ABSTRACT

As fraturas faciais em crianças são raras, já que os ossos faciais pediátricos têm maior elasticidade, menos pneumatização, tecido adiposo circundante mais espesso e mais estabilização da mandíbula e maxila pelos dentes não irrompidos. Em geral, lesões nos tecidos moles são mais comuns em crianças do que fraturas esqueléticas. Entre as fraturas faciais pediátricas, as fraturas da mandíbula são as mais comuns, sendo o côndilo a área mais acometida em pacientes pediátricos. O côndilo é considerado o principal centro de crescimento da mandíbula em crianças, assim é de suma importância a definição do tratamento adequado, pautado em diversos critérios de avaliação, com o intuito de erradicar possíveis complicações advindas da fratura condilar. Assim o objetivo deste estudo é relatar um caso de fratura de côndilo unilateral em uma criança, na qual realizou-se abordagem cirúrgica com fixação interna, afim de elucidar e discutir as possíveis condutas terapêuticas acerca de tratamentos a serem aplicados, visto que esses ainda são bastante controversos na literatura e os resultados das diversas condutas são os mais diversos, apresentando variados aspectos que interferem na evolução dos pacientes(AU)


Facial fractures in children are rare, since pediatric facial bones have greater elasticity, less pneumatization,thicker surrounding adipose tissue and more stabilization of the jaw and jaw by unerupted teeth.In general, soft tissue injuries are more common in children than skeletal fractures.Among pediatric facial fractures, mandible fractures are the most common, with condyl being the most affected area in pediatric patients.The condyl is considered the main center of mandible growth in children, so it is of Paramount importance to define the appropriate treatment, based on several evaluationcriteria, in order to eradicate possible complications resulting from the condilar fracture.Thus, the aim of this study is to report a case of unilateral condyl fracture in a child, in which a surgical approach with internal fixation was performedin order to elucidate and discuss the possible therapeutic approaches about treatments to be applied, since these are still quite controversial in the literature and the results of the various behaviors are the most diverse,presenting several aspects that interfere in the evolution of patients(AU)

ABSTRACT

Fraturas faciais podem ocorrer de forma isolada ou concomitante a outras lesões. O complexo zigomático orbitário (CZO) ocupa uma posição proeminente da face, deixando-o bastante susceptível a traumas de alto e baixo impacto, que podem causar afundamento facial. O trauma de face frequentemente resulta em danos ao tecido ósseo, tecido mole e elementos dentários, causando prejuízo na função e estética do paciente. Os acidentes automobilísticos são uma das causas mais significativas de traumas faciais. As fraturas do terço médio da face incluem as que afetam a maxila, o zigoma e complexo NOE. O presente estudo tem por objetivo relatar o caso clínico de um paciente de 47 anos, sexo masculino, vítima de acidente automobilístico (carro x carro). Diagnosticado com fratura do CZO direito, classe IV. Foi realizada redução incruenta da fratura de arco zigomático; redução e fixação interna rígida de fratura de parede lateral de órbita e pilar zigomático com instalação de camadas de surgicel na região para melhora do contorno, resultando em regressão do afundamento malar e consequente reestabelecimento estético funcional. Estudos como este podem ser fonte de referência em busca constante pelo aprimoramento profissional, objetivando completo domínio teórico-prático das formas de condutas e tratamentos específicos à situação em questão... (AU)


Facial fractures may occur in isolation or concomitantly with other injuries. The zygomatic orbital complex (ZOC) occupies a prominent position of the face, leaving it quite susceptible to high and low impact trauma, which can cause facial sinking. Face trauma often results in damage to bone tissue, soft tissue and dental elements, causing injury to the patient's function and aesthetics. Auto accidents are one of the most significant causes of facial trauma. Fractures of the middle third of the face include those affecting the maxilla, the zygoma, and the NOE complex. The present study aims to report the clinical case of a 47-year-old male patient, victim of an automobile accident (car x car). Diagnosed with right CZO fracture, class IV. A non-invasive reduction of the zygomatic arch fracture was performed; reduction and rigid internal fixation of lateral wall orbital fracture and zygomatic pillar with installation of surgicel layers in the region to improve the contour, resulting in regression of the malar sinking and consequent functional aesthetic reestablishment. Studies like this can be a source of reference in constant search for professional improvement, aiming at a complete theoretical-practical domain of the forms of conduct and treatments specific to the situation in question...

