Temporomandibular joint arthrocentesis guided by ultrasonography: An anatomical study.

The temporomandibular joint (TMJ) arthrocentesis is a common procedure in maxillofacial surgery departments for the treatment of TMJ dysfunction. The use of ultrasonography in this area is rare, and in the vast majority of cases only as a diagnostic, and non-therapeutic use. Through this study we propose the equipment and ultrasound parameters necessary to obtain detailed and practical images when using ultrasonography as a therapeutic guide in arthrocentesis of TMJ. In addition, we provide data regarding the placement and working angulations of both the ultrasound probe and the needle that are ideal for facilitating image-guided puncture. It is a simple technique, with a relatively short learning curve, and that can provide considerable intraoperative help to the surgeon.

Tomografía computarizada multidetector en el traumatismo facial: informe estructurado y observaciones clave para un abordaje sistemático / Multidetector computed tomography for facial trauma: structured reports and key observations for a systematic approach

Las fracturas faciales, relacionadas frecuentemente con accidentes de tráfico, agresiones, accidentes laborales o caídas, constituyen un considerable número de urgencias en nuestros hospitales y asocian, además, una elevada morbimortalidad. La tomografía computarizada multidetector es la técnica de imagen de elección por su amplia disponibilidad y rapidez, y porque permite tanto la caracterización de las fracturas faciales como de las complicaciones asociadas, incluyendo las de localización craneal. Es, por tanto, fundamental para orientar el manejo clínico y la planificación quirúrgica. En este trabajo se describe la anatomía radiológica de la región facial, destacando la importancia de los contrafuertes o arbotantes faciales, se ilustran los hallazgos característicos en las fracturas faciales, y se indican los puntos clave necesarios para su abordaje estructurado al realizar el correspondiente informe radiológico

Facial fractures, often related to traffic accidents, assault, work-related accidents, or falls, account for a considerable number of emergencies in our hospitals and are associated with high morbidity and mortality. Multidetector computed tomography (MDCT) is the imaging technique of choice in this scenario because it is widely available, fast, and useful for characterizing facial fractures and associated complications, including those located in the head. For all these reasons, MDCT is fundamental in the clinical management of these patients and in planning surgery. This paper describes the radiological anatomy of the facial region, underlining the importance of the facial buttresses, and it indicates the key points necessary for carrying out a structured approach and elaborating the corresponding radiologic report

Temporomandibular chronic dislocation: The long-standing condition.

BACKGROUND: The temporomandibular joint (TMJ) dislocation can be categorised into three groups: acute, habitual or recurrent and long-standing. The long-standing or protracted lower jaw dislocation refers to a condition that persists for more than one month without reduction. There are a great variety of methods for its treatment, from the manual or non-surgical, to surgical ones like the indirect approach (conservative surgical approach) and direct approach (open joint). Additional procedures in unsuccessful cases may include extra-articular orthognathic techniques to correct a malocclusion until joint replacement. MATERIAL AND METHODS: We report four new cases with a minimum of 6 weeks dislocation who were seen since 1995 to 2015 in the Maxillofacial Department of the Clínico Hospital (Valencia, Spain), in which the mean age was 57.5 years. Most of them were bilateral and the gender was predominantly female. Additionally, we have reviewed the related literature. RESULTS: All of the cases were successfully treated and half of them required open surgery. CONCLUSIONS: The report confirms the difficulty of the treatment and reaffirms the necessity to bear in mind the wide variety of methods available for the treatment of this pathology. We stress the difficulties associated with managing the treatment and of suggesting new guidelines. The best option still remains not to delay the diagnostic and to select the appropriate initial treatment.

Malformaciones venosas orofaciales de bajo flujo: esclerosis endoluminal con láser de diodo / Low-flow orofacial venous malformations: endoluminal sclerosis with a diode laser

Introducción: Las anomalías vasculares son procesos frecuentes que se localizan en más del 50% de los casos en la región de la cabeza y el cuello. Las técnicas clásicas de tratamiento, tales como la cirugía y la esclerosis química, han dado paso a modernas técnicas menos invasivas, tales como el láser Nd:YAG. Por otra parte, se ha utilizado con éxito el láser de diodo (980 nm) para el tratamiento de varices mediante esclerosis endoluminal. Nuestra propuesta es la utilización del láser de diodo (L 980 nm) para provocar una esclerosis por fotocoagulación intralesional de las malformaciones venosas de bajo flujo dada la capacidad de este láser de ser transmitido por fibra óptica. Objetivo: Exponer nuestros resultados en el tratamiento de malformaciones venosas de bajo flujo (MVBF) orofaciales mediante la terapéutica de esclerosis endoluminal con láser de diodo. Material y métodos: Revisamos 84 pacientes que presentaban MVBF orofaciales tratados con láser de diodo. Describimos la técnica de realización y se muestran los resultados postoperatorios a corto plazo. Resultados: Tras un periodo de seguimiento no inferior a 12 meses se constató curación en el 95,24% aplicando una o dos sesiones y solamente en 4 casos se objetivó recidiva. Concluimos que la técnica de esclerosis endoluminal con láser de diodo de MVBF en el área orofacial se constituye como una nueva técnica de tratamiento, mínimamente invasiva, ambulatoria, y que permite la resolución de los casos sin tener que recurrir a cirugías más agresivas y con excelentes resultados funcionales y estéticos(AU)

Background: Vascular anomalies are common processes that involve the head and neck region in more than 50% of the cases. Traditional treatment options such as surgery and chemical sclerosis have given way to modern less-invasive techniques, including Nd:YAG laser treatment. On the other hand, 980 nm laser diode has been successfully used for the endovenous sclerosis of varicose veins. Our proposal is the usage of diode laser ( L = 980 nm) to induce the sclerosis of low-flow venous malformations by intralesional photocoagulation, given this laser’s ability to deliver the beam via a fiber optic cable. Objective: To report our results in the treatment of orofacial low-flow venous malformations (LFVM) with diode laser endovenous sclerosis (DLES). Material and methods: The clinical records from 84 patients presenting with orofacial LFVM treated with DLES were collected. The technique used and short-term postoperative results were revised. Results: After a follow-up period of at least 12 months after one or two DLES sessions, healing was observed in 95.24% of the cases. Only 4 cases showed relapse. Conclusions: The DLES technique is a new therapeutic option for the treatment of orofacial LFVM, is minimally-invasive, allows an outpatient setting and achieves excellent functional and esthetic results avoiding more aggressive procedures(AU)

Férula quirúrgica intermedia en cirugía ortognática bimaxilar: un método simple de obtención / Intermediate surgical splint in orthognathic bimaxillary surgery. A simple method for obtaining it

La utilización de la férula quirúrgica intermedia (FQI) en las intervenciones de cirugía ortognática bimaxilar es un procedimiento habitual. La utilidad, ayuda y confianza que aporta es indiscutible. Sin embargo, el procedimiento clásico de obtención de la FQI es complejo. Proponemos simplificar la fabricación de la FQI sin renunciar a su precisión y fiabilidad. Debemos cuestionar algunos conceptos del método de obtención de esta férula y reflexionar sobre el siguiente concepto básico: la dimensión vertical craneomandibular preoperatoria es igual a la dimensión vertical craneomandibular postoperatoria con la férula en posición. Para confeccionarla se ha diseñado un nuevo dispositivo denominado: Posicionador del maxilar (AU)
