Complications in Orthognathic Surgery.

The aim of this study was to analyze the presence of complications related to orthognathic surgery performed by surgeons in train. A retrospective study was conducted between 2005 and 2014, analyzing the clinical records of patients treated in the authors' Department. Patients who underwent orthognathic surgery were included, under a bidimensional analysis and with the conventional orthosurgical sequence; intraoperative complications were identified, such as the occurrence of a bad split, bleeding, tissue injury, among others and postoperative variables such as impaired sensation, infection, and alterations in the osteosynthesis systems. A statistical analysis was done using χ and Student t tests, considering a statistical significance when P < 0.05. Two hundred fifty patients were included with an average follow-up of 13 months; 62.8% were women and 37.2% were men; 18.8% of the subjects presented some type of intraoperative or postoperative complication; excluding relapse and complications due to loss of bonding of the orthodontic device, a 12.4% complication rate was observed; intraoperative complications were 8% and postoperative complications 10.4%. Only the sensorineural alterations were associated with the mandibular surgery (P < 0.05). Finally, orthognathic surgery is relatively safe and produces a low number of complications when it is performed by surgeons in train.

In Vitro Mechanical Analysis of Different Techniques of Internal Fixation of Combined Mandibular Angle and Body Fractures.

PURPOSE: To evaluate in vitro resistance of 5 techniques of internal fixation of bilateral fractures involving the mandibular angle and body. MATERIALS AND METHODS: Twenty-five polyurethane mandibles were used as substrates, fixed with a 2-mm fixation system, and divided into 5 groups: I, 1 4-hole plate, without intermediate space, in the neutral zone of the mandibular body and another similar plate in the external oblique ridge of the contralateral mandibular angle; II, 1 6-hole plate, with intermediate space, in the neutral zone of the mandibular body and a similar plate in the external oblique ridge of the left mandibular angle; III, 1 4-hole locking plate, with intermediate space, in the right neutral zone and another similar plate in the left external oblique ridge; IV, 2 4-hole plates, with intermediate space, one in the tension zone and the other in the compression zone of the mandibular body, and 1 4-hole plate, with intermediate space, in the external oblique ridge of the contralateral mandibular angle; V, 2 4-hole plates with intermediate space, one in the tension zone and the other in the compression zone of the mandibular body and similarly in the buccal side of the left mandibular angle. Mandibles were subjected to vertical linear load tests by a mechanical testing machine (Instron 4411, Instron Corp, Norwood, MA) to record peak load and load for displacements of 3, 5, and 7 mm. RESULTS: Group I had the least mechanical resistance of all groups, regardless of displacement, and group IV had the greatest mechanical resistance. Among groups II, III, and V, there was no statistically meaningful difference. CONCLUSION: Fixation of bilateral mandibular fractures involving the mandibular angle and body using 2 plates in the region of the body and 1 plate in the tension zone in the region of the mandibular angle was the technique that presented the best mechanical resistance.

Creencias y prácticas en salud oral en comunidades indígenas para el diseño de un modelo de atención integral de salud con enfoque intercultural en Colombia. Una revisión / Cosmovision of oral health in indigenous communities for the design of a comprehensive health care model with intercultural approach in Colombia. A review

Objetivo: identifcar, con base en la literatura disponible, la cosmovisión de la salud oral para los pueblos indígenas. Métodos: se realizó una revisión sistemática de la literatura a través de diferentes bases de datos. Resultados: las creencias y prácticas de las comunidades indígenas responden a la cosmovisión del proceso de salud-enfermedad oral, las cuales dan cuenta de una perspectiva mítica, espiritual y en muchas ocasiones se aborda desde un punto de vista naturalista. Conclusión: las creencias y prácticas de la salud oral para las comunidades indígenas han trascendido, en gran medida, la perspectiva mágica y se ubican actualmente en una óptica tanto técnica como medicinal.

Objective: To identify, based on the available literature, the worldview of oral health for indigenous peoples. Methods: A literature search was carried out through diferent databases. Results: The cosmovision of the oral health-disease process revolves around a mythical, spiritual perspective and in many occasions, it is approached from a naturalistic perspective. Conclusion: The worldview of oral health-disease for indigenous communities has largely transcended the magical perspective and is currently located in a technical as well as a medicinal perspective.

Linfoma no hodgkin de células de manto: relato de caso raro y la presentación a los profesionales de la salud de la importancia de un diagnóstico precoz / Lymphoma, mantle cell lymphoma: case report and presentation weird to health professionals of the importance of early diagnosis

Después del carcinoma epidermoide, los linfomas representan el segundo grupo de neoplasias que comprometen la región de la cabeza y cuello, la exploración de este tema es importante en función de la elevada incidencia en los últimos años especialmente los linfomas no Hodgkin. Este linfoma se puede presentar en la región de cabeza y cuello de diversas formas, con compromiso ganglionar y/o extraganglionar, el sitio más común en la región de cabeza y cuello, es el anillo de Waldeyer, seguido por la órbita y anexos, senos paranasales, glándulas salivales, cavidad bucal, laringe y tiroides. En el siguiente trabajo vamos a presentar un caso clínico y en el abordar la necesidad de el conocimiento de el odontólogo-cirujano y demás profesionales de la salud sobre la lesión, con el fin de posibilitar un diagnostico precoz, contribuyendo para un mejor pronostico, prolongar tiempo de vida y mejorar la calidad de vida para este paciente

After the squamous cell carcinoma, lymphomas represent the second group of neoplasms of the head and neck region. Explore this issue proved to be important because the increase of incidence in recent years, especially non-Hodgkin lymphomas. This lymphoma can occur in the head and neck in different ways, with nodal involvement and / or extranodal. When the extranodal site most common in head and neck is the ring of Waldeyer, followed by orbit and attachments, paranasal sinuses, salivary glands, oral cavity, larynx and thyroid. This study sought to present a case report and address the need for knowledge of the dentists and other health professionals about the injury, so that they can make the diagnosis earlier and thus could contribute to a better prognosis, longer survival and better quality of life for this patient
