[Analysis of death cases in the oral emergency department].

In order to analyze the clinical characteristics of death cases in the oral emergency department of the stomatological hospital, and to improve the first aid technique before and in hospitals, we collected the clinical data of death cases in the Department of Oral Emergency in Peking University School and Hospital of Stomatology from January 2010 to January 2023 for retrospective analysis. General cha-racteristics, such as the patients' gender, age, chief complaint, maxillofacial diseases, systemic underlying diseases, rescue situation, cause of death and seasonal distribution of death were summarized. The results showed that a total of 8 death cases (5 males and 3 females) occurred during the 13-year period, ranging in age from 40 to 86 years, with a median age of 66 years. Among the 8 patients, 5 reported bleeding from oral cancer, 1 reported chest tightness and dyspnea after oral cancer surgery, 1 reported loss of consciousness after maxillofacial trauma, and 1 reported oral erosion and aphagia. All the 8 patients had one or more underlying diseases, such as hypertension, coronary heart disease, diabetes, renal failure, and cerebral infarction, etc. and 2 of them showed dyscrasia. Among them, the cause of death in 5 cases was respiratory and circulatory failure caused by oral cancer rupture and hemorrhage or poor surgical wound healing and hemorrhage; 1 case was uremia and hyperkalemia leading to circulatory failure; 1 case was asphyxia caused by swelling of oral floor tissue after maxillofacial trauma; and the other case was acute myocardial infarction caused circulatory failure after oral cancer surgery. According to the vital state at the time of treatment, 6 patients had loss of consciousness, respiratory and cardiac arrest before hospital, and 2 patients suffered from loss of consciousness, respiratory and cardiac arrest during treatment. All the patients received cardiopulmonary resuscitation and some advanced life support measures, and the average rescue time was 46 min. Due to the low incidence of death in the oral emergency department, medical personel have little experience in first aid. First aid training and drills and assessment should be organized regularly. First aid facilities should be always available and regularly maintained by special personnel, such as electrocardiogram (ECG) monitor, defibrillator, simple breathing apparatus, oxygen supply system, negative pressure suction system, endotracheal intubation and tracheotomy equipment. The death cases mainly occurred in the elderly patients with oral cancer bleeding and systemic underlying diseases. Education of emergency awareness for the elderly patients with oral cancer after surgery should be enhanced. Medical staff should strengthen first aid awareness and skills.

Assessment of quality of life in patients with surgically treated maxillofacial fractures.

Background: The complex nature of maxillofacial injuries can affect the surgical treatment outcomes and general well-being of the patient. To evaluate the efficiency of the surgical treatment, assessment of the quality of life (QOL) of the patients is of vital importance. Due to the absence of an exclusive QOL assessment tool for maxillofacial fractures, we introduce the 'Twenty-point quality of life assessment in facial trauma patients in Indian population'. The aim of this study was to assess and evaluate the QOL following surgical management of maxillofacial trauma patients based on the severity of the injury. Methods: The study consisted of 182 subjects divided into two groups of 91 each (Group A: severe facial injury and Group B: mild to moderate facial injury). The Facial Injury Severity Scale (FISS) was used to determine the severity of facial fractures and injuries. The twenty-point quality of life assessment tool includes Zone 1 (Psychosocial impact) and Zone 2 (Functional and aesthetic impact), with ten domains each to assess QOL. Results: In Zone 1, the mean scores for Group A and Group B were 38.6 and 39.26, respectively. In Zone 2, Group B (44.56) had higher mean scores compared to Group A (32.92) (p< 0.001). Group B (83.8) had higher mean scores compared to Group A (71.58) when the total of both Zone 1 and Zone 2 were taken into consideration (p<0,001). In Group A, 9 out of 91 patients had a total score of 81- 100 compared to 68 in the same range in Group B. Conclusions: Proper surgical management with adequate care to the hard and soft tissues can improve the QOL by reducing postoperative psychosocial and functional complications. Aesthetic outcomes play an important role in determining the QOL. Mild/ Moderate injuries show better QOL compared to severe maxillofacial injuries.

