Osteochondroma is a common benign tumor of the axial skeleton. Despite its preference for long bones, osteochondroma may occur in any bone developing by endochondral ossification, therefore it concerns mandibular condyle as well. This lesion is more common in males than in females and it can occur singly or as a part of an autosomal dominant syndrome known as osteochondromatosis. Solitary osteochondroma has a low incidence of sarcomatous change (1%) while patients with osteochondromatosis have a higher risk of sarcomatous transformation (11%). Symptoms of this lesions are mandibular asymmetry, malocclusion with cross-byte, temporomandibular joint intermittent pain hypomobility, clicking, and the presence of a palpable painless mass in the temporomandibular area. Therapy needs a surgical treatment which can consist in a one-stage or in a two-stage surgical approach. Prognosis is generally favourable.
骨软骨瘤是中轴骨骼常见的良性肿瘤。尽管它更常见于长骨,但骨软骨瘤可发生于任何通过软骨内成骨发育的骨骼,因此也可累及下颌骨髁突。该病变男性多于女性,可单发或作为常染色体显性综合征(骨软骨瘤病)的一部分出现。孤立性骨软骨瘤肉瘤变发生率较低(1%),而骨软骨瘤病患者肉瘤转化风险较高(11%)。该病变的症状包括下颌不对称、伴有交叉咬合的错牙合、颞下颌关节间歇性疼痛、活动度降低、弹响以及颞下颌区域可触及无痛性肿块。治疗需要手术治疗,可采用一期或二期手术方法。总体预后良好。
