“…In his four books on human proportion, Albrecht Duerer used exactly symmetrical schemes for his depicted faces based on the data of his own anthropometric studies [31]. However, with more sophisticated measuring methods, it became obvious that a smaller degree of facial asymmetry is physiological, but if a certain threshold of asymmetry is exceeded, the face will be perceived as disfigured [32,33]. To determine whether a condition should be considered to be within the "normal range" or pathological, it became necessary to define methods to measure asymmetry in an objective and reproducible manner.…”

Animal bodies in general and faces in particular show mirror symmetry with respect to the median-sagittal plane, with exceptions rarely occurring. Bilateral symmetry to the median sagittal plane of the body also evolved very early. From an evolutionary point of view, it should therefore have fundamental advantages, e.g., more effective locomotion and chewing abilities. On the other hand, the recognition of bilaterally symmetric patterns is an important module in our visual perception. In particular, the recognition of faces with different spatial orientations and their identification is strongly related to the recognition of bilateral symmetry. Maxillofacial surgery and Dentistry affect effective masticatory function and perceived symmetry of the lower third of the face. Both disciplines have the ability to eliminate or mitigate asymmetries with respect to form and function. In our review, we will demonstrate symmetric structures from single teeth to the whole face. We will further describe different approaches to quantify cranial, facial and dental asymmetries by using either landmarks or 3D surface models. Severe facial asymmetries are usually caused by malformations such as hemifacial hyperplasia, injury or other diseases such as Noma or head and neck cancer. This could be an important sociobiological reason for a correlation between asymmetry and perceived disfigurement. The aim of our review is to show how facial symmetry and attractiveness are related and in what way dental and facial structures and the symmetry of their shape and color influence aesthetic perception. We will further demonstrate how modern technology can be used to improve symmetry in facial prostheses and maxillofacial surgery.

“…Uma boa harmonia e simetria facial se mostra como um caminho para boas relações entre os indivíduos e melhor qualidade de vida (Heydenrich, 2020). Contudo, deve-se observar o grau da desarmonia facial, quando existente, e considerar os possíveis futuros problemas estéticos e funcionais que podem surgir ao longo da vida (Kobus, Kobus-Zalésna, 2017;Medeiros et al, 2020).…”

Introdução: A harmonia na estética facial se mostrou como um dos principais aspetos físicos para uma melhor relação entre os indivíduos. Em contrapartida, a assimetria pode fazer com que indivíduos apresentem consequências psicológicas e estéticas durante a vida. Fatores ligados à maturação e morte celular faz com que tenha o decaimento dos tecidos faciais, afetando o terço médio e inferior a face. Por meio de uma minuciosa avaliação clínica assegura-se o tratamento das desarmonias faciais com a utilização de preenchedores injetáveis a fim de harmonizar o perfil dos pacientes. Objetivo: Relatar o caso clínico de uma paciente do sexo feminino, leucoderma, 38 anos, com assimetria labial e descrever os procedimentos que foram realizados com a utilização de preenchedores faciais no terço médio da face para correção de decaimento labial. Relato do caso: Paciente do sexo feminino, 38 anos, chegou ao consultório particular com queixa de assimetria labial do lado esquerdo. Após detalhada avaliação clínica e obtenção de imagens para análise facial, observou-se uma assimetria no lado esquerdo. Para início do tratamento, foram propostos bioestimuladores injetáveis de hidroxiapatita de cálcio (Radiesse) e preenchimento labial em iguais pontos e proporções em ambos os lados. A paciente foi alertada que no primeiro momento a assimetria labial seria mantida, pois para complementação do tratamento foram definidos pontos de estruturação no terço médio com maior concentração no lado esquerdo da face. Ao finalizar o tratamento proposto na região de terço médio, notou-se uma correção da assimetria labial.

“…In patients with lesions in the head and neck region, these gradually growing lesions may lead to perceived esthetic issues, particularly facial asymmetry [ 4 ]. Of note, interventions for facial asymmetry are recommended in the early stages of lesion growth, as correction in more advanced stages often presents further complications [ 5 ].…”

Ultrasound-Guided Moving Shot Radiofrequency Ablation of Benign Soft Tissue Neoplasm

et al. 2021

Background and Objective: To evaluate the effectiveness of radiofrequency ablation (RFA) using the moving-shot technique for benign soft tissue neoplasm. Materials and Methods: This retrospective study reviewed eight patients with benign soft tissue neoplasm presenting with cosmetic concerns and/or symptomatic issues who refused surgery. Six patients had vascular malformation, including four with venous malformation and two with congenital hemangioma. The other two patients had neurofibroma. All patients underwent RFA using the moving-shot technique. Imaging and clinical follow-up were performed in all patients. Follow-up image modalities included ultrasound (US), computed tomography (CT), and magnetic resonance (MR) imaging. The volume reduction ratio (VRR), cosmetic scale (CS), and complications were evaluated. Results: Among the seven patients having received single-stage RFA, there were significant volume reductions between baseline (33.3 ± 21.2 cm3), midterm follow-up (5.1 ± 3.8 cm3, p = 0.020), and final follow-up (3.6 ± 1.4 cm3, p = 0.022) volumes. The VRR was 84.5 ± 9.2% at final follow-up. There were also significant improvements in the CS (from 3.71 to 1.57, p = 0.017). The remaining patient, in the process of a scheduled two-stage RFA, had a 33.8% VRR after the first RFA. The overall VRR among the eight patients was 77.5%. No complications or re-growth of the targeted lesions were noted during the follow-up period. Of the eight patients, two received RFA under local anesthesia, while the other six patients were under general anesthesia. Conclusions: RFA using the moving-shot technique is an effective, safe, and minimally invasive treatment for benign soft tissue neoplasms, achieving mass volume reduction within 6 months and significant esthetic improvement, either with local anesthesia or with general anesthesia under certain conditions.