Lesiones Oro-maxilofaciales en el Servicio Médico Legal de Curicó, Chile: Estudio descriptivo / Oro-maxillofacial injuries in the Medical Legal Service of Curicó, Chile: Descriptive study

RESUMEN: Las ocurrencias de lesiones en la región oro-maxilofacial adquieren importancia debido a su complicada anatomía y fisiología, pudiendo resultar en deformidades faciales, adquiriendo interés cuando son causadas por un tercero, pudiendo traer repercusiones legales. El objetivo fue realizar un estudio transversal con el fin de estimar frecuencia y tipificación de lesiones oro-maxilofaciales que requirieron peritaje forense en el Servicio Médico Legal de Curicó, Chile. Se recopilaron datos encriptados de 79 fichas de pacientes entre 17-88 años que realizaron su constatación de lesiones en Servicio Médico Legal de Curicó, Chile, en el lapsus de un año. La frecuencia de lesiones con peritaje forense en la región oro-maxilofacial fue de un 25,82 %, provocada principalmente por mecanismo físico. En su mayoría efectuados a individuos del sexo masculino, con un rango etario de entre 20 a 40 años. La violencia interpersonal fue observada como el agente causal más frecuente de lesiones, seguida por accidentes de tránsito. Los sujetos periciados por violencia intrafamiliar, fueron en su totalidad mujeres. Las lesiones más recurrentes fueron fractura y contusión, dentro de ellas encontramos a fractura nasal como la más frecuente, seguida de herida contusa, herida por instrumento cortante, fractura maxilar y por último fractura dental. De la totalidad de las lesiones en estudio solo un tercio estuvieron confinadas exclusivamente en el territorio oro-maxilofacial.

ABSTRACT: Occurrences of lesions in the oromaxillofacial region acquire importance due to their complicated anatomy and physiology, which may result in facial deformities, acquiring interest when caused by a third party, and may have legal repercussions. The objective was to carry out a crosssectional study in order to estimate the frequency and typing of oro-maxillofacial injuries that required forensic expertise in the Legal Medical Service of Curicó, Chile. Encrypted data was collected from 79 records of patients between 17-88 years who made their findings of injuries in the Medical Legal Service of Curicó, Chile, in the lapse of one year. The frequency of injuries with forensic expertise in the oro-maxillofacial region was 25.82 %, caused mainly by physical mechanism. Mostly made to individuals of the male sex, with an age range of between 20 to 40 years. Interpersonal violence was observed as the most frequent causal agent of injuries, followed by traffic accidents. The subjects trained by intrafamily violence were all women. The most recurrent injuries were fracture and contusion, within which we found a nasal fracture as the most frequent, followed by a contusive wound, a cutting instrument wound, a maxillary fracture and finally a dental fracture. Of the totality of the lesions under study, only one third were confined exclusively in the oro-maxillofacial territory.

Introduction: The maxillofacial region is vulnerable to injuries. In Cuba, few studies related to urgent care services have been carried out in maxillofacial traumatology, which led to an increase of motivation to conduct this research. Objective: To characterize maxillofacial trauma from a clinical and epidemiological point of view in patients treated in General Calixto García Hospital from June 2016 to June 2017. Material and Methods: A descriptive cross-sectional study was conducted with the universe of patients (2412 ones) that were treated in the Emergency Service of General Calixto García University Hospital with the diagnosis of maxillofacial trauma from June 2016 to June 2017. The variables used were: age groups, sex, etiological factor, type of injury, and therapeutic behavior. Results: In the study, the patients aged between 19 and 30 years represented 41.0 percent; the male sex 69.0 percent; and the traffic accidents 34.6 percent. The most frequent hard tissue injuries were nasal fractures (13.9 percent); and the soft tissue injuries were purely integumentary wounds (82.1 percent). Bandage placement was used in 89.1 percent, and wound suture in 84.1 percent. Conclusions: The behavior of the maxillofacial trauma in the Emergency Service of General Calixto García University Hospital, showed that it predominates in men of middle age due to traffic accidents. Soft tissue injuries were the predominant type of injuries, among them, the purely integumentary wounds. The conservative behavior in its modality of bandage placement was the most commonly used(AU)

Changing pattern and etiology of maxillofacial fractures during the civil uprising in Western Libya

