ABSTRACT

Objetivo: El objetivo de la I Conferencia Española de Consenso sobre el Injerto Óseo Sinusal era intentar llegar a puntos de acuerdo sobre las principales controversias de esta técnica, aplicada de forma muy variada y con el empleo de materiales muy diversos, y conseguir plasmar los mismos en un documento resumen consensuado por todos los autores. Material y método: Durante los días 17 y 18 de octubre de 2008 se celebró en Oviedo la citada conferencia, auspiciada por la Sociedad Española de Cirugía Oral y Maxilofacial. En ella se dieron cita un total de 50 ponentes de reconocido prestigio nacional e internacional que repasaron en 6 mesas de trabajo las principales controversias sobre los injertos óseos sinusales. Tras las conferencias de los ponentes, los moderadores establecían las principales conclusiones de cada mesa y se abría un turno de debate donde participaban todos los asistentes. Resultado: Este documento y sus conclusiones emanan de las presentaciones realizadas por los ponentes y de las deliberaciones y acuerdos de cada mesa de trabajo. Ambos han sido aprobados tras varias correcciones por todos los autores antes de ser enviados para su publicación. Además, han obtenido el reconocimiento científico oficial de la Sociedad Española de Cirugía Oral y Maxilofacial y deben servir como base para futuros estudios y reuniones científicas. Conclusiones: El objetivo fundamental cuando se realiza un injerto óseo sinusal es la formación de hueso vital en el seno maxilar, para conseguir la supervivencia a largo plazo de los implantes tras su carga protésica. Para ello, la técnica y la secuencia de tratamiento deben orientarse a conseguir resultados predecibles y estables en el tiempo, aunque esto suponga un mayor tiempo de espera hasta la colocación de la prótesis. La estabilidad inicial del implante es el factor clave para la osteointegración y debe ser el principal criterio para indicar implantes simultáneos o diferidos en el seno maxilar(AU)


Objective: The objectives of the first Spanish Consensus Conference on Sinus Bone Graft were trying to reach agreements points on the major controversies of this technique, and translate them in a summary document. Material and method: During the 17th and 18th of October of 2008 took place in Oviedo (Spain) the Conference, sponsored by the Spanish Society of Oral and Maxillofacial Surgery. There, 50 national and international speakers reviewed in 6 workshops the major controversies of sinus bone grafts. Following the conferences, the moderators proposed the main conclusions of each workshop and opened a round of discussion where all attendees participated. Results: This document and its conclusions emanate from the presentations made by the speakers and the discussions and agreements of each workshop. Both have been approved after several corrections by all authors before being submitted for publication. They have also obtained the official scientific recognition of the Spanish Society of Oral and Maxillofacial Surgery and should serve as a basis for future scientific studies and meetings. Conclusions: The main objective when we perform a sinus bone graft is vital bone formation in the maxillary sinus, to achieve long-term survival of the implants after prosthetic loading. To do this, the technique and sequence of treatment should aim to achieve predictable and stable results over time, although this involves a longer waiting time. The initial implant stability is the key factor for osseointegration and should be the main criterion to indicate simultaneous or delayed implants in the maxillary sinus(AU)

ABSTRACT

OBJECTIVE: Schwannomas are slowly growing tumours derived from Schwann cells. We present a clinical case of schwannoma in the mandibular angle. METHOD: Case report and a review of the world literature concerning intraosseous schwannoma of the maxillofacial region. RESULTS: Schwannomas or neurilemmomas are slow-growing, benign neoplasms derived from Schwann cells. Intraoral lesions are unusual and intraosseous schwannomas are even rarer, representing less than 1 per cent of benign primary tumours of the bones. We present a clinical case of schwannoma in the mandibular angle mimicking a keratocystic odontogenic tumour, with a complicated posterior evolution. CONCLUSION: Clinically, neurilemmomas are slow-growing tumours which may be present for years before becoming symptomatic. Radiographically, the image may be suggestive of a benign process such as an odontogenic keratocyst. Histological analysis of the specimens obtained is extremely important in order to establish the final diagnosis.

ABSTRACT

Introducción. Los osteomas son tumores óseos benignos de crecimiento lento, localizados principalmente en la región cráneo-máxilofacial. El tratamiento de las lesiones silentes suscita controversia pues no seha evidenciado su poder de malignización. Material y Método. Se presentan 3 casos poco habituales de osteomas craneofaciales localizados en los huesos frontal, etmoides y mandibula. Discusión. Se realiza una revisión de la literatura realizando una comparativa razonada de la actitud tomada en los casos presentados, discutiendo las ventajas e inconvenientes de lostratamientos realizados. Conclusiones. Se debe realizar una valoración individualizada de cada caso para decidir su manejo, teniendo en cuenta el riesgo derivado de la intervención así como el riesgo derivado de la conductaexpectante. El tipo de cirugía en estos tumores vendrá determinada por su tamaño y localización


Introduction. Osteomas are benign, slow-growing tumorsthat are located principally in the cranio-maxillo-facial region. Treatment of these silent lesions has resulted in controversy, as their potential for becoming malignant has not been demonstrated.Material and Methods. Three somewhat uncommon cases of craniofacial osteomas located in frontal, ethmoid and mandible bones are presented. Discussion. A revision of the literature is carried out, and a reasoned comparison is made of the attitude taken in the cases presented. The advantages and disadvantages of the treatmentcarried out are discussed. Conclusions. Each case should be assessed individually in order to decide how it should be dealt with,taking into account the risk derived from the surgery as well as the risk derived from a wait and watch strategy. The type of surgery for these tumors is determined by their size and location
