ABSTRACT
Para el tratamiento de fracturas mandibulares existen protocolos cuyo propósito primordial es la función temprana. Existen diversos motivos por los cuales no se puede ejecutar ciertas técnicas en Venezuela, principalmente por problemas económicos para la adquisición de materiales de osteosíntesis especializados. Por esta razón, se ha recurrido a técnicas quirúrgicas antiguas. Se presenta un estudio con diseño longitudinal de tipo descriptivo, para el reporte de serie de 5 casos clínicos de fracturas de mandíbula, con los siguientes criterios de inclusión: presentar fractura mandibular en pacientes dentados parcialmente con imposibilidad al acceso al material de osteosíntesis del sistema de cargas soportadas. Tratados bajo procedimiento quirúrgico cerrado, la condición de edentulismo parcial confiere a la fractura de mandíbula inestabilidad, dificulta la reducción anatómica, pérdida de dimensión vertical y transversal, las que se recuperan a través de la elaboración de férulas tipo Gunning modificadas. Estas férulas se mantuvieron en posición con alambrados de suspensión ósea tipo circummandibulares y circumzigomáticos, como medios para establecer estabilidad en el tiempo. Se obtuvieron resultados satisfactorios, por lo que, aún hoy en día se pueden plantear como opciones de tratamiento.
For the treatment of mandibular fractures, there are protocols whose primary purpose is early function. However, several reasons prevent the execution of these techniques in Venezuela, mainly due to economic problems regarding the acquisition of specialized osteosynthesis materials. As a result, there is a necessity to resort to old surgical techniques. A study with a descriptive longitudinal design is presented, reporting 5 clinical cases of jaw fractures with the following inclusion criteria: presenting a mandibular fracture in partially dentate patients with impossibility of accessing the osteosynthesis material of the load-bearing system. The treatment conducted under closed surgical procedures. The condition of partial edentulism confers instability to the mandible fracture, hindering anatomical reduction and causing a loss of vertical and transverse dimension. These issues are addressed through the utilization of modified Gunning-type splints, which help in recovery. The splints were maintained in position with circum-mandibular and circum-zygomatic bone suspension wiring as a means to establish stability over time. Satisfactory results were obtained, indicating that these techniques can still be considered as treatment options today.
ABSTRACT
Aim: Verify the accuracy of objective assessments compared to subjective tests in detecting changes in somatosensory perception in individuals affected by maxillofacial trauma. Methods: The review (PROSPERO n ° CRD42019125546) used the databases: MEDLINE, Cochrane, EMBASE, LILACS and other bibliographic resources. Prospective and retrospective studies that used objective and subjective methods of assessing facial sensitivity in maxillofacial fractures were included. There was no restriction on language or publication date. Risk of bias was assessed using the QUADAS-2. Data extraction and analysis were performed using a form developed for the study. Results: 21 studies were included. The clinical objective examination mainly includes assessments of: tactile sensitivity (95.24%) and nociceptive sensitivity (57.14%). The subjective assessment was based on the patient's report, spontaneously (61.90%), guided by structured questionnaires (33.33%) and/or using scales (9.52%) to measure the degree of impairment. In risk of bias assessment, were observed no adequate interpretation and classification of changes in subjective sensitivity, subject to inappropriate analysis of the data. In addition, the studies bring several instruments without standardization for assessing sensory modalities. Conclusion: The objective assessment is a complement to the subjective assessment, using the touch assessment as the main parameter in the profile of the facial peripheral integrity, associated or not with nociceptive assessment. Lack of consensus on the indication of specific instruments for testing is a limiting factor. Thus, based on the studies, is proposed a minimum battery of sensitivity assessment to obtain an overview of the patient's peripheral nervous situation

Objective @#To explore the effects of mouth floor approach intubation in the treatment of jaw fracture combined with skull base injury.@*Methods @#From Jan. 2014 to Oct. 2015, 7 cases of jaw fracture combined with skull base injury were selected from Medical center of Stomatology, Foshan Hospital of Traditional Chinese Medicine (FSTCM). All cases were treated with mouth floor approach intubation, because they were not suitable to be given the oral or nasal intubation anesthesia. @*Results @#All the patients healed well after operation, and there was no tube accident or other complications.@*Conclusions@# For patients of jaw fracture combined with skull base injury, the mouth floor approach intubation could be recommended as a supplementary choice for traditional intubation methods.