Background: The purpose of the present study was to evaluate changing pattern in characteristics of maxillofacial fractures and concomitant injuries in Western Libya During revolution and to assess the association between mechanism of injury and fracture patterns. Material and Methods: A retrospective review of medical records and radiographs of 187 patients treated for maxillofacial fractures from January 2010 to December 2012 was performed, there were 326 fractures in 187 patients. Results: The male: female ratio was 6:1. Most fractures occurred in patients aged 11 to 40 years, and few injuries occurred in patients aged > 50 years. Most fractures occurred from motor vehicle accidents, and other most frequent causes included assault, gunshot, and fall injuries. Most maxillofacial fractures involved the mandible, zygomatic complex, or maxilla. Most mandibular fractures occurred at the parasymphysis, angle, or condyle. Associated injuries most frequently involved the head, chest, and extremities. Most patients were treated with open reduction (132 patients [71%]), and 26 patients (14%) were treated nonoperatively. There were 21 complications (11%). Conclusions: In summary, motor vehicle accidents were the most frequent cause of maxillofacial fracture in western Libya, possibly because of the lack of seat belt legislation. Interpersonal violence was a less frequent cause of maxillofacial fracture, possibly because of the religious restriction on alcohol consumption (AU)

Introduction: midface fractures are a serious medical problem due to their complexity, frequency and socioeconomic impact. Objective: conduct a literature review about the anatomical considerations, diagnosis, classification, treatment and complications of midface fractures. Methods: A literature review was conducted in September 2016. The evaluation included high impact journals from the Web of Science (25 journals) and 2 books. The databases MEDLINE, PubMed and SciELO were consulted, using the descriptors maxillary fracture, treatment, lefort fracture. Papers written in English in the last five years were included. Of the 98 papers obtained, the study considered 40. Data analysis and integration: the middle third of the face is characterized by anatomical weakness, since it is formed by scantily protected spongy bone with multiple sutures. There are many classifications for midface fractures, and diagnosis is based on clinical findings, particularly ophthalmological, which alongside those of auxiliary diagnostic devices, make it possible to choose the most appropriate therapeutic mode and prevent complications. Conclusions: the anatomical characteristics of the facial middle third justify the frequency and impact of these fractures. Diagnosis should be based on interrogation, physical examination and the use of auxiliary diagnostic imaging, mainly tomography. Upon classification of the fracture, a treatment plan may be devised based on individual assessment of each case to prevent future complications(AU)

Prosthetic, orthodontic and implant-supported rehabilitation of five maxillary anterior teeth with alveolar bone loss

ABSTRACT Introduction: Treatment of maxillofacial injuries is complex and requires the establishment of a comprehensive and accurate diagnosis and correct treatment planning. Objective: The objective of this case report was to describe the re-treatment of a 27-year-old woman who was involved in a severe car accident that resulted in the loss of five anterior teeth and alveolar bone, and whose previous orthodontic and surgical treatments had been unsuccessful. Case report: In this case, the space for the missing mandibular molar was reopened to allow for rehabilitation. The positions of the mandibular incisors were improved. The right mandibular canine was moved to the mesial, allowing for correction of the Class II canine relationship on that side, and implants were placed to replace the maxillary anterior teeth. Conclusion: Anterior aesthetic and functional rehabilitation using a multidisciplinary approach was essential to improve the patient's facial aesthetics, to obtain great improvement in function and to achieve occlusal stability after 2 years of follow-up.

RESUMO Introdução: o tratamento de danos bucomaxilofaciais é complexo e requer diagnóstico abrangente e preciso, além de um correto plano de tratamento. Objetivo: o objetivo deste relato de caso foi descrever o retratamento de uma paciente do sexo feminino, 27 anos de idade, envolvida em acidente automobilístico grave, que resultou na perda de cinco dentes, além de perda óssea alveolar na região anterior. Relato de caso: a paciente apresentava histórico de insucesso de tratamento ortodôntico e cirúrgico. No caso apresentado, o espaço referente aos molares inferiores ausentes foi reaberto, para possibilitar a reabilitação. Houve melhora no posicionamento dos incisivos inferiores. O canino inferior direito foi deslocado para mesial, possibilitando a correção da relação de Classe II intercaninos do mesmo lado. Implantes foram inseridos a fim de substituir os dentes superiores da região anterior. Conclusão: a reabilitação estética e funcional da região anterior, realizada por meio de uma abordagem multidisciplinar, foi fundamental para valorizar a estética facial da paciente, melhorar a função e promover estabilidade oclusal após dois anos de acompanhamento.

