Abstract

Auricular epithesis is the most challenging in maxillofacial reconstruction. The advent of the digital technology in the field of the maxillofacial prosthesis ensures accuracy and precision. This paper highlights the case of a 34-year patient of an alleged road traffic accident with resultant in traumatic partial avulsion of the left ear. The data acquisition of the healthy ear was captured using a Computed Tomography Machine and mirrored using the Geomagic freeform Software to mirror the healthy ear into the defect area. The mirrored image was then processed to a watertight model for 3D printing. Stereolithography (SLA) was used to print the model followed by which the silicone epithesis was fabricated. This case report also explains about the various techniques to capture the data digitally and the several softwares that are available to process the data. Blending both analogue and digital method, an auricular epithesis can be made more lifelike, comfortable and functional thereby improving the quality of life of individuals with ear deformities.
