RESUMO Objetivo: Traçar o perfil dos pacientes internados com trauma de face em um hospital localizado em região metropolitana do Nordeste do Brasil. Métodos: Tratou-se de estudo transversal e exploratório. Um total de 244 casos atendeu aos critérios de elegibilidade, sendo incluídos na amostra. As variáveis estudadas incluíram características sociodemográficas das vítimas, etiologia, tipos de traumas, modalidades de tratamento, tempo de internação e trimestre de atendimento. Foi feita estatística descritiva e análise de cluster. Resultados: A média de idade dos pacientes foi 31,16 anos (DP = 15,17 anos) e o tempo médio de internação foi de 6,32 dias (DP = 7,75 dias). Verificou-se a formação automática de quatro clusters com perfis distintos de pacientes. As variáveis que mais contribuíram para a diferenciação externa entre os clusters foram: tempo de internação (p < 0,001), etiologia (p < 0,001), tipo do trauma facial (p < 0,001), presença de trauma associado (p < 0,001), tipo de tratamento (p < 0,001) e trimestre de atendimento (p < 0,001). Conclusão: A maioria dos pacientes eram homens, vítimas de acidentes de trânsito, que apresentaram fratura do complexo zigomático, submetidos a tratamento cirúrgico. Nível de Evidência III, Estudo Retrospectivo.

ABSTRACT Objective: To describe the profile of patients with facial trauma admitted in a hospital located in a metropolitan area of Northeast Brazil. Methods: A cross-sectional and exploratory study was performed. A total of 244 cases were in agreement with the eligibility criteria. The variables include the sociodemographic characteristics of patients, etiology, type of trauma, treatment modalities, length of stay in a hospital and quarter of care. Descriptive statistics and Cluster Analysis were performed. Results: The average age of patients was 31.16 years (SD = 15.17 years) and average hospitalization was 6.32 days (SD = 7.75 days). It was verified the automatic formation of four clusters with different profiles of patients. The variables which most contributed to the external differentiation between clusters were: length of stay in a hospital (p <0.001), etiology (p <0.001), type of facial trauma (p <0.001), presence of associated trauma (p <0.001), treatment modalities (p <0.001) and quarter of care (p <0.001). Conclusion: The most of patients were men, victims of traffic accidents, which suffered fracture of zygomatic complex and underwent surgery. Level of Evidence III, Retrospective Study.

O osteoblastoma é uma neoplasia benigna e incomum nos maxilares. Em alguns casos esta lesão apresenta características locais extremamente agressivas, sendo denominada osteoblastoma agressivo. Devido às características clínicas, radiográficas e histopatológicas serem similares a uma variedade de tumores benignos e malignos, o seu diagnóstico é um dilema. Este relato apresenta o caso de um osteoblastoma agressivo na mandíbula e discute o diagnóstico diferencial desta lesão. Paciente, branco, 13 anos de idade, foi atendido na Clínica de Estomatologia da Universidade Estadual da Paraíba, Campina Grande, PB, Brasil, queixando-se de aumento de volume assintomático do lado esquerdo de sua face. A tomografia computadorizada de feixe cônico revelou uma lesão óssea hipodensa multilocular, localizada no corpo do lado esquerdo da mandíbula e no terço inferior do ramo ascendente da mandíbula. A hipótese diagnóstica foi de fibroma ossificante juvenil e osteosarcoma. Após exame histopatológico, o diagnóstico final foi osteoblastoma agressivo. Foi realizada ressecção cirúrgica com margem de segurança. Não houve sinais de recorrência após 4 anos de acompanhamento.

Osteoblastoma is a benign neoplasia and is uncommon in the jaws. In some cases, this lesion presents extremely aggressive local characteristics and is termed aggressive osteoblastoma. Because the clinical, radiographic and histopathologic characteristics are similar to those of a variety of benign and malignant tumors, it poses a diagnostic dilemma. This report presents a case of an aggressive osteoblastoma in the mandible and discusses the differential diagnosis of this lesion. A 13-year-old white male sought the Stomatology Clinic at the State University of Paraíba, Campina Grande, PB, Brazil, complaining of asymptomatic swelling on the left side of his face. Cone-beam computerized tomography showed a multilocular, hypodense bone lesion, located in the body of the left mandible and lower third of the ascending ramus. The initial diagnostic hypothesis was juvenile ossifying fibroma or osteosarcoma. After histopathologic examination, the final diagnosis was aggressive osteoblastoma. Surgical resection with a safety margin was performed. There was no evidence of recurrence after a follow-up period of 4 years.

Introduction Adenoid cystic carcinoma (ACC) is one of the most frequent malignant salivary gland tumors, which commonly affects the minor salivary glands of the mouth and is rare in the nose and paranasal sinuses. In the maxillary sinus, ACC can mimic inflammatory diseases and has a poor prognosis. Objective To report a case of a 50-year-old man with ACC of the maxillary sinus whose clinical findings in the alveolar ridge mimicked an oroantral fistula. Case Report An excisional biopsy was performed and histopathologic analysis revealed ACC. Lung metastases and residual tumor in the maxillary sinus were detected by imaging methods. In view of the poor general health of the patient, no new surgical intervention was performed and he was only treated by radiotherapy and follow-up. Conclusion Although rare in the maxillary sinus, ACC should be included in the differential diagnosis of lesions affecting this site.
