Computer-aided design and manufacturing technology applied to total nasal reconstruction

Abstract The principles of nasal reconstruction include the need to reconstruct three tissue layers, restore entire skin aesthetical units, and, possibly, replacement with like tissues. Computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies were applied two total reconstructions in male patients who underwent rhinectomy for cancer. Three-dimensional (3D) data obtained from computerized tomography (CT) scan-derived DICOM files (Digital Imaging Communications Medicine), this allowed us shape reconstructive nose order mimic native plan dimensions angles. A custom-made titanium plate was manufactured structure a bi-dimensional template forehead flap printed. layers: local flaps lining, structure, expanded skin. Forehead pedicle divided 3 weeks postoperatively under anesthesia an outpatient clinic, as well further minor refinements. 6-month post-operative CT scan compare result planned nose. No complications reported. superimposition demonstrated 92% match case 1 95% 2 between reconstructed one. is still most favorable option reconstruction, CAD technology allows implement planning makes procedure easier; moreover, use CAM desired naso-frontal angle. Level evidence: level V, therapeutic study.
