| The number of doctoral programs in the biomedical field has risen in recent decades, but with a concentration in Santiago and little expansion into the provinces. The aim of this article is to describe the initial results obtained by the Doctorate in Medical Sciences program of the Universidad de La Frontera, Chile. Observational study, conducted in the Department of Surgery at the Universidad de La Frontera, Chile. All cohorts in the program from 2008 to 2015 were included. The outcome variables were: Graduation rate and scientific productivity of the graduates (WoS and SciELO publications). Other variables of interest were: academic faculty productivity (WoS and SciELO publications), and characteristics of students who entered the program (age, sex,... |

| The maxillary sinus (MS) is described as a pyramid-shaped cavity of the maxilla. Knowledge of its morphology makes it possible to define normality and abnormality so that its three-dimensional analysis can be a valuable preoperative tool during surgery in this anatomical area. The aim of this study is to present a strategy of morphological analysis of the MS using 3D printing acquired through computed cone beam tomography (CBCT) images. A cross-sectional descriptive study was conducted, including 15 subjects (8 women and 7 men). The 3D virtual reconstruction and modeling was done on the MSs bilaterally, and 30 physical models were produced on a 3D printer. The results revealed that the MSs obtained exhibited various morphologies. An individual analysis of... |

| Class II and class III skeletal anomalies require treatments that are both esthetic and functional, so the purpose of this investigation was to study the relationship between facial soft and hard tissues of patients with class II and class III deformities in the lower third of the face. A descriptive study was designed which included class II subjects with a SNB angle less than 78 and class III with a SNA angle less than 80. The soft tissue width was analyzed in relation to the Pg point, A point, B point, and upper and lower incisor cervical points. The naso-labial angle and interincisal angle were also analyzed. The studies were done using cone beam computerized tomography and analyzed with the software Simplant O&O (Materialise, Belgium). The results... |

| The aim of this research was to evaluate the risk factors related to condylar resorption (CR) after orthognathic surgery. Was realized a systematic review with a search of the literature performed in the electronic databases PubMed, MedLine, Ovid, Cochrane Library for current evidence in the world literature as conducted, and relevant articles were selected in according to inclusion and exclusion criteria and the findings were compared. Eight papers, (follow-up 12 months to 69 months) were including. A sample of 2567 patient with mandible or bi maxillary surgery with an age range from 14 to 46 year old was observed. In 137 patients (5.3%) CR was observed , with a 97.6% (122) female. CR was related to 118 cases with mandibular deficiencies with high... |

| La mayoría de los diagnósticos de procesos estiloides elongados y osificaciones de ligamentos estilohioideos corresponden a hallazgos en el análisis de radiografías panorámicas. En la presente investigación se evaluaron 3028 Radiografías Panorámicas digitales, tomadas entre Junio de 2009 y Junio de 2011. Se registraron las osificaciones de ligamento estilohiodeo de acuerdo a sexo, edad y bilateralidad. El análisis de datos se desarrolló con el Test estadistico Chi cuadrado, con un nivel de significancia estadística a< 0,05. En las imágenes evaluadas se encontró una prevalencia de osificaciones de un 8,42%, siendo más frecuentes en individuos de sexo femenino, osificaciones bilaterales y con patrón discontinuo. En cuanto a la edad se evaluó de acuerdo a... |

| La asimetría facial es una patología de compromiso funcional y estético que puede estar generado por hiperplasia condilar; el objetivo de esta investigación es determinar la influencia del tamaño condilar en la asimetría facial. Doce sujetos fueron estudiados mediante el análisis de tomografía computadorizada cone beam; todos los pacientes presentaron cintigrama óseo que determino la presencia de hiperplasia condilar activa; el análisis se realizo en un software del sistema de captura modelo Pax Zenith, marca Vatech (Korea 2011), utilizando 90 kV y 120 mA; se obtuvo mediciones de la distancia antero-posterior, superior-inferior y medio-lateral de la cabeza del cóndilo, relacionándose con la posición del cóndilo con la línea mediana facial y la posición de... |

| Los osteomas fronto-etmoidales son los tumores benignos más frecuentes de los senos paranasales, pudiendo evolucionar con complicaciones por compresión de estructuras adyacentes. Se presenta el caso de una paciente de 63 años de edad, que consultó por aumento de volumen nasofrontal, cefalea y diplopía. Tras el examen clínico, se evidenció una asimetría facial con lateralización del bulbo ocular derecho y exoftalmo. La tomografía de los senos paranasales mostró una lesión que ocupa parcialmente el seno frontal, etmoidal y parte de la cavidad nasal. Los cuidados anatómicos y planificación quirúrgica se desarrollaron en un modelo estereolitográfico mientras que la cirugía de exéresis total se realizó con ayuda del sistema piezoeléctrico. El examen histológico... |