ABSTRACT

The maxillofacial skeleton is the basis of the contour of the face. Orthognathic surgery and facial contouring surgery change jaw tissue and affect facial appearance in different manners. Orthognathic surgery is the main method to correct dental and maxillofacial deformities. It changes the shape of the jaw and improves the occlusal relationship by changing the three-dimensional position of the jaw. Facial contouring surgery mainly adopts the method of "bone reduction", which changes the "amount"of the jawbone by cutting a part of the bone tissue to improve the facial appearance, generally without changing oral function. The combined use of orthognathic surgery and facial contouring surgery is becoming increasingly common in clinical practice. This also requires oral and maxillofacial surgeons to have a holistic consideration of the comprehensive correction of maxillofacial bone deformity, and to perform comprehensive analysis of jaw deformities and jaw plastic surgery to achieve the most ideal results. The author's team has been engaged in the clinical work of orthognathic surgery and facial contouring surgery and accumulated rich clinical experience in the comprehensive correction of maxillofacial bone deformity. In this article, the indications, treatment goals, treatment modes, treatment methods, and key points in the surgical operations of comprehensive maxillofacial bone surgery were summarized.

ABSTRACT

ABSTRACT Understanding the cause, severity, and elapsed time for the restoration of the functions of maxillofacial injuries can contribute to the establishment of clinical priorities aiming at effective treatment and further prevention of facial trauma. The objective of this study was to understand the factors associated with the restoration of mastication, ocular, and nasal functions in the face of trauma victims, estimating their recovery time after surgical treatment. We analyzed 114 medical records of patients treated at the Hospital Montenegro, who attended follow-up consultations for up to 180 days. For analysis of the recovery time, we performed survival analysis, followed by COX analysis. We observed that half of the patients recovered their functions within 20 days. The average time for recovery from trauma in the zygomatic-orbital-malar-nasal complex was 11 days, and in the maxillary-mandibular complex, 21 days (HR: 1.5 [0.99 2.3], p = 0.055). Although functional reestablishment has reached high rates after the surgical approach, it is necessary to analyze the failing cases, as well as the economic impacts and the prevention strategies associated with facial trauma, to improve the service to the population.


RESUMO O entendimento da causa, da gravidade e do tempo decorrido para o restabelecimento das funções de lesões maxilofaciais pode contribuir para o estabelecimento de prioridades clínicas objetivando o efetivo tratamento e prevenção dos traumatismos de face. Assim, o objetivo deste estudo foi compreender quais os fatores associados ao restabelecimento das funções mastigatórias, oculares e nasais em vítimas de trauma de face, estimando o tempo para recuperação das funções, após o tratamento cirúrgico. Foram analisados 114 prontuários de pacientes atendidos no Hospital de Montenegro que compareceram às consultas de acompanhamento por até 180 dias. Para a análise do tempo para a recuperação, foi realizada a análise de sobrevida, seguida da análise de COX. Observou-se que metade dos pacientes recuperaram as funções em até 20 dias, sendo que o tempo médio para recuperação dos traumas no complexo zigomático-orbitário-malar-nasal foi de 11 dias e do complexo maxilo - mandibular de 21 dias (HR: 1,5 (0,99 - 2,3) p=0,055). Embora o restabelecimento das funções tenha atingido taxas elevadas após abordagem cirúrgicas, faz-se necessária a análise dos casos de insucessos bem como os impactos econômicos e as estratégias de prevenção associados aos traumas de face a fim de qualificar o serviço prestado à população.

ABSTRACT

RESUMEN: Las fracturas panfaciales son aquellas que afectan de forma simultánea al tejido óseo de dos o más tercios del rostro. El manejo inicial de estos pacientes es resolver o estabilizar las urgencias médico - quirúrgicas que puedan presentar, debido a que la gran mayoría de estas fracturas están asociadas a traumatismos de alta energía cinética, las que determinan la presencia de lesiones concomitantes que pueden comprometer la vida del paciente. El tratamiento quirúrgico de las fracturas panfaciales puede abarcar desde la intervención quirúrgica inicial de control de daños, estabilización, reducción y fijación quirúrgica de los segmentos fracturados mediante osteosíntesis hasta intervenciones mediatas para la reconstrucción de los tejidos afectados por el traumatismo. Para el tratamiento de las fracturas panfaciales existe una sistemática quirúrgica que tiene por objeto contener y/o minimizar daños agudos y permitir una reducción morfológica y funcional. Reportamos un caso clínico de fractura panfacial cuyo tratamiento siguió esta sistemática terapeútica.


ABSTRACT: Panfacial fractures affect bone tissue in two or more thirds of the face simultaneously. The initial management of these patients is to resolve or stabilize the medical-surgical emergencies that they may present. Most of these fractures are associated to trauma of high kinetic energy, which determine the presence of concomitant inju- ries that can compromise the life of the patient. The surgical treatment of panfacial fractures may include from the initial surgical intervention of damage control, stabilization, reduction and surgical fixation of fractured segments through osteosynthesis, to mediate the reconstruction of tissues affected by the trauma. For the treatment of panfacial fractures there is a surgical approach that aims to contain and/or minimize acute damage and allow for morphological and functional reduction. We report a clinical case of panfacial fracture whose treatment followed this therapeutic approach.

