Special Issue Information

Dear Colleagues,

Symmetry relates to the harmony of propotions and is a pervasive property of nature. It is ubiquitous, essential, compact, and aesthophysiological in human anatomy and living organisms. Significant asymmetry of a structure in medical images can usually indicate the presence of pathology. Extensive studies and medical applications exist to fortify the concept of symmetry as a general feature of objects. For example, facial symmetry is an important metric to assess attractiveness and can serve as a tool to evaluate the effectiveness of plastic sugery. In assessing skeletal age, only one hand and wrist is usually needed as the skeletal maturation of human hands and wrists exhibits bilateral symmetry. The bilateral symmetry of bones suggests using intact/uninjured bones as a template to reconstruct the contralateral bone in orthopedics. Studies showing that the human pelvis exhibits strong bilateral symmetry across the sagittal plane have been applied for fracture reconstruction.

In addition to subjective perception, quantitative measurements of symmetry are important to improve semi-automatic and/or automatic analysis of medical images. Reproducible identification of the sagittal plane or the three-dimensional coordinates of the object of concern are among the critical processes. Degrees of asymmetry can be computed using landmark-based, lankmarkless, contour-based, mesh-feature-based, etc., approaches. Recent advances in machine/deep learning and artificial intelligence have expanded the horizon of medical image processing. The corresponding techniques are expected to have great impacts on the efficacy of symmetry-based medical imaging.  

The aim of this Special Issue is to highlight the latest developments in the discipline of medical image processing. Our goal is to explore the merits of symmetrical features in medical images in the hope of better diagnosing symptoms, evaluating their significance, and performing treatments for the patients.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Facial symmetry affects the perception of facial beauty. Overall, facial harmony with an appropriate facial proportion and satisfactory midline facial symmetry are crucial factors for facial attractiveness. The role of orthodontists in correcting facial asymmetry begins with providing suitable diagnosis of the condition and identifying patients’ expectations. Through a thorough, subjective clinical evaluation of dentofacial asymmetry, the procedures for the surgical orthodontic management of facial asymmetry are discussed. The aim of this clinical review is to provide information on surgical indications for facial asymmetry, optimal treatment goals, presurgical orthodontic preparation, the surgery-first approach, three-dimensional (3D) surgical simulation, postsurgical orthodontic finishing, and treatment outcome evaluation. A comprehensive 3D diagnosis with appropriate planning, accurate transference of surgical simulation to real surgery, slight overcorrection, periodic assessment of treatment outcomes, and awareness of treatment limitations are essential to improve treatment outcomes of facial asymmetry.
