RESUMO

AIMS AND OBJECTIVES: To analyze and evaluate clinical features that define complex dentoalveolar trauma. MATERIALS AND METHODS: Forty-five patients, with a mean age of 36.1 years, were included in the study; most patients were male (82.2%). The main clinical features defining dentoalveolar fractures were evaluated, including the status of the tooth, alveolar socket and adjacent soft tissues and their relationships with tooth loss. The relationship between splinting and tooth loss was also studied. The data were analyzed using descriptive and statistical methods. RESULTS: A significant relationship was observed between the different clinical variables and tooth loss, in particular the status of the alveolar socket as the most relevant clinical factor; there was also a significant relationship between splinting and tooth loss, as this was the main protective factor. CONCLUSIONS: Tooth loss prognosis following complex dentoalveolar trauma is related to the clinical features of the fracture, particularly the status of the alveolar socket and the possibility of using splinting as treatment.

RESUMO

INTRODUCCIÓN: El colgajo peroneo es actualmente una de las técnicas más elegidas para la reconstrucción de defectos mandibulares. Muchos de los pacientes reconstruidos con este colgajo presentan patología oncológica que precisa tratamiento adyuvante con radioterapia. Los efectos adversos de la radioterapia sobre los tejidos son conocidos, pudiendo desembocar en osteoradionecrosis. El objetivo de este estudio es el análisis de la densidad ósea de los colgajos peroneos en los pacientes que han recibido radioterapia frente a los que no y su posible correlación con las complicaciones posteriores. MATERIAL Y MÉTODOS: Realizamos un estudio retrospectivo de los colgajos peroneos realizados por nuestro servicio desde enero 2011 hasta diciembre 2016. Los criterios de inclusión de los pacientes fue el haber sido reconstruidos con un colgajo peroneo y disponer de un TC de control a los tres meses postradioterapia en caso de haberla precisado. Se recogió la edad, densidad ósea peronea, desviación estándar cuerpo mandibular remanente y colgajo peroneo, así como las complicaciones postoperatorias. Los datos extraídos fueron analizados a través del Software SAS (Statistical Analisys System). RESULTADOS: En total se recogieron 61 pacientes, siendo la media de edad de 54,46 años. De estos 61 pacientes se excluyeron 11 al no presentar TC de control; de los 50 pacientes restantes, 27 recibieron tratamiento radioterápico adyuvante (54 %), mientras que 23 no la recibieron (46 %). En los pacientes irradiados, un alto porcentaje (84,62 %) recibieron altas dosis de radioterapia (> 60 Gy). Se encontraron diferencias estadísticamente significativas (p < 0,05) respecto a la edad y la desviación estándar de la densidad ósea del cuerpo mandibular remanente, mientras que en el resto de los parámetros no se encontraron diferencias estadísticamente significativas. Los pacientes irradiados presentaron un mayor porcentaje de complicaciones frente a los pacientes no irradiados, sin diferencias estadísticamente significativas. Discusión: Las nuevas técnicas de radioterapia de intensidad modulada permiten una dosis relativamente uniforme en un objetivo, evitando altas dosis en los tejidos circuncidantes. A pesar del avance en las técnicas de radioterapia, actualmente en la mayoría de centros se continúa realizando un tratamiento completo del volumen del lecho tumoral, que incluye en el campo de irradiación el colgajo con el que se reconstruye. Los casos de osteonecrosis mandibular que se presentaron fueron en pacientes irradiados y a nivel del cuerpo mandibular remanente. La densidad ósea a nivel del colgajo peroneo sí que presentó diferencias estadísticamente significativas en pacientes irradiados frente a no irradiados; este aspecto puede influir en el índice de complicaciones. CONCLUSIONES: Consideramos, con los resultados del estudio, plantear nuevos estudios prospectivos para valorar la necesidad de irradiar el tejido óseo del colgajo peroneo como parte del volumen del lecho tumoral, siendo que este tejido no ha estado en contacto con el tumor primario, ante el mayor índice de complicaciones asociados a la radioterapia en estos tejidos