ABSTRACT

Trans-sutural distraction is a biological process that induces the formation of new bone and changes the position of bone by pulling on growing suture under the action of external forces. Currently, therapy to midfacial hypoplasia treated by trans-sutural distraction has been applied. In this study, Beagle dogs were selected as experimental animals, and a traction device designed by ourselves was applied to Beagle dogs to simulate the treatment process of trans-sutural distraction in human face, so as to provide a basis for the subsequent research on the related mechanism of trans-sutural distraction. The objective is that the animal model can provide the basis for the follow-up study of transsutural distraction. 45 month beagle dogs were randomly divided into two groups 3 in experiment group and 3 in control group. Implant nails were implanted as the bone marker in the bilateral zygomatic temporal suture, zygomandibular maxillary suture and palatine transverse suture in experimental group. The traction of the maxilla was carried out by the external cranial traction frame with canine fossa as bearing point, 800g force each side, elastic traction for 15 days. The control group only implanted the implant nail as the bone marker on both sides of the bone suture. The distance between two implant nails was measured by vernier calipers and X-ray examination, compared with preoperative and postoperative changes. X-ray and cephalometric measurements were used to measure change in the cranial basal angle. HE staining was used to observe the width of the bone seams, the morphology and structure of the cells and the tissue of the new bone under the phase contrast microscope. Then descriptive statistical analysis and t-test between two independent samples are carried out for the measurement data. The experimental group had a good retention of the beagle traction frame. In the experimental group, the maxillaries of dogs were protrudent in the process of traction gradually and the occlusal relationship changed to type II malocclusion. When the traction is 15 days, the coverage distance is about 8~9 mm. Before and after the traction, the distance between landmark points indicated that the spacing between the transverse palatine suture was the largest (experimental group: 5.52±0.19 mm control group 1.31±0.06 mm P<0.05), and zygomaticotemporal suture was the second (experimental group: 3.12±0.15 mm, control group 0.73±0.04 mm, P<0.05), and zygomaticomaxillary suture was less (experimental group: 2.60±0.34 mm, control group 0.53±0.05 mm, P<0.05). The cranial basal angle was no change before and after operation (controlgroup: 32.3±1.3°, experimental group: 33.2±1.1° P>0.05. Histology showed that the collagenous fibers in the suture of the control group were denser and the osteoblasts were visible on the edge of the suture, showing osteogenic activity. The experimental group significantly widened suture (experimental group: 1209.388±42.714 µm, control group 248.276±22.864 µm, P<0.05), the number of fibroblasts increased significantly with loose collagen fiber. The direction of cell and fiber arrangement were parallel to the traction force. There were many small blood vessels and marrow cavities, and the bone trabecula around the bone suture was thin (experimental group: 23.684±3.774 mm, control group: 86.810±9.219 mm, P < 0.05), showing active osteogenic activity. The growing beagle dog can be used to establish a suture traction animal model for experimental study. In the experiment, Kirschner wire was used to penetrate the bottom plane of the piriform hole of the maxilla (about the position of the canine fossa at the back) and the traction direction was basically the same as the growth direction, and the maxilla was basically parallel and moved forward.


