Resumo

Objetivo: Os defeitos ósseos das glândulas salivares são entidades raras, geralmente assintomáticas e normalmente encontradas em imagiologia de rotina. Neste caso clínico foi utilizada tomografia computadorizada com reconstrução tridimensional para estabelecer o diagnóstico diferencial de uma área radiolucente unilateral, localizada perto do ângulo mandibular esquerdo, abaixo do canal dentário inferior. Descrição do Caso: Indivíduo do sexo masculino, 71 anos de idade, raça caucasiana, recorreu à Clínica Odontológica da Universidade Católica Portuguesa, para tratamento dentário. Na radiografia panorâmica foi detectada uma imagem radiolucente, localizada na região posterior da mandíbula perto do seu ângulo, de limites bem definidos, unilocular, sem contacto com as raízes dentárias, abaixo do canal dentário. Na ortopantomografia digital a imagem media 12 mm mésio-distalmente. Utilizou-se uma tomografia computadorizada da mandíbula com reconstrução tridimensional para esclarecer dúvidas relacionadas com as dimensões da imagem e sua relação com estruturas anatômicas vizinhas. Conclusão: Os exames físico e imagiológicos realizados, juntamente com a revisão de literatura, permitiram concluir que havia um defeito ósseo no ramo horizontal no lado esquerdo da mandíbula, abaixo do canal dentário inferior.

abstract = "Purpose: Salivary gland bone defects are rare entities, generally asymptomatic and found in routine imaging exams. This paper reports the use of computed tomography (CT) with tridimensional rendering to investigate the differential diagnosis of a unilateral radiolucent area located near the angle of the left mandible, below the mandibular dental nerve canal. Case Description: A 71-year-old Caucasian male subject attended the University Dental Clinics of the Portuguese Catholic University, in Viseu, Portugal, seeking routine dental treatment for oral rehabilitation. Radiographic examination showed a radiolucent unilocular image, well circumscribed, located in the horizontal ramus of the left side of the mandible, near its angle, below the mandibular dental nerve canal. No teeth contact to the radiolucent image was detected. In the panoramic digital radiograph the image had 12 mm mesio-distal width. A CT scan with tridimensional rendering was performed to refine the measurements of the lesion dimension and its relation with other anatomical structures. Conclusion: According to the clinical and radiographic findings and based on the dental literature, it was concluded that the observed bone cavity was a Stafne bone defect, located in the angle of the mandible below the mandibular dental nerve canal.