Atención inicial al politraumatizado maxilofacial: evaluación, conducta terapéutica y prevención / Initial care of maxillofacial polytrauma patients: evaluation, therapeutic management and prevention

Introducción: las fracturas maxilofaciales requieren tratamiento de urgencia y de un personal altamente calificado. Pueden aparecer complicaciones que ocasionen la pérdida de la vida del paciente. Objetivo: realizar una revisión bibliográfica sobre la atención al politraumatizado maxilofacial, enfatizando aspectos del soporte vital avanzado de trauma como el manejo del déficit neurológico, de la exposición del paciente y del control de la temperatura, anexos a la valoración primaria, valoración secundaria, tratamiento definitivo, lesiones asociadas, equipo multidisciplinario del trauma, traumatismos maxilofaciales con características distintivas, condiciones que influyen en el manejo del trauma y prevención. Métodos: se realizó una revisión bibliográfica entre diciembre de 2014 y enero de 2015. Se evaluaron revistas de impacto de Web of Sciencies (39), 1 cubana y 5 libros. Se consultaron las bases de datos de los sistemas MEDLINE, PubMed y SciELO. Se utilizaron como descriptores: maxilofacial trauma, advanced trauma life support, secondary survey, associated injuries, multidisciplinary team of trauma, prevention y sus equivalentes en español. Se incluyeron artículos en inglés y español, publicados preferentemente en los últimos 5 años. Se obtuvieron 141 artículos. El estudio estuvo circunscrito solo a 51, que enfocaban estas temáticas de forma más integral. Análisis e integración de la información: al analizar el comportamiento de los artículos atendiendo a su representatividad en las revistas científicas, encontramos que 5,9 por ciento correspondían a la Journal of Craniomaxillofacial Surgery. Conclusiones: es imprescindible que los cirujanos maxilofaciales que se desempeñan en la atención de emergencia puedan reconocer, diagnosticar y establecer el manejo básico de un traumatismo maxilofacial. La falta de diagnóstico y de correcto manejo puede conducir a la pérdida de funciones y al desarrollo de deformidades secundarias difíciles de corregir luego. Esta corrección también podría inducir resultados decepcionantes, que podrían comprometer la vida del paciente(AU)

Introduction: maxillofacial fractures require emergency treatment by highly qualified personnel. Complications may occur which may cause the death of the patient. Objective: carry out a bibliographic review about the care of maxillofacial polytrauma patients, highlighting the following aspects of advanced trauma life support: management of neurological deficit, exposure and temperature control, annexes to primary assessment, secondary assessment, definitive treatment, associated injuries, multidisciplinary trauma team, maxillofacial traumas with distinctive characteristics, conditions influencing trauma management and prevention. Methods: a bibliographic review was conducted from December 2014 to January 2015. The evaluation included high impact journals from the Web of Sciences (39 journals), as well as one Cuban journal and five books. The databases MEDLINE, PubMed and SciELO were consulted, using the search terms maxillofacial trauma, advanced trauma life support, secondary survey, associated injuries, multidisciplinary trauma team, prevention, and their Spanish counterparts. The review included papers in English and Spanish, preferably published the last five years. Of the 141 papers obtained, the reviewers selected the 51 which approached the study topics in a more comprehensive manner. Data analysis and integration: analysis of the representativeness of papers in scientific journals revealed that 5.9 percent corresponded to the Journal of Craniomaxillofacial Surgery. Conclusions: it is indispensable for emergency maxillofacial surgeons to be able to recognize, diagnose and determine the basic management of maxillofacial trauma. Lack of a diagnosis or inappropriate management may lead to the loss of functions and the development of secondary deformities difficult to correct in the future. Such correction could also lead to disappointing results which may risk the patient's life(AU)

