Osteochondroma of the temporomandibular joint: a case report

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.

Two-Stage Treatment of Facial Asymmetry Caused by Unilateral Condylar Hyperplasia

“…The possible causes include trauma followed by excessive proliferation in the repair process, genetic causes, increase in functional loading of the TMJ, hormonal influences, arthrosis, infection and hypervascularity (2,7). The differential diagnosis of condylar lesions generally includes condylar hyperplasia, giant-cell tumor, fibroosteoma, myxoma, fibrous dysplasia, fibrosarcoma, chondrosarcoma, osteoma, osteoblastoma, chondroma, chondroblastoma and osteochondroma (8,9). However, the diagnosis of condylar hyperplasia can usually be made by a combination of clinical and radiological findings.…”

Mandible condyle osteochondroma: clinical case report

“…Although frequently found in the general skeleton, it is rarely seen to involve the facial bones [1][2][3][4] . It usually occurs early in life affecting young adults between 10-30years of age but the craniofacial Osteochondroma are frequently seen in older women 5 .…”

A Rare Site Mandibular Condyle Osteochondroma Complicated by Fracture

“…It is most common benign tumor of bone occurring in 3% of population and constitutes 35 -50% and 8 -15% of all benign and primary bone tumors respectively [2,3]. Osteochondromas occur in a bone with embryonic development by endochondral ossification [4] and most commonly occur in metaphyseal region of long tubular bone (femur, humerus, tibia) with rare occurrence in maxillofacial region [5]. Usually osteochondromas are asymptomatic and found incidentally with most common clinical symptom being long standing slowly growing hard mass, but may present with symptoms due to complications like bony deformity, vascular compromise, nerve impingement, fracture, overlying bursa formation and rarely malignant transformation [1,6].…”