La distracción trans-sutural es un proceso biológico que induce la formación de hueso nuevo y cambia la posición del éste al tirar de la sutura en crecimiento bajo la acción de fuerzas externas. Actualmente, se ha aplicado la terapia para la hipoplasia de la cara media tratada por distracción trans-sutural. En este estudio, fueron seleccionados perros Beagle como animales experimentales, y un dispositivo de tracción fue instalado a los perros para simular el proceso de tratamiento de la distracción trans-sutural en el rostro humano. El objetivo fue proporcionar una base para la investigación posterior sobre mecanismos relacionados con la distracción trans-sutural. El modelo animal puede proporcionar la base para este tipo de estudio de seguimiento de la distracción trans-sutural. Perros Beagle de 45 meses de edad se dividieron aleatoriamente en dos grupos: 3 en el grupo experimental y 3 en el grupo control. Los clavos de implante se usaron como marcadores óseos en la sutura temporal cigomática bilateral, la sutura maxilar cigomandibular y en la sutura transversal palatina en el grupo experimental. La tracción del maxilar se realizó mediante el marco de tracción craneal externo con fosa canina como punto de apoyo, 800 g de fuerza a cada lado, tracción elástica durante 15 días. En el grupo control solo se implantó el clavo del implante como marcador óseo en ambos lados de la sutura. La distancia entre dos clavos de implante se midió mediante calibradores de vernier y examen de rayos X, en comparación con los cambios preoperatorios y postoperatorios. Se utilizaron mediciones cefalométricas y de rayos X para medir el cambio en el ángulo basal craneal. La tinción con HE se usó para observar el ancho de las suturas óseas, la morfología y la estructura de las células y el tejido del hueso nuevo bajo el microscopio de contraste de fase. Luego se realizó un análisis estadístico descriptivo y una prueba t entre dos muestras independientes para los datos de medición. El grupo experimental tuvo una buena retención del cuadro de tracción del Beagle. En el grupo experimental, los maxilares de los perros sobresalieron gradualmente en el proceso de tracción y la relación oclusal cambió a maloclusión tipo II. Cuando la tracción era de 15 días, la distancia de cobertura fue de aproximadamente 8 ~ 9 mm. Antes y después de la tracción, la distancia entre los puntos de referencia indicaba que el espacio entre la sutura palatina transversal era más grande (grupo experimental: 5,52 ± 0,19 mm, grupo de control 1,31 ± 0,06 mm, P <0,05), y la sutura cigomáticotemporal fue la segunda. (Grupo experimental: 3,12 ± 0,15 mm, grupo control 0,73 ± 0,04 mm, P <0,05), y la sutura cigomaticomaxilar fue menor (grupo experimental, 2,60 ± 0,34 mm, grupo control 0,53 ± 0,05 mm, P <0,05). El ángulo basal craneal no cambió antes ni después de la operación (grupo control 32,3 ± 1,3, grupo experimental, 33,2 ± 1,1 ° , P> 0,05). La histología mostró que las fibras colágenas en la sutura del grupo control eran más densas y los osteoblastos se observaron en el margen de la sutura, mostrando actividad osteogénica. En el grupo experimental se amplió significativamente la sutura (1209,388 ± 42,714 µm, grupo control 248,276 ± 22,864 µm, P <0,05), el número de fibroblastos aumentó significativamente con fibras colágenas dispersas. La dirección de la disposición de la celda y las fibras era paralela a la fuerza de tracción. Se observó gran cantidad de vasos sanguíneos pequeños, cavidades medulares, y trabéculas óseas alrededor de la sutura ósea (grupo experimental: 23,684 ± 3,774 mm, grupo control: 86,810 ± 9,219 mm, P <0,05), que mostró actividad osteogénica activa. El perro Beagle en crecimiento se puede utilizar para estudios experimentales y así establecer un modelo animal de tracción de sutura. En el proceso, se usó alambre de Kirschner para penetrar en el plano inferior del foramen piriforme del maxilar (aproximadamente en la posición de la fosa canina en la parte posterior) y la dirección de tracción fue básicamente la misma que en el crecimiento.

ABSTRACT

RESUMEN: Objetivo: Determinar las dimensiones de la cresta ósea vestibular de los incisivos maxilares con indicación de implantación inmediata. Pacientes y método: Un estudio transversal fue realizado en pacientes con necesidad de colocación de implantes inmediatos unitarios en la zona incisiva superior, durante el periodo de Enero-2015 a Diciembre-2017. Cortes tomográficos sagítales fueron utilizados para determinar la altura y el grosor de la cresta ósea alveolar vestibular. El punto de medición del grosor fue localizado a 4 mm apical a la linea amelocementaria. Un análisis T-student, fue utilizado para comparar las variables según la edad, el género y el grupo dentario, con un intervalo de confianza de 95%. Resultados: 298 imágenes fueron incluidas en la evaluación. El promedio de altura fue 10,68 mm, no hubo diferencias al comparar los grupos. El grosor promedio fue de 0,73 mm, diferencias de grosor, estadísticamente significativas, fueron observadas al comparar la edad y el género, no así en el grupo dentarlo. Conclusiones: La altura del hueso alveolar vestibular de incisivos superiores es suficiente para colocar implantes inmediatos dentro de un marco óseo. No obstante, el grosor observado, se traduciría en la necesidad de complementar la implantación con técnicas de regeneraciónn tisular guiada.


ABSTRACT: Objective : Determine the dimensions of the facial bone ridge of the maxillary incisors with indication of immediate implantation. Patients and method: A cross-sectional study was carried out in patients in need of single immediate implant placement in the upper incisor area, during the period from January-2015 to December-2017. Sagittal tomographic sections were used to determine the height and thickness of the vestibular alveolar bone ridge. The thickness measurement point was located 4 mm apical to the amelocementary junction. A T-student analysis was used to compare the variables according to age, gender, and dental group, with a 95% confidence interval. Results: 298 images were included in the evaluation. The mean height was 10.68 mm, there were no differences when comparing the groups. The mean thickness was 0.73 mm, statistically significant differences in thickness were observed when comparing age and gender, but not in the dental group. Conclusions: The height of the vestibular alveolar bone of the upper incisors could be sufficient to place immediate implants within a bone framework. However, the thickness observed would result in the need to complement the implantation with guided tissue regeneration techniques.

