Facial tissue loss presents with multiple functional and psychological problems. Its rehabilitation can improve the physical, mental and social well being of the patient. In conditions where surgical corrections are not favourable, the prosthetic approach to rehabilitate the missing structures can solve the problems, with added advantages of having complete control over colour and morphological outcome to match the surrounding skin and the counter lateral part. This case report describes the rehabilitation of a patient with the right auricular defect who was treated with a silicon auricular prosthesis and few ornaments were used as the retentive aids.

Microtia profoundly affects patients' appearance and psychological well-being. Tissue engineering ear cartilage scaffolds have emerged as the most promising solution for ear reconstruction. However, constructing tissue engineering ear cartilage scaffolds requires multiple passaging of chondrocytes, resulting in their dedifferentiation and loss of their special phenotypes and functions.

Background: Facial prosthetics are an important means to rehabilitate patients with congenital or acquired facial defects. However, with a time-consuming manual workflow and workforce shortage, access to facial prosthetics is limited in Australia and worldwide, especially for rural and remote patients. Optical 3D scanning has been increasingly integrated in digitizing data.

Objective: For full expansion of ear reconstruction, the stability of a cartilage framework is very important. However, most techniques for framework fabrication focus on three-dimensional structure and adequate projection. Few studies are available on improving the stability of the reconstructed framework.

Facial impression methods have been used to fabricate auricular prostheses; however, deformation due to the weight of the impression material remains. This study aimed to investigate the accuracy of auricular three-dimensional (3D) data obtained using a 3D optical extraoral scanner and an intraoral scanner compared with that of a conventional facial impression method. Six auricles were digitized using an extraoral scanner with and without a reference board around the auricle and an intraoral scanner.

In this study, the optimal engraving parameters were determined through the analysis of scanning electron microscopy (SEM) data, as follows: a laser power density of 5.5 × 10 W/cm, an irradiation rate of 0.1 mm/s, a well radius of 60 μm, a distance between well centers of 200 μm, and a number of passes for each well of 20.