Hemorragia incoercible por trauma maxilofacial: experiencia del Hospital del Trabajador / Management of intractable bleeding facial trauma

Introduction: The aim of this paper is to show our experience in the management of intractable bleeding facial trauma during the past 10 years to determine its impact on our environment and outline the basic principles of treatment. Methods: A retrospective study of all patients with maxillofacial trauma and uncontrollable bleeding from 1999 to 2009. Inclusion criteria were oro-nasal bleeding secondary to maxi-llofacial trauma requiring emergency treatment by a specialist, without other associated lesions that could be a source of bleeding. We obtained demographic information, mechanism of injury, diagnosis of injury, hemodynamic status, type and timing of tamponade, definitive surgical treatment, results and evolution. Results: 21 patients in the study period, a true incidence of 0.002 percent. 7 patients (33.3 percent) with trauma naso-septal; 5 (23.8 percent) with panfacial fractures, and 7 (33.3 percent) with variable involvement of the upper and middle face. Nine patients (42.9 percent) had isolated facial injuries. Only 5 patients (23.8 percent) had hemodynamic compromise. Thirteen patients (61.9 percent) required posterior nasal packing with or without another procedure to control bleeding. Eight patients (38.1 percent) required early reduction and internal fixation as definitive treatment. Conclusions: Maxillofacial trauma uncontrollable bleeding is uncommon and rarely is the primary cause of hypovolemic shock. It should be suspected in patients with facial injuries from hours bleeding. The packing, suturing of wounds and reduce/OTS are the mainstays of early treatment.

Introducción: El objetivo del presente trabajo es mostrar nuestra experiencia en el manejo de la hemorragia incoercible por trauma facial durante los últimos 10 años, para determinar su incidencia y delinear los principios básicos del tratamiento. Material y Método: Estudio retrospectivo de todos los pacientes con hemorragia incoercible por trauma maxilofacial entre 1999 y 2009. Criterios de inclusión fueron hemorragia oro-nasal secundaria a traumatismo maxilofacial, sin otras lesiones asociadas que pudieran ser fuente de hemorragia, que requirió de tratamiento de urgencia por un especialista. Se obtuvo información demográfica, mecanismo de injuria, diagnóstico del traumatismo, estado hemodinámico, tipo y momento del tratamiento especializado, tratamiento quirúrgico definitivo, resultados y evolución. Resultados: 21 pacientes en el período de estudio, con incidencia real de 0,002 por ciento. Destacan 7 pacientes (33,3 por ciento) con trauma nasoseptal, con o sin heridas faciales; 5 (23,8 por ciento) con fracturas panfaciales; 7 (33,3 por ciento) con compromiso variable del tercio superior y medio de la cara. Nueve pacientes (42,9 por ciento) presentaron lesiones faciales aisladas. 5 pacientes (23,8 por ciento) presentaron compromiso hemodinámico. Trece pacientes (61,9 por ciento) necesitaron un taponamiento nasal posterior, asociado o no a otro procedimiento para el control de la hemorragia. Ocho pacientes (38,1 por ciento) necesitaron reducción y osteosíntesis precoz como tratamiento definitivo. Conclusiones: La hemorragia incoercible por trauma maxilofacial es poco frecuente y rara vez es la causa primaria de shock hipovolémi-co. Se la debe sospechar especialmente en pacientes con lesiones faciales que llevan horas con sangrado, aún de poca cuantía, pero persistente. El taponamiento, sutura de heridas y reducción/OTS precoz son los pilares de su tratamiento.

Dentoalveolar trauma was present in 7.5% ofpatients.Conclusion: The incidence of facial fractures in Brazilian population is similar thanpreviously reported elsewhere. There were most common in male patients, mainly due totraffic accidents/motorcycle and physical violence(AU)

Simultaneous occurence of compound odontoma and arrested root formationas developmental disturbances after maxillofacial trauma: A case report