ABSTRACT
Objective:To analyse the methord and effects of intermaxillary traction(IMT)screws used in the treatment of jaw frac-ture.Methods:In the treatment of 1 68 cases of jaw fracture IMT screws were used for the restoration of normal and stable occlusion. The screw number,position,traction effect and postoperative complications of the treatment were analysed.Results:705 screws were used in 168 patients,4 screws were used in each of 147 cased (88%),6 in 12(7%),5 in 9(5%).336(47.7%)screws were fixed between the roots of first and second premolar,292(41 .4%)between the roots of canine and first premolar,50 (7.1%)be-tween the roots of second premolar and first molar,27(3.8%)between the other tooth roots.Normal postoperative occlusion relation was achived by the use of screws in 92 cases without traction.Occlusion disharmony or deviation was found in 76 cases by the used of screws and was restored to normlal by 1 4-day traction in 71 cases.The total efficiency of the treatment was 97%.Pain of the mucosa surrounding the screws was observed in 23 cases (1 3.7%).Root damage,traction screw loosening and adjacent tooth dislocation were observed in 1 3(1 .8%),1 1 (1 .6%)and 2(0.3%)cases respectively.Conclusion:For the fixation of IMT screws,the posi-tions between tooth root from canine to first molar were most common and safe.The fixation point should be in 5 ~8mm below the gin-gival margin.Use of 4-6 screws can meet treatment need.
ABSTRACT
PURPOSE: To establish management protocol for mandibular angle fracture, we describe pertinent factors including cause, impacted third molar and recent treatment tendency. METHODS: We examined the records of 62 patients who had unilateral mandibular angle fracture. Sixty patients who had open reduction surgery were examined at postoperative weeks 1, 4, 8, 12, and 28. RESULTS: Left mandibular angle fracture is frequent in younger males. Presence of the mandibular third molar can increase fracture risk. Because of attached muscle, favorable fractures occurred primarily in the mandibular angle area. CONCLUSION: Extracting the mandibular third molar can prevent angle fractures, and open reduction with only one plate adaptation is generally the proper treatment method for mandibular angle fracture.

Objetivo: avaliar a incidência, as regiões mais afetadas, o manejo bem como as complicações encontradas em dentes envolvidos em linhas de fraturas mandibulares. Métodos: Os dados foram coletados a partir de prontuários de pacientes tratados com fraturas mandibulares. Foram incluídas informações como dados demográficos, localização da fratura, presença de dentes na linha de fratura e complicações. Resultados: a amostra apresentou um total de 310 linhas de fratura, e destas 144 tinham dentes envolvidos. a região mais afetada foi o ângulo, seguido da parassínfise, pelo corpo, pelo processo alveolar e pela sínfise. Observaram-se 196 dentes nas linhas de fraturas, 60 dos quais tinham sido retirados. Complicações pós-operatórias ocorreram em 8,6% da amostra. Dos casos que apresentaram complicações, pacientes sem dentes envolvidos na linha de fratura corresponderam a 43,75%, e os pacientes com dentes envolvidos na linha de fratura foram de 56,25%. Quando o dente foi removido, 8,47% dos pacientes apresentaram complicações, e, quando o dente foi mantido, 2,85%. Conclusão: este estudo demonstrou que a presença de dentes da linha de fratura não é um fator limitante para o tratamento. As complicações são mais frequentemente relacionadas com o método de tratamento escolhido do que para o envolvimento de dentes na linha de fratura.
