RESUMO

BACKGROUND: The authors present a technique for selected cases of CBCL. The primary repair of the CBCL with a severely protruding premaxilla in one stage surgery is very difficult, essentially because a good muscular apposition is difficult, forcing synchronously to do a premaxillary setback to facilitate subsequent bilateral lip repair and, thus, achieving satisfactory results. We achieve this by a reductive ostectomy on the vomero-premaxillary suture. MATERIAL AND METHODS: 4 patients with CBCL and severely protruding premaxilla underwent premaxillary setback by vomerine ostectomy at the same time of lip repair in the past 24 months. The extent of premaxillary setback varied between 9 and 16 mm. The required amount of bone was removed anterior to the vomero-premaxillary suture. The authors did an additional simultaneous gingivoperiosteoplasty in all patients, achieving an enough stability of the premaxilla in its new position, to be able to close the alveolar gap bilaterally. The authors have examined the position of premaxilla and dental arch between 6 and 24 months. We did not do the primary nose correction, because this increased the risk of impairment of the already compromised vascularity of the philtrum and premaxilla. RESULTS: The follow-up period ranged between 6 and 24 months. None of the patients had any major complication. During follow-up, the premaxilla was minimally mobile. We achieved a good lip repair in all cases: adequate muscle repair, symmetry of the lip, prolabium and Cupid's bow, as well as good scars. CONCLUSIONS: To our knowledge, there are few reports of one stage surgery with vomerine ostectomy to repair CBCL with severely protruding premaxilla. Doing this vomerine ostectomy, we don't know how it will affect the subsequent growth of the premaxila and restrict the natural maxillary growth. Applying this alternative treatment for children with CBCL and protruded premaxilla without any preoperative orthopedic, we can successfully perform, in a single-stage surgery, a good primary lip repair at our center. Further confirmations of this surgery with follow up and anthropometric studies of these patients during childhood and adolescence are required

RESUMO

In the present study we report and discuss a case of odontogenic myxoma in a 13-month-old patient. Only two other reports have been published in the literature describing the occurrence of this type of tumor at an earlier age. Odontogenic myxoma is a benign mesenchymal neoplasm of the maxilla more common between the third and fourth decades of life. The case here reported is exceptional as it presents in an infant and, although some cases have been reported in the literature, this type of tumor is rare in early childhood. The most common locations include the ascending ramus and the angle of the jaw, although these tumors may also affect the upper maxilla, in which case they may involve the maxillary sinus. According to the review of the literature, these tumors show a recurrence rate of about 25%. Consequently, after the intraoperative clinical examination of the lesion and the assessment of the initial suspected diagnosis by means of intraoperative biopsy under general anesthesia, we carried out the resection of the tumor with wide margins at some points of the tumor location.

RESUMO

En este artículo presentamos y discutimos el caso de un mixomaodontogénico en un paciente de 13 meses. En la literatura existen publicados sólo dos casos en los que se describe la aparición de este tumor a una edad más temprana. El mixoma odontogénico es un tumor benigno de los maxilares de origen mesenquimal, que se presenta con mayor frecuencia entre la tercera y la cuarta décadas de la vida. Nuestro caso se presenta de manera excepcional, en un lactante, ya que, aunque aparecen casos descritos en la literatura, es un tumor poco frecuente en la primera infancia. Las localizaciones más frecuentes son la rama ascendente y el ángulo de la mandíbula, aunque también lo encontramos a nivel del maxilar superior, en cuyo caso puede invadir el seno maxilar. Estos tumores, en función de la literatura revisada, presentan una tasade recidiva cercana al 25%, por lo que, tras el aspecto clínico intraoperatorio de la lesión y verificarse el diagnóstico de sospecha inicial mediante la biopsia intraoperatoria tomada bajo anestesia general, se decidió realizar una extirpación con márgenes de seguridad en algunas zonas de la localización tumoral (AU)