Traumatic injury to a primary tooth and/or a bone fracture has the potential to damage the underlying permanenttooth germ which may disturb its development. The extent of the malformation depends on the developmentalstage of the permanent tooth and the intensity of the trauma. The presence of infection may be a predictive factorfor these abnormalities. Open surgical procedures can also potentially cause impaction and developmental disturbances.Several developmental alterations such as discolouration, hypoplasia, crown dilaceration, root angulationor dilaceration, sequestration of permanent tooth buds and disturbance in eruption have been reported in permanentteeth after trauma. However, odontoma-like malformations and partial or complete arrest of root formationare rare complications developed after trauma. This article presents a rare case with simultaneous occurrence ofan odontoma-like malformation and complete and partial arrested root formations as the results of maxillofacialtrauma. Almost all pediatric fractures must be managed with closed reduction as much as possible. However, if itis necessary to perform an open reduction, careful attention must be paid during placement of the osteosyntheticplates and screws; and tooth bud development must be followed periodically (AU)

Acúmulo de sementes de Acrocomia aculeata (Arecaceae) na bochecha de búfalos no Pará / Acumulation of the seeds of Acrocomia aculeata (Arecaceae) in the cheeks of buffaloes in the State of Pará, Brazil

Foi demonstrado que uma condição em búfalos caracterizada pelo aumento de uma das bochechas é causada pelo acúmulo das sementes da palmeira "mucajá"(Acrocomia aculeata, fam. Arecaceae) e de capim no vestíbulo oral, durante a ruminação. Esse acúmulo de sementes causou atrofia por compressão com adelgaçamento e desvio medial do osso mandibular correspondente e exposição das raízes dos dentes molares. Aparentemente os frutos dessa palmeira possuem boa palatabilidade para búfalos.

A condition of buffaloes characterized by an increased volume of one of the cheeks was shown to be due to accumulation of the seeds of the palm-tree "mucaja" (Acrocomia aculeata) and of grass, in the oral vestibulum during rumination. This caused compressive atrophy with thinning and medial deviation of the corresponding submaxillary bone and exposition of the roots of molar teeth. The seeds appear to be of good palatability to the buffaloes.

Titanium mesh has importantadvantage for your manipulation and installation with easy adaptation in the selected place. Our objective was present a cases series with zygomatic complex fracture and with naso-orbito-ethmoidal fracture, when titanium mesh showing efficiency for the management of orbital reconstruction.

Epidemiología del trauma severo con implicación maxilofacial / Epidemiology of the severe trauma with maxillofacial implication

Se realizó un estudio prospectivo y trasversal en 546 pacientes víctimas de politraumas severos que fueron atendidos en el Departamento de Emergencia del Hospital Provincial Docente Saturnino Lora de Santiago de Cuba durante el año 2002. De estos pacientes, 114 presentaron lesiones maxilofaciales, de los cuales 19 fallecieron, tanto en la escena del accidente, en tránsito hacia el hospital, como en la propia institución; 95 pacientes con lesiones maxilofaciales sobrevivieron. Se corroboró que la severidad de estas lesiones no guarda relación con la severidad integral de las lesiones sostenidas según los resultados del AIS e ISS, respectivamente. La causa de este tipo de lesiones es multifactorial, con predominio de los accidentes automovilísticos y de motores. Las fracturas de mandíbula, cigomáticas y nasoetmoidales resultaron los patrones de lesiones esqueléticas de mayor incidencia. Los procedimientos ortopédicos y quirúrgicos predominaron según ese orden. Se constataron 245 lesiones asociadas y 29 omitidas en estos pacientes durante el examen inicial. Nuestros hallazgos enfatizan la necesidad de la participación activa y precoz de los cirujanos maxilofaciales con experiencia en la atención de estos pacientes, en estrecha asociación de trabajo con cirujanos generales, neurocirujanos y ortopédicos, para la atención integral y óptima de estos lesionados(AU)

Fracturas maxilofaciales en individuos chilenos / Maxillofacial fractures in chilean subjects

