Osteoid osteoma is a benign bone tumour with self-limiting growth potential occurring in any part of the body. Two rare cases of a pathologically proven osteoid osteoma invading the temporomandibular joint (TMJ) are reported herein. This article also reviews the cases of osteoid osteoma of the craniofacial complex reported in the English-language literature to date. Although the clinical presentation of osteoid osteoma in the jaw differs from that of osteoid osteoma in the more common locations, the radiographic features are similar. In both cases presented, computed tomography revealed a small round osseous lesion with sharp margins in the TMJ. Bone scintigraphy was performed in order to differentiate the lesions from other osseous lesions. Both patients underwent surgical excision of the lesion with immediate relief of the pain. The importance of early recognition of the clinical and imaging characteristics of an osteoid osteoma of the TMJ is emphasized, in order to prevent misdiagnosis and avoid discouraging therapies.
骨样骨瘤是一种具有自限性生长潜能的良性骨肿瘤，可发生于身体的任何部位。本文报告了2例经病理证实的骨样骨瘤侵犯颞下颌关节（TMJ）的罕见病例。本文还回顾了迄今为止英文文献中报道的颅面部骨样骨瘤病例。尽管颌骨骨样骨瘤的临床表现与较常见部位的骨样骨瘤不同，但其影像学特征相似。在这2例病例中，计算机断层扫描均显示颞下颌关节有一个边界清晰的小圆形骨质病变。为了将这些病变与其他骨质病变区分开来，进行了骨闪烁显像。2例患者均接受了病变的手术切除，术后疼痛立即缓解。强调早期识别颞下颌关节骨样骨瘤的临床和影像学特征的重要性，以防止误诊并避免无效治疗。