Purpose: To examine the incidence, the regions most affected, the management as well as the complications found in teeth involved in the line of mandibular fractures. Methods: Data were collected from patients records treated of mandibular fractures. It was included information such as demographic data, fracture location, presence of teeth in the line of fracture, treatment and complications. Results: The sample has presented a total of 310 lines of fracture, from these, 144 had teeth involved. The most affected area was the angle, followed by the parasymphysis, body, alveolar process and symphysis. There were 196 "fracture line" teeth, 60 of which had been removed. Postoperative complications occurred in 8.6% of the sample. From the cases that presented complications, patients without teeth involved in the fracture line ranged 43.75% and patients with teeth involved in the fracture line reached 56.25%. When the tooth was removed 8.47% of the patients presented complications and when the tooth was retained 2.85%. Conclusion: This study demonstrated that the presence of teeth in the line of fracture is not a limiting factor for the treatment. The complications are more frequently related to the chosen method of treatment than to the involvement of teeth in the line of fracture.
ABSTRACT
As armas de fogo são largamente utilizadas para a prática de homicídios, suicídios e lesões corporais. Utilizadas pelas forças policiais em todo o mundo, provocam lesões caracterizadas por extensa destruição tecidual, cujo tratamento é complexo e requer, muitas vezes, grandes reconstruções. Na tentativa de controlar situações de agitação social, manifestações, tumultos ou depredações sem, contudo, matar ou ferir gravemente os participantes, a polícia vem utilizando armas de munição não letal. embora não letal, se a munição atingir partes delicadas do corpo, pode causar danos importantes ou, até mesmo, levar à morte da vítima. O objetivo deste trabalho foi relatar um caso clínico de um paciente atendido no Serviço de emergência do Hospital Municipal Salgado Filho/RJ-Brasil, vítima de fratura de mandíbula, em decorrência de uma agressão por projétil não letal bem como discutir a capacidade de morbidade dessas munições que, embora consideradas não letais, se incorretamente utilizadas, podem levar ao óbito.
Firearms are widely used for the practice of homicides, suicides and injuries. Used by police forces around the world, causing lesions characterized by extensive tissue destruction, whose treatment is complex and often requires, large reconstructions. In an attempt to control situations of social unrest, demonstrations, riots or vandalism without, however, kill or seriously injure the participants, the police have been using non-lethal weapons ammunition. While not lethal, if the ammunition reaches delicate parts of the body can cause serious damage or even lead to death of the victim. The aim of this study was to report a case of a patient treated at the emergency Service of the Salgado Filho Municipal Hospital / RJ-Brazil, victim of mandible fracture as a result of an assault by non-lethal projectile, as well as discuss the ability of morbidity this ammunition that, while considered non-lethal, if used incorrectly, can lead to death.
ABSTRACT
Maxillary and mandibular fractures account for a large proportion of facial bone fractures. The primary objective in reduction of marillary or mandibular fractures is to return the structures to normal position of function and cosmetic contour, i.e. restoration of normal occlusal relations through proper positioning of the teeth and bony structures. Interdental wiring, intermaxillary fixation, rigid internal fixation or external pin fixation are common methods in the management of jaw fractures, varying with the age of the patient, location or extent of fracture. Malocclusion is not an uncommon complication after management of jaw pacture. We managed 16 patients (13 males, 3 females) of mandibular or maxillary fractures with model surgery and occlusal splint from July 1998 to August 1999. The average age of patients was 27.4 years and the average follow-up period was 6 months. We achieved good occlusal relationship without malunion, nonunion, or loss of teeth. Acrylic occlusal splints are rigid, strong, easily adjusted and repaired, translucent, lightweight and tolerated well by the oral mucosa. It is useful in the maintenance of intermaxillary fixation and in maintaining continuity of the maxillary or mandibular dental arch, as well as providing precise dental alignment during healing. Splints are helpful in managing fractures of the symphysis, parasymphyseal region, body and alveolar ridges of the mandible, sagittal fractures of the hard palate, and severely comminuted mandible fractures.