Las fracturas orales y maxilofaciales representan un 6 por ciento a 8 por ciento de las fracturas óseas corporales. Estas lesiones son de complejo manejo y exigen un diagnóstico precoz, certero y preciso. El Hospital Regional Hernán Henríquez Aravena, de la ciudad de Temuco, no posee cirujanos orales y maxilofaciales en los equipos de urgencia inmediata, de forma que los ingresos son realizados por otros profesionales. En un año de seguimiento se realizaron 34.931 consultas medico-legales en el Servicio de Urgencia del Hospital Regional Hernán Henríquez Aravena. De esas consultas se escogió una muestra representativa de 742 sujetos de quienes se obtuvo información general y de las lesiones en particular. Se obtuvo también asociación estadística mediante la prueba Chi Cuadrado. Seis por ciento de las consultas en el Hospital Regional Hernán Henríquez Aravena fueron asociadas a fracturas maxilofaciales, donde el grupo con más consultas fueron el de los menores de 20 años. Del total muestral, el 64.4 por ciento correspondió a sujetos del sexo masculino, manteniendo una relación hombre:mujer de 3.1:1; sin embargo, esta relación aumento su diferencia en sujetos mayores de 15 años. El 31.1 por ciento de las consultas fueron causadas por agresiones, mientras que 24.4 por ciento fueron asociadas a las caídas. La principal zona de fractura fue el complejo orbito-naso-etmoidal con un 55.6 por ciento y las fracturas dentoalveolares con un 22.2 por ciento. Existió asociación estadísticamente significativa entre edad, sexo, agresión, fracturas mandibulares y fracturas dentoalveolares (p < 0.05). Los datos reflejan la alta prevalencia de fracturas maxilofaciales en la comuna de Temuco, Chile, siendo similar a lo que ocurre en otras partes del mundo. El grupo de los jóvenes es el de principal consulta donde las agresiones juegan un papel fundamental. Con el presente estudio descriptivo creemos que se justifica plenamente la presencia de cirujanos orales y maxilofaciales en...

The oral and maxillofacial trauma represent a 6% to 8% approximately of the body fractures. These injuries are of complex handling and demand an accurate and precise diagnosis. The Hernán Henríquez Aravena Regional Hospital, of Temuco city, does not have oral and maxillofacial surgeons in the immediate urgency staff, so that first approach to handle those patients is made by other clinicians. After one year, a total of 34,931 consultations were made in the Urgency Service at the Hernán Henríquez Aravena Hospital. Of them, a representative sample of 742 subjects was chosen from which general information and the kind of injuries was obtained. Statistical association with the Chi - Square test was obtained. Six percent of the consultations in the Hernán Henríquez Aravena Regional Hospital were associated to maxillofacial fractures. 64.4% of the sample corresponded to male subjects. The relation man to woman was 3.1:1, displaying a greater difference in patients aged over 15 years. Of the total of sample, the group with more consultations was those aged below 20 years and the 31,1% of the consultations were caused by aggressions, whereas 24,4% were associated to falls. The main zone of fracture was related to the orbit nose etmoidal complex with 55,6% and dental fractures with a 22.2%. Statistically significance association was found between age, sex, aggression, mandible and dental fractures (p < 0,05) The data reflect the high prevalence of maxillofacial fractures in Temuco, Chile, similar to other parts of the world. The group of young people is the one of main consultation where the aggressions play a fundamental roll. With the present descriptive study we think that the presence of oral and maxillofacial surgeons in the urgency staff of the Hernán Henríquez Aravena Regional Hospital, Temuco, Chile is justified totally.

Atención de Urgencia en Traumatismos de Cara / Urgency Attention in Face Traumatisms

La cara es la región del organismo más expuesta a las heridas. En el paciente traumatizado con heridas en la cara, se deben atender en primera instancia los aspectos que puedan conducirlo a la muerte. Se debe hacer una rápida inspección del paciente, controlar su respiración, la hemorragia y el posible choque y evaluar las lesiones acompañantes para diagnosticar y tratar las lesiones maxilofaciales posteriormente. Los signos y síntomas que con más frecuencia se presentan en estos pacientes son rinorrea, inconsciencia, heridas oculares y lesiones del tórax. El paciente con trauma en cara puede presentar desde abrasiones y avulsiones cutáneas, heridas de cuero cabelludo, nervio facial, parótida y del conducto de Stenon, lengua, labios, párpados, orejas y nariz, hasta heridas por arma de fuego y tatuajes. Por esto, es importante prevenir al cirujano general contra el riesgo de efectuar ciertos procedimientos quirúrgicos, que por su complicación, requieren de la intervención de un especialista
