and planning. Image analysis methods bring advantages and disadvantages compared to subjective forms. Virtual planning technology using three-dimensional images is an alternative, though underutilized due to the cost of commercial software licenses. By using free software such as Blender® and CloudCompare®, students and healthcare professionals, including plastic surgeons, have access to an objective and effective low-cost method for pre-surgical evaluation and planning. This study established a methodology owchart for analyzing facial asymmetry and constructing a histogram map as a surgical guide.
