Guilherme de Araújo Almeida
This article reports the clinical case of a female patient with history of unsuccessful orthodontic treatment. She presented with Class III malocclusion, mandibular and maxillary constriction, anterior crossbite and facial asymmetry resulting from laterognathism triggered by hyperactivity of the condyle revealed by vertical elongation of the right mandibular ramus. Patient's treatment consisted of orthodontic mechanics and two orthognathic surgical interventions with satisfactory and stable outcomes. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), as part of the requirements for obtaining the BBO Diplomate title...

Corticosteroid injections are used as a nonoperative modality to combat acute inflammation when conservative treatments fail. As female patients are regularly seen by orthopedic physicians, it is essential to identify and understand potential sex-related side effects. The aim of this article is to examine available literature for sex-related side effects of orthopedic-related corticosteroid injections. Although the incidence is low, sex-related side effects, such as abnormal menstruation, lactation disturbances, facial flushing, and hirsutism, are associated with corticosteroid injections...

INTRODUCTION: The mandible consists of different segments, each of which possess its own specific characteristics regarding emergence, ossification during growth and pathologies. Orthodontists need to be very familiar with these developmental anomalies if they are to avoid failure in their orthopedic or orthodontic treatments and in order to understand the reasons for the lack of success of "conventional" treatments. Each segment must develop correctly if the mandible is to achieve optimal development and occupy a normal position within the cranio-facial complex...

Chondrocytes are the exclusive cells residing in cartilage and maintain the functionality of cartilage tissue. Series of biocomponents such as different growth factors, cytokines, and transcriptional factors regulate the mesenchymal stem cells (MSCs) differentiation to chondrocytes. The number of chondrocytes and dedifferentiation are the key limitations in subsequent clinical application of the chondrocytes. Different culture methods are being developed to overcome such issues. Using tissue engineering and cell based approaches, chondrocytes offer prominent therapeutic option specifically in orthopedics for cartilage repair and to treat ailments such as tracheal defects, facial reconstruction, and urinary incontinence...

Goldenhar syndrome (GS) is a development syndrome, characterized by incomplete development of the craniofacial region. The involvement is mainly unilateral; it varies from being mild to severe; and it can range from malocclusion and facial asymmetry to a more complex phenotype with complete absence of the mandibular ramus and temporomandibular joint. However, orthopedic symptoms of orofacial pain and dysfunction have not generally been considered as part of the symptom complex in GS cases. The case presented here is of a 15-year-old Caucasian patient, who was referred for evaluation because of bilateral pain in the masticatory muscles and temporomandibular joints...

Orthopedic correction of skeletal Class III malocclusion in a growing patient is crucial as it can circumvent future surgical procedures. Further, as surgery is done only at a later stage, early treatment helps to avoid the detrimental effects produced by the facial disfigurement on the patient's social life. This case report describes the treatment of a child aged 9 years 6 months who had a skeletal Class III malocclusion. The treatment plan involved the use of a reverse pull headgear (facemask) and multibracket appliance therapy resulting in successful correction of the malocclusion...

The influence of three-dimensional facial contour and dynamic evaluation decoding on factors of smile esthetics is essential for facial beauty improvement. However, the kinematic features of the facial smile contour and the contribution from the soft tissue and underlying skeleton are uncharted. Here, the cheekbone-maxilla contour and nasolabial fold were combined into a "smile contour" delineating the overall facial topography emerges prominently in smiling. We screened out the stable and unstable points on the smile contour using facial motion capture and curve fitting, before analyzing the correlation between soft tissue coordinates and hard tissue counterparts of the screened points...