RESUMO

Primary intraosseous hemangioma, though rarely affect the bones of the orbit, should be considered in the differential diagnosis when a patient presents an enlarging mass fixed to the bone in the orbit or signs of progressive painless proptosis. Assessing the exact site and extent of the hemangioma by means of a CT scan and MRI and establishing the vascular origin of the lesion, is critical in the therapeutical planning, since an inadequate management may result in a severe hemorrhage. Progressive proptosis and contour deformity require surgical treatment. Two cases of patients with primary intraosseus hemangioma of the supra-lateral orbital rim are reported. A bony healthy margin excision was performed, followed by immediate reconstruction of the orbit with calvarial bone grafts fixed with resorbable plates. After three-year follow-up there have not been evidence of local recurrence, and the functional and aesthetic results obtained have been very satisfactory.

RESUMO

El hemangioma intraóseo primario, aunque rara vez afecta a los huesos de la órbita, se debe tener encuenta en el diagnóstico diferencial en aquellos pacientes que presenten una masa fija en la órbita o signos de proptosis progresiva no dolorosa. Para el planteamiento terapéutico es crítico valorar la localización exacta y la extensión de la lesión mediante TC y RNM, y establecer si tiene un origen vascular, pues un manejo inadecuado puede dar lugar a una hemorragia severa. El tratamiento quirúrgico se indica ante una proptosis progresiva o una deformidad estética. Se presentan dos casos de pacientes con hemangiomas primarios intraóseos del reborde supralateral de la órbita. Se realizó una extirpación con un margen óseo sano y se reconstruyó la órbita de forma inmediata mediante injertos de calota fijados con placas reabsorbibles. En el seguimiento a 3años no ha habido evidencia de recurrencia local, y los resultados funcionales y estéticos obtenidos han sido muy satisfactorios

RESUMO

Introducción. Las heridas por armas de fuego son poco frecuentes en nuestro medio, de ahí que la experiencia en el manejo de las mismas sea limitada. En este artículo mostramos la experiencia de nuestro Servicio en el tratamiento de estas lesiones y realizamos una revisión del tema para intentar protocolizar la actuación inicial ante este tipo de pacientes. Material yMétodo. Presentamos seis casos tratados en nuestro Servicio durante el año 2002. Estudiamos las características demográficas, etiología, patrón de lesiones y tratamiento recibido. Resultados. Cinco hombres y una mujer presentaron heridas por arma de fuego durante este período, con una edad media de 38 años (Rango 13-74). La etiología más frecuente fue la agresión, seguido del intento de autolisis. Sólo un paciente requirió estabilización urgente de vía aérea mediante traqueotomía. No existieron complicaciones postoperatorias y sólo un enfermo requirió intervenciones secundarias por secuelas.Discusión. El aspecto más controvertido en el tratamiento de estas lesiones es el manejo quirúrgico de pacientes con lesiones extensas de la cara que involucranpartes blandas y hueso, ya que pueden tratarse con técnicas reconstructivas complejas en el primer acto operatorio o, por el contrario, esta reconstrucciónse puede realizar de forma diferida tras una primera fase de tratamiento quirúrgico de desbridamiento, estabilización de fracturas y cierre de partes blandas con técnicas simples. Pensamos que la elección del tipo de tratamiento debe ser individualizada en cada caso, aunque solemos optar por una reconstrucción diferida de los defectos tan pronto como sea posible


Introduction. The firearm injuries are not very commonin our country, and the experience in its management is limited. In this review we show the experience of our Service in this wounds and review the literature to systematize the initial management of the firearm injuries in maxillofacial region. Material and Method. We present six patients treated in our Service in 2002. We study the demographics characteristic, aetiology, lesions patterns and treatment. Results. Five male and a female were treated of firearm lesions during this period, with a mean age of 38 years (range 13-74). Most frequent aetiology was the aggression. Only one patient required emergency airway control with tracheotomy. No complications were noted after primary surgical treatment and only one patient needed secondary surgical intervention. Discussion. There are controversy in definitive surgical treatment in patients with high-energy lesions in maxillofacial region , because the literaturedescribe two forms of management. The first way is theprimary reconstruction with microvascular techniques, or secondary reconstruction after desbridement, stabilization of existing bone and primary closure of soft tissue. We think that the choice of treatmentmust be individualized, and we choose the secondary reconstruction as early as possible after primary stabilization of wounds

