“…The oral and maxillofacial regions are not common sites of OCs, but the embryonic development of the temporomandibular joint (TMJ), by the endochondral ossification, makes this area the most frequent facial site of this type of tumor (2)(3)(4)(5)(6)(7). Differently from long bones, craniofacial OCs occur at older ages with a slow growth, even at the end of puberty, most frequently affecting women in their second decade of life (1,8,9).…”

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.

“…Mouth opening reduction is the most consistent clinical feature of OC [6]. It's rare in the dentomaxillofacial region [7][8][9][10], however, when it occurs, the condyle and coronoid process are frequently the affected sites [7,[9][10][11][12]. Other locations have been reported such as the skull base, posterior maxilla, maxillary sinus, ramus, body and symphysis [7,10].…”

“…Other locations have been reported such as the skull base, posterior maxilla, maxillary sinus, ramus, body and symphysis [7,10]. It has been reported usually at the fourth decade [9,11,13]. However, Walford et al [14] stressed that the second decade is the most suitable for this condition (68%).…”

Objective: This article presents an interesting case of osteochondroma of the the sigmoid notch. Case Report: A 15-year-old female with severe facial asymmetry, malocclusion, open bite and extreme limitation of mouth opening. Panoramic radiography showed an exophytic radiopaque mass arising from the sigmoid notch on the right side. CT images revealed bony proliferation with benign signs causing damage to the articular eminence, condilar morphology and periarticular soft tissue calcifications. Magnetic Resonance confirmed the findings of the CT and revealed modifications on disc morphology. A surgical resection was performed. Conclusion:The OC located at the sigmoid notch presented is probably the rarest site seen in the existing literature.Key words: Osteochondroma; Sigmoid notch; Facial asymmetry; Restricted mouth opening Osteocondroma do sulco sigmoide: relato de caso em uma localização rara RESUMO Objetivo: O presente artigo apresenta um caso interessante de osteocondroma (OC) no sulco sigmoide. Relato do caso: Paciente do sexo feminino, com 15 anos de idade, apresentada assimetria facial severa, mal oclusão, mordida aberta e restrição severa da abertura bucal. A radiografia panorâmica evidenciou a presença de uma massa radiopaca exofítica, partindo do sulco sigmoide do lado direito. Imagens de tomografia computadorizada (TC) evidenciaram a presença de proliferação óssea, com características benígnas, causando alterações na eminência articular, morfologia condilar e calcificação dos tecidos moles peri-articulares. A ressonância magnética confirmou os achados da TC com relação à alteração da morfologia do disco articular. Como tratamento, foi realizada a ressecção cirúrgica. Conclusão: O OC localizado no sulco sigmoide, apresentado no presente relato de caso, é provavelmente a localização mais rara citada na literatura.