ABSTRACT

As fraturas panfaciais acometem concomitantemente os terços superior, médio e inferior da face, decorrentes de acidentes automobilísticos, arma de fogo, atropelamento, agressão física, entre outros. Essas fraturas geralmente envolvem osso frontal, zigomático, maxila, mandíbula e ossos nasais, necessitando assim, fixação interna rígida através do uso de miniplacas e parafusos com o propósito de estabilizar as estruturas fraturadas, dar suporte aos tecidos moles e evitar deformidades estéticas da face. O objetivo deste trabalho é relatar o manejo cirúrgico de um caso clinico atendido em um hospital público de Salvador/BA, no qual a vítima apresenta ampla laceração na face e fratura exposta do terço médio da face. O tratamento executado sob anestesia geral foi redução dos cotos ósseos fraturados, fixação com miniplacas e parafusos, reconstrução imediata dos tecidos moles acometidos(AU)


Panfacial fractures affect concomitantly the upper, middle, lower third of the face, resulting from automobile accidents, firearms, hit-and-run, physical aggression, among others. These fractures usually involve frontal bone, zygomatic, maxilla, jaw and nasal bones, thus requiring rigid internal fixation through the use of miniplates and screws in order to stabilize fractured structures, support soft tissues avoiding aesthetic face deformities. The objective of this work is to report the surgical management of a clinical case attended in a public hospital in Salvador/BA, in which the victim has wide laceration of the face and exposed fracture of the middle third of the face. Treatment performed under general anesthesia was reduction of fractured bone stumps, fixation with miniplates and screws, immediate reconstruction of the affected soft tissues(AU)

ABSTRACT

El hueso cigomático, ubicado en la parte superior y lateral de la cara, es un hueso par e irregular con forma cuadrilátera o romboidal. Se describen 2 caras, 4 aristas y 4 ángulos, forma cavidades, permite la inserción muscular y aponeurótica, es parte de la arquitectura facial, distribuye las fuerzas masticatorias y permite el paso del nervio cigomático. Su margen postero-superior presenta una prominencia ósea conocida como tubérculo marginal, en el que se observa la inserción de la fascia temporal. El objetivo de este trabajo fue describir las características particulares de esta prominencia. La muestra correspondió a 30 cráneos de adultos chilenos de ambos sexos. A través de una serie de puntos óseos, se describió la presencia, ubicación, tamaño, forma, cortical y trabeculado del tejido óseo del tubérculo marginal. Para realizar las mediciones se utilizaron cámara digital, compas de precisión y cáliper digital. El análisis radiográfico requirió tomografía computarizada de alta resolución. Los resultados mostraron que el tubérculo marginal del hueso cigomático es una prominencia constante, ubicada en el tercio medio del proceso frontal del hueso y que la mayoría de los individuos mostraron una forma semilunar. Su altura fluctúa entre 3 y 4 mm, siendo más pronunciada en hombres que en mujeres. El grosor de la corteza ósea es directamente proporcional a la prominencia del tubérculo, mientras que el trabeculado esponjoso está inversamente relacionado con este último. El análisis de estos resultados parece indicar que las fuerzas biomecánicas ejercidas por la musculatura masticatoria y transmitidas por la fascia temporal, determinan la morfología externa e interna de esta prominencia y del propio hueso cigomático. Concluimos, declarando la necesidad de revisar el conocimiento anatómico a la luz de las nuevas técnicas de imagen e integración disciplinar.


The zygomatic bone, located in the upper and lateral area of the face, is an even and irregular quadrilateral or rhomboid shaped bone. It presents 2 faces, 4 margins and 4 angles. It forms cavities, allows muscular and aponeurotic insertion, is part of the facial architecture, distributes masticatory forces and allows the passage of the zygomatic nerve. Its postero-superior margin presents a bony prominence known as a marginal tubercle, in which the insertion of the temporal fascia is observed. The objective of this work was to describe the particular characteristics of this prominence. The sample corresponded to 30 skulls of Chilean adults of both sexes. Through a series of bone points, the presence, location, size, shape, cortical and trabeculate of the bone tissue of the marginal tubercle was described. A digital camera, precision compass and digital caliper were used to perform the measurements. The radiographic analysis required high-resolution computed tomography. The results showed that the marginal tubercle of the zygomatic bone is a constant prominence, located in the middle third of the frontal process of the bone and that most individuals showed a semilunar shape. Its height fluctuated between 3 and 4 mm, being more pronounced in men than in women. The thickness of the bone cortex was directly proportional to the prominence of the tuber, while the spongy trabeculate was inversely related to the latter. The analysis of these results seems to indicate that the biomechanical forces exerted by the masticatory musculature and transmitted by the temporal fascia, determine the external and internal morphology of this prominence, and of the zygomatic bone itself. In conclusion, it is recommended to review anatomical knowledge in the light of new imaging techniques and disciplinary integration.

