ABSTRACT

PURPOSE: The main objective of our study was to evaluate the effectiveness of the injection of plasma rich in platelet-derived growth factors (PRGF) versus hyaluronic acid (HA) following arthroscopic surgery in patients diagnosed with internal derangement of the temporomandibular joint (TMJ) with osteoarthritis (OA). MATERIALS AND METHODS: A total of 100 patients were randomised into two study groups. Group A (n = 50) received an injection of PRGF, and Group B (n = 50) received an injection of HA. The mean age was 35.5 years (range 18-77 years), and 88% of the patients were women. The pain intensity (visual analogue scale) and the extent of maximum mouth opening before and after the procedure were statistically analysed. RESULTS: Better results were observed in the group treated with PRGF, with a significant reduction in pain at 18 months, compared with HA treatment. Regarding mouth opening, an increase was observed in both groups, with no significant difference. CONCLUSIONS: The injection of PRGF following arthroscopy is more effective than the injection of HA with respect to pain in patients with advanced internal derangement of the TMJ.

ABSTRACT

Propósito. Comunicar un caso inusual de crecimiento tumoral agresivo en relación con el uso de distracción mandibular. La situación clínica presentada sugiere que los factores bioquímicos liberados durante la distracción ósea pueden interferir el desarrollo de los tumores malignos activos, provocando una rápida progresión. Material y métodos. Presentamos el caso de una paciente con antecedentes de carcinoma basocelular esclerosante recurrente en el área labiomentoniana izquierda. A pesar de los múltiples intentos de extirpar completamente el tumor y el estrecho seguimiento realizado, 18 años después de realizar el diagnóstico inicial las biopsias tomadas mostraron infiltración tumoral de la mandíbula. Con el fin de minimizar la cantidad de hueso y partes blandas necesarias para la reconstrucción, se decidió realizar una distracción mandibular bilateral antes de realizar la resección mandibular, aprovechando así el crecimiento muy lento que tenía el tumor. Al cabo de 5 semanas de iniciar la distracción se objetivó una gran masa tumoral de nueva aparición al nivel del suelo de la boca anterior, que posteriormente se confirmó que tenía el mismo diagnóstico histopatológico que el tumor inicial. Resultados. Debido a la inesperada ocurrencia de la complicación presentada tuvimos que abandonar la distracción, y decidimos realizar una resección de espesor total del tercio facial inferior y la reconstrucción del defecto con un injerto libre vascularizado de peroné y un colgajo miocutáneo pectoral. Conclusión. La distracción osteogénica puede complicar el curso de un proceso neoplásico local y su uso debe ser valorado como posible contraindicación en pacientes con procesos tumorales activos (AU)


Purpose. to report an unusual case of aggressive tumoral growth related to the use of mandibular distraction. The clinical situation presented suggests that the biochemical factors released during the osseous distraction can interfere with the development of the active malignant tumors, triggering a rapid progression. Material and methods. We present the case of a patient who had a history of recurrent sclerosing basal cell carcinoma in the left chin area. Despite of the multiples attempts to completely remove the tumor and the close follow- up conducted, 18 years from the initial diagnosis the biopsies taken showed tumoral infiltration of the mandibular bone. In order to take advantage of the slow rate of the tumoral growth, we decided to carry out a bilateral mandibular distraction before performing the mandibular resection and reduce in this manner the amount of the bone necessary for the reconstruction. Five weeks after the onset of the bone distraction a newly emerging tumoral mass could be observed in the anterior floor of the mouth, which was confirmed to have the same histological diagnose as the initial tumor. Results. Due to the unexpected complication we had to abandon the distraction and decided to perform a full-thickness resection of the inferior third of the face and the reconstruction of the defect using a free vascularized fibular graft and a pectoralis major myocutaneous flap. Conclusion. Distraction osteogenesis can complicate the course of a local neoplastic process and its use should be valued as a potential contraindication in patients with active tumors (AU)

