ABSTRACT

El macizo facial es una región anatómica compleja que alberga órganos sensoriales. El desarrollo de una enfermedad oncológica, así como su tratamiento, causan defectos funcionales y estéticos con un alto costo físico y psíquico para el paciente y su entorno. Es por ello que la reconstrucción representa un reto. Las diferentes posibilidades incluyen prótesis obturatríces, colgajos libres, pediculados o microvascularizados. En este artículo se describirá el colgajo de músculo temporal y se desarrolla un caso clínico de cirugía oncológica maxilar reconstruido mediante éste en un paciente que presenta una lesión exofítica en cuadrante superior derecho, que se extiende sobre el flanco vestibular, reborde alveolar y zona palatina, desde zona de premolares hasta la zona del segundo molar inclusive, impidiéndole usar la prótesis dental. Esta cirugía es una técnica económica, que requiere menor tiempo quirúrgico que otras técnicas, asociándose a poco porcentaje de fracaso y pocas complicaciones post operatorias.


The facial mass is a complex anatomical region that houses sensory organs. The development of an oncologic disease, as well as its treatment, causes functional and esthetic defects with a high physical and psychological cost for the patient and his environment. This is why reconstruction represents a challenge. The different possibilities include obturator-root prostheses, free, pedicled or microvascularized flaps. In this article the temporal muscle flap will be described and a clinical case of maxillary oncologic surgery reconstructed by means of it is developed in a patient who presents an exophytic lesion in the right upper quadrant, which extends over the vestibular flank, alveolar ridge and palatal area, from the premolar area up to and including the second molar area, preventing him from using the dental prosthesis. This surgery is an economical technique that requires less surgical time than other techniques, and is ass

ABSTRACT

Ameloblastic fibro-odontoma (AFO) is a mixed odontogenic tumor, which has an epithelial and mesenchymal component. It can be observed in imaging tests as a radiomixed lesion, with some authors claiming it represents only the predecessor of an odontoma. Epidemiologically, it appears between the second and third decade of life, predominantly in males and with a predilection for the posterior area of the mandible. This lesion presents a good prognosis and it responds well to enucleation by curettage with a low rate of recurrence. In the present article, two cases of ameloblastic fibro-odontoma in an unusual region of the maxilla are presented.


El Fibro-odontoma ameloblástico (FOA), es una lesión tumoral mixta de origen odontogénico, el cual tiene un componente epitelial y mesenquimático. En su imagenología se observa como una lesión radiomixta, debido a que algunos autores afirman que este no es más que el predecesor de un odontoma. Epidemiológicamente, se presenta entre la segunda y tercera década de la vida, preferencia por sexo masculino y predilección por el área posterior de la mandíbula. Es una lesión de buen pronóstico que responde bien a la enucleación por curetaje con baja tasa de recidiva. En el presente artículo, se presentan dos casos de fibro-odontoma ameloblástico en una región inusual de los maxilares.

ABSTRACT

Introdução: o odontoma é um tipo de tumor do epitélio odontogênico com ectomesênquima, podendo estar relacionado à presença de dentes não irrompidos. O tratamento consiste em excisão cirúrgica da lesão. Nor-malmente, dentes impactados são assintomáticos, sendo descobertos em radiografias de rotina. A impactação é causada por fatores sistêmicos ou etiológicos locais. Objetivo: reportar um caso clínico de uma criança com impactação dentária de um incisivo central superior esquerdo associado a um odontoma, enfatizando e discutindo a técnica cirúrgica e o planejamento realizado. Relato de caso: paciente de 13 anos de idade, do gênero feminino, com a não erupção do incisivo central superior esquerdo, ao exame clínico, apresentou ausência clínica do dente 21, persistência do dente 61 e um discreto aumento de volume entre os elementos 61 e 22. Foi solicitada uma tomografia computadorizada de feixe cônico (cone beam) da região, na qual se diagnosticou a presença de uma massa radiopaca envolta por um halo radiolúcido sugestivo de odontoma composto, alterando a posição e impedindo a erupção do dente 21, que se encontrava em posição transal-veolar. O plano de tratamento proposto foi remoção cirúrgica do odontoma e tracionamento do dente não irrompido. Conclusão: a remoção cirúrgica de patologias associadas e as manobras referentes aos dentes envolvidos devem ser realizadas no momento mais oportuno e com adequado planejamento, evitando lesões a estruturas nobres e permitindo, assim, um processo de reparo adequado e uma completa restauração da saúde bucal do paciente.

Introduction: Odontoma is a type of tumor of the odontogenic epithelium with ectomesenchyme and it may be related to the presence of unerupted teeth. The treatment consists of surgical excision of the lesion. Usually, unerupted teeth are asymptomatic and discovered in routine radiographs. Impaction is caused by local systemic or etiological factors. Objective: The present study aims to report a clinical case of a child with an impacted upper central incisor associated with an odontoma, highlighting and discussing the surgical technique and treatment planning. Case report: A 13-year-old female patient without eruption of the left upper central incisor. After clinical examination, the absence of tooth 21, persistence of tooth 61, and a discrete volume increase between elements 61 and 22 were observed. A cone beam computed tomography of the region was requested, which diagnosed the presence of a radiopaque mass involved by a radiolucent halo suggestive of compound odontoma. This condition changed the position and prevented the eruption of tooth 21, which was found in a transalveolar position. The treatment plan proposed was the surgical removal of the odontoma and orthodontic traction of the unerupted tooth. Conclusion: The surgical removal of associated pathologies and maneuvers related to the teeth involved should be performed in a timely manner, with adequate planning, preventing lesions in noble structures, thus allowing an adequate repair process and a complete restoration of the oral health of the patient.