Introduction: To perform face length measurements on radiographs of Brazilian children from birth to one year of age in order to determine radiographic parameters of normality. Materials and Methods: We performed a retrospective analysis of simple skull radiographs for face measurement of children up to 12 months of age taken in a southern Brazilian hospital between 2013 and 2018. In total, 170 skull radiographs of 85 children under one year of age were included in the study. Measurement parameters were defined, then performed by three evaluators, and later compared using intraclass correlation coefficient and analysis of variance. Results: The intraclass correlation coefficient was high, demonstrating interexaminer agreement and reproducibility of the measurements. There was a small standard deviation between the measurements obtained from the different age groups. In general, there was a statistically significant growth of the face from the first to the third trimester. The growth was smaller and with no statistically significant difference from the third to the fourth trimester. Conclusion: We observed a progressive increase in the dimensions of the facial bones with growth in the first year of life, especially in the first 9 months. Obtaining these data will assist in the assessment of normality for this age group. (AU)

ABSTRACT

BACKGROUND: The big data provided by Health Insurance Review and Assessment (HIRA) contains data from nearly all Korean populations enrolled in the National Health Insurance Service. We aimed to identify the incidence of facial fractures and its trends in Korea using this big data from HIRA.METHODS: We used the Korean Standard Classification of Disease and Cause of Death 6, 7 for diagnosis codes. A total of 582,318 patients were included in the final analysis. All statistical analyses were performed using SAS software and SPSS software.RESULTS: The incidence of facial fractures consistently declined, from 107,695 cases in 2011 to 87,306 cases in 2016. The incidence of facial fractures was the highest in June 2011 (n = 26,423) and lowest in January 2014 (n = 10,282). Nasal bone fractures were the most common, followed by orbit and frontal sinus fractures. The percentage of nasal bone fractures declined, whereas those of orbital fractures increased from 2011 to 2016 (P < 0.001). Among orbital fractures, inferior wall fractures were the most common, followed by medial wall fractures. Among mandibular fractures, angle fractures were the most common, followed by condylar process and symphysis fractures. Although it was difficult to predict the most common type of zygomatic and maxilla fractures, their incidence consistently declined since 2011.CONCLUSION: We observed trends in facial fractures in Korea using big data including information for nearly all nations in Korea. Therefore, it is possible to predict the incidence of facial fractures. This study is meaningful in that it is the first study that investigated the incidence of facial fractures by specific type.

ABSTRACT

Objetivo: O presente estudo consiste em relatar o caso clínico de um paciente com fratura panfacial e abordagem cirúrgica de emergência para realização de fixação interna rígida e sua reabilitação. Descrição do Caso: Paciente do gênero masculino, 46 anos, vítima de acidente automobilístico, deu entrada no serviço de emergência do Hospital Geral do Estado da Bahia (HGE-BA) cursando com múltiplas fraturas em face. Foi planejada abordagem, sob anestesia geral e intubação orotraqueal com derivação submentual, em razão de fratura de base anterior de crânio, fratura dos ossos próprios nasais e necessidade de bloqueio maxilomandibular no transcirúrgico. Paciente acompanhado no pós-operatório, evoluindo com projeção facial satisfatória, oclusão estável, boa permeabilidade nasal e sem deformidade dentofacial. Conclusão: As fraturas panfacias são desafiadoras, e seu planejamento cirúrgico deve ser estabelecido visando o posicionamento adequado dos fragmentos fraturados e a preservação das estruturas anatômicas faciais, devolvendo função e garantindo o mínimo de sequelas para o paciente(AU)


Purpose: The present study consists in reporting the clinical case of a patient with panfacial fracture, with an emergency surgical approach to perform rigid internal fixation for patient rehabilitation. Case description: A 46-year-old male patient, victim of an automobile accident, was admitted to the emergency department of the Hospital Geral do Estado da Bahia (HGE-BA), attending multiple fractures in the face. The approach was planned under general anesthesia and orotracheal intubation with submental shunt, due to anterior skull fracture, fracture of the nasal bones and the need for maxillomandibular block in the trans-surgical. Patient followed postoperatively, evolving with satisfactory facial projection, stable occlusion, good nasal permeability, and no dentofacial deformity. Conclusions: Panfacial fractures are challenging, and their surgical planning must be established aiming at the adequate positioning of fractured fragments and preservation of facial anatomical structures, restoring function and ensuring a minimum of sequelae for the patient(AU)