ABSTRACT

Objetivos. Evaluar el protocolo quirúrgico y discutir los posibles factores predisponentes de la periimplantitis apical. Material y método. En el presente trabajo, se planteó un estudio descriptivo retrospectivo analizando una serie de 11 casos clínicos de periimplantitis apical diagnosticados y tratados en el ámbito del Hospital de La Princesa (Madrid) y la Clínica Universidad de Navarra (Pamplona) entre 2002 y 2013. Los pacientes sintomáticos fueron tratados mediante legrado de la zona con o sin relleno. Resultados. Se analizaron un número total de 11 casos de periimplantitis apical (4 asintomáticos y 7 con síntomas). La clínica observada fue parecida a la enfermedad dentaria periapical y el tiempo transcurrido hasta el diagnóstico fue variable, inferior a los 3 años. Se observó resolución completa del problema en 6 de los 7 casos tratados con legrado de la zona periapical del implante. En el caso restante se procedió a la explantación del implante afecto. En los casos asintomáticos no se realizó ningún tipo de tratamiento quirúrgico, presentando una tendencia autolimitada. Conclusión. La periimplantitis apical es una enfermedad que puede complicar el tratamiento implantológico. La cirugía conservadora ha tenido resultados satisfactorios en los casos sintomáticos (AU)


Objectives. The purpose of this study was to evaluate the surgical protocol and discuss possible predisposing factors of apical peri-implantitis. Material and methods. A retrospective study was performed by analyzing a series of cases involving 11 patients, all of whom where diagnosed with, and treated for, apical peri-implantitis at La Princesa Hospital in Madrid and at Navarre University Clinic in Pamplona, Spain, between 2002 and 2013. Symptomatic patients were treated with curettage of the area, which was, in some cases, combined with bone regeneration techniques. Results. A total of 11 cases of apical periimplantitis were included (4 asymptomatic and 7 symptomatic). The symptoms observed were similar to dental periapical pathology, and the period of time elapsed until the patients were diagnosed with API was variable, but was less than 3 years. Complete resolution of the pathology was observed in 6 of the 7 patients treated with curettage of the periapical implant area. In the remaining case the affected implant was removed. No surgical treatment was used in asymptomatic cases, as they were self-limiting. Conclusion. Apical periimplantitis is a condition which may complicate the dental implant treatment. Conservative surgical treatment has shown satisfactory results in symptomatic patients (AU)

ABSTRACT

El presente artículo estudia la posibilidad de restringir la inclusión de los pacientes sometidos a intervenciones de cirugía ortognática en el protocolo de autotransfusión con predepósitos utilizando parámetros preoperatorios (la mayor edad, el sexo femenino, el tipo de cirugía más invasiva) y valora la necesidad cuantitativa de sangre (número de bolsas utilizadas). Material y método. Realizamos un estudio descriptivo retrospectivo que comprende 91 de intervenciones de cirugía ortognática realizadas entre el junio del 2007 y el diciembre de 2010 en el Hospital de La Princesa - Madrid que describe en términos analíticos el manejo de las pérdidas sanguíneas y busca una relación entre varios parámetros como: edad, tipo de cirugía, tiempo de cirugía, los valores de hemoglobina pre-, intra- y postoperatoria, el número de bolsas de sangre recibidas y el sexo. Resultados. No se han encontrado correlaciones estadísticamente significativas entre la necesidad de transfusión y: la mayor edad (p = 0,23), el sexo femenino (p = 0,11), el mayor tiempo de cirugía (p = 0,93), el tipo de cirugía más invasiva (p = 0,284) con lo cual estos parámetros no suponen un mayor riesgo de sangrado ni de ser transfundido. Conclusión. En nuestro grupo de estudio los parámetros enumerados no sirven en el preoperatorio para delimitar un grupo de pacientes para los cuales la inclusión en el protocolo de autotransfusión sería beneficiosa. Los resultados indican la posibilidad de reducir la cantidad de sangre ahorrada por protocolo e indican una probable sobreindicación del procedimiento(AU)


Objectives: The present article studies the possibility of restricting the inclusion of patients undergoing orthognathic surgical procedures in the autologous transfusion protocol with pre-deposited blood using preoperative parameters (age, female gender, more invasive type of surgery), as well as assessing the amount of blood required (number of bags used). Material and Methods: We conducted a retrospective study comprising 91 orthognathic surgery interventions performed between June 2007 and December 2010 at the La Princesa Hospital - Madrid, which describes, in analytical terms, the management of blood loss and looks for a relationship between various parameters such as age, type of surgery, duration of surgery, pre-, intra- and postoperative haemoglobin values, number of blood bags used and gender. Results: No statistically significant correlationswere found between the need for transfusion and: older age (p = .23), female gender (p = .11), increased duration of surgery (p = .93), the more invasive type of surgery (p = .284), thus these parameters do not pose an increased risk of bleeding or of being transfused. Conclusion: In our study group, the parameters listed in the preoperative evaluation do not serve the purpose of restricting a group of patients for whom the inclusion in the autotransfusion protocolwould be beneficial. The results showthe possibility of reducing the amount of blood saved per protocol and indicate a probable over-recomendation of the procedure(AU)
