ABSTRACT

INTRODUCCIÓN: Las fracturas patológicas de mandíbula representan menos del 2 % del total de las fracturas de mandíbula y frecuentemente afectan a pacientes adultos mayores. En pacientes mayores de 65 años estas fracturas podrían presentar características diferentes a las de la población general por su asociación con múltiples comorbilidades. MATERIALES Y MÉTODOS: Presentamos un estudio descriptivo retrospectivo de una serie de 15 casos de fracturas patológicas de mandíbula. Solo se incluyeron pacientes mayores de 65 años y se recolectaron las siguientes variables: sexo, edad, etiología, localización, tratamiento y complicaciones postoperatorias. Además se llevó a cabo una revisión de la literatura en PubMed acerca de fracturas patológicas de mandíbula. RESULTADOS: La edad promedio fue de 72 años (rango: 65-85) y el 67 % (n = 10) de los casos fueron pacientes de sexo femenino. La etiología más frecuente fue la osteonecrosis asociada a medicamentos (ONAM) (40 %). La tasa de complicaciones postoperatorias fue del 53 % (8/15). En la revisión de la bibliografía se identificaron 24 artículos acerca de fracturas patológicas de mandíbula. Solo tres publicaciones incluyen más de 10 PACIENTES: Ninguna incluye pacientes adultos mayores exclusivamente. CONCLUSIONES: En nuestra serie encontramos que la etiología más frecuente fue la ONAM. Estos pacientes pueden ser tratados de forma exitosa siguiendo los algoritmos propuestos para la población general, aunque la tasa de complicaciones es elevada (53 %)


INTRODUCTION: Pathological fractures of the mandible account for fewer than 2 % of all mandibular fractures and often affect elderly patients. In patients over 65 years of age, these fractures may present features that are different from those observed in the general population because of their association with multiple comorbidities. MATERIALS AND METHODS: In this paper, we present a retrospective study of a series of 15 cases of pathological fractures of the mandible. Only patients over 65 years old were included, and the following variables were collected: sex, age, etiology, localization, treatment and postoperative complications. Additionally, we conducted a literature review in PubMed on pathological fractures of the mandible. RESULTS: The mean age was 72 years (range 65-85) and 67 % (n=10) were female patients. The most common etiology was medicine-related osteonecrosis of the jaws (40 %). The postoperative complication rate was 53 % (8/15). We identified 24 articles assessing pathological fractures of the mandible in our review of the literature. Only three articles included more than 10 patiens. None of them related exclusively to elderly patients. CONCLUSIONS: In our series, the most frequently encountered etiology was medicine-related osteonecrosis of the jaws. These patients can be treated successfully following the same algorithms used in the general population, albeit the complication rate is high (53 %)

ABSTRACT

Hemophilia is an inherited coagulation disorder characterized by deficiency of the coagulation factor VIII or IX. When the management of hemostasis is inadequate, these patients are at high risk of experiencing intra and postoperative bleedings after tooth extractions. Coagulation factor replacement therapy allows performing most surgical procedures safely, although the factor levels and length of treatment have not been clearly determined. In this study, we present our experience in a retrospective series of 112 ambulatory tooth extractions under local anesthesia in 23 patients with hemophilia using a coagulation factor replacement therapy in combination with tranexamic acid. The results obtained with this protocol were satisfactory and only one episode of mild postoperative bleeding occurred after seven days in a patient who did not have good treatment compliance. Key words:Hemophilia, factor replacement therapy, tooth extractions, postoperative complications.

ABSTRACT

La osteonecrosis asociada a medicamentos (ONAM) es un efecto adverso poco frecuente pero potencialmente serio que afecta a pacientes que reciben o recibieron tratamiento con drogas antirresortivas o antiangiogénicas. A partir de una revisión narrativa de la literatura, el presente artículo aporta conceptos básicos e información actualizada acerca de incidencia, factores de riesgo y prevención de ONAM desde la perspectiva de la Práctica Basada en la Evidencia. Además pone en conocimiento a la comunidad profesional de la Facultad de Odontología de la Universidad de Buenos Aires acerca de las actividades de investigación clínica llevadas a cabo en este área en la Cátedra de Cirugía y Traumatología Buco-Máxilo-Facial I de nuestra casa de estudios (AU)


Medicine related osteonecrosis of the jaws (MRONJ) is a rare but potentially serious side effect experienced by patients receiving treatment with antiresorptive or antiangiogenic drugs. Through a narrative review of the literature, this paper provides basic concepts and updated data about incidence, risk factors and prevention of MRONJ from the Evidence Based Practice perspective. It also informs the professional community of the School of Dentistry of the University of Buenos Aires about the clinical research activities carried out in this area in the Oral and Maxillofacial Surgery I Department (AU)