ABSTRACT

ABSTRACT Introduction: regional epidemiological studies involving facial trauma are needed to develop more efficient ways of providing health care services. The time elapsed from the occurrence of facial trauma to its definitive treatment can affect clinical outcomes in terms of interventions, resolution, and complications. The aim of this study was to verify if there is a relationship between the different fracture types, their treatments or time intervals for clinical resolution and the onset of complications. Methods: a retrospective study was conducted by means of the clinical records of the Eugenio Espejo Hospital in Quito, verifying the epidemiological data on the clinical evolution of facial trauma patients between 2012 and 2016, and registering data such as age, gender, fracture type, time elapsed until its definitive treatment, and onset of complications. Clinical records lacking these data were excluded. Results: most cases occurred outside Quito (64%). There was no relationship between harmful habits, fracture displacement, type of access or fixation, or presence of comorbidities and the onset of complications. The odds ratio (95% confidence interval) for complications was OR = 0.301(0.170-0.536), so there is a 70% increased chance of developing some complications if treatment is performed one week after trauma occurs. Conclusion: reducing facial fractures before a week can decrease the onset of complications and sequelae.


RESUMEN Introducción: los estudios epidemiológicos regionales que involucren trauma facial son importantes para ayudar a desarrollar formas más eficientes de brindar cuidados en salud. El tiempo transcurrido desde que ocurre un traumatismo facial hasta su tratamiento definitivo puede afectar los resultados clínicos en términos de intervenciones, resolución y complicaciones. El objetivo del presente estudio consistió en verificar si existe una relación entre los diferentes tipos de fracturas, sus tratamientos y los intervalos de tiempo para su resolución clínica con la aparición de complicaciones. Métodos: se realizó un estudio retrospectivo con las historias clínicas del hospital Eugenio Espejo de Quito, verificando los datos epidemiológicos de la evolución clínica de pacientes con trauma facial entre el 2012 y 2016. Para ello se tomaron datos como edad, sexo, tipo de fractura, tiempo transcurrido hasta su tratamiento definitivo y aparición de complicaciones. Se descartaron las historias que no tuvieron todos los datos para este trabajo. Resultados: la mayoría de los casos ocurrió fuera de Quito (64%). Se observó que no existe relación entre hábitos nocivos, desplazamiento de fractura, tipo de abordaje o de fijación y presencia de comorbilidades con la aparición de complicaciones. El resultado de razones de probabilidad (intervalo de confianza) para las complicaciones fue de OR=0.301(0.170-0.536); por lo tanto, existe un 70% más de probabilidad de presentar alguna complicación si el tratamiento se realiza después de una semana de ocurrido el trauma. Conclusión: la reducción de las fracturas faciales antes de una semana puede disminuir la ocurrencia de complicaciones y secuelas.

ABSTRACT

Trauma in the modern society is characterized by multiple injuries, and the several comorbidities are often accompanied by facial bone fracture. The types of multiple facial bone fractures vary from Le Fort to panfacial fracture. Le Fort fracture, which can cause problems, such as facial disfigurement, functional impairment of mastication, malocclusion and speech abnormalities, is a challenging case for plastic surgeons. The purpose of treatment for patients with malocclusion due to Le Fort fracture is to maintain and restore both function and aesthetics. The author reports a case of Le Fort I osteotomy as a surgical correction of traumatic class III malocclusion due to Le Fort III fracture.

ABSTRACT

Fibromyxomas are uncommon, tenaciously infiltrative neoplasms that infrequently appear in the facial bones and paranasal sinuses. The neoplasms are slow growing and result in expansion of the surrounding bony cortices. In the present study, we report an extremely rare case of antrochoanal fibromyxoma that occluded the ostiomeatal complex and originated from the maxillary sinus inferior wall. Initially, the neoplasm was suspected to be a nasal polyp. However, after endoscopic sinus surgery, the neoplasm was diagnosed as fibromyxoma based on histopathology.