ABSTRACT

There are various types of obturator fabrication achievable by prosthodontist. Maxillectomy, which is a term used by head and neck surgeons and prosthodontists to describe the partial or total removal of the maxilla in patients suffering from benign or malignant neoplasms is a defect for which to provide an effective obturator is a difficult task for the maxillofacial prosthodontist. Multidisciplinary treatment planning is essential to achieve adequate retention and function for the prosthesis. Speech is often unintelligible as a result of the marked defects in articulation and nasal resonance. This paper describes how to achieve the goal for esthetics and phonetics and also describes the fabrication of a hollow obturator by two piece method, which is simple and maybe used as definitive obturator for maximum comfort of the patient.

ABSTRACT

Ameloblastic fibroma is a relatively rare benign odontogenic tumor in which both the epithelial and ectomesenchymal components are neoplastic. An 8-year-old Caucasian boy was referred to the dentist for evaluation of failed eruption of the maxillary left first molar. The panoramic radiograph showed a well-circumscribed unilocular radiolucency involving an unerupted maxillary left first permanent molar. The lesion was enucleated and the material was sent for histopathologic examination. Microscopically, it was composed by cords and islands of odontogenic epithelium in a myxoid cell-rich stroma that closely resemble the dental papilla with histopathological diagnosis of ameloblastic fibroma. After 24 months of follow-up no recurrence was observed and the maxillary left first molar erupted spontaneously through the buccal mucosa and was aligned with a fixed orthodontic appliance. This case emphasized the importance of careful differential diagnosis of intraosseous oral lesions and reported a rarity of the lesion and its atypical location.


Fibroma ameloblástico é um tumor odontogênico benigno relativamente raro, em que ambos os componentes epiteliais e ectomesenquimais são neoplásicos. Menino de oito anos de idade, branco, foi encaminhado ao dentista para avaliar a falha na erupção do primeiro molar maxilar do lado esquerdo. A radiografia panorâmica revelou imagem radiolúcida, unilocular, bem circunscrita, envolvendo o primeiro molar permanente maxilar esquerdo incluso. A lesão foi enucleada e o material encaminhado para avaliação histopatológica. Microscopicamente, era composta de ilhas e cordões de epitélio odontogênico num estroma mixóide rico em células, que se assemelhava à papila dentária, com diagnóstico histopatológico de fibroma amelobástico. Após 24 meses de acompanhamento, nenhuma recorrência foi observada e o primeiro molar permanente maxilar irrompeu espontaneamente através da mucosa bucal e foi alinhado com aparelho ortodôntico fixo. Esse caso enfatiza a importância do cuidadoso diagnóstico diferencial das lesões orais intra-ósseas e relato de lesão rara e sua localização atípica.

ABSTRACT

Florid cemento-osseous dysplasia (FCOD) has been described as a condition that characteristically affects the jaws of middle-aged black women. It usually exhibits as multiple radiopaque cemetum-like masses distributed throughout the jaws. Radiographically, FCOD appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. Computed tomography, because of its ability to give axial, sagittal, and frontal views, is useful in the evaluation of these lesions. This paper presents the case of a patient who was diagnosed with FCOD on the basis of clinical and radiographic findings.


A displasia cemento-óssea florida (DCOF) tem sido descrita como uma condição que afeta tipicamente os maxilares de mulheres negras de meia idade, geralmente exibindo massas radiopacas semelhantes ao cemento, distribuídas nos ossos maxilares. Radiograficamente, a DCOF apresenta-se como densas masas lobuladas, frequentemente distribuídas simetricamente em diversas regiões dos maxilares. A tomografia computadorizada, que oferece vistas axial, sagital e frontal, é útil na avaliação dessas lesões. Este artigo apresenta o caso de uma paciente em que a DCOF foi diagnoasticada com base nos achados clínicos e radiográficos.

ABSTRACT

Odontomas are the most common type of odontogenic tumors and generally they are asymptomatic. Frequently it may interfere with the eruption of the teeth. This is a case report of a compound composite odontoma in a 9 year old girl, which results in failure of eruption of the permanent upper right central incisor while the contralateral tooth had erupted. A calcified mass was seen in the radiograph and was provisionally diagnosed as odontoma following which the odontoma was enucleated. Routine follow up was done for more than a year and no recurrence was seen. This case report indicates that early diagnosis and management ensures better prognosis.

ABSTRACT

Compound composite odontoma, is a tumor formed by the overgrowth of transitory or complete dental tissue, made up of one or more rudimentary teeth. Although odontomes are considered to be quite common of odontogenic tumors, these rarely occur solely in primary dentition. This paper is a report of case of a compound composite odontoma, five year old child who presented to the Department of Pedodontics and preventive Dentistry, College of Dental Surgery, Manipal.

ABSTRACT

Se describen 36 pacientes con osteosarcoma a nivel maxilar, diagnosticados en el INC durante treinta y tres años, lo que representa para nuestra institución, 1,09 nuevos casos por año. La edad de presentación fue en promedio de 32 años. En la mayoría de los casos no se hallaron factores predisponentes para el desarrollo de la neoplasia y aparentemente se iniciaron de novo. Los síntomas fueron masa y dolor. La imágen radiológica fue poco específica, la presencia de reacción perióstica, calsificaciones y ensanchamiento del espacio de la membrana periodontal aunque son hallazgos muy sugestivos de osteosarcoma, se evidenciaron únicamente en el 36 por ciento de los casos. En el 63.9 por ciento de los pacientes los tumores eran voluminosos, con compromiso de varias zonas anatómicas al momento del diagnóstico, intramedulares y de alto grado histológico de malignidad; no observamos osteosarcomas parostales. Como hallazgo interesante, se diagnosticaron seis casos de tumores múltiples de orígen óseo y no óseo asociados al tumor maxilar
