TRABAJO INVESTIGACIÓN RESUMENObjetivo: Describir las características craneofaciales, dentoalveolares, de tejido blando, vía aérea y el patrón de actividad muscular determinadas a través de los estudios cefalométricos y electromiográficos de individuos incompetentes labiales y con presencia de anomalías dentomaxilares de 7 a 12 años de edad. Materiales y método: Cuarenta y seis participantes con incompetencia labial fueron sometidos a una toma de radiografía lateral de perfil para el análisis cefalométrico. Para el estudio electromiográfico se consideró el patrón de actividad de los músculos Orbicular superior de los labios, orbicular inferior de los labios y temporal anterior en funciones: reposo, fonoarticulación, deglución, máximo apriete labial. Resultados: Se observó clase II esqueletal y molar, retrusión mandibular, biprotrusión incisal, biprotrusión labial, disminución de vía aérea superior. La mayor actividad muscular fue observada en máximo apriete labial. Conclusión: Los niños y niñas con incompetencia labial y anomalías dentomaxilares presentan alteraciones en las características craneofaciales, dentoalveolares, de tejido blando, vía aérea y actividad muscular determinadas a través de los estudios cefalométricos y electromiográficos. PALABRAS CLAVEIncompetencia labial; Electromiografía; Análisis cefalométrico; Músculo orbicular superior de los labios; Músculo orbicular inferior de los labios; Músculo temporal anterior.

“…This is a simplified model which only accounts for the presence of soft and bony tissues without subdividing the former into its main components (fibers, fat, glands, mucosa and three layers of skin). Although the homogeneous tissue assumption has been used in other studies in the past where orthognatic surgery was simulated [19,29] and it is the underlying assumption of preoperative planning commercial softwares such as Materialize Proplan [8,30], a more anatomically accurate representation of the underlying tissues [31][32][33][34][35] would provide a better representation of the elastic response of the lower third soft tissue. Current work in our group is aiming at combining different imaging modalities to overcome the current simplification and provide a more detailed representation of the patient-specific face anatomy [36].…”

Purpose Sliding genioplasty is used to surgically correct a retruded or misaligned chin: in this procedure, an osteotomy is performed and the bony segment is repositioned. In this study we investigate the effect of surgical parameters (bony segment movement, osteotomy design) on postop soft tissue changes in a patient cohort. Methods Seven patients were retrospectively recruited. Cone beam computed tomography data were obtained and soft tissue and bone shape reconstructions were performed. 3D models were created and surgical cuts were replicated according to postop scans. Each model was imported in ANSYS 2019R1 (Ansys Inc, USA) for simulation: the effect of variation in osteotomy plane as well as extent of bony segment movement were assessed by means of design of experiment: surgical parameters were varied in a surgically acceptable range and the soft tissue predictions were evaluated as displacement output of five craniometric landmarks. Results Simulation results show the overall changes of the lower third of the face are sensitive to changes in horizontal and vertical displacement of the bony segment as well as segment rotation. No significant changes in the soft tissue response were to attribute to the osteotomy design. Conclusions Our results are consistent with experimental findings reported in the literature: when planning genioplasty in orthognathic surgery, particular focus on the segment movement (horizontal translation, vertical translation and rotation), rather than on the design of the osteotomy itself, should be considered.