INTRODUCTION: The fibular flap is currently one of the most chosen techniques for the reconstruction of mandibular defects. Many of the patients reconstructed with this flap present oncological pathology that requires adjuvant treatment with radiotherapy. The adverse effects of radiotherapy on tissues are known, and can lead to osteoradionecrosis. The aim of this study is to analyze the bone density of peroneal flaps in patients who have received radiotherapy against those who do not and their possible correlation with subsequent complications. MATERIAL AND METHODS: We designed a retrospective study of the fibular flaps performed by our service from January 2011 to December 2016. The criteria for inclusion of patients was to have been reconstructed with a peroneal flap and have a control CT at 3 months after radiotherapy. Age, bone density, standard deviation and further complications were extracted. The extracted data was analyzed through the SAS (statistical Analisys System) Software. RESULTS: 61 patients were collected; the mean age was of 54.46 years. Of these 61 patients were excluded 11 by not presenting control TC, of the 50 patients remaining, 27 received adjuvant radiotherapy treatment (54 %) while 23 did not receive (46 %). In irradiated patients a high percentage (84.62 %) received high doses of radiotherapy (> 60 Gy). Statistically significant differences were found (P < 0.05) with respect to age and standard deviation of bone density of the remaining mandibular body, while in the rest of the parameters no statistical significant differences were found. Irradiated patients presented a higher percentage of complications compared to non-irradiated patients without statistically significant differences. Discussion: The new techniques of intensity-modulated radiotherapy allow a relatively uniform dose in a target, avoiding high doses in the circumcising tissues. Despite the progress in radiotherapy techniques, currently in most centers, it continues to perform a complete treatment of the volume of the tumor bed that includes in the field of irradiation the flap with which it is reconstructed. The cases of mandibular osteonecrosis that were presented were in irradiated patients and in the remaining mandible. Bone density at the level of the fibular flap showed statistically significant differences in irradiated patients compared to non-irradiated, this aspect may influence in the index of complications. CONCLUSIONS: We consider to propose new prospective studies to assess the need to irradiate the bone tissue of the fibular flap as part of the volume of the tumor bed, knowing that this tissue has not been in contact with the primary tumor, and the high index of complications associated with radiotherapy

RESUMO

El objetivo de este trabajo es conocer las principales técnicas para el tratamiento de la ránula sublingual, llevando a cabo una revisión de la literatura existente a propósito de un caso clínico. Con respecto al caso clínico se trata de una paciente mujer de 20 años que acude a consulta por aumento de tamaño del suelo de la boca de unos 3x5 cm. Al realizar la resonancia magnética, se observa una lesión quística en la región sublingual derecha. Se planifica cirugía de escisión radical, extirpando la glándula sublingual derecha y la lesión. Se pauta como tratamiento antibiótico amoxicilina-ác. clavulánico 875/125 mg y antiinflamatorio metilprednisolona 40 mg y dexketoprofeno 50 mg. Como conclusión la técnica más utilizada, hoy en día, es la cirugía radical, seguida de la micromarsupialización y técnicas modernas mínimamente invasivas


The objective of this study is to know the main techniques for the treatment of the sublingual ranula, through a literature review about a clinical case. With regard to the clinical case, this is a 20 year old female patient present at medical clinic for an increase size of the floor of the mouth of about 3x5cm. When performing a magnetic resonance, observe a cystic lesion in the right sublingual region. Radical excision surgery planned, removing the right sublingual gland and the lesion. It is prescribed as antibiotic treatment amoxicillin-clavulanic acid 875/125 mg and anti-inflammatory methylprednisolone 40 mg and dexketoprofene 50 mg. In conclusion, the most used technique, nowadays, is the radical surgery, followed by the micromarsupialisation and minimally invasive modern technique
