Purpose - The purpose of this paper is to propose a template-based framework for nasal prosthesis fabrication using a 3D areal scanner and a CT scanner. Design/methodology/approach - Use of a self-designed 3D areal scanner enables acquisition of accurate data describing the patient's face. Patients with nasal defects have no organization for reference, but the template-based model construction method can ensure successful building of the outer surface of the nasal prosthesis. Since the areal scanner has some difficulties acquiring data for concave areas, preoperative CT data are used to provide concave information, enabling construction of the inner surface for the nasal prosthesis. The combined inner and outer surfaces are used to generate the completed nasal prosthesis. Findings - The results showed that the nasal prosthesis fits the patient's appearance well. Clinical applications confirmed that this framework is attractive and has the potential desired nasal prosthesis in daily clinical practice. Practical implications - The results of this study improve the fabrication accuracy of nasal prostheses. The construction and development technique employs a nasal digital library, 3D areal scanning data and CT scanning data. This technique facilitates fabrication of precise nasal prostheses while helping the patients predict the effect before the prosthesis is manufactured. Originality/value - This template-based framework has strong potential for clinical applications because of its advantages over other methods in terms of accuracy, speed, safety, and cost. © Copyright - 2013 Emerald Group Publishing Limited.

Purpose - The purpose of this paper is to propose an imperfect symmetry transform framework for orbital prosthesis modelling. Design/methodology/ approach - Current models of patients with orbital defects have imperfect symmetries. Commonly used methods, such as principal component analysis (PCA) or iterative closest points algorithm (ICP), do not detect perfect symmetries and therefore produce poor results. The authors propose an improved ICP algorithm based on the M-estimator, which can remove outliers from the optimization and detect incorrect symmetry. Using this algorithm, the mid-facial plane of a patient's facial model can be precisely obtained despite perturbation of the facial shape due to the defect. Findings - The results showed that the orbital prosthesis fitted well to the patient's appearance. Clinical applications confirmed that this framework is attractive and has the potential for use in creating desired orbital prostheses or other bilateral maxillofacial prostheses in daily clinical practice. Practical implications - The method described in this report will improve the fabrication accuracy of orbital prostheses or other bilateral maxillofacial prostheses. Originality/value - This imperfect symmetry transform framework has great potential for use in clinical applications because of its advantages over other existing methods in terms of accuracy. © Emerald Group Publishing Limited.