RESUMO

OBJECTIVES: The more successfully surgical treatment for the treatment of chronic frontal sinusitis complicated with chronic osteomielitis, is the cleaning and curettage of the sinus with obliteration of the sinus cavity and nasofrontal duct. Several autologous and alloplastics materials are used for this obliteration. MATERIAL AND METHODS: We report the case of a patient previously operated on because of frontal sinus plasmocytoma who developed frontal sinusitis with chronic osteomielitis and cutaneous suppuration. He received surgical treatment with frontal sinus curettage and obliteration with tibial bone graft and platelet-rich plasma (PRP). Symptoms disappeared and there were no complications or recurrence. CONCLUSIONS: Obliteration of the frontal sinus with tibial bone graft and PRP after sinus cleaning and curettage can be a good alternative in the treatment of chronic frontal sinus osteomielitis.

RESUMO

Introducción. La cirugía reconstructiva tras la exéresis de tumores malignos que afectan a la lengua y al suelo de boca, continúa siendo uno de los grandes retos de la cirugía oral y maxilofacial. La mayor recuperacióndel habla y de la deglución, van a ser los objetivos finales de toda la reconstrucción de la cavidad oral. Presentamos un nuevo diseño del colgajo libre radial para la cirugía reconstructiva del carcinoma lengua y suelo de boca. Material y método. Nuestra serie consta de tres pacientes diagnosticados de carcinoma epidermoide de lengua y suelo de boca. Tras la cirugía oncológica ablativa, se reconstruyó el defecto oral con un colgajo libre radial de doble paleta cutánea con zona intermedia desepidermizada microvascularizado. Resultados. La movilidad de la lengua de nuestros pacientes fue suficiente y adecuada, consiguiéndose una buena calidad de vida. No hubo pérdida de la comida u otros fluidos a través del tracto respiratorio. Conclusiones. Con el colgajo radial de doble paleta cutánea microvascu-larizado, se consigue una buena recuperación funcional tanto en el habla como en la deglución en los pacientes, por lo que creemos que debería estandarizarse su uso en la cirugía recons-tructiva oral tras la exéresisde tumores malignos de lengua y suelo de boca (AU)

RESUMO

Una de las complicaciones más serias del uso de la radioterapia en el tratamiento del carcinoma epidermoide de la cavidad oral, es la osteorradionecrosis. En este trabajo, presentamos cuatro pacientes afectos de osteorradionecrosis masiva de la mandíbula que habían fracasado inicialmente con medidas conservadoras y que fueron tratados con resección radical y reconstrucción primaria con un colgajo libre osteoseptocutáneo de peroné. El defecto mandibular tras la resección ósea midió una media de 10 cm e incluyó mucosa intraoral, piel o ambos. En dos casos de reconstrucción, se empleó el colgajo libre de peroné con doble paleta para reconstruir defectos extensos intra y extraorales. Se realizaron osteotomías en el peroné vascularizado en todos los casos para recrear el contorno mandibular. Todos los colgajos sobrevivieron completamente. Tres pacientes curaron primariamente con buenos resultados estéticos y funcionales. Una paciente falleció en el primer mes tras la operación por una pancreatitis aguda y fallo renal. En un paciente se han insertado implantes osteointegrados. En nuestra experiencia, el colgajo libre osteoseptocutáneo de peroné puede ser una opción ideal para la reconstrucción en un solo tiempo de defectos complejos mandibulares compuestos en pacientes afectos de osteorradionecrosis masiva.
