ABSTRACT
Osteochondroma of the mandibular condyle has been found in the oral and maxillofacial region rarely. This paper describes a case of osteochondroma of the mandibular condyle in a 20-year-old woman, who was referred to our service with facial asymmetry, prognathic deviation of chin, cross-bite to the contralateral side, changes in condylar morphology, limited mouth opening, and malocclusion. Computed tomography (CT) was performed for better evaluation to the pathological conditions on the temporomandibular joint. Based on the clinical examination, patient history, and complementary exams, the hypothesis of osteochondroma was established. Condylectomy was performed using a preauricular approach with total removal of the lesion. After 3 years of postoperative follow up and orthodontic therapy, the patient is symptom-free, and has normal mouth opening with no deviation in the opening pattern.
RESUMO
Osteocondroma de côndilo mandibular é raro na região craniofacial. Este artigo descreve um caso de osteocondroma de côndilo mandibular em uma mulher de 20 anos que foi encaminhada ao nosso serviço apresentando assimetria facial, desvio de mento, mordida cruzada para o lado contralateral, alterações na morfologia condilar, limitação de abertura bucal e maloclusão. Tomografia computadorizada foi realizada para melhor avaliação da condição patológica da ATM. Devido à base no exame clínico, histórico do paciente e exames complementares, foi estabelecida uma hipótese de osteocondroma. Um procedimento de condilectomia utilizando abordagem preauricular com uma total remoção da lesão foi executado. Após três anos de acompanhamento pós-operatório e ortodôntico, o paciente está livre dos sintomas e tem uma abertura normal sem desvio de padrão durante a abertura.
