“…The main drawback, however, is related to the computational time for determining the symmetry line, mostly depending on the number of slices used to partition the 3D data. To enforce the symmetry line detection and, at the same time, to reduce the computational time, adaptive sections-based methods presented in [18,19] can be the best solution. 3D position of landmarks manually acquired.…”

Versatile, cheap and non-invasive 3D acquisition techniques have received attention and interest in the field of biomedicine in recent years as the accuracy of developed devices permits the acquisition of human body shapes in detail. Interest in these technologies derives from the fact that they have the potential to overcome some limitations of invasive techniques (CT, X-rays, etc.) and those based on 2D photographs for the acquisition of 3D geometry. However, the data acquired from the 3D scanner cannot be directly used but need to be processed as they consist of 3D coordinates of the acquired points. Therefore, many researchers have proposed different algorithms which recognise the shape of human body and/or its features when starting from a 3D point cloud. Among all possible human body features to be evaluated, symmetry results the most relevant one. Accordingly, this survey systematically investigates the methods proposed in the literature to recognise 2D symmetry by the symmetry line and bilateral symmetry by the symmetry plane. The paper also analyses qualitative comparisons among the proposed methods to provide a guide for both practitioners and researchers.

“…To overcome the restrictions of horizontal slicing methods and allow the analysis of asymmetric postures that are widely assumed by workers in their workplaces, Di Angelo et al [17,18] proposed a new method, called "nonerected posture approach (NEPA)", relying on an adaptive approach.…”

“…On the other hand, 3D scanning enables the direct acquisition of three-dimensional data of the outer anatomical surface without the use of ionizing radiation, non-invasively, and at low cost [38]. In the medical field, several scientific studies report the use of 3D scanners to acquire anatomical data for the construction of orthoses [39] or medical devices [40], but also for diagnostic purposes [41] or maxillofacial reconstruction planning [41,42,43,44].…”

Ear Reconstruction Simulation: From Handcrafting to 3D Printing

Microtia is a congenital malformation affecting one in 5000 individuals and is characterized by physical deformity or absence of the outer ear. Nowadays, surgical reconstruction with autologous tissue is the most common clinical practice. The procedure requires a high level of manual and artistic techniques of a surgeon in carving and sculpting of harvested costal cartilage of the patient to recreate an auricular framework to insert within a skin pocket obtained at the malformed ear region. The aesthetic outcomes of the surgery are highly dependent on the experience of the surgeon performing the surgery. For this reason, surgeons need simulators to acquire adequate technical skills out of the surgery room without compromising the aesthetic appearance of the patient. The current paper aims to describe and analyze the different materials and methods adopted during the history of autologous ear reconstruction (AER) simulation to train surgeons by practice on geometrically and mechanically accurate physical replicas. Recent advances in 3D modelling software and manufacturing technologies to increase the effectiveness of AER simulators are particularly described to provide more recent outcomes.