ABSTRACT

BACKGROUND: Sometimes general anesthesia is required for dental surgery in pregnant women. Facial bone fractures or neck abscess should be treated immediately. Dental surgery, however, creates a stressful situation that can cause inflammation. Inflammatory responses are a well-known major cause of preterm labor and preterm birth. Here we demonstrate the effects of remifentanil on the factors related to preterm labor and its mechanism of action on amniotic-derived epithelial cells (WISH cells). METHODS: WISH cells were exposed to lipopolysaccharide (LPS) for 24 h and co-treated with various concentrations of remifentanil. MTT assays were performed to measure cell viability. To explain the effects of remifentanil on the factors related to inflammation in WISH cells, activation of nuclear factor kappa B (NF-κB) and p38 and the expression of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, cyclooxygenase (COX)2, and prostaglandin E (PGE)2 were quantified using western blotting and RT-PCR, respectively. RESULTS: Remifentanil did not affect WISH cell viability. In western blot analysis, co-treatment with remifentanil resulted in decreased phosphorylation of NF-κB, and expression of COX2 and PGE2 in LPS-induced inflammation, but the results were statistically significant only at low concentrations. Reduction of IL-1β and TNF-α expression was also observed with RT-PCR. CONCLUSION: Co-treatment with remifentanil does not affect the viability of WISH cells, but reduces the expression of the factors related to inflammation, which can induce uterine contraction and preterm labor. These findings provide evidence that remifentanil may inhibit uterine contraction and preterm labor in clinical settings.

ABSTRACT

BACKGROUND: Closed reduction of nasal fracture with various instrument is performed to treat nasal fracture. Depending on the type of nasal fracture and the situation in which it is being operated, the surgeon will determine the surgical tool. The objective of this study was to investigate whether a periosteal elevator (PE) was a proper device to perform closed reduction for patients with simple nasal fractures. METHODS: From March 2018 to December 2018, 50 cases of simple nasal bone fracture underwent closed reduction performed by a single surgeon. These patients were divided into two groups randomly: nasal bone reduction was performed using only PE (freer) and nasal bone reduction was performed using Walsham, Asch forcep, and Boies elevator (non-freer, non-PE). RESULTS: The paranasal sinus computed tomography was performed on patients before and after operation to carry out an accurate measurement of reduction distance at the same level. According to the results, the interaction between instruments and fracture types had a significant influence on reduction distance (p = 0.021). To be specific, reduction distance was significantly (p= 0.004) increased by 2.157 mm when PE was used to treat patients with partial displacement compared to that when non-PEs were used. CONCLUSION: Closed reduction using PE and other elevator is generally an effective treatment for nasal fracture. In partial-displacement type of simple nasal fracture, closed reduction using PE can have considerable success in comparison with using classic instruments.

ABSTRACT

BACKGROUND: Absorbable plates are widely used in open reduction and internal fixation surgeries for facial bone fractures. Absorbable plates are made of polyglycolic acid (PGA), polylactic acid (PLA), polydioxane (PDS), or various combinations of these polymers. The degradation patterns of absorbable plates made from different polymers and clinical courses of patients treated with such plates have not been fully identified. This study aimed to confirm the clinical courses of facial bone fracture patients using absorbable plates and compare the degradation patterns of the plates. METHODS: A retrospective chart review was conducted for 47 cases in 46 patients who underwent open reduction and internal fixation surgery using absorbable plates to repair facial bone fractures. All surgeries used either PLA/PGA composite-based or poly-L-lactic acid (PLLA)/hydroxyapatite (HA) composite-based absorbable plates and screws. Clinical courses were confirmed and comparisons were conducted based on direct observation. RESULTS: There were no naturally occurring foreign body reactions. Post-traumatic inflammatory responses occurred in eight patients (nine cases), in which six recovered naturally with conservative treatment. The absorbable plates were removed from two patients. PLA/PGA composite-based absorbable plates degraded into fragments with non-uniform, sharp surfaces whereas PLLA/HA composite-based absorbable plates degraded into a soft powder. CONCLUSION: PLA/PGA composite-based and PLLA/HA composite-based absorbable plates showed no naturally occurring foreign body reactions and showed different degradation patterns. The absorbable plate used for facial bone fracture surgery needs to be selected in consideration of its degradation patterns.

ABSTRACT

Intraorbital infection shows a low incidence, but it might cause blindness or even death. This case is unusual in that its origin from a craniofacial bone fracture prior to infection of the maxillary sinus. A 33-year-old female patient was referred for right cheek swelling. When she visited the emergency room, we removed right cheek hematoma and bacterial examination was done. In the past, she had craniofacial bone surgical history due to a traffic accident 6 years ago. Next day, the swelling had remained with proptosis and pus was recognized in the conjunctiva. We planned an emergency operation and removed the pus which was already spread inside the orbit. And the evaluation for sinusitis was consulted to the otorhinolaryngology department simultaneously. There were Prevotella oralis and methicillin-resistant Staphylococcus epidermidis bacterial infection in the intraorbital and sinus respectively. Afterwards, the vigorous dressing was done for over a month with intravenous antibiotics. Though the intraorbital infection was resolved, blindness and extraocular movement limitation were inevitable. In conclusion, close follow up of the maxillary sinus in facial bone fracture patients is important and aggressive treatment is needed when an infection is diagnosed.
